Objective Diabetes poses significant public health challenges, with many individuals remaining undiagnosed and at risk of complications. This study aimed to evaluate the performance of decision tree ensemble methods for predicting diabetes onset using the Framingham Heart Study Teaching Dataset and to explore sex-specific risk patterns relevant to AI-driven interventions. Methods We analyzed data from 11,627 participants, incorporating demographics, vital signs, smoking status, medication use, and laboratory measures. Random Forest classifiers were developed to predict diabetes incidence at approximately 6-year (Period 2) and 12-year (Period 3) follow-ups. Class imbalance was addressed using undersampling, oversampling, and the Synthetic Minority Over-sampling Technique (SMOTE). Results The models demonstrated robust performance, achieving an Area Under the Curve (AUC) of 0.856 in Period 2, and moderate predictive ability in Period 3 (AUC = 0.732 in males, 0.786 in females). Key predictors included glucose level, BMI, systolic blood pressure, age, and heart rate. Notably, differences emerged in predictive accuracy between men and women, suggesting potential sex-specific vulnerabilities that merit further study. Conclusion Machine learning approaches, particularly Random Forests, show promise for medium- and long-term diabetes risk prediction, supporting early identification and intervention efforts. Future work should focus on hyperparameter tuning and explainability techniques, such as SHapley Additive exPlanations (SHAP) values, to improve model precision, interpretability, and fairness. Equity-focused strategies remain critical to ensure AI-driven tools benefit diverse populations and do not exacerbate existing disparities in diabetes care.

Sudan's ecological landscape is characterized by various zones, including deserts, semi-deserts, and savannas, which host a diverse array of forests, rangelands, and numerous plant and animal species. However, the sustainable management of these resources is becoming increasingly challenging due to human activities and the impacts of climate change. This article presents the results of a research project focused on monitoring and documenting biodiversity in Sudan's semi-arid regions, particularly emphasizing insect diversity. Insects are vital for maintaining ecosystem health through processes such as nutrient cycling, decomposition, pollination, and acting as natural predators to pests. Field surveys were conducted across three Sudanese states—North Kordofan, Gezira, and Khartoum—to assess the diversity of flora and fauna. Specifically, El Rawakeeb semi-arid land in Khartoum state was investigated, which comprised three sites with varying soil elevations: a hilly site at 420 meters above sea level, a flat site at 416 meters, and a valley site at 411 meters. Researchers utilized direct collection methods and butterfly nets to gather insect specimens, which were subsequently preserved and identified for further analysis. Diversity indices, including Simpson’s Diversity Index, Shannon-Wiener Index, and Margalef Richness Index, were computed to compare the biodiversity of these sites, along with metrics for evenness and species richness. Permanova analysis was carried out for insect variation between the study sites. A total of 1541 insect specimens were gathered from El Rawakeeb, encompassing 34 species distributed across 21 families and 9 orders. The order Lepidoptera exhibited the greatest number of species (35.29%), followed by Coleoptera (20.59%). The orders Neuroptera, Orthoptera and Thysanoptera recorded the fewest species (2.94% each). From the hilly site, 514 insect specimens were collected, representing 9 orders, among which Hymenoptera included 4 species, while Lepidoptera had 3 species, and Odonata, Orthoptera, and Thysanoptera each had 1 species. The highest individual counts were recorded for Copriniklobe (dung beetle), Dacus longistylus (fruit fly), Camponotussp. (carpenter ant), and Anax ephippiger (dragonfly). In a flat site, 484 insect specimens were collected, classified into 15 species, 12 families, and 7 orders. The highest individual counts were noted in four species: Onthophagusnuba (dung beetle), Dacus longistylus (fruit fly), Camponotussp. (carpenter ant), and Anax ephippiger (dragonfly). In a valley site, 543 insect specimens were collected, categorized into 17 species, 16 families, and 9 orders. Insect Diversity in three research sites. Simpson's Diversity Index revealed varying levels of insect diversity across the three sites. The valley site exhibited the highest diversity level with an index score of 0.857, followed by the flat site at 0.826, and the hilly site at 0.819. The Shannon diversity index of 2.22 indicated the highest diversity among the three sites, suggesting a relatively diverse insect community. The relative abundance of insects was greatest in the valley site at 35.24%, followed by the hilly site at 33.35%, and the flat site at 31.41%. The Margalef Richness Index indicated a moderate level of richness in the insects collected from the three locations. Certain insect species were found in some sites but were absent in others. The PERMANOVA revealed notable variations among the three study sites (F = 2.24, p-value = 0.035).

Enset (Ensete ventricosum) is a vital food security crop cultivated in South and South-western parts of Ethiopia. However, enset production and the farming families have been threatened by Xanthomonas wilt and its spread in the farming system. Thus, this study was conducted to investigate the soil fertility and plant management practices association on the incidence of Enset Xanthomonas wilt. Data on soils fertility and diseases from enset based farming clustered into inner, outer and outfield farm zone were sampled and surveyed. The result indicated that soil chemical properties significantly (p≤0.05) varied from inner to outfield farm zone. Significantly maximum nutrients store revealed in inner enset farm zones. Disease incidence reduced from inner to the outfield enset farm zone. Disease prevalence and disease incidence scored 28.5% and 11.6%, respectively depending on altitude and genotypes. Soil fertility levels in the enset inner and outfield plots were varied purposely to cultivate enset products as kocho, bulla or amicho (cooking type). The variations in soil fertility and Xanthomonas wilt incidence was associated with management practices applied for desired enset products. Therefore, management practices in enset based farming, soil fertility and location of enset planting zones found to be major indicators for disease incidence addressing to device control interventions.

Magnesium is essential for the proper functioning of all human cells and is involved in the regulation of neurotransmitter function and neurological function. Acute and chronic hypomagnesemia cause severe neurological symptoms such as neuromuscular irritability, myoclonus, stridor, dysphagia, mainly postural tremor and movement disorders along with vertical downbeat nystagmus. Here we report a case of cerebellar downbeat nystagmus syndrome induced by acute hypomagnesemia (HICS) due to very frequent vomiting in a 75-year-old woman with benign paroxysmal positional vertigo (BPPV). The clinical condition improved with daily intravenous and then oral magnesium supplementation. To our knowledge, this is the first described case of HICS induced by acute hypomagnesemia due to vomiting triggered by a benign peripheral pathology such as BPPV which was then successfully treated once the central syndrome was resolved.

Acute disseminated encephalomyelitis (ADEM) is a monophasic, multifocal, demyelinating, autoimmune disease that affects the central nervous system (CNS). It usually occurs after a systemic infection, usually viral, including certain coronavirus infections. A 27-year-old girl presented with complaints of left interscapular pain, paresthesias and weakness in the ipsilateral upper limb. These symptoms followed paresthesias on the fingertips of her right hand the day before her admission. she was treated two weeks earlier for pneumonia with COVID-19. Her clinical pattern resulted in a moderate weakness of the left limbs associated with tactil and algic hypoesthesia in the lower left limb ascending until the C4 level in the left side. Magnetic resonance imaging (MRI) of the brain and spinal cord showed diffuse spontaneous hypersignals on fluid-attenuated inversion recovery (FLAIR) images at the cerebral level and on T2-weighted images at the spinal level. These imaging lesions coupled with the medical history of a recent COVID-19 infection led to the diagnosis of acute disseminated encephalomyelitis (ADEM) post covid-19. The clinical condition improved rapidly with intravenous (IV) corticosteroid therapy and IV immunoglobulin combined with physiotherapy. ADEM is a demyelinating autoimmune disease which is increasingly reported during this current corona virus pandemic.

Natural food preservatives in the form of herb extracts and spices are increasing in popularity due to their potential to replace synthetic compounds traditionally used as food preservatives. Rosemary (Salvia rosmarinus) is an herb that has been traditionally used as an anti-inflammatory and analgesic agent, and currently is being studied for anti-cancer and hepatoprotective properties. Rosemary also has been reported to be an effective food preservative due to its high anti-oxidant and anti-microbial activities. These properties allow rosemary prevent microbial growth while decreasing food spoilage through oxidation. Rosemary contains several classes of compounds, including diterpenes, polyphenols, and flavonoids, which can differ between extracts depending on the extraction method. In particular, the diterpenes carnosol and carnosic acid are two of the most abundant phytochemicals found in rosemary, and these compounds contribute up to 90% of the anti-oxidant potential of the herb. Additionally, several in vivo studies have shown that rosemary administration has a positive impact on gastrointestinal (GI) health through decreased oxidative stress and inflammation in the GI tract. The objective of this review is to highlight the food preservative potential of rosemary and detail several studies that investigate rosemary to improve in vivo GI health.

In South Asia, land degradation is primarily a monsoon mediated phenomenon restricted to 2-3 rainy months. The overall strategy for land degradation neutrality should (i) favour actions that keep soils covered with residues and (ii) plant kharif (rainy season) crop before the onset of monsoons to provide soil cover. Retention of anchored residues provides surface cover, increases microbial activity, carbon sequestration, and availability of nutrients. Surface retained residues reduce root zone salinization, detoxify phytotoxic monomeric Al in acidic soils and enhance the potential for use of brackish ground water in crop production. Residues covers save irrigation water and overcome the ill effects of poor agronomic and water management practices. Early direct dry seeding in surface retained residues has the potential of making kharif season planting independent of the onset of monsoon rains in South Asia and helps reduce acreages of Kharif and Rabi fallow lands. For improving carbon content in Indian soils, perhaps the most important priority is to devise tillage and crop residue management approaches that promote in situ rain water storage and its use for growing more crops. The paper summarises how crop residues fuel and drive soil functions and related ecosystem services and plant growth.

The main objective of this study was to quantify the influence of sowing date on growth and yield components of hybrid sunflower (Hysun33) cultivar in semi-arid zone. This experiment was conducted during the seasons 2014/2015-2015/2016 at the farm of the College of Agricultural Studies, Sudan University of Science and Technology, Shambat, Khartoum- Sudan. The experiment was arranged in randomized complete block design (RCBD) with four replications and three treatments. Different parameters were considered including plant height, leaf area index (LAI), filled sees number/head, head diameter, dry weight and yield components. The collected data were statistically analyzed. The results revealed that crop sown in May and July showed significant increase in plant height, LAI, head diameter, dry weight, field seed number/head, weight of 100 seeds; yield; and yield components; compared to crop sown in March. However, crop sown in the second season showed an increase in growth and yield components compared to the crop of the first season.

Quantum dots can be defined as semiconductor nanostructures which are artificial in nature and ranges from 2-10 nm in size. These tiny nanocrystals become excited under illumination and emits colors of different wavelength. Quantum dots possess unique properties determined by their structure (hollow or solid), size, shape and composition. Fabrication of Quantum dots is achieved by several methods such as electron beam lithography, epitaxy or by means of colloidal synthesis.

The transition to university can be a stressful time in a student’s life. Recent evidence demonstrates declining mental and physical health in college and university students compared to the general public. A prospective cohort study investigating mental and physical wellness over the course of a semester in a sample of first-year undergraduate students (N=74; 65%F) from nine faculties was completed at a large university in Canada. Sixty-eight (92%) students with a mean (SD, ±) age 18.2 ± 1.1 yrs., weight 67.9 ± 15.5 kg, height, 168.5 ± 11.6 cm and waist circumference 81.3 ± 9.8 cm completed the SF-36V2 quality of life questionnaire at the beginning and end of the semester in Fall 2014. A decrease in vitality (p=0.003), social functioning (p=0.004), emotional state (p=0.014), and mental health (p=0.019) outcomes as measured by the SF-36v2 occurred during the semester. In addition, aggregate mental health significantly declined from the beginning to the end of the semester (p <0.001), while physical health did not change (p=0.242). The importance of promoting and increasing awareness of campus wide mental health strategies should be considered a priority for first year undergrad students. Particularly, because students in their first year may take longer than one semester to adjust to the increased work load and although difficult to speculate it is possible that both mental and physical health would decline over the next (second) semester. Future research should aim for longer study duration.

Background Bronchoscopic lung volume reduction (BLVR) has been applied in COPD patients with heterogeneous emphysema. In this first clinical trial in Vietnam, we evaluated the safety and initial results of BLVR by one-way valve in COPD patients with severe emphysema. Methods We performed a prospective, nonrandomized, single center longitudinal study in 30 stable COPD patients with heterogeneous severe emphysema on CT-scanner, the average age of 65.17 years old, FEV1≤35 %pred., TLC ≥ 100 %pred., RV ≥ 150 %pred. and 6MWT < 450 meters. The Zephyr one-way bronchial valves (PulmonX, Redwood City, CA, USA) with the size of 5.5 mm and 4mm were placed in lobar or segmental bronchi via flexible bronchoscopy. 28 patients were placed only one valve, 1 patient with two and 1 patient with three valves. 23 valves with the size 5.5 mm diameters and 10 valves with the size 4.0mm used. All patients received optimal medical treatment at the time of procedure and during the study period. Outcomes will be assessed at 3 months after treatment include the changes of clinic, and lung function, the occurrence of complications. Results After 3 months, mean CAT scores decreased significantly compared with before procedure (17.73 ± 3.53 vs 20.10 ± 3.58) (p<0.05), with the median change of 2.73 points and the improvement more than 2 points in 76.67% of patients. 6 MWT increased at 3 months with mean 32.13 meters, 93.33% of the patients increased 6MWT, 46.67% of the patients increased 6MWT more than 26 meters. MRC decreased with the median change of 0.5 score. VC decreased by a mean 0.2 (L) (0.42 - 0.02), FEV1 increased by a mean 0.05 (L) (0.04 - 0.05) but not statistically significant (p>0.05); FVC increased by a mean 0.14 (L) (0.01 - 0.28), RV decreased by a mean 0.62 (L) (1.05 - 0.2), TLC decreased by a mean 0.52 (L) (0.77- 2.4) with statistically significant (P<0.05). The early complications were 13.33%, the later complications were 23.34% of the patients. Conclusions The unilateral bronchoscopic lung volume reduction with one-way valve (mainly one valve) in treatment of heterogeneous severe emphysema in stable COPD patients in Viet Nam have shown that this procedure is safe with encouraging initial results.

Background: Patients with Thal (Thalassemia) are presumed to be inactive for many of the same reasons as healthy adults, though there are limited published data to support this claim. The primary aim of this study was to compare physical activity patterns in subjects with Thal to healthy controls as well as to explore the effects of transfusion therapy on physical activity in transfusion dependent patients with Thal. Methods: 37 Thal (23 Thal major, 14 Thal intermedia, 21 Female, 27.3±10.1 years) and 30 healthy controls (17 Female, 28.0 ± 13.7 years) wore an ActiGraph accelerometer for one to two weeks. Results: Thal subjects recorded a significantly fewer total number of steps per day and lower total energy expenditure compared to healthy controls (p=0.001). None of the adult Thal subjects met the recommended 10,000 steps/day as opposed to 27% of healthy adult controls (p=0.004). Thal spent significantly less time in moderate (p=0.03) to vigorous (p=0.005) activities and more time in sedentary activity (p=0.006). Conclusion: It is now clear that Thal spend significantly less time in physically demanding activities than age-matched healthy controls, a result that has long been assumed though not previously documented. Further research is needed to define an appropriate physical activity regimen best suited for patients with Thal while examining its effect on mental and physical health.

Introduction Contemporaneous substance abuse, violence and HIV/AIDS risks (SAVA) result in synergistic negative impacts (syndemic effects). Presence of and risks for syndemic SAVA conditions are common among emergency department (ED) patients, however research on these inter-related processes is limited in sub-Saharan Africa. This study utilizes structural equation modeling to examine the relationships of syndemic SAVA conditions among persons seeking emergency injury care in Nairobi, Kenya. Methods This secondary analysis of a prospective observational study examined SAVA syndemic conditions among non-pregnant, adult ED injury patients able to provide consent at Kenyatta National Hospital. Structural equation modeling using diagonally weighted least squares (DWLS), was used to quantify associations between three latent variables (substance use, HIV risks, violence exposure). HIV risk included partner HIV status, men who have sex with men (MSM), and gay identities; violence exposure covered emotional, physical or sexual violence in the past six months; substance use encompassed positive screening for alcohol use disorder, poly-substance use, injection drug use and injury-related substance use. Model fitness was assessed using the Bentler-Bonett Normalized Fit Index (BB NFI), Goodness of Fit Index (GFI) (>0.9) and standardized root mean square residual (SRMSR) (< 0.05). Covariance between the latent factors was estimated. Results Among 2,368 screened ED patients, 665 were enrolled. Males were 83% of the sample; median age was 30 years (IQR: 24-38). Fit indices using DWLS showed a close fitting model (GFI=0.99, BB NFI=0.95, SRMSR=0.04). The indicator variables had significant loadings on two of the three syndemic factors (substance use and violence exposure, β range 0.10-0.95); in the SEM only MSM status had a significant loading on HIV risk, which was insufficient to confirm the identification of the latent factor. Violence exposure and substance use risk had significant positive covariance (0.30, p<0.001). Discussion and Conclusion This study provides the first available data from ED patients in sub-Saharan Africa on SAVA conditions, showing a co-relationship of violence exposure and substance use but no significant associations with HIV risk. These results can be used to inform programmatic interventions for higher-risk persons addressing synergistic conditions during emergency care.

Background Women’s participation in environmental conservation within patriarchal societies is a critical factor for achieving sustainable development and improved community outcomes. Despite this importance, limited research has examined women’s perceptions of their roles and contributions to environmental conservation. The current study aimed to (1) explore women’s perceptions of their roles in environmental conservation within patriarchal structures, and (2) to document the effectiveness of strategies enhancing their participation. Methods This study followed a phenomenological design, using thematic data analysis. Information was gathered through semistructured interviews, focus group discussions (FGDs), and key informant interviews with technocrats, civil servants, local leaders, and NGO staff. The sample size of the study was 30 participants, obtained using the point of saturation principle. The focus group consisted of 24 participants and 06 Key Informants. The study tools were pretested with a small group before the main fieldwork. Participants were selected using purposive sampling. The size of the sample was guided by data saturation. Results The findings show that although women’s representation in local councils and environmental committees has grown due to the 30% quota requirement, their influence remains constrained by systemic barriers. Political interference undermines technical teams’ conservation efforts, while widespread community ignorance of environmental laws limits compliance. Weak enforcement and corruption, with leaders themselves implicated in destructive practices, further erode progress. Critically, inadequate financing such as subcounties allocating only 600,000 shillings for sensitization, leaves many activities unimplemented, forcing reliance on development partners. Conclusion The study concludes that sustainable environmental stewardship requires not only legal reforms and institutional accountability but also adequate financing and communitydriven strategies that amplify women’s voices and foster collective responsibility.

Indices, based on data such as height and weight in general and in particularly the body mass index (BMI), are often used to assess overweight. However, there is limited capacity to differentiate the amount of fat mass between individuals. This review refers to an anthropometric model called Dahlmann-Body-Analysis (DBA), which uses simple anthropometric parameters to define a Reference Weight (Ref-Wt). It is based on hand circumference as a proxy for the skeletal frame and, in addition, the circumference of the abdomen as a proxy for central obesity. Processed through a network of algorithms, the DBA model enabled to differentiate the Difference Weight – that means the difference between the Actual Weight and the Reference Weight – into fat mass and skeletal muscle mass. The DBA-model resembles the 2-component model of Albert R. Behnke, which he considered as a living functional construct including essential fat. The DBA-model matches with Behnke`s 2-component model insofar, as the essential fat is replaced by a physiological amount of fat tissue. The review summarizes studies to compare DBA-derived data with Metropolitan Life Insurance tables, evaluates DBA-derived fat tissue mass with bioelectrical impedance analysis (BIA) derived results and analyses the meaning of the DBA model in clinical settings to uncover the underlying mechanisms of metabolic syndrome (MetS) pathogenesis with increasing amounts of fat mass. The model offers the opportunity to calculate changes in fat or muscle tissue in an absolute (kg) or relative (%) amount on individuals. The data suggest that the DBA-model has satisfactory prediction qualities for use as a practical tool in public health care.

Honour and shame are central moral constructs within many South Asian communities, yet their psychological internalisation in diasporic contexts remains underexamined. This qualitative study explored how young British South Asian women (aged 18–25; N = 6) understand and negotiate honour in relation to gender, religion, and identity. Semi-structured interviews were analysed using Interpretative Phenomenological Analysis. Six interrelated themes illustrated honour as a gendered and relational system sustained through anticipatory shame, behavioural surveillance, and sexual double standards. Participants described internalised self-monitoring, bicultural identity tension, and strategic resistance through selective compliance and religious reinterpretation. We propose that honour and shame in minority diaspora contexts function as a moral-emotional identity-regulation system characterised by anticipatory shame, relational accountability, and boundary maintenance under racialisation. This conceptualisation advances acculturation and bicultural identity frameworks by arguing that moral emotion, particularly anticipatory shame, functions as a primary mechanism of cultural internalisation, rather than merely an outcome of value endorsement. The findings further illuminate how moral surveillance shapes identity negotiation and psychological wellbeing, with implications for culturally responsive community and clinical practice.

Objective This study aimed to explore the respondents’ reproductive health profiles, examining the physiological and psychosocial perimenopausal symptoms affecting productivity, and identifying occupational needs. It also determined the relationship between menopausal symptoms and the productivity and occupational needs of peri-menopausal women. Methodology A descriptive cross-sectional design was used, surveying 50 women over 40 years old with a validated four-point Likert scale instrument. The instrument undergone content validation, reliability test, and ethical approval. Survey was administered personally and online using purposive sampling. Statistical treatments included weighted mean, F-test, T-test, Pearson r correlation, and ranking. Key results The majority of participants had their first menstruation between 11 to 15 years old and experienced regular menstrual cycles. Most had one child, with an equal number of cesarean and normal deliveries, and reported no pregnancy complications. The study found that participants seldom experienced physiological and psychosocial menopausal symptoms. They agreed on the occupational needs during the perimenopausal period. It was found that physiological symptoms were influenced by factors such as early menarche, cesarean delivery, and pregnancy complications. Additionally, psychosocial symptoms varied based on menstrual status, the number of children, and pregnancy complications, with those experiencing earlier menstruation or complications reporting more intense symptoms. The study revealed a significant relationship between both physiological and psychosocial perimenopausal symptoms, which negatively impacted productivity and increased occupational needs. Women with higher menopausal symptoms expressed a greater need for workplace policies that support perimenopausal women, highlighting the need for tailored workplace interventions for this demographic. Future Direction The study recommends including pap smears and mammograms in annual exams for peri-menopausal women, offering awareness seminars on managing perimenopausal symptoms to reduce workplace disruptions, and suggests future research exploring additional variables affecting perimenopausal women’s health and productivity

Ayurveda is a traditional and scholarly medical system practiced in South Asia since the Vedic period. It integrates science and philosophy to promote a healthy, happy and prosperous life. Ayurvedicbhasmas are classical formulations that contain non-toxic forms of metals and minerals, enriched with therapeutic metabolites. These bhasmas are produced through repeated trituration of metals and minerals with the extracts from potent Ayurvedic herbs, followed by intense heating at temperatures above 650 °C. The preparation process of bhasmas closely resemble top-down approach in nanoparticle synthesis, resulting in very fine calcined nano-powders. These powders are used effectively in Ayurvedic treatments for various ailments, particularly chronic diseases. Recent studies have highlighted that bhasmas possess antioxidant, anti-inflammatory, antibacterial, antiviral and antitumor properties and may serve as potential carriers for drug delivery. This paper aims to compare bhasma particles prepared by traditional and modern methods, explore the therapeutic benefits of different bhasmas, and investigate the nanomedicinal features of various Ayurvedicbhasmas.

It is proposed that the human soul is a manifestation of a soul field consisting of a collection of quantum-like fields. The soul field interacts with the electromagnetic field, manifested by photons interacting with the quanta of the soul field. Evidence for this comes from near-death experiences where reported events that could not have been seen through the eyes of the individual are verified. Since bioelectric fields are a type of electromagnetic field, bioelectric fields may also interact with the soul field. This could result in the transfer of information on working memory content to the soul via interactions with bioelectric fields produced by neural ensembles in the human brain. The soul field may also affect neurons on the molecular level in the brain through interactions with bioelectric fields and the recently proposed mechanism of cytoelectric coupling. The human soul is coupled to the body through its interactions with bioelectric fields in the body. Manifestations of the quantum-like fields comprising the soul field may carry out different functions such as encoding memories and experiences, representing emotion states, and defining personal identity. Interactions of these fields and their quanta could produce emergent properties such as self-awareness and consciousness.

Adolescence in Cameroon, as in many parts of sub-Saharan Africa, is often marked by early childbearing. Studies have shown a national prevalence of adolescent deliveries to be around 14.2% - 14.4%, a higher rate than the average for sub-Saharan Africa This presents a unique challenge for young mothers, who must navigate the complex process of identity reorganization while still navigating their own adolescence with its multiple changes. This article explores the experiences of primiparous (first-time) Cameroonian adolescents as they transition from daughters to mothers. The objective of this article is to understand how identity reorganization takes place among primiparous Cameroonian adolescents who pass without transition from the status of daughter to the status of mother. Drawing on qualitative data from semi-structured interviews, with seven participants chosen on the basis of selection criteria, the article examines the psychological, social, and cultural factors that shape this identity shift. An interview guide with three main themes made it possible to collect verbatim comments from the participants. The thematic analysis highlights the challenges faced by these young mothers, such as navigating social stigma, managing emotional upheaval, and balancing motherhood with their own developmental needs. The findings of this study highlight the complex and multifaceted nature of identity reorganization among primiparous Cameroonian adolescents. The social stigma associated with early childbearing, coupled with the emotional and practical demands of motherhood, can pose significant challenges to these young women. However, a study on a larger sample could reveal the resilience and resourcefulness of some adolescents, who find support within their communities and employ various coping mechanisms to navigate this transition. Finally, the article discusses the implications of these findings for adolescent maternal health interventions and social policy in Cameroon.

COVID-19 vaccine hesitancy has emerged as a major challenge to global efforts to control the pandemic, particularly in Nigeria, where hesitancy to other effective vaccines such as polio and measles has been widely reported. Several individual, societal, and structural factors contribute to this behaviour and prevent the effectiveness of COVID-19 prevention efforts. Objectives This study sought to identify the predictors of COVID-19 vaccine hesitancy in the seven states of North-Central, Nigeria. Methods A population-based cross-sectional online survey was conducted among residents using a semi-structured questionnaire adapted from the WHO SAGE vaccine hesitancy scale and distributed via social media networks over 8-weeks. Results A total of 1,429 responses met the inclusion criteria and were analysed. Among the respondents, 60.7% were males, 47.5% were between the ages of 26 and 45, and 80.1% had postsecondary education. A total of 421 respondents (29.5%) were hesitant and unwilling to receive the vaccine. The reasons for hesitancy were concerns about side effects (37.1%), doubt about the existence of COVID-19 (11.0%), and the perception of time required to receive the vaccine (9.6%). Post-secondary education (AOR: 0.49, 0.36-0.66) and people of the Islamic faith (AOR: 0.68, 0.52-0.90) were found to be associated with lower levels of hesitancy. Conclusion The study found that vaccine hesitancy is a complex problem that is linked with multiple social determinants of health as lower educational attainment, lower income and Christian faith were found to be predictors of vaccine hesitancy. Confidence, Complacency and Convenience factors were expressed by respondents as concerns about side effects, doubt about the existence of COVID-19 and time required to receive the vaccines were the most prominent reasons for unwillingness to receive the vaccine. In order to protect the public health of communities, targeted interventions are required to increase vaccine acceptance by cultivating trust in vaccines, disseminating accurate information, and engaging with community stakeholders including religious groups.

The persistence of multidrug-resistant (MDR) Salmonella Typhi (S. Typhi) is a challenge especially in regions where typhoid is endemic. Surveillance of circulating genotypes of MDR S. Typhi is crucial in typhoid acute cases and carriers. This study aimed to investigate genotypic diversity of S. Typhi from symptomatic and asymptomatic children in endemic settings in Nairobi, Kenya. Symptomatic and asymptomatic individuals’ ≤ 16 years were recruited at four health facilities and tested for typhoid through stool cultures. The S. Typhi isolates were subjected to antibiotic susceptibility testing to investigate multidrug resistance. The MDR S. Typhi isolates’ DNA was extracted and illumina sequenced. Raw reads were de novo assembled and analyzed by pathogen-watch. From the 90 sequenced isolates, 60 (67%) were confirmed to be S. Typhi (sequence Type 1 and genotype 4.3.1). Out of the 60 S. Typhi strains; 39 (65%) had plasmids, from these 38 (97%) had IncHI1 plasmids alone. Out of the 60, 59 (98%) S. Typhi isolates had blaTEM-1D. Point mutations conferring reduced susceptibility to quinolones were detected in 42 (70%) of S. Typhi isolates, from these; 14 (33%) had gyrA S83Y , and 28 (67%) gyrB S464F genes, respectively. This study reports 4.3.1 (H58) as the most dominant S. Typhi genotype responsible for spread of MDR phenotypes carried on IncHI1 plasmids. Presence of MDR S. Typhi with resistance genes such as blaTEM-1Dand reduced susceptibility to ciprofloxacin especially among asymptomatic individuals, reiterates the need for use of typhoid conjugate vaccine among vulnerable children as a control and prevention measure against typhoid.

Amyloid fibrils, which are caused by abnormal conformation and the mis-assembly of proteins, are responsible for several conformational diseases, including prion diseases. To develop methods to prevent amyloid formation, blocking peptides with hydrophilic substitutions covering the stem forming regions of barnase 1-24 were prepared and examined for their ability to block amyloid-forming fragments—prion, Amyloid β, Pmel 17—. When these fragments were mixed with the synthetic blocking peptides, the result was a decline in the intensity of fluorescence, suggesting that amyloid formation was inhibited. Therefore, amyloidogenesis appears to be specifically inhibited by disrupting the hydrophobic interactions between core amyloid regions.

The instructional techniques in neuroanatomy laboratories continue to evolve to incorporate online interactive resources to improve student experience and outcomes. This study aims to design an “all in one”Virtual Interactive Brain Atlas (VIBA) that provides students with an educational resource that will improve their knowledge of neuroanatomy while in the brain lab and provide them with lab resources they can self-study and self-test. Coronal, midsagittal, whole brain, and horizontal brain slices were used to create detailed descriptions, interactive features, and quiz assessments to create VIBA. Upper level undergraduate and optometry students taking a neuroanatomy one-semester course were provided with VIBA for use during the semester. A paper survey was distributed after completing the course to determine student perception. No significant difference was indicated between the student groups regarding their self-reported understanding prior to the brain lab (p= 0.194) and after the brain lab (p= 0.308). There was a significant difference between the student populations when stating that they strongly agreed that the online brain atlas improved their understanding of neuroanatomy (p= 0.032) and that the VIBA tool was easy to navigate (p=0.048). There was a significant difference between the two student groups that strongly agreed that the online brain atlas quality was sufficient (p= 0.015). This online interactive brain atlas was created in a time-efficient manner from readily available models and was well received by experienced neuroanatomy faculty and students.

Waterborne diseases pose a significant global public health threat, particularly in sub-Saharan Africa, where frequent outbreaks occur. These diseases stemming from contaminated drinking water, poor waste management, and insufficient hygiene contribute to high morbidity and mortality in children under 5 years old. A study addressed waterborne diseases in N'Djamena, Chad's 3rd and 9th districts, through decision-making strategies. The research employed various methods, including a household survey using questionnaires, workshops, semi-structured interviews, and focus group discussions. Additionally, documentary research provided essential data for analysing the situation of diseases in the community. Epidemiological data from 2019- 2022 indicated a substantial prevalence of diseases such as diarrhoea, dysentery, skin infections, typhoid, abdominal pain, and malaria, with notable mortality, especially among children. Among surveyed households, 50% believed the consumed water was contaminated, attributing it to faecal matter, while 28% and 22% linked the diseases to inadequate hygiene and unsanitary conditions, respectively. The study advocates for comprehensive strategies, including improving water treatment efficiency, implementing safe waste management, promoting hygiene, and vaccination. Active involvement of all stakeholders, with municipal authorities leading, is crucial for effective implementation and combating waterborne diseases.

Camels are a significant source of income for nomadic populations in many developing countries, including Ethiopia. Camels are well adapted to dry and semi-dry regions, providing income, food security, and transportation. However, camel production and productivity are constrained by infectious diseases, such as brucellosis, which is a highly infectious bacterial disease that affects camels and humans worldwide. Brucellosis causes significant economic losses due to abortion, low herd fertility, and decreased milk production. In Ethiopia, the prevalence of camel brucellosis varies depending on factors related to the host, agent, climate, and management system, with a reported prevalence ranging from 0.5% to 11.9%. Accurate diagnosis of camel Brucellosis is essential for herd-based screening of animals. Although culturing the pathogen is the preferred method for diagnosis, serological tests such as Rose-Bengal plate test (RBPT), Enzyme-linked immunosorbent assay (ELISA), and Complement fixation test (CFT) and polymerase chain reaction (PCR) assays have been developed. Implementing effective diagnosis and surveillance systems to control the spread of brucellosis in animals and humans is very important, on top of awareness campaigns, vaccination programs, and suitable laboratory establishment recommended. Continued research is essential to maintain the health and productivity of camel populations, particularly in pastoral areas where camels play a significant role in the livelihood of communities. Therefore, the present paper views the seropositive prevalence and potential risk factors associated with camel brucellosis in Ethiopia.

Nutrition during pregnancy is of utmost important to ensure positive pregnancy outcomes after delivery. This study examined the utilization of nutrition services provided at health facilities to pregnant women. A cross sectional study design, involving 105 pregnant women and 5 RCH providers from 2 health facilities was used. Structured questionnaires, and structured observations were used in data collection. SPSS software version 25 was used in data analysis. Results showed that, RCH providers had inadequate nutrition knowledge due to limited nutrition courses during nursing training and on job trainings/seminars. All RCH providers advised that, nutrition knowledge is important to pregnant women hence they were responsible for its delivery. In adequate staff and lack of teaching materials contributed to the poor delivery of quality nutrition education to all pregnant women as it was observed that there is variations in nutrition information given to women. More than a half of all pregnant women (63%) started their ANC clinic during their first trimester where they received all nutrition services including education on importance of nutrition during pregnancy which helped them to be aware of the relationship between diet maternal nutrition and birth outcomes (63.8%). Most common food group that has been consumed more by pregnant women was grains, roots and tubers and plantains, while also there was high consumption of fruits and vegetables by all women as they are being more emphasized during routine clinics to prevent anemia. Also, there are some barriers that were identified by the service providers which makes their work difficult such as inadequate teaching materials like brochures, posters and jobs aids, also shortage of staff was found to be the core cause of services being provided occasionally as it is the RCH nurse who provide the education and counselling as there is no any nutritionist hired by government at the facility. Regional and district nutrition officers should coordinate and conduct on job training to health providers on issues related to nutrition in order to update their nutrition knowledge and facilitate clear, accurate and more evidence based nutrition information delivered.

DADA2 (deficiency of adenosine deaminase type 2) is an autoinflammatory autosomal recessive disease resulting from biallelic loss of function mutations in ADA2 gene. Clinical presentation and age of onset vary widely even among related patients, and variability of symptoms and severity manifestations include bone marrow failure, autoinflammation, immunodeficiency and vasculitis. Here, we report a case of young male with adult onset DADA2, who presented with fever, lower limbs skin rash, joint pain, and anemia resembling systemic lupus erythematous (SLE). DADA2 has an extremely variable clinical phenotype. It was described into three categories: inflammatory/vascular, immune dysregulation, and hematologic. However, the data is scant in describing autoimmunity phenotype in DADA2 and further studies are required to investigate the clinical correlation and presence of autoantibodies. We recommend genetic testing in cases with lupus-like disease especially if there is consanguinity between parents and family history of vasculitis.

The synthesis of II-VI semiconductor nanocrystals doped with transition metal ions is particularly difficult. In the case of manganese doped CdSe nanocrystals produced via chemical route it is necessary to achieve small incorporation of manganese ions. The incorporation of manganese ions in CdSe nanocrystals has been confirmed by the study of Energy Dispersive Spectroscopy, Photoluminescence and Electron Paramagnetic Resonance spectra. The CdSe nanocrystals have cubic structure, the average crystallite size lies between 3-6 nm and increases with the variation of doping concentration of Mn2+ ions as characterized by X-ray diffraction. The structural properties of CdSe semiconductor nanocrystals are also studied by High Resolution Transmission Electron Microscopy, Scanning Electron Microscopy and UV- Visible Absorption Spectroscopy. The energy band gaps have been determined by UV/V is absorption study with the help of Tauc plot and are 2.54 eV, 2.27 eV and 2.24 eV as concentration of Mn2+ions in CdSe semiconductor nanocrystals increases from 0% to 0.75%. The crystallite size is also obtained from the UV-Visible absorption study; this varies from 1.69 to 1.78 nm with increase of Mn2+ concentration from 0% to 0.75% which is in agreement with X-ray diffraction result. Further, the magnetic and electronic properties of Mn2+ doped CdSe nanocrystals are studied using EPR spectra and the values of g factor, second-rank axial zero-field splitting parameter D and hyperfine parameter A are calculated. EPR measurements reveal that the dopant ions are incorporated in CdSe semiconductor nanocrystals.

The increasing demand for environmentally-friendly materials has led to a surge in research on the production of biodegradable polymers. In this study, we investigate the synthesis of a biodegradable polymer by graft copolymerization of gum Arabic (GA) and polyethylene glycol (PEG). GA, a natural polysaccharide and PEG, a synthetic water-soluble polymer, were used as the backbone and graft monomer, respectively. The graft copolymerization was carried out using benzoyl peroxide as an initiator and performed under nitrogen atmosphere. The resulting polymer was characterized by Fourier transform infrared (FTIR) spectroscopy, Xray diffraction (XRD), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The FTIR spectra confirmed the formation of the graft copolymer, and TGA analysis showed that the copolymer had higher thermal stability than GA. The DTA thermograms indicated two thermal events. The evaporation of water and organic polyethylene glycol components was measured, and the first mass loss was due to the loss of adsorbed and structural water in the gum Arabic, which occurred between 31.87 and 180°C, while the second, corresponding to the pyrolysis of polyethylene glycol functional groups and polysaccharide decomposition, resulted in a 70% mass loss. SEM morphological analysis of gum Arabic showed aggregates of high irregularity in particle shape. The cracks and holes obtained in the Gum Arabic micrograph disappeared from the new gum Arabic-graft-polyethylene glycol, leaving a smooth surface with scattered particles in the image, which was due to the grafting copolymer. From the XRD patterns, the percentages of the amorphous and crystalline phases were determined. The results show that gum Arabic has a 78% degree of crystallinity, whereas gum Arabic-graft-polyethylene glycol has the lowest value of 51%. Biodegradation activity was observed using the fungus Aspergillus flavus on different days on gum Arabic-g-polyethylene glycol. The results clearly showed inhibition zones with a change in the state of the copolymer from solid to liquid from days 8 to 14. These results indicate that the GA-PEG copolymer has potential as a biodegradable material for use in various applications, such as packaging, agriculture, and medical industries.

Background of this paper investigates dogonyaro-leaf-extract as inhibitor for aluminum corrosion in 0.3-M hydrochloric acid, and its acceptability as original. In the methods, the extract was analyzed for phytochemicals and corrosion test performed on aluminum sheet before immersion in acid incorporated extract. Electrochemical Impedance Spectroscopy (EIS), tests were performed over frequency of 100 KHz–10 mHz and 10 mV peak to peak perturbation amplitude to obtain the corrosion potential. Tests were run at 30oC ± room temperature in aerated quiescent solutions. In weight loss method, coupons were suspended in aerated solutions before immersion in 20% mixture of sodium hydroxide and zinc dust to stop further corrosion. Morphology of the mirrorlike finished arid surface aluminum was measured with scanning electron microscope SEM. In the results, various phytochemicals were observed; significant effect of incorporating inhibitor on EIS data recorded and optimum extract efficiency was 99.46%, at 10 g/l, 60oC, within 6 hours. This result was validated and 99.3% efficiency obtained. Introduction of extract into acid corrodents caused increase of charge transfer resistance and reduced double layer capacitance. A warm arid clean coupon evolved after SEM test. In conclusion, there was increase in efficiency of inhibition as inhibitor concentration and temperature increased. Similarly, close responses towards the factors for Inhibition occur. Measured polarization showed that extract inhibited both cathodic and anodic reaction processes and thus, is classified as mixed type inhibitor. The investigations thus proved the extract as excellent corrosion inhibitor for aluminum in 0.3-M hydrochloric-acid.

Moyamoya disease is a very rare chronic circulatory occlusive disorder of the blood vessels of the brain, in which patients complain of headache, seizure, weakness, and sometimes paralysis. A 5 years old female child with a complaint of headache and seizure was admitted elsewhere and during the treatment, she was diagnosed with Moyamoya disease. Further, she went to AIIMS Patna, where the neurosurgeon advised Digital Subtraction Angiography (DSA) and after the final diagnosis, they suggest the surgical intervention of the brain. During the search for an alternative treatment, they consulted my center for Unani treatment. We advised a semiliquid Unani polyherbal formulation containing Gule Banafsha (Viola odorata), Ustukhuddoos(Lavandula stoechas), and Nilofer (Nymphaea alba Linn) for three months. After the completion of the treatment schedule, she went for DSA again in Patna AIIMS and they find that there is no sign of occlusion in the blood vessels of the brain. The patient has no complaints and the report also showed that she gets improved.

Although pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV infection, only around 25% of at-risk individuals in the United States have accessed a prescription. One way to increase PrEP uptake is through the sexual health screening of patients and linkage to PrEP in primary care settings. The objective of this analysis was to assess the barriers and implementation strategies during a screening and linkage to PrEP pilot intervention. Primary care patients were screened for PrEP indication during routine primary care visits. Of the 1,225 individuals screened, 1.8% (n=22) were eligible for PrEP and from those, 77.3% (n=17) attended the specialist appointment and were prescribed PrEP. Primary care patients (n=30) and providers (n=8) then participated in semi-structured interviews assessing their experience with the pilot intervention. Using an applied thematic analytic approach, patients and providers identified barriers and related improvement strategies that could be classified into four main categories: 1) Financial Barriers: Individual- vs. Clinic-level Considerations 2) The Role of Stigma, Discomfort, and Cultural Factors 3) Logistical Hurdles and Streamlining the Intervention, and 4) The Lack of PrEP Knowledge and the Need for Education. Findings support the accepatability and feasibility of screening for PrEP in primary care along with appropriate implementation strategies. This study suggests that because of the high volume of patients seen in primary care, sexual health screenings and linkage to PrEP interventions have the potential to reduce new incident HIV infections among diverse sexual minority men.

The motivations and barriers experienced by community health workers (CHWs) during the delivery of maternal and child health (MCH) services are less documented in Rwanda. This study aimed to explore the barriers and facilitators of implementing MCH care as perceived by CHWs. A descriptive qualitative study was conducted, and Semi-structured interviews with flow-up probing questions were used to collect data. A number of 24 interviews were conducted with CHWs from three selected sectors of the Gicumbi district including four supervisors of CHWs from each selected health center and one at the district hospital. Three focus group discussions with CHWs from each site were also conducted. Ethical approval was obtained from Mount Kenya University and permission to collect data from the study sites was granted. NVIVO software was used for analysis, and then the content analysis was adopted to identify themes merging from the interviews and focus group discussions. The study findings revealed emerged factors that facilitate the CHWs to deliver MCH services to their communities: liking their work, trust by the community, respect from the community, the willingness to help, desire to gain knowledge, being human, and sacrifice for the wellness of the community. On another hand, the findings indicated that the work of CHW has various barriers including working many hours, lack of equipment, lack of knowledge, unsatisfactory salary, heavy workload, lack of working space, lack of facilitation for communication, family conflicts, lack of specified working time, and believes.

In this research work Mg0.45Mn0.55-xNixFe2O4 ferrite particles of varying compositions (x=0.05, x=0.15, x=0.25, x=0.45 and x=0.55) were synthesized using cost effectual co-precipitation route. The synthesized ferrite particles were characterized by collection of techniques. XRD analysis confirmed the formation of cubic spinel structure of the ferrite particles. SEM and AFM analyses illustrated the morphology and size distribution of obtained ferrite particles. FT-IR study exposed that the absence of any additional peak related to second phase. VSM results indicated magnetic analyses such as saturation magnetization (MS), Coercivity (HC) and Remanence (Mr) of ferrite particles. The major objective of the present investigation is to synthesize MgMnNiFe2O4 ferrite particles on cotton fabrics in order to obtain finished fabrics; it is very significant in biological applications. The antibacterial activities of the ferrite particles coated cotton fabrics were tested against selected Gram positive and Gram negative bacteria which showed tremendous results via formation of inhibition zones. The fabricated ferrite particles on cotton fabrics showed great durability evidenced by their antibacterial activities even after 20 washing cycles. Hence, the functionalized cotton fabrics could be used as potential antibacterial agent.

Introduction Pre-exposure prophylaxis (PrEP) is an element of the biomedical interventions of Human Immunodeficiency virus (HIV) prevention. The level of protection is strongly correlated to PrEP drug adherence. In Nigeria, the prevalence of HIV among female sex workers (FSW) is 15.5%. The 2020 integrated biological and behavioral surveillance survey did not report on PrEP adherence among FSW. This study therefore assessed the level of adherence to PrEP and its predictors among FSW in South-Western Nigeria. Methodology This cross-sectional analytical study was conducted in 2021. Study population were brothel-based FSW at Gambari Ogbomoso and Lagos, Nigeria. A total of 156 FSW participated in the study. Data was collected using interviewer-administered semi-structured questionnaire and analyzed using IBM SPSS Version 25. Results One hundred and forty-nine properly completed questionnaires were analyzed. Ninety-nine respondents (66.4%) have been working for more than 5years as a FSW and 65(43.6%) had initiation of sex work before 18 years of age. Respondents’ sexual behavior showed that 55 (36.9%) of total respondents had consistent use of condom. One hundred and thirty-four respondents (89.9%) had good knowledge of PrEP, 97 (65.1%) had good attitude towards PrEP while 111 (74.5%) had good perception of risk of HIV infection. One hundred and thirty-two (88.6%) reported to be taking PrEP and 119 (79.9%) had good adherence to PrEP. Predictors of adherence to PrEP were educational status, age of commencement of sex work and monthly income. It was found that educated sex workers were 2.67 times more likely to adhere to PrEP (OR=2.67, 95% CI=1.280-5.591, p=0.019). Those who commenced sex work after clocking 18 years of age were 75% times less likely to adhere to PrEP (OR=0.251, 95% CI=0.106-0.597, p=0.001) while those with average monthly income more than #10,000 were 1.65 times more likely to adhere to PrEP (OR=1.65, 95% CI=0.674-4.042, p=0.0275. Discussion and Recommendation The level of adherence to PrEP is considerably high and underscores a positive effect of the efforts of the Government of Nigeria in controlling HIV as a threat by 2030. Further studies would be useful to understand the behavioral factors associated with low adherence to PrEP among FSW who have spent more than 5 years in sex work.

Rainfall is one of the most important components of the hydrological cycle. The importance of rainfall in arid and semi-arid regions is more apparent. Due to the important role of rainfall trend assessment in the proper management of water resources, in the present study, Khorasan Razavi province, the second-most populous province of Iran located in the northeast of the country, for this purpose was studied. Currently, this region is facing water shortage problems. In this study, the non-parametric Mann-Kendall method was used to evaluate the annual rainfall trend over a thirty-year period from 1989 to 2019. On the other hand, Sen's slope estimator method was used to determine the magnitude of the rainfall trend in the studied synoptic and rain gauge stations. The results showed that the root of water shortage problems is not due to drastic changes in rainfall. Therefore, water shortage problems in Khorasan Razavi province are mainly due to a lack of proper management (i.e., mismanagement). The present study, by examining the rainfall trend using an appropriate framework, tried to take an effective step towards improving the management of water resources in the northeast of Iran.

Objectives This study aims to evaluate the challenges of implementing non-pharmaceutical interventions, assess adherence, accessibility to prevention materials and identify requirements for the control of the spread of COVID-19 among individuals living in a slum-setting in Lagos, Nigeria. Methods This is a five-month cross-sectional study conducted in Makoko, Lagos an urban-slum community. Data on sociodemographic characteristics, living conditions and adherence to COVID-19 prevention strategies were obtained with a semi-structured questionnaire. Logistics-regression model was used to determine factors associated with adherence to COVID-19 preventive measures. Results There was a total of 357 participants who had a mean age of 45.8 ± 12.9 years. Majority were males (62.2%), married (83.8%), self-employed (66.4%), and had secondary education (31.4%). Most participants (93.8%) had no space for self-isolation as majority lived in a one-room apartment (72.8%), shared toilets/kitchen space (64.4 %), had no constant source of water supply (61.9%) and buy water (62.5%). About 98.8% are aware of the COVID-19 pandemic but only 33.9% adhered. Most of the participants disclosed inability to purchase face masks/ hand sanitizers (68.9%). After adjusting for covariates, the ability to afford facemasks/hand sanitizers (P < 0.0001, aOR 6.646; 95% CI: 3.805-11.609), living alone (P < 0.0001, aOR 3.658; 95% CI: 1.267-10.558), and ability to buy water (aOR: 0.27; 95% CI: 0.14-0.50), had greater odds of association with adherence to the non-pharmaceutical COVID-19 preventive measures. Conclusion The lack of isolation space among majority of the respondents calls for concern. Inability to purchase prevention materials is a major factor influencing poor compliance to COVID-19 prevention strategies.

Thin films are everywhere in the modern world, with many of the technologies we depend upon in daily life being, in turn, dependent upon thin film technology. Chemical bath deposition includes principles of chemical bath deposition (CBD) and concept of solubility product, nucleation and film growth, thin film deposition mechanism in chemical bath deposition. The non-metallic ion source (anions) and metal ion source (cations) then react to form the compound. The nucleation process plays an important role in determining the crystallinity and microstructure of the resultant film. From the discussion of deposition techniques which are physical and chemical deposition methods. Physical deposition techniques contains sputtering deposition, electron beam evaporation and physical vapour deposition (PVD) process have been known for over 100 years and also fabrication films on the substrate, as well as the increasement of the pressure in the chamber due to operation of the sources indicates directly that gases or vapors are desorbed. Chemical deposition process is economically effective and has been industrially exploited to large scale. It can be summarized that thin film characterization techniques include X-ray diffraction (XRD), UV-Vis spectrophotometer, scanning electron microscopy, energy dispersive x-ray diffraction, transmission electron microscopy (TEM). X-rays diffraction (XRD) is a rapid and a powerful technique used to study the phase of a crystalline material, information on unit cell lattice parameters, crystal structure, crystal orientation and crystalline size.

Aim There is limited published data describing the characteristics of the paediatric population prescribed semi elemental formulas. This retrospective observational audit aimed to describe the characteristics of the paediatric patients who have been prescribed a hydrolysed whey protein, medium chain triglycerides (MCT) based formula, Peptamen Junior® and the nutritional outcomes. Methods A retrospective observation audit was completed on a cohort of patients that was prescribed a semi elemental formula between 2016 and 2019 from a single tertiary paediatric medical centre. Data variables were collated such as patient characteristics, indications and modalities of administration, duration and tolerance to the formula. Results Data was collated on 375 patients with a median age of 6.2 years. The main underlying medical conditions were haematological/oncology (67%), gastrointestinal disorders (10.7%) and neurological conditions (9.4%). The most common indications for use were chemotherapy related side effects (36.2%), post bone marrow transplant (25.8%) and gastrointestinal symptoms (17.9%). The formula was rarely used as a sole source of nutrition, with 88% patients requiring accompanying forms of nutrition support. The majority of orders prescribed were of standard concentration (80.8%) and tolerance was recorded in 82.8% of patients. Conclusion The semi elemental formula Peptamen Junior® appears to be well tolerated in paediatric patients with a variety of medical conditions that have complex pathologies and may have wider scope of use in a more diverse group of medical conditions than currently indicated.

This paper attempts to present the dissemination and transmission dynamics of emerging and reemerging infectious diseases and the underlying features of gain-of-function research and geopolitics in the ambient within and across borders. Research and publication are relevant from perspectives in the management of local and global health because disease is perspicuously a geopolitical issue ostensibly linked to gain-of-function research where health diplomacy undergirds present and future global functionalities regarding the emergence and reemergence of infectious diseases. These have generated vehement reactions with propensity for extreme geopolitics and gain-of-function natural and anthropogenic activities. Geopolitical parameters and gain-of-function issues impact on the social determinants of health and vice versa. The convening and convergence of countries for unprecented epidemic or pandemic treaty settings or other formulations to confront emerging and reemerging infectious diseases will afford considerable opportunities concerning challenges in action, preparedness and response. Provisions are pertinent for legal instruments, effective and efficient systems to curb future threats and outbreaks of infectious diseases.

This review focused on the various methods for controlling estrous cycles in well-managed dairy cows. Because up to 70% of dairy cows may stay non-pregnant after an AI procedure, an effective approach for identifying and reinseminating open cows is essential for dairy herds to achieve optimal reproductive performance. Overall, well-managed dairy farms with effective estrus detection programs inseminate 50% or more of non-pregnant cows after behavioral estrus is detected. Cows not detected in estrus are admitted in a resynchronization of ovulation procedure to receive a timed AI (TAI) service to avoid a long interbreeding interval. In Egypt, a widely used program involves starting the Ovsynch protocol (GnRH-7 d-PGF2-56 h-GnRH-16 to 20 h-TAI) 32 days after an initial AI, regardless of pregnancy status. Previous studies have proven that there was no difference in pregnancy/artificial insemination (P/AI) between Ovsynch+P4 and Presynch-Ovsynch, both protocols were equally effective in improving the fertility of cows with a CL 15 mm. The review also addressed different methods for synchronization of ovulation and different factors affecting the selection of the management program.

In this theoretical discovery of a law of Life, there is MATHEMATICS (Geometry, Bits and Numbers) that UNIFY 3 universes as complementary as ATOMIC MASS, WAVES, and INFORMATION (DNA, RNA and Amino Acids). The discovery of a simple numerical formula for the projection of all the atomic mass of life-sustaining CONHSP bioatoms leads to the emergence of a set of Nested CODES unifying all the biological, genetic and genomic components by unifying them from bioatoms up to 'to whole genomes. In particular, we demonstrate the existence of a digital meta-code common to the three languages of biology that are RNA, DNA and amino acid sequences. Through this meta-code, genomic and proteomic images appear almost analogous and correlated. The analysis of the textures of these images then reveals a binary code as well as an undulatory code whose analysis on the human genome makes it possible to predict the alternating bands constituting the cariotypes of the chromosomes. The application of these codes to perspectives in astrobiology, cancer, and specifically in INFORMATION THEORY with the emergence of binary codes and regions of local stability (voting process), whose fractal nature we demonstrate, is illustrated. PREFACE by Professor Luc Montagnier Addendum by Robert Friedman M.D After the discovery of the DNA double helix structure allowing both the stable storage of genetic information and its transfer through messenger RNA to protein synthesis organelles themselves structured by RNA most abundant in cells, the ribosomal. This wonder of nature exists in ALL living beings from the virus to humans and is based on two codes, the linear sequence of nucleotides and that derived from codons where three nucleotides allow with a certain flexibility - synonymous codons - the choice in the twenty amino acids. But we are missing a third CODE the one governing at multicellular beings from the rotifer to human, the stabilized modulation of gene expression in a nutshell the differentiation of cells from the single cell of the fertilized egg. It is logical to think that this program which begins as soon as fertilization is written in the DNA. We are also prone to associate it with non-coding DNA sequences although they control gene expression. I introduce here the notion developed by Jean-Claude Pérez of mathematical harmony, a higher order present in all living beings and whose existence it finds in genomes, including those of viruses. Thus the natural evolution of variants of the genome of coronavirus Covid 19 tends towards increasingly long Fibonacci series. It remains to determine the Who, the How and the Why of such developments. I will bet with my mathematician colleague that waves and fractals play a role. Luc Montagnier ADDENDUM Jean-claude has given scientists a strong new direction for research. He has identified a unified field of science guided by the Golden Ratio and Fibonacci Sequence. By identifying an overall guiding principle that makes possible fractal-like nesting at all levels of biological manifestation, future researchers can begin with the "whole" instead of the "parts". If we know that complex systems are organized at varying levels by the Golden Ratio and Fibonacci Sequence, we can look for those universal patterns first and then fill in the gaps with small details to complete the picture. It's like having an overall view of a crossword puzzle before beginning to assemble the individual pieces. Without an overarching vision and guiding principle, completing the puzzle is infinitely more difficult. Once scientists and researchers realize and begin using this "SECRET IN HIDDEN IN PLAIN SIGHT," their discoveries will be orders of magnitude more fruitful. Robert Friedman M.D

Oxidative stress is implicated in male infertility and significantly higher reactive oxygen Species (ROS) are detected in 25% of infertile males. We showed that Ozone oxygen therapy (O2/O3) induces protective effects for oxidative stress factors and its consequences on isolated mitochondria obtained sperm which may provide insight into the role of Ozone oxygen in human infertility. The present study was carried out to further characterize and compare protective effect of Ozone oxygen on isolated mitochondria obtained from sperm. Semen was collected from human normal donors. We gained human sperm mitochondria by differential centrifugation and isolated mitochondria incubated with different concentrations (5µg/ml, 30 µg/ml, 80 µg/ml) of O2/O3. O2/O3 prevent significant decrease in reactive oxygen species formation and mitochondrial membrane potential collapse on isolated Human sperm mitochondria. Ozone oxygen therapy induced increase in ATP concentration on isolated mitochondria. Our findings showed that O2/O3 prevent toxicity in sperm, effect on mitochondrial respiratory chain and avoid to cytochrome c release and apoptosis signaling.

Rotenone is well known environmental neurotoxin used to induce Parkinson’s disease (PD) model. Numerous studies are investigated its toxicity on the brain but few studies are available that examined its toxicity on the liver and kidney. Therefore, the main aim of the present work was to explore the toxicity of rotenone on the liver and kidney and its protection through quercetin. Administration of rotenone orally at the dose of (5mg/kg b.w daily for 60 days) caused a significant increase in the levels of liver function and renal function biomarkers as compared to controls. A significant increase in the level of lipid peroxidation, nitric oxide, and decrease in the levels of reduced glutathione, reduction in the activities of catalase and superoxide dismutase were observed in the liver and kidney as compared to control. The histopathological and SEM study in rotenone-treated mice showed alteration and signs of inflammation in the liver and kidney. While co-treatment of quercetin orally (30 mg/kg b.w for 60 days) together with rotenone, reversed the above parameters. In conclusion, rotenone significantly damages the liver and kidney, and the administration of quercetin along with rotenone shown a protective role. This study provides a new insight into where rotenone-induced liver and kidney dysfunction could be successfully protected by quercetin.

Phenomenology is a ritual of Qualitative research methodology. Interviews in healthcare enables researchers to recognise and understand data from lived experiences of the participants by using Phenomenological approach. The purpose of this article is to review the various face to face in depth interviews conducted using Husserl’s descriptive, Heidegger’s interpretive phenomenology or Hermeneutic phenomenological approach in healthcare. The in-depth interview will help to understand the health issues and ethical issues faced by participants. Methodology Four articles were selected based on phenomenological approach. Article.1 was based on Hermeneutic Phenomenology approach. In this study thirteen women were taken as sample. Sampling was done by snowball method. The women were asked to share their rural maternity experience. Data was analyzed without any influence of the researcher. Article.2 was based on Transcendental phenomenology. There were 15 students from 4 different cultural background belonging to different health professional programmes like nursing, medicine, pharmacy, dentistry, and physical therapy. Triangulation methods were used and semi structured interviews were conducted, recorded and transcribed. Health professional students shared their lived experience with patients. Article.3 was based on a study conducted using both Transcendental phenomenology for patients interviews and Hermeneutic phenomenology for healthcare professionals’ interviews. The semi structured interview of patient was taken to understand and record their lived experience with the medication without any bias or interpretation and data received was bracketed. The healthcare professionals’ interviews were conducted on Hermeneutic strategy regarding the medications they prescribe for life threatening illnesses. Article 4 was based on Hermeneutic phenomenological approach. There were nine patients selected and in depth semi-structured interviews were conducted. The patients shared their experience of living with a life limiting illness.

Introduction Reporting of suspected or confirmed communicable diseases is paramount. Although physicians have primary responsibility for reporting, school nurses, laboratory directors, infection control practitioners, daycare center directors, health care facilities, state institutions and any other individuals providing health care services are also required to report communicable disease. Therefore, community health needs assessment in urban communities remains an essential instrument for the rapid and accurate dissemination of epidemiological information on cases and outbreaks of diseases under the national health regulations and other communicable diseases of public health importance, including emerging or re-emerging infections. Purpose of the Study Todescribe relevant medical needs of townspeople so that treatment plans can be developed accordingly. Methods The Study was a cross-sectional with qualitative approach. In-depth interviews and focus group interviews was used as research technique. Data was categorized to look for emerging themes then further distilled to identify any abstract themes that could be understood holistically. Results Urban decision-makers need to advocate the problem of human resources in public health facilities and the mutual health insurance to revise its insurance policy to allow their clients to be received even in private clinics. Dental services was wished to be available in public health centers. Study participants suggested that new useful information could be posted in private public premises rather than to be in public institutions only. Conclusion The patient waiting time, dental services in health centers, and the way of dissemination new health information, mutual health insurance and insufficient human resources are the major concerns of townspeople that they wish improvement.

Aim Community-based psychosocial support centers for cancer patients and their relatives (CBPSCs), developed in the Netherlands, offer easily accessible contacts with fellow patients and support by trained volunteers. We studied the characteristics of visitors of CBPSCs, which palliative support they need and receive, and how satisfied they are with this support. Methods The role of 20 CBPSCs was explored in semi-structured interviews among 34 visitors with regard to their contacts with CBPSCs on palliative care (study 1). Additionally, in 25 CBPSCs, 701 visitors filled out a web-based questionnaire about their experiences with the palliative care (study 2). Within this second study, 25 coordinators of CBPSCs also answered questions about the palliative care (study 3). Results The cancer patients and proxies stressed the view that palliative support should be a part of the support by CBPSCs. This belief was confirmed by the coordinators. Not only attention to the reduction of symptoms, but also emotional support and information supply should be offered when recovery is no longer possible. Talking about death and dying may be worrying for some visitors in a better condition. Education of the volunteers is needed, taking into account the conditions in the CBPSCs e.g., the already existing experience with the palliative care in the CBPSCs and participation in regional networks. Practical Implications Further development of the attention given to palliative support, training and research in that field is needed.

Background COVID-19 as an infectious disease, and deadly biological crisis, threatens the bio-psycho-social- spiritual health of the people. Spiritual health from the perspective of Islam, means having a sound heart, living in the present time with sense of peace, security, patience and gratitude, safe from the fear and anxiety of future, grief and regret for the past events. It affects other dimension of health. This study was conducted to investigate the spiritual health services in the face of the COVID-19 pandemic in a Muslim society. Methods This qualitative study was conducted from March 1, 2020 to the end of May 2020 in Tehran by using the Schwartz and Kim's hybrid model concept analysis with a deductive / inductive analysis approach, in three stages: 1- Theoretical review of religious and scientific evidence, 2- Field research 3- Final analysis. Data collection was done in hospitals and hospices by semi-structured interviews, taking notes, websites and social networks search. Data were analyzed by "Contractual Content Analysis Method". Results Despite the fact that spiritual health services (spiritual care and counseling) are not taught in Iranian universities, but in this biological crisis, spiritual health services, based on religious beliefs of health system employees were implemented. The Muslims’ belief in divine test, healing power of God, helping the people as highest worship, aroused spiritual awakening and enthusiasm in the health care team. Spiritual health services at prevention levels were provided with the aim of helping the patient, family and clients, in an inter-professional model based on the jurisprudential rules derived from the religious evidences (Verses and Hadiths), in line with holistic approach, community-based care, spiritual self-care, home-care, family participation. The involvement of non-specialists in the provision of medical services was prevented. According to, preserving the human dignity in Islam, Islamic rituals were performed by the treatment team and volunteer clerics for dying and dead people. Conclusion Considering the impact of religious spirituality on Muslims’ lifestyle and health behaviors, it seems that the use of Islamic health guidelines can improve the quality of health care services and help improve the spiritual health of people in biological crises.

The paper describes the development of a long-lasting product for Intra-domicile residual spray (IRS) and shows it is possible to obtain a residual effect of nearly 2 years. However, to obtain that the methods currently recommended by WHO for laboratory evaluation had to be modified and approached methods closer to the semi-field and field evaluations as applied in later phases of WHO procedures. Surfaces with high pH resulted in short residual effect unless the formulations were mixed with a silicone coating. Screening in huts constructed for the purpose was realised by dividing the wall surfaces in 25 test plots of 0.5 m² where formulations were applied randomly with more repeats the closer to the final formulation. Mud and concrete surface were more challenging than wood surface and stones and these could be dropped for screening. Wall surfaces heated by sun were repellent to non-blood fed mosquitoes, and the test in huts were limited to the mornings. However, blood fed mosquitoes were not repelled. Cone tests on mud-walls are complicated by the uneven structure of the surface and a better way of attaching cones to avoid mortality errors was developed. Formulations that can be applied and last for two mosquito seasons produce big cost savings for IRS programs, since program costs are mostly application costs.

Background Women play an important role in the work setting. This leads them to put off their motherhood, sometimes preventing them from getting pregnant. Delaying pregnancy face women with low ovarian response, such as in Premature Ovarian Insufficiency (POI) or Ovarian Aging (OA). There is no current treatment, although there is evidence of improving ovarian function by inyecting mesenchymal stem cells (MSC). Materials and Methods Prospective, observational study of 17 women who attended Pronatal Clinic from 2019 to 2020. Each patient was registered in Assisted Reproductive Treatment (ART) and was enrolled in ovarian treatment with an autologous adipose tissue Mesenchymal Stem Cell (AD-MSCs) protocol. Three groups were assembled: 1) Control: AMH >1.2 ng/mL, without AD-MSCs, 2) POI/OA: female infertility due to POI/OA with AMH <1.2 ng/mL and 3) Amenorrhea: female infertility due to POI/OA with amenorrhea and AMH <1.2 ng/mL. Variables: Age, weight, height, serum AMH, endometrial thickness, follicular size and number on day 2 and 11 of the menstrual cycle, oocyte number, number of blastocysts and pregnancy rate. Results Between month 2 and 5, after AD-MSCs inyection, POI/OA group showed an increase in follicle number (2 to 9) and size (13.5 to 15.5 mm) on day 11 of the menstrual cycle, which resulted in a higher number of MII oocytes (2.6 to 4.2), and an increase in number of blastocysts (0 to 3) and endometrial thickness (8.6 to 9.4). Regarding the Amenorrhea group, a reboot in menstrual cycle was observed, although no further development of blastocyst was found. Conclusion The AD-MSCs inyection directly in the ovary allowed an increase in number of blastocysts and improved pregnancy rates in POI/OA patients.

Background Breast cancer is one of the most common types of cancer affecting women globally. It has shown increasing morbidity and mortality rates over the past years. Several screening methods ranging from simple breast self-examination to a highly sensitive test procedures for early detection and treatment are available, but uptake is a challenge. Lack of a national screening programme in the country makes available regional screening programme unsuccessful. This study aims to assess the factors affecting the uptake of breast cancer screening programme among female staff in a tertiary hospital, Southwest Nigeria. Method This descriptive cross-sectional study involves 375 participants selected by a stratified random sampling technique, with proportional allocation to population size and the use of a semi-structured questionnaire. Respondents were questioned on their basic knowledge of breast cancer symptoms, risk factors and treatment, over a score of 50 and above, were set as the cut-off mark to determine good knowledge of breast cancer. Patients attitudes towards breast cancer screening as well as factors affecting uptake were also measured. Descriptive statistical analysis was done using SPSS-20 while the predictors of the uptake of screening were determined using logistic regression at p ≤ 0.05. Results There were 360 respondents, comprising of 13.3% clinical and 86.7% non-clinical female staff within the age bracket of 20 to 58 years (38.2±0.42 years). Out of the respondents, 97.8% have heard about breast cancer but only 52.3% had been screened while 65.5% had “Good knowledge” of breast cancer. Positive attitude to breast cancer screening was displayed in 52.5% while over 90% claimed to be practicing breast self-examination. Only 36.1% of respondents above 40 years old have had mammography done. Most frequent barriers to screening uptake include cost, poor accessibility to screening facilities, shyness (unfamiliar screener), unavailability of female doctors, careless attitude, fear of cancer and other more pressing family problems. Using logistic Regression at p ≤ 0.05, females with a negative attitude, young unmarried (less than 30years) and lack of easy accessibility to screening facilities were significant factors affecting uptake of breast cancer screening services. Conclusion Due to knowledge-uptake gap of breast cancer screening revealed in this study. It is therefore obvious from these findings that a concerted effort is needed to actively remove these barriers by repeated education, training and re-training strategies among health workers and to improve their uptake and level of advocacy and campaign for breast cancer screening among their patients and clients.

Introduction HIV prevention services to in-school adolescents need good planning and management. HIV risk reduction interventions are geared toward measuring sexual risk behaviour outcomes of adolescents that predispose them to HIV infection. The sexual behaviour of adolescents, especially in-school adolescents should be assessed in the process. Adolescents have been identified as the most vulnerable group for acquiring human immunodeficiency virus (HIV) and other sexually transmitted diseases (STDs) and as such, measures should be taken to prevent them from infection. One important reason for higher HIV prevalence among adolescents, especially girls, is the frequent practice of age-discrepant partnering, where older men, who are more likely to be infected with HIV, form sexual partners with younger girls. The objective of this study is to assess the knowledge and sexual behaviour of in-school adolescents in the prevention of HIV and AIDs in rural areas of Abia State. Materials and Methods This is a descriptive cross-sectional survey that was conducted between January and March 2020. Information was collected from 66 students of a community secondary school in the state. Participants were selected by a multi-stage sampling method and data were obtained using a semi-structured pre-tested questionnaire. Results Respondents consisted of 40(60.6%) females and 26(39.4%) males with ages ranging from 13 to 19. Some of the respondents 28 (42.4%), are living with parents while 24(36.4%) live with close relatives. A good number of the respondents 39(59.1%), accepted that their friends are HIV positive. Majority of them 49(74.2%) have not been approached for sexual relationships. About 17(25.8%) of the respondents accepted that they have boyfriends and girlfriends. Out of this number, 12(18.2%) of them said they have been approached for sex and only 2(3%) of them accepted having sexual relationships with the opposite sex. Finding showed that only 1(1.5%) of the respondents claimed to have ever used condoms during sex. Of the sexually active respondents, 49(74.2%) of them are aware that HIV is a virus infection caused by having multiple sex partners while 14(21.2%) were not sure whether HIV is a virus or bacterial infection. Conclusion The study revealed a gap in the knowledge of HIV prevention as well as inappropriate sexual behaviour among the respondents. Therefore, meaningful strategies that will be culturally sensitive to modify adolescent sexual risk behaviours should be adopted.

Background This study focused on nutritional status of the rickshaw pullers, their dietary energy and nutrients consumption along with their energy intake gap as compared to expenditure. Methods A cross sectional study was carried out at 15 different important locations of Dhaka city during December-January 2018. In total, 670 rickshaw pullers from these locations were randomly selected. Printed predesigned and validated semi structured questionnaire was used to record necessary information. Nutritional status was determined according to Asia specific BMI cut- off values. Energy expenditure was calculated using their Basal Metabolic Rate (BMR) and Physical Activity Level (PAL) value. 24-hour dietary recall method was administered for dietary analysis. Results About 65.4% of them were found within normal BMI range. About 11.5% were underweight and about 23.1% were found having more than normal BMI. Percentage of both underweight (39.0%) and overweight (35.8%) were found higher among those who were between 25 and 35 years. Average daily dietary energy consumption was 2391 kcal and energy expenditure were found 4608 kcal. Their energy consumption was found 2217 kcal less compared to their energy expenditure. Conclusion The current study revealed the nutritional status, dietary intake of the rickshaw pullers of Dhaka city and found energy gap in their dietary intake compared to their expenditure. For their better health and nutrition outcome integrated approach should be taken by the responsible authorities.

Background Evidence based message design and efficient dissemination of messages are critical to the success of tobacco control mass media campaigns. Although evidence to measure effectiveness of messages is emerging within low -and middle-income country (LMIC) settings, evidence-based approaches for mass media message dissemination is currently lacking due to challenges in accurate assessment of gross rating points (GRPs) for efficient delivery of campaign messages. Approaches to more accurately predict optimal campaign impact are required to achieve best-buys in resource constrained settings Method A case study approach compared findings from two national tobacco control mass media campaigns implemented in Bangladesh. Stage one reviewed protocols to assess the efficacy of message designs. Second stage analysis involved a review of the mass media campaign recall findings from cross-sectional, post-intervention surveys. Last, a post assessment of GRPs for both campaigns was conducted to support the development of an algorithm to better predict campaign impact at the greatest cost-efficiencies. Results Message mean pre-test scores identified that the Baby Alive campaign scored approximately 20% lower than mean pre-test scores of messages for the Graphic Health Warning campaign. Media dissemination for the Baby Alive campaign was also relatively low at 165GRPs achieving 16.8% prompted recall while the Graphic Health Warning campaign delivered 292GRPs to achieve 47.0% prompted recall. The analytic-predictive model identified that for messages with high pre-test scores an increase of only 1.5GRPs was required to the existing media plan to potentially achieve an additional percentage point of recall. Discussion Given the weaknesses in GRP calculations in LMIC settings, analysis of multiple metrics should be considered to achieve best buys for tobacco control mass media campaigns. Based on optimal message mean pre-test scores of 90%+ and delivery of 292GRPs, which achieved 47% campaign recall, optimal recall of 70% could be predicted with a media plan delivering 342GRPs. More analytical-predictive mass media programming models need to be developed in other LMIC settings examining multiple campaign findings to confirm if this algorithm can provide better returns on investment with efforts directed toward delivering interventions that are supported by a strong evidence base.

Objectives Aim of the study was to develop a ‘composite body size score’ (CBSS) using anthropometric traits to estimate body size and to assess the nutritional status of each study individual on the basis of CBSS. Materials and Methods Data on seventeen anthropometric traits were collected from 710 individuals (Male, Female) from fishermen community inhabiting coastal villages of West Bengal, India. For estimating body sizes, Structural Equation Model (SEM) was constructed with Path Analysis (PA). Later, second order Confirmatory Factor Analysis (CFA) was applied on SEM to determine CBSS. It was hypothesized in the models that CBSS is composed with three sets of latent variables viz., linear, circular and skinfold, constructed from anthropometric traits. Applying new derived optimal cut off points of CBSS was used to determine lean, normal and robust body sizes. Individuals with negative values of CBSS were categorised as lean body size,. Positive values of CBSS were categorised into two categories- normal and robust body size. Results On the basis of CBSS, result showed that 50.6%, 48.8% and 0.6% of the individuals were categorised under lean, normal and robust body size respectively. Females showed relatively higher percent of lean body size i.e. under nutrition (73.8%) compared to males (26.2%). Conclusion The hypothesized model estimate more accurate composite body size score, based on anthropometric traits. All the traits are highly significant on the model. The lean body size category can be use in predicting ‘Undernutrition’.

The composites of Cu, Carbonyl iron (CI), carbon nanofiber (CNF), graphite nanoflake (GNF)/polypyrrole (PPy) and [(Cu-CI-CNF-GNF) 0.5-PAA]-PPy0.5 were synthesized via different methods by in-situ polymerization on the surface of nanoparticles (NPs) with core-shell structure. This paper describes a method for polyacrylic acid (PAA) coating of NPs in aqueous solution. Then PPy coating was performed by template polymerization on NPs-PAA. Morphology, magnetic and conductivity properties were observed via scanning electron microscopy (SEM), vibrating sample magnetometer (VSM) and four probe method, respectively. The microwave characterization of nanocomposite was evaluated through arch test based on a network analyzer. The PPy nanocomposites possessed the excellent microwave multi absorbers properties in 2-18 GHz. It was also found that nanocomposites with 50% w/w and light weight exhibit good microwave absorbing properties in 2-3 GHz and 5-14 GHz frequency, so can be used to cellphone, radio frequency and radar shielding.

Background Nutritional status of adolescent girls is very crucial for their health and has a great impact on the quality of the next generation. The present study aimed to investigate the nutritional status and nutrition-related knowledge among urban adolescent girls in Bangladesh. Methods A cross-sectional study involving a total 500 of adolescent girls (aged 10-19) from four schools and colleges in Dhaka city. Socio-demographic, anthropometric and nutrition-related information was collected by semi-structured questionnaires. In addition, 24 hours food recall and food frequency questionnaire was used to assess the dietary intake. Results The ages of the early adolescent and late adolescent girls yrs (Mean ± SD) were 12±1 and 17±1 respectively. The mean (±SD) BMI of the early adolescent and late adolescent was 21.12±0.32 and 22.10±3.89 correspondingly. Among the early adolescent girls, the nutritional knowledge score was about 62% (moderate), 87% had a positive attitude and 72% had good practices in their daily lives. Whereas among the late adolescent girls, the nutritional knowledge score was about 57% (moderate), 90% showed a positive attitude and 61% had good practices. Among the subject, the average calorie intake was 1491 kcal, which was 24% lower than RDA. The Carbohydrate intake was lower than the RDA but the protein and fat intake was higher than the RDA. Conclusions The dietary intake of adolescent girls was found inadequate. Nutrition education and strong motivation can create positive changes in dietary intake. To understand the real phenomena of dietary intake of adolescent girls, further study is necessary to conduct with a large sample size.

Background Self-medication (SM) can be defined as the use of drugs to treat self-diagnosed disorders or symptoms, or the intermittent or continued use of a prescribed drug for chronic or recurrent disease or symptoms. A number of individuals in developing countries do not attend physicians for their illnesses; instead they commonly use self-medication. Self-medication could be using drugs existing in home like over the counter (OCT) drugs, traditional medicine, prescription only drug. Self-medication is not always bad, hence for the over the counter drugs it is beneficial. Inappropriate storage and use of medicines at home could have a direct influence on public health, the environment and the health-care services and it increases the risk of self-medication. Objective To assess the practice of self-medication and drug storage among South Sudanese community in Addis Ababa. Materials and Methods A cross sectional study design was conducted in Addis Ababa city from April 22 to April 26/2019. Data was collected by semi structure-questionnaire consisting questions on general demographic, socio-economic as well as on perceived illness/ symptoms in the past four weeks and actions taken for it. The data collected was screened before it is analyzed. Data analysis was done by using calculator. Results From the total 297 respondents 286 (96.2%) had reported self-medication in the last one month before the study period. The most common types of ailments for which the respondents reported to have practiced self-medication were cough, cold and sore throat 90(30.3%), followed by headache 66(22.2%), diarrhea 52(17.5%) ,abdominal pain 47(15.8%), fever 21(7.07%) and vomiting 10(3.3%). The reasons given for self-medication were; the illness was minor 226(76%) and previous experiences with similar ailments 31 (10.4%) were found to be the two major reasons given by the respondents for self-medication in this study. The majority of the respondents 242(81.4%) who practiced self-medication obtained information on self-medication from friends and 29(9.7%) obtained information from family members. The most frequently used group of drugs used for self-medication were analgesics/antipyretics 177(59.5%) and antimicrobial which account 75(25.2%) each followed by antihelmenthics 24(8.08%).The main source of drugs for SM was in pharmacy 220(74.07%) followed by leftover drugs 41(13.8%) while drug retail outlet, and neighbors and relatives were the suppliers to 12.13% respondents each. Conclusion and Recommendation A significant number of respondents (96.2%) use S/M from those perceived illness. Majority of the self-medicated individuals used due to minor illness. The most common category of drugs used was analgesics/antipyretics and antimicrobials. And the reason reported for using S/M was minor illness and previous experience with the illness. Most of respondents obtained drugs easily from pharmacy. So, pharmacies are the major sources of drugs used for S/M. The increased of drugs storage to treat similar illness/symptom and drugs left over from previous use contribute to the increase in the S/M practice. Common drugs store reported by respondents who store modern drugs were analgesic/antipyretic. Most of the respondents stored the drug in locked cabinets. A lot is need to be done in educating the public including the health care providers on the type of illnesses that can be self-diagnosed and self-treated, the type of drugs to be used for S/M, and the proper use of drugs. During dispensing of drugs emphasis should be given to all drug consumers and dispenser because of resistance and side effects of drug is the main challenging problem even in the world. Food, Medicines and Healthcare Administration and Control Authority (FMHACA) needs to effectively implement laws on drug handling and dispensing so as to take necessary measures on illegal providers of drugs.

Acute malnutrition affects nearly 52 million of under five years children globally, 75% of them live in low to middle income countries. The treatment of acute malnutrition using supplement foods could help children recovering and could reduce the risk of sickness. The present study investigated the factors associated with recovery among children with moderate acute malnutrition (MAM) under a follow-up program at health facilities. A prospective study was conducted in 16 health centers of Kirehe District of Rwanda and included 200 children from 6 to 59 months. A semi-structured questionnaire was used for data collection. All children enrolled in the study spent three months in nutrition program at health centers. The results show that after 3 months in the program 77.5% recovered from MAM. Children aged above 36 to 59 months were recovered at 90% whereas children aged from 24-35 months were recovered at 73.5%. Micronutrients and deworming provided at health facility were contributed to the recovery as children who received them were recovered at 89.1% and for those who didn’t were recovery at 72.1%. The findings demonstrated that boys were 16 times more likely to recover from MAM in three months of intervention than girls (AOR=16.19, p<0.001, 95% CI: 5.39- 48.63). Children from moderate income families were 3 more likely to recover than those from very low income families (AOR=2.8, p=0.029, 95% CI: 1.11-7.51). Male gender, receiving micronutrients and deworming from health facilities and family income status were factors associated with MAM recovery status

Introduction An adequate nutrition pattern is of major importance for one’s health and well-being, especially during pregnancy when a woman undergoes major biological, physical, psychological and social transformations. Macronutrient and micronutrient deficiencies predispose the fetus to preterm birth, neural tube defects, and low birth weight for gestational age. This study was conducted to determine the nutrition awareness of women in childbearing age in order to provide a greater understanding of the life course perspective (LCP) in relation to nutrition behaviors and pregnancy. Methods A cross-sectional study was conducted on based on our conceptualization of nutrition awareness and questionnaire based studies of a face-to-face interview. The participants were women with age group of 17 years to 45 years participate in studies in Jeddah city. Data collection procedures A Semi-structured questionnaires prepared in English language were translated in to Arabic and then translated back to English to check for consistency. The questionnaires were pretested Human ethical committee; the questions assessed respondents’ nutrition knowledge. Results and Discussion Different questions were asked to 175 selected pregnant women to be included in this study assess knowledge of pregnant mothers on nutrition and determinant factors in the study area. Most of the respondents (34.85.2%) were in 19-25 years of age group.69.1 % (n=121) women says they pay attention to the number of soft drinks they drink each day. There would be fascinating to study awareness of specific nutrients and related issues, like consumption folic acid, non-vegetarian diet, minerals and life style such as mental stress and physical exercise.

Since the independence of South Sudan, Sudan lost 75% of its oil reserves, this led to major fuel shortages country wide, the fuel shortage raised the fuel prices and the overall transport prices. Scarcity led to black market trade of fuel specially in states away from the Capital City (Khartoum). Managing the available stock comes first before increasing the supply amount in order to solve the problem, one of the major fuel consumers to be managed is the transport sector specially the long haulage freight transport. Moving freight in Sudan is constrained by inadequate infrastructure and high costs. This paper covers specifically the long haulage freight transport between Khartoum State and Western side of the country (Darfur Region), Contributing to manage fuel consumption for trucks, taking into account trucks types used, roads, environmental impacts and mitigation measures applicable to save fuel . The results showed that the primary reason for the excessive fuel consumption is the usage of the rigid trucks (lorries) for transport specially the Hino700 series, this truck type, overload and absence of weight stations and control policies contributed significantly to deterioration of roads and transport efficiency decreasing. First step towards the solution would be in upgrading roads infrastructure assuring high quality along with enforced weight regulations and weight stations to protect roads from damages. High quality roads shall ease the usage of different truck types with different configurations. Then stablish a policy to force replacement of the low efficiency lorry truck types with high quality tractor semi-trailer combinations.

Background The mammary glands are the second most common tumor development site in female dogs. One of the ways of staging such tumors is to evaluate the presence or absence of distant metastasis, including in bone marrow. Such findings in human medicine are associated with poor survival of women with breast tumors. However, in veterinary medicine, this clinical staging is used more for patients with lymphomas and mastocytomas. Studies using bone marrow biopsies as a staging method for mammary tumors are scarce. Objectives The present study was to evaluate mammary lesions and bone marrow in 23 female dogs, searching for disseminated tumor cells or metastatic foci. Results: Grade I carcinoma in mixed tumors was the type most observed (22.4%), and there was no statistical difference in relation to tumor size or presence of metastasis in lymph nodes. In the bone marrow of one female dog with carcinosarcoma (4.35%), there was cytoplasmic marking of a probable disseminated tumor cell of epithelial origin, and immunohistochemical evaluation showed presence of cytokeratin-19 antibodies. None of the female dogs presenting reduced cellularity or medullary fibrosis, confirmed through Masson’s trichrome technique, had cell marking in immunohistochemical analyses. Conclusions Bone marrow evaluation can be used as a staging method for mammary gland tumors in female dogs, since disseminated tumor cells present the potential to become secondary lesions and to disseminate to distant foci, thereby causing tertiary metastases over an indeterminate period of time.

This paper attempts to answer the question of whether digital terrorism, also known as cyberterrorism, exists. The paper defines terrorism both in the conventional and digital sense. It then gives a short history of conventional terrorism, dating back two thousand years and ending with the terrorist activities in several third-world nations. The essay then discusses digital terrorism, highlighting the Estonian, Georgian, and Ukrainian cyber-attacks. The work concludes that digital terrorism does indeed exist, but that the future is uncertain in the sense that future cyber-attacks will probably not resemble past attacks as the technology advances.

Nanocomposites are worn resistant materials used in cutting tool applications. The materials are composed of ultrafine powder hard phase grains surrounded by a tough binder phase carbon nanotubes (Mo2C)1-x–(TiC)x (2≤x≤4)//1Wt% SWCNTs. Composite bicarbide Mo2C-TiC was rapidly synthesised and simultaneously consolidated by field activated sintering technique (spark plasma sintering) at which the extensive volume expansion occurred as a function of the volumic fraction from 20 to 40 vol.% of TiC powders and 1 Wt.% of SWCNTs was reinforcement of the NCMC’s. The sintered powder mixture was examined by XRD patterns, the morphology of the obtained phase was observed by SEM and the phase compositions in different regions were analyzed by EDX. The composites were processed using Field Activated Sintering Technique, spark plasma sintering (SPS) at temperatures in the range of 1700-1800°C with addicting of SWCNTs. The effects of SWCNTs addition on phases morphology, microstructure hardness and fracture toughness of the nanocomposite were investigated. The best product contained 1.0 Wt% SWCNTs from (Mo2C)1-x–(TiC)x , x= 0.2 which was sintered at 1700°C, 70 MPa for 10 min, M0.8T0.2/ 1 Wt% SWCNTs exhibit a better density, highest hardness and good ductility. Relative densification was achieved 99.5 % from the theoretical and good mechanical properties like hardness and fracture toughness (KIC=5.6 Mpa m1/2) are improved. The results were confirmed using Raman scattering resonant spectroscopy.

Plants have played a significant role in maintaining human health and improving the quality of human life. Therefore, this present study seeks to evaluate the role of its alkaloid fraction in the hypothalamic-pituitary-testicular axis after dichlorvos poisoning in mice. A total of 25 male mice, weighing approximately 20-30 g, were randomly assigned into 5 groups of 5 mice each (Groups A, B, C, D and E). Mice in groups A served as control and received normal saline while groups B, C and E. received 5 mg/kg of dichlorvos daily for 14 days. Mice in group D received 200mg/ kg of Alkaloid extract of Mimosa pudica (AEMM) for 14 days. At the end of the experiment, all animals were sacrificed and Hypothalamus, Pituittary and Testes were excised for histological process. Sperm from cauda epididymidal duct on one side was collected and used for spermatological studies and data were expressed as mean± SEM. Significant difference was set at p<0.05. Results showed significance difference (p<0.05) in sperm motility, sperm life death ratio groups when compared with their controls and no significance difference in sperm volume when compared with control. Histological studies reveal distortion in hypothalamuss, pituitary and testes in dichlorvos administration group compared with control rats while mimosa showed a ameliorative effect when co-administered with dichlorvos. In conclusion, the alkaloids from Mimosa (AEM) leaves enhanced the released of gonadotropins by the cordial action of the hypothalamus-pituitary axis for the reversed of Dichlorvos effect.

Aim This cross-sectional study assessed the nutritional status of ethnic reproductive women aged between 15-40 years, comprising 85 lactating women (LW) and 86 non-pregnant-non-lactating women (NPNLW) who lived in various parts of three hilly districts (Bandarban, Khagrachari and Rangamati) of the Chittagong Hill Tracts (CHTs) of Bangladesh. Materials and Method Research tool was pretested semi-structured questionnaire for this observational study. Anthropometric indices like weight, height and mid-upper-arm-circumference (MUAC) were used in assessing the nutritional status. Results Most (44.4%) of the ethnic women were Marma, followed by Chakma (39.8%), Bam (8.2%) and Tripura (5.8%). No significant (P>0.05) differences were observed in socio-economic variables between LW and NPNLW. Overall, mean age of the women was 28 (±7.2) years; mean family income was 18,822.2 (±3091) BDT and majority (86%-87%) were reported to be food secured throughout the year. Mean Dietary calorie (2631±798 kcal) intake of both groups were up to the mark according to the recommended dietary allowances (RDAs) and most (80.3%-86%) of them also possessed good nutritional knowledge. However, no significant (P>0.05) differences were observed in dietary calorie intake and nutritional knowledge score between two groups of women. Overall, most (68.4%) of the women had normal body max index (BMI kg/m2), 11.7% were found to be undernourished or thin and 19.9% were overweight. It was noticed that better nutritional status of LW and NPNLW were significantly associated with literacy (P<0.05), occupancy in household chores (P<0.05), better income (P<0.05), food security (P<0.05), recommended calorie intake level (P<0.05) and better nutritional knowledge score (P<0.05). Conclusion This study showed that vast majority of the ethnic reproductive women of CHTs are in better nutritional status with normal BMI (kg/m2) and daily calorie intake according to RDA. Most of them were food secured and their nutritional knowledge score was also up to the mark. Better socio-economic condition, nutritional knowledge and accurate calorie intake play a vital role in achieving healthy nutritional status of the two women groups of CHTs.

Aging mammalian skeletal muscle satellite cells (MuSCs) undergo a decline of stem cell/progenitor cell proliferative and regenerative capacity, and the development of a physiological milieu characteristic of a state of chronic sterile inflammation. p38αMAPK and ERK1/2 are two major signaling pathways that regulate the age-associated decline of MuSC proliferative capacity. In this review we propose the following mechanism that links the p38αMAPK pathway to the decline of self-renewal and regenerative capacity of aged MuSCs: a) the HS-FGF-2-FGFR1-p38αMAPK-Axis, a tightly linked homeostatic signaling complex, is in synchrony with the autoinhibition of FGFR1; b) autoinhibition contributes to the Axis’ regulation of the homeostasis of P-p38αMAPK activity in juvenile MuSC; c) this combination of protein-protein interactions is characteristic of a juvenile cytoplasmic milieu of beneficial P-p38αMAPK activity and d) includes Sprouty1 inhibition that supports the stimulation of FGF-2 --> miR-29a; e) the miR29a dismantles the basement membrane in preparation for the initiation of replication; f) an age-associated impaired, dysregulated, over-sulfated heparan sulfate ligand (HS)-FGF-2 fails to activate FGFR1 in aged MuSCs; g) this uncouples its regulation of p38αMAPK and ERK1/2 pathways and results in desensitization of FGFR1; h) desensitization of FGFR1 and Sprouty1 interaction in aged MuSC uncouples their regulation of P-p38αMAPK in the aged MuSCs; i) this enables a state of chronic sterile inflammation to promote and sustain an increased level of P-p38αMAPK activity; and, j) the increased activity of P-p38αMAPK in aged MuSC stimulates the production of cell cycle inhibitors, miR-1 and miR-133, thereby attenuating the expression of the cell cycle regulators, SP1 and cyclin D1, resulting in a G1/S arrest; j) the increased level of p38αMAPK activity promotes the apoptosis of the aged activated MuSCs. This mechanism involves the synergistic interactions of HS-FGF2-FGFR-1, Sprouty (spry1), miR-1, miR-133 and miR-29a that unify the extracellular niche and intracellular milieu for the juvenile vs age-associated regulation of proliferative capacity of the MuSC. Our hypothesis unifies these interactions with the role of the extracellular niche and intracellular milieu in the stimulation of juvenile proliferation vs age-associated decline of skeletal muscle satellite cell self-renewal and regenerative proliferation.

The best product contained 1.0 Wt% SWCNTs from (Mo2C)1-x–(TiC)x , x= 0.2 which was sintered at 1700°C, 70 MPa for 10 min, M0.8T0.2/ 1 Wt% SWCNTs exhibit a better density, highest hardness and good ductility. Relative densification was achieved 99.5 % from the theoretical and good mechanical properties like hardness and fracture toughness (KIC=5.6 Mpa m1/2) are improved. The results were confirmed using Raman scattering resonant spectroscopy.

Background The relationship between predictors and the variable of interest was estimated using a structural equation model which is used to predict latent variables. The main advantage of the SEM is the ability to estimate the direct and indirect pathways of the effect of the primary independent variable on the outcome, given sufficient sample sizes. Despite not directly modeling the mediated pathways, GLMMs excluding mediating variables performed well with respect to power, bias and coverage probability in modeling the total effect of the primary independent variables on the outcome. In longitudinal studies, data are collected from subjects at several time points. The main purpose of longitudinal analysis is to detecting the trends or trajectories of the variables of interest. Methods A longitudinal study was conducted on 792 adults living with HIV/AIDS who commenced HAART. Structural equation modeling was used to construct a model to detecting predictors of CD4 cell count change. The procedure was illustrated by applying it to longitudinal health-related quality-of-life data on HIV/AIDS patients, collected from September 2008 to August 2012 monthly for the first six months and quarterly for remaining study period. Results The result of current investigation indicates that CD4 cell count change was highly influenced by certain socio-demographic and clinical variables. Out of all the participants, 141 (82%) have been considered 100% adherent to antiretroviral therapy. Structural equation modeling has confirmed the direct effect that personality (decision-making and tolerance of frustration) has on motives to behave, or act accordingly, which was in turn directly related to medication adherence behaviors. In addition, these behaviors have had a direct and significant effect on viral load, as well as an indirect effect on CD4 cell count. The final model demonstrates the congruence between theory and data (x2/df. = 1.480, goodness of fit index = 0.97, adjusted goodness of fit index = 0.94, comparative fit index = 0.98, root mean square error of approximation = 0.05), accounting for 55.7% of the variance. Conclusions The results of this study support our theoretical model as a conceptual framework for the prediction of medication adherence behaviors in persons living with HIV/AIDS. Implications for designing, implementing, and evaluating intervention programs based on the model are to be discussed.

Introduction Acute leukaemia are the clonal and malignant proliferation of immature hematopoietic cells (blast), blocked in their differentiation process. There is an interaction between cancer cells and the clotting process. This could be the expression of Tissue Factor (TF) on the surface of tumor cells; or a lesion of the vascular endothelium and platelet activation. The result is an activation of clotting that can lead to disseminated Intravascular Coagulation (DIC). The objective of this study was to assess the risk of DIC occurring in patients with acute leukaemia. Methods This was a cross-sectional study for analytical purposes that took place on 40 frozen samples from the biobank of the haematology laboratory of Teaching Hospital Yopougon for which the diagnosis of acute leukaemia had been taken from myelogram. The myelogram results were accompanied by hemogram data. PTTa, QT, fibrinogen and D-Dimers were performed on these samples. The risk assessment of DIC occurred was determined on the recommendations of the International Society of Thrombosis and Hemostasis (ISTH). Results We noted a female predominance with a Sex Ratio (M / F) of 0.90. The average age of the patients was 38 years (± 23 years) with extremes ranging from 2 to 84 years. ALL represented 20 % of cases against 80 % for AMLs. Hemogram parameters were characterized by severe anaemia (Tx Hb < 6 g / dL) in 52.5 % of cases; hyperleukocytosis > 100.103 / mm3 in 35 % of cases; thrombocytopenia < 25.103 / mm3 in 40 % of case; and significant blood and spinal cord blastosis (> 80 %). The lengthening of the PTTa was observed in 50 % of cases, compared to 40% for the QT. Similarly, hyperfibrinemia was present in 65% of cases. D-Dimers were high in almost all subject (95 % of cases). According to the ISTH criteria, 17.5 % of subjects were at risk of developing a DIC. Conclusion The risk of occurrence of DIC is indeed present during acute leukaemia. The parameters of haemostasis are thus found to be crucial data in the follow-up assessment during the diagnosis of acute leukaemia.

Mental health and mental illness is a critical to a person’s overall health. In the United States alone, mental illness effects one in six adults. Furthermore, 40% of those individuals who die of suicide have been diagnosed with a mental health condition or illness. Yet, there is a paucity of research on innovative methods that help prevent suicide. The Contextual-Conceptual Therapy (CCT) approach introduces an innovative way to treat suicide by working to uncover the strengths of the suicidal person and addressing a person’s true self. The CCT approach was developed over the course of 25 years working with more than 16,000 suicidal patients in Seattle, Washington, and is tailored specifically for primary and secondary prevention of suicide. While there has been anecdotal evidence of the effectiveness of the CCT program, the program has yet to be formally evaluated. This qualitative research study aims to understand the impact the CCT approach has had on its clients. Eleven former CCT clients were recruited to participate in semi-structured interviews. Outcomes described by participants included an increase in curiosity and self-efficacy as a means through which to decrease suicide ideation and behavior, and proved to be incredibly powerful in changing long-term outcomes. This qualitative study is a first-step in providing critical insight on suicide prevention for wider dissemination. At a time when adverse mental health and illness is impacting the lives of millions of people, the CCT approach has the potential to address suicide, mental illness and mental health across diverse populations.

Cubic boron nitrid (cBN) bonded TiC and alloyed with single walled carbon nanotubes (SWCNTs or NC) ceramics matrix nanocomposites (CMNCs) tools were manufacturated by a field actived sparck plasma sintering processus (FASPS). The effects of cBN-TiC ratio, carbon nanotubes and optimisation of the sintering process on the microstructure, densification in addition mechanical and vibronic properties of NC-cBN-TiC nanocomposites were studied. The results showed that for the nanocomposite cBN-TiC vol. ratio of 8:2 with 0.1 wt% NC, it was found that microhardness incresses significantly with addition of carbon nanotubes exhibited the highest microhardness and fracture toughness. After sintering of the samples at 1800 °C, 10 mn, 75 MPa of cBN–TiC1-x, x=0.8 with and without addition of 0.1 wt% NC were characterized using field emission scanning electron microscopy (FESEM) and X-ray diffraction. The samples exhibited a dense polycrystalline structure. From the resonant Raman scattering we can locate the vibration frequency of the transformation cBN to hexagonal boron nitrid (hBN) and formation of secondary hard phase TiB2to consolid the (CMNCs) tools. The final product is hBN-TiC-TiB2-NC.The best product contained cBNx-TiC1-x (x=0.8)-0.1 wt % NC which was sintered at 1800 °C, 75 MPa for 10 mn. The Vickers hardness of cBN-TiC1-x (x=0.8) incresses with NC incorporation in the matrix The indentation fracture toughness was calculated to be 12.30 MPa m1/2 for cBNx-TiC1-x (x=0.8 -0.1 wt % NC ceramics matrix nanocomposite (CMNCs) tools with excellent wear resistant will be confirmed. The wear of cBN-TiC of the composites tools have shown that this is predominantly a chemical process involving the interaction of the tool with its environment and is restricted by the formation of protective layers on the exposed faces of the tool by the addition of carbon nanotubes (NC). The wear features of tools used in fine cutting tests under identical conditions will be compared and the results will be interpreted in terms of the existing models for the wear of cBN -based nanomaterials by the effects of the additives in the modified tools

Objective Exposure of dichlorvos-contaminated foods, water and environment can lead to decrease in proper liver function. Thus, Mimosa pudica(MP)is being investigated in the present study to determine its protective effect on dichlorvos induced hepatotoxity in Mice. Methods Fifty adult male BALB/c mice weighing between 20-30g were randomly assigned into 5 groups of 10 animals each (Groups A, B, C, D, and E). Group A as the control Group received normal feed, group B received 0.1 ml of MP, group C was given 40 g of 2.5% Dichlorvos (DDVP) for 28 days. While, group D were given 40 g of 2.5% DDVP with 0.1ml of MP and group E animals were given DDVP for half the period of administration, normal feed and 0.1ml MP for 14 days. Histological and biochemical preparations of the liver were processed and data were expressed as mean± SEM. Significant difference was set at p<0.05. Results ALT activity and the total protein level of the liver show no significant increase (P < 0.005) when compared with the control. AST and ALP activities were significantly increased in animals given DDVP with subsequent MP treatment when compared with the controls. Histological studies revealed distortion of normal hepatic histoarchitecture in DDVP group B and MP groups mitigated these changes in the treated groups. Conclusion Dichlorvos caused tissue distortion in the mice with prominent toxic effects on the liver while MP extract showed ameliorative effects on the liver that was exposed to DDVP

Since oxidative stress impairs the cardiovascular function, the hypothesis from the present study is that the treatment of paraquat-exposed adult Wistar rats with methanolic extract of Abelmoschus esculentusseed would reduce paraquat-induced cardiovascular damage. Thirty healthy female Wistar rats weighing 120-150 g were randomly assigned into 6 groups of 5 rats each (Groups A, B, C, D, E and F). Rats in groups A served as control and received normal saline while groups B, C, D, E and F received a single dose of paraquat (7mgkg-1i.p.). Rats in group B was sacrificed 24hours following paraquat administration while daily administration of 100 mg kg-1and 200 mg kg-1 of methanolic extract of Abelmoschus esculentusseed extract were given orally to groups C and D while group E received daily oral dose of Vitamin E at 100mgkg-1 and group F was left untreated. Histological and biochemical preparations of the heart was made and data were expressed as mean± SEM. Significant difference was set at p<0.05. Results showed no significance difference (p<0.05) in nitric oxide activity, Glutathione reductase activity, and troponin I activity across the paraquat-exposed groups when compared with control. Histological studies reveal distortion of normal cardiac histo-architecture in paraquat-exposed group B compared with control rats while Abelmoschus esculentus reversed these changes in other treated groups. The study concluded that paraquat caused significant distortion of the cardiac histo-architecture and methanolic extract of immature Abelmoschus esculentus seed had antioxidant and ameliorative effects similar to Vitamin E on paraquat-induced myocardial injury.

Rhinosinusitis is one of widely spread diseases in the region and the role of the anatomical variations in its pathogenesis remains unresolved. A retrospective study using CBCT scan was employed to locate and measure the diameter of 320 primary maxillary ostium (PMO) (n = 160 subjects) among the Malay and Chinese populations (Mongoloid race) in Malaysia. Image analysis was performed using the i-CAT Vision Software, employing the multiplanar reconstruction window in which axial, coronal and sagittal planes were visualized in 0.3 mm intervals. The mean diameter of the PMO was significantly larger in the Chinese than the Malay. Females had larger size than the male and bilateral asymmetry was noticed, where the right side PMO was larger than the left side (p < 0.05). In addition, PMO opened more in the posterior third position of the hiatus semilunaris (61.9%) than anterior and middle third. The PMO showed a statistically significant posteriorly placed position in the Chinese than the Malays and this was more evident in the right side PMO (p < 0.01). In conclusion, the PMO commonly opens in the posterior third of the hiatus semilunaris and its diameter is significantly greater in the Chinese female with evidence of bilateral asymmetry. Awareness the anatomical variation of the Ostium diameter and location among the Malay and Chinese populations potentially has important clinical effects during surgical procedures.

Obesity can be defined as a condition of abnormal or excess fat accumulation in adipose tissue, to the extent that health may be impaired. Fennel is one of the oldest spice plants which widely grows in arid and semi-arid and due to its economic importance and pharmaceutical industry usage. This plant has anti-inflammatory and analgesic effect and is effective in gastrointestinal disorder treatment. The aim of the present study was to evaluate the phytochemical characteristics and therapeutic properties of this medicinal plant. The current study demonstrates that the alteration induced by high fat diet causing changes in blood parameters. These changes are exhibited through a decrease in RBCs, Ht, Hb and platelet and these changes could be due to oxidative stress, which lead to lipid peroxidation in RBCs membranes, auto oxidation of hemoglobin. As regards the total WBCs, lymphocytes and monocytes showed marked decrease. While a distinct increase in the percentage of neutrophils and eosinophil. The present, demonstrates that rats treated with (fennel), (ator) and (fennel with ator) exposure provided significant protection to the altered hematological variables. The effect of the treatment with fennel and ator more effect than fennel only and ator only. The finding of this study indicates that the concentration of Malondialdehyde (MDA) and Myeloperoxidase (MPO) in liver homogenates of the fennel and ator group significant decrease than group (3) and group (4) and the obese group. There is a growing awareness that obesity is a prime risk factor for the development of dyslipidemia profile and that oxidative stress may play a role in various adverse effects of obesity.

Background The objective of this review is to unify the various genetic defects along with elaborating metabolic pathways in Familial Combined Hyperlipidemia(FCHL) and also to differentiate the phenotype of FCHL from metabolic syndrome. Methods PubMed and Cochrane’s library was searched for keyword “Familial combined hyperlipidemia” and latter with “Familial combined hyperlipidemia genes” to finally shortlist 23 articles. Further search with key words “molecular pathogenesis of familial combined hyperlipidemia” and “metabolic syndrome and familial combined hyperlipidemia” was carried out for finding molecular defects in FCHL, non-molecular findings distinguishing FCHL from metabolic syndrome and overlapping features between FCHL and metabolic syndrome. Results Major culprit regions identified included Chromosome-1q21-q24(USF1 and FOXA2) , Ch-11q (APOA5), Ch-16q24, Ch-20q12-q13.1, Ch.4q32.3 (rs6829588), and Ch-19q13.32 containing PVRL-2 gene (Also known as Nectin-2). The genetic and metabolic pathways linked to FCHL may involve: 1-Defective clearance of Apo-B containing lipoproteins, 2-Overproduction of Apo-B containing lipoprotein i.e., VLDL and 3-Adipose tissue dysfunction. FCHL phenotype showed close resemblance with metabolic syndrome clinical and biochemical features with slight differences. Conclusion The reviewed data suggested that FCHL phenotype is the resultant end outcome from multiple molecular defects and thus underlying genetic defect identification in the index case is important for personalized medicine and incoming gene therapy. Further research is warranted to explore specific genetic defects.

Background Hypothyroidism is a metabolic disorder affecting the functions of many tissues in the body including the testis. Testis is rich in the polyunsaturated fatty acids content and lacks strong intrinsic antioxidant system making it prone to such oxidative stress. L-carnitine (LC) regulates long chain fatty acids metabolism; and is considered a valuable antioxidant factor. Aim It was to evaluate the effect of hypothyroidism induced by propylthiouracil (PTU) on rats’ testes and the possible protective role of LC. Methods Forty-eight adult male albino rats were used in this work. The animals were divided into three groups with sixteen animals in each. Group 1 (Control): Animals were kept without medications. Group 2 (PTU-treated): was subjected to administration of PTU; while group 3 (PTU and LC) received both PTU and LC. By the end of the experiment “30 days”, blood samples were taken for hormonal assay; then animals were anaesthetized and sacrificed. Specimens were homogenized for biochemical analysis; epididymal content of each rat was obtained immediately for semen analysis. Testes’ specimens were harvested, prepared and examined by light microscope examination. Results Induced hypothyroidism was noticed to cause histopathological, morphometric and biochemical changes in rat’s testes. LC protected the testicular specimens against such changes; it also improved the seminal quality and quantity as well as testicular structure and biochemistry. Conclusion Hypothyroidism could result in hazards to the structure of testis. Fortunately co-administration of LC might reduce such hazards.

Objective Antisocial behavior (ASB) in children and youth is public health problem in Georgia. Nevertheless, there has been no systematic study the risk factors for ASB that could counteract on ASB development. To prevent ASB development and acceleration the understanding of biological (assessment of Brain morphology using MRI) and psychological (assessment using Freiburg Personality Inventory) risk factors is critical. This was the aim of this study. Method The children/youth with ASB tendency (AST) were identified by the Freiburg Personality Inventory (FBI). The biological and psychosocial factors contributing to AST were evaluated using a semi-structured clinical interview. Brain anatomy and morphology was studied using magnetic resonance imaging (MRI). Results Children/youth with AST had significant abnormalities in most axial elements of the DSM multi-axial system but not in brain anatomy measured by MRI. Conclusion Early identification of ASB tendencies and a provide correlationship between specific psychiatric, medical and family stress factors will likely reduce the number of children/youth with ASB and will promote their integration into society.

Objectives Death is the only definitive phenomenon in life, and everyone is sure that it will happen in the future. Based on the philosophical perspective, the concept of death differs in different cultures. The purpose of this study was “explaining the difference between the concept of death from the perspective of theology and empirical science”. Methods In this qualitative evolutionary study, a targeted review was conducted to answer the question “what is the difference between the concept of death from the perspective of theology and empirical science?” Articles published between 1990 and 2018 were extracted from the PubMed, science direct, google scholar, SID, and Cochrane databases. At the same time, Islamic religious evidence (Quran and Hadiths) was investigated for understanding the concept of the death in Islam. The “Shia Seminary” research methodology was used to avoid interpretations of the Quran verses and to ensure the authenticity of the Hadiths. Findings Empirical sciences consider death as a biological phenomenon, which results from irreversible damage to cerebral hemispheres and brain stem (brain death) that causes grief process, fear, anxiety, and sadness. From the perspective of Islam, death is an existential phenomenon, the transfer of the soul from one world to another. Death is the complete reception of the soul from the body by the angels and the beginning of another life, in the "world of grief. Conclusion Given that in Islam, death does not mean destruction. It is imperative that the spiritual counselors teach the patient and the family about the life after death and the blessings of paradise. In pastoral care at the end of life, reducing patients’ anxiety and fear of death, with hope in God's mercy is necessary.

Background This study aim to assess the factors affecting uptake of cervical cancer screening programmes among female staff of the University College Hospital (UCH), Ibadan in 2014. Method A descriptive cross-sectional study involving 375 participants selected using a stratified random sampling technique with proportional allocation to population size and interviewed using a pre-tested self-administered semi-structured questionnaire. Information on their basic knowledge on cervical cancer were scored to determine good knowledge. Patients’ attitudes toward cervical cancer screening as well as factors affecting uptake were also assessed. Data analysis was done in 2014 using descriptive statistics while screening uptake predictors were determined using logistic regression at p ≤0.05. Results Completed questionnaires were returned by 360 respondents; 13.3% were clinical while 86.7% were non-clinical staff of age range 20 to 58 years (38.2±0.42 years). Majority of the respondents, (95.5%), had heard about cervical cancer with 61.9% having “good knowledge”, but only few (34.2%) had been screened. Averagely, 47.5% displayed positive attitude to cervical cancer screening with Pap smear being the most reported screening procedure. The common barriers to screening uptaking include indecision, inadequate information and feeling of good health. Others were staff hostility, lack of privacy, and cost. Using logistic Regression at p ≤0.05, females with negative attitude and those with children were less likely to uptake cervical cancer screening services. Conclusion The knowledge-uptake gaps of cervical cancer screenings were high as revealed in this study. Therefore, there is a need to further educate eligible women on uptake of cervical cancer screening.

An 81-year-old male presented to the Emergency Department with urinary retention, subsequent to passing blood clots. A three-way catheter was inserted for continuous bladder irrigation. 48 hours later he deteriorated, with worsening tachypnea and hypoxaemia. Clinical examination and chest x-ray suggested pulmonary odema, managed with intravenous furosemide, and non-invasive ventilation. His irrigation circuit-chart showed he had received 10 litres Normal Saline via the afferent limb, but only 3 litres recorded at the efferent limb. It was suspected the catheter was adjacent to a vascular-cystic interface, however an urgent contrast CT revealed the irrigating catheter perforating the bladder, being situated in the abdominal cavity (see 3 images). His arterial blood-gas analysis demonstrated the expected normal anion-gap academia, however his Strong Ion Difference calculations, sodium-chloride difference of 13 and a normal albumin level, perfectly demonstrated the expected calculated BE of -13. The catheter was withdrawn, and the patient made a full recovery.

Over last few decades, acreage of total fallow lands (Kharif and Rabi seasons) in India has remained almost unchanged around 25Mha. The acreage of Kharif (summer) and Rabi (winter) Fallows in Madhya Pradesh (MP) are 1.98Mha and 5.51Mha, respectively. In the semi-arid agroclimatic zones of the states, Fallow-Wheat/Gram/Indian-Mustard cropping systems are practiced. After harvest of Kharif rice, kodo-kutki, maize or sorghum, farmers generally practice post-rainy season Rabi fallows in the sub-humid regions, south of Narmada River. Kharif fallowing is largely the result of the inability of the farmers to make planting dates independent of monsoon forecasts, and make efficient use of rain water. It appears that factors responsible for Kharif and Rabi fallows are distinctly different and a general consequence of distinctly different soil moisture regimes prevailing in the two crop seasons. Kharif and Rabi fallows have two distinct resource management domains. Whereas, Kharif fallows can be tackled with “PMP-dry seeding” agronomy, production constraints of Rabi fallows can be substantively tackled by shifting from tilled to zero-till agriculture with residue management to make efficient use of the conserved rain water. Some irrigation support will prove useful to tackle mid-season droughts in both situations. Conservation agricultural practices can significantly improve and stabilize crop yields in black soils and other associated soils of in the semi-arid tropics region of the Central India.

We analyze the effects of the ethnomycological knowledge depending on the age range of its users and how far their homes are from the forest areas. As a study model, the traditional mycological knowledge of San Pedro Tlalcuapan SPT, in Central Mexico was used. During 2017, 135 semi-structured interviews were conducted with people of three age ranges and living in three areas of the community located at different distances from the forest. Data was analyzed using descriptive statistics and analyses of non-metric multidimensional scaling, which were then applied to calculate two indices. The effect of age and origin of the individuals on bio-cultural relevance was assessed using multiple linear regression models.Fifty species of edible wild mushrooms were registered, those mentioned most often were of the Russuladelica complex., Amanita basii and Boletus aff. edulis. Ninety-five percent of the people interviewed consumed wild mushrooms on average two times a week, while 57% collected them. Wild mushrooms are mainly recognized for their food and ecological importance. Ordination and regression analyses show that people closest to the forest, as well as older people, are able to identify more of the wild mushrooms and have greater bio-cultural mushroom awareness. Results show that there is a risk that traditional knowledge about wild mushrooms will disappear, since it is only popular in a part of the community and only at some age ranges, indicating that there is a disconnect in the transfer of knowledge.

Cancer is the leading cause of death worldwide, and there is a constant need for new treatment strategies. Sesquiterpene lactones containing a 3-methylenedihydrofuran-2(3H)-one (or α-methylene-γ-lactone) moiety, for example damsin (1), are Michael acceptors that affect biological processes such as cell proliferation, death/apoptosis, and cell migration, by interfering with cell signalling pathways. Although the reactivity of the α-methylene-γ-lactone moiety is important for these effects, the Michael addition is reversible and it can be assumed that also other parts of the molecules will moderate any given biological activity. In this investigation, the cytotoxicity of 23 -methylene--lactones towards normal breast epithelial MCF-10A cells as well as breast cancer JIMT-1 cells is compared. Most of the investigated compounds are semisynthetic derivatives prepared by the condensation of the natural product damsin (1) with aldehydes. The two cell lines were treated with various concentrations of the compounds in dose response assays, and the 50 % inhibitory concentration (IC50) was determined from dose response curves. The IC50 values were found to depend strongly on the overall structure. The ratio between the IC50 values for MCF-10A and JIMT-1 cells, as a measure for the selectivity of a compound to kill cancer cells, was calculated, and found to vary between just over 1 to more than 10. The most potent derivatives formed from the condensation of 1 with aromatic aldehydes towards JIMT-1 cells are 3a and 3i, both with ratios between the IC50 values for MCF-10A and JIMT-1 cells close to 5. Also some aldol condensation products with acyclic aldehydes, i.e. 3r and 3u, were equally potent, and the latter showed the highest selectivity (ratio > 10). Structure-activity relationships that may explain the observed differences in potency and selectivity are discussed.

While; the respondents from Faculties of Agriculture, assessed the Graduated for practical skills, teaching ability, skills of writing scientific papers, participation in workshops and seminars as good (93.3%), very good (6.7%), fair (6.7) and very good (33.3%), respectively. The Graduates’ quality is below the expectations. Based on the above findings, the study recommends the review of the whole educational system, Faculties of Agriculture to include the concepts of sustainable agriculture in their curriculum and give high consideration to practical part. In the same context, further study is recommended including the whole Country.

Background Research has demonstrated that partners living alongside veterans with mental health difficulties are at high risk of developing mental health difficulties themselves and secondary trauma. A variety of interventions have been developed to support partners. Research to date has relied on quantitative methodologies to evaluate the efficacy of such interventions with less emphasis on learning about the experiences of individuals on the courses. Objective The aim of this qualitative paper was to understand the experiences of partners who engaged in a five-week structured support intervention, ‘The Together Programme’ (TTP) which had been piloted across UK cities. This programme involved tailored psycho educational materials adapted to the needs of veteran’s partners living alongside PTSD. Further the potential mechanisms of change for participants engaged with the programme were explored as well as the impact of treatment on their relationships. Methods Eight female partners were recruited from an original sample of 57 partners who were intimate relationships with treatment seeking veterans with mental health difficulties. These participants had completed TTP. Qualitative data was collected using a semi structured interview and explored using Interpretative Phenomenological Analysis. Results Three key themes emerged from the data, these were self-growth, changing role in relationships and connecting with others. The themes included several sub themes. Self-growth sub-themes were mastering the ‘inner judge’, ‘confidence in ability to cope’ and ‘taking care of my needs’. Changing role in relationship sub-themes were ‘acceptance and understanding’ and ‘improved communication in relationship’. Connecting with others was described by the sub-themes of ‘knowing I am not alone’, ‘peer support’ and ‘hope’. Conclusions This study suggeststhere were three key areas where thestructured evidence-based support programme had an impact on participants experiences. These were factors that helped participants to normalise their experiences and increase participants understanding and interpersonal skills that promote changes in relationship functioning with the veteran.

Distant metastases generally indicate disseminated disease and the standard treatment for these patients is palliative chemotherapy. Retrospective series showed that selected patients with metastatic lung cancer and a solitary extrathoracic disease could be effectively treated with curative intention by resection of both primary tumor and the single site of metastatic disease. According to current data, adrenalectomy might be considered as an alternative option for patients with isolated adrenal metastases. Significant morbidity and mortality may be happened by these procedures, and a cautious analysis of pros and cons should be discussed with the patient. We present a review of the literature and updated recommendations focusing lung cancer with solitary adrenal metastasis.

Several studies show that policies to improve maternal and infant health must be contextualised within broader questions and commitments concerning women’s empowerment. There are, however, two-way linkages between women’s empowerment and reproductive services. Certain institutional approaches that support women’s reproductive health can themselves be experienced as empowering whereas others, however well-meaning, can be experienced as disempowering, undermining health and broader goals. It is thus important to discern and support those elements of reproductive services that might have empowerment outcomes, and to avoid others that undermine them. This paper is premised on the hypothesis that approaches to reproductive health that are rooted in women’s life worlds, that support women’s social networks and which enhance women’s confidence and control will have very different empowerment effect from those that subordinate women and their networks to external expertise and (often male) authority and undermine women’s preferences or autonomy. We (a) conduct an audit of positive practices concerning maternal and child health and (b) examine how current support to maternal and infant health articulates with this. Analysis seeks to reposition indigenous knowledge, community wisdom and their secular practices in a way that promotes better health provision that is integrated with these existing practices and that is empowering.

Excessive variability in behavioral performance and neuronal activation is a common finding in studies of schizophrenia. Recent evidence suggests that this may be due to an imbalance in the ratio of excitation to inhibition in brain function, or E/I imbalance. We used computational modeling of visual system activity to determine whether different potential causes of E/I imbalance would generate effects resembling those reported in schizophrenia. Three major findings emerged. First, reductions in retinal and lateral geniculate nucleus signaling initially led to increases in firing rate variability within the context of reduced V1 activation; however, with prolonged adaptation to weakened sensory signaling, compensatory hyper-activation in V1 neurons occurred, but variability was no longer increased. Second, direct increases in V1 excitation, or decreases in inhibition, led to the highest levels of initial activation but not variability; however, with prolonged inhibitory adaptation to increased excitation, overall activity was no longer elevated, but an increase in firing rate variability was observed. Third, the greatest fluctuation in firing rate variability, in response to the same stimulus across increasing contrast levels, was observed with reductions in sensory signaling, but only immediately after model perturbations; with prolonged adaption, the largest fluctuations were associated with increased excitation or reduced inhibition within V1. Implication of these findings are that schizophrenia-related increases in neuronal response variability may arise from at least two sources: 1) weakened sensory signaling and its associated low signal-to-noise ratio; and 2) compensatory but incomplete inhibitory responses to continuous increases in cortical excitation.

Purpose: The perception of time and its measurements depend on subjective constructs that vary according to changes in health. The evidence has shown that cancer diagnosis induces new relationships with time in patients and caregivers. The purpose of this study was to propose a multifaceted view about time perception referred by caregivers of cancer survivors. Methods: This study used a qualitative phenomenological methodology including semi-structured interviews with caregivers of cancer survivors. Transcripts of the interviews were analyzed using an approach for intertextual analysis, taking as reference the book "Einstein's dreams". Results: The analysis of transcripts shows changes caregivers’ time perception. Participants were grouped into three essential moments related to each stage of the disease. The variations found in the perception of time in caregivers can be explained by common physiological and behavioral responses associated with the diagnosis of a chronic disease (i.e. stress, anxiety, fear, unhappiness, and sadness), which can be modified in the course of the disease. Conclusions: We propose that a holistic approach to patient and caregiver care should include management of time perception, thus establishing interventions that facilitate a change in the experience of time perception into a more pleasant experience after a cancer diagnosis. The above may result in increased quality of patient care and possibly increased quality of life of caregivers.
