This study was conducted to evaluate the effect of the substitution of fishmeal by Lima bean flouron the growth performance, survival rate and feed cost of Clariasgariepinusbetween March and May 2018 within the AIO ICG of the Batié District. It also aimed to contribute to the development of alternative sources of animal protein on a global scale. For this purpose, 300 fry of Clariasgariepinuswith an average weight of 3 ± 1.41g were divided into five batches and fed three times a day with rations corresponding to 5% of their ichthyobiomass. The rations R0, R25 R50, R75 and R100 respectively corresponded to the substitution rates of 0, 25, 50, 75 and 100% of fish meal by that of Lima bean. The physic-chemical characteristics of the water (pH, temperature, dissolved oxygen, nitrites and nitrates) were measured daily. The following results were obtained: The highest weight gains were obtained with the rations R25 (20.56 ± 0.40 g), R50 (20.64 ± 0.32 g), R75 (20.98 ± 0.46 g) and the lowest with the rations of R100 (16.21 ± 0.28 g). The highest average daily gain were 0.36 ± 0.02 g; 0.37 ± 0.01 g ; 0.38 ± 0.01 g respectively for the R0, R50 and R75 rations and the lowest with R100 (0.29 ± 0.01 g). The highest value of the specific growth rate (2.47 ± 0.07%) was obtained with the ration R0 and the lowest (1.61%) with the ration R100. The consumption index reached its highest and lowest values with the rations R100 (4.74 ± 0.42) and R50 (3.57 ± 0.43) respectively, compared to the value of the ration R0 (3.31 ± 0.37) for this parameter. Concerning the condition factor K, the highest value was recorded with the R50 diet (1.11 ± 0.49) while the lowest value was obtained with the R75 diet (0.95 ± 0.45). The cost of producing one kilogram of food was higher with the R25 ration (504.59 FCFA) and lower with the R100 ration (443.20 FCFA). Our results revealed that incorporating 75% Lima bean flour into the feed increases the growth performance of Clariasgariepinus fry and reduces the cost of food production.

Purpose of Study To study reparative osteogenesis and tissue integration characteristics for implanting three-dimensional mesh structures of titanium nickelide into a bone cavitary defect. Material and Methods The authors modeled cavitary defects of femoral metaphysis experimentally in Wistar rats divided into an experimental group and control one. The study duration was 60 days in total. The methods of radiography, those of light and electron microscopy, X-ray electron probe microanalysis used. Results Under implantation the defect was filled with cancellous bone the volumetric density of which more than 1,5-fold exceeded control values (р < 0.001). The implant had biocompatibility, osteoconductive and osteoinductive properties, it stopped inflammatory processes. The membrane protective barrier which prevented connective tissue sprouting was formed on the implant surface in the defect periosteal zone. The osteointegrative junction was formed being persisted up to the end of the experiment. Reparative osteogenesis was performed by direct intramembranous and apposition type. Conclusion The implant of three-dimensional mesh titaium-nickelide structures has marked osteoplastic properties, and it can be successfully used in orthopedic surgery.

We report a twin gestation with one fetus afflicted by a left sided Extra-Lobar Sequestration (ELS) in a morbidly obese mother. The ELS was complicated by a left pleural effusion in the second trimester unresponsive to maternal steroid administration. We discuss the need for repeat shunt placement, in the setting of maternal morbid obesity and twin gestation. Shunt replacement was necessary secondary to dislodgement. Delivery at 34 weeks gestation was followed by successful surgical removal of the ELS. At one year follow up the infant has complete expansion of the left lung with no morbidity.

Purpose: The aim of the study was to analyze the spatial relationship between the sinus floor and the alveolar bone of maxillary premolars and molars in order to assess the amount of basal bone available for immediate extraction placement of endosseous implants. Materials and Methods: All the cone-beam computerized tomographic (CBCT) scans taken over a three-year period at four centers were identified. The subsinus bone height (SBH) was evaluated by measuring the distance between the sinus floor and the first and second premolar root apexes. The interradicular septum bone height (ISBH) of all the first and second molars was also measured, and the presence or absence of sinus-floor invagination between the molar roots was recorded. Results: Five hundred twenty-six (526) CBCT scans of fully or partially dentate maxillary arches were examined. The root apex was inside the sinus of 1.8% of all the first premolars. It approximated the sinus floor of 5.3% of them, and the distance between the two points was between 1 and 3mm of 20%, between 3 and 7mm for 34.1%, and more than 7mm for 34.1%. For the second premolars, the findings were 13.5% (inside the sinus), 10.5% (touching the sinus), 32.8% (1-3mm of distance) 28% (3-7 mm), and 15.2% (more than 7mm). Root invagination was noted in 50.2% of the first molars and 43.1% of the second molars, with the ISBHs ranging from 13.4% to 56.9%. Conclusion: Radiological evaluation is essential to determining whether implants should be placed immediately after extraction of maxillary premolars and molars.

This narrative literature review investigates the clinical feasibility of maxillary sinus lift using the lateral window (or traumatic) technique, employing a grafting material composed of hydroxyapatite associated with beta-tricalcium phosphate. The study is based on the premise that bone resorption and sinus pneumatization—common in edentulous posterior maxillae—pose a challenge to achieving primary stability during dental implant placement. Given the limitation imposed by reduced residual bone height, bone-grafting surgical techniques become necessary to enable implant-supported rehabilitation. The objective of this work is to analyze, through a literature review, the efficacy of combining synthetic biomaterials as an alternative to autogenous bone grafts, which are considered the gold standard in implant dentistry. A bibliographic search was conducted in the PubMed and LILACS databases and through the VHL portal, prioritizing articles addressing the biological properties of alloplastic grafts, the indications of the lateral window technique, and the clinical success rates of implants placed in previously grafted areas using such materials. The findings demonstrated that hydroxyapatite associated with beta-tricalcium phosphate exhibits favorable osteoconductive characteristics, such as adequate porosity and gradual resorption, while allowing the formation of viable bone within a clinically acceptable timeframe. The combination of these materials eliminates the need for a second surgical site, reduces morbidity, and maintains treatment predictability. It is concluded that the lateral window technique associated with synthetic biomaterials is a safe and effective alternative for patients with maxillary bone atrophy, capable of promoting suitable bone beds for dental implant placement and stabilization, with lower surgical risk and satisfactory clinical outcomes.

The rising costs of conventional poultry feed ingredients, such as soybean, maize, and fish meal, have prompted the search for more affordable and sustainable alternatives in poultry production. This study investigates the use of phytase-supplemented Palm Kernel Cake (PKC) as a replacement for soybean meal to improve feed efficiency, nutrient absorption, and growth performance in poultry. White Leghorn layers, Rhode Island Red layers, broilers, and cockerels were fed three different feed formulations: conventional feed (CF), Moderate PKC with Phytase (MPP), and High PKC with Phytase (HPP). The results showed that PKC-based diets significantly reduced feed costs while maintaining satisfactory growth, although CF led to higher body weight gain and feed efficiency. The MPP formulation struck an optimal balance between cost savings and nutritional quality, making it a viable option for layers and cockerels, while CF remained the most effective for broilers. While the HPP formulation resulted in lower feed costs, it compromised weight gain and overall profitability. These findings highlight the potential of phytase-enhanced PKC as a sustainable, cost-effective alternative to conventional feed, particularly in regions with high feed costs. However, the study emphasizes the importance of balancing cost reductions with feed quality to maximize profitability. Future research should focus on optimizing PKC inclusion levels and exploring additional enzyme supplements to further enhance feed efficiency and support sustainable poultry farming practices. This study provides valuable insights into how strategic feed formulation can support both economic and production goals in the poultry industry.

Background In adult males, non-communicating hydroceles are non fluctuant scrotal swellings that are formed when there is an imbalance of fluid secretion and absorption between the parietal and visceral layers of the tunica vaginalis. Giant hydroceles are a rare manifestation and have previously been classified as hydroceles that drain more than 1000 mL of fluid. In this report, we describe a case of a giant hydrocele requiring surgical management and highlight a review of the literature. Case Presentation A 34-year-old male presented with complaints of large right-sided scrotal swelling, accompanied by scrotal discomfort. Ultrasound of the right testicle revealed a large hypoechoic space with a complex collection and posterior displacement of the testicle, indicating a possible hydrocele. The patient was taken to the operating room for a right hydrocelectomy. Approximately 2 liters of fluid were drained from the sac. Discussion Hydroceles are defined as straw-colored fluid collections within the parietal and visceral layers of the tunica vaginalis. Giant hydroceles, defined as fluid collections within the tunica vaginalis exceeding 1000 mL, are rare and the management of such cases is sparsely documented in the literature. While most asymptomatic fluid collections resolve spontaneously, larger collections with inflammatory changes within the testicular wall may require surgical intervention, either laparoscopic or open.

This prospective randomized double-blinded multicentric study aimed to assess the efficacy of a new nutraceutical in controlling itch and skin lesions caused by flea allergy dermatitis (FAD) and compare it with another oral product of proven efficacy. Forty-three dogs, of different age, breed and sex, with FAD were included and divided into two groups: 24 received product A and 19 product B. Both groups received the same antiparasitic treatment. A modified canine atopic lesion index (mCADLI) and pruritus visual analogic scale (pVAS) were recorded at days 0, 30 and 60. pVAS was evaluated both by the examining veterinarian (vpVAS) and the owner (opVAS). Results obtained were compared between the two groups at each time point. In both groups of dogs, a significant decrease of mCADLI, vpVAS and opVAS at day 30 and 60, compared to day 0, was observed. At baseline, the mCADLI scores of Group B were significantly higher than Group A (95% CI: -4.0 to 0.0, p < 0.05), with no differences at D30 and D60 (not significant, p > 0.05). In Group B, significantly lower values of vpVAS were observed at D30 compared to Group A (95% CI: -2.5 to 0.0, p < 0.05), but not at D60 (not significant, p > 0.05). The median values of pVAS in Group B were lower compared to Group A at both D30 (95% CI: -2.5 to 0.4, p < 0.01) and D60 (95% CI: -3.0 to 0.3, p < 0.05). Both nutraceuticals can be useful to control discomfort, skin lesions and pruritus due to flea allergy dermatitis and can be a valuable replacement for antipruritic drugs antihistamines, steroids or Il-31 inhibitors.

Introduction Rheumatic heart disease is mostly common in low-income or developing parts of the world, such as Sub-Saharan Africa, with a high morbidity and mortality rate. There are few data that are available in Chad on rheumatic heart disease. Our objective was to study the clinical, echocardiographic, therapeutic, and progressive aspects of rheumatic heart disease at the Renaissance University Hospital Center and the National Reference Teaching Hospital in N’Djamena, Chad. Patient and methods This was a prospective, multicenter and observational cohort study, covering a consecutive series of patients consulted and/or hospitalized for rheumatic heart disease, documented by an echocardiogram from January 2015 to January 2021. Results Among the 4456 patients consulted and/or hospitalized, 398 cases of rheumatic heart disease (8.9%) were collected, and 364 patients had met the inclusion criteria. The mean age was 31.2 ± 14.4 years, and 193 patients (53%) were female. On admission, heart failure was present in 214 patients (58.8%), ischemic stroke in 10 patients (2.7%) and supraventricular arrhythmias such as atrial fibrillation in 94 patients (25.8%) and atrial flutter in 6 patients (1.6%). Mitral regurgitation was observed in 49.7% (n=181) of cases, aortic regurgitation in 33.2% (n=121), mitral stenosis in 31.3% (n=114), and aortic stenosis in 7.7% (n=28). At least two valvular disorders were combined in 48.4% of cases. A surgical intervention such as a heart valve replacement and/or valvuloplasty was performed in 80 patients (22.2%). At least one rehospitalization was noted in 56.9% of patients. Forty-two of the 150 patients free of heart failure at inclusion (28%) had experienced the first episode of decompensated heart failure during follow-up. On the other hand, in 119 patients (55.6%), it was the second episode of decompensated heart failure. Other progressive complications included atrial fibrillation (13.8%), thromboembolic complications (6.3%), infective endocarditis (6.0%) and prosthetic valve dysfunction (1.4%). Altogether, the mortality rate was 10.4%. It was 9.9% in non-operated patients compared to 12.5% in operated patients (p=0.49). Conclusion The present study shows that morbidity and mortality of rheumatic heart disease remain high in our context and often affect children, young adults, and women. Treatment is essentially based on cardiac surgery which is not available in Chad.

This study was conducted to evaluate the effect of socked pigeon pea seed meal on Growth and Food Utilization Efficiency of Nile tilapia (Oreochromis niloticus) fingerlings. 120 fish the weight and length average (3.4±0.04g and 3.2±0.00cm) were randomly distributed in 12 plastic Tanks (Aquarium) 36L according to the complete randomization, allocated to a represent four treatments (T0, T1, T2, and T3) of Nile tilapia (Oreochromis niloticus) fingerlings. four feeds were prepared in pellet form which consisted of 0%, 25%, 50% and 75% pigeon pea seed meal as replacement of fish meal. All diets contents 30% protein. Nile tilapia (Oreochromis niloticus) fingerlings were fed at the rate of 5% of their body weight. The result showed significant variation (P < 0.05) in final body weight, weight gain (WG), daily weight growth (DWG), Specific Growth Rate (SGR), and Food Conversion Ratio (FCR) among treatments. But, high SGR in T0 (control) and the best FCR were obtained at T 0% pigeon pea seed meal. Over all, best growth performance was observed in fish fed diet T1 (25%). The best performing fish’s final weight, DWG, SGR and FCR were 9.46±0.33g, 0.13±0.01g/day, 2.93±0.73% /day and 1.49±0.30 respectively. On the other hand, there was high significant variation (P < 0.05) in survival rate were obtained at T2 (50%). this study recommend that a diet containing 25% Pigeon pea seed meal for juvenile Nile tilapia is optimum in terms of growth performance and profitability, and does not impact water quality and plankton abundance in plastic Tanks (Aquarium) culture system.

In the present document, the dynamic analysis of isotropic materials applied to the laminated composite beam has been studied to improve the simplification of the homogenization process of heterogeneous composite materials.12 This study is based on the conventional stratified theory of Von Karman's formulation and the kinetic energy of Euler Bernoulli developed through displacement relationships. The model used in this study to explain the problem of non-linear geometry in the free vibration applied of laminated beam is based on the Hamilton's principle for solving the motion equation and determining the frequency of the reaction of the rolled beam. The numerical of the symmetric an asymmetric material gives a good idea of the behaviour of the orthotropic materials, and to minimize the problem of many areas used these materials such as: dental medicine, aeronautical, aerospace, because they have a good strength, high rigidity.23 The comparison between the different lay up may give greater importance to this study and open the search to simplify the problem of non linear geometry and give a good result about the older other published. For instance the application of medicine,the researcher has to decode the compatibility of the human body with new materials,and to minimize the problem of deterioration,The comparison with different lay up give more interesting by the mechanical engineering and the researcher's to give the solution of no linear problem and optimize the composite material’s to adaptation with problem study.4

Tactile information plays an important role in human manipulation of objects; however, prosthetic limb placement or teleoperation requires the manipulation of alternative bodies in the absence of tactile sensations. To provide an alternative to tactile sensation, this study proposes and assesses a continuous feedback scheme with temporally coded vibration. This scheme was designed to provide discrete intended tactile information in response to changing object-controlled situations by repetitively presenting time-coded vibration patterns. The effects of the proposed scheme on an object with acatch-and-hold task in virtual reality were confirmed. Compared to the control feedback scheme that provides vibration only when the balance of the virtual grip force and object position is changed, the proposed feedback scheme has a better effect in terms of the success rate of holding on to the object with an appropriate holding force during the task. The effect is larger, especially in the invisible task condition, suggesting that the increased amount of information with coded vibration patterns can be used without any special training, especially without visual information. Considering the existing studies that show the effect of a feedback scheme in response to motion events, the continuous feedback scheme proposed in this study may be more suitable for movements that require sequential coordination and passive responses than stimulation methods based on motion events. This feedback scheme has potential applications not only in tele-technology but also in healthcare, such as rehabilitation.

Contact intensity is a significant factor in immoveable implant restorations. This study visually compares the use of four occlusal contact indicators one of which measures contact intensity and surface area in a single subject. The need for an occlusal contact indicator that can be used with fixed implant restorations is examined. Three contact indicators used in practice are visually compared to a novel system where pressure sensitive information and surface area can be evaluated numerically and stored. Findings suggest that intensity and surface area should be measured upon implant placement. Limitations of this observational study are discussed. Directions for future research and more systematic study are offered

Steroid cell tumors of the ovary are particularly rare, secreting sex hormones, characterized by steroid cell proliferation and represent only 0.1% of all ovarian tumors. They are classified into three subtypes according to their cell of origin: stromal luteoma, Leydig cell tumors and a third subtype of unknown lineage corresponds to a not specified steroid cell tumor (SCT-NOS). This third subtype accounts for 60% of steroid cell tumors. The clinical manifestations of SCT-NOS can take many forms, including pain, abdominal distension, but perhaps the most visible presentations are those related to hormonal activity and virilization of the tumor. We present a rare case of a 48-year-old woman with vaginal bleeding and a history of trunk obesity, hirsutism for 2 years and hypothyroidism with hormone replacement therapy. Clinical examination revealed a characteristic of obesity, virilization. Serum testosterone was 3.62 µg / L and CA-125 was 40.67. Magnetic resonance imaging identified a left ovarian solid mass and histopathology confirmed a steroid cell tumor not specific. The patient underwent exploratory laparotomy and left salpingoophorectomy. Macroscopically, the mass is well circumscribed, solid, homogeneous and yellowish. Microscopically, the tumor is mainly composed of eosinophilic or vacuolar granular cytoplasm. Immunohistochemistry showed that the tumor cells were strongly positive for inhibin. The postoperative period was uneventful. Through this rare observation, we will discuss the aspects that characterize this type of tumor and present some guidelines to be used in the differential diagnosis, as well as the difficulties encountered in the clinical, radiological and therapeutic fields.

Upon considering the anticancer effects of larger oligomeric proanthocyanidins and observing various papers reporting the high resolution mass spectroscopy of the oligomeric proanthocyanidins, it is determined that the unusual 13C enrichment in some plant oligomeric proanthocyanidins may be responsible for the anticancer activities of these food products. Such correlation of the 13C in the oligomeric proanthocyanidins also correlate with their scavenging of free-radicals, anti-virial and anti-bacterial properties. Proanthocyanidins in grape seeds are observed to have high enrichment in heavy isotopes of 2H, 13C, 15N and/or 17O. Mass analysis of DNA from human cancer cells are compared to normal human cells and cancer cells show bond specific enrichment of heavy isotopes in nucleotides G, A, T and C. On such basis, this study suggests possible stronger interactions of proanthocyanidins with DNA in cancer verses DNA in normal cells due to heavy isotope bond specific enrichments in both proanthocyanidins and the cancer DNA. Such 13C interactions from oligomeric proanthocyanidins with nucleic acids and proteins involved in replications, transcriptions and translations in cancer cells for interacting and chemically altering anabolism and cell division of the cancer cells are consistent with the author’s mechanism for normal cell to cancer cell transformations via possible replacements of primordial 1H, 12C, 14N, 16O, and 24Mg isotopes by nonprimordial 2H, 13C, 15N, and 17O and 25Mg isotopes in the proteins and nucleic acids. Such is also consistent with the proposed treatment for cancer by the author by use of foods containing proteins, nucleic acids, carbohydrates and/or drug molecules enriched with the nonprimordial isotopes of 2H, 13C, 15N, and 17O and 25Mg.

Older adults suffering from chronically painful disabling osteoarthritis of one or more joints such as the hip joint continue to experience multiple health issues, commonly progressive debility, and excess disability. This mini review strove to examine current perspectives in the realm of hip joint osteoarthritis, a widespread disabling disease affecting many older adults in the face of the possible repercussions of the multiple COVID-19 restrictions in response to the SARS-CoV-2 pandemic that emerged in late 2019, along with the persistence of multiple evolving COVID-19 variants that remain lethal to many older adults, especially among the older chronically impaired population. Using multiple data bases, results reveal that very little progress has been made in recent times to mitigate hip osteoarthritis, along with very few innovative treatment approaches when severe, other than surgery and medication. Moreover, a multitude of non-pharmacologic approaches have not reduced numbers of cases requiring surgery to any extent, even when employed. In addition, outcomes of hip joint replacement surgery, and other treatments for ameliorating unrelenting pain remain largely suboptimal, especially where those undergoing surgery may now be more impaired than in pre pandemic times, and where high rates of opioid related deaths prevail in this regard. As such, it is concluded that whether in the community or being treated in hospital, exposure to COVID-19 remains risky especially in cases who are now weaker and frail, plus suffering from excess chronic disease manifestations, thus warranting more attention and protection of this high risk group, plus insightful preventive efforts to avert multiple interacting COVID-19 effects in the realm of osteoarthritis suffering, especially where patients are willing to risk infection by undergoing surgery.

Purpose Is it safe to excise only the external portion of the pacemaker wires? This presentation aims to find out the proper way to manage pacing wires postoperatively. Methods We report 5-cases of sub-xiphoid abscesses and sinuses after valve surgery. Each case presented with a recurrent abscess that opens and drains its contents through a sinus around the lower-most portion of the xiphoid process. The duration between open heart surgery and evolution of these abscesses varied between 18 and 60 months. Valve surgeries were mitral and/or aortic valve replacement. Surgeons usually insert pacemaker wires to control any persistent post-operative arrhythmias that can affect hemodynamic circulation. On the day of discharge, some surgeons (not in our center) usually excise the pacemaker wires. Results The remaining intra-thoracic portions underwent some degree of corrosion that caused a state of chronic inflammation, sinus track formation and abscess evolution. This indicated radiological examination and surgical exploration to extract these foreign bodies. These 5 cases were diagnosed and operated upon between 15th January 2022 and 1st March2022, all at Abo-Khalifa Emergency Hospital-Ismailia, Egypt. Conclusions This confirms the significance of total withdrawal of the external pacemaker wires. Surgeons should not apply tight sutures at the site of insertion of the wires.

Medical education has been extraordinarily disrupted during the COVID-19 era worldwide. The pandemic limited routine ward or patient-based medical education. These limitations have resulted in new challenges for medical students, especially the final year students in completing their mandated curriculum. We are suggesting a revised curriculum for final year medical students, by following which we can address COVID restriction while making sure all competencies have been achieved by students. This revised curriculum centers around the usual placement of students in Surgical Assessment Unit (SAU), however all students will be posted in simulation wards/labs on their turn to enhance and consolidate their understanding and learning of common surgical cases in these wards, so that they can replicate these skills in SAU and wards on their turns. This article highlights how the proposed curriculum addresses the learning needs of final year medical students in their surgery rotation. The article will also summarize the critical appraisal process of our curriculum in the context of curriculum design theories. Finally, the article will highlight the quality assurance measures adhered to while developing the curriculum.

Two samples of the defectdouble perovskites with general formula Sr2CaNbO5.5 and Sr2CaTaO5.5 were synthesized and their cap abilities in the removal of neutral red dye investigated. Both samples have faced cubic perovskite-type structure in space group Fm3m. The replacement of Nb5+ by Ta5+ has influenced both crystal size and density of the two oxides but showed no impact on the removal capacities. The crystallite size of Sr2CaNbO5.5 and Sr2CaTaO5.5 was determined to be 93.56 and 43.69 nm respectively. The maximum removal capacities of Neutral red are found to be 190.5 mg/g using both the two oxides. This result is consistent with the cell volumes which displayed similar values. The removal of Neutral Red has a negative relationship with temperature but steadily increases as pH increased.

We report 2 cases of vitamin B12 deficiency in children due to deficient intake. These were 2 girls aged 4 years (case 1) and 6 years (case 2), respectively, hospitalized in December 2020 and March 2021 in the pediatric ward of Le Dantec hospital. Both patients presented with aregenative anemia, melanoderma and undernutrition. The bone marrow count in case 1 showed a dysmyelopoiesis with megablastosis. The blood vitamin B12 level was low in both cases. Folic acid blood levels were normal in both patients, but an associated martial deficiency was found in case 2. The dietary survey revealed a lack of intake of animal products rich in vitamin B12. Vitamin B12 replacement therapy was effective with rapid regression of all clinical signs observed in both children. The control of the vitamin B12 level after 1 month of treatment was normal in both patients. The disappearance of the symptoms under substitute treatment confirmed the deficiency of Vitamin B12 intake in both patients. Conclusion: Both of our patients had a profound Vitamin B12 deficiency in a context of deficiency in nutrition. The regression of the symptoms was spectacular under vitamin B12 replacement therapy, confirming the deficiency. We recommend in our context a contribution in micronutrients such as vitamins in children after weaning to avoid dietary errors.

Sugar cane production requires a number of operations to be carried out in the field through number of implements and machines. Therefore, time consuming and required large amount of energy. A combined field cultivator was designed in Kenana agricultural implements factory (KAIF) to carry out at one time multi operations (cultivation, furrow-reforming and Fertilizer placement). This is to increase field productivity, reduce farm power and lower operation time and cost. The combined implement was evaluated in Kenana cultivation fields and compared with three individual implements, rigid tine cultivator, furrow-reformer and fertilizer applicator. The measured parameters were drawbar pull, power requirements, field capacity, fuel consumption and total time in the field. The results showed highly significant differences at 1% level between the different implements for the field capacity, fuel consumption and significant differences at 5% for the drawbar pull. A power requirement in (kW) for the combined cultivator was 77% of those individual implements. Total time per feddan to accomplish the required operations by the combined cultivator was 57% of that required by the individual implements. Fuel consumption was reduced to 57% when combined implement was used compared to that consumed by individual implements. It was concluded that the combined cultivator was effective in increasing field productivity and reducing power and cost of operation.

Auto transplantation is a fast and economical option when a suitable donor tooth is available for replacement of a tooth considered impossible to treat. The purpose of this case report is to describe methods used for autotransplantation and its advantages for cases with a missing bilateral mandibular firstmolar, as compared with a dental implant, removable partial denture, and other methods of prosthesis. In the present patient who underwent auto transplantation, clinical and radiographic outcomes were considered satisfactory at one and two years postoperatively. Bone healing was observed around the roots of transplanted teeth, which showed good function. In autotransplantation cases, even when the donor tooth has complete root formation, a high success rate can be achieved when the patient is properly selected and treated. Although the chance of root resorption remains because of necrotic pulp and periodontal irritation during manipulation, auto transplantation should be considered as a good treatment modality in feasible cases. Based on the present findings, even though autotransplantation is not common in general dental practice, we consider that it offers a clinically and economically viable alternative as compared to other more complicated prosthetic and dental implant treatments. The purpose of this report is to show that auto transplantation is a superior treatment method for single molar defects as compared to other prosthetic methods, as the periodontal ligament of the patient can be used and cutting adjacent teeth is avoided. In addition, it is a treatment method that can effectively utilize a wisdom tooth.

Breast implant-associated anaplastic large cell lymphoma (ALCL) is a recently recognized type of T-cell lymphoma that can develop following breast implants, with morphologic and immunophenotypic features indistinguishable from those of ALK-negative ALCL. Here we report a case of a 58-year-old woman with a history of subglandular silicone implants placed for bilateral breast augmentation 25 years ago, who presented with bilateral breast pain and was found to have bilateral Baker Grade III capsular contracture, and heterogenous fluid collection centered near the left third costochondral articulation, a suspicious left chest wall lesion, and left axillary lymphadenopathy on imaging. A left axillary lymph node core biopsy and an aspiration of the fluid were performed, and no malignant cells were identified. The patient underwent bilateral removal of breast implants and total capsulectomies. Microscopic examination of the capsule surrounding the left breast implant revealed large pleomorphic tumor cells in a fibrinous exudate. By immunohistochemistry, the tumor cells were found to be positive for CD3 (subset), CD4, CD7, CD30 (strong and uniform), and CD43, and negative for CD2, CD5, CD8, and ALK1, supporting the diagnosis of breast implant-associated ALCL. No lymphoma cells were identified in the right breast capsule, confirmed by CD30 stain. Breast implant-associated ALCL is a very rare disease that can develop many years after breast implant placement. Proper evaluation with breast imaging and pathologic workup is essential to confirm the diagnosis in suspected cases. Our case highlights that adequate sampling is important in the investigation of patients with suspected breast implant-associated ALCL.

Background Older adults with hip joint osteoarthritis, a major cause of chronic progressively disabling highly painful functional experiences, may require a surgical joint replacement procedure known as total joint arthroplasty surgery. Objective This review aimed to address the question of whether there an association between hip joint arthroplasty infection rates and prevailing pre or preoperative vitamin D levels that warrants consideration in efforts to prevent or minimize infection related hip arthroplasty complications among older adults particularly during the current ongoing COVID-19 pandemic. Methods PUBMED, SCOPUS, and WEB OF SCIENCE articles related to the topic and published between January 2016-2021 were searched, examined, and summarized. Results Older adults with hip joint osteoarthritis and low vitamin D serum levels who undergo total hip joint arthroplasty surgery may be at higher risk for post-operative infections than those with adequate vitamin D serum levels. Conclusion More research to verify whether efforts to screen for, and maximize vitamin D levels, before and after surgery, as indicated, may be helpful in the context of minimizing total hip joint arthroplasty surgery infection susceptibility and severity among older vitamin D deficient severely disabled hip osteoarthritis cases.

Open bite malocclusion, due to it’s multifactorial etiology, has always been considered a difficult problem to treat. Often associated with transverse maxillary deficiency, this is a real challenge in the field of orthodontics. The traditional approach, for this type of anomaly, in adult patients, is orthognathic surgery and RME (rapid maxillary expansion). There are several approaches to the treatment of adult patients using digital technology. Mini-implant supported palatal expander limits the side effects of the conventional RME and is less invasive compared to orthognathic surgery. Precise and predictable mini-implant insertion, using a customized surgical guide, provides a safe therapeutic approach. This case report combines Cone-beam computed tomography (CBCT), laser scan superimposition, computer-aided design (CAD) and 3D printing in order to design and print a customized surgical guide for orthodontic mini-implant insertion. A CBCT scan was performed to determine the optimal site for mini-implants’ placement. Using the 3Shape Trios Intraoral Scanner the maxilla and the mandible were laser-scanned. Blue Sky Plan 4 software was used to design the surgical guide, and RayWare software was used for printing it. 4 mini-implants were inserted using a safe and predictable technique. The 3D technology represents the future of orthodontics, reducing the risks, chair-side time while providing the best treatment plan for the patient.

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.

Introduction The human tibia is a complex anatomical unit and the knowledge of its morphometric values is important in Forensic, Anatomic and Radiological cases in order to identify unknown bodies and stature. Objective It was to analyze the tibia, its morphometry, side difference and to investigate the position of nutrient foramina in tibia. Methods In this study, 60 adult human tibias (30 right and 30 left) were obtained from the Department of Anatomy SMSR SHARDA UNIVERSITY. In the study a total of two parameters i.e. Cross Section Index in the middle and Cnemicus Index of the bones were obtained and evaluated by using two instruments- a Measuring Tape and a Vernier Calipers. All the bones were dry and showed normal anatomical features. Results The mean Cross Section Index in the middle was calculated as 80.42 ± 11.33 on the right side and 78.15± 12.78 on the left side; and the Cnemicus index was 78.40 ± 13.19 on the right side and 70.84 ± 11.38 on the left side Conclusion The two parameters in the North Indian population were compared with other populations. The values were found to be almost comparable however there were subtle differences between different populations. The position of nutrient foramen was also assessed. This knowledge will thus help further researchers and orthopedic surgeons in various procedures like joint replacement therapy, fracture repair, bone grafts and vascularized bone microsurgery as well as in medico‐legal cases.

Purpose To report a rare case of Inverting Papilloma originating from the Lacrimal Sac in Tertiary Hospital. Method Case report. Results Inverting papilloma is uncommon in lacrimal sac. More often presents in Maxillary sinus, Ethmoid sinus and lateral wall of nasal cavity. This case of 69 years old, Filipino male, who presented with a two-year history of gradually enlarging left medial canthal mass, and tearing. There were no ophthalmoplegia, visual disturbances, proptosis or pain but there was globe displacement superolaterally. Other ophthalmologic examinations were unremarkable at that time of examination. Orbital CT-scan revealed: Heterogenously enhancing mass extending to ipsilateral nasolacrimal canal and nasal cavity causing mass effect. There was note of a suspicious area of hyperostosis. Patient was referred to the Department of Otolaryngology Head and Neck Surgery for co-management. Punch biopsy was done and histopathology revealed Inverting papilloma. Combined surgical management of anterior Maxillectomy via lateral Rhinotomy approach and Dacryocystectomy was done. Intraoperatively, there was note of adhesions to bone in the area of the Lacrimal Sac corresponding to the area of hyperostosis on CT-scan. Post-operative recovery was unremarkable with unchanged visual acuity and extraocular muscle movement. Conclusions This is a case of an inverting papilloma involving the lacrimal sac and nasolacrimal duct that was managed with combined anterior maxillectomy via Lateral Rhinotomy approach and dacryocystectomy for complete resection. We recommended complete resection of the tumor to minimize recurrence. Origin in the Lacrimal Sac area was confirmed by intraoperative findings which correlated with CT- scan findings.

The main purpose of the impression is to record and transfer the relationship between implants and to reproduce this relationship as accurately as possible. But, Unplanned placement of the implants may result in close approximation of the implants, thereby posing tough challenge to the restorative dentist, to first accurately record the impression and later on fabricate the prosthesis with satisfactory esthetics and function. This article presents a modified direct impression coping procedure for precise making of impression of closely placed implants which otherwise may be difficult to replicate the exact position of the implants by conventional direct or indirect technique.

In deaths and diseases attributed to tobacco smoke cardiovascular events exceed cancer and respiratory diseases. Second hand smoke promotes the development of arteriosclerosis and can trigger acute changes of endothelial function and blood coagulability. Indoor smoking bans reduced coronary syndrome and myocardial infarction 10-20% within one year and were followed by sustainable decreases of stroke and diabetes. With a smoke-free hospitality industry people recognized tobacco smoke as an air pollutant, smoking in public was denormalized and social acceptance of smoking in front of children and pregnant women decreased also in homes and cars. Combined effects with ambient air pollution are proven for active smoking and suspected for SHS. Contamination with third hand smoke (THS) persists for months in homes and cars, creating secondary pollutants that in some cases are more toxic (e.g. nitrosamines). Remnants found in air, dust, and on surfaces (carpets, wallpapers, upholstery, soft toys) were associated with their metabolites in saliva of children and in urine of nonsmokers residing in homes previously occupied by smokers. In animal experiments effects of THS were found on thrombogenesis, insulin resistance through oxidative stress, on the developing immune system, lipid metabolism and alterations in liver, lung, skin and behavior. Much less is known about health effects for bystanders from the aerosols exhaled during “vaping” of e-cigarettes, but nicotine and other toxins from e-cigarettes are certainly a hazard, which should be prevented by the use of dermal and oral nicotine products, which are safer for nicotine replacement and without risk for bystanders.

Mini screws represent a new treatment modality in orthodontic biomechanics. They provide absolute anchorage, no secondary movements and reduced orthodontic treatment time. Futhermore, the surgical procedure for mini implants placement is quite simple and this type of treatment requires no patient compliance. We selected a clinical case in order to emphasize one of the most important indications of the mini implants: retrusion of the upper incisors for a incresed overjet case in a young patient. Two mini implants were placed in order to obtain the correction of the overjet and the retrusion of the anterior teeth. The retrusion was obtained in a reduced period of time using retraction devices on crimpable hooks.

Vitamin D, the sunshine vitamin, is now recognized not only for its importance in promoting bone health in children and adults, but also for its other health benefits, including reducing the risk of chronic diseases such as autoimmune diseases, common cancer, and cardiovascular diseases. Ultraviolet radiation of the sun with wavelengths of 290-310 nm penetrates into the skin and converts 7-dehydrocholesterol to previtamin D3, which quickly transforms to vitamin D3. Vitamin D (D represents either D2 or D3) made in the skin or ingested through diet is biologically inert and requires two successive hydroxylations first in the liver on carbon 25 to form 25-hydroxyvitamin D 25(OH)D and then in the kidney for a hydroxylation on carbon 1 to form the biologically active form of vitamin D, 1,25-dihydroxyvitamin D (1,25(OH)2D) 121419. The concentration of the produced 25-hydroxy vitamin D in blood circulation is 1,000 times more than 1,25-dihydroxy vitamin D 4, and it is regarded as a standard indicator of vitamin D status in humans 3. 25-hydroxy vitamin D half-life is about 2-3 weeks and it is regulated by calcium (Ca), phosphorus (P), and serum parathyroid hormone (PTH) to some extent. 25-hydroxy vitamin D content also reflects the amount of vitamin D produced in the skin after exposure to sunlight or received through food intake 56. Guidelines for vitamin D insufficiency/deficiency defined by serum 25(OH)D concentrations have been published from many countries and regions all over the world 7891011. Vitamin D deficiency is a pandemic problem. According to global estimations, more than one billion people around the world suffer from vitamin D deficiency. Among Iranian population, the incidence of vitamin D deficiency varies from 2.5 to 98.5% based on geographic area 1213. Various factors may give rise to vitamin D deficiency, including skin pigments, low levels of vitamin D in diet (insufficient fish oil and egg yolk intake), malnutrition, genetic factors, exclusive breast feeding, vitamin D deficiency of mother during pregnancy, prematurity, chronic use of drugs (e.g., anticonvulsants, aluminum-containing anti-acids, rifampcin, isoniazid, antifungal drugs, antiviral drugs, and glucocorticoids), winter and obesity 113. Cultural habits, the need for full body coverage during outdoor activities and the lack of sunlight programs are the risk factors for low vitamin D levels in women 151617. Children enter foster care due to early childhood adverse experiences such as poor prenatal and infant health care, food insecurity, chronic stress, and the effects of abuse and neglect. As a result, they are at higher risk for poor physical, psychological, neuroendocrine and neurocognitive outcomes compared to others. Foster children are at risk for growth and nutritional deficiencies due to their poor nutritional environment prior to placement in foster care. Insufficient caloric intake results in growth deficiencies. Evidence showed that the risk of stunting and underweight is high in this population 18. The risk of developing hypovitaminosis D was significantly higher in children living in foster homes. One reason is that they are at higher risk of child abuse, emotional deprivation and physical neglect than children living with their families. Moreover, these children most likely do not spend much time outdoors and they lack adequate sun exposure. Another reason is that as children grow up in institutional care, they shift from a diet of vitamin D–fortified formula milk to cooked food, which may not be fortified with vitamin D 1. Iranian government has made some efforts to apply efficient interventions to reduce the prevalence of vitamin D deficiency, and the country’s healthcare system should be managed through accurate planning. Yet, in this country, studies on vitamin D deficiency in children living in foster homes are very limited, and given that timely diagnosis and treatment of this deficiency is vital, this research is conducted in Ali Asghar foster home in Mashhad, Iran.

Background: Despite liberal abortion laws and wide availability of contraceptives in Ghana, declining Post Abortion Contraception remains a public health challenge due to early unplanned pregnancies and recurrent abortions. The development of this model was therefore to address challenges of low contraception following induced abortion in health facilities within the capital city of Ghana. Method: The development of this model was an outcome of a nested study title: ‘decision making for induced abortion in Accra metropolis, Ghana’ in 2014. This model was piloted for four years using Marie Stopes, Ipas and Ghana Health Service trained abortion providers with family planning skills in one hundred purposively selected health facilities comprising 90 private and 10 Non-Governmental Organization mandated by law to provide safe abortion care services in the capital city of Ghana. The model mainly focused on contraceptive products, pricing, placement, promotion and people. Results: There was an increase (90% average) in Post Abortion Contraception across the selected facilities following the intervention using the model. Conclusion: The study concludes that an integration of products, pricing, placement, promotion and people with options counselling prior to an induced abortion are key considerations for an improved post abortion contraception uptake in developing countries.

Background and Context: Autologous bone grafts require a second surgical exposure to harvest the graft with a significant risk of post-operative complications and donor site morbidity. Employment of allografts potentially eliminates donor site morbidity but carries the potential of causing foreign body immune reactions with a high rate of rejection and failures. Hence, Alloplasts have emerged as novel materials to overcome the drawbacks of autogenous and allogenous bone grafts. Today’s advanced dentistry is enterprising a putty form of calcium phosphosilicate (CPS) into several aspects of reconstructive domain of dentistry including the sinus augmentation procedures, osseous regeneration of periodontal bone defects, cystic cavity defects and alveolar socket preservation. This eccentric multifaceted study was planned as an honest effort on the path of proving the efficiency of CPS as an alloplastic bioactive graft material and aimed at quantitative evaluation of regenerated bone radiographically using Cone Beam Computed Tomography (CBCT) scans following sinus augmentation procedures. Materials and Methods: A total of 20 sinus augmentations were carried-out in 17 patients satisfying the criteria (inclusion and exclusion) requiring placement of implants in atrophic maxilla and in other situations of anatomic constraints. The graft material used was calcium phosphosilicate (CPS) putty (Nova bone dental putty, Novabone products, Alachua, Fla). The residual bone height was recorded using CBCT scans and a computer based software where the measurements were made from the crest of the ridge till the sinus floor lining. The patients were assessed clinically at immediate post-operative, 1 week, 1 month, 3 months and 6 months follow-up recalls post-operatively. Radiographic assessment for bone height was done pre-operatively and at 6 months follow-up recall post-operatively using Cone Beam Computer Tomography scans. Results: The post-treatment bone height (11.76+0.97mm) was found to be significantly higher than the pre-treatment bone height (6.8 +0.70mm) in indirect sinus augmentation procedures (t=14.4, p<0.005). In case of direct sinus augmentation group also, the post-treatment bone height (11.27 +0.71mm) came-out to be significantly higher than the pre-treatment bone height (2.44 +0.81mm) (t=32.17, p<0.005). The post-treatment bone grafted sinus floor measurements (1107.6 + 155.6mm) were also found to be significantly higher than the original sinus floor measurements of bone density (Grayscale values) (412+ 65.5mm) (t=16.6, p<0.001) in case of indirect sinus augmentation procedures. Similarly, the post-treatment bone grafted sinus floor measurements (1169.6+136.7mm) were found to be significantly higher than the original sinus floor measurements of bone density (Grayscale values) (416.4+ 0.70mm) (t=17.9, p<0.001) in case of direct sinus augmentation group. Conclusion: Calcium Phosphosilicate (CPS) was accepted well at the recipient sites without any complications demonstrating its efficiency and reliability in sinus augmentation procedures.

Context: The present study was undertaken to do a comparative evaluation of the role of Cone Beam Computed Tomography (CBCT) imaging and Orthopantomography (OPG) for pre-operative implant planning in combination with sinus grafting procedures in order to assess sinus anatomy and morphology and the existing bone height in three dimensions. Aims: To assess sinus anatomy and morphology and the existing bone height in three dimensions. Materials and Methods: Pre-operative assessment of maxillary sinuses for implant planning using CBCT imaging was performed on 20 sinuses (17 patients). These patients were subjected to orthopantomographs and CBCT imaging both pre-operatively and post-operatively. CBCT imaging helped to decide the type of sinus augmentation procedure best suited for the patients as per the individual needs and depending on the residual alveolar bone height, timing of implant placement, sinus morphology, anticipation of complication and comparative analysis between pre-and post-procedural gain in vertical alveolar bone height and increase in bone density. Statistical Analysis: The results were tabulated and statistically analyzed using Paired and Unpaired t-tests. Results: In the majority of cases, there was a concordance between the treatment type based on pre-operative and post-operative CBCT scans. The assessment of sinus morphology revealed a significantly higher detection rate of abberations in the form of sinus mucosal hypertrophy and septae on CBCT which were imperceptible on routine radiographs. The most appealing result was that vertical alveolar bone height could be measured precisely and there was a significant increase in surgical confidence and a significantly better prediction of complications when using CBCT imaging. Conclusions: A pre-operative planning based on CBCT imaging seems to improve sinus diagnostics and helps to execute a better treatment plan. Also, it is a good tool for the comparison of vertical alveolar bone height pre-and post-operatively following sinus augmentation procedures using various graft materials.

Female fertility is an economically important trait in the dairy industry, and the fertility selection index has been developed as a method of including female fertility in the breeding goals of this industry. This index considers a combination of factors, including days open, number of inseminations per lactation, success after first insemination, and pregnancy within 70 d, 90 d, and 110 d after parity. Based on a genome-wide association study of the fertility selection index using 442 Holsteins, we found that the index is influenced by a variation in the thioredoxin fold region of the family with the sequence similarity 213, member A (FAM213A) protein. FAM213A is a CXXC motif-containing peroxiredoxin 2-like protein that regulates cellular redox status. A replacement of isoleucine with valine in FAM213A was associated with poor fertility in cows. The overexpression of FAM213AVal in bovine endometrial epithelial cells reduced reactive oxygen species to a lesser extent relative to the overexpression of FAM213AIle and caused a decrease in cyclooxygenase-2 expression. Downregulation of cyclooxygenase-2 led to a decline in prostaglandin E2, which is critical for implantation because it protects the conceptus from the maternal immune system. Cows with FAM213AVal showed lower levels of prostaglandin E2 than did cows with FAM213AIle, suggesting that cows with FAM213AVal are less fertile than cows with FAM213AIle because of their reduced uterine environment. Thus, the present study found that FAM213A unexpectedly modulates female fertility in cattle.

Objectives: The study was aimed to find out which of the two techniques, medial or lateral side of the temporalis fascia graft was better in underlay method for correcting the perforations of the tympanic membrane keeping all other factors constant. Methods: We designed a prospective randomized study from Jan 2010 to Jan 2013 at Buraidah Central Hospital, Al Qassim, Saudi Arabia. Eighty patients having dry central; moderate, large and subtotal perforations of the tympanic membrane were subjected for tympanoplasty type –I by underlay technique. In 41 patients the temporalis fascia graft was placed with medial (rough) side up (Technique-I) and 39 patients the graft was placed with the lateral (smooth) side up (Technique-II). Results: The graft take up rate was 95.1% in technique-I and 87.2% in technique -II. Failure rate was 4.9% in technique – I and 12.8% in technique – II. Conclusion: Technique – I was judge to be giving better result because: 1.Rough surface of the medial side of the graft after moistening enhances wetting, increases the critical surface tension and broadens the contact surface. 2.The friction due to rough surface resists displacement forces between the graft and remains of the tympanic membrane. 3.Rough surface of the medial side of the temporalis fascia increases the adhesion power and increases the overlap between the two surfaces. To the best of our knowledge this is the only such prospective study for this method.

Vocal fold scarring is a clinical problem without reliable treatment. Tissue engineering of a vocal fold replacement is an exciting potential treatment for vocal fold scars that involve multiple layers of the vocal fold. Human adipose-derived stem cells (ASC) were previously used to produce a promising vocal fold cover layer replacement. However, relevant in vivo studies are needed before human application, and implanting the human cells in animal larynges would introduce significant risk and data confounding. We therefore report here the development of a construct based on rabbit ASC with the potential for use in pre-clinical implantation studies. Rabbit ASC were isolated and cultured in a three-dimensional fibrin matrix to create an implantable construct resembling the vocal fold mucosa. Key differences between the human cell and the rabbit cell models are highlighted.

Continuous-time glucose monitoring (CGM) effectively improves glucose control, as oppose to infrequent glucose measurements (i.e. using Lancet Meters), by providing frequent blood glucose concentration (BGC) to better associate this variation with changes in behavior. Currently, the most widely used CGM devices rely on a sensor that is inserted invasively under the skin. Because of the invasive nature and also the replacement cost of sensors, the primary users of current CGM devices are insulin dependent people (type 1 and some type 2 diabetics). Most non-insulin dependent diabetics use only lancet glucose measurements. The ultimate goal of this research is the development of CGM technology that overcomes these limitations (i.e. invasive sensors and their cost) in an effort to increase CGM applications among non-insulin dependent people. To meet this objective, this preliminary work has developed a methodology to mathematically infer BGC from measurements of non-invasive input variables which can be thought of as a “virtual” or “soft” sensor approach. In this work virtual sensors are developed and evaluated on 20 subjects using four BGC measurements per day and eight input variables representing meals, activity, stress, and clock time. Up to four weeks of data are collected for each subject. One evaluation consists of 3 days of training and up to 25 days of testing data. The second one consists of one week of training, one week of validation, and 2 weeks of testing data.
