RETRACTED: Leap into Fetal Surgery; In Utero Placental Mesenchymal Stem Cell Therapy, A Contemporary Approach to Treating Myelomeningocele

This article has been retracted on April 10, 2025. VIEW THE RETRACTION NOTICE (https://doi.org/10.14302/issn.2997-2086.jfs-25-5857) Myelomeningocele (MMC), a class of spina bifida is a type of neural tube defect. According to the U.S. Centers for Disease Control and Prevention, each year approximately 1,400 babies born in the United States have spina bifida. The disease manifests with the lack of skin and bone covering the caudal part of the spinal cord. The patient developing such a condition often develops lifelong impaired lower limb mobility accompanied by hydrocephalus, and urinary and bowel incontinence. The available interventions include prenatal and postnatal surgery to fuse the dura. Prenatal surgery performed before 26 weeks of gestation reduces the risk of death or the need for ventriculoperitoneal shunting. It also enhanced results on a comprehensive index for mental and motor function. When compared to postnatal surgery, prenatal surgery reduces the manifestation of several secondary outcomes, including the degree of hindbrain herniation seen in the Chiari II malformation. Stem cell therapy for MMC on animal models of chick, ovine, and rodents with reported cases 15/63, 15, and 136, respectively, using human Embryonic Stem Cells (hESCs), Neural Stem Cells (NSCs), Mesenchymal Stem Cells (MSCs) showed significant coverage of MMC defect and slight neurogenesis was also observed. With an understanding of medical literature about in-utero regenerative capacity, it is to be appreciated that placental stem cells surgically seeded within a biocompatible scaffold of the cell patches can play a part in alleviating the spinal cord manifestation associated with MMC. Documented animal studies show that incorporating Placental Mesenchymal Stem Cells in prenatal surgery has reported improved neurogenesis and lower limb mobility. In an ovine myelomeningocele model, the development of in-utero myelomeningocele repair with human Placental Mesenchymal Stem Cells seeded onto an extracellular matrix (PMSC-ECM) enhances motor findings. The clinical trial for the first stem cell therapy on human subjects known as the “CuRe Trial: Cellular Therapy for In Utero Repair of Myelomeningocele.” is expected to be finished by 2030. So far, the cases undergoing treatment have shown significant leg movement and a greater degree of bowel and urinary control. This FDA-approved clinical trial is envisioned to be the future of treating MMC.

Newly-Detected Solitary Bony Lytic/Sclerotic Lesion with Soft Tissue Mass in a Previously Treated Case of High-Risk Medulloblastoma: Importance of Contemporary Pathology Techniques to Differentiate Second Malignant Neoplasm from Extra-Neuraxial Metastasis 

Multi-modality therapy has led to significant improvement in outcomes for childhood medulloblastoma; however, long-term survivors have become more susceptible to late effects of therapy including induction of second malignant neoplasms and even remain at an increased risk of late relapses including extra-neuraxial metastases. A newly detected solitary lytic/sclerotic osseous lesion in a medulloblastoma survivor away from the radiation field poses considerable diagnostic challenge as it could represent either a second malignant neoplasm or extra-neuraxial metastasis. We report one such case highlighting the importance of contemporary pathology techniques as useful adjuncts to differentiate a second primary osseous Ewing’s sarcoma (ES)/primitive neuro-ectodermal tumor (PNET) from bony metastasis and review the pertinent literature on second malignant neoplasms and extra-neuraxial metastases in medulloblastoma. To the best of our knowledge, this is the first report of a molecularly confirmed second primary osseous ES/PNET in a survivor of childhood medulloblastoma.

A Review and Update on the Biochemical Basis of Conscious Breathing (Pranayama)

Breathing has long been recognised as a vital process in Eastern traditions such as YOGA and Ayurvedic medicine, where Pranayama is regarded as a transformative practice that harmonises body and mind. While the East developed sophisticated systems of breath regulation for health and self-awareness, the West largely overlooked their significance until the late 19th and early 20th centuries. A group of pioneering physicians, sometimes referred to as "the pulmonauts", including Christian Bohr, Konstantin Buteyko, and Peter M Litchfield, explored the physiological foundations of respiration. They emphasised the benefits of slow, nasal breathing and its relationship to both physical and emotional well- being. In the 21st century, contemporary researchers and practitioners such as James Nestor, J. Patrick McKeown and Anders Olsson have expanded this understanding through the fields of biochemistry, physiology, and biomechanics. Their work has clarified the mechanisms underlying conscious breathing and refined ancient pranayama techniques. Integrating insights from both Eastern and Western traditions reveals that breathing is a central factor in maintaining homeostasis and emotional balance.

On Terms: Maladaptive Behavior

There is no shortage of terms that are used to describe and articulate the strategies, practices, and underpinnings associated with the work engaged in by behavior analysis. Two terms that a clinic-focused behavior analyst may hear often are maladaptive behavior and problem behavior. These terms are not only common within our everyday practice, but they are also peppered throughout behavioral literature. Despite their permanency in the behavior analyst's repertoire, their meanings remain inconsistent, interchangeable, and conceptually unclear. For over a century, this lack of precision has gone unchecked, despite extensive research on undesirable or clinically significant behaviors. This article offers individuals a recount of the history, definitional limitations, and functional implications of these terms. From the perspective of early psychological scholarship and contemporary behavior-analytic sources, I argue that the field of Applied Behavior Analysis (ABA) will benefit from distinguishing maladaptive behavior as the presence of behavior that adversely affects the individual, while problem behavior should refer to the absence or inhibition of adaptive responses in relation to others' social behaviors. Furthermore, I propose that both terms be used to describe the effects on the person engaging in the behavior, instead of others around the individual, as a method of improving directionality and functional clarity. As a field focused on verbal behavior, becoming more conceptually precise with our own verbal behavior will lead to a more coherent basis for interpreting and treating behaviors that interfere with individuals' adaptation and well-being.

Intramuscular Fat Deposition and Osteoarthritis Pathology: A Possible Overlooked Pathogenic Correlate?

Osteoarthritis, the most prevalent joint disease and one affecting many aging adults is strongly associated with various degrees of disability and high health costs. Commonly deemed largely incurable and progressive, it appears muscle fat deposition and its encroachment on muscle tissue may account for multiple adverse health outcomes, especially the osteoarthritic disease process. This mini review examines whether contemporary evidence supports a role for efforts towards preventing excess fat infiltration into vulnerable muscles as one means of reducing osteoarthritic pain and disability. To this end, research on this theme and reported as of June 2025 on this issue was sought. We found that with few exceptions and regardless of joint examined a role for muscle mass infiltration in osteoarthritis disability appears of high clinical significance.

Delving into the Ideas of Charles Darwin: A Study of His Pre-Beagle Musings, Beagle Expedition, and Subsequent Developments

Charles Darwin's exploration of the Galápagos Islands in 1835 and his subsequent formulation of the theory of evolution in 1839 were significantly influenced by his observations of land-birds, including finches, larks, owls, and mockingthrushes. Despite a primary focus on geology during his voyage on the HMS Beagle, Darwin meticulously documented various species in his field notebooks. Early observations during his youth at Edinburgh University and the Beagle expedition reflected Darwin's growing curiosity about species variation. However, it was not until his return to England and his interaction with ornithologist John Gould that Darwin began to recognize the significance of the finches he had observed in the Galápagos. This review synthesizes existing literature on Darwin's transition from geological interests to his groundbreaking insights into evolution. By examining primary sources, historical interpretations, and contemporary analyses, this paper highlights how Darwin's observations and Gould's influence shaped his revolutionary theory of species transmutation—the gradual transformation of one species into another over time. The review aims to provide a comprehensive understanding of Darwin's contributions, illustrating how his Galápagos observations and collaboration with Gould laid the foundation for modern evolutionary biology and continue to influence scientific thought on species adaptation and natural selection.

Understanding Inherited Bleeding Disorders: Genetic Mutations in Blood Coagulation Factors and Regulatory Proteins

Hereditary thrombotic diseases, or inherited bleeding disorders, are a group of genetic conditions that disrupt normal blood coagulation. These diseases result from mutations in genes encoding blood coagulation factors or other regulatory proteins, impairing the body's ability to regulate bleeding and clotting. The most common inherited clotting disorders are hemophilia A and B, which are associated with deficiencies in clotting factors VIII and IX, respectively. Von Willebrand disease (VWD) is another prevalent disorder characterized by a deficiency or dysfunction of the Von Willebrand factor, a protein essential for coagulation. Additionally, the Factor V Leiden mutation is linked to an increased risk of blood clots. The prevalence of inherited coagulation disorders varies significantly by region and subpopulation. It is estimated that 5,000 to 10,000 male newborns are born with hemophilia A or B each year. Von Willebrand disease is much more common, affecting about 1% of the global population. The Factor V Leiden mutation is found in significant percentages of certain populations, with 3–8% of Caucasians being carriers. While antithrombin deficiency is more common in some areas, the incidence of other inherited clotting disorders, such as Factor XI, protein C and S deficiencies, and VWD, varies widely worldwide. This study discusses the incidence of inherited clotting disorders and their impact on affected individuals and their families. It also covers new advancements in disease management, alternative therapy approaches, and contemporary diagnostic techniques, aiming to improve diagnoses, treatments, and outcomes for patients with hereditary clotting disorders.

UV rays Decrease Foliar pH in Cress (Lepidium Sativum) and Modify NIR Spectrum

An experiment on watercress (Lepidium sativum) 42 d days after sowing was set up to evaluate the effect of UVAB radiation on foliar pH and on NIR tomoscopy. The effect of 8 h of UV exposure (about 500 µWcm-2) was clear, causing a reduction in the foliar pH of 6.0%, compared to the contemporary control group (5.22 vs. 5.56). When the treated leaves were returned to white light, their pH rose by 1.7% (5.31), reaching the same level as leaves grown outdoors (5.33). On the basis of the NIR spectra, the leaves of the plants grown outdoors were recognized 100%, that is, more than the control leaves (87%) and the plants treated with UV on the day of measurement (81%). However, the effect of the UV marking on the leaves is not permanent as, after the UV treatment, the leaves returned to white light were classified at 61%, which is a greater value than the 37% of overlapping between the two groups. The foliar pH was highly correlated with the NIR spectra, with R2 0.43. These results corroborate the hypothesis of the influence of the solar cycle on the variation of the pH of leaves in plants, which we believe may have played a major role in past agricultural pandemics. These results call for the introduction of the pH test for the evaluation of resistance to pathogens. From the environmental point of view, the foliar pH could be enlisted as an in vivo long-time indicator of the response of plants to climate changes.

Term Paper on The Nature of Cyber Crime and Cyber Threats: A Criminological Review

Cybercrime is one of the fastest-growing criminal activities in contemporary age. The first recorded cybercrime happened in France in the year 1820. It was not as sophisticated as cybercrime we know in our world today, but, still, that was a crime. Cybercrime has evolved globally as the online platform is progressing. While progress is made in the battle against cybercrime there still remains a wide gap in the consistency of laws across international borders. The main objectives of this study are to explore the nature of cybercrime in developing countries, find out the cyber threats for terrorist activities and explain cybercrime and threats from criminological aspects. This is a descriptive study which is based on secondary data. This study is based on previous researches & studies. this paper discusses the nature of cybercrime in developing countries. It could allow developed countries to understand better the national and international effects of that cyber threats, to determine the conditions of current regional and international agreements, and to help countries create a sound legal framework. And then we notice the impact of cyber threats all over the world. At last, we discuss cybercrime from criminological point of view. Cybercrime is not limited to two neighboring countries and cross-border conflicts; an attempt could be conducted from another world. It is fearful to see cyber wars as the easiest way to carry out sabotaging rather than wars such as cold war, chemical and biological wars, terrorist wars or jihadist attacks. The international legal framework aims by the International Criminal Court to keep offenders accountable for their actions. The government has by far the biggest burden and obstacle in raising knowledge of cybercrime among the people.

Avant Garde Alleviation -Cancer Immunotherapy

Novel cancer therapeutics are superior and  prevalent in the current scenario although a subset may not be satisfactorily alleviated or undergo disease relapse with the adoption of conventional chemotherapeutic agents.  Cancer cells can comfortably elude immune destruction as  interaction of cancer cells  with native  immune cells within  tissue microenvironment is a cogent factor in evasion of cancer cells  from pertinent immune surveillance. Thus, cancer immunotherapy can be safely contemplated as  an efficacious and contemporary  treatment modality  for managing  various malignant disorders.

Space of Cross-Disciplinary Researches of Life, Nature and Society

Journal of Biosemiotic Research is a new periodical devoted to a young, actively developing science. A review of recent scientific publications shows that in the broad scientific space of biosemiotics contemporary questions and "eternal themes" interact, not finding an answer in the private sciences - anthropology, semiotics of culture and philosophy1,2. To solve them, the fundamental foundations of science and new achievements, the opportunities of the latest technologies and scientific communications are attracted. Like all young sciences, biosemiotics has many definitions. We give here the most famous ones. "Biosemiotics: (bios, life + semion = sign) is an interdisciplinary field of theoretical and empirical research, analyzing communication and signification in living systems. Signed processes, ranging from molecular to ecological and evolutionary, have been studied throughout the history of biology; however, very often descriptions of information and communication aspects of living systems were considered only metaphorical, believing that the essence of them can be understood with the help of physical and chemical descriptions. In biosemiotics, on the other hand, information sign processes are considered as the primordial, basic system of phenomena of life, requiring a new understanding..."3. "Biosemiotics explores sign systems of various levels: molecular biological (genetic code), intracellular (signal peptides), intercellular (mediators, immune interactions), intraorganism (hormones, conditioned reflex reactions) and interorganism (telergons, pheromones, attractants) ... In addition, biosemiotics covers all the problems associated with the problem of the existence of language and thinking in animals." However, today we can go further and add to the analysis the next stage of evolution, standing between animals and modern human (Homo sapiens sapiens).

Low Energy Intake Impairs Glucose Regulation and Stamina in Japanese Young Women

Energy intake has been decreasing these ten years in Japan, and low energy intake is remarkable especially among young women. We attempted to show the dietary habits and physiological function including glucose tolerance and stamina for endurance-running in contemporary young Japanese women who take insufficient energy. 85 healthy women aged 20.5±1.1 years were enrolled in the present study. Subjects were categorized in two groups; Group I (n=70) with higher energy intake, and Group II (n=15) with lower energy intake than the basal metabolic rate (BMR). Actual energy intake in Group I was 1598.8±282.1 kcal/day, and it was 1019.9±127.1 kcal/day in Group II (p<0.01). Standard 75-g oral glucose-tolerance test was performed, and the capillary glucose value was measured at the fingertip. In Group I, glucose values at fasting, 30, 60 and 120 min were 75.0±9.1, 132.1±25.2, 120.5±27.4, 105.3±19.5 mg/dl, and those in Group II were 78.9±7.7, 155.8±26.6, 142.2±26.6, 112.3±16.0 mg/dl, respectively. The values of Group II at 30 and 60 min showed significantly high (p< 0.01). Stamina and the intake of protein in Group II were significantly lower than those in Group I (p<0.05), and muscle mass and grip strength were less in Group II than in Group I, though there was no significant difference. We indicated with these results that low skeletal muscle was considered to be responsible for the impairment of glucose regulation in Group II. This study showed that young women with low energy intake should take sufficient energy and build skeletal muscle to prevent the impairment of glucose regulation.
