After kidney transplantation, BK polyomavirus reactivation can manifest as nephropathy in 1% to 10% of patients. PCR testing of urine and blood is commonly used to screen for BK polyomavirus nephropathy. The study aims to detect BK virus infection in kidney transplant patients to prevent tubulointerstitial nephropathy and graft loss. This retrospective study includes 26 patients who underwent kidney transplants between January 2019 and December 2023. We diagnosed BK virus infection by performing real-time PCR on blood and urine samples. BKV DNA was detected in 3 patients. Reducing immunosuppressive therapy led to negative PCR results and favorable clinical and biological outcomes in these 3 patients.

Water deficit is a fundamental factor in public health and economic growth. Water supply and population growth are directly linked to water demand. The physio-chemistry and microbiology analysis of water is utmost significance in dietary requirements. Drinking water has the main concern especially it affects food security. This study includes a number of representative sites where 24 water samples (from wells, reservoirs and tap water) were analysed. These sites are located in the western villages of Baalbeck, the main city of the Bekaa Plain in Lebanon where the analysed water is used mainly for domestic needs and for irrigation. This study investigates the physiochemical and microbiological properties. Among the selected sites, Hawsh Barada site shows a strong contamination by nitrate. At the Nabi Rashaded (tap), Beit Shema and Bednayel (borehole and tap), contamination above the norm by zinc ion was noted. From a microbiological point of view, Hawsh barada, Nabi-Rashadeh, Hawsh-bay, and Beit shema are markedly polluted and do not meet the standard for drinking water. Hence, water quality in Hawsh barada, Nabi-Rashadeh, Hawsh-bay, Beit shema and Bednayel are not suitable for drinking, and this must be informed to decision makers who can act implementing environmental controls for health protection in the studied region.
Numerous instances of consecrated communion wafers turning into human tissue and blood have been reported throughout history and the contemporary international media, referred to as Eucharistic miracles. Various suggestions have been put forth to explain such phenomena, ranging from miraculous to natural. Here, a novel demonstration is provided showing that the appearance of a bleeding host can occur by placing ordinary, non-consecrated wafers under similar conditions as described for many of these events. Using basic forensic methods, distinctions between ensuant reddish areas and genuine blood were noted. In previous studies with miracle wafers, isolated DNA was resistant to amplification with human-specific primers, which has been attributed to its divine nature. The current study shows that multiple types of non-human DNA existed in unconsecrated wafers, providing an alternative explanation for such findings. Finally, a minimal protocol of scientific examination is outlined to aid in the standardization of such investigations in the future, including a distinctive approach to authenticate the genuine shared origin of such occurrences.

Methylenetetrahydrofolate Reductase (MTHFR) is an important enzyme of the folate cycle, which is required to convert 5,10-methyltetrahydrofolate into 5-methyltetrahydrofolate (5-methylTHHF). 5-methyl THF is a methyl group donor for several cellular methylation processes. It also donates methyl group for the conversion of homocysteine into methionine, the higher concentration of which is toxic. MTHFR gene C677T polymorphism is clinically important polymorphism and the variant MTHFR (A222V) enzyme has reduced activity, hence increasing the requirement for folic acid. Less conversion of folate to 5-methyl-THF due to C677T polymorphism results in a higher plasma concentration of homocysteine (hyperhomocysteinemia). Individuals having C677T polymorphism are susceptible to various diseases, including reproductive problems like male infertility, polycystic ovary syndrome, Recurrent Pregnancy Loss (RPL), Preeclampsia (PE), placental abruption, and adverse pregnancy outcomes. MTHFR C677T polymorphism mimics folate deficiency, and folate is required for DNA synthesis, repair, methylation, and proper chromosome segregation, and all these processes are important for foetal growth and normal development. Methylation and demethylation processes control the gene expression of about 45% of human genes. Impaired methylation influences the expression of genes involved in the regulation of hormones, spermatogenesis, and oogenesis. In males, oxidative stress damages sperm DNA decreases sperm motility, and may impair fertilization capability. In pregnant women, hyperhomocysteinemia increases oxidative stress and inflammation within the placenta, which causes damage to placental tissue, impairs its function, and disrupts foetal development. Further, hyperhomocysteinemia (HHcy) is embryotoxic and neurotoxic and is responsible for congenital anomalies in the foetus. This review supports the idea that MTHFR C677T polymorphism is associated with an increased risk for male infertility, PCOS, RPL, PE, and congenital anomalies. This review may provide a clue toward a better understanding of the correlation between the MTHFR C677T polymorphism and its detrimental effects on human reproductive health.
The integration of deep learning and genetic analysis has transformed the assessment of elite sports performance, particularly in competitive swimming. This study examines the fusion of deep learning techniques with DNA markers, physiological biometrics, and performance analytics to enhance the prediction and optimization of swimmer performance. A structured dataset comprising genetic sequences, physiological parameters, and biomechanical attributes was utilized to train a neural network model capable of categorizing swimmers based on genetic predisposition and athletic potential. The model achieved high classification accuracy, demonstrating a strong link between genetic markers, physiological traits, and competitive swimming outcomes. The findings emphasize the potential of AI-driven analytics in talent identification, customized training adaptations, and injury prevention. Furthermore, the study highlights the effectiveness of deep learning in analyzing complex genomic and physiological data to generate meaningful insights for performance enhancement. While the results validate the feasibility of using genetic and AI-based models for performance prediction, further studies are needed to broaden dataset diversity, integrate epigenetic influences, and test the model across varied athlete populations. This research contributes to the expanding field of AI-driven sports science and provides a solid foundation for incorporating genomics with deep learning to enhance elite athletic performance.
