This research delves into the association of Kisspeptin and the KISS gene (rs35431622) single nucleotide polymorphism with circulating sex hormones and semen parameters in males diagnosed with infertility. Eighty male participants were recruited from fertility clinic, were divided into two groups: Group A, characterized by normal sperm count and Group B, exhibiting low count. The analysis involved assessing hormone levels Kisspeptin, follicle stimulating hormone, luteinizing hormone, total testosterone and sex hormone binding globulin by utilizing ELISA, investigating the association of the KISS gene SNP with these variables through Tetra amplification refractory mutation system-PCR and Gel Electrophoresis. The findings revealed that males a low sperm count displayed notably reduced levels of Kisspeptin and free testosterone, accompanied by increased luteinizing hormone and follicle stimulating hormone. The KISS gene SNP rs35431622 (Q36R) demonstrated a 53.3% frequency of the heterozygous mutant TA genotype and OR 0.19 (CI 0.05-0.71) among infertile males, indicating its potential implications a risk factor for male infertility. This study emphasizes the significance of Kisspeptin in overseeing male reproductive health and highlights its potential as a marker for hormonal dysregulation in male infertility.

Marfan syndrome (MFS) is an autosomal dominant disease caused by mutations in the gene (FBN1) of fibrillin-1, a major determinant of the extracellular matrix (ECM). Functional impairment in the cardiac left ventricle (LV) of these patients is usually a consequence of aortic valve disease. However, LV passive stiffness may also be affected by chronic changes in mechanical load and ECM dysfunction.

Risk-adapted treatment protocols conferred remarkable improvement in the survival rates of pediatric acute lymphoblastic leukemia/lymphoma (ALL/LBL). Nevertheless, clinical management is still challenging in certain molecular subgroups and in the presence of alterations associated with an increased rate of relapse. In this study, disease-relevant genomic and transcriptomic profiles were established in a prospective, multicenter, real-world cohort involving 192 children diagnosed with ALL/LBL.

Background/objectives: The study of DNA transfer and persistence has become increasingly significant, driven by advancements in DNA detection sensitivity and the need for reliable forensic evidence. In forensic investigations, saliva and saliva-stained materials are recognised as valuable DNA sources, particularly in cases of homicide, sexual assault, and burglary, where saliva can be transferred between individuals during the criminal act. The time between the crime and sample collection is a critical factor that can influence the success of the analysis.

Fowl adenovirus D is the main cause of inclusion body hepatitis in chickens. Whole genome sequencing was carried out to enrich the genomic sequence database using field isolates of FAdV-D. Out of 44 newly determined genomes, 43 were classified into FAdV-2/-11 and 2 into FAdV-3; no FAdV-9 was identified.

Objective: Quercetin is a flavonoid compound extracted from fruits and plants and is used as a natural antioxidant to prevent or treat a variety of diseases such as cancer, obesity, chronic inflammation, and reproductive system dysfunction. The aim of this study was to investigate the effects of quercetin on obesity and ovarian tissue by analyzing the expression of genes involved in the hypothalamus-pituitary-gonadal axis, including ob-Rb, ob-Ra, and brain-derived neurotrophic factor (Bdnf), neuropeptide Y (NPY), and Kisspeptin (Kiss-1).
Methods: In this experimental study, female rats were divided into three groups, and the effect of quercetin with doses of 50 and 100 mg/kg on weight and BMI was investigated.
