We have successfully characterized the structure of testosterone, one of the essential steroids, through high-resolution rotational spectroscopy. A single conformer has been detected, and a total of 404 transitions have been fitted, allowing a precise determination of the rotational constants. It allowed us to unravel that the isolated structure of testosterone adopts an extended disposition. The results obtained in this work highlight how using laser ablation techniques in combination with Fourier transform microwave techniques allow the study of large biomolecules or common pharmaceuticals. It is an important step toward studying relevant biomolecules and developing new analytical techniques with unprecedented sensitivity and resolution.

Cisplatin is an antineoplastic drug that exhibits toxicity dependent on dosage and has adverse reproductive effects. (Bitter melon) is a natural vegetable plant; its active ingredients possess antioxidant, apoptotic, antiproliferative, hypoglycemic, and other therapeutic properties. This study evaluates the effect of the administration of bitter melon extract, cisplatin, and cisplatin/bitter melon cotreatment on liver and kidney functions, serum and testicular oxidative status, testis histology, and sperm parameters.

Background And Aim: Cannabis use disorder (CUD) is strongly influenced by genetic factors; however the mechanisms underpinning this association are not well understood. This study investigated whether a polygenic risk score (PRS) based on a genome-wide association study for CUD in adults predicts cannabis use in adolescents and whether the association can be explained by inter-individual variation in structural properties of brain white matter or risk-taking behaviors.
Design And Setting: Longitudinal and cross-sectional analyses using data from the IMAGEN cohort, a European longitudinal study integrating genetic, neuroimaging and behavioral measures.

Relationships between gonadotropins, sex hormones, and vascular structure and function in adolescents of varying weight statuses have not been fully investigated. In the present study, we examined associations among these in female and male adolescents with normal weight or obesity. We performed a cross-sectional analysis of adolescents ( = 58; 12-<18 years) grouped according to BMI percentile (BMI%) into normal weight (5th-<85th BMI%; = 25) and obesity (≥95th BMI%; = 33) categories.

Bisphenol A (BPA) is a widely used industrial compound commonly found in various everyday plastic products. Known for its endocrine-disrupting properties, BPA can enter the human body through multiple pathways. Prenatal exposure to BPA not only disrupts placental structure and function but also interferes with normal steroid metabolism.
