A comprehensive narrative review of the literature was conducted, analyzing studies published between 2014 and 2024. The review focused on genetic predispositions, key hormones regulating exercise performance, and their combined influence on physical development in children. Data were collected from peer-reviewed journals and analyzed using a descriptive approach to identify patterns and practical applications in pediatric exercise science. The review highlights that genetic factors play a foundational role in determining physical attributes such as muscle composition, aerobic capacity, and metabolic efficiency. Key genes, including ACTN3 and ACE, have been linked to variations in strength, endurance, and recovery potential. Hormonal factors, particularly growth hormone, insulin-like growth factor-1, testosterone, and cortisol, dynamically influence exercise adaptation, with significant changes occurring during developmental stages. The interaction between genetic and hormonal influences suggests that personalized training approaches can optimize performance while considering developmental stages and environmental factors. Ethical considerations surrounding genetic testing for talent identification remain a critical concern, emphasizing the need for responsible and evidence-based application in pediatric sports programs. Therefore, it is crucial to understand the relationship between genetic and hormonal factors for designing individualized exercise programs that enhance athletic potential while ensuring long-term health and well-being.

The structures of all compounds were characterized using nuclear magnetic resonance (NMR), Fourier-transform infrared spectroscopy (FT-IR), and elemental analysis. The biological potential of these compounds was evaluated through in vitro antimicrobial assays against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans, and Candida glabrata. Additionally, anticancer activity was tested against A549, HCT116, and BEAS-2B cell lines, revealing promising results for some derivatives. Preliminary catalytic studies demonstrated the effectiveness of the silver-NHC complexes in A3-coupling reactions involving aldehydes, alkynes, and amines. These reactions yielded propargylamines with high conversion rates (up to 90%) using minimal catalyst amounts. This work highlights the dual utility of these compounds as both potent biological agents and efficient catalysts, paving the way for further exploration of their applications in medicinal chemistry and sustainable catalysis.</p>","PeriodicalId":9802,"journal":{"name":"Cellular and molecular biology","volume":"71 5","pages":"118-127"},"PeriodicalIF":1.5,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144141482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
