Exercise attenuates inflammaging and testosterone decline in aged and morphine-treated rats: a role for NF-κB signaling
Aging reduces testicular function by lowering sperm quality and testosterone, worsened by diseases. Morphine addiction harms male reproduction by disrupting hormonal balance and increasing testicular oxidative stress and inflammation. Regular physical exercise can help counteract these effects by boosting antioxidants and supporting sperm production. This study explores how exercise mitigates inflammaging and testosterone decline by modulating the NF-κB signaling pathway in aged male rats with...
The aging male: impact of aging on male reproduction
Aging is a complex process that includes chronological aging and cellular aging. Although chronological aging is irreversible, cellular aging, which is reversible, is closely associated with chronological aging. Understanding the complexity of the impact and mechanisms of aging on the male reproductive function is crucial in maintaining male fertility. This study reviews the effects and mechanisms associated with aging in males on male reproductive health. It also provides potential therapeutic...

Effects of protein-based multinutrient therapy on sarcopenia in older adults: a systematic review and meta-analysis
CONCLUSIONS: Protein-based multinutrient therapy significantly improved HGS, GS, and IGF-1 levels in patients with sarcopenia, but showed no significant effects on SPPB scores, chair-stand time, or SMI. The included studies were generally of high quality, and the results are relatively reliable, however, more high-quality RCTs are needed for further validation.
Fr-AGILE: validation and reliability of a multidimensional and rapid frailty assessment tool in the Turkish elderly population
CONCLUSION: The Fr-AGILE scale is a valid and reliable tool for rapid, multidimensional frailty assessment in older adults. It provides a practical and efficient method for identifying frailty across physical, mental, nutritional, and socioeconomic domains in Turkish geriatric patients.
