CONCLUSION: According to the relatively high prevalence of mild cognitive impairment in geriatric population, determination of proper health strategies seems necessary for diagnosis and treatment of mild cognitive impairment along with awareness and management of associated consequences in geriatric population.

CONCLUSION: The LC9 score represents an important advancement in assessing mortality risk among frail older adults. This study highlights the need for holistic approaches in aging health assessments and suggests that integrating mental health within cardiovascular metrics may enhance the accuracy of risk predictions.

Specialized intramembrane proteases, known as iCLiPs, regulate the processing of transmembrane proteins by releasing intracellular domains, which can function as transcriptional regulators. The signal peptide peptidase-like (SPPL) family of iCLiPs, particularly SPPL2b, has roles in immune regulation, neuronal function, and disease pathogenesis. In the brain, SPPL2b localizes mainly in the plasma membrane of neurons and microglia and is abundant in the cortex and hippocampus. Its known substrates...

Lifespan is an integrative phenotype whose genetic architecture is likely to highlight multiple processes with high impact on health and aging. Here, we conducted a genetic mega-analysis of longevity in Diversity Outbred (DO) mice that included 2,444 animals from three independently conducted lifespan studies. We identified eight loci that contributed significantly to lifespan independently of diet and drug treatment in at least one study. One of these loci also influenced lifespan in a...

Cellular senescence is a multifaceted process involving cell cycle arrest, telomere shortening, and the accumulation of DNA damage associated with aging and cellular stress. It is marked by persistent cell cycle arrest and DNA damage accumulation, and plays an increasingly recognized role in age-related diseases and cancer therapy. Olaparib, a poly (ADP-ribose) polymerase (PARP) inhibitor, is approved for use in ovarian cancer treatment. We hypothesized that olaparib may influence senescence by...
