Retrotransposable elements (RTEs) are interspersed repetitive sequences that represent a large portion of eukaryotic genomes. Ancestral expansions of RTEs directly contributed to the shaping of these genomes and to the evolution of different species, particularly mammals. RTE activity is tightly regulated by different epigenetic mechanisms but this control becomes compromised as cells age and RTEs are reactivated. This dysregulation of RTEs leads to perturbation of cell function and organ and...

CONCLUSIONS: High-quality trials are needed to clarify the neurobiological impact of music-making, particularly in MCI populations.

This study aimed to investigate the relationship between total antioxidant capacity (TAC) and phenotypic age acceleration (PhenoAgeAccel), a measure of accelerated biological aging, using data from the National Health and Nutrition Examination Survey (NHANES). Data from the 2003-2010 NHANES surveys, encompassing 16,395 participants, were analyzed. Principal component analysis (PCA) was used to reduce data dimensionality. Multivariate logistic regression models were employed to evaluate the...

CONCLUSIONS: Our findings suggest that PA is associated with a better health-related QOL. However, no association was observed between PA and psychological well-being in this population. We found that calisthenics were the most commonly performed and that more physically active older adults performed several types of exercises/sports in addition to calisthenics and walking for longer durations. Since few studies have investigated the types of exercises/sports in this age group, these findings...

The number of patients requiring dialysis therapy continues to increase worldwide because of the lack of effective treatments for chronic kidney disease (CKD). Furthermore, no curative treatments for acute kidney injury (AKI) have been established. The therapeutic effects of human induced pluripotent stem cell-derived nephron progenitor cells (hiPSC-NPCs) on AKI have been reported in mice but not clinically confirmed. There are also no reports examining the therapeutic potential of hiPSC-NPCs on...

CONCLUSIONS: In cohort studies conducted in the United States and Europe, greater wealth was associated with lower mortality, and the association between wealth and mortality appeared to be more pronounced in the United States than in Europe.
