Reassessing the Association of Sedentary Behavior and Physical Activity with Ischemic Stroke: A Mendelian Randomization Study.

Purpose: Findings from previous Mendelian randomization (MR) studies disagreed with the current scientific consensus regarding the role of physical activity (PA) and sedentary behavior in ischemic stroke (IS). We reassessed these associations with a focus on etiological subtypes of IS and the potential mediating roles of cardiometabolic traits and brain imaging-derived phenotypes (IDPs).

Methods: We performed MR analyses using summary statistics from genome-wide association studies of sedentary behavior and PA (n = 88,411~608,595), cardiometabolic traits (n = 393,193~694,649), brain IDPs (n = 33,224) and the latest IS data (62,100 cases and 1,234,808 controls).

Leisure-Time Physical Activity, Sedentary Behavior, and Biological Aging: Evidence From Genetic Correlation and Mendelian Randomization Analyses.

Physical inactivity and sedentary behavior are associated with higher risks of age-related morbidity and mortality. However, whether they causally contribute to accelerating biological aging has not been fully elucidated. Utilizing the largest available genome-wide association study (GWAS) summary data, we implemented a comprehensive analytical framework to investigate the associations between genetically predicted moderate-to-vigorous leisure-time physical activity (MVPA), leisure screen time (LST), and four epigenetic age acceleration (EAA) measures: HannumAgeAccel, intrinsic HorvathAgeAccel, PhenoAgeAccel, and GrimAgeAccel.

Bisphenol S exposure interrupted human embryonic stem cell derived cardiomyocytes differentiation through ER-NF-κB/ERK signaling pathway.

Bisphenol S (BPS) has been put into production as a wide range of Bisphenol A (BPA) alternatives, while little is known regarding its cardiac developmental toxicity. To explore the effect of BPS on cardiomyocyte differentiation and its mechanism, our study established the human embryonic stem cell-cardiomyocyte differentiation model (hESC-CM), which was divided into early period of differentiation (DP1:1-8d), anaphase period of differentiation (DP2:9-16d) and whole stage of differentiation (DP3:1-16d) exposed to human-related levels of BPS. We found that the survival rate of cardiomyocytes was more sensitive to BPS at the early stage of differentiation than at the anaphase stage of differentiation, and exposure to higher than 30 µg/mL BPS throughout the differentiation period decreased the expression of cTnT.
