Sexually dimorphic differences in angiogenesis markers are associated with brain aging trajectories in humans
Aberrant angiogenesis could contribute to the development of cognitive impairment and represent a therapeutic target for preventing dementia. However, most studies addressing angiogenesis and cognitive impairment focus on model organisms. To test the relevance of angiogenesis to human cognitive aging, we evaluated associations of circulating blood markers of angiogenesis with brain aging trajectories in a pooled two-center sample from deeply phenotyped longitudinal human cohorts (n = 435; female...
Plasma triacylglycerol length and saturation level mark healthy aging groups in humans
Complex lipids, essential components in biological processes, exhibit conserved age-related changes that alter membrane properties and cellular functions and are implicated as biomarkers and contributors to longevity and age-related diseases. While physical activity alleviates age-related comorbidities and physical impairments, comprehensive exploration of the underlying biological mechanisms, particularly at the level of complex lipids, remains limited. However, clinical studies suggest that...
Slowed epigenetic aging in Olympic champions compared to non-champions
The lifestyle patterns of top athletes are highly disciplined, featuring strict exercise regimens, nutrition plans, and mental preparation, often beginning at a young age. Recently, it was shown that physically active individuals exhibit slowed epigenetic aging and better age-related outcomes. Here, we investigate whether the extreme intensity of physical activity of Olympic champions still has a beneficial effect on epigenetic aging. To test this hypothesis, we examined the epigenetic aging of...
Use of Medications With Somnolence Adverse Effects and Somnolence Symptoms Among Older Adults in the U.S
OBJECTIVES: Nearly half of older adults experience somnolence, but the link between medications with somnolence as an adverse effect and somnolence is unclear. This study investigated the association between polypharmacy and somnolence symptoms (excessive sleepiness or long sleep duration).
