Social isolation and loneliness are growing public health concerns worldwide; however, the independent and combined associations of change in social isolation and loneliness with mortality are yet to be elucidated. This study aimed to investigate these associations among older adults. This cohort study used data from the Chinese Longitudinal Healthy Longevity Survey, which recruited participants from 2002 to 2011. A total of 8,956 participants aged 65 years and older were included. We used data...

Brown adipose tissue (BAT) protects against obesity, diabetes, and cardiovascular disease. During BAT activation, macroautophagy is inhibited, while chaperone-mediated autophagy (CMA) is induced, promoting thermogenic gene expression, adipokine release, oxidative activity, and lipolysis. Aging reduces BAT function and lowers levels of LAMP2A, the rate-limiting CMA component. Pharmacological CMA activation restores BAT activity in aged mice. To explore the CMA's role in BAT, we generated...

Genome instability is a major factor contributing to cellular senescence. The rRNA gene (rDNA), a repetitive sequence array, is a highly unstable region of the genome. In budding yeast, this instability induces senescence and shortens the lifespan. While the importance of rDNA stability in the aging process is well recognized, the mechanism driving rDNA instability in old cells remains unclear. Using effective methods to isolate old cells in budding yeast, our observations suggest that...

CONCLUSION: The results demonstrate a notable correlation between exposure to heavy metals, specifically lead and cadmium, and the incidence of frailty in U.S. adults aged over 20 years, with a more substantial impact observed in female participants.

Mitochondria play a crucial role in cellular energy metabolism and homeostasis and are strongly implicated in aging and age-related diseases. The outer mitochondrial membrane protein voltage-dependent anion channel (VDAC) plays multiple roles in mitochondrial homeostasis, including transport of metabolites, ATP, and Ca^(2+) Dysregulation of VDAC levels has been associated with cancer, neurodegeneration, metabolic disorders, and aging. Previously, we demonstrated that elevated VDAC-1 levels in...

Transparent conductive oxides (TCOs)-foundation of perovskite solar cells (PSCs)-have long been assumed to be stable, and thus their impact on device longevity is frequently overlooked. Herein, we unveil that fluorine doped tin oxide (FTO) suffers from instability under operational stress, exacerbating PSC stability issue. To address this issue, we propose a universal interface engineering strategy employing a scalable thermal evaporation followed by natural oxidation to form an atomically...

CONCLUSION: By analyzing the structure, strength, and interaction path between IC and FA, research has found that diseases are just a process of FA development. However, the source variable - patient's IC - has received less attention. This suggests that policymakers should not only focus on identifying a disease, but also on assessing, maintaining, and providing intervention before the disease. The authorities should also promote the implementation of people-centered rather than...
