Balance training improves postural control and performance-related prefrontal brain activation in healthy older adults: Results of a six-month randomized controlled training intervention
Age-related deterioration in postural control is an important factor decreasing quality of life. Functional neuroimaging studies have shown that the activation of the prefrontal cortex (PFC) during balancing is typically higher in older (OA) compared to younger adults (YA), probably reflecting a mechanism contributing to worsened balance control with aging. Here, we hypothesized that balance training (BAL) shifts PFC activation towards a more efficient pattern, enabling improved balance...
Identifying lifestyle risk factors that discriminate memory trajectories: Differential findings across racial and ethnic groups in older adults
INTRODUCTION: Differences in lifestyle factors contribute towards inequalities in dementia incidence and memory trajectories across racial and ethnic groups. We identifieded lifestyle risk factors that best discriminat memory trajectories in older adults without cognitive impairment.
Multi-omics strategies to decode the molecular landscape of cellular senescence
Cellular senescence is a conserved cellular program characterized by a permanent cell cycle arrest triggered by a variety of stressors. Originally described as a tumor-suppressive mechanism, it is now recognized to exert pleiotropic and context-dependent functions, contributing to key physiological processes such as embryogenesis and tissue repair, as well as to processes associated with aging and the development of age-related diseases. Unlike normal cells, senescent cells remain metabolically...
A physically and mentally active lifestyle relates to younger brain and cognitive age
Resistance to age-related pathological changes (brain maintenance), including Alzheimer's disease, cerebrovascular disease, and neurodegeneration may promote cognitive resilience in aging. However, how lifestyle and health profiles relate to successful cognitive and brain aging remains poorly understood. In a novel, deeply phenotyped cohort of 211 cognitively unimpaired older adults (age = 71.0 ± 7.4 years, 46% female), we characterized principal components of lifestyle and health using...
Association between the healthy eating index and sarcopenia in Chinese elderly: a cross-sectional study
CONCLUSION: Better diet quality, reflected by higher HEI scores, is associated with a lower prevalence of sarcopenia in older adults, highlighting the importance of nutrition in preventing sarcopenia.
The therapeutic potential of adiponectin and extracellular vesicles for promoting improved healthspan
The gradual decline in physiological functions that comes with aging contributes to a range of chronic diseases, such as Alzheimer's, type 2 diabetes, heart failure, and osteoarthritis. Significant advancements in human longevity due to socioeconomic development have resulted in a foreseeable and substantial strain on the global healthcare system. In fact, there is now a shift in research focus towards enhancing healthspan. As a result, the development of improved therapies for various chronic...
Two-year changes in hippocampal subfield volumes are age-dependent across the lifespan
The hippocampus (Hc), which is crucial for memory across the lifespan, is comprised of distinct subfields: dentate gyrus (DG), Cornu Ammonis (CA) sectors 1-3, and subiculum. Cross-sectional studies show that Hc subfield volumes exhibit a differential association with age across the lifespan. However, the evidence of age-related changes and individual variability in developmental trajectories is sparse. We examined changes in Hc subfield volumes in a large normative lifespan sample (N = 474 at...

Exploring age-related iron dysregulation: effects on longevity, body size, and behavior in C. elegans
Age-related iron accumulation is widely observed in various species and significantly impacts physiological processes. However, systematic investigation into how age-related iron dysregulation affects different life traits is still limited. This study utilizes the model organism C. elegans to examine the roles of iron regulatory genes throughout different life stages, focusing on their effects on iron homeostasis, longevity, mobility, size, and mechanosensation. Our expression analysis indicated...
Multiomics and cellular senescence profiling of aging human skeletal muscle uncovers Maraviroc as a senotherapeutic approach for sarcopenia
Cellular senescence is a hallmark of organismal aging but how it drives aging in human tissues is not fully understood. Here we leverage single nucleus multiomics to profile senescence in mononucleated cells of human skeletal muscle and provide the first senescence atlas. We demonstrate the intra- and inter-populational transcriptomic and epigenomic heterogeneity and dynamics of cellular senescence. We also identify commonalities and variations in senescence-associated secretory phenotypes...
