Cerebral Microvascular Injury and Physical Function in Older Patients With Atrial Fibrillation: Evidence for Sex-Specific Patterns
CONCLUSIONS AND IMPLICATIONS: In older memory clinic patients, AF was associated with sex-specific CSVD patterns: greater WMH burden in men and more microbleeds in women. WMH substantially mediated AF-related decline in physical performance, particularly in men, suggesting that CSVD is an important pathway linking AF to physical dysfunction. These findings underscore the need for sex-specific risk stratification and highlight CSVD as a therapeutic target to preserve physical function in patients...
Exercise Effects on Inflammatory Markers in Middle-Aged and Older Adults: A Network Meta-Analysis
CONCLUSIONS AND IMPLICATIONS: Customized structured exercise effectively reduces age-related low-grade inflammation, especially aerobic and resistance training. These results offer actionable insights for clinicians and policymakers working to improve health outcomes in older adults.
Mechanism and regulation of programmed cell death in aging-related diseases
Aging and its associated diseases are characterized by a complex interplay of cellular dysfunction, chronic inflammation, and tissue degeneration. Dysregulated cell death and the resulting inflammatory responses are pivotal drivers of this pathological synergy. Among various cell demise pathways, programmed cell death (PCD) mechanisms, including apoptosis, necroptosis, and pyroptosis, are critical for maintaining homeostasis but can drive pathology when aberrantly activated. Crucially, they...
Aging of mesenchymal stem cells in bone aging: Mechanisms, impact, and therapeutic perspectives
Aging of the skeleton is a hallmark of organismal decline and underlies prevalent age-related disorders such as osteoporosis and osteoarthritis. Bone marrow-derived mesenchymal stem cells (BMSCs), the primary source of osteoblasts, undergo profound functional deterioration during senescence, leading to an imbalance between bone formation and resorption. This review systematically summarizes the key features of BMSC senescence, including impaired proliferation and differentiation, epigenetic...
From organ age gaps to precision geromedicine: Multi-omic and imaging frameworks for heterogeneous biological aging
Biological aging is increasingly understood as a heterogeneous, multi-system process marked by organ-level vulnerability, cross-organ coordination, and variation in resilience. Advances in plasma proteomics, metabolomics, imaging, DNA methylation, digital biomarkers, and genetic epidemiology have enabled organ-level, system-level, and cross-organ age models, but these measures are often interpreted more strongly than the evidence permits. In this Review, we synthesize evidence on biological age...
SenFlag gene signature identifies senescent cells in mouse and human tissues through a conserved core transcriptional program
Identifying senescent cells via single-cell transcriptome profiling data remains challenging due to cellular heterogeneity and overlap with other cellular states. Here, we present SenFlag, a streamlined gene signature for enhanced identification of senescent cells based on integration of core gene expression features. SenFlag was derived through systematic assessment of bulk and single-cell RNA-sequencing datasets across multiple senescence models. It captures a conserved transcriptional program...
Prevalence and determinants of multimorbidity in older Chinese adults: a nationwide cross-sectional study using CLASS data
CONCLUSIONS: These insights advocate optimizing medical resources, bolstering primary care, and fostering healthy lifestyles to reduce the burden of multimorbidity among older Chinese adults.

Emodin alleviates radiation-induced pulmonary fibrosis by targeting cellular senescence via the mtDNA-cGAS-STING axis
Radiation-induced pulmonary fibrosis (RIPF) is a severe complication of thoracic radiotherapy with limited effective treatment options. Cellular senescence has emerged as a critical driver of age-related tissue fibrosis; however, its role in RIPF and potential as a therapeutic target are underexplored. In this study, we investigated whether emodin, a natural compound with known anti-aging properties, alleviates RIPF by suppressing radiation-induced cellular senescence. In a mouse model exposed...
Impact of mixed reality on the care of the elderly: a scoping review
Population aging requires innovative technological strategies that promote autonomy, functionality, and well-being in old age. In this context, mixed reality (MR), a technology that integrates physical and digital elements in a shared and interactive real-time environment, emerges as a promising alternative. To analyze the current state of evidence on the use of MR in the care of older adults, including its theoretical and practical implications. Scientific articles were reviewed in Scopus, Web...
Emergence of heartbeat frailty in advanced age II: individual cardiovascular aging trajectories revealed by lifelong echocardiography in male mice
Chronological age is the strongest risk factor for cardiovascular disease, yet individual trajectories of cardiovascular aging, particularly during late life, remain incompletely characterized. We performed quarterly echocardiography in 58 male C57BL/6 mice from 6 months until natural death, focusing on long-lived mice surviving beyond the cohort median of 24 months. Progressive body weight loss after 18-21 months defined the frailty transition and partitioned each mouse's lifespan into...
Age-associated neuronal micronuclei formation and transfer to microglia
Microglia, the resident immune cells of the central nervous system, dynamically respond to signals from their microenvironment, including adjacent neurons. Among these signals, nuclear contents released from damaged neurons have been implicated in triggering inflammatory microglial responses. Recently, we found that micronuclei (MNs) derived from neurons during the early postnatal stage act as intercellular mediators that alter the microglial characteristics. However, it remains unclear whether...
Millions may be getting the wrong cholesterol test
A new study suggests that apoB, a blood test that measures harmful cholesterol particles, is better than standard LDL cholesterol testing for deciding who needs more intensive treatment. Researchers found it could prevent more heart attacks and strokes while remaining cost-effective for the U.S. healthcare system.
Scientists found 45 chemicals in pregnant women and many were linked to birth risks
A large study found that pregnant women are exposed to dozens of common chemicals, many of which were associated with earlier births and lower birth weights. Researchers also discovered that some replacement chemicals may be just as concerning as the substances they were designed to replace.
