Targeting age-related LINE-1 activation alleviates cardiac aging
Cardiac aging is a major driver of cardiovascular diseases and associated mortality, yet its therapeutic options are limited. While long interspersed nuclear element-1 (LINE-1) retrotransposons are known to drive cellular senescence, their role in cardiac aging is poorly defined. Here we showed that LINE-1 expression increased in the heart with age. To investigate their role in cardiac aging, we generated cardiomyocyte-specific Mov10-knockout mice, which failed to suppress LINE-1. These mice...
Molecular damage associated with ageing drives inflammation in cardiovascular disease
Chronic inflammation has long been recognized as a major risk factor for and a causal contributor to cardiovascular disease (CVD). However, advances in omics technologies and deepening insights into CVD pathogenesis have expanded our understanding of the underlying mechanisms. Inflammation is now seen not as an isolated cause, but as one of several biological responses to cumulative tissue damage over time. In this Review, we propose that inflammation initially functions as a resilience...
SARC-F and six modified versions: prognostic role for prolonged hospital stay and 1-year mortality in older inpatients
CONCLUSION: Our study demonstrates that all SARC-F-based approaches are linked to prolonged LOS, and almost all approaches were also linked to 1-year mortality. We also introduce the novel (BMI-adjusted) SARC-CalF + MUAC version, pending future validation.
EFFECT OF A NEW PHYTOCOMPASSION ON THE CONTRACTILE ACTIVITY OF LYMPH NODES IN OLD ANIMALS
CONCLUSION: Phytocorrection proved to be effective in stabilizing the structural components of the lymph nodes, which maintained their contractile function at an adequate level. The composition is a geroprotector, and the biologically active substances in the phytocomposition correct and stimulate the lymph nodes' own transport function. Activation of the contractile activity of the lymph nodes is an important link in the body's anti-aging. This phytocorrection may have a wider application.
Myelin is repaired by constitutive differentiation of oligodendrocyte progenitors
Oligodendrocytes form myelin sheaths around axons to enable rapid signaling within neural circuits. The generation of new oligodendrocytes through differentiation of oligodendrocyte precursor cells (OPCs) promotes myelin plasticity and repair in the adult brain. Here, we performed genetic interrogation and in vivo analysis of OPCs in the mouse brain to determine their differentiation dynamics. Our results show that OPCs attempt to differentiate throughout the adult central nervous system with...

Addressing the Aging Workforce Crisis Through Intergenerational Programming: A Retrospective Analysis of Perfect Pair
CONCLUSION: Perfect Pair encourages and prepares college students to pursue a career in aging and engages them in issues associated with aging. This has strong implications for future intergenerational programming that aims to promote workforce development in the aging space.
Lactucopicrin promotes the autophagic degradation of MAP2K4/MKK4 by mediating CCDC50 palmitoylation to alleviate osteoarthritis progression
Macroautophagy/autophagy plays a crucial role in maintaining cellular homeostasis and protecting against osteoarthritis (OA). Its dysregulation contributes to OA progression by promoting chondrocyte senescence, inflammation, and cartilage degradation. Enhancing autophagic activity thus represents a promising therapeutic strategy for OA. In this study, we identified lactucopicrin (LCP) as an effective autophagy activator that alleviates OA progression in a mouse model induced by the...
Follicle-stimulating hormone linked to cognitive decline and amyloid burden in postmenopausal women
INTRODUCTION: Women have a higher risk of developing Alzheimer's disease (AD) than men, with hormonal changes during menopause being a potential factor. However, the exact relationship between these hormonal changes, cognitive function, and AD pathology is not fully understood. This study investigates the differential associations between serum follicle-stimulating hormone (FSH) and estradiol levels with cognitive function and cerebral amyloid-βeta (Aβ) deposition, quantified using amyloid...
Impact of the 2015 Dutch Long-Term Care Reform on Nursing Home Use and Access for People With Dementia
CONCLUSION: Among older Dutch people with dementia, the 2015 Dutch LTC reform was associated with fewer NH admissions and longer waiting lists. While stabilization of the NH admissions may reflect prioritization of persons with dementia within stricter eligibility criteria, the concurrent rise in waiting list prevalence suggests that institutional capacity did not keep pace with persistent need. As a result, many older people with dementia remain longer in the community, raising concerns...
