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...

Fossils reveal these ancient footbones were robust enough to withstand the impacts of leaping locomotion

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.

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...

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...

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...
