Vitamin C conveys geroprotection on primate ovaries

1 month 2 weeks ago
Ovarian aging plays a pivotal role in female reproductive health, with implications for treatment strategies and quality of life. However, the potential of a single pharmaceutical agent to mitigate primate ovarian aging remains largely unexplored. Our 3.3-year study in monkeys demonstrates that oral vitamin C has geroprotective effects against ovarian aging. Vitamin C diminishes key aging biomarkers, including oxidative stress and follicular depletion. Using a single-cell transcriptomic clock,...

BACKGROUND: For more than three decades, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) has provided a framework to quantify health loss due to diseases, injuries, and associated risk factors. This paper presents GBD 2023 findings on disease and injury burden and risk-attributable health loss, offering a global audit of the state of world health to inform public health priorities. This work captures the evolving landscape of health metrics across age groups, sexes, and...

Global age-sex-specific all-cause mortality and life expectancy estimates for 204 countries and territories and 660 subnational locations, 1950-2023: a demographic analysis for the Global Burden of Disease Study 2023

1 month 2 weeks ago
BACKGROUND: Comprehensive, comparable, and timely estimates of demographic metrics-including life expectancy and age-specific mortality-are essential for evaluating, understanding, and addressing trends in population health. The COVID-19 pandemic highlighted the importance of timely and all-cause mortality estimates for being able to respond to changing trends in health outcomes, showing a strong need for demographic analysis tools that can produce all-cause mortality estimates more rapidly with...
