Effect of Flushing Diets With Different Omega‐6 to Omega‐3 Fatty Acids Ratios on Reproductive Performance and Blood Biochemical Attributes in Shall Ewes

open access: yesVeterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Dietary supplementation with different omega‐6:omega‐3 fatty acid ratios influenced ovarian activity, reproductive hormones and fertility outcomes in Shall ewes under semiarid conditions. Ewes receiving the lower ω6:ω3 ratio (1.5) showed improved follicular dynamics, higher progesterone levels and enhanced conception rate compared with higher ratios ...

Self‐Organizing Ovarian Somatic Organoids Preserve Cellular Heterogeneity and Reveal Cellular Contributions to Ovarian Aging

open access: yesAging Cell, Volume 25, Issue 1, January 2026.
We report the development and application of a mouse ovarian somatic organoid model to elucidate a fundamental new understanding of the cell biology of the aging ovarian microenvironment. ABSTRACT Ovarian somatic cells are essential for reproductive function, but no existing ex vivo models recapitulate the cellular heterogeneity or interactions within ...

Enhanced Selenium Supplement Extends Lifespan and Delays Multi‐Organs Aging by Regulating the Sik1 Pathway Through Maintaining Calcium Homeostasis

open access: yesAdvanced Science, Volume 12, Issue 47, December 18, 2025.
Aging involves physiological decline and heightened disease susceptibility, necessitating effective interventions. Redox‐responsive selenium‐loaded nanoparticles (SeMSNs) are developed, which delay cellular senescence by reducing oxidative stress and senescence markers (p16/p21). In aged mice, SeMSNs extend lifespan, improve organ function, and restore
