Nicotine Reprograms Aging‐Related Metabolism and Protects Against Motor Decline in Mice

open access: yesAdvanced Science, EarlyView.
Long‐term oral nicotine intake protects against age‐related motor decline in mice without eliciting systemic toxicity. Integrated multi‐organ metabolomic profiling and longitudinal gut microbiota analyses reveal that nicotine induces coordinated remodeling of glycolipid and sphingolipid metabolism, enhances NAD⁺ bioavailability, and suppresses ceramide

Enhanced Activities of OCT4 and SOX2 Promote Epigenetic Reprogramming by Shortening G1 Phase

open access: yesAdvanced Science, EarlyView.
Fusing the VP16 domain to OCT4 and SOX2 (OvSvK) enhances iPSC generation by activating downstream targets, including those regulating the cell cycle. This accelerates reprogramming by shortening the G1 phase and reducing H3K27me3 levels. Modulating Ccnd1, Cdkn2a, and Ccne1 improves efficiency, linking cell cycle to epigenetic remodeling.

Microporous Polymer Membranes: Molecular Stents Enhanced Solvent‐Accessibility for Organic Solvent Transport

open access: yesAdvanced Science, EarlyView.
A novel microporous polyimide (PI‐TB‐NDI) is designed for enhanced organic solvent nanofiltration. By incorporating o‐methyl groups into the Tröger's base (TB) unit to create molecular stents, the polymer's intrinsic free volume is effectively increased without the need for post‐treatment.

Exosomes From Intestinal Epithelial Cells Promote Hepatic Differentiation of Liver Progenitor Cells in Gut‐Liver‐on‐a‐Chip Models

open access: yesAdvanced Science, EarlyView.
The effects of intestinal epithelial cells and their exosomes on the hepatic differentiation of HPCs are explored in a gut‐liver‐on‐a‐chip. Exosomes from intestinal epithelial cells improve liver fibrosis. Moreover, the miR‐371‐373 cluster in the exosomes may mediate this effect by regulating the hepatic differentiation of HPCs.

Effects of vitamin E supplementation in the extender on frozen-thawed bovine semen preservation

open access: yesAnimal, 2011
The maturing sperm cells discard the majority of their cytoplasm during the final stages of spermatogenesis and lose some of their defense enzymes. The purpose of this study was to investigate the effects of vitamin E supplementation on standard semen ...
