Sex‐Specific Regulation of Glycemic Homeostasis by Theabrownin from Pu‐erh Tea

Advanced Science, Volume 13, Issue 38, 9 July 2026.
Pu‐erh tea's key component, theabrownin (TB), lowers blood glucose in a sex‐specific manner. In females, estrogen boosts intestinal MUC2 production, which dramatically enhances TB's ability to inhibit the carbohydrate‐digesting enzyme α‐glucosidase.

Asymmetric Dialysis: Truly Unified and Simultaneous Single‐Pass Concentration and Buffer Exchange

Biotechnology and Bioengineering, Volume 123, Issue 7, Page 1814-1824, July 2026.
Asymmetric dialysis, a novel one‐step continuous process combining ultrafiltration and diafiltration, achieves high product concentrations (up to 200 g/L) with low pressures and reduces buffer consumption by 75% compared to conventional methods. This sustainable, low‐cost technology demonstrates significant potential for integration into continuous ...
