The Effect of Silk on the Stabilization of Labile Enzyme Lipoxygenase

open access: yesAdvanced NanoBiomed Research, EarlyView.
Entrapping lipoxygenase within silk significantly extended its stability from under 24 h to 10 days. Variations in silk molecular weight and freeze‐drying conditions influenced silk properties and enzyme interactions. This stabilization is leveraged to develop a linoleic acid electrochemical biosensor, integrating lipoxygenase with horseradish ...

CNC–PNIPAM Drug Delivery System Improves Endometrial Receptivity via Natural Killer Cell Immune Tolerance in Endometriosis

open access: yesAdvanced NanoBiomed Research, EarlyView.
An injectable CNC–PNIPAM hydrogel is developed for intrauterine co‐delivery of levonorgestrel and botropase. This platform reprograms uterine natural killer cells toward an immune–tolerant phenotype and enhances endometrial receptivity marker expression. The results demonstrate a promising strategy to counteract endometriosis–associated infertility and

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

open access: yesThe Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...
