Ascorbic Acid Modulates Collagen Properties in Glucocorticoid‐Induced Osteoporotic Bone: Insights into Chemical, Mechanical, and Biological Regulation

Advanced Healthcare Materials, EarlyView.
Osteoporosis from long‐term glucocorticoid (GIOP) use elevates susceptibility to fracture. This study shows GCs impair ascorbic acid (AA) metabolism in osteoblasts, collagen synthesis and extracellular matrix integrity. AA enhanced collagen biochemical and mechanical properties and restored osteoblast and endothelial function. These findings underscore

Magnetic Resonance Imaging‐Based Quantification of Endosomal Escape Using Iron Oxide Nanoparticle‐Loaded Lipid Nanoparticles

Advanced Healthcare Materials, EarlyView.
The therapeutic efficacy of lipid nanoparticle(LNP)‐based drugs depends on endosomal escape. However, few methods are available for quantifying the efficiency of endosomal escape in vivo. Herein, a novel method for quantifying the endosomal escape efficiency index using magnetic resonance imaging is introduced.

Biocompatible PVDF Nanofibers with Embedded Magnetite Nanodiscs Enable Wireless Magnetoelectric Stimulation in Premotor Cortex

Advanced Healthcare Materials, EarlyView.
Flexible, biocompatible PVDF nanofibers embedded with magnetite nanodiscs enable wireless magnetoelectric neuromodulation. Shape anisotropy of the nanodiscs facilitates magnetostrictive strain transfer under alternating magnetic fields, allowing activation of neurons in vitro and behavioral modulation in vivo, without requiring rigid implants or ...
