Targeting NRP1 in Endothelial Cells Facilitates the Normalization of Scar Vessels and Prevents Fibrotic Scarring

Advanced Science, EarlyView.
Scars exhibit vascular abnormal alterations, including upregulated NRP1 expression in endothelial cells, increased vascular density and branching, compromised vessel wall integrity, and incomplete pericyte coverage. Therapeutic targeting of NRP1 through hydrogel spray delivery offers a promising approach to normalize aberrant vasculature and prevent ...

A Microfluidic Digital Shutter of Liquid–Liquid Interface for Fabrication of Multifaceted Hydrogel Microfiber Structure

Advanced Science, EarlyView.
A programmable passive digital shutter based on multiphase liquid–liquid interface dynamics is introduced for precise fabrication of hydrogel microfibers. By modulating the shutter operation, microfibers with tunable geometry—including linear, helical, tadpole‐like, and spherical forms—are produced.

A Virtual Clinical Trial of Psychedelics to Treat Patients With Disorders of Consciousness

Advanced Science, EarlyView.
Disorders of consciousness after severe brain injury are marked by reduced complexity of brain activity and limited treatment options. Using personalized whole‐brain models, this study shows that simulated lysergic acid diethylamide (LSD) and psilocybin shift patient brain dynamics closer to criticality.

Quantifying Additive Manufacturing Vapor Plumes Using Laser‐Induced Breakdown Spectroscopy, Synchrotron X‐Ray Radiography and Simulations

Advanced Science, EarlyView.
This study presents a novel in situ laser‐induced breakdown spectroscopy system for monitoring metal vapors produced by the intense laser‐metal interactions in laser powder bed fusion additive manufacturing and laser welding. The insights from this new technique reveal changes in alloy compositions and provide the first in situ validation of multi ...
