Pressure‐Assisted Drug Delivery Using High‐Pressure Balloon Platform Improves Vascular Drug Penetration and Anti‐Restenotic Effects

Advanced Healthcare Materials, EarlyView.
A dual‐layer high‐pressure drug‐coated balloon (HP@DCB) increased balloon‐wall contact and promoted deeper paclitaxel (PTX) penetration than a conventional noncompliant DCB. In in vivo study, HP@DCB treatment improved luminal patency and reduced neointimal hyperplasia, supporting pressure‐assisted drug delivery as a promising strategy for enhancing the

A novel protocol for the characterization of ureteral stent echogenicity

BMC Urology
Background Decreasing radiation exposure in renal colic management involves revisiting diagnostic, intraoperative, and postoperative practices. One approach is a shift in procedural standards from intraoperative fluoroscopy to ultrasonography.

Rubber‐Glass‐Crystal Triple Phase Transition in Polyacrylamide Hydrogels and Environment‐Adaptive Shape Memory Effect

Advanced Materials Interfaces, EarlyView.
By analyzing the thermal‐mechanical properties and molecular‐scale interactions in polyacrylamide (PAAM) hydrogels, this research demonstrates a rubber‐glass‐crystal phase transition under the combined stimuli of temperature and moisture. Because of these hybrid phase transitions, PAAM hydrogels exhibit shape memory behavior in thermal and moist ...

Scalable Fabrication of Chemically Stabilized Gelatin Hydrogel Fibers by Thermal Drawing

Advanced Materials Interfaces, EarlyView.
Scalable processing of hydrogel fibers remains a major challenge. By coupling thermal drawing with Maillard chemistry, a transient viscous‐flow window is created that enables continuous fabrication of microstructured gelatin fibers tens of meters long, while continued in situ crosslinking during drawing stabilizes the fibers for physiological ...
