Impact of Malapposed and Overlapping Stents on Hemodynamics: A 2D Parametric Computational Fluid Dynamics Study

Mathematics, 2021
Despite significant progress, malapposed or overlapped stents are a complication that affects daily percutaneous coronary intervention (PCI) procedures. These malapposed stents affect blood flow and create a micro re-circulatory environment.

Hemocompatible Glycogen‐Tissue Plasminogen Activator Complexes for Enhanced Blood Clot Dissolution

Advanced Healthcare Materials, EarlyView.
Glycogen–heparin‐cRGD nanoparticles enable targeted delivery of tissue plasminogen activator (tPA) to thrombi through activated platelet recognition. The hemocompatible hybrids minimize interactions with blood and immune cells while retaining enzymatic biodegradability.

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

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 ...

Bioinspired Adaptive Artificial Cilia With Tunable Sensitivity and Dynamic Range for Airflow Monitoring in the Central Airway

Advanced Materials Technologies, EarlyView.
A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...
