Structural Motifs in Soft Fibrous Tissues: Revealing Structure‐Mechanics Relationships in Deformation and Tear Resistance for Biomimetic Material Design

Advanced Healthcare Materials, EarlyView.
This review explores how soft fibrous tissues achieve their remarkable mechanical behavior through recurring structural motifs across multiple length scales. It highlights key advances in mimicking these features using fiber‐reinforced hydrogels and hierarchical composites, offering insights into mechanical compatibility, flaw tolerance, and tear ...

Aortic Valve Replacement

The Journal of ExtraCorporeal Technology, 1990
Indications for aortic valve replacement can be summarized into two disease processes, moderate to severe aortic stenosis (with or without symptoms) and moderate to severe aortic insufficiency. Fortunately, standards of care differ with each physician and so indications for aortic valve replacement are not clearly defined. To understand how the surgeon

Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

Advanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...
