Biomaterial Strategies for Targeted Intracellular Delivery to Phagocytes

Advanced Functional Materials, EarlyView.
Phagocytes are essential to a functional immune system, and their behavior defines disease outcomes. Engineered particles offer a strategic opportunity to target phagocytes, harnessing inflammatory modulation in disease. By tuning features like size, shape, and surface, these systems can modulate immune responses and improve targeted treatment for a ...

Ventricular Standstill in a Patient With a Left Ventricular Assist Device [PDF]

The Annals of Thoracic Surgery, 2019
A 58-year-old woman had medically refractory heart failure due to idiopathic dilated cardiomyopathy. She underwent tricuspid repair and left ventricular assist device implantation for inotropic-dependent heart failure. Because of severe right ventricular dysfunction, she experienced progressive bradycardia and ventricular asystole with ...

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 ...
