A Magneto‐Mechanically Activated Nerve Guidance Conduit Promotes Peripheral Nerve Regeneration via TIMP1‐Mediated Membrane Tension Transfer

Advanced Functional Materials, EarlyView.
This study presents a magneto‐mechanical strategy that incorporates FP@MSCs into an aligned PCL/GelMA nerve guidance conduit. Magnetic stimulation increases membrane tension in FP@MSCs, triggering cytoskeletal remodeling, Schwann cell‐like differentiation, and TIMP1 secretion. TIMP1 activates ITGB1/CD63–FAK signaling in NE‐4C cells, increasing membrane

Bioinspired Hydrogels with Broadly Programmable Mechanics for Soft‐Tissue Interfaces

Advanced Functional Materials, EarlyView.
Sea cucumber‐inspired gelatin hydrogels are formed by directional freezing and mechanically programmed through subsequent ionic treatment. Multiscale characterization and modeling link ion‐regulated chain interactions to directional load transfer within the aligned hierarchical architecture.

Patency of arteriovenous fistulas in hemodialysis in French Guiana: influence of vascular flow, climate and clinical factors

BMC Nephrology
Introduction Arteriovenous fistula (AVF) is the preferred access for hemodialysis. Achieving one-year patency is crucial to avoid dependence on central venous catheters, which carry significant risks of infection and thrombosis.

Engineering Concentration‐Dependent Intravitreal Mobility via Cyclic Arginine‐Enriched Nanocarrier Surface Modification: In Vivo Proof‐of‐Concept in a Porcine Large Animal Model

Advanced Healthcare Materials, EarlyView.
In this study, Hammer et al. highlight cyclic‐arginine surface engineering as a highly biocompatible, controllable, and concentration‐dependent regulator of intravitreal nanoparticle mobility in vivo in a translational large animal model. The cyclic arginine surface‐modification supports the development of next‐generation biomaterials for long‐acting ...

A bio-inspired screwed small-diameter vascular graft for endotheliazation and arterial regeneration

Bioactive Materials
The frequent failures of small-diameter vascular grafts (SDVGs) mainly result from thrombosis and insufficient endothelialization. Despite recent biochemical modification strategies aiming to enhance long-term patency, the challenges of suppressing ...

Regulation and Maintenance of Vascular Tone and Patency in Cardiovascular Health and Disease

International Journal of Vascular Medicine, 2012
Despite numerous advances in health care practices, cardiovascular disease still remains the leading cause of morbidity and mortality worldwide. Perhaps the most important consequence of cardiovascular disease is the interruption of blood flow to organs such as the heart and brain, resulting in the clinical presentation of a heart attack or stroke.
