Bioresorbable Scaffolds for Coronary Arteries: Where Do We Stand Today?

VIEW Medicine, Volume 1, Issue 1, November 2026.
Bioresorbable coronary scaffolds are moving from thick strut pitfalls to thinner, stronger, healing‐oriented designs. Integrating advances in materials, guided implantation with preparation, size, and postdilation steps, and resorption aligned to healing, we synthesize clinical evidence and chart a roadmap toward intelligent, transient platforms ...

Synergistic Enhancement of Mechanical and Electrical Properties and Corrosion Resistance of Graphene‐Copper Composites by Accumulative Roll Bonding

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Graphene‐reinforced copper (Gr/Cu) composites have attracted considerable attention because of their potential to achieve a synergistic enhancement of strength, electrical conductivity, and corrosion resistance; however, the poor dispersion of graphene in the Cu matrix remains a key limitation for their further development.

Impact of geometric factors and shear stress on endothelial function: Hemodynamic insights from human cerebral arterial bifurcations

Physiological Reports, Volume 14, Issue 11, June 2026.
Abstract Vascular inflammation is not a random biological event but rather a process that is strictly regulated by physical forces. While biochemical mediators are well characterized, the local physical mechanisms that predispose specific cerebral vascular sites to inflammation, specifically the geometry of arterial bifurcations, remain ...
