Increased Expression of Interleukin-18 mRNA is Associated with Carotid Artery Stenosis

Balkan Medical Journal, 2018
Background: Carotid artery stenosis is the atherosclerotic narrowing of the proximal internal carotid artery and one of the primary causes of stroke. Elevated expression of the pleiotropic proinflammatory cytokine interleukin-18 has been demonstrated in ...

Programmable Compliance in Small‐Diameter Vascular Grafts by Design of Melt‐Electrowritten Scaffold Architectures for In Situ Tissue Engineering

Advanced Healthcare Materials, EarlyView.
Small‐diameter vascular grafts with compliance tunable by design are fabricated via melt electrowriting. By controlling the winding angle of intertwined helical fibers, grafts with compliances matching those of human vessels, from veins to arteries, are realized. This holds the potential of avoiding a compliance mismatch, which has been identified as a

A Patient‐Specific 3D Printed Carotid Artery Model Integrating Vascular Structure, Flow, and Endothelium Responses

Advanced Healthcare Materials, EarlyView.
This study introduces the first miniaturized, patient‐specific carotid artery model created via 3D printing using GelMA with embedded vascular cells. Combining CFD, PIV, and flow perfusion, the model replicates anatomically dependent hemodynamics and cellular responses.

Plasma‐Polymerized Nanoparticles Presenting Fibrillin‐1 Drive Rapid Re‐Endothelialization of Vascular Grafts

Advanced Healthcare Materials, EarlyView.
Commercial vascular grafts are made from ePTFE, a highly hydrophobic, foreign material that fails at a high rate in small‐diameter applications. Plasma polymer nanoparticles (PPN) are a versatile material functionalisation tool, used here to present fibrillin‐1 fragment PF8 on the graft surface.
