Ultrasonic Atomization Spray Coating of PCL on an Mg‐Based Alloy Enhanced by Plasma Electrolytic Oxidation for Improved Adhesion, Corrosion Resistance, and Biocompatibility

Advanced Engineering Materials, EarlyView.
Plasma electrolytic oxidation is combined with ultrasonic spray deposition of polycaprolactone (PCL) on WE43 magnesium alloy to improve adhesion, corrosion resistance, and cytocompatibility. The hybrid coating demonstrates significantly reduced hydrogen evolution and enhances mechanical bonding, offering a promising strategy for next‐generation ...

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

Advanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Novel Drug‐Testing Platform for Vascular Injury‐induced Intimal Hyperplasia Using a Microphysiological System

Advanced Healthcare Materials, EarlyView.
This study develops a 3D vascular injury model using a microphysiological system that mimics key features of intimal hyperplasia. Antiproliferative drugs reduced VSMC proliferation but worsened endothelialdenudation. A combination of diphenyleneiodonium and quercetin effectively reduced proliferation and migration of VSMC and inflammation while ...

Restenosis after directional coronary atherectomy

Journal of the American College of Cardiology, 1992
This study evaluates the incidence of restenosis after successful directional coronary atherectomy and identifies risk factors for restenosis.Directional coronary atherectomy has been shown to be a safe and effective treatment of obstructive coronary artery disease; however, information regarding restenosis is limited.Between October 1986 and December ...

Everolimus‐Coated Laser‐Cut Self‐Expandable Metallic Stent Suppresses Stent‐Induced Tissue Hyperplasia in a Rat Gastric Outlet

Advanced NanoBiomed Research, EarlyView.
Everolimus‐coated laser‐cut self‐expandable metallic stents suppress stent‐induced tissue hyperplasia in the gastric outlet by reducing inflammation, fibrosis, and smooth muscle proliferation. Herein, we demonstrate the mechanical stability, sustained drug release, and histological benefits in a rat gastric outlet model, suggesting potential for ...

Gene Polymorphisms of the Renin-Angiotensin-Aldosterone System as Risk Factors for the Development of In-Stent Restenosis in Patients with Stable Coronary Artery Disease

Biomolecules, 2021
This study investigated the renin-angiotensin-aldosterone system (RAAS) gene polymorphisms as possible genetic risk factors for the restenosis development in patients with drug-eluting stents.

Experimental models of coronary artery restenosis

Journal of the American College of Cardiology, 1992
The study of potentially effective drug therapies and mechanical devices for the prevention of restenosis after percutaneous coronary revascularization has relied heavily on the use of experimental animal models. To date, greater than 50 experimental studies have been reported and have suggested that at least nine different classes of pharmacologic ...

MEW/PVA‐MA Hydrogel Vascular Grafts: Enhancing Hemocompatibility and Endothelialization

Advanced NanoBiomed Research, EarlyView.
A biomimetic vascular graft combining biofunctionalized PVA‐MA hydrogels with a MEW scaffold is developed for small‐diameter applications. Gel‐MA and Hep‐MA incorporation enhances endothelialization and hemocompatibility, respectively, targeting the acute biological responses.

Restenosis pathophysiological mechanisms and genetic markers after percutaneous coronary interventions

Кардиоваскулярная терапия и профилактика, 2007
Coronary restenosis remains the main problem for effectiveness of percutaneous transluminal coronary angioplasty (PCA) and coronary stenting (CS). The aim of this review is to analyze pathogenetic mechanisms of coronary restenosis after PCA and CS, as ...

Use of drug-coated balloon instead of drug-eluting stent for pediatric cardiac allograft vasculopathy

Annals of Pediatric Cardiology, 2023
Cardiac allograft vasculopathy (CAV) sometimes leads to restenosis, even after percutaneous transcatheter intervention. Recently, drug-coated balloons (DCBs) have been successfully used to treat coronary artery disease, especially CAVs, in adults ...
