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

open access: yesAdvanced 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 ...

Stent thrombosis and drug-eluting stents [PDF]

open access: yesJournal of Cardiology, 2011
Coronary stents have been used for the treatment of patients with coronary artery disease (CAD), and significantly improved procedural safety and are associated with a lower rate of restenosis compared with balloon angioplasty alone. Drug-eluting stents (DES) have been dominant for the treatment of CAD with efficacy in significantly reducing both ...
