Restenosis is an adverse outcome of angioplasty, characterized by vascular smooth muscle cell (VSMC) hyperplasia. However, therapies targeting VSMC proliferation delay re-endothelialization, increasing the risk of thrombosis. Resveratrol (RESV) inhibits restenosis and promotes re-endothelialization after arterial injury, but in vitro studies assessing RESV-mediated effects on endothelial cell g...

The main way of treating symptomatic atherosclerosis is angioplasty with stent placement. This intervention injures the vascular wall, causing endothelial loss, inflammation and intimal hyperplasia (IH), which frequently cause restenosis, a de novo obstruction of the lumen. To prevent this complication, Drug Eluting Stents have been coated with antiproliferative agents. Although they have prove...

OBJECTIVE Laminar shear stress is atheroprotective for endothelial cells (ECs), whereas nonlaminar, disturbed, or oscillatory shear stress correlates with development of atherosclerosis and neointimal hyperplasia. The effects of orbital and laminar shear stress on EC morphology, proliferation, and apoptosis were compared. METHODS ECs were exposed to orbital shear stress with an orbital shaker...

background and objective: vascular endothelial growth factor (vegf) and its receptors (vegf-r1 and r2) are major regulators of angiogenesis. this study was designed to assess serum levels of vegf and vegf-r1 and their prognostic significance in newly diagnosed childhood acute leukemia. materials and methods: for this purpose, vegf and vegf-r1 were determined using enzyme linked immuno-sorbant a...
