BACKGROUND AND PURPOSE Endovascular treatment can improve the outcome of patients treated for ruptured intracranial aneurysms as compared with surgical clipping, but angiographic recurrences are frequent. Endothelial denudation before coil embolization may prevent recanalization and improve results of endovascular treatment. METHODS We compared angiographic and pathological results 3 months a...
Although endothelin-1 (ET-1) is involved in balloon-induced neointima formation, the role of ET-1 in balloon-induced neointima formation in hypercholesterolemia is unclear. In addition, it remains to be determined whether ET-1 is produced by endothelial cells or vascular smooth muscle cells, or both. We investigated tissue immunoreactive ET-1 levels by immunoblot analysis, localization of ET-1 ...
Injury of an artery by passage of a balloon catheter causes both endothelial denudation and medial damage and produces a marked smooth muscle cell (SMC) proliferative response. In this study, the endothelium from rat carotid arteries was removed by use of a rotating loop of 5/0 monofilament suture (gentle denudation technique), which did not cause any detectable damage to the underlying medial ...
Topographic change in regions of active deformation is a function of rates of uplift and denudation. The rate of topographic development and change of an actively uplifting mountain range, the Santa Monica Mountains, southern California, was assessed using landscape attributes of the present topography, uplift rates and denudation rates. Landscape features were characterized through analysis of...
There is functional evidence suggesting that endothelial denudation stimulates inducible nitric oxide synthase (iNOS) activity in the vascular wall. In vitro studies have shown that iNOS expression in smooth muscle cells is reduced by endothelial cells. In the present study we have analyzed the time course of iNOS protein expression in the arterial wall after in vivo deendothelialization. Endot...
