Objective: Endovascular treatment of cerebral aneurysm is safe and effective, but recurrence of disease is frequent compared with results with surgery. The purpose of this study was to determine the effects of recombinant transforming growth factor beta(1) (rTGFbeta(1)) secreted by transplanted autologous vascular smooth muscle cells (VSMC) on results of endovascular treatment.
Methods: VSMC from canine femoral arteries were infected with adenovirus vector encoding rTGFbeta(1)/green fluorescent protein (rTGFbeta(1)/GFP) or GFP only.
Background And Purpose: Coil embolization is safe and effective but may be followed by aneurysm recurrence. Our purpose was to explore the use of alginate as a new embolic agent that could deliver growth factors and improve results of endovascular treatment of aneurysms.
Methods: We first assessed the potential of alginate as a vector for growth factor delivery by using in vitro binding and elution studies.
Monocyte adhesion in diabetic angiopathy: effects of free-radical scavenging.
J Diabetes Complications
October 2003
Increased interaction of monocytes with vascular cells is linked to the development and progression of atherosclerosis in patients with diabetes. One major determinant of increased monocyte binding to vascular cells could be oxidative stress. Given the free-radical scavenging properties of gliclazide, we evaluated the ex vivo and in vitro effects of this drug on human monocyte binding to endothelial cells and smooth muscle cells (SMCs).

The two goals of the present study were to compare results of coil embolization with or without the assistance of an aneurysm neck bridge device (ANBD) and to explore the use of this instrument to control cyanoacrylate embolization.
Methods: Wide necked bifurcation aneurysms were constructed in 28 dogs.
