Role of lysyl oxidases in neointima development in vascular allografts.
BACKGROUND Extracellular matrix deposition is the main factor inducing stenotic lesions in arterial grafts. Lysyl oxidases (LOX) play a key role in stabilizing collagen and elastin. OBJECTIVE To examine the repair response to arterial allografts in terms of LOX expression and collagen/elastin deposition using LOX inhibitors. METHODS Lewis/Fisher-344 rats were used as donors/recipients. Dono...
متن کاملevaluation of blood hemodynamics in patients with cerebral aneurysm
background: aneurysm is a blood-filled bulge in the wall of vessels that occurred in abdominal aortic and cerebral vessels. the dilation of artery leads to aneurysm. methods: three dimensional modelling was utilized for a patient with cerebral aneurysm and a normal subject, and additional fluid-structural interaction simulation was performed. we consider pulsatile blood velocity as inlet, and b...
متن کاملAneurysm hemodynamics: an experimental study.
PURPOSE To study the flow of blood in aneurysms. METHODS A canine model was used to study the hemodynamics of lateral, bifurcation, and terminal aneurysms with angiography and color Doppler techniques. FINDINGS Flow within experimental aneurysms, although not laminar, is seldom if ever turbulent, but rather is highly predictable, varying primarily according to the relationship of the aneury...

متن کاملComplex hemodynamics at the apex of an arterial bifurcation induces vascular remodeling resembling cerebral aneurysm initiation.
BACKGROUND AND PURPOSE Arterial bifurcation apices are common sites for cerebral aneurysms, raising the possibility that the unique hemodynamic conditions associated with flow dividers predispose the apical vessel wall to aneurysm formation. This study sought to identify the specific hemodynamic insults that lead to maladaptive vascular remodeling associated with aneurysm development and to ide...
