Why do ulcerated atherosclerotic carotid artery plaques embolize? A flow dynamics study.
PURPOSE We describe and analyze flow dynamics and pressure relationships in an ulcerated atherosclerotic human carotid bulb. METHODS Replicas of an ulcerated atherosclerotic human carotid bulb were created using the lost wax technique. The resulting replicas were placed in a circuit of pulsating non-Newtonian fluid and flows were adjusted to replicate human physiological flow profiles. Common...
متن کاملExperimental carotid occlusion: funduscopic and fluorescein angiographic findings.
A characteristic fundus picture was consistently produced following acute bilateral common carotid artery ligation in mature rats, reminiscent of human carotid occlusive disease. Two days after ligation it consisted of dilatation and tortuosity of retinal veins, blurring and swelling of the optic disc, retinal whitening primarily along the venous distribution, and straightening of retinal arter...
متن کاملWhy Minimax Works: An Alternative Explanation
In game-playing programs relying on the minimax principle, deeper searches generally produce better evaluations. Theoretical analyses, however, suggest that in many cases minimaxing amplifies the noise introduced by the heuristic function used to evaluate the leaves of the game tree, leading to what is known as pathological behavior, where deeper searches produce worse evaluations. In most of t...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولUlcerated atheromatous plaques of the carotid artery bifurcation.
Ulcerated A theromatous Plaques of the Carotid A rtery Bifurcation • The clinical diagnosis of an ulcerated plaque at the bifurcation of the common carotid artery is based on: mid-carotid bruit, cholesterol or platelet emboli in the retina, transient ischemic attacks particularly with amaurosis fugax, and a reversible neurological deficit. In this series, thrombosis in situ was the final phenom...
