Measurements of urinary adrenal corticoid excretions have been widely used for the evaluation of adrenal hormone production and degradation. The possibility that renal dysfunction may alter the urinary excretion of these substances is generally ignored. The present study was done in experimental animals in which controlled acute unilateral alterations of renal hemodynamics were produced during ...

Three patients with vertebrobasilar junction aneurysms and associated fenestration were treated with Guglielmi detachable coils. The structure and hemodynamics of fenestrations may account for their frequent association with aneurysms. The complex hemodynamics of these aneurysms requires evaluation of both vertebral arteries. One treatment complication occurred but resulted in no deficit. All p...

In the present study, we investigate the hemodynamics inside left atrium (LA) and understand its impact on the development of ventricular flow patterns. We construct the heart model using dynamic-computed tomographic images and perform simulations using an immersed boundary method based flow solver. We show that the atrial hemodynamics is characterized by a circulatory flow generated by the lef...

Skin is a highly structured tissue, raising concerns as to whether skin pigmentation due to epidermal melanin may confound accurate measurements of underlying hemodynamics. Using both venous and arterial cuff occlusions as a means of inducing differential hemodynamic perturbations, we present analyses of spectra limited to the visible or near-infrared regime, in addition to a layered model appr...

Hemodynamics is recognized as a relevant factor in the development and rupture of cerebral aneurysms, so further studies related to different physiological conditions human represent an advance understanding pathology risk. In this paper, Fluid-structure interaction simulations (FSI) were carried out six models order study hemodynamics effects isolated systolic hypertension (ISH) condition comp...

While the mechanisms of plaque development in coronary arteries are not yet completely understood, vessel geometry and its influence on hemodynamics are of major importance. This manuscript presents an overview on our method for spatio-temporal modeling of the coronary arteries by fusion of data from x-ray angiography and intravascular ultrasound (IVUS) and elaborates on the aspects of 4-D comp...
