HYPOTHESIS The factors affecting blood flow within the hypervascular thyroid gland and the effect of vascularization on the preparation for thyroidectomy as treatment for Graves disease can be documented. DESIGN Blood flow through the superior thyroid arteries of patients with Graves disease, maintained in a euthyroid status, was measured by color flow Doppler ultrasonography. The microvessel...

We developed a rat model of pulmonary arteriovenous malformations after cavopulmonary anastomosis. We sought to determine whether this model reproduces the angiographic and histologic features seen in the human condition. Eight Sprague-Dawley rats underwent a right superior cavopulmonary anastomosis with the use of microsurgical techniques. Between 2 and 13 mo, pulmonary angiography was perform...

Elevated nitric oxide (NO) and endothelial nitric oxide synthase (eNOS) have been observed in cancer patients in malignancy state. We hypothesize that the higher NO production in the microvessels of these patients attracts more tumor cells (TCs) to adhere and accomplished their metastases. Since there are tens to hundreds of endothelial cells (ECs) forming on the microvessel walls, it is unsust...

Angiotensin II is known to stimulate angiogenesis in the peripheral circulation through activation of the angiotensin II type 1 (AT1) receptor. This study investigated the effect of angiotensin receptor blockade on cerebral cortical microvessel density. Rats (6-7 wk old, n = 5-17) were instrumented with femoral arterial and venous indwelling catheters for arterial blood pressure measurement and...

Background-Pericytes represent a unique subtype of microvessel-residing perivascular cells

statement of problem: candidal colonies make up a part of natural oral flora and are considered as predisposing factors for opportunistic infections. since hemodialysis leads to body immune suppression and make patients susceptible to opportunistic infections, it is useful to investigate the relationship between hemodialysis and such infections.purpose: the aim of the present research was to st...
