The current technology used in imaging has an increasing role medical education. concept of using image analysis programme to help estimating the age aorta, largest artery, can be clearly seen use, especially establishing changes for identification individuals. purposes study were investigate gross morphology, morphometric parameters, and correlation between parameters with aorta human cadavers...

1. It has been reported that ortreotide partially corrects the hyperdynamic state in patients and animals with portal hypertension. The aim of the present study was to investigate whether chronic administration of octreotide can increase vascular responsiveness in rats with portal hypertension. 2. Portal hypertension was induced by partial portal vein ligation. Octreotide was given for 9 days s...

The aim of this study was to anatomically verify echo-guided identification of key lumbar arteries supplying blood to the spinal cord and to examine whether changes in nerve root motion could be used for detecting malperfusion following aortic cross-clamping. In two beagle dogs, nerve root motion was monitored through the intervertebral disc using transesophageal echocardiography. Communication...

Peripheral (brachial) pulse pressure normally exceeds central (aortic) pulse pressure but is a less powerful predictor of cardiovascular risk. The difference between the 2 variables, called pulse pressure amplification, has never been specifically studied between the proximal and distal aorta in coronary patients. Our goal was to determine aortic pulse pressure amplification in subjects at high...

OBJECTIVE This study was designed to examine why in WHHL rabbits, muscular arteries, such as the carotid artery, are relatively resistant to atherosclerosis compared with the aorta, with a special reference to monocyte chemoattractant protein (MCP)-1. METHODS AND RESULTS MCP-1 mRNA expression was quantitated by Northern blot analysis, and its protein expression was quantitated by immunostaini...

A61-year-old woman was referred for aortocoronary bypass surgery. At cardiac catheterization, calcifications of the ascending aorta were noted. To assess the exact extent of aortic calcification, we performed an ECG-gated electronbeam CT (EBCT) study of the thoracic aorta. Our image displays a 3-dimensional volume–rendering reconstruction of the EBCT data set, with thresholds set to display cal...

The combination of coronary artery disease and its complications (ischemic mitral regurgitation etc.) with the aneurysm of the descending thoracic aorta is not a rare case. The single-stage correction of coronary/intracardiac/aortic lesions may be considered as a way of managing the combined patients. Simultaneous multi-vessel coronary artery bypass grafting, suture mitral annuloplasty and desc...

We investigated a hypothesis that an oxygen sensor involved in hypoxia-induced relaxation of vascular smooth muscle may reside in endothelial cells. We also determined the oxygen dependence of hypoxia-induced decreases in cyclic guanosine 3',5'-monophosphate concentrations in vascular smooth muscle rings. Rings of canine femoral artery, rabbit thoracic aorta, and lamb ductus arteriosus, either ...
