Rapid occlusion of the middle cerebral artery (MCA) was undertaken in 5-6 week old rats to determine whether or not the young spontaneously hypertensive rat (SHR) or the normotensive Sprague-Dawley rat (SD) is protected against cerebral infarction by collateral circulation. Rats were killed 3 days after MCA occlusion and administration of Evans blue. As compared to SD, the SHR had elevated bloo...

A case control study was conducted to identify the systemic and ocular risk factors for retinal arterial macroaneurysms. Forty-three patients with 52 photographically confirmed macroaneurysms were located. Forty-three age-matched, race-matched concurrent control patients were also identified. The patients with macroaneurysms had decreased visual acuity (p less than 0.0001) and a higher prevalen...

Approximately one in six patients with portal hypertension who develop varices at sites of portosystemic venous collaterals has gastric varices due to hepatofugal flow into the gastric veins. Bleeding from gastric varices, though less common, has a higher mortality and morbidity compared to bleeding esophageal varices, which are easier to manage endoscopically. The efferent channel for gastric ...

Scene understanding requires reasoning about both what we can see and what is occluded. We offer a simple and general approach to infer labels of occluded background regions. Our approach incorporates estimates of visible surrounding background, detected objects, and shape priors from transferred training regions. We demonstrate the ability to infer the labels of occluded background regions in ...

A partially occluded image consists of a set of objects where some may be partially occluded by others. Validating occluded images distinguishes whether a given image can be covered by the members of a finite set of objects, where both the image and the object range over identical alphabet. The algorithm presented here validates a one-dimensional image x of length n, over a given set of objects...

background: the global health burden has faced toward non-communicable diseases (ncds). it is suggested that adulthood blood pressure (bp) is tracked from childhood. this study aims to evaluate the mean bp and the prevalence of prehypertension and hypertension in the iranian pediatric population. methods: in a national survey as the 4th phase of childhood and adolescence surveillance and preven...

The effect of transmural pressure on the responsiveness of vascular smooth muscle was studied using rats with chronic occlusion of one external iliac artery. The arterial pressure in the occluded leg was reduced to approximately half of that in the contralateral unoccluded leg. Helical strips from the low- and high-pressure femoral arteries of spontaneously hypertensive rats and rats with deoxy...

Scope of the Problem The population of children and adults who have undergone successful palliation of various forms of congenital heart disease (CHD) continues to increase and live longer. The reasons are multiple, and include expanded indications, early, more definitive surgery and other interventional techniques, and improved surgical, interventional, catheterization, electrophysiological, a...

A 67-year-old man with hypertension and without a history of claudication was admitted to our hospital with ongoing bilateral leg numbness after persistent nausea and vomiting of a few days in duration. On arrival, his legs were paralyzed with remarkable hypothermia and livedo reticularis up to the umbilicus. Contrast-enhanced computed tomography revealed an infrarenal bimodal abdominal aortic ...

We propose a learning-based framework for inferring the 3D pose of a person from monocular image sequences. We generate a silhouette from each input image via a robust background subtraction algorithm, and compute the corresponding shape context descriptor using the shape context algorithm. We compute the weighted average of neighbor poses in a database to estimate the positions of different bo...
