conclusions it seems that there is no difference in the use of heparinized and normal saline solutions to prevent catheter occlusion of arterial and central venous pressure. patients and methods in the current randomized controlled trial, 100 patients, with an age range of 18 - 65 years of valve and coronary artery surgery were studied in rajaie heart center, tehran, iran. patients were randomi...

Introduction. Increased resistance of the heart to ischemia/reperfusion (I/R) is an urgent aim physiology, pharmacology, and cardiac surgery, since I/R injury often cause cardiogenic shock subsequent death patients in postoperative period. Materials methods. The study was carried out male rats which were subjected coronary artery occlusion (45 min) reperfusion (2 h). Before occlusion, early hyp...

The influence of common carotid occlusion on intraocular pressure was studied in rabbits by perfusion and tonographic techniques. Bilateral common carotid occlusion caused a greater ocular volume change than homolateral occlusion. If homolateral occlusion was followed by contralateral occlusion, there was consistently an additional fall in intraocular pressure. The initial fall in intraocular p...

A method for solving the stereo matching problem in the presence of large occlusion is presented. A data structure | the disparity space image | is de ned to facilitate the description of the e ects of occlusion on the stereo matching process and in particular on dynammic programming (DP) solutions that nd matches and occlusions simultaneously. We signi cantly improve upon existing DP stereo ma...

Occlusion detection is a fundamental and important problem in optical sensor inspection planning. Many viewplanning algorithms have been developed for optical inspection, however, few of them explicitly develop practical algorithms for occlusion detection. This paper presents a hierarchical space partition approach that divides both positional and surface normal space of an object for fast occl...

Robust real-time face tracking is a challenging task. This paper presents an algorithm for tracking faces of multiple people even in case of total occlusion. The method uses the color distribution of each face with the mean shift tracking method. Mean shift tracking is fast and robust to partial occlusion, and it is rotation invariant and computationally efficient. Since the mean shift algorith...

Neutral red staining was evaluated as an acute outcome assessment method in rat models of cerebral ischemia by comparison with histological infarction volume. Fischer 344 rats (n = 48) were used in three different models of middle cerebral artery (MCA) occlusion: proximal MCA occlusion (n = 16), distal MCA occlusion followed by ipsilateral common carotid artery (CCA) occlusion (distal MCA/CCA o...

In this study the occlusion effect was quantified for five types of earmolds with different venting. Nine normal-hearing listeners and ten experienced hearing aid users were provided with conventional earmolds with 1.6 and 2.4 mm circular venting, shell type earmolds with a novel vent design with equivalent cross-sectional vent areas, and nonoccluding soft silicone eartips of a commercial heari...

Abstract Background and Aims Previous studies in chronic kidney disease (CKD) showed that vascular dysfunction different circulatory beds is progressively deteriorating with CKD severity. This study evaluated muscle oxygenation microvascular reactivity at rest, during an occlusion-reperfusion maneuver, exercise patients pre-dialysis versus controls, as well between stages Method Continuous meas...

A method for incorporating intensity edge information into the recovery of occlusion regions using a pixel-based stereo algorithm is presented. We review the construction of disparity-space images and their use to solve the stereo occlusion problem. We show the impact of intensity edges on the disparity space images, and extend our stereo technique to use information about intensity discontinui...
