BACKGROUND AND PURPOSE The aim of the study was to selectively examine the effects of converting enzyme inhibition on the large brain arteries by using concomitant inhibition of carbonic anhydrase to cause severe dilatation of mainly parenchymal resistance vessels. METHODS Cerebral blood flow was measured using the xenon-133 injection technique in three groups of Wistar rats either during car...

Images are considered as one of the most important medium of conveying information, in the field of computer vision, by understanding images the information extracted from them can be used for other tasks. Image mosaic is the process of partitioning a digital image into multiple segments. Image de noising is done before the mosaic to avoid the selection of falsely object for mosaic to segment t...

The reaction of the renin-angiotensin system to acute angiotensin converting enzyme inhibition was investigated in a single-blind, crossover study in nine normal volunteers receiving two out of three regimens in random order: the new converting enzyme inhibitor benazepril (20 mg once or 5 mg four times at 6-hour intervals) or enalapril (20 mg). Plasma converting enzyme activity, drug levels, an...

Quotienting by simulation equivalences is awell-established technique for reducing the size of nondeterministic Büchi automata.We adapt this technique to alternating Büchi automata. To this end we suggest two new quotients, namely minimax and semi-elective quotients, prove that they preserve the recognized languages, and show that computing them is not more difficult than computing quotients fo...

BACKGROUND Increased serum levels of angiotensin converting enzyme and lysozyme are considered as inflammatory markers for diagnosis of sarcoidosis which is an autoimmune inflammatory disease. The purpose of this study is to evaluate the significance of differences in serum angiotensin converting enzyme and lysozyme levels of patients with ocular involvement of other autoimmune inflammatory and...

This study designed a multi-functional reconfigurable transmitarray with switchable polarization and beam steering capabilities using only PIN diode having ON/OFF switching ability. The simulation confirmed that the proposed architecture is capable of 2D scanning up to ±45° for elevation azimuth while maintaining or converting linear when operating within X-band. performance was verified throug...

abstract: today, informal settlements have been accepted in the cities and towns as a problem and an urban fact facing urban and regional management in different countries of the world. according to past experiences and the evolutions of today, searching for new and efficient solutions in order to improve the quality of these settlements in line with converting them into a habitable zone of urb...
