It is not known whether changing from isoflurane to desflurane during the latter part of anesthesia shows early emergence and recovery in long surgery. We therefore evaluated the effects of changing isoflurane to desflurane on emergence and recovery. Eighty-two patients were randomly assigned to receive isoflurane (Group I) or desflurane (Group D) or to change from isoflurane to desflurane anes...

Interaction of biomaterials with blood components including neutrophils is responsible for some of the clinical complications that have occurred in cardiopulmonary bypass, hemodialysis, and ventricular assist procedures. The possibility of inhibiting the initial adhesion of neutrophils to biomaterials has been studied extensively, but the problem remains unsolved. In this study, we investigated...

We initiated a prospective trial of an azithromycin-containing regimen for the treatment of human immunodeficiency virus-negative patients with Mycobacterium avium complex (MAC) lung disease; the initial 4 months of therapy were with azithromycin (600 mg/d) alone. The primary study endpoint was microbiological response measured at 4 and 6 months of therapy. Of 29 patients enrolled in the study,...

Two important criteria of wireless body area networks (WBANs) are low power consumption and delay. These can be met by designing efficient medium access control (MAC) protocols. In this paper, two TDMA-based MAC protocols proposed. The first protocol, TM–MAC makes use only a main radio. second proposed TWM–MAC WUR alongside the compared with different categories standard it is shown that they o...

We give a short account of the history of CT from motion tomography in the early 1930’s to sprial CT. We discuss the physical and the mathematical background. Finally we give an outlook on possible future developments of CT and related techniques. © 2002 Wiley Periodicals, Inc.

OBJECTIVES This study was conducted to evaluate mineral metabolism markers as potential risk factors for calcific aortic valve disease. BACKGROUND Mineral metabolism disturbances are common among older people and may contribute to cardiac valvular calcification. Associations of serum mineral metabolism markers with cardiac valvular calcification have not been evaluated in a well-characterized...

soil organic carbon has been the most important soil quality measurement factors and has intense relation with soil physical, chemical and biological characteristics. organic matter and its components are important factors of soil aggregates constitution and stability and play significant role in its structure.so, this research has been done for achieving this purpose. this area is arounding sa...

Wireless Sensor Networks (WSNs) comprising of tiny, power-constrained nodes are getting very popular due to their potential uses in wide applications like monitoring of environmental conditions, various military and civilian applications. The critical issue in the node is energy consumption since it is operated using battery, therefore its lifetime should be maximized for effective utilization ...
