we assessed different systolic cardiac indices to detect left and right ventricular systolic dysfunction in cirrhotic patients before liver transplantation. between 2010-2011, 81 consecutive individuals with confirmed hepatic cirrhosis who were a candidate for liver transplantation were enrolled in this study. a total of 32 age and sex matched healthy volunteers were also selected as the contro...

To the Editor: Elevated blood pressure (BP) is positively correlated with age, stroke, coronary heart disease, end-stage renal disease, and heart failure. Hypertension is, usually, diagnosed by the measurement of systolic or diastolic BP. Achievement of normalization of BP is often considered the goal of hypertension management. Therefore, a valid, accurate, and reliable method is essential for...

conclusions with a thorough preoperative assessment incorporating focused echocardiography, anaesthetists are in the unique position to enhance their role as perioperative physicians and influence short and long term outcomes of their patients. context patients with undifferentiated systolic murmurs present commonly during the perioperative period. traditional bedside assessment and auscultatio...

Myocardial bridging (MB) is a congenital anomaly characterized by systolic compression of the tunnelled arterial segment. MB may cause myocardial ischaemia due to abnormal coronary blood flow. We report a case of MB in which transthoracic Doppler echocardiography was used to evaluate the long-term effect of beta-blocker therapy on abnormal coronary blood flow. In this case, beta-blocker therapy...

Peripheral MR Angiography is rapidly developing and becoming the standard method for evaluating peripheral vascular disease. MRA allows accurate and detailed assessment of peripheral vasculature without requiring arterial catheterization, nephrotoxic contrast, or ionizing radiation. Latest improvements in this area include time-resolved MR angiography, stepping table bolus chase 3D MR angiograp...

We present a parallel algorithm, architecture, and implementation for eecient Lempel-Ziv-based data compression. The parallel algorithm exhibits a scalable, pa-rameterized, and regular structure and is well suited for VLSI array implementation. Based on our parallel algorithm and systematic design methodologies 12], two semi-systolic array architectures have been developed which are low power a...

geometric and material nonlinear behavior of slender webs in i-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. interaction curves corresponding to the application of compressive and shear loads at buckling and ultimate stages for both web plates and column sections are plotted. in addition, the effects of flange and web slenderness rati...

The effect of external calf compression on baroreflex sensitivity (BRS) during electrically evoked plantar flexion and postexercise circulatory occlusion (PECO) was studied. Subjects took part in two experimental trials: control and compression. In both trials, electrically evoked isometric plantarflexion (Stim) was performed at 30% maximum voluntary contraction force for 2 min. During compress...

We present a new compact, power-efficient, and scalable VLSI array for the first Lempel-Ziv algorithm to be used in high-speed wireless data communication systems. This is part of a project at the University of Massachusetts to develop reliable and secure high-speed wireless LANs by exploiting novel VLSI technology, communications algorithms and network protocols. For wireless LANs to be seamle...
