BACKGROUND Two-dimensional speckle tracking provides valuable information for regional wall motion abnormalities. The purpose of this study was to determine the diagnostic value of left ventricular longitudinal strain and torsion to diagnose coronary artery disease during dobutamine stress echocardiography. METHODS We studied 100 patients (mean age 60.8 ± 10.7 years, 72 male) with known or su...

background: heat stress is one of the agents in the work environment that can create numerous problems for workers. the objective of this research is to study heat stress control in the foundry platform of a steel plant in tehran. methods: in this experimental study, controlling plans were demonstrated for the work conditions improvement in one of steel plant's foundry platforms. for controllin...

BACKGROUND Wall motion score at dobutamine stress echocardiography is an independent predictor of mortality. We sought to determine whether quantification of DSE by strain rate imaging was incremental to wall motion score for predicting outcome. METHODS AND RESULTS In 646 patients undergoing dobutamine stress echocardiography for the evaluation of known or suspected coronary disease, customiz...

Objective: To determine the effectivness of muscle energy technique versus strain counter techniques on trigger points quadratus lumborum among patients with low back pain. Methodology: A quasi-experimental trial was conducted 40 who had pain due to in Sialkot medical complex hospital, Sialkot. The participants were divided into group (MET) and B (SCS). Group treated moist heat therapy, while t...

Measures of several intrauterine position variables as well as an index of abnormality of fetal commissure development (z score) were obtained for fetuses of two substrains of BALB mice, BALB/cWah1 and BALB/cWah2, known to differ as adults in the proportion of animals exhibiting deficient corpus callosum (about 55% & 20% respectively). The extent of midline commissure development at embryonic D...

A hyperthermophilic methanogen, strain JH146(T), was isolated from 26 °C hydrothermal vent fluid emanating from a crack in basaltic rock at Marker 113 vent, Axial Seamount in the northeastern Pacific Ocean. It was identified as an obligate anaerobe that uses only H2 and CO2 for growth. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain is more than 97% similar to othe...
