BACKGROUND Exercise-induced ST-segment elevation (STE) in lead aVR may be an important indicator of prognostically important coronary artery disease (CAD). However, the prevalence and associated clinical features of exercise-induced STE in lead aVR among consecutive patients referred for exercise stress electrocardiography (ExECG) is unknown. METHODS All consecutive patients receiving a Bruce...

Left ventricle (LV) strain measurement by using the two-dimensional (2D) speckle-tracking echocardiography (STE) was first described in 2004, 1) and has been widely applied in research , and the number of publications in the medical literature regarding the clinical utility of STE has been grown rapidly. 2)3) STE is based on frame-by-frame image tracking of tiny natural acoustic markers within ...

BACKGROUND The speckle tracking echocardiography (STE) method shows the presence of right ventricular (RV) dysfunction before the advent of RV failure and pulmonary hypertension in patients with cardiopulmonary disease. We aimed to assess subclinical RV dysfunction in obstructive sleep apnea (OSA) using the STE method. METHOD Twenty-one healthy individuals and 58 OSA patients were included. A...

The type III secretion system encoded by Salmonella pathogenicity island 2 (SPI2) translocates Salmonella translocated effectors (STE) into host cells. STE are encoded by genes outside of SPI2. The distribution of STE loci within the salmonellae was investigated. In contrast to the SPI2 locus that is conserved within Salmonella enterica, STE loci show a variable distribution. In addition to oth...

BACKGROUND Left ventricular (LV) torsion is due to oppositely directed apical and basal rotation and has been proposed as a sensitive marker of LV function. In the present study, we introduce and validate speckle tracking echocardiography (STE) as a method for assessment of LV rotation and torsion. METHODS AND RESULTS Apical and basal rotation by STE was measured from short-axis images by aut...

A non-hydrophobic sequence that contributes to the biogenesis of a transmembrane protein is termed a stop-transfer effector (STE). To examine the mechanism of STE-mediated stop-transfer, a series of fusion proteins were constructed containing variants of a putative STE from murine IgM fused to an otherwise translocated hydrophobic sequence. Unexpectedly, the fraction of molecules adopting trans...

The aim of this study was to explore the significance of different ST-segment changes before and after percutaneous coronary intervention (PCI), in relation to cardiac magnetic resonance (CMR)-verified microvascular obstruction (MVO) along with intramyocardial hemorrhage (IMH) in ST-elevation myocardial infarction (STEMI) patients.This study enrolled 108 STEMI patients who received primary PCI ...

Weighted linear prediction (WLP) is a method to compute allpole models of speech by applying temporal weighting of the residual energy. By using short-time energy (STE) as a weighting function, the algorithm over-weight those samples that fit the underlying speech production model well. The current work introduces a modified WLP method, stabilised weighted linear prediction (SWLP) leading alway...

In this paper we elucidate the mathematical foundation underlying both the basic and the extended forms of symbolic trajectory evaluation (STE), with emphasis on the latter. In addition, we make three contributions to the theory of STE which, we believe, are new. First, we provide a satisfactory answer to the question: what does it mean for a circuit to satisfy a trajectory assertion? Second, w...
