The purpose of this study was to determine whether exposure of cultured chemically transformed hamster oral keratinocytes (HCPC-1) to an aqueous extract of smokeless tobacco (STE) potentiates DNA synthesis elicited by vasoactive intestinal peptide (VIP), an autocrine neuropeptide, and, if so, whether this response is associated with inactivation of neutral endopeptidase 24.11 (NEP 24. 11), an e...

Cardiac function analysis is the main focus of echocardiography. Left ventricular ejection fraction (LVEF) has been the clinical standard, however, LVEF is not enough to investigate myocardial function. For the last decade, speckle tracking echocardiography (STE) has been the novel clinical tool for regional and global myocardial function analysis. However, 2-dimensional imaging methods have li...

The stem terminus element (STE), which was discovered 13 y ago in human telomerase RNA, is required for telomerase activity, yet its mode of action is unknown. We report that the Schizosaccharomyces pombe telomerase RNA, TER1 (telomerase RNA 1), also contains a STE, which is essential for telomere maintenance. Cells expressing a partial loss-of-function TER1 STE allele maintained short stable t...

We present a new SAT-based algorithm for Symbolic Trajectory Evaluation (STE), and compare it to more established SAT-based techniques for STE.

In this paper, we present an algorithm for Voice Activity Detection (VAD) in speech signals using the minimum phase group delay function. The proposed method considers a buffer consisting of contiguous frames of the given signal and computes the short-term energy (STE) for that buffer. By appending a surrogate signal to STE and viewing the resultant signal as a positive part of the magnitude sp...

The secondary transfer effect (STE) constitutes the generalization of effects intergroup contact from outgroup one has with to uninvolved outgroups. In this article, we provide a review research on STE. After presenting evidence robustness phenomenon, discuss relevant mediating processes and outline model that distinguishes them in three categories: mediators referring outgroup, ingroup, self. ...

OBJECTIVE Saturated fats increase total cholesterol (TC) and low density lipoprotein-cholesterol (LDL-C) and are linked to coronary artery disease risk. The effect of variance in chain length of saturated fatty acids (SFA) on coronary artery disease in human postprandial lipemia is not well elucidated. METHODS A total of 20 healthy volunteers were challenged with 3 test meals, similar in fat ...

BACKGROUND Spatial orientation of left ventricular (LV) apical segments is a potential limitation to assessment by tissue Doppler echocardiography (TDE). Speckle tracking echocardiography (STE) is a recently developed quantification technique and has the advantage of being angle-independent as compared to TDE. AIM To assess matching apical segments' longitudinal strain data from TDE and STE. ...

Symbolic Trajectory Evaluation (STE) is a powerful technique for hardware model checking. It is based on 3-valued symbolic simulation, using 0,1, and X (“unknown”). X is used to abstract away values of circuit nodes, thus reducing memory and runtime of STE runs. The abstraction is derived from a given user specification. An STE run results in “pass” (1), if the circuit satisfies the specificati...

BackgroundThe standard 12-lead electrocardiogram (ECG) has relatively low sensitivity for the diagnosis of posterior wall acute myocardial infarction (AMI). The prevalence of posterior wall myocardial infarction (MI) has been studied in a few studies. We evaluated ST-segment elevation (STE) prevalence in posterior leads in patients with acute coronary syndrome (ACS) in order to determine the pr...
