INTRODUCTION Serial echocardiographic assessment of left ventricular ejection fraction (LVEF) is the gold standard in screening for chemotherapy-induced cardiotoxicity (CIC). Measurement of myocardial deformation using speckle tracking enables more detailed assessment of myocardial contractility. The aim of this study was to determine the relationship between global and regional longitudinal st...

OBJECTIVE There are many factors related to high left atrial volume index (LAVI) and global left ventricular longitudinal peak systolic strain (GLS-%) decline in chronic kidney disease. The purpose of our study is to investigate the relation between the ß-2 microglobulin (ß-2µ ) and GLS-% and LAVI in patients with chronic kidney disease not yet on dialysis. METHODS Our study was a non-randomi...

Gray leaf spot (GLS), caused by Cercospora zeae-maydis and Cercospora zeina, is one of the most important diseases of maize worldwide. The pathogen has a necrotrophic lifestyle and no major genes are known for GLS. Quantitative resistance, although poorly understood, is important for GLS management. We used genetic mapping to refine understanding of the genetic architecture of GLS resistance an...

AIMS There are very few data regarding the assessment and prognostic value of left ventricular contractile reserve (LVCR) in asymptomatic patients with primary mitral regurgitation (MR). We aimed to quantify LVCR and to evaluate its usefulness for risk stratification in asymptomatic patients with primary MR. METHODS AND RESULTS Comprehensive resting and exercise (EX) transthoracic echocardiog...

Gallium lanthanum sulfide glass (GLS) has been widely studied in the last 40 years for middle-infrared applications. In this work, the results of the substitution of selenium for sulphur in GLS glass are described. The samples are prepared via melt-quench method in an argon-purged atmosphere. A wide range of compositional substitutions are studied to define the glass-forming region of the modif...

Guided Local Search (GLS) has been shown to be successful in solving a number of practical real life problems, such as the travelling salesman problem, radio link frequency assignment problem and the vehicle routing problem. GLS is a penalty-based metaheuristic, which works by augmenting the objective function of a local search algorithm with penalties, to help guide them out of local minima. O...

In 2009, a lossless compression algorithm based on 1D chaotic maps known as Generalized Luröth Series (or GLS) has been proposed. This algorithm (GLS-coding) encodes the input message as a symbolic sequence on an appropriate 1D chaotic map (GLS) and the compressed file is obtained as the initial value by iterating backwards on the map. For ergodic sources, it was shown that GLS-coding achieves ...

The minimally invasive laparoscopic approach in the surgical treatment of diseases during pregnancy has become progressively more accepted and applied. In an attempt to overcome the potential adverse effects of pneumoperitoneum on the fetus, gasless laparoscopic surgery (GLS) has been developed. This article reviews the evidence available for the role and effectiveness of GLS in pregnancy. A co...

Altered glucose metabolism in cancer cells is termed the Warburg effect, which describes the propensity of most cancer cells to take up glucose avidly and convert it primarily to lactate, despite available oxygen. Notwithstanding the renewed interest in the Warburg effect, cancer cells also depend on continued mitochondrial function for metabolism, specifically glutaminolysis that catabolizes g...
