AIMS In aortic stenosis (AS), both reduced systemic arterial compliance and increased valvular load have been shown to contribute to impaired left ventricular (LV) function. However, the relationship between LV function and aortic stiffness has not yet been investigated. We aimed to assess the relationship between aortic stiffness and LV global longitudinal strain (GLS), LV filling pressures (E...

Assessment of global longitudinal systolic strain (GLS) and longitudinal systolic strain of the basal segments (BLS) has shown prognostic value in cardiac disorders. However, strain is reduced with increased afterload. We assessed the prognostic value of GLS and BLS adjusted for afterload. GLS and BLS were determined in 272 subjects with normal ejection fraction and no known coronary disease, o...

Myocardium subtended by obstructive coronary artery disease (CAD) may show reduced left ventricle (LV) global longitudinal strain (GLS), as well as early systolic lengthening (ESL) before shortening; these can be measured at rest and may predict obstructive CAD. This study investigated whether baseline resting LV longitudinal strain measurements may be able to detect significant CAD in patients...

The guided local search method has been successfully applied to a significant number of NP-hard optimization problems, producing results of similar caliber, if not better, compared to those obtained from algorithms specially designed for each singular optimization problem. Ranging from the familiar TSP and QAP to general function optimization problems, GLS sits atop many well-known algorithms s...

We introduce the method of geodesic least squares (GLS) regression for estimating fusion scaling laws. Based on straightforward principles, the method is easily implemented, yet it clearly outperforms established regression techniques, particularly in cases of significant uncertainty on both the response and predictor variables. We apply GLS for estimating the scaling of the L-H power threshold...

CRP 3.5 is a comprehensive proposal built around combined research on eight grain legumes (GLs) – groundnut, soybean, chickpea, cowpea, common bean, pigeon pea, lentil, and faba bean – proposed by four CGIAR Centres (ICARDA, ICRISAT, IITA and CIAT) and by several NARES (India, Brazil, Turkey and Ethiopia). These crops are important dietary staples and sources of income for farmers in many, low ...

INTRODUCTION The aim of this study was to examine the association of night-time systolic blood pressure (BP) with subclinical cardiac dysfunction measured by global longitudinal strain (GLS) and subclinical vascular damage measured by carotid intima-media thickness (CIMT) and carotid plaques. METHODS GLS was measured by speckle-tracking analysis of echocardiogram images. CIMT was measured at ...

BACKGROUND The renal vasculature plays important roles in both homeostasis and pathology. In this study, we examined pathological changes in the renal microvascular in mouse models of kidney diseases. METHODS Glomerular lesions (GLs) in autoimmune disease-prone male BXSB/MpJ-Yaa (Yaa) mice and tubulointerstitial lesions (TILs) in male C57BL/6 mice subjected to unilateral ureteral obstruction ...

Many angiosperm plants, including basal dicots, eudicots, and monocots, emit (E,E)-4,8,12-trimethyltrideca-1,3,7,11-tetraene, which is derived from geranyllinalool, in response to biotic challenge. An Arabidopsis (Arabidopsis thaliana) geranyllinalool synthase (GLS) belonging to the e/f clade of the terpene synthase (TPS) family and two Fabaceae GLSs that belong to the TPS-g clade have been rep...

BACKGROUND Current guidelines recommend intervention for symptomatic aortic stenosis, but the management of asymptomatic aortic stenosis remains controversial. As left ventricular global longitudinal strain (GLS) has been shown to predict cardiovascular outcome, we sought to find whether its use could guide the assessment of risk in these patients. METHODS AND RESULTS We prospectively followe...
