BACKGROUND: Vegetable growers in Arctic areas usually must rely on market strategies based on regional origin and product quality. Swede roots (rutabaga) were grown in a phytotron to investigate the effect of high latitude light conditions on sensory quality and some health and sensory-related compounds. Experimental treatments included modifications of 24 h natural day length (69° 39' N), by moving plants at daily intervals to dark chambers with either no light, fluorescent growth light and/or low intensity photoperiod extension...

Background Early detection of risk factors for left ventricular (LV) dysfunction may be useful in patients with high blood pressure (HBP). Methods Patient from an outpatient HBP clinic underwent a two-dimensional Doppler-coupled echocardiography with determination of LV global longitudinal strain (GLS) by speckle-tracking. Results Among 200 patients (mean age 61.7 ± 9.7 years), 155 were overweight, 93 had diabetes, 83 had dyslipidemia, and 109 had uncontrolled HBP. LV hypertrophy (LVH) was found in 136 patients (68%), including concentric ( n = 106) and eccentric ( n = 30) LVH...

The aim of this study was to evaluate the accuracy and feasibility of real-time 3-D echocardiography (3-DE) in assessing right ventricular (RV) systolic function. A latex balloon was inserted into the right ventricle of 20 freshly harvested pig hearts which were then passively driven by a pulsatile pump apparatus. The RV global longitudinal strain (GLS), global circumferential strain (GCS), global area strain (GAS) and RV ejection fraction (RVEF), derived from 3-DE, as well as the RVEF obtained from 2-D echocardiography (2-DE) were quantified at different stroke volumes (30-70 mL) and compared with sonomicrometry data...

BACKGROUND: 20-30% of patients do not benefit from CRT when the established selection criteria were applied. We hypothesized that a combined assessment of mechanical dyssynchrony, myocardial deformation and diastolic function would identify patients who would benefit most from CRT. METHOD: In 36 CRT patients, clinical evaluation and echocardiography were performed before and after CRT. Patients were classified into 3 subgroups according to their amount of response: echocardiographic responders, clinical responders, and nonresponders...

Patients with chronic obstructive pulmonary disease (COPD) have a high risk of mortality after acute ST-segment elevation myocardial infarction (STEMI). We compared STEMI patients with versus without COPD in terms of infarct size and left ventricular (LV) systolic function using advanced 2-dimensional speckle tracking echocardiography. Of 1,750 patients with STEMI (mean age 61 ± 12 years, 76% male), 133 (7.6%) had COPD. With transthoracic echocardiography, left ventricular ejection fraction (LVEF) and wall motion score index were measured...

Global longitudinal strain (GLS) is a sensitive indicator of global left ventricular function particularly in those with normal ejection fraction. We examined the potential value of GLS in predicting outcomes in hypertrophic cardiomyopathy (HC). Conventional and strain echocardiography was performed in 400 patients with HC followed for a median 3.1 years (interquartile range 1.2 to 5.6). Peak systolic strain from 3 apical views was averaged to calculate GLS. Patients were divided based on a previously published cutoff value of -16%...

Postprandial hypotension (PPH) occurs frequently and is thought to reflect an inadequate increase in cardiac output to compensate for the rise in splanchnic blood flow after a meal. Gastric distension by water attenuates the postprandial fall in blood pressure (BP). Cardiac hemodynamics (stroke volume (SV), cardiac output (CO), and global longitudinal strain (GLS)) have hitherto not been measured in PPH We sought to determine the comparative effects of water and glucose drinks on cardiac hemodynamics in healthy older subjects and individuals with PPH Eight healthy older subjects (age 71...

BACKGROUND: Current methods for predicting adverse events in patients with hypertrophic cardiomyopathy are still limited. Left ventricular global longitudinal strain (GLS) and left atrial volume index (LAVI) have been recently proposed as novel prognostic factors in several cardiovascular diseases. The objective of this study was to evaluate the prognostic value of GLS and LAVI in patients with hypertrophic cardiomyopathy. METHODS AND RESULTS: Two-dimensional echocardiography was performed in 427 patients with hypertrophic cardiomyopathy (66% men, age 52±15 years), and LAVI and GLS were assessed...

Background: Estimative of left ventricular ejection fraction (LVEF) is a major indication for echocardiography. Speckle tracking echocardiography (STE) allows analysis of LV contraction mechanics which includes global longitudinal strain (GLS) and twist/torsion, both the most widely used. Direct comparison of correlations between these novel parameters and LVEF has never been done before. Objective: This study aims to check which one has the highest correlation with LVEF...

Pancreatic ductal adenocarcinoma is a notoriously difficult-to-treat cancer and patients are in need of novel therapies. We have shown previously that these tumours have altered metabolic requirements, making them highly reliant on a number of adaptations including a non-canonical glutamine (Gln) metabolic pathway and that inhibition of downstream components of Gln metabolism leads to a decrease in tumour growth. Here we test whether recently developed inhibitors of glutaminase (GLS), which mediates an early step in Gln metabolism, represent a viable therapeutic strategy...

Aortic valve stenosis (AVS) is associated with significant myocardial fibrosis (MF). Global longitudinal strain (GLS) is a sensible indicator of systolic dysfunction. ST2 is a member of the interleukin (IL)-1 receptor family and a modulator of hypertrophic and fibrotic responses. We aimed at assessing: (a) the association between adverse LV remodeling, LV functional parameters (including GLS) and sST2 level. (b) The association between MF (detected by endo-myocardial biopsy) and sST2 in patients with AVS undergoing surgical valve replacement...

BACKGROUND: Newer 2D strain software has a potential to assess layer-specific strain. However, normal reference values for layer-specific strain have not been established. We aimed to establish the normal ranges of layer-specific longitudinal and circumferential strain (endocardial global longitudinal strain (GLS), transmural GLS, epicardial GLS, endocardial global circumferential strain (GCS), transmural GCS, and epicardial GCS). METHODS AND RESULTS: We retrospectively analyzed longitudinal and circumferential strain parameters in 235 healthy subjects, with use of layer-specific 2D speckle tracking software (GE)...

In the present study, we assessed the role of Global Longitudinal Strain (GLS) as a predictor of all-cause mortality in patients with severe aortic valve stenosis (AS), irrespective of their type of treatment. Data of 807 patients with AS receiving complete echocardiographic and clinical examination were retrospectively analyzed. Valve area <1 cm(2) and sufficient image quality were inclusion criteria; patients with severe concomitant valvulopathy were excluded. Patients were grouped into treatment (aortic valve replacement [AVR]) and conservative (non-AVR) groups...

Left ventricular (LV) diastolic dysfunction and longitudinal systolic dysfunction were identified in patients with diabetes mellitus (DM). This study's aim was to investigate the impact of LV longitudinal systolic function on LV diastolic function in DM patients with preserved LV ejection fraction (LVEF). We studied 177 DM patients with preserved LVEF (all ≥50%), and 82 age-, gender- and LVEF-matched healthy volunteers as control. Global longitudinal strain (GLS) was defined as the average peak strain of 18 segments from standard apical views, GLS <18% as subclinical LV systolic dysfunction (LVSD), and LV dispersion as the standard deviation of time-to-peak strain from the same views...
