Embryonic stem cells (ESCs) form descendants of all three germ layers when differentiated as aggregates, termed embryoid bodies. In vivo, differentiation of cells depends on signals and morphogen gradients that provide instructive and positional cues, but do such gradients exist in embryoid bodies? We report here the establishment of anteroposterior(More)
Pluripotent stem cells exist in naive and primed states, epitomized by mouse embryonic stem cells (ESCs) and the developmentally more advanced epiblast stem cells (EpiSCs; ref. 1). In the naive state of ESCs, the genome has an unusual open conformation and possesses a minimum of repressive epigenetic marks. In contrast, EpiSCs have activated the epigenetic(More)
OBJECTIVES The aim of this study was to determine the prevalence of heart failure (HF) in adult residents of Turkey based on echocardiography and N-terminal B type natriuretic factor. STUDY DESIGN 4650 randomly selected residents aged ≥ 35 years were enrolled. Height, weight, waist and hip circumference, and blood pressure measurements were taken, and a(More)
BACKGROUND There has been a continued search for a more sensitive noninvasive technique for detecting sub-clinical acute rejection in heart transplant recipients. Ultrasonic deformation imaging (strain/strain rate) is sensitive in detecting sub-clinical abnormalities in regional systolic function and could potentially be sufficiently sensitive to detect(More)
AIMS To investigate whether intracoronary transfer of bone marrow progenitor cells (BMPCs) early after reperfusion of an acute myocardial infarction improves regional myocardial function in a randomized double-blind, placebo-controlled strain rate imaging study. METHODS AND RESULTS Regional myocardial deformation was measured using velocity-derived strain(More)
Members of the SWI/SNF chromatin-remodeling complex are among the most frequently mutated genes in human cancer, but how they suppress tumorigenesis is currently unclear. Here, we use Drosophila neuroblasts to demonstrate that the SWI/SNF component Osa (ARID1) prevents tumorigenesis by ensuring correct lineage progression in stem cell lineages. We show that(More)
BACKGROUND The study evaluates the alterations in exercise capacity of chronic thromboembolic pulmonary hypertension (CTEPH) patients after pulmonary endarterectomy (PEA) and investigates the echocardiographic parameters associated with the degree of functional recovery. METHODS Thirty consecutive patients with the diagnosis of CTEPH (17 males; mean age,(More)
OBJECTIVE The aim of this study was to investigate the clinical applicability of strain and strain rate imaging (epsilon/SRI) in heart transplantation (Htx) patients and to establish "normal" post-Htx regional systolic deformation values. BACKGROUND Epsilon/SR indices have been shown to be a more sensitive measure of regional systolic function than(More)
Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in clinical practice, and there is an increasing trend in its prevalence in the general population. Recent studies have demonstrated increased risk of atrial fibrillation (AF) in NAFLD. However, information on the mechanism of increased risk of AF in NAFLD is(More)
Sibutramine is an anti-obesity drug, which acts by inhibiting neuronal re-uptake of noradrenaline and serotonin. Although the most frequently seen effect of sibutramine on cardiovascular system is an increase in blood pressure and pulse rate, rare but severe side effects such as sibutramine-induced ventricular arrhythmias, heart failure and cardiovascular(More)
