Mesenchymal stem cells could differentiate into cardiomyocytes in vitro and have been shown to reconstitute the impaired myocardium in vivo. Hepatocyte growth factor, a recognized angiogenic factor and endothelial cell chemoattractant, has been applied in the treatment of myocardial ischemia. In this study, we used a ligation model of proximal left anterior(More)
Sphingosine kinase 1 (SPK1) has been identified as a central mediator of ischemia preconditioning and plays a protective role in ischemia/reperfusion (I/R)-induced cardiomyocyte death. In the present study, we investigated the protective effect of adenovirus-mediated SPK1 gene (Ad-SPK1) transfer on I/R-induced cardiac injury, and evaluated its therapeutic(More)
BACKGROUND This study illustrates aesthetic and sensory reconstruction of finger pulp defects with free toe flaps from the lateral aspect of the great toe or the medial aspect of the second toe. METHODS Between August 2007 and July 2010, free toe flaps were harvested and used for 21 fingers of 21 patients. The average patient age was 34.5 years (range(More)
PURPOSE To investigate the feasibility of magnetically labeling stem cells with superparamagnetic iron oxide (SPIO) by means of microbubble-enhanced ultrasonographic (US) exposure (MUE) and to study the effects of this approach--without secondary transfection agents--on the viability, proliferation activity, and differentiation capability of MUE-labeled(More)
PURPOSE To assess the reproducibility of HR-MRI for the identification of MCA atherosclerotic plaque components and quantification of stenosis. MATERIALS AND METHODS Seventy-three consecutive subjects who initially had ischemic stroke or asymptomatic MCA stenosis (>50%) were enrolled in the study. All subjects were scanned using 3.0T MRI. Two independent(More)
Hepatocyte growth factor (HGF) is one of major growth factors in the bone marrow microenvironments with which the proliferation, differentiation and migration of bone marrow-derived mesenchymal stem cells were closely contacted. However, its roles in the regulation of proliferation, differentiation and migration of bone marrow-derived mesenchymal stem cells(More)
BACKGROUND Previous studies have focused on the association of miR-34 family members with carcinogenesis of many cancers, including hepatocellular carcinoma (HCC). It has been suggested that miR-34b/c polymorphism (rs4938723) is associated with susceptibility to HCC. In the present study, we performed a meta-analysis to systematically summarize the possible(More)
Distal esophageal adenocarcinoma is a highly aggressive neoplasm. Despite advances in diagnosis and therapy, the prognosis is still poor. Stathmin (STMN-1) is a ubiquitously expressed microtubule destabilizing phosphoprotein. It promotes the disassembly of microtubules and prevents assembly. STMN-1 can cause uncontrolled cell proliferation when mutated and(More)
INTRODUCTION We aimed to determine a potentially optimal body size index for adjusting the tube current in retrospective ECG-triggered helical 256-slice CT coronary angiography (CTCA) for individualized radiation dose control. METHODS Consecutive patients (n=102) with suspected coronary artery disease underwent retrospective ECG-triggered CTCA with a(More)
AIM The roles of AMP-activated protein kinase (AMPK) and myocyte enhancer factor 2 isoforms (MEF2A, D) as mediators of the effects of ethanol on glucose transporter 4 (GLUT4) expression are unclear. We studied the effects of ethanol in adipocytes in vivo and in vitro. METHODS Thirty-six male Wistar rats were divided into three groups and given ethanol in(More)
