BACKGROUND Osteopontin (OPN) and carbonic anhydrase IX (CAIX), which are expressed on the surface of tumor cells, are associated with hypoxia during tumor development and progression. However, the roles of these proteins in the plasma of patients with non-small cell lung cancer (NSCLC) are poorly understood. Herein, we hypothesized that plasma OPN and CAIX(More)
Primary aortoenteric fistula (PAEF) is a rare but catastrophic cause of massive gastrointestinal bleeding. Diagnosis of PAEF is difficult to make and is frequently delayed without strong clinical suspicion. Timely surgical intervention is essential for patient's survival. We report on a case of an 86-year-old woman with no history of abdominal surgery, who(More)
A double-stranded RNA plasmid which confers the superkiller phenotype was transferred into a wine yeast (Montrachet strain 522) and its leucine-requiring derivative (strain 694) by cytoduction, using the protoplast fusion technique. The killer wine yeast constructed completely suppressed the growth of killer-sensitive strains of Saccharomyces cerevisiae in(More)
BACKGROUND The treatment of unprotected left main coronary artery (uLMCA) bifurcation lesions remains challenging. HYPOTHESIS We hypothesized that the type of drug-eluting stent would correlate with clinical outcomes for the treatment of uLMCA bifurcation lesions. METHODS One hundred fifteen patients who underwent stent implantation using a provisional(More)
AIM To investigate whether nonalcoholic fatty liver disease (NAFLD) affects coronary artery disease (CAD) and identify candidate mediators. METHODS Patients who underwent coronary angiography were consecutively recruited. The patients were classified into four groups by coronary artery stenosis: A, insignificant; B, one-vessel disease; C, two-vessel(More)
OBJECTIVES The aims of this study were to: 1) compare early diastolic mitral annular velocity (E') of septal annulus (SE') with E' of lateral mitral annulus (LE') and right lateral tricuspid annulus (RE') in patients with constrictive pericarditis (CP) and restrictive cardiomyopathy (RCM); and 2) assess the relationship between pericardial thickness(More)
INTRODUCTION The development of reliable gene expression profiling technology increasingly impacts our understanding of lung cancer biology. Here, we used RNA sequencing (RNA-Seq) to compare the transcriptomes of non-small cell lung cancer (NSCLC) and normal lung tissues and to investigate expression in lung cancer tissues. METHODS We enrolled 88 male(More)
PURPOSE In some patients with an implantable cardioverter defibrillator (ICD), multiple episodes of electrical storm (ES) can occur. We assessed the prevalence, features, and predictors of ES in patients with ICD. MATERIALS AND METHODS Eighty-five patients with an ICD were analyzed. ES was defined as the occurrence of two or more ventricular(More)
BACKGROUND Miyoshi myopathy (MM) is an autosomal recessive distal myopathy characterized by early adult onset. Cardiomyopathy is a major clinical manifestation in other muscular dystrophies and an important prognostic factor. Although dysferlin is highly expressed in cardiac muscle, the effect of dysferlin deficiency in cardiac muscle has not been studied.(More)
BACKGROUND AIMS Critical pathways (CP) are clinical management plans that provide the sequence and timing of actions of medical staff. The main goal of a CP is to provide optimal patient care and to improve time-effectiveness. Current guidelines for the treatment of ST-segment elevation myocardial infarction (STEMI) recommend a door-to-balloon time of <90(More)
