Transthoracic Doppler echocardiography is emerging as a promising method for evaluating coronary artery disease. After a period of training, detection and measurement of distal left anterior descending coronary artery flow with transthoracic Doppler echocardiography is feasible in more than 90% of the patients. Using transthoracic Doppler echocardiography(More)
BACKGROUND Helicobacter pylori has generally been observed only in the gastric mucous layer or in the spaces between gastric mucus-secreting cells and not in the gastric epithelial cells or in the lamina propria. The purpose of this study is to determine whether H. pylori invades the gastric mucosa, using an immunoelectron microscopical examination of human(More)
BACKGROUND The aim of the present study was to analyze the parameters related to baseline coronary flow velocity (CFV) and coronary flow reserve (CFR) using Doppler transthoracic echocardiography (TTE), and to assess their associations with components of the Framingham risk score (FRS), which estimates 10-year risk of coronary heart disease, in subjects(More)
PURPOSE The cold pressor test (CPT) has been used to detect variant angina, but its sensitivity in predicting vasospasm is low. The aim of this study was to determine whether estimates of the coronary flow velocity reserve (CFVR) in the distal left anterior descending coronary artery (dLAD) using transthoracic echocardiography (TTE) and CPT are useful tool(More)
BACKGROUND AND OBJECTIVES Although there have been so many reports of catheter ablation of atrial fibrillation (AF) with magnetic navigation system (MNS), it is not necessarily obvious that MNS is more effective than conventional ablation. We performed AF ablation with MNS and compared the clinical outcomes and radiofrequency ablation parameters with those(More)
The gene structure and expression of the linear mitochondrial plasmids of the white-rot fungus Pleurotus ostreatus, pMLP1 and pMLP2, were analyzed. Cleavage by proteinase K and exonucleases indicated that the 5' ends of pMLP1 and pMLP2 DNAs were associated with terminal proteins. Nucleotide sequencing of the entire pMLP1 DNA revealed that it consists of(More)
OBJECTIVE We evaluated prevalence and severity of angiographic coronary artery disease (CAD) according to groups by metabolically obese (MO) and/or weight status. MATERIAL/METHODS Normal weight was defined as body mass index (BMI, kg/m²)<25 and obesity was defined as BMI≥25. The MO was determined using the National Cholesterol Education Program-Adult(More)
BACKGROUND There is little data about the additive effects of ischemia-modified albumin (IMA) on the exercise stress test (EST) used for the screening of ischemic heart disease. The relationship between myocardial ischemic burden and the change in IMA (DeltaIMA) during EST was investigated. METHODS AND RESULTS EST was performed using the Bruce protocol to(More)
Helicobacter pylori causes type B gastritis. It shows strong association with the development of gastric carcinoma. A plausible hypothesis for the missing link between H. pylori infection and gastric carcinogenesis involves oxygen free radical-induced DNA damage. To test this hypothesis, we compared the amount of 9-hydroxydeoxyguanosine, a marker for oxygen(More)
BACKGROUND Coronary flow reserve (CFR) capacity of penetrating intramyocardial coronary artery (PICA) in apical hypertrophic (AH) cardiomyopathy has not been studied yet. METHODS We studied 65 patients with normal coronary angiogram results (mean age 56 +/- 10 years; 33 men, 32 women). Of these, 30 were normotensive without any left ventricular(More)
