BACKGROUND We used cardiovascular magnetic resonance (CMR) to investigate the association between epicardial adipose tissue (EAT) thickness and silent myocardial ischemia, as well as coronary artery stenosis, in asymptomatic type 2 diabetic patients. METHODS The study included 100 type 2 diabetic subjects (51 male and 49 female; mean age: 56 ± 7 years).(More)
PURPOSE To evaluate the clinical feasibility and accuracy of 64-section multidetector computed tomography (CT) compared with transesophageal echocardiography (TEE) for diagnosis of a patent foramen ovale (PFO). MATERIALS AND METHODS Institutional review board approval was obtained for this retrospective study. The study included 152 consecutive stroke(More)
NDR (nuclear Dbf2-related) kinases are essential components for polarized morphogenesis, cytokinesis, cell proliferation, and apoptosis. The NDR kinase Cbk1 is required for the hyphal growth of Candida albicans; however, the molecular functions of Cbk1 in hyphal morphogenesis are largely unknown. Here, we report that Cbk1 downregulates the transcriptional(More)
AMP-activated protein kinase (AMPK) functions as an energy sensor to provide metabolic adaptations under the ATP-deprived conditions such as hypoxia. In the present study, we considered a role of AMPK in the adaptive response to hypoxia by examining whether AMPK is involved in the regulation of hypoxia-inducible factor-1 (HIF-1), a heterodimeric(More)
BACKGROUND Endoscopic stone removal is difficult in patients with a Billroth II gastrectomy. OBJECTIVE To evaluate the usefulness of a rotatable papillotome and large-balloon dilation for removing bile-duct stones in patients with a Billroth II gastrectomy. DESIGN A case series. SETTING A large tertiary-referral center. PATIENTS AND INTERVENTION(More)
PURPOSE To assess the diagnostic accuracy of two-phase 64-section cardiac computed tomographic (CT) angiography for detection of left atrial appendage (LAA) thrombi and differentiation between thrombus and circulatory stasis in patients with stroke, with transesophageal echocardiography (TEE) as the reference standard. MATERIALS AND METHODS This study was(More)
BACKGROUND AND PURPOSE A noninvasive method with high reliability and accuracy comparable to transesophageal echocardiography for identification of left atrial appendage thrombus would be of significant clinical value. The aim of this study was to assess the diagnostic performance of a dual-enhanced cardiac CT protocol for detection of left atrial appendage(More)
OBJECTIVE We sought to systemically analyze the characteristics of fat accumulation in patients with myocardial infarction (MI) relative to various clinical parameters. MATERIALS AND METHODS We included 161 patients (129 men, 32 women; mean age, 60.7 years) who had previously been diagnosed with MI and had undergone CT coronary angiography between(More)
We evaluated radiation doses, complication rates, and diagnostic accuracy for CT-guided percutaneous needle aspiration biopsy (NAB) procedures of pulmonary lesions performed with or without fluoroscopic guidance. A total of 142 patients were prospectively enrolled to receive CT-guided NAB with (Group I, n = 72) or without (Group II, n = 70) fluoroscopic(More)
PURPOSE To evaluate inter- and intra-observer variabilities in breast sonographic feature analysis and management, using the fourth edition of the Breast Imaging Reporting and Data System (BI-RADS). MATERIALS AND METHODS We included 136 patients with 150 breast lesions who underwent breast ultrasound (US) and ultrasound-guided core needle biopsy. A(More)
