The HER-2/neu protein is intimately involved with normal cell proliferation and tissue growth and is extensively homologous and related to the epidermal growth factor receptor. HER-2/neu protein expression has been most intensively studied in the context of breast carcinoma, in which its amplification and overexpression correlate with the overall course of(More)
BACKGROUND AND AIM Differences in the prevalence of non-alcoholic fatty liver disease (NAFLD) between Eastern and Western populations are primarily attributable to differences in definitions and biased population selection. Thus, the aim of the present study was to accurately determine the actual prevalence of NAFLD by sonography and to characterize the(More)
BACKGROUND AND AIM Although insulin resistance is often considered the link between obesity and non-alcoholic fatty liver disease (NAFLD), the role of insulin resistance, independent of obesity, as a NAFLD risk factor in non-obese men has been less well established. Systemic inflammation may be accompanied by insulin resistance in healthy subjects. The goal(More)
BACKGROUND There has been no report concerning the factors that contribute to the technical difficulty of endoscopic clearance of common bile duct (CBD) stones. OBJECTIVE Our purpose was to determine the factors that contribute to the technical difficulty of endoscopic clearance of CBD stones. DESIGN Prospective study. SETTING A tertiary referral(More)
The HER-2/neu protein is intimately involved with normal cell proliferation and tissue growth, as it is extensively homologous and is related to the epidermal growth factor receptor. This phenomenon has been most intensively studied in the context of breast carcinoma, in which its amplification and overexpression correlate with the overall course of disease(More)
BACKGROUND/AIMS This study evaluated the relationship between hyperuricemia and nonalcoholic fatty liver disease (NAFLD) by comparing the incidence rates of NAFLD in relation to serum uric acid levels in apparently healthy subjects during a 5-year period. METHODS Among 15,638 healthy Korean subjects who participated in a health-screening program in 2003(More)
We evaluated a new immunoblot assay (Helicoblot 2.1) for Helicobacter pylori infection and CagA and VacA status by using serum samples from 222 patients. The test accurately detected H. pylori infection and VacA status, but improvements in the interpretation criteria are required before it can be recommended for determination of CagA status.

Reports concerning the clinical usefulness of 18F 2-fluoro-2-deoxy-d-glucose integrated positron emission and computed tomography (18F-FDG PET-CT) for patients with gallbladder cancer and cholangiocarcinoma are relatively scarce. The purpose of this study was to assess the diagnostic value of PET-CT in relation to a conventional imaging modality,(More)
Nonalcoholic fatty liver disease (NAFLD) has been associated with metabolic disorders, including central obesity, dyslipidema, hypertension, and hyperglycemia. Metabolic syndrome, obesity, and insulin resistance are major risk factors in the pathogenesis of NAFLD. The aim of this study was to identify the relative contribution of the metabolic syndrome,(More)
