We describe two cases with Behcet's disease (BD) developing osteonecrosis or bone infarction. One patient developed the extensive bone infarction of the left knee without the use of corticosteroids. The other patient had osteonecrosis at the right femoral head. He had had a past history of significant corticosteroid administration to treat several(More)
Nucleic acid amplification techniques are used frequently for rapid diagnosis of viral diseases. In this study, a real-time polymerase chain reaction protocol that uses primers specific for the viral VP4 gene and the commercial SYBR Green reagent were evaluated for the quantitative measurement of human rotavirus (HRV) RNA in human stool specimens. SYBR(More)
Epidemiologic and clinical data suggest that Helicobacter pylori infection is a contributing factor in the progression of atherosclerosis. However, the specific cardiovascular disease risk factors associated with H. pylori remain unclear. We performed a cross-sectional study of 37,263 consecutive healthy subjects who underwent a routine health check-up. In(More)
Insect cell culture has greatly increased in part due to the widespread use of insect virus-based vectors for efficient expression of foreign proteins. Insect cells such as Sf9 cells are susceptible to arboviruses which may pose a safety concern by adventitious introduction during the production process. The objective of this study was to establish(More)
The presence of hepatitis B virus x (HBx) antigen/antibody is known to correlate with the well-established serological markers of ongoing viral replication in the chronic phase of HBV infection, and strongly suggests that the level and duration of HBx expression may influence the outcome of the chronic infection. In this research, we developed a polymerase(More)
Previous studies have suggested a link between Helicobacter pylori (H. pylori) infection and nonalcoholic fatty liver disease (NAFLD), yet large-scale longitudinal studies are lacking to elucidate this association. A cohort study of 17,028 adults without NAFLD at baseline, who participated in a repeated health screening examination including an H.(More)
OBJECTIVE To assess the value of applying MultiVane to liver T2-weighted imaging (T2WI) compared with conventional T2WIs with emphasis on detection of focal liver lesions. MATERIALS AND METHODS Seventy-eight patients (43 men and 35 women) with 86 hepatic lesions and 20 pancreatico-biliary diseases underwent MRI including T2WIs acquired using breath-hold(More)
PURPOSE The purpose of this study was to analyze the relationship between age at menarche and myopia in Korean adult females. METHODS A total of 8398 women of at least 19 years of age, who participated in the Korean National Health and Nutrition Examination Survey from 2008 to 2012, underwent a refractive examination using an autorefractor. The(More)
BACKGROUND The role of Helicobacter pylori (H. pylori) in the development of colorectal neoplasm remains controversial. We examined the association between H. pylori infection and colorectal neoplasm in a large sample of healthy participants who underwent screening colonoscopy. METHODS A cross-sectional study of 8916 men, who participated in a regular(More)
BACKGROUND AND AIMS In individuals with either no or 1 to 2 nonadvanced adenomas, future risks of advanced colorectal neoplasia (AN) vary according to the clinical risk factors. However, little is known about the association between the adenoma detection rate (ADR) and the risk for metachronous AN in patients with low-risk adenomas. METHODS We identified(More)
