BACKGROUND The studies concerning the association between Helicobacter pylori status and colorectal adenoma, premalignant lesions of colorectal cancers, are not consistent. METHODS This cross-sectional study investigated the association of colorectal adenoma with H. pylori infection in a consecutive series of 2,195 asymptomatic average-risk subjects who(More)
OBJECTIVES This study aimed to determine longterm outcomes and factors associated with increased survival after photodynamic therapy (PDT) compared with endoscopic biliary drainage alone in patients presenting with advanced hilar cholangiocarcinoma (CC). METHODS A retrospective analysis of the institutional database identifying all patients who presented(More)
Wound healing occurs in three sequential phases: hemostasis and inflammation, proliferation, and remodeling. Inflammation, the earliest phase, is considered a critical period for wound healing because immune cells remove damaged tissues, foreign debris, and remaining dead tissue. Wound healing would be delayed without inflammation, and this phase is(More)
This study was performed to investigate the association between hair mineral levels and nutrient intakes, age, and BMI in female adults who visited a woman's clinic located in Seoul. Dietary intakes were assessed by food frequency questionnaire and mineral levels were measured in collected hairs, and the relationship between these was examined. The average(More)
In this study, the protective effects of melatonin were evaluated against 3-nitropropionic acid (3-NP)-induced striatal neuronal damage in rats. Lesions were induced in the right striatum of Sprague-Dawley rats by stereotaxic injection with 3-NP and melatonin was intraperitoneally administered both 30 min before and 60 min after 3-NP injection. And rats(More)
We propose the idea of single cell dielectric spectroscopy for future clinical applications such as cell therapy and regen-erative medicine. The structure of the microfluidic device is carefully designed to suppress the influence of electrode polarization on the dielectric spectra of single cells. Beads of uniform size distribution is used to determine the(More)
BACKGROUND/AIMS The prevalence of nonalcoholic fatty liver disease (NAFLD) in Korea has increased recently. The aim of the present study was to determine the regional differences in the prevalence and characteristics of NAFLD. METHODS From January 2009 to December 2010, 161,891 Seoul and Gyeonggi-do residents receiving a health examination at our(More)
Cordyceps militaris is a mushroom traditionally used for diverse pharmaceutical purposes in East Asia, including China, and has been found to be effective for enhancing immunity through various types of animal testing. The aim of this study is to determine the efficacy of C. militaris for enhancing cell-mediated immunity and its safety in healthy male(More)
The technology for measuring ECG using capacitive electrodes and its applications are reviewed. Capacitive electrodes are built with a high-input-impedance preamplifier and a shield on their rear side. Guarding and driving ground are used to reduce noise. An analysis of the intrinsic noise shows that the thermal noise caused by the resistance in the(More)
PURPOSE To investigate the intravitreal toxicity and pharmacokinetics of candesartan, a selective type 1 angiotensin II receptor blocker, in rabbit eyes. METHODS For the toxicity study, 15 white rabbits were divided into three groups (five rabbits each). Different candesartan doses, namely 0.5, 1, and 2 mg in 0.1 mL, were injected into the vitreous of the(More)
