In the presence of obesity, beta-cell mass needs to be increased to compensate for the accompanying demands and maintain euglycemia. However, in Korea, the majority of type 2 diabetic patients are nonobese. We determined the absolute masses, relative volumes, and ratio of alpha- and beta-cell in the pancreas and islets in normal and diabetic Korean subjects(More)
Glucocorticoids stabilize the blood-brain barrier (BBB), leading to attenuation of vasogenic brain edema. However, the action mechanism of glucocorticoids has been poorly elucidated. To elucidate the mechanism, we investigated whether dexamethasone (Dex), a synthetic glucocorticoid hormone, regulates the levels of key permeability regulating factors such as(More)
BACKGROUND/AIMS During the natural course of hepatitis B virus (HBV) infection, the long-term clinical and histological outcomes following spontaneous hepatitis B surface antigen (HBsAg) seroclearance remain unclear. METHODS Between 1984 and 2003, 49 (9.5%) out of 432 inactive HBsAg carriers had no detectable level of circulating HBsAg. Fifteen of 49(More)
Ascites is the most common complication of liver cirrhosis, and it develops as a consequence of portal hypertension and splanchnic vasodilatation. Depending on severity, management of ascites consists of diverse strategy, including dietary sodium restriction, diuretic therapy, repeated large-volume paracentesis with albumin infusion, transjugular(More)
Fusaricidins produced by Paenibacillus polymyxa DBB1709 are lipopeptide antibiotics active against fungi and Gram-positive bacteria. The cyclic hexapeptide structures of fusaricidins are synthesized by fusaricidin synthetase, a non-ribosomal peptide synthetase. The adenylation domain of the third module (FusA-A3) can recruit l-Tyr, l-Val, l-Ile, l-allo-Ile,(More)
Mesenchymal stem cells (MSCs) are powerful sources for cell therapy in regenerative medicine because they can be isolated from various tissues, expanded, and induced into multiple-lineages. Of note, their immunomodulatory effects maximize the therapeutic effects of stem cells engrafted on host, making them an especially attractive choice. Recently, several(More)
BACKGROUND Large clinical studies assessing long-term adefovir dipivoxil salvage monotherapy in patients with lamivudine-resistant chronic hepatitis B (CHB) are lacking, particularly in patients positive for hepatitis B e antigen (HBeAg). We assessed the efficacy and resistance profile of adefovir dipivoxil monotherapy for up to 5 years in a large cohort of(More)
BACKGROUND The aim of this study was to analyze the prevalence and clinical characteristic of the metabolic syndrome of adults, over 40 years old, living in Korea. METHODS This study was carried out for 2 years, 2003-2004, on total 5,330 individuals (2,197 men and 3,133 women) selected by the stratified random cluster sampling among adults over 40 years(More)
A bifunctional alcohol/acetaldehyde dehydrogenase (AdhE) gene (adhE) was cloned from Leuconostoc mesenteroides C7 (LMC7), which is the dominant lactic acid bacterium produced during heterofermentation of kimchi. The nucleotide sequence of the DNA fragment containing putative adhE, which is 2685 bp long and encodes an 886 amino acid polypeptide, exhibits 99%(More)
UNLABELLED Quantitative hepatitis B surface antigen (qHBsAg) and quantitative hepatitis B e antigen (qHBeAg) titers are emerging as useful tools for measuring viral loads and for predicting the virological response (VR) and serological response (SR) to pegylated interferon therapy. However, the clinical utility of these assays in patients taking entecavir(More)
