An RNA virus, designated hepatitis G virus (HGV), was identified from the plasma of a patient with chronic hepatitis. Extension from an immunoreactive complementary DNA clone yielded the entire genome (9392 nucleotides) encoding a polyprotein of 2873 amino acids. The virus is closely related to GB virus C (GBV-C) and distantly related to hepatitis C virus,(More)
BACKGROUND The role of hepatitis G virus (HGV) in transfusion-associated infection and its relation to liver disease are not well understood. METHODS Serum samples collected between 1972 and 1995 from 357 transfusion recipients, 157 controls who did not receive transfusions, 500 randomly selected volunteer blood donors, and 230 donors of blood received by(More)
The gene encoding Plasmodium vivax circumsporozoite protein (PvCSP) exhibits polymorphism in many geographical isolates. The present study was designed to investigate polymorphism in PvCSP gene of P. vivax isolates in Korea. Thirty isolates, obtained from indigenous cases in Yonchon-gun, Kyonggi-do in 1997, were subjected for sequencing and RFLP analysis of(More)
A retrospective analysis of 3,702 gastric cancer patients operated on between 1981 and 1991 was carried out to compare the clinicopathological features of signet ring cell (SRC) gastric cancer with other cell types. Four hundred and fifty patients (12.2%) had signet ring cell gastric carcinoma. There was a tendency for patients with the signet ring cell(More)
BACKGROUND It is not clear whether dabigatran is as safe and effective as uninterrupted anticoagulation with warfarin during radiofrequency catheter ablation (RFA) of atrial fibrillation (AF). OBJECTIVE To compare the safety and efficacy of dabigatran by using a novel administration protocol and uninterrupted anticoagulation with warfarin for(More)
Major epidemic outbreaks of viral hepatitis in underdeveloped countries result from a type of non-A, non-B hepatitis distinct from the parenterally transmitted form. The viral agent responsible for this form of epidemic, or enterically transmitted non-A, non-B hepatitis (ET-NANBH), has been serially transmitted in cynomolgus macaques (cynos) and has(More)
UNLABELLED A reverse transcriptase-polymerase chain reaction procedure (RT-PCR) for the detection of hepatitis G virus (HGV) RNA was used to examine the prevalence of HGV infection and HGV-related disease in Japan. Among 48 patients with acute non-A, B, C, D, E (non-A-E) hepatitis (five transfusion-associated cases and 43 sporadic cases), only one patient(More)
We report 8 newly established gastric-carcinoma cell lines (SNU-216, 484, 520, 601, 620, 638, 668, 719) from Korean patients. Morphologic study was carried out using light and electron microscopes. CEA, alpha FP, and CA 19-9 and TPA in supernatant and in cell lysate were measured by radioimmunoassay. p53 and c-Ki-ras gene mutations were screened and(More)
The migration of human keratinocytes across the would bed is an early and critical event in the reepithelialization of cutaneous wounds. Epidermal growth factor (EGF) has been shown to accelerate the healing of fresh, split-thickness cutaneous wounds when applied topically. The mechanism(s) by which this accelerated healing occurs remains unknown. Using an(More)
Norwalk virus, an important cause of epidemic, acute, nonbacterial gastroenteritis in adults and children, has eluded adaptation to tissue culture, the development of an animal model, and molecular cloning. In this study, a portion of the Norwalk viral genome encoding an immunoreactive region was cloned from very small quantities of infected stool using(More)
