BACKGROUND & AIMS Sequential therapy with a proton pump inhibitor (PPI) and amoxicillin followed by a PPI, clarithromycin, and an imidazole agent reportedly have a better rate of curing Helicobacter pylori infection than PPI, amoxicillin, and clarithromycin triple therapy. The concomitant administration of these 4 drugs (concomitant therapy) is also an(More)
OBJECTIVES This prospective study was designed to determine the efficacy of a levofloxacin-based rescue therapy for Helicobacter pylori infection after failure of standard triple therapies. We also surveyed the predictors of this rescue therapy. PATIENTS AND METHODS From June 2005 to March 2007, 1036 patients infected with H. pylori received standard(More)
OBJECTIVE In patients with cirrhosis and spontaneous bacterial peritonitis (SBP), the use of intravenous albumin has been shown to prevent deterioration of renal function and to decrease the mortality rate, but the mechanisms remain unclear. The purpose of this study was to characterize the mechanisms of action of albumin with the focus on endotoxin and(More)
Inhibiting the expression of the HIV-1 coreceptor CCR5 holds great promise for controlling HIV-1 infection in patients. Here we report stable knockdown of human CCR5 by a short hairpin RNA (shRNA) in a humanized bone marrow/liver/thymus (BLT) mouse model. We delivered a potent shRNA against CCR5 into human fetal liver-derived CD34(+) hematopoietic(More)
BACKGROUND Recent studies suggest that cetraxate possesses anti-Helicobacter pylori (H. pylori) activity. We therefore conducted this pilot study to investigate the efficacy of a cetraxate-based triple therapy and to compare the regimen with proton pump inhibitor-based triple therapy. METHODS From April 2001 to January 2002, a total of 58 H.(More)
Embryonic hematopoiesis starts via the generation of primitive red blood cells (RBCs) that satisfy the embryo's immediate oxygen needs. Although primitive RBCs were thought to retain their nuclei, recent studies have shown that primitive RBCs in mice enucleate in the fetal liver. It has been unknown whether human primitive RBCs enucleate, and what(More)
It is known that Fas death domain-associated protein (Daxx) possesses both putative nuclear and cytoplasmic functions. However, the nuclear transport mechanism is largely unknown. This study examined the nuclear location signal (NLS) of Daxx and whether the nuclear transport of Daxx was mediated by small ubiquitin-related modifier (SUMO). Two NLS motifs of(More)
GOAL Study the mechanism of gastric tumor development. BACKGROUND We have generated and characterized a novel human gastric cell line, KMU-CS12 (CS12), from an immortal cell line, KMU-CSN (CSN; formerly named as GI2CS) which was derived from putative human gastric stem cell/progenitor cell clone, KMU-GI2. STUDY The characterization of the CS12 cell line(More)
With the rising prevalence of antimicrobial resistance, the failure rate of the standard triple therapy for Helicobacter pylori infection is increasing. Sequential therapy and concomitant therapy have been recommended to replace standard triple therapy for H. pylori eradication in regions with high clarithromycin resistance. The aim of this prospective,(More)
