The microorganism now known as Helicobacter pylori is considered to be an important factor in the etiology of peptic ulcers. It can secrete urease enzyme and buffer gastric acids to survive in the stomach. H. pylori can colonize the gastric mucosa and preferentially adheres near the cell-cell junctions of the gastric mucous cells. In this study,(More)
Many studies indicated that small mammals are important reservoirs for Bartonella species. Using molecular methods, several studies have documented that bats could harbor Bartonella. This study was conducted to investigate the relationship of Bartonella spp. identified in bats and small mammals living in the same ecological environment. During May 2009 and(More)
The emergence of ciprofloxacin-resistant Salmonella enterica serovar Choleraesuis in recent years has become an important public health issue in Taiwan. The resistant strains that cause human infections are considered to be from pigs. In this study, we characterized 157 swine and 42 human Salmonella serovar Choleraesuis isolates by pulsed-field gel(More)
—In March and April 2009, an outbreak of H1N1 influenza in Mexico led to hundreds of confirmed cases and a number of deaths. The worldwide spread of H1N1 had attracted everyone's attention and arisen an overwhelm fear. Up to now, there is still an urgent need in the solution for ending this fight. In this study, a QSAR model of neuraminidase (NA) type 1(More)
Epigallocatechin gallate (EGCG) is a green tea polyphenol that presents anticancer activities in multiple cancer cells, but no available report was addressed for the underling molecular mechanism of cytotoxic impacts on drug-resistant oral squamous cell carcinoma cells. In the present study, the inhibitory effects of EGCG were experienced on(More)
Helicobacter pylori infection is associated with chronic gastritis, peptic ulcers, and gastric cancer. The effects of Solanum lyratum extract (SLE) on anti-H. pylori activity and H. pylori-induced apoptosis were investigated. SLE showed a moderate ability in inhibiting growth of H. pylori and also in interrupting the association of bacteria with host cells.(More)
Helicobacter pylori infection is thought to be involved in the development of several gastric diseases. Two H. pylori virulence factors (vacuolating cytotoxin A and cytotoxin-associated gene A) reportedly interact with lipid rafts in gastric epithelial cells. The role of Toll-like receptor (TLR)-mediated signaling in response to H. pylori infection has been(More)
OBJECTIVE To investigate a nosocomial outbreak of infection with multidrug-resistant (MDR) Acinetobacter baumannii in the intensive care units at China Medical University Hospital in Taiwan. DESIGN Prospective outbreak investigation. SETTING Three intensive care units in a 2,000-bed university hospital in Taichung, Taiwan. METHODS Thirty-eight stable(More)
In this study, 18 Avibacterium paragallinarum isolates collected in Taiwan from 1990 to 2003 were serotyped and tested for resistance to antimicrobial agents. Serotyping revealed that 13 isolates were Page serovar A and 5 isolates were Page serovar C. More than 75% of the isolates were resistant to neomycin, streptomycin and erythromycin. The most common(More)
Phenethyl isothiocyanate (PEITC), one of the major compounds from dietary cruciferous vegetables, has been found to have antitumor properties and therefore could generate special interest for the development of chemopreventive and/or chemotherapeutic agent for human cancers. In the primary studies, we found that PEITC induced cytotoxic effect (decreased the(More)
