It has been shown that resistance to clarithromycin, a major cause of failure in Helicobacter pylori eradication therapy, is associated with point mutations in the 23S rRNA gene. We sought to apply...

Quantitative Effect of luxS Gene Inactivation on the Fitness of Helicobacter pylori▿
Lee, Woo-Kon, Ogura, Keiji, Loh, John T., Cover, Timothy L., Berg, Douglas E.
Furanone metabolites called AI-2 (autoinducer 2), used by some bacterial species for signaling and cell density-regulated changes in gene expression, are made while regenerating S-adenosyl methionine...
Virulence Factors of Helicobacter pylori Responsible for Gastric Diseases in Mongolian Gerbil
Ogura, Keiji, Maeda, Shin, Nakao, Masafumi, Watanabe, Takeshi, Tada, Mayumi, Kyutoku, Toshimasa, ...
Helicobacter pylori infection induces various gastroduodenal diseases. We examined the role of two genes, vacA and cagE, in the gastric pathogenesis induced by H. pylori using a long-term (62 wk)...

The Mongolian gerbil model of Helicobacter pylori infection resembles human gastritis. In this study, we investigated the role of NF-κB activation in H. pylori-infected gerbils. Activated...
A case of rectal Dieulafoy’s ulcer and successful endoscopic band ligation
Yoshikumi, Yukako, Mashima, Hirosato, Suzuki, Junko, Yamaji, Yutaka, Okamoto, Makoto, Ogura, Keiji, ...
Dieulafoy’s ulcer is a rare cause of gastrointestinal bleeding. The lesion is usually located in the stomach, although it may occur anywhere in the gastrointestinal tract. A 44-year-old man was...
