OBJECTIVE Recent studies have shown the correlation between vertebral fractures (VFs) and gastrointestinal disorders in postmenopausal women. The aim of this study was to assess the association between VFs and hiatal hernia (HH) and/or reflux esophagitis (RE) in our patient population of both men and women. METHODS We analyzed retrospective data of 280(More)
BACKGROUND A number of diseases and drugs may influence bone mineral density; however, there are few reports concerning the relationship between lifestyle-related diseases and osteoporosis in Japan as determined by multivariate analysis. The aim of this study was to investigate the risk factors for osteoporosis and whether infection by or eradication of(More)
AIMS The aim of this study is to investigate the expression and cytoprotective function of a 72-kDa heat shock protein (HSP72) using a reflux esophagitis model in rats. MAIN METHODS Expression of HSP60, HSP72, and HSP90 in rat esophageal mucosa was evaluated by Western blot analysis before and after hyperthermia (42.5 degrees C, 20 min). Rats received the(More)
Background and Objective. H. pylori infection causes a chronic inflammation in the gastric mucosa. However, this local inflammation may result in extra-digestive conditions. Our aim is to investigate the relationship between H. pylori infection and osteoporosis in Japan. Methods. This cross-sectional study was conducted among outpatients at the Juntendo(More)
In recent years, many accounting scandals have been reported in companies not only in the United States, but also in Japan. The need for Internal Control is thus growing steadily. In particular, auditing logs are important for Internal Control, although without an audit function, any Internal Control is incomplete. The cost of an information system is(More)
BACKGROUND AND AIMS It is still controversial which drugs, proton pump inhibitors (PPI) or histamine-2 receptor antagonists (H2RA), are more effective for dyspepsia in the Japanese population. METHODS Patients with uninvestigated dyspepsia (n = 104; male/female 41/63) were treated with either rabeprazole 10 mg o.d. (n = 62) or lafutidine 10 mg b.i.d. (n =(More)
In recent years, many accounting scandals have been reported in companies not only in the United States, but also in Japan. The need for Internal Control is growing steadily. In particular, auditing logs is important for Internal Control. Internal Control lacking audit is incomplete. In addition, logs are included not only defensive implication but also a(More)
AIM Recent reports have indicated that aldo-keto reductase family 1 member B10 (AKR1B10), a cancer-related oxidoreductase, was upregulated in some chronic liver diseases. However, few studies have reported AKR1B10 expression in chronic hepatitis B virus (HBV)-infected patients. The aim of the present study was to analyze AKR1B10 expression and its relevance(More)
Background. We investigated the prevalence, symptoms, and QOL impact of esophageal (EI), gastric (GI), and duodenal mucosal injury (DI) individually between low-dose aspirin (LDA) users and nonusers to reveal the clinical features of LDA-related mucosal injury. Methods. Data were extracted from the records of subjects who underwent upper gastrointestinal(More)
AIMS Several recent studies, including ours, have indicated the importance of heat shock proteins (HSPs) in cytoprotection against cytotoxic agents and environmental stresses mediated by the chaperone function of HSPs (molecular chaperones). However, the target molecule that is recognized by HSPs in damaged cells currently remains unknown. As HSPs rapidly(More)
