BACKGROUND Use of the conventional Western and Japanese classification systems of gastrointestinal epithelial neoplasia results in large differences among pathologists in the diagnosis of oesophageal, gastric, and colorectal neoplastic lesions. AIM To develop common worldwide terminology for gastrointestinal epithelial neoplasia. METHODS Thirty one(More)
1. The intrinsic electrical properties of human neocortical neurons were studied with current-clamp and single-electrode voltage-clamp techniques in slices obtained from children, aged 3 mo to 15 yr, undergoing surgical treatment of intractable epilepsy. Neocortical samples were classified as most or least abnormal based on clinical data. Recorded neurons(More)
BACKGROUND Although mucin expressions appear to be correlated with prognoses in patients with various cancers, several studies have reported conflicting and inconclusive results on the prognostic significance of mucin expression in gastric carcinomas. METHODS To clarify the correlations between clinicopathologic profiles and the patients' survival, the(More)
1. The electrophysiological properties of suprachiasmatic nucleus (SCN) neurons (n = 33) receiving optic nerve input were studied with intracellular recordings in rat hypothalamic slices maintained in vitro. Our major goal was to provide baseline data concerning the intrinsic membrane properties of these neurons and to test the hypothesis that the neurons(More)
A study was conducted to determine the effect of broiler poultry litter (BL) supplementation to spent mushroom substrate (SMS) on its storage and feed-nutritional value improvement. In Exp. 1, the sawdust-based SMS from a king oyster mushroom (Pleurotus eryngii) farm was mixed with BL at 0%, 25%, 50%, 75% and 100% levels on a wet basis and deepstack stored(More)
Currently available evidence from epidemiologic, animal, and intervention studies does not unequivocally support the role of folate, a water-soluble B vitamin and important cofactor in one-carbon transfer, in the development and progression of colorectal cancer (CRC). However, when the portfolio of evidence from these studies is analyzed critically, the(More)
It has previously been shown that choline deficiency causes depletion of hepatic folate concentration in rats. Two separate experiments were undertaken to investigate the converse phenomenon: whether folate deficiency would lead to depletion of hepatic choline. In Experiment 1, severe folate deficiency was induced in rats by feeding an amino acid-defined(More)
Epidemiological and animal studies (reviewed in Y. I. Kim, J. Nutr. Biochemistry, 10: 66-88, 1999; J. B. Mason and T. Levesque, Oncology, 10: 1727-1743, 1996) suggest that dietary folate intake is inversely related to the risk of colorectal cancer. However, the optimal timing of folate intervention and mechanisms by which folate modulates colorectal(More)
BACKGROUND AND AIMS Diminished folate status is associated with enhanced colorectal carcinogenesis. This study investigated the potential chemopreventive role of dietary folate in the dimethylhydrazine colorectal cancer model. SUBJECTS AND METHODS Sprague-Dawley rats were fed diets containing either 0, 2 (daily dietary requirement), 8 or 40 mg folate/kg(More)
The risk of locoregional recurrence in resected gastric adenocarcinoma is high, but the benefit of adjuvant treatment remains controversial. In particular, after extended lymph node dissection, the role of radiotherapy is questionable. Since 1995, we started a clinical protocol of adjuvant chemoradiotherapy after D2 gastrectomy and analysed the patterns of(More)
