Background: Many recent studies have examined potential risk factors of H. pylori gastritis to improve our understanding of the early events in gastric carcinogenesis. We evaluated the extent and topography of chronic gastritis in a high risk area for gastric cardia cancer and investigated the critical role of H.pylori, risk index and age in its pathogenesis. Materials and Methods: During a na...

Background: Differentiating oligodendrocyte precursor cells (OPCs) into oligodendrocytes could be improved by inhibiting signaling pathways such as Wnt and Notch. 9-cis-retinoic acid (9-cis-RA) and 1,25-dihydroxyvitamin D3 (1,25[OH]2D3) can ameliorate oligodendrogenesis. We investigated whether they could increase oligodendrogenesis by inhibiting the Wnt and Notch signaling pathways.Methods: Co...
abstract introduction : conjugated linoleic acid (cla) has been shown to positively influence on calcium and bone metabolism in experimental animals and cell culture, but there are limited human data available. material and methods : this double-blind, placebo-controlled trial study was done on 76 healthy post-menopausal women (aged 55.1) which randomly assigned to receive daily four cla capsul...
Abstract Background: Most animal studies have shown that trans-10 and cis-12 isomers of Conjugated linoleic Acid, (CLA) tend to increase insulin resistance. But the effect of equal isomers of CLA (50:50 ratios of cis-9, trans-11: trans-10, cis-12 isomers) on lipid profiles, glucose, and insulin resistance and sensitivity in postmenopausal women is not clear. Methods: In the present study, ...
dear editor multiple sclerosis (ms) is the most common inflammatory demyelinating disease of the central nervous system. ms is characterized by dissemination in time and place. dissemination can be clinically (clinically definite multiple sclerosis) or radiologically by magnetic resonance imaging (mri). correct diagnosis of ms needs dissemination both in time and in place and also exclusion of ...
in 1998, international council on archives emphasized on setting up a database on archival issues in the cis countries and produced a mechanism in this regard. an exhaustive questionnaire was provided and the countries struck out on collecting data from ten cis countries. the result of an analysis of the questionnaires was published in a book, namely archival issues in the cis states. now, eac...
Background: Variability in speech performance is a major concern for children with cochlear implants (CIs). Spectral resolution is an important acoustic component in speech perception. Considerable variability and limitations of spectral resolution in children with CIs may lead to individual differences in speech performance. The aim of this study was to assess the correlation between auditory ...
