Despite the clinical importance of Helicobacter pylori in human gastric disorders, its exact route of transmission is still uncertain. Based on the contentious hypothesis and findings of previous investigations, water may play an important role in the transmission of H. pylori to humans. This study was carried out to investigate the vacA, cagA, oipA, iceA and babA2 genotype status and antimicro...

Aim This study was aimed to investigate the presence of H. pylori and its virulence genotypes in dental plaques of Iranian patients with chronic periodontitis. Background Helicobacter pylori is a Gram-negative bacterium that is associated with atrophic gastritis, peptic ulcer, and gastric cancer. Several studies have detected this bacterium in the oral cavity, suggesting it as a potential res...

زمینه و هدف: کم‌تحرکی در مقابل آن تمرین جزء عوامل مرتبط با شاخص‌های آسیب کبدی به‌شمار می‌روند. وجود این هنوز نقش بسیاری از تمرین‌های ورزشی به‌ویژه تمرینات تناوبی مقاومتی مصرف برخی مکمل‌های غذایی جمله اسپیرولینا بر ایمنی التهابی کاملاٌ شناخته نشده است؛ بنابراین هدف پژوهش تعیین اثر هشت هفته مکمل‌دهی هوازی فعالیت بافت کبد بیان ژن CXCL1 عضلة موش‌های صحرایی نر بود.مواد روش‌ها: نیمه‌تجربی، 60 سر موش ن...

BACKGROUND The prevalence of H. pylori is as high as 60-70% in Chinese population. Although duodenal ulcer and gastric cancer are both caused by H. pylori, they are at opposite ends of the spectrum and as such are considered mutually exclusive. Duodenal ulcer promoting (dupA) gene was reported to be associated with duodenal ulcer development. The aim of this study was to determine the prevalenc...

BACKGROUND: The clinical outcome of Helicobacter pylori infection has been associated with virulence factors. The presence of these factors is useful as molecular markers in the identification of the high risk for developing severe gastric pathologies. OBJECTIVE: To correlate the presence of virulence markers cagA and bab2A of H. pylori in oral and gastric biopsy samples. METHODS: An observ...

Helicobacter pylori (H. pylori) infection has been reported in more than half of the world human population. It is associated with gastric inflammation and noticeable infiltration of the immune cells to the stomach mucosa by several cytokines secretion. IL-1β, IL-18 have been shown to contribute to H. pylori induced gastritis, but the details of inflammation and association of virulence factors...

We have read with interest the article entitled “cagE as a biomarker of the pathogenicity of Helicobacter pylori" by Ramis et al.1. In this study, with a sample size of 57, the authors suggested that cagE is an important prognostic indicator for developing lesions during Helicobacter pylori infection. This suggestion was based on the fact that a statistically signifi cant association was found ...
