The aim of this study was to assess the genetic status of cagA, vacA subtype and iceA genotypes of Helicobacter pylori and the relationship with upper gastrointestinal diseases in Northeast China. Gastric biopsies were obtained from 378 patients with upper gastrointestinal diseases and 197 samples were used. The cagA, vacA alleles and iceA genotypes were determined by polymerase chain reaction....

The clinical outcome of Helicobacter pylori infection has been particularly associated with virulence genotypes. These genotypes are useful as molecular markers in the identification of patients that are infected and at high risk for developing more severe gastric pathologies. Our main objective was to determine the prevalence of virulence genotypes cagA, vacA, iceA and babA2 of H. pylori, in p...

Helicobacter pylori is a Gram-negative human gastric pathogen which has a possible etiologic role in peptic and gastric ulcers, gastric adenocarcinoma and more rarely, lymphoma of the mucosa-associated lymphoid tissue. The pathogenicity of H. pylori is intimately associated with the expression of virulence factors such as urease, cagA, iceA, vacA and bacterial adhesion and maintenance factors. ...

Pro-inflammatory Interleukin-1 receptor antagonist (IL-1RN) gene polymorphism and high risk Helicobacter pylori virulence factors in combination plays an important role in the outcome of H. pylori associated diseases, which can even lead to gastric cancer. The purpose of this study was to analyze the prevalence of high risk host and bacterial factors such as IL-1RN gene variable number tandem r...

OBJECTIVE To determine the prevalence of cagA+ and iceA genotypes among Helicobacter pylori (H. pylori) isolates from a group of Saudi patients with gastric complaints, and to find out any significant correlation between these strains and severe gastric clinical outcomes such as peptic ulcer and gastric cancer in Saudi population. METHODS A total of 1104 gastric biopsies from 368 patients who...

This report analyses the aplicability of the principles of consciousness developed in the ICEA project to three of the most relevant cognitive architectures. This is done in relation to their aplicability to build integrated control systems and studying their support for general mechanisms of real-time consciousness. To analyse these architectures the ASys Framework is employed. This is a conce...

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...

Industry standards for shielded medium-voltage cables (5–46 kV) have recently been revised, changing the dc test voltages for field tests and test durations and limiting tests to newly installed cables. The following industry groups’ specifications and standards provide different guidelines for dc field tests for cross-linked polyethylene and ethylene propylene rubber insulated cables: IEEE, In...
