Abstract Background In general, all virulence factors of Helicobacter pylori ( H. pylori) are involved in its infections. However, recent studies have shown that the homB gene is one genes affects severity clinical results this bacterium. Methods The main purpose study was to investigate relationship between presence and progression infection peptic ulcer gastric cancer. present study, we condu...

Atmospheric impairments are a major obstacle in satellite communications at Ka-band in high latitude regions. This report gives a short summary of the existing models that can be used to model the impairments. Further a simple measurement system based on satellite beacon reception is designed using locally available and off-the-shelf components as well as locally manufactured ones. Performance ...

background : helicobacter pylori is a major human gastric for various gastro duodenal diseases.a number of putative virulence factors such as dupa, homb, tnpa have been described. to date,none were found to be significantly associated with specific h. pylori-related diseases (e.g. gastric cancer and duodenal ulcer). methods : the primary aim of this study was to test the h. pylori hrga genotype...

Infection with Helicobacter pylori is the major cause for the development of peptic ulcer disease (PUD). In children, with no other etiology for the disease, this rare event occurs shortly after infection. In these young patients, habits of smoking, diet, consumption of alcohol and non-steroid anti-inflammatory drugs and stress, in addition to the genetic susceptibility of the patient, represen...

The object of this paper is to study the relationship between certain projective modules and their endomorphism rings. Specifically, the basic problem is to describe the projective modules whose endomorphism rings are (von Neumann) regular, local semiperfect, or left perfect. Call a projective module regular if every cyclic submodule is a direct summand. Thus a ring is a regular module if it is...
