Investigators To Present New Study Results and Discuss Clinical Benefit for GI patients with Eosinophilic Esophagitis, IBD, polyps, HIV, spirochetosis and H. pylori. Irving, Texas (PRWEB) September 25, 2013 Findings from seven research studies conducted by the Miraca Life Sciences Research Institute have been selected for presentation at this year’s American College of Gastroenterology annual scientific meeting. Beginning Sunday, October 13, 2013 through Tuesday, October 15, attendees...

Researchers have identified cells in the immune system that react to the stomach ulcer bacterium Helicobacter pylori, one of the risk factors for the development of stomach cancer. This discovery could lead to faster diagnosis and treatment as well as a better prognosis for patients with stomach cancer, reveals a thesis from the University of Gothenburg, Sweden. Helicobacter pylori is one of the most common bacterial infections in the world, and leads to chronic inflammation of the stomach....

Atrophic gastritis and intestinal metaplasia are two important precursory lesions in the process of intestinal type gastric cancer. However, the precise mechanism of the progression of these two lesions is still unclear, a few studies have investigated the risk of host gene polymorphism on the atrophic gastritis and intestinal metaplasia, but all of them are limited by their one-time point screen. A research article to be published on April 14, 2010 in the World Journal of Gastroenterology...

The clinical outcome of gastric disease may involve differences in the prevalence or expression of bacterial virulence factors. Contrary to Asian studies, Western studies have disclosed associations between the presence of babA2 gene and gastric cancer. Evidence concerning BabA adhesin-associated genes is insufficient in Costa Rica, where the incidence of gastric cancer is very high, similar to Japan. The babA2 gene, which encodes BabA, may play a role in the development of gastric cancer in...

Experimental animal studies have shown that H. pylori shares several antigenic regions in common with acid secreting cells in gastric mucosa. Antibodies triggered by H. pylori destroy acid secreting cells due this antigenic mimicry. H. pylori infection is very common in humans, and about half of the infected patients develop atrophic changes over the years. In end stage severe atrophy, H. pylori disappears and signs of a previous infection are difficult to detect. This research, lead by Dr. L...

U.S. scientists say they've determined both an overabundance and a lack of the hormone gastrin play key rolls in bacterial-induced stomach cancer. More than 50 percent of the world's population is infected with Helicobacter pylori, which is strongly linked to the development of gastric ulcers and stomach cancer, researchers said. Helicobacter infection results in increased expression of gastrin, a hormone that stimulates secretion of gastric acid, However, the role of gastrin in cancer...

A group led by Columbia University Medical Center's Timothy Wang, M.D., has studied the role of Helicobacter infection in the development of stomach cancer and found that the hormone gastrin, which stimulates secretion of gastric acid, plays a key role in the development of Helicobacter-induced stomach cancer, and may have distinct effects on carcinogenesis in different parts of the stomach.More than 50 percent of the world's population is infected with Helicobacter, which causes chronic...

Gastric cancer (GC) is the fourth most common malignancy and the second most frequent cause of cancer-related death in the world. The carcinogenesis of GC involved numerous genetic and epigenetic alterations, as well as many environmental risk factors. Environmental pollutants such as polycyclic aromatic hydrocarbons (PAHs) and halogenated hydrocarbons (HAHs) are well-known carcinogens that play important roles in GC development. The toxic effects of PAHs and HAHs are mediated by a conserved...

By Sepulveda, Antonia R Patil, Madhavi Context.-Most types of gastritis can be diagnosed on hematoxylin- eosin stains. The most common type of chronic gastritis is Helicobacter pylori gastritis. Reactive or chemical gastropathy, which is often associated with nonsteroidal anti-inflammatory drug use or bile reflux, is common in most practices. The diagnosis of atrophic gastritis can be challenging if few biopsy samples are available and if the location of the biopsies in the stomach is not...
