The incidence of a certain type of gastric cancer has declined in the last 30 years for all age groups and races, except for whites 25 to 39 years of age, according to a study in the May 5 issue of JAMA. Gastric cancer is the fourth most common type of cancer and the second most common among cancer deaths worldwide. While tumors of the cardia, the upper part of the stomach adjoining the esophagus, may be related to gastroesophageal reflux, the majority of noncardia gastric cancers are...

Patients who have gastric cancer surgery followed by chemotherapy have an associated decreased risk of death and improved disease-free survival compared to patients who have surgery alone, according to an analysis of previous studies, reported in the May 5 issue of JAMA. Gastric cancer is a common and highly fatal disease, with current 5-year survival rates less than 20 percent, according to background information in the article. "Surgery for disease at an early stage can usually be performed...

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...

A Kansas State University study aimed at alleviating intestinal damage in trauma patients digressed to an important finding that could affect medication given to the individuals. Diana Hylton is a K-State senior in microbiology, nutritional sciences and pre-medicine. She is analyzing how the immune system is involved in damage to the intestines following hemorrhagic shock. While studying the effects of a complement inhibitor given following hemorrhage, she found that Helicobacter infection...

Max Planck scientists succeed with a novel technique in the fight against the cause of peptic ulcer disease and gastric cancer A breakthrough in decoding gene regulation of Helicobacter pylori has been made by an international research team led by Jörg Vogel of the Max Planck Institute for Infection Biology in Berlin. Using a newly developed sequencing technique, the re-searchers discovered 60 small ribonucleic acids (sRNAs) - tiny RNA-particles which can regulate genes - in the genome...

Helicobacter pylori (H. pylori) is the causal agent of chronic gastritis, ulcer and gastric cancer. It has the potential to persist in the human stomach for decades, sometimes causing neither harm nor clinical symptoms. Nevertheless, on some occasions, depending on the host immune system and the strain causing the infection, the outcome can be very serious. To maintain the infection, the bacterium must adapt to survive the host defences. One way to accomplish this is to sequentially change...

Gastric cancer, one of the most common types of cancer, is associated with high mortality rates. In the last decades, a decrease in the worldwide incidence has been observed with some changes in the therapeutic and diagnostic options. However, the prognosis for this disease still remains poor, mainly when the diagnosis is performed at advanced stages. The therapy most effective is still surgical resection and in a significant number of cases, especially in the advanced stage, it is only...

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...

Helicobacter pylori (H. pylori) are considered to be the most important etiological agents of chronic gastritis. The eradication of H. pyloridepends on the combination of antibiotics and acid suppression drugs. Unfortunately, the side effects of antibiotics reduce the curative effect and treatment compliance. Probiotics provides an alternative method which can inhibit H. pylori infection efficiently without antibiotics associated side effects. A research team from China investigated the...

Despite a strong response from our immune defense, the body is unable to rid itself of the bacterium Helicobacter pylori. One reason for this is that this bacterium encourages elements of the immune response to remain in tissue, activating the wrong immune cells. Research results that pave the way for a future vaccine are now being published by the Sahlgrenska Academy at the University of Gothenburg, Sweden. Approximately half of the world's population are infected with Helicobacter pylori,...

Helicobacter pylori is a Gram-negative, microaerophilic bacterium that can inhabit various areas of the stomach, particularly the antrum. It causes low-level inflammation of the stomach lining and is linked to gastric ulcers and stomach cancer. Out of those infected, 80%, are asymptomatic. It was initially named Campyloacter pyloridis and then renamed C. pylori to correct the Latin grammar error. It was later placed in the genus, Helicobacter. Over 50% of the population has H. pylori in...

  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED.
