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,...

It's been implicated as the bacterium that causes ulcers and the majority of stomach cancers, but studies by researchers at Stanford University, UC Davis, and the University of Pittsburgh have found that Helicobacter pylori (H. pylori) also may play a protective role "“ against the worldwide killer, tuberculosis (TB). In an article appearing online Wednesday in PloS ONE, Jay Solnick, UC Davis professor of medicine and microbiology, and his co-authors report that H. pylori infection may...

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...

Researchers report that Helicobacter pylori, the only bacterium known to survive in the harsh environment of the human stomach, directly activates an enzyme in host cells that has been associated with several types of cancer, including gastric cancer. Chronic infection with H. pylori is a well-documented risk factor for several forms of gastric cancer, but researchers have not yet determined the mechanisms by which specific bacterial factors contribute to cancer development. Nearly one-half...

The gastric cardiac adenocarcinoma (GCA) is a very rare disease. In recent decades, however, the incidence of the GCA has increased dramatically in many Western countries. An increasing trend in GCA is also observed in municipal regions but not in rural regions of China. Another striking feature is the strong male predominance among patients with GCA. Some of the reasons above are still unclear and require further epidemiological investigations. A research article published on November 21,...

Research team uncovers how the bacterium that causes ulcers travels through the sticky gels of stomach mucus Mucus is more than gross--it's a critical barrier against disease, trapping many of the germs that want to invade your body. A wet mesh of proteins, antiseptic enzymes and salts, mucus is what keeps all but a few microbes from wreaking havoc on many of our most exposed tissues. Helicobacter pylori is one of the few. The tiny, corkscrew-shaped microbe bores through the mucus that lines...

Since the isolation and culture of Helicobacter pylori (H. pylori) in 1983, this bacterium has become accepted as an important human pathogen for the development of gastritis, peptic ulcer, and gastric cancer. Cyclooxgenase-2 (COX-2) is a prostaglandin-synthesizing enzyme. Elevated expression of COX-2 is observed in a wide variety of human malignancies, including gastric cancer. Long-term high dose COX-2 inhibitors can inhibit gastric carcinogenesis in animal models, but the possible...

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...

  • In the phrase to out-herod Herod, to be more violent than Herod (as represented in the old mystery plays); hence, to exceed in any excess of evil.
Herod refers to 'Herod the Great,' a Roman client king and 'a madman who murdered his own family and a great many rabbis.' According to the OED, the term is 'chiefly with allusion to Shakespeare's use' in Hamlet.
