A team of researchers from Boston University, Harvard Medical School and Massachusetts Institute of Technology recently made a discovery that changes a long held paradigm about how bacteria move through soft gels. They showed that the bacterium that causes human stomach ulcers uses a clever biochemical strategy to alter the physical properties of its environment, allowing it to move and survive and further colonize its host.The Proceedings of the National Academy of Sciences reports the...

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...

About half of the world's population carries Helicobacter pylori, mainly in the stomach. Most infected individuals never experience any symptoms, but around 10% get peptic ulcers and around 1% develop stomach cancer. 'Carriers were often infected as children and if not treated with antibiotics, the bacterium remains in the body for life. The immune system alone is unable to eliminate the bacterium, and now we understand better why', says biologist Bert Kindlund, the author of the thesis.The...

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...

 Current research suggests that levels of gastrin play a key role in the development of Helicobacter-induced stomach cancer. The related report by Takaishi et al, "Gastrin is an essential cofactor for Helicobacter-associated gastric corpus carcinogenesis in C57BL/6 mice," appears in the July 2009 issue of The American Journal of Pathology.More than 50% of the world's population is infected with Helicobacter pylori, which causes chronic inflammation of the stomach lining and is strongly...

GES or pacing has been under investigation as a potential therapy for gastrointestinal motility disorders. Conventionally, GES is performed using a single pair of electrodes or single-channel GES. However, few studies have investigated the effects of two-channel GES with trains of pulses on gastric motility, such as gastric slow waves and gastric emptying. A research article to be published in May 21, 2009 in the World Journal of Gastroenterology addresses this question. The research team...

Mayo Clinic researchers have shown that very low doses of inhaled carbon monoxide in diabetic mice reverses the condition known as gastroparesis or delayed stomach emptying, a common and painful complication for many diabetic patients. The findings will be presented on June 1 at Digestive Disease Week in Chicago. "This is a significant finding, as it shows that loss of the enzyme that makes carbon monoxide is the actor in this process and that it provides us with a clear approach toward a...

First human trial demonstrates feasibility and safety of MAG techniqueA prospective clinical trial from researchers in Japan shows magnetic-anchor-guided endoscopic submucosal dissection for large early gastric cancer to be a feasible and safe method in humans. Endoscopic submucosal dissection (ESD) is useful in the en bloc removal (in a single large piece) of large gastric lesions because it reduces the risk of a local recurrence caused by removing the lesions piecemeal (in multiple small...

Two cell proteins that relax the gut and help accommodate a big meal have been identified by UCL (University College London) scientists. The proteins could offer a future drug target against weight gain, by preventing the stomach from expanding.In a paper published in this month's issue of the Journal of Pharmacology and Experimental Therapeutics, Dr Brian King and Dr Andrea Townsend-Nicholson explored the molecular basis of relaxations of the gut. In the study, the authors identified two...

Crocodiles are ferocious creatures that will eat snakes, buffalo, cattle and even people. New research explains crocodiles' spectacular method of digesting large meals that lets them eat 23 percent of their body weight at once, bones and all. If people could gorge like crocodiles, a 130-pound woman could down a 30-pound hamburger in one sitting. The secret behind this champion eating is a heart valve that crocs control neurologically, which lets blood bypass the lungs and flow...

The stomach is the hollow organ that helps along digestion after mastication (chewing). It is the next step after the esophagus and before the small intestines. Formation and Orientation The stomach is composed of four parts. The cardia is the first part of the stomach in the digestive tract. It is the part of the stomach that allows the food to empty from the esophagus. The most northern part of the stomach is the Fundus. This section is the part that creates the curved part of the...

Gastric Chief Cell
2012-07-01 18:59:43

The Gastric Chief Cell (peptic cell or gastric zymogenic cell) is a cell found in the stomach that releases pepsinogen, gastric lipase and Chymosin (an enzyme that clots milk). Pepsinogen is only released when the cell is stimulated by a number of factors, including cholinergic activity and increased acidity in the stomach. The gastric chief cell works in conjunction with the parietal cell, which releases gastric acid, converting pepsinogen into pepsin. The term “chief cell” is...

The Magnificent Star (Luidia magnifica), is a species of starfish in the family Luidiidae. It is found only in the Pacific Ocean on sandy areas of the seabed surrounding Hawaii and the Philippines at a depth of 60 to 440 feet. This starfish can grow quite large, with one specimen found on the Pearl and Hermes Atoll, Hawaii, measuring 33 inches in diameter. It usually has ten long, tapering arms with pointed tips, but will sometimes have 11 arms. One or more of these arms may regenerate...
