Latest Stomach Stories
Research team uncovers how the bacterium that causes ulcers travels through the sticky gels of stomach mucus.
Helicobacter pylori (H pylori) is a gram negative bacterium which infects about 50% of the world population. H pylori colonization causes a strong systemic immune response.
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.
About half of the worldâ€™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.
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
Current research suggests that levels of gastrin play a key role in the development of Helicobacter-induced stomach cancer.
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.
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.
A 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 pieces). ESD is a complicated procedure that requires a high level of...
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...
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...
