GastritisCagA: Helicobacter pylori virulence factor CagA (cytotoxin-associated gene A) is a 120–145kDa protein encoded on the 40kb cag pathogenicity island (PAI). H.Gastric mucosal barrier: The gastric mucosal barrier is the property of the stomach that allows it to contain acid.Gastrin: Gastrin is a peptide hormone that stimulates secretion of gastric acid (HCl) by the parietal cells of the stomach and aids in gastric motility. It is released by G cells in the pyloric antrum of the stomach, duodenum, and the pancreas.Intestinal metaplasia: 200px|right|thumb|Intestinal metaplasia (top middle of image) of the gastric antrum and [[stomach cancer|adenocarcinoma of the stomach (left/centre of image). H&E stain.Stomach diseaseAchlorhydriaGastric erosion: Gastric erosion occurs when the mucous membrane lining the stomach becomes inflamed. Some drugs, as tablets, can irritate this mucous membrane, especially drugs taken for arthritis and muscular disorders, steroids, and aspirin.Little gastrin IJohn Lykoudis: John Lykoudis (1910 in Missolonghi – 1980) was a general practitioner in Greece who treated patients suffering from peptic ulcer disease with antibiotics long before it was commonly recognized that bacteria were a dominant cause for the disease.Reactive gastropathy: In gastroenterology, reactive gastropathy, also chemical gastropathy, is an abnormality in the stomach caused by chemicals, e.g.Gastric acid: Gastric acid is a digestive fluid, formed in the stomach. It is composed of hydrochloric acid (HCl) .Non-communicable disease: Non-communicable disease (NCD) is a medical condition or disease that is non-infectious or non-transmissible. NCDs can refer to chronic diseases which last for long periods of time and progress slowly.DuodenitisElisha K. Green: Elisha K. Green (1839–1917) was an entrepreneur in Los Angeles, California, who "made a fortune out of windmills" and served for six years on the Common Council, the governing body of that city.Nepean HospitalHelicobacter pullorum: Helicobacter pullorum is a bacterium in the Helicobacteraceae family, Campylobacterales order. It was isolated from the liver, duodenum, and caecum of broiler and layer chickens, and from humans with gastroenteritis.Brain biopsyDodecameric protein: A dodecameric protein has a quaternary structure consisting of 12 protein subunits in a complex. Dodecameric complexes can have a number of subunit 'topologies', but typically only a few of the theoretically possible subunit arrangements are observed in protein structures.Oxyhyperglycemia: Oxyhyperglycemia is a special type of Impaired glucose tolerance characterized by a rapid and transient hyperglycemia (ie rise in blood glucose) spike after an oral intake of glucose, the peak of this spike being high enough to cause transient, symptom free glycosuria (i.e.Epithelial dysplasia: Epithelial dysplasia, a term becoming increasingly referred to as intraepithelial neoplasia, is the sum of various disturbances of epithelial proliferation and differentiation as seen microscopically. Individual cellular features of dysplasia are called epithelial atypia.Campylobacter concisus: Campylobacter concisus is a Gram-negative, spiral, and microaerophilic bacteria. Motile, with either unipolar or bipolar flagella, the organisms have a characteristic spiral/corkscrew appearance and are oxidase-positive.Testicular atrophy: Testicular atrophy is a medical condition in which the male reproductive organs (the testes, which in humans are located in the scrotum) diminish in size and may be accompanied by loss of function. This does not refer to temporary changes, such as those brought on by cold.Feline spongiform encephalopathy: Feline spongiform encephalopathy is a disease that affects the brains of felines. It is caused by proteins called prions.Endoscopy unit: An endoscopy unit refers to a dedicated area where medical procedures are performed with endoscopes, which are cameras used to visualize structures within the body, such as the digestive tract and genitourinary system. Endoscopy units may be located within a hospital, incorporated within other medical care centres, or may be stand-alone in nature.Secretagogue: A secretagogue is a substance that causes another substance to be secreted. One example is gastrin,secretagogue at eMedicine Dictionary which stimulates the H/K ATPase in the parietal cells (increased gastric acid production by the stomach).AmoxicillinAutoimmune diseaseOmeprazoleRødgrød: Rødgrød (Danish, ), rote Grütze (German), or Rode Grütt (Low German), meaning "red groats", is a sweet fruit dish from Denmark and Germany. The name of the dish in Danish features many of the elements that make Danish pronunciation difficult for non-native speakers, so 'rødgrød med fløde' (red groats with cream) is thus a commonly used shibboleth.GastroenterostomyPernicious anemiaSodium bismuthateFerric uptake regulator family: In molecular biology, the ferric uptake regulator (FUR) family of proteins includes metal ion uptake regulator proteins. These are responsible for controlling the intracellular concentration of iron in many bacteria.ThymectomyCampylobacteriosisEsophagitisAntacidDiffuse infiltrative lymphocytosis syndrome: Diffuse infiltrative lymphocytosis syndrome occurs in HIV positive patients with low CD4 counts.Functional gastrointestinal disorder: Functional gastrointestinal disorders (FGID) include a number of separate idiopathic disorders which affect different parts of the gastrointestinal tract and involve visceral hypersensitivity and impaired gastrointestinal motility. Heightened mast cell activation is a common factor among all FGIDs that contributes to visceral hypersensitivity as well as epithelial, neuromuscular, and motility dysfunction.Stretta procedure: Stretta is a minimally invasive endoscopic procedure for the treatment of gastroesophageal reflux disease (GERD). A catheter is used to deliver radiofrequency energy to the lower esophageal sphincter, muscle and gastric cardia.
