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.Norman Barrett: Norman Rupert Barrett (1903–1979) was an Australian-born British thoracic surgeon who is primarily remembered for describing Barrett's oesophagus.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.Gastric mucosal barrier: The gastric mucosal barrier is the property of the stomach that allows it to contain acid.GastritisGoblet cell: A goblet cell is a glandular, modified simple columnar epithelial cell whose function is to secrete gel-forming mucins, the major components of mucus. The goblet cells mainly use the merocrine method of secretion, secreting vesicles into a duct, but may use apocrine methods, budding off their secretions, when under stress.Acute esophageal necrosisMyelofibrosisStomach diseaseCagA: Helicobacter pylori virulence factor CagA (cytotoxin-associated gene A) is a 120–145kDa protein encoded on the 40kb cag pathogenicity island (PAI). H.Angle of His: The angle of His is the acute angle created between the cardia at the entrance to the stomach, and the esophagus. It forms a valve, preventing reflux of duodenal bile, enzymes and stomach acid from entering the esophagus, where they can cause inflammation.DuodenitisProgressive osseous heteroplasia: Progressive osseous heteroplasia is a cutaneous condition characterized by cutaneous or subcutaneous ossification.Brain biopsyAdenocarcinoma of the lung: Adenocarcinoma of the lung (pulmonary adenocarcinoma) is a common histological form of lung cancer that contains certain distinct malignant tissue architectural, cytological, or molecular features, including gland and/or duct formation and/or production of significant amounts of mucus.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.Gastric chief cell: A gastric chief cell (or peptic cell, or gastric zymogenic cell) is a type of cell in the stomach that releases pepsinogen and gastric lipase and is the cell responsible for secretion of chymosin in ruminants. The cell stains basophilic upon H&E staining due to the large proportion of rough endoplasmic reticulum in its cytoplasm.Stratified squamous epithelium: A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Only one layer is in contact with the basement membrane; the other layers adhere to one another to maintain structural integrity.Mucus: In vertebrates, mucus ( ; adjectival form: "mucous") is a slippery secretion produced by, and covering, mucous membranes. Mucous fluid is typically produced from cells found in mucous glands.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.Reactive gastropathy: In gastroenterology, reactive gastropathy, also chemical gastropathy, is an abnormality in the stomach caused by chemicals, e.g.Gastric 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.Hyperplasia: Hyperplasia (from ancient Greek ὑπέρ huper, "over" + πλάσις plasis, "formation"), or hypergenesis, is an increase in the amount of organic tissue that results from cell proliferation. It may lead to the gross enlargement of an organ and the term is sometimes confused with benign neoplasia or benign tumor.Apocrine sweat glandKeratin 6A: Keratin 6A is one of the 27 different type II keratins expressed in humans. Keratin 6A was the first type II keratin sequence determined.Bronchus: A bronchus, also known as a main or primary bronchus, is a passage of airway in the respiratory tract that conducts air into the lungs. There is a right bronchus and a left bronchus and these bronchi branch into smaller secondary and tertiary bronchi which branch into smaller tubes, known as bronchioles.
