Other mucus-secreting cells are the mucous neck cells in the necks of the gastric glands. [2]: 257 Surface mucous cells have large quantities of mucin granules in their apical (top) surface and project short microvilli into the lumen of the stomach. [2]: 257 Mucins are large glycoproteins that give the mucus its gel-like properties. [3]
The first cells of all of the glands are mucus-secreting foveolar cells that line the gastric pits. The mucus produced here is less acidic than that produced by the mucous neck cells. Fundic glands found in the fundus and also in the body have another two cell types–gastric chief cells and parietal cells (oxyntic cells).
Pseudomyxoma peritonei (PMP) is a clinical condition caused by cancerous cells (mucinous adenocarcinoma) that produce abundant mucin or gelatinous ascites. [1] The tumors cause fibrosis of tissues and impede digestion or organ function, and if left untreated, the tumors and mucin they produce will fill the abdominal cavity.
Stomach cancer, also known as gastric cancer, is a malignant tumor of the stomach. It's a cancer that develops from the lining of the stomach . [ 10 ] Most cases of stomach cancers are gastric carcinomas , which can be divided into a number of subtypes, including gastric adenocarcinomas . [ 2 ]
The sodium-iodide symporter (SIP) is expressed in all the surface mucous cells (at the basolateral membrane) but not in the mucous neck cells. SIP mediates the transport of iodide from the bloodstream and secretes it into the gastric lumen where it is taken up in the gastric juice. Its role is not known but it has been shown to be absent in ...
Owing to the causal relationship between H. pylori infection and gastric MALT lymphoma, identification of the infection is imperative. Histological examination of GI biopsies yields a sensitivity of 95% with five biopsies, [7] but these should be from sites uninvolved by lymphoma and the identification of the organism may be compromised by areas of extensive intestinal metaplasia.
What the symptoms are: Mild symptoms of listeriosis include fever, muscle aches, nausea, vomiting and diarrhea, while symptoms for the more severe form of listeriosis include headache, stiff neck ...
Squamous cell cancer, upper oesophagus. Gastrointestinal cancer refers to malignant conditions of the gastrointestinal tract (GI tract) and accessory organs of digestion, including the esophagus, stomach, biliary system, pancreas, small intestine, large intestine, rectum and anus. The symptoms relate to the organ affected and can include ...
