| growth hormone inhibiting hormone | <protein> Gastrointestinal and hypothalmic peptide hormone (two forms: 14 and 28 residues), found in gastric mucosa, pancreatic islets, nerves of the gastrointestinal tract, in posterior pituitary and in the central nervous system. Inhibits gastric secretion and motility: in hypothalamus/pituitary inhibits somatotropin release. (18 Nov 1997) |
|---|---|
| mullerian inhibiting substance | A 535 amino acid glycoprotein secreted by the Sertoli cells of the testis. It is related to inhibin. Synonym: mullerian inhibiting factor. (05 Mar 2000) |
| prolactin-inhibiting hormone | A substance of hypothalamic origin capable of inhibiting the synthesis and release of prolactin. Synonym: prolactin-inhibiting factor, prolactin-inhibiting hormone. Origin: prolactin + G. Stasis, standing still, + -in (05 Mar 2000) |
| inhibiting antibody | An "incomplete" form of antibody that may coat antigen, but which according to the "lattice theory" does not have a second receptor for attachment to another molecule of antigen; in the case of Rh+ erythrocytes, such an anti-Rh antibody may coat the cells but not cause them to agglutinate in saline; however, agglutination does occur when such coated cells are suspended in serum or other protein media, such as albumin, therefore called serum agglutinin. Synonym: incomplete antibody, inhibiting antibody. (05 Mar 2000) |
| carpal tunnel release | <orthopaedics, procedure> An orthopaedic surgical procedure which relieves the pressure exerted on the median nerve within the carpal tunnel in the wrist. This surgery may be performed conventionally via a small incision or using a fibreoptic scope (endoscopic carpal tunnel repair). (08 Jan 1998) |
| Release | <chemical> Abscission agent for loosening citrus fruit before harvesting Synonym: 5-chloro-3-methyl-4-nitro-1h-pyrazole (26 Jun 1999) |
| release phenomenon | The increased tonus and hyperirritability of muscle-stretch reflexes which occur following damage of the upper portions of the extrapyramidal system. (05 Mar 2000) |
| ryanodine receptor calcium release channel | Protein complexes that mediate the release of calcium from the sarcoplasmic reticulum in both skeletal and cardiac muscle cells by forming tetrametric complexes. These complexes each then act as a calcium channel. There are three isoforms of the ryr: ryr1, ryr2, and ryr3. Ryr1 is specifically expressed in skeletal muscles and ryr2 in cardiac muscles. Ryr3 is yet another isoform found in non-muscle cells such as neuronal cells. (12 Dec 1998) |
| control release suture | Eyeless suture with thread attached to needle such that the two separate when tension is applied to the thread. (05 Mar 2000) |
| histamine release | The secretion of histamine from mast cell and basophil granules by exocytosis. This can be initiated by a number of factors, all of which involve binding of IgE, cross-linked by antigen, to the mast cell or basophil's fc receptors. Once released, histamine binds to a number of different target cell receptors and exerts a wide variety of effects. (12 Dec 1998) |
| deliberate release | Generally refers to putting a genetically manipulated organism into field trials. (14 Nov 1997) |
| sustained release tablet | A drug product formulation that provides the required dosage initially and then maintains or repeats it at desired intervals. Synonym: prolonged action tablet, repeat action tablet. (05 Mar 2000) |
| accelerator factor | <chemical> Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor v accomplishes this by forming a complex with factor xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor v leads to owren's disease. Chemical name: Blood-coagulation factor V (12 Dec 1998) |
| acetate replacement factor | <biochemistry> 1,2 dithiolane 3 valeric acid. Regarded as a coenzyme in the oxoglutarate dehydrogenase complex of the citric acid cycle. Involved generally in oxidative decarboxylations of _ keto acids. A growth factor for some organisms. (18 Nov 1997) |
| adrenal weight factor | A postulated substance of adenohypophysial origin responsible for maintenance of the weight of the adrenal cortex. (05 Mar 2000) |
