| 11-cis-retinal | The isomer of retinaldehyde that can combine with opsin to form rhodopsin; it is formed from 11-trans-retinal by retinal isomerase. Synonym: neoretinal b. (05 Mar 2000) |
|---|---|
| aseptic necrosis | <orthopaedics, pathology> Condition in which poor blood supply to an area of bone leads to bone death. Also called avascular necrosis and osteonecrosis. (12 Dec 1998) |
| avascular necrosis | <radiology> Aetiology (PLASTIC RAGS): P pancreatitis, L lupus, A alcohol, S steroids, T trauma, I idiopathic, infection, C caisson disease, collagen vascular disease, R radiation, rheumatoid arthritis, A amyloid, G Gaucher disease, S sickle cell disease findings: sclerosis, crescent sign, collapse (e.g., of femoral head) see also: staging (12 Dec 1998) |
| avascular necrosis staging | <radiology> Stage CT/X-ray bone scan I - cold/hot spot II sclerotic focus with osteopenic ring III crescent sign (subchondral lucency) IV articular collapse flattening of femoral head sensitivity 86% 78% specificity 79% 75% see also: avascular necrosis (AVN) (12 Dec 1998) |
| bridging hepatic necrosis | Area of liver necrosis which bridges adjacent portal areas and central veins; subsequent post-necrotic collapse and fibrosis is likely to result in cirrhosis. (05 Mar 2000) |
| p60 tumour necrosis factor receptor-associated kinase | <enzyme> Interacts with and causes phosphorylation of the cytoplasmic domain of the tnf receptor Registry number: EC 2.7.10.- Synonym: p60 tnf receptor-associated kinase, p60-trak (26 Jun 1999) |
| papillary necrosis | <radiology> Mnemonic: POST CARD, P pyelonephritis, O obstruction, S sickle cell disease, T TB, C cirrhosis (EtOH), A analgesics (phenacetin and aspirin), R renal vein thrombosis, D diabetes (12 Dec 1998) |
| receptors, tumour necrosis factor | Cell surface receptors that bind tumour necrosis factor and trigger changes which influence the behaviour of cells. The two recognised tumour necrosis factor receptors are designated alpha and beta receptors. Both receptors bind both alpha and beta tumour necrosis factors with high affinity, and both are members of the nerve growth factor receptor family. (12 Dec 1998) |
| caseous necrosis | Caseation necrosis, necrosis characteristic of certain inflammations (e.g., tuberculosis, histoplasmosis), which represents necrosis with loss of separate structures of the various cellular and histologic elements; affected tissue manifests the friable, crumbly consistency and dull, opaque quality observed in cheese. Synonym: caseous degeneration. (05 Mar 2000) |
| globus pallidus necrosis | <radiology> Carbon monoxide poisoning, barbiturate intoxication, cyanide poisoning, hydrogen sulfide poisoning, hypoglycaemia, hypoxia, hypotension, Leigh disease, Wilson disease CT: bilateral, symmetric low density in globus pallidus Cf: methanol intoxication leading to putamenal haemorrhagic necrosis (changes seen more laterally) (12 Dec 1998) |
| renal papillary necrosis | <nephrology> Necrosis of renal papillae, occurring in acute pyelonephritis, especially in diabetics, or in analgesic nephropathy; renal failure may result. Synonym: necrotizing papillitis. (05 Mar 2000) |
| central necrosis | Necrosis involving the deeper or inner portions of a tissue, or an organ or its units. (05 Mar 2000) |
| cerebrocortical necrosis | A noninfectious disease of ruminants characterised by a tissue-thiamine deficiency and by amaurosis and strabismus, followed by recumbency, opisthotonos, and convulsions. Synonym: cerebrocortical necrosis. (05 Mar 2000) |
| coagulation necrosis | A type of necrosis in which the affected cells or tissue are converted into a dry, dull, fairly homogeneous eosinophilic mass without nuclear staining, as a result of the coagulation of protein as occurs in an infarct; microscopically, the necrotic process involves chiefly the cells, and remnants of histologic elements (e.g., elastin, collagen, muscle fibres) may be recognizable, as well as "ghosts" of cells and portions of cell membranes; may be caused by heat, ischemia, and other agents that destroy tissue, including enzymes that would continue to alter the devitalised cellular substance. (05 Mar 2000) |
| colliquative necrosis | An obsolete term for liquefactive necrosis. (05 Mar 2000) |
