| RAEB-T | Refractory Anemia with Excess Blasts in Transformation |
|---|---|
| ATZ | atypical transformation zone |
| ELECTZ | electrosurgical loop excision of the cervical transformation zone |
| HLT | heart-lung transplantation; human lipotropin; human lymphocyte transformation |
| LETS | large external transformation-sensitive [protein] |
| transformation efficiency | The number of bacterial cells that uptake and express plasmid DNA divided by the mass of plasmid used (in transformants/microgram). (09 Oct 1997) |
|---|---|
| transformation, genetic | The unidirectional transfer and incorporation of foreign DNA by prokaryotic or eukaryotic cells and the subsequent recombination of part or all of that DNA into the cell's genome. (glossary of genetics: classical and molecular, 5th ed) (12 Dec 1998) |
| transformation zone | Zone on the cervix at which squamous epithelium and columnar epithelium meet; changes location in response to a woman's hormonal status. (05 Mar 2000) |
| Lobry de Bruyn-van Ekenstein transformation | The conversion of glucose to fructose and mannose in dilute alkali by enolization adjacent to the carbonyl group to form an enediol, a reaction analogous to certain biochemical transformations. (05 Mar 2000) |
| logit transformation | A method of linearizing dose-response curves for radioimmunoassay techniques; i.e., Logit B (bound)/Bo(initial binding) = Log (B/Bo/1-B/Bo). (05 Mar 2000) |
| lymphocyte transformation | <haematology> The change in morphology and behaviour of lymphocytes exposed to a mitogen or to an antigen to which they have been primed. The result is the production of lymphoblasts, cells that are actively engaged in protein synthesis and that divide to form effector populations. Should not be confused with transformation of the type associated with oncogenic viruses and activation is therefore perhaps a better term. (18 Nov 1997) |
| calcific nodular aortic stenosis | Most common type of aortic stenosis, occurring usually in elderly men, in which the cusps contain calcified fibrous nodules on both surfaces; the causes include rheumatic fever, atherosclerosis, age-related degeneration, and congenitally bicuspid aortic valve. (05 Mar 2000) |
| panniculitis, nodular nonsuppurative | A form of panniculitis characterised by recurrent episodes of fever accompanied by the eruption of single or multiple erythematous subcutaneous nodules on the lower extremities. They normally resolve, but tend to leave depressions in the skin. The condition is most often seen in women, alone or in association with other disorders. (12 Dec 1998) |
| goiter, nodular | An enlarged thyroid gland containing circumscribed nodules within its substance. (12 Dec 1998) |
| Salzmann's nodular corneal degeneration | Large and prominent nodules of a solid, opaque material that stands out from the surface of the cornea; occurs occasionally in persons previously affected by phlyctenular keratitis. (05 Mar 2000) |
| nodular | Bumpy. (12 Dec 1998) |
| nodular amyloidosis | A localised form of amyloidosis in which amyloid occurs as masses or nodules beneath the skin or mucous membranes, e.g., in the larynx. Synonym: amyloid tumour, focal amyloidosis. (05 Mar 2000) |
| nodular arteriosclerosis | Atheromas occurring in the arterial intima as discrete tumours. (05 Mar 2000) |
| nodular body | In fungi, a compact, roughly spherical or squarish structure formed by coiling and twisting of the end of a hypha; considered to be abortive growths toward sexual reproduction. (05 Mar 2000) |
| nodular disease | Oesophagostomiasis in herbivores and primates, characterised by nodules in the wall of the large intestine, caecum, and occasionally, the ileum; the nodules are filled with caseous material and result from host response to encystment of the larvae of Oesophagostomum species.
