| NTZ | normal transformation zone |
| PBLT | peripheral blood lymphocyte transformation |
| PNT | partial nodular transformation; patient |
| 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) |
| acute viral conjunctivitis | An epidemic inflammation of the conjunctiva marked by follicles, especially in the lower fornix; may be caused by adenoviruses, herpesvirus, and Newcastle disease virus. (05 Mar 2000) |
| antibodies, viral | Immunoglobulins produced as a response to viral antigens; includes all classes of immunoglobulins elicited by all viral components. (12 Dec 1998) |
| antigens, viral | Substances elaborated by viruses that have antigenic activity. (12 Dec 1998) |
| antigens, viral, tumour | Those proteins recognised by antibodies from serum of animals bearing tumours induced by viruses; these proteins are presumably coded for by the nucleic acids of the same viruses that caused the neoplastic transformation. (12 Dec 1998) |
| avian viral arthritis virus | A virus of the genus Reovirus, family Reoviridae, causing tenosynovitis and arthritis in chickens. (05 Mar 2000) |
| bronchiolitis, viral | An acute inflammatory disease of the upper respiratory tract, caused by paramyxoviruses, occurring primarily in infants and young children; the viruses most commonly implicated are parainfluenza type 3 and respiratory syncytial virus. (12 Dec 1998) |
| gene expression regulation, viral | Any of the processes by which cytoplasmic factors influence the differential control of gene action in viruses. (12 Dec 1998) |
| genes, structural, viral | DNA or RNA sequences that code for RNA and for the proteins required for the enzymatic and structural function of viral cells. (12 Dec 1998) |
| genes, viral | The hereditary material of viruses, consisting in all DNA and some RNA viruses of a single molecule of nucleic acid, and in some RNA viruses of several separate pieces of RNA. (12 Dec 1998) |
