| reverse passive haemagglutination | If antibodies are bonded to the surface of red blood cells haemagglutination will occur if the appropriate bi or multivalent antigen is added in soluble or microparticulate form. Used as a test for for example Hepatitis B virus in the serum. (18 Nov 1997) |
|---|---|
| reverse pulmonary oedema pattern | <radiology> Loeffler pneumonia, chronic eosinophilic pneumonia (12 Dec 1998) |
| reverse transcriptase | <enzyme> RNA directed DNA polymerase. Enzyme first discovered in retroviruses, that can construct double stranded DNA molecules from the single stranded RNA templates of their genomes. Reverse transcription now appears also to be involved in movement of certain mobile genetic elements, such as the Ty plasmid in yeast, in the replication of other viruses such as Hepatitis B and possibly in the generation of mammalian pseudogenes. (18 Nov 1997) |
| reverse transcriptase inhibitors | Inhibitors of reverse transcriptase (RNA-directed DNA polymerase), an enzyme that synthesises DNA on an RNA template. (12 Dec 1998) |
| reverse transcriptase md | <molecular biology> A viral enzyme that constructs DNA from an RNA template, which is an essential step in the life-cycle of a retrovirus such as HIV (09 Oct 1997) |
| reverse transcriptase PCR | A technique used to amplify RNA targets. The specimen containing the target RNA (e.g., HIV-1 RNA, Hepatitis C Virus RNA) is subjected to reverse transcription to make complementary DNA (cDNA), which is then, in turn, amplified by PCR. Acronym: RT-PCR (05 Mar 2000) |
| reverse transcription | <molecular biology> The process of copying information found in RNA into DNA. (09 Oct 1997) |
| reverse transcriptons | An enzyme that converts RNA to DNA. Some viruses have only RNA as their primary genetic material. By converting their RNA genes to DNA with this enzyme, the host cell is 'tricked' into creating new copies of the virus. Useful in genetic engineering to make DNA from mRNA. (14 Nov 1997) |
| reverse Trendelenburg position | Supine position without flexing or extending, in which the head is higher than the feet. (05 Mar 2000) |
| HIV-1 reverse transcriptase | <enzyme> HIV-1 enzyme responsible for the synthesis of DNA from genomic RNA of the virus. It is encoded by the pol gene of HIV-1. Registry number: EC 2.7.7.- (12 Dec 1998) |
| HIV-2 reverse transcriptase | <enzyme> Responsible for synthesis of double-stranded DNA from the genomic RNA of the virus; has rnase h and DNA-dependent DNA polymerase activities; was indexed as reverse transcriptase (87-91) Registry number: EC 2.7.7.- (26 Jun 1999) |
| DNA reverse gyrase | <enzyme> A topoisomerase II subclass which introduces positive superhelical turns into DNA Registry number: EC 3.1.- Synonym: reverse gyrase (26 Jun 1999) |
| triiodothyronine, reverse | <chemical> 0-(4-hydroxy-3,5-diiodophenyl)-3-iodo-l-tyrosine. A metabolite of thyroxine formed by the peripheral degradation of thyroxine as a result of the tyrosyl or inner ring 5-deiodination. In systemic disease states or in neonates, levels of triiodothyronine are low and those of reverse triiodothyronine are elevated. Reverse t3 is therefore useful as a diagnostic aid and in the treatment of foetal and infantile hypothyroidism. Chemical name: L-Tyrosine, O-(4-hydroxy-3,5-diiodophenyl)-3-iodo- (12 Dec 1998) |
