| RPIPP | reverse phase ion-pair partition |
| reverse Eck fistula | Side-to-side anastomosis of the portal vein with the inferior vena cava and ligation of the latter above the anastomosis but below the hepatic veins; the blood from the lower part of the body is thus directed through the hepatic circulation. (05 Mar 2000) |

| reverse electron transport | <chemistry> The energy-dependent movement of electrons against the thermodynamic gradient to form a strong reductant from a weaker electron donor. (11 Jan 1998) |
| reverse genetics | The technique of determining a gene's function by first sequencing it, then mutating it and then trying to identify the nature of the change in the phenotype. (18 Nov 1997) |
| reverse Kingsley splint | A winged maxillary splint used to apply traction to reduce maxillary fractures as well as immobilise them by having the wings attached to a head appliance by elastics. Synonym: reverse Kingsley splint. (05 Mar 2000) |
| reverse mutation | <molecular biology> A mutation that causes a mutant gene to revert to its original wild-type base sequence. Compare: forward mutation. (09 Oct 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) |
