| V-ONC | viral oncogene |
|---|---|
| VP | physiological volume; vapor pressure; variegate porphyria; vascular permeability; vasopressin; velop... |
| VPP | vacuolar proton pump; viral porcine pneumonia |
| VRI | viral respiratory infection; virtual reality imaging |
| VRNA | viral ribonucleic acid |
| viral oncogene | <molecular biology> A viral gene that contributes to cancer development in vertebrate hosts. (09 Oct 1997) |
|---|---|
| viral pericarditis | Pericarditis due to a viral infection. (05 Mar 2000) |
| viral physiology | Biological processes and activities of viruses. (12 Dec 1998) |
| viral pneumonia | <radiology> Common agents: RSV, parainfluenza, adenovirus, influenza (12 Dec 1998) |
| viral probe | A nucleic acid fragment, labelled by a radioisotope, biotin, etc., that is complementary to a sequence in another nucleic acid (fragment) and that will, by hydrogen binding to the latter, locate or identify it and be detected; a diagnostic technique based on the fact that every species of microbe possesses some unique nucleic acid sequences which differentiate it from all others, and thus can be used as identifying markers or "fingerprints." (05 Mar 2000) |
| viral proteins | Proteins found in any species of virus. (12 Dec 1998) |
| viral regulatory proteins | Proteins which regulate the rate of transcription of viral structural genes. (12 Dec 1998) |
| viral strand | See: replicative form. (05 Mar 2000) |
| viral structural proteins | Viral proteins that do not regulate transcription. They are coded by viral structural genes and include nucleocapsid core proteins (gag proteins), enzymes (pol proteins), and membrane components (env proteins). Transcription of viral structural genes is regulated by viral regulatory proteins. (12 Dec 1998) |
| viral tail proteins | Proteins found in the tail sections of DNA and RNA viruses. It is believed that these proteins play a role in directing chain folding and assembly of polypeptide chains. (12 Dec 1998) |
| viral therapy | The use of genetically altered virus particles for delivering genes to specific sites for the purpose of therapy. (05 Mar 2000) |
| viral transformation | <oncology, virology> Malignant transformation of an animal cell in culture, induced by a virus. (18 Nov 1997) |
| viral vaccines | Suspensions of attenuated or killed viruses administered for the prevention or treatment of infectious viral disease. (12 Dec 1998) |
| viral vector | <molecular biology> Viral DNA that has been modified to serve as a vector for recombinant DNA. (11 Nov 1997) |
| viral wart | A keratotic papilloma of the epidermis which occurs most frequently in young persons as a result of localised infection by human papilloma virus, usually types 2 and 4; the lesions are of variable duration, eventually undergoing spontaneous regression, and are both exophytic and endophytic, with hyperkeratosis, parakeratosis, hypergranulosis, koilocytosis, and papillomatosis. Synonym: common wart, infectious warts, verruca simplex, viral wart. (05 Mar 2000) |
