| gene products, rev | Trans-acting nuclear proteins whose functional expression are required for HIV viral replication. Specifically, the rev gene products are required for processing and translation of the HIV gag and env mRNAs, and thus rev regulates the expression of the viral structural proteins. Rev can also regulate viral regulatory proteins. A cis-acting antirepression sequence (car) in env, also known as the rev-responsive element (rre), is responsive to the rev gene product. Rev is short for regulator of virion. (12 Dec 1998) |

| genes, rev | DNA sequences that form the coding region for a protein that regulates the expression of the viral structural and regulatory proteins in human immunodeficiency virus (HIV). Rev is short for regulator of virion. (12 Dec 1998) |
| rev | <molecular biology> A regulatory protein produced by HIV within infected cells. Rev helps transport HIV RNA sequences (messenger RNA) out from the nucleus into the cells cytoplasm, where it directs construction of proteins for new virus particles. (11 Jan 1998) |
| china | A republic in east and central asia, known also as the people's republic of china. It is an ancient country, with a civilization existing as early as 3000 b.c. Until 1912 it was known as the chinese empire. It was one of the four great powers in world war II. By 1950 the communist regime had gained control. China became a member of the united nations in 1971. The name may be derived from the qin or ts'in dynasty (221-206 b.c.) or the sanskrit name cina or the central province of shaanxi or shensi (its capitalis shian). (12 Dec 1998) |
| China syndrome | <radiobiology> American jargon/slang for a nuclear fission meltdown accident (see meltdown) in which the molten nuclear core heats and melts the ground beneath it, thus sinking into the earth, and heading towards China (which is roughly on the opposite side of the globe). (09 Oct 1997) |
| Cochin China diarrhoea | An obsolete term for tropical sprue. (05 Mar 2000) |
| pseudo-china | <botany> The false china root, a plant of the genus Smilax (S. Pseudo-china), found in America. Origin: Pseudo- + china. Source: Websters Dictionary (01 Mar 1998) |
| bacteria-free stage of bacterial endocarditis | Endocarditis described prior to the antibiotic era and presumably due to spontaneous healing of the bacterial vegetations. (05 Mar 2000) |
| carbon dioxide-free water | Purified water that has been boiled vigorously for 5 minutes or more. (05 Mar 2000) |
| radical, free | In biochemistry, it is a group of atoms bonded together into an entity that is extremely reactive and shortlived. (a free radical is not a political extremist on parole.) (12 Dec 1998) |
| germ-free animal | An animal which has no microorganisms whatsoever living in or on it. An animal which was born and raised in an isolated environment with no microorganisms in it, such as within a germ-free isolator. (09 Oct 1997) |
| germ-free isolator | A chamber which has absolutely no microorganisms whatsoever living in it, where a germ-free animal can be born and raised. An artificial barrier surrounding a living facility for germ-free animals, which keeps out all microorganisms. (09 Oct 1997) |
| germ-free life | Animals not contaminated by or associated with any foreign organisms. (12 Dec 1998) |
| carrier-free | A substance in which a radioactive or other tagged atom is found in every molecule; the highest possible specific activity. (05 Mar 2000) |
| gibbs free energy | The total amount of energy which is either used up or released during a chemical reaction. Gibbs free energy (delta G) = (delta H) - t (delta s): where (delta H) is the change in enthalpy, calculated by adding up the amount of energy released or used up to break or form chemical bonds during the reaction, t is the temperature at which the reaction took place, and (delta S) is the change in entropy, or amount of disorder, that occurs in the molecules involved during the reaction.
