| 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) |
| gate | 1. A way; a path; a road; a street (as in Highgate). "I was going to be an honest man; but the devil has this very day flung first a lawyer, and then a woman, in my gate." (Sir W. Scott) 2.

To stand in the gate, or gates, to occupy places or advantage, power, or defense. Origin: OE. Et, eat, giat, gate, door, AS. Geat, gat, gate, door; akin to OS, D, & Icel. Gat opening, hole, and perh. To E. Gate a way, gait, and get, v. Cf. Gate a way in the wall, 3d Get. Source: Websters Dictionary (01 Mar 1998) |
| gate-control hypothesis | A theory to explain the mechanism of pain; small fibre afferent stimuli, particularly pain, entering the substantia gelatinosa can be modulated by large fibre afferent stimuli and descending spinal pathways so that their transmission to ascending spinal pathways is blocked (gated). Synonym: gate-control hypothesis. (05 Mar 2000) |

| flap gate | <ecology, equipment> A device which allows water to flow in only one direction through a culvert, can be used to allow water to drain out of a wetland during low tide while preventing water from entering the wetland during high tide. (09 Oct 1997) |
| antirheumatic agents, gold | Gold salts that are effective in the therapy of rheumatoid arthritis. These compounds usually do not have analgesic activity. Since these compounds are poorly absorbed from the intestinal tract, they are usually given intramuscularly. (12 Dec 1998) |

| gold | 1. <chemistry> A metallic element, constituting the most precious metal used as a common commercial medium of exchange. It has a characteristic yellow colour, is one of the heaviest substances known (specific gravity 19.32), is soft, and very malleable and ductile. It is quite unalterable by heat, moisture, and most corrosive agents, and therefore well suited for its use in coin and jewelry. Symbol Au (Aurum). Atomic weight 196.7. Native gold contains usually eight to ten per cent of silver, but often much more. As the amount of silver increases, the colour becomes whiter and the specific gravity lower. Gold is very widely disseminated, as in the sands of many rivers, but in very small quantity. It usually occurs in quartz veins (gold quartz), in slate and metamorphic rocks, or in sand and alluvial soil, resulting from the disintegration of such rocks. It also occurs associated with other metallic substances, as in auriferous pyrites, and is combined with tellurium in the minerals petzite, calaverite, sylvanite, etc. Pure gold is too soft for ordinary use, and is hardened by alloying with silver and copper, the latter giving a characteristic reddish tinge. [See Carat] Gold also finds use in gold foil, in the pigment purple of Cassius, and in the chloride, which is used as a toning agent in photography. 2. Money; riches; wealth. "For me, the gold of France did not seduce." (Shak) 3. A yellow colour, like that of the metal; as, a flower tipped with gold. 4. Figuratively, something precious or pure; as, hearts of gold. Age of gold. See Golden age, under Golden. Dutch gold, Fool's gold, Gold dust, etc. See Dutch, Dust, etc. Gold amalgam, a mineral, found in Columbia and California, composed of gold and mercury. Gold beater, one whose occupation is to beat gold into gold leaf.

Gold diggings, the places, or region, where gold is found by digging in sand and gravel from which it is separated by washing. Gold end, a fragment of broken gold or jewelry. Gold-end man. A buyer of old gold or jewelry. A goldsmith's apprentice. An itinerant jeweler. "I know him not: he looks like a gold-end man." . Gold fever, a popular mania for gold hunting. Gold field, a region in which are deposits of gold. Gold finder. One who finds gold. One who empties privies. Gold flower, a composite plant with dry and persistent yellow radiating involucral scales, the Helichrysum Stoechas of Southern Europe. There are many South African species of the same genus. Gold foil, thin sheets of gold, as used by dentists and others. See Gold leaf. <botany> Gold knobs or knoppes A small evergreen plant (Coptis trifolia), so called from its fibrous yellow roots. It is common in marshy places in the United States. Gold tissue, a tissue fabric interwoven with gold thread.

Gold washings, places where gold found in gravel is separated from lighter material by washing. Gold worm, a glowworm. Jeweler's gold, an alloy containing three parts of gold to one of copper. Mosaic gold. See Mosaic. Origin: AS. Gold; akin to D. Goud, OS. & G. Gold, Icel. Gull, Sw. & Dan. Guld, Goth. Gulp, Russ. & OSlav. Zlato; prob. Akin to E. Yellow. See Yellow, and cf. Gild.
