| 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. Manner; gait. Origin: Icel. Gata; akin to SW. Gata street, lane, Dan. Gade, Goth. Gatwo, G. Gasse. Cf. Gate a door, Gait. 1. A large door or passageway in the wall of a city, of an inclosed field or place, or of a grand edifice, etc.; also, the movable structure of timber, metal, etc, by which the passage can be closed. 2. An opening for passage in any inclosing wall, fence, or barrier; or the suspended framework which closes or opens a passage. Also, figuratively, a means or way of entrance or of exit. "Knowest thou the way to Dover? Both stile and gate, horse way and footpath." (Shak) "Opening a gate for a long war." (Knolles) 3. A door, valve, or other device, for stopping the passage of water through a dam, lock, pipe, etc. 4. The places which command the entrances or access; hence, place of vantage; power; might. "The gates of hell shall not prevail against it." (Matt. Xvi. 18) 5. In a lock tumbler, the opening for the stump of the bolt to pass through or into. 6. The channel or opening through which metal is poured into the mold; the ingate. The waste piece of metal cast in the opening; a sprue or sullage piece. Alternative forms: geat and git] Gate chamber, a recess in the side wall of a canal lock, which receives the opened gate. Gate channel. See Gate. Gate hook, the hook-formed piece of a gate hinge. Gate money, entrance money for admission to an inclosure. Gate tender, one in charge of a gate, as at a railroad crossing. Gate valva, a stop valve for a pipe, having a sliding gate which affords a straight passageway when open. <anatomy> Gate vein, to enter a college inclosure after the hour to which a student has been restricted. 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) |
| radiation inactivation | The technique of inactivating proteins in freeze dried (lyophilised) preparations using high energy particles (e.g. Electrons). One high energy particle can apparently inactivate all of the components of a multisubunit polypeptide, the method is therefore used to determine the molecular weight of functional oligomers. (18 Nov 1997) |
| X inactivation | <cell biology> The inactivation of one or other of each pair of X chromosomes to form the Barr body in female mammalian somatic cells. Thus tissues whose original zygote carried heterozygous X borne genes should have individual cells expressing one or other but not both of the X borne gene products. The inactivation is thought to occur early in development and leads to mosaicism of expression of such genes in the body. See: Lyon hypothesis. (18 Nov 1997) |
| inactivation | <neurology, physiology> For example of voltage gated sodium channels: process by which sodium channels that have been activated or opened by depolarisation subsequently close during the depolarisation. Distinguished from activation by its slower kinetics. (18 Nov 1997) |
| insertional inactivation | The inactivation of a gene due to the insertion of exogenous genetic material into that gene. (14 Nov 1997) |
| enzyme inactivation | The disappearance of an enzyme's activity during in vitro conditions, such as during a lab preparation of the enzyme, where the enzyme is exposed to conditions not normally found within its environment inside a living cell (like different pH, excess or too little salt, temperature changes, etc.) (09 Oct 1997) |
