|---|---|---|---|
| 설명 | 일반적으로, 생체나 생체 물질이 그 기능을 활발하게 나타내게 되는 것, 예를 들면 ① 촉매 등에서, 그 표면 상태의 변화나, 다른 물질의 첨가 등에 의하여, 그 기능이 현저하게 높아지는 것. ② 효소전구체의 활성화로서 효소작용을 가지지 않는 효소 전구체가 활성있는 효소로 변화는 것. 또 황화수소나 시안화수소산 등으로 파파인이 활성화되는 경우도 있다. |

| 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) |
| activation | <radiobiology> Activation occurs when a particle interacts with an atomic nucleus, shifting the nucleus into an unstable state, and causing it to become radioactive. In fusion research, where deuterium-tritium is a common fuel mixture, the neutron released when (D + T) combine to form (4He + n) can activate the reactor structure. In this case the 4He is inert, the neutron sticks to another nucleus, and the neutron + nucleus reaction creates an actvation product. Sometimes called radioactivation. See: activation product, activation analysis. (09 Oct 1997) |
| activation analysis | <radiobiology> Method for identifying and measuring chemical elements in a sample of material. Sample is first made radioactive by bombardment with neutrons, charged particles, or gamma rays. Newly formed radioactive atoms in the sample then give off characteristic radiations (such as gamma rays) that tell what kinds of atoms are present, and how many. (09 Oct 1997) |
| activation energy | <chemistry> The amount of energy (expressed in joules) that is needed to convert all the molecules in one mole of a reacting substance from a ground state to the transition state. (06 May 1997) |
| activation product | <radiobiology> The unstable nucleus formed when activation occurs. (See activation above.) (09 Oct 1997) |
| amino acid activation | The first step of protein synthesis, whereby an amino acid reacts with adenosine triphosphate in the presence of aminoacyl RNA synthetase to produce an amino acid adenylate, which provides the energy necessary for the attachment of the amino acid to a specific transfer RNA molecule. (12 Dec 1998) |
| macrophage activation | The process of altering the morphology and functional activity of macrophages so that they become avidly phagocytic. It is initiated by lymphokines, such as the macrophage activation factor (maf) and the macrophage migration-inhibitory factor (mmif), immune complexes, c3b, and various peptides, polysaccharides, and immunologic adjuvants. (12 Dec 1998) |
| gene activation | The process of activation of a gene so that it is expressed at a particular time. This process is crucial in growth and development. (05 Mar 2000) |
| Gibbs energy of activation | The Gibbs energy that must be added to that already possessed by a molecule or molecules in order to initiate a reaction. (05 Mar 2000) |
| virus activation | The mechanism by which latent viruses, such as genetically transmitted tumour viruses or prophages of lysogenic bacteria, are induced to replicate and are released as infectious viruses. It may be effected by various endogenous and exogenous stimuli, including B-cell lipopolysaccharides, glucocorticoid hormones, halogenated pyrimidines, ionizing radiation, ultraviolet light, and superinfecting viruses. (12 Dec 1998) |
| cis activation | <molecular biology> Activation of a gene by an activator located on the same chromosome i.e. Not by a diffusible product. (18 Nov 1997) |
| complement activation | The sequential activation of serum components c1 through c9, initiated by an erythrocyte-antibody complex or by microbial polysaccharides and properdin, and producing an inflammatory response. (12 Dec 1998) |
