| inhibitory junction potential | Hyperpolarization of smooth muscle produced by stimulation of inhibitory nerves. (05 Mar 2000) |
|---|---|
| inhibitory-motor | <physiology> A term applied to certain nerve centers which govern or restrain subsidiary centers, from which motor impressions issue. Source: Websters Dictionary (01 Mar 1998) |
| inhibitory nerve | <anatomy, nerve> A nerve conveying impulses that diminish functional activity in a part. (05 Mar 2000) |
| inhibitory postsynaptic potential | The change in potential produced in the membrane of the next neuron when an impulse which has an inhibitory influence arrives at the synapse; it is a local change in the direction of hyperpolarization; the frequency of discharge of a given neuron is determined by the extent to which impulses that lead to excitatory postsynaptic potential's predominate over those that cause inhibitory postsynaptic potential's. (05 Mar 2000) |
| inhibitory synapse | A synapse in which an action potential in the presynaptic cell reduces the probability of an action potential occurring in the postsynaptic cell. The most common inhibitory neurotransmitter is GABA, this opens channels in the postsynaptic cell which tend to stabilise its resting potential, thus rendering it less likely to fire. See: excitatory synapse, presynaptic inhibition, postsynaptic inhibition. (18 Nov 1997) |
| Leukaemia inhibitory factor | <growth factor> Polypeptide growth factor or cytokine with wide range of activities. Regulates growth and differentiation of primordial germ cells and embryonic stem cells but has effects on peripheral neurons, osteoblasts, adipocytes and various cells of the myeloid lineage. Given to adult animals induces weight loss, behavioural disorders and bone abnormalities. Many of the effects of LIF in vitro can be mimicked by IL-6, oncostatin M and ciliary neurotrophic factor, all of which interact indirectly with gp130, a shared tranducer subunit. (18 Nov 1997) |
| leukocyte migration-inhibitory factors | Protein factor(s) released by sensitised lymphocytes (and possibly other cells) that inhibit the movement of leukocytes, especially polymorphonuclear cells, away from their site of release. Assays for these factors are used as tests for cellular immunity. Two of the common assays are the leukocyte migration capillary tube technique (lmct) and the leukocyte migration agarose technique (lmat). (12 Dec 1998) |
| absorbed dose | The amount of energy absorbed per unit mass of irradiated material at the target site; in radiation therapy, the former unit for absorbed dose is the rad; the current (S.I.) unit is the gray. (05 Mar 2000) |
| air dose | The radiation dose, expressed in roentgens, delivered at a point in free air. Synonym: air dose. (05 Mar 2000) |
| bone marrow dose | The cumulative dose to the blood-forming organ from therapeutic or nuclear fallout irradiation; the presumed leukemogenic dose. (05 Mar 2000) |
| booster dose | A dose given at some time after an initial dose to enhance the effect, said usually of antigens for the production of antibodies. (05 Mar 2000) |
| breast dose in mammography | <radiology> 180 mrad / view -- mid-breast dose, guideline: less than 1 rad for 2-view exam (12 Dec 1998) |
| maintenance dose | In chemotherapy, systematic dosage at a level that maintains protection against exacerbation. (05 Mar 2000) |
| genetically significant dose | <physics, radiobiology> The genetically significant dose is that which, if received by every member of the population, would be expected to produce the same genetic injury to the population as do the actual doses received by the individuals irradiated. Thus, the genetically significant dose is the dose equivalent to the gonads weighted for the age and sex distribution in those members of the irradiated population expected to have offspring. The genetically significant dose is expressed in sieverts (or rem). Acronym: GSD (06 Aug 1998) |
| maximal dose | <pharmacology> The largest amount of a drug or physical procedure that an adult can take with safety. (05 Mar 2000) |
