| clonal | Pertaining to a clone. (05 Mar 2000) |
|---|---|
| clonal aging | The deterioration in successive generations of a clone; thus paramecia and other simple forms, if allowed to reproduce asexually for a number of generations, invariably undergo deterioration, the characters of each group of descendants progressively departing from those of the original sexually produced ancestor. (05 Mar 2000) |
| clonal anergy | Functional inactivation of t- or B-lymphocytes rendering them incapable of eliciting an immune response to antigen. This occurs through different mechanisms in the two kinds of lymphocytes and can contribute to self tolerance. (12 Dec 1998) |
| clonal deletion | The removal of B-cell and T-cell varieties which recognise parts of the organisms body as targets of the immune system. This process naturally occurs early in the organisms development so that the organism will not be autoimmune (having an immune reaction against one's own body tissues) later in life. (09 Oct 1997) |
| clonal deletion theory | The elimination of certain T-cell populations in the thymus that have receptors for self-antigens. See: immunologic tolerance. (05 Mar 2000) |
| clonal selection | <cell biology> The process whereby one or more clones, i.e. Cells expressing a particular gene sequence are selected by naturally occurring processes from a mixed population. Generally the clonal selection is for general expansion by mitosis, particularly with reference to B lymphocytes where selection with subsequent expansion of clones occurs as a result of antigenic stimulation only of those lymphocytes bearing the appropriate receptors. (18 Nov 1997) |
| clonal selection theory | A theory which states that each lymphocyte has membrane bound immunoglobulin receptors specific for a particular antigen and once the receptor is engaged, proliferation of the cell occurs such that a clone of antibody producing cells (plasma cell) is produced. (05 Mar 2000) |
| membrane expansion theory | That adsorption of anaesthetics into membranes so alters membrane volume and/or configuration that membrane function is affected in such a way as to produce anaesthesia. (05 Mar 2000) |
| perceptual expansion | Development of an ability to recognise and interpret sensory stimuli through associations with past similar stimuli; perceptual expansion by relaxation of defenses is a goal of psychotherapy. (05 Mar 2000) |
| wax expansion | In dentistry, a method of expanding wax patterns to compensate for the shrinkage of gold during the casting process. (05 Mar 2000) |
| setting expansion | The dimensional increase that occurs concurrently with the hardening of various materials, such as plaster of Paris. (05 Mar 2000) |
| hygroscopic expansion | Expansion due to the absorption of moisture, in dental casting, the addition of water to the surface of the casting investment during setting to increase the size of the mold. (05 Mar 2000) |
| thermal expansion | <radiobiology> Characteristic property of most solids and liquids which causes their volume to increase when they are heated. Thermal expansion and contraction can cause structural problems in pulsed fusion devices. (09 Oct 1997) |
| tissue expansion | Process whereby tissue adjacent to a soft tissue defect is expanded by means of a subcutaneously implanted reservoir. The procedure is used in reconstructive surgery for injuries caused by trauma, burns, or ablative surgery. (12 Dec 1998) |
| expansion | 1. The act of expanding or spreading out; the condition of being expanded; dilation; enlargement. 2. That which is expanded; expanse; extend surface; as the expansion of a sheet or of a lake; the expansion was formed of metal. "The starred expansion of the skies." (Beattie) 3. Space thought which anything is expanded; also, pure space. "Lost in expansion, void and infinite." (Blackmore) 4. Enlargement or extension of business transaction; especially, increase of the circulation of bank notes. 5. <mathematics> The developed result of an indicated operation; as, the expansion of (a + b)^2 is a^2 + 2ab + b^2. 6. The operation of steam in a cylinder after its communication with the boiler has been cut off, by which it continues to exert pressure upon the moving piston. 7. <astronomy> The enlargement of the ship mathematically from a model or drawing to the full or building size, in the process of construction. Expansion is also used adjectively, as in expansion joint, expansion gear, etc. Expansion curve, a curve the coordinates of which show the relation between the pressure and volume of expanding gas or vapor; especially. A cut-off valve, to shut off steam from the cylinder before the end of each stroke. Origin: L. Expansio: cf. F. Expansion. Source: Websters Dictionary (01 Mar 1998) |
