| simple beam | In dentistry, a straight beam that has only two supports, one at either end. (05 Mar 2000) |
|---|---|
| neutral axis of straight beam | The axis perpendicular to the plane of loading of a beam at stresses within the proportional limit; it lies at the gravity axis of the cross-section of the beam. (05 Mar 2000) |
| neutral beam injection | <radiobiology> This is one of the fundamental plasma heating methods. A particle accelerator is used to create fast ion beams (the particle energies are on the order of 100 keV), the ion beam is then passed through a neutral gas region, where the ions neutralise via charge-exchange reactions with the neutral gas. The neutralised beam is then injected into a magnetically confined plasma. The neutral atoms are unaffected (not confined) by the magnetic field, but ionize as they penetrate into the plasma. The high-energy ions then transfer some of their energy to the plasma particles in repeated collisions, and heat the plasma. (09 Oct 1997) |
| electron beam | <microscopy> A stream of electrons in an electron optical system. (05 Aug 1998) |
| acupuncture therapy | Treatment of disease by inserting needles along specific pathways or meridians. The placement varies with the disease being treated. Heat or moxibustion and acupressure may be used in conjunction. (12 Dec 1998) |
| adjuvant therapy | <oncology, pharmacology> Treatment that is added to increase the effectiveness of a primary treatment. In cancer, adjuvant treatment usually refers to chemotherapy, hormonal therapy or radiation therapy after surgery to increase the likelihood of killing all cancer cells. (14 May 1997) |
| alternative therapy | A term given to nonconventional therapy usually given by persons who do not have a medical qualification. (16 Dec 1997) |
| analytic therapy | Short term for psychoanalytic therapy. (05 Mar 2000) |
| Antibody Directed Enzyme Prodrug Therapy | <pharmacology> A method for targeting a drug to a specific tissue, in which the targeting agent and the drug are administered separately. The drug is designed to be inactive (a prodrug) until it is converted by an enzyme, which is the targeting agent. The enzyme is coupled to an antibody that directs it to the tissue of interest. When the enzyme arrives at the tissue, the prodrug is activated only at that site, sparing other tissues from potentially toxic side effects. Acronym: ADEPT (14 Nov 1997) |
| anticoagulant therapy | The use of anticoagulant drugs to reduce or prevent intravascular or intracardiac clotting. (05 Mar 2000) |
| antisense therapy | Use of antisense DNA for the inhibition of translation of a specific gene product for therapeutic purposes. (05 Mar 2000) |
| art therapy | The use of art as an adjunctive therapy in the treatment of neurological, mental, or behavioural disorders. (12 Dec 1998) |
| autoserum therapy | Therapy with serum obtained from the patient's own blood. (05 Mar 2000) |
| aversion therapy | <psychology> A form of behaviour therapy that pairs an unpleasant stimulus with undesirable behaviour(s) so that the patient learns to avoid the latter. See: aversive training. (05 Mar 2000) |
| aversive therapy | <psychology> A treatment that suppresses undesirable behaviour by simultaneously exposing the subject to unpleasant consequences. (12 Dec 1998) |
