| aids serodiagnosis | Immunologic tests for identification of HIV (HTLV-III/lav) antibodies. They include assays for HIV seropositivity and HIV seronegativity (elisa, immunofluorescence, immunoblot, etc.) that have been developed for screening persons carrying the viral antibody from patients with overt symptoms of aids or aids-related complex. (12 Dec 1998) |
|---|---|
| AIDS test | <investigation> A test which is performed on a standard venipuncture blood specimen which detects the presence of antibodies to HIV (virus). This test may not be positive for 3 to 6 months after infection with HIV. (27 Sep 1997) |
| aids vaccines | Vaccines or candidate vaccines containing inactivated HIV or some of its component antigens and designed to prevent aids. Some vaccines containing antigens are recombinantly produced. (12 Dec 1998) |
| audiovisual aids | Auditory and visual instructional materials. (12 Dec 1998) |
| communication aids for disabled | Equipment that provides mentally or physically disabled persons, who cannot speak effectively, with a means of communication. The aids include display boards, typewriters, cathode ray tubes, computers, and speech synthesisers. The output of such aids includes written words, artificial speech, language signs, morse code, and pictures. (12 Dec 1998) |
| hearing aids | Devices which amplify sound to help persons with hearing loss. (12 Dec 1998) |
| lymphoma, aids-related | B-cell lymphoid tumours that occur in association with aids. Patients often present with an advanced stage of disease and highly malignant subtypes including burkitt lymphoma, immunoblastic large-cell lymphoma, small non-cleaved-cell lymphoma and diffuse large-cell lymphoma. The tumours are often disseminated in unusual extranodal sites and chromosomal abnormalities are frequently present. It is likely that polyclonal B-cell lymphoproliferation in aids is a complex result of ebv infection, HIV antigenic stimulation, and T-cell-dependent HIV activation. (12 Dec 1998) |
| accumulation analysis | A technique in which an intermediate of a metabolic pathway accumulates due to selective inhibition of a particular step in that pathway or in a mutant that is deficient in a certain step. The intermediate is then isolated, analyzed, and identified. (05 Mar 2000) |
| 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) |
| actuarial analysis | The application of probability and statistical methods to calculate the risk of occurrence of any event, such as onset of illness, recurrent disease, hospitalization, disability, or death. It may include calculation of the anticipated money costs of such events and of the premiums necessary to provide for payment of such costs. (12 Dec 1998) |
| amino acid analysis | Determination and identification of amino acid content of a macromolecule, identification of a specific amino acid in macromolecules, often a mutated protein, identification and quantitation of amino acid content in blood plasma or urine; a key diagnostic aid. (05 Mar 2000) |
| analysis | <technique> The separation into component parts or elements, the act of determining the component parts of a substance. Origin: Gr. Lysis = dissolution (18 Nov 1997) |
| analysis of variance | A statistical technique that isolates and assesses the contributions of categorical independent variables to variation in the mean of a continuous dependent variable. (12 Dec 1998) |
| base sequence analysis | <molecular biology> A method, sometimes automated, for determining the base sequence. (09 Oct 1997) |
| bite analysis | A study of the relations of the occlusal surfaces of opposing teeth and their effect upon related structures. Synonym: bite analysis. (05 Mar 2000) |
