| biological hazard potential | <radiobiology> Measure of the hazard posed by a given quantity of radioactive material in which the variation in biological effects of the various elements are accounted for. See: integrated biological hazard potential. (21 Mar 1998) |
|---|---|
| biological immunotherapy | <immunology> Treatment of disease by stimulating the bodys own immune system. This is a type of therapy currently being researched as a treatment for cancer. (16 Dec 1997) |
| biological magnification | <biology, zoology> The process by which toxins such as pesticides build up in each successive link in the food chain. For instance, a given population of beetles may have very low levels of a fat-soluble pesticide, but the pesticide will build to much greater levels in the fat of a bird that eats those beetles, and the pesticide will reach greater levels still in a human or panther that eats the beetle-eating birds. (21 Mar 1998) |
| biological markers | Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, environmental exposure and its effects, disease diagnosis, metabolic processes, substance abuse, pregnancy, cell line development, epidemiologic studies, etc. (12 Dec 1998) |
| biological monitoring | This is the periodic examination of biological specimens for the purposes of monitoring their exposure to or the effects of potentially toxic chemicals to the environment. This is normally done by analysing the amounts of the toxic substances or their metabolites present in body tissues and fluids. The term is also used to mean assessment of the biological status of populations and communities of organisms at risk, in order to protect them and to gain an early warning of possible hazards to human health. (09 Oct 1997) |
| biological oceanography | <study> The study of marine plants and animals and the way they interact with the marine environments. Similar to the study of marine biology. (21 Mar 1998) |
| biological oxidation | Decomposition of organic materials by microorganisms. (05 Dec 1998) |
| biological phenomena | Biological functions and activities at the organic and molecular levels in humans, animals, microorganisms, and plants. For biochemical and metabolic processes, biochemical phenomena is available. (12 Dec 1998) |
| biological products | Complex pharmaceutical substances, preparations, or agents of organic origin, usually obtained by biological methods or assay, that depend for their action on the processes affecting immunity. They are used especially in diagnosis and treatment of disease (as vaccines or pollen extracts). Biological products are differentiated from biological factors in that the latter are compounds with biological or physiological activity made by living organisms. (12 Dec 1998) |
| biological psychiatry | An interdisciplinary science concerned with studies of the biological bases of behaviour - biochemical, genetic, physiological, and neurological - and applying these to the understanding and treatment of mental illness. (12 Dec 1998) |
| biological response modifier | <pharmacology, oncology> A substance used in adjuvant therapy that takes advantage of the bodys own natural defense mechanisms to inhibit the growth of a tumour. (16 Dec 1997) |
| biological response modifiers | Substances that stimulate the body's response to infection and disease. The body naturally produces small amounts of these substances. Scientists can produce some of them in the laboratory in large amounts and use them in cancer treatment. Also called BRMs. (12 Dec 1998) |
| biological sampling | Denotes sampling that can be taken without jeopardy to the whole organism (e.g., for haematological or biochemical study). Because of the complexity of biological samples it is usually supposed that the source of the sample is thoroughly mixed and hence representative; this assumption is often not true e.g., in genetic studies in mosaic patients. (05 Mar 2000) |
| biological sciences | All of the divisions of the natural sciences dealing with the various aspects of the phenomena of life and vital processes. The concept includes anatomy and physiology, biochemistry and biophysics, and the biology of animals, plants, and microorganisms. It should be differentiated from biology, one of its subdivisions, concerned specifically with the origin and life processes of living organisms. (12 Dec 1998) |
| biological specificity | <biology, zoology> The specific, orderly patterns of development and metabolism which define and characterise an individual and its species. (21 Mar 1998) |

| biological half-life |
The term which is used for the time required for the amount of a particular substance in a biological system to be reduced to one half of its value by biological processes when the rate of removal is approximately exponential. Substances with a long biological half-life will tend to accumulate in the body and are, therefore, particularly to be avoided. Substances with a short biological half-life may accumulate if some becomes tightly bound, even if most is cleared from the body rapidly. ...
