The National Library of Medicine (NLM), on the campus of the National Institutes of Health in Bethesda, Maryland, is the world's largest medical library. The Library collects materials and provides information and research services in all areas of biomedicine and health care.
1. Chemical species produced in living organisms by covalently linking two chemical moieties from different sources.
2. Material produced by attaching two or more substances together, e.g. a conjugate of an antibody with a fluorochrome, or an enzyme.
Industry:Biology; Chemistry
1. In pharmacology, a substance added to a drug to speed or increase the action of the main component.
2. In immunology, a substance (such as aluminum hydroxide) or an organism (such as killed mycobacterium) which increases the response to an antigen.
Industry:Biology; Chemistry
Type of lymphocyte which synthesizes and secretes antibodies in response to the presence of a foreign substance or one identified by it as foreign. The protective effect can be mediated to a certain extent by the antibody alone (contrast T lymphocyte).

Industry:Biology; Chemistry
1. Process, or processes, of chemical modification which make a toxic molecule less toxic.
2. Treatment of patients suffering from poisoning in such a way as to promote physiological processes which reduce the probability or severity of adverse effects.

Industry:Biology; Chemistry
1. Probability of a common harmful effect associated with concurrent exposure by all relevant pathways and routes of exposure to a group of substances that share a common chemical mechanism of toxicity.
2. Total probability of a harmful effect over time.
Industry:Biology; Chemistry
Stage of development of an organism, e.g., organogenesis in the fetus, that is of particular importance in the life cycle if the normal full development of some anatomical, physiological, metabolic, or psychological structure or function is to be attained.
Industry:Biology; Chemistry
Progressive increase in the amount of a substance in an organism or part of an organism which occurs because the rate of intake exceeds the organism's ability to remove the substance from the body.
Note: Bio-accumulation often correlates with lipophilicity.
Industry:Biology; Chemistry
Continuous or repeated measurement of agents in the environment to evaluate ambient exposure and health risk by comparison with appropriate reference values based on knowledge of the probable relationship between exposure and resultant adverse health effects.
