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.
Surface on a target where a substance, e.g., a pesticide is present. With mammals, examples of outer exposure surfaces include the exterior of an eyeball, the skin surface and a conceptual surface over the nose and open mouth. Examples of inner exposure surfaces include the gastrointestinal tract, the respiratory tract and the urinary tract lining.
Industry:Biology; Chemistry
Technical and administrative procedures and specifications applied for the monitoring, reduction or elimination of emissions from a source or exposure to a target.
Industry:Biology; Chemistry
Technique used to decrease the expression of a particular gene in a cell or living organism in order to define its function.
Industry:Biology; Chemistry
Technique used to express a exogenous gene or to overexpress an endogenous gene in a living organism in order to define its function.
Note: In mammalian toxicology, this technique is most readily applied to the mouse.
Industry:Biology; Chemistry
Technique used to inactivate a particular gene in a living organism in order to define its function.
Note: In mammalian toxicology, this technique is most readily applied to the mouse.
Industry:Biology; Chemistry
Term used to describe the responses of (effects on) an individual to (of) an agent when they are qualitatively those expected, but quantitatively increased.
Industry:Biology; Chemistry
Test for allergic sensitivity in which a suspected allergen is applied to the skin on a small surgical pad.
Note: Patch tests may be used to detect exposure to pesticides.
Industry:Biology; Chemistry
Theoretical volume of a body compartment throughout which a substance is calculated to be distributed.
Industry:Biology; Chemistry
Therapeutic introduction of a fluid other than blood, as a (usually saline) solution, into a vein.
Industry:Biology; Chemistry
This expression is applicable to a substance for which the available information is not sufficient to establish its safety, or when the specifications for identity and purity are not adequate, or when the available data show that the substance is hazardous and should not be used.
Note: The basis for the use of the expression should be determined before action is taken; in the first two cases above, not being able to allocate an ADI does not mean that the substance is unsafe.
