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.
Health risk remaining after risk reduction actions are implemented.
Industry:Biology; Chemistry
Binding of a substance, or its metabolites from a phase I reaction, with endogenous molecules (conjugation), making more water-soluble derivatives that may be excreted in the urine or bile.
Note: Phase II reactions include glucuronidation, sulfation, acetylation, amino acid (e.g., glycine) and glutathione conjugation.
Industry:Biology; Chemistry
Biological change resulting from an environmental alteration lasting about 10 % of the lifetime of the test organism.
Note: In practice with experimental animals, such an effect is usually identified as resulting from multiple or continuous exposures occurring over 3 months (90 days). Sometimes a subchronic effect is distinguished from a subacute effect on the basis of its lasting for a much longer time.
Industry:Biology; Chemistry
Biological change with detectable symptoms following exposure to an agent known to cause disease either before symptoms of the disease occur or when they are absent.
Industry:Biology; Chemistry
Blocking transmission of impulses from the adrenergic (sympathetic) postganglionic fibers to effector organs or tissues.
Industry:Biology; Chemistry
Boundary value defined so that a stated fraction of the reference values is less than or exceeds that boundary value with a stated probability.
Industry:Biology; Chemistry
Cell which has become genetically altered spontaneously or by incorporation of foreign DNA to produce a cell with an extended lifetime in culture.
Industry:Biology; Chemistry
Change from normal structure or function, induced by a substance or other agent(s), that returns to normal status or within normal limits after cessation of exposure.
Industry:Biology; Chemistry
Chemical grouping which is known to be associated with a particular type of toxic effect, e.g. mutagenicity.
Industry:Biology; Chemistry
Chemical reaction (or reaction sequence) in which one or more new elements of chirality are formed in a substrate molecule and which produces the stereoisomeric (enantiomeric or diastereoisomeric) products in unequal amounts.
Note: Traditionally called asymmetric synthesis.
