Concentration of a substance that causes a defined inhibition of a given system.
Note: IC50 is the median concentration that causes 50% inhibition.
Industry:Biology; Chemistry
Concentration of a substance that causes a defined magnitude of response in a given system.
Note: EC50 is the median concentration that causes 50 % of maximal response.
Industry:Biology; Chemistry
Condition marked by softening of the bones (due to impaired mineralization, with excess accumulation of osteoid), with pain, tenderness, muscular weakness, anorexia and loss of weight, resulting from deficiency of vitamin D and calcium.
Industry:Biology; Chemistry
Condition resulting from the ingestion of an excess of one or more vitamins.
Industry:Biology; Chemistry
Consequence that can be measured on a graded scale of intensity or severity and its magnitude related directly to the dose or concentration of the substance producing it.
Industry:Biology; Chemistry
Continuous or repeated measurement of agents in the environment to evaluate environmental exposure and possible damage by comparison with appropriate reference values based on knowledge of the probable relationship between ambient exposure and resultant adverse effects.
Industry:Biology; Chemistry
Conversion of the genetic information encoded in DNA into a final gene product (either a protein or any of the different types of RNA).
Note: Because changes in RNA synthesis are often estimated by measuring mRNA levels, the term “gene expression” is often misleadingly used as synonymous with transcription. The term “gene expression” includes transcription, processing, and splicing of mRNA, as well as translation, and post-translational modification of the protein product.
Industry:Biology; Chemistry
Critical publications of IPCS containing reviews of methodologies and existing knowledge - expressed, if possible, in quantitative terms - of selected substances (or groups of substances) on identifiable, immediate, and long-term effects on human health and welfare.
Industry:Biology; Chemistry
Cyclical process involving intestinal re-absorption of a substance that has been excreted through the bile, followed by transfer back to the liver, making it available for biliary excretion again.
Industry:Biology; Chemistry
Damage or adverse effect to a population, species, individual organism, organ, tissue or cell.
Industry:Biology; Chemistry
