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.
Life threatening type 1 hypersensitivity allergic reaction (see allergy) occurring in a person or animal exposed to an antigen or hapten to which they have previously been sensitized.
Note: Consequences of the reaction may include angio-edema, vascular collapse, shock, and respiratory distress.
Industry:Biology; Chemistry
Symptoms or signs occurring in sensitized individuals following exposure to a previously encountered substance (allergen) which would otherwise not cause such symptoms or signs in non-sensitized individuals. The most common forms of allergy are rhinitis, urticaria, asthma, and contact dermatitis.
Industry:Biology; Chemistry
Pathological condition resulting when an organism produces antibodies or specific cells which bind to constituents of its own tissues (autoantigens) and cause tissue injury: examples of such disease may include rheumatoid arthritis, myasthenia gravis, systemic lupus erythematosus, and scleroderma.
Industry:Biology; Chemistry
Material which enhances or maintains the cleaning efficiency of a surfactant, in a detergent, principally by inactivating water hardness; complex phosphates (especially sodium tripolyphosphate, i.e. pentasodium triphosphate), sodium carbonate, and sodium silicate are the builders most commonly used.
Industry:Biology; Chemistry
Pathological condition characterized by grey-bluish or black pigmentation of tissues (such as skin, retina, mucous membranes, internal organs) caused by the accumulation of metallic silver, due to reduction of a silver compound which has entered the organism during (prolonged) administration or exposure.

Industry:Biology; Chemistry
Sensations that arise when chemical compounds activate receptor mechanisms for other effectors, such as light, pain, pressure, and heat, in the eye, skin, nose, mouth and throat; e.g., the burning feeling from chili pepper, the cooling from the menthol in mouthwash, and the stinging feeling of carbonation.
Industry:Biology; Chemistry
Estimate by JECFA of the amount of a food additive, expressed on a body weight basis, that can be ingested daily over a lifetime without appreciable health risk.
Note 1: For calculation of ADI, a standard body mass of 60 kg is used.
Note 2: Tolerable Daily Intake (TDI) is the analogous term used for contaminants.
Industry:Biology; Chemistry
Sample observations for which the complete distribution is not known: for example, a cohort study in which some persons cannot be followed to the predetermined end of the study (“right-censored data”) or environmental assay data in which some results are less than the sample detection limit (“left-censored data”).
Industry:Biology; Chemistry
Constituent of chromosomes which stores the hereditary information of an organism in the form of a sequence of purine and pyrimidine bases: this information relates to the synthesis of proteins and hence it is a determinant of all physical and functional activities of the cell, and consequently of the whole organism.
