Company Profile:
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.
Type of endocytosis in which soluble materials are taken up by the cell and incorporated into vesicles for digestion.
Industry:Biology; Chemistry
Unicellular organism, characterized by the absence of a membrane-enclosed nucleus. Note: Prokaryotes include bacteria, blue-green algae and mycoplasmas.
Industry:Biology; Chemistry
Upper-bound excess lifetime cancer risk estimated to result from continuous exposure to an agent at a concentration of 1 μg L-1 in water, or 1 μg m-3 in air. Note: The interpretation of unit risk is as follows: if unit risk = 1.5 x 10-6 μg L-1, 1.5 excess tumors are expected to develop per 1 000 000 or 106 people if exposed daily for a lifetime to 1 μg of the chemical in 1 litre of drinking water.
Industry:Biology; Chemistry
Usually fibrosis of the lungs that develops owing to (prolonged) inhalation of inorganic or organic dusts. Note: Cause-specific types of pneumoconiosis are: # anthracosis: from coal dust. # asbestosis: from asbestos dust. # byssinosis: from cotton dust. # siderosis: from iron dust. # silicosis: from silica dust. # stannosis: from tin dust.
Industry:Biology; Chemistry
Value for the acceptable daily intake proposed for guidance when data are sufficient to conclude that use of the substance is safe over the relatively short period of time required to generate and evaluate further safety data, but are insufficient to conclude that use of the substance is safe over a lifetime. Note: A higher-than-normal safety factor is used when establishing a temporary ADI and an expiration date is established by which time appropriate data to resolve the safety issue should be available.
Industry:Biology; Chemistry
Value obtained by dividing the rate in an exposed population by the rate in an unexposed population.
Industry:Biology; Chemistry
Value, in inverse concentration or dose units, derived from the slope of a dose-response curve; in practice, limited to carcinogenic effects with the curve assumed to be linear at low concentrations or doses. Note: The product of the slope factor and the exposure is taken to reflect the probability of producing the related effect.
Industry:Biology; Chemistry
Vascular reaction of the skin marked by the transient appearance of smooth, slightly elevated patches (wheals, hives) that are redder or paler than the surrounding skin and often attended by severe itching.
Industry:Biology; Chemistry
Volume of plasma passing through the kidneys in unit time.
Industry:Biology; Chemistry
Water purification by natural biological and physico-chemical processes.
