Absorption further down the intestinal tract of a substance or substances that have been absorbed before and subsequently excreted into the intestinal tract, usually through the bile.
Industry:Biology; Chemistry
According to the US EPA's guidelines for Carcinogen Risk Assessment, “limited evidence” is a collection of facts and accepted scientific inferences that suggests that an agent may be causing an effect, but this suggestion is not strong enough to be considered established fact.
Industry:Biology; Chemistry
According to the US NIOSH, the maximum exposure concentration from which one could escape within thirty minutes without any escape-impairing symptoms or any irreversible health effects.
Industry:Biology; Chemistry
Acetoacetate, beta-hydroxybutyrate and acetone, produced from acetyl-CoA, mainly in the mitochondria of liver cells when carbohydrates are so scarce that energy must be obtained from breaking down fatty acids; beta-hydroxybutyrate is not itself a ketone but is called a ketone body because, like the other compounds, it is produced from ketones.
Industry:Biology; Chemistry
Act of drawing in of air, vapor or gas and any suspended particulates into the lung.
Industry:Biology; Chemistry
Actual physical, chemical, and social environment as described by objective measurements, such as noise levels in decibels and concentrations of air pollutants.
Industry:Biology; Chemistry
Acute or chronic skin inflammation with erythema, papules, vesicles, pustules, scales, crusts or scabs, alone or in combination, of varied etiology.
Industry:Biology; Chemistry
Acute toxicity test in which a substance is tested initially at a small number (3 or 4) predefined doses to identify which produces evident toxicity without lethality: the test may be repeated at one or more higher or lower defined discriminating doses to satisfy the criteria.
Industry:Biology; Chemistry
Acute toxicity test in which, if no ill-effects occur at a pre-selected maximum dose, no further testing at greater exposure levels is required.
Industry:Biology; Chemistry
