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.
Measure of the amount of oxygen, divided by the volume of the system, required to oxidize the organic (and inorganic) matter in wastewater using a chemically oxidizing agent. In practice, it is usually expressed in milligrams O2 per litre.
Industry:Biology; Chemistry
Condition in which there is a reduction in the number of red blood cells or amount of hemoglobin per unit volume of blood below the reference interval for a similar individual of the species under consideration, often causing pallor and fatigue.
Industry:Biology; Chemistry
State in which an individual reacts with allergic effects caused by the reaction of antigen-specific T-lymphocytes following exposure to a certain substance (allergen) after having been exposed previously to the same substance or chemical group.
Industry:Biology; Chemistry
Biomarker that relates exposure to a xenobiotic to the levels of the substance or its metabolite, or of the product of an interaction between the substance and some target molecule or cell that can be measured in a compartment within an organism.

Industry:Biology; Chemistry
Restoration of the molecular structure of DNA after it has been damaged by a chemical or physical agent: this may involve direct DNA damage reversal, base excision repair, nucleotide excision repair, mismatch repair, or double-strand break repair
Industry:Biology; Chemistry
Scientific study involving research, education, prevention and treatment of diseases caused by substances such as drugs and toxins.
Note: Often refers specifically to the application of toxicological principles to the treatment of human poisoning.
Industry:Biology; Chemistry
Specialized layers of extra-cellular matrix (basal laminae) that separate epithelial tissue from underlying connective tissue: cancer cells must break through the basement membrane in order to migrate to other parts of the body and form metastases.
Industry:Biology; Chemistry
Orange-yellow pigment, a breakdown product of heme-containing proteins (hemoglobin, myoglobin, cytochromes), which circulates in the blood plasma bound to albumin or as water soluble glucuronide conjugates, and is excreted in the bile by the liver.
Industry:Biology; Chemistry
Product of the concentration co of a component in an output system and the volume flow rate of the output system divided by the concentration ci of this component in the input system.
Note: The term ‘mean volume rate’ is recommended for this quantity.
