| turpentine poisoning | Poisoning from oil of turpentine; symptoms include haematuria, albuminuria, and coma; the urine may have an odour of violets. Synonym: terebinthinism. (05 Mar 2000) |
|---|---|
| zinc poisoning | <disease> Symptoms of zinc poisoning include chills, fever, headache and vomiting. (11 May 1997) |
| fescue poisoning | Poisoning by a toxic principle in tall fescue grass; mainly a disease of cattle, but sheep are sometimes affected; lameness in the hind feet is first noticed, followed by necrosis of the extremities. Synonym: fescue poisoning. (05 Mar 2000) |
| fluoride poisoning | Gen or unspecified fluoride; prefer /pois with specific fluoride term (12 Dec 1998) |
| food poisoning | The development of gastroenteritis secondary to the consumption of bacteria or their toxic byproducts. Onset of symptoms may occur anywhere from 30 minutes to 12 hours after the ingestion of the tainted foodstuffs. (27 Sep 1997) |
| lead poisoning | <pharmacology> An environment hazard (for example, from lead-containing paint, leaded gasoline,etc) capable of causing brain damage. (25 Jun 1999) |
| lecheguilla poisoning | A plant toxaemia of sheep and goats in western Texas, southeastern New Mexico, and northern Mexico caused by eating Agave lecheguilla; there is liver damage resulting in icterus, sometimes haemoglobinuria, and often death, and photosensitivity with oedema, swelling, and crusting of the face and ears. Synonym: swellhead. (05 Mar 2000) |
| active carbon dioxide | Activated carbon dioxide, a complex of N-carboxybiotin (biotin + CO2) and an enzyme; the form in which carbon dioxide is added to other molecules in carboxylations; e.g., to methylcrotonyl-CoA to form beta-methylglutaconyl in the catabolism of leucine, and to acetyl-CoA to form malonyl-CoA. See: acetyl-CoA carboxylase. (05 Mar 2000) |
| anomeric carbon | The reducing carbon of a sugar; C-1 of an aldose, C-2 of a 2-ketose. (05 Mar 2000) |
| arteriovenous carbon dioxide difference | <physiology> The difference in carbon dioxide content (in ml per 100 ml blood) between arterial and venous blood. (05 Mar 2000) |
| carbon | <chemistry, element> Sixth element (Z=6) in the periodic table, has 6 protons, often described as the basis of life on earth because of its chemical properties, has potential for use with silicon as a low-activation structural material for fusion reactors, in the form silicon carbide. Carbon tiles are often used in plasma-facing components because its low Z makes carbon a relatively nice impurity. It is also useful as a neutron moderator. See: low-activation materials, plasma-facing components. Abbreviation: C (13 Nov 1997) |
| carbon-11 | A cyclotron-produced, positron-emitting radioisotope of carbon with a half-life of 20.3 minutes; used in positron-emitting tomography. (05 Mar 2000) |
| carbon-12 | The standard of atomic mass, 98.90% of natural carbon. (05 Mar 2000) |
| carbon-13 | A stable natural isotope, 1.1% of natural carbon. (05 Mar 2000) |
| carbon-14 | A beta-emitter with a half-life of 5715 years, widely used as a tracer in studying various aspects of metabolism; naturally occurring 14C, arising from cosmic ray bombardment, is used to date relics containing natural carbonaceous materials. (05 Mar 2000) |
