| yttrium radioisotopes | Unstable isotopes of yttrium that decay or disintegrate emitting radiation. Y atoms with atomic weights 82-88 and 90-96 are radioactive yttrium isotopes. (12 Dec 1998) |
|---|---|
| zinc radioisotopes | Unstable isotopes of zinc that decay or disintegrate emitting radiation. Zn atoms with atomic weights 60-63, 65, 69, 71, and 72 are radioactive zinc isotopes. (12 Dec 1998) |
| krypton radioisotopes | Unstable isotopes of krypton that decay or disintegrate emitting radiation. Kr atoms with atomic weights 74-77, 79, 81, 85, and 87-94 are radioactive krypton isotopes. (12 Dec 1998) |
| fluorine radioisotopes | Unstable isotopes of fluorine that decay or disintegrate emitting radiation. F atoms with atomic weights 17, 18, and 20-22 are radioactive fluorine isotopes. (12 Dec 1998) |
| benzoylpas calcium | 4-Benzamidosalicylic acid calcium salt;an antituberculous agent. (05 Mar 2000) |
| calcium | <element> An element taken in through the diet that is essential for a variety of bodily functions, such as neurotransmission, muscle contraction and proper heart function. Imbalances of calcium can lead to many health problems and excess calcium in nerve cells can cause their death. (22 May 1997) |
| calcium-45 | <radiobiology> Most easily available of the radioactive calcium-45 isotopes; beta-emitter with a half-life of 162.7 days; used as a tracer. (05 Mar 2000) |
| calcium-47 | <radiobiology> A radioisotope of calcium with a half-life of 4.54 days, used in the diagnosis of disorders of calcium metabolism. (05 Mar 2000) |
| calcium alginate | A topical haemostatic. (05 Mar 2000) |
| calcium aminosalicylate | The calcium salt of p-aminosalicylic acid, with the same uses. (05 Mar 2000) |
| calcium antagonist | calcium channel-blocking agent |
| calcium ATPase | <enzyme> Usually used of the calcium pumping ATPase present in high concentration as an integral membrane protein of the sarcoplasmic reticulum of muscle. This pump lowers the cytoplasmic calcium level and causes contraction to stop. Normal function of the pump seems to require a local phospholipid environment from which cholesterol is excluded. (18 Nov 1997) |
| calcium benzoylpas | Calcium 4-benzamidosalicylate;an antituberculous agent. (05 Mar 2000) |
| calcium-binding protein | <biochemistry> There are two main groups of calcium binding proteins, those that are similar to calmodulin and are called EF hand proteins and those that bind calcium and phospholipid (e.g. Lipocortin) and that have been grouped under the generic name of annexins. Many other proteins will bind calcium, although the binding site usually has considerable homology with the calcium-binding domains of calmodulin. They can act as transport proteins, regulator proteins or activator proteins. There is also a vitamin D-dependent variant which is a protein that plays a fundamental role in the vitamin d mediated transport of calcium in reptiles, amphibians, birds and mammals. It is found in the intestine, kidneys, egg shell gland, brain, and possibly other organs. Its molecular weight is species dependent. (12 May 2002) |
| calcium bromide | Used to meet the same indications as potassium bromide. (05 Mar 2000) |
