| selenium deficiency | deficiency of the essential mineral selenium causes keshan disease, a fatal form of cardiomyopathy (disease of the heart muscle) first observed in keshan province in china and since found elsewhere. According to the national academy of sciences, the recommended dietary allowances of selenium are 70 milligrams per day for men and 55 milligrams per day for women. Food sources of selenium include seafoods, some meats such as kidney and liver, and some grains and seeds (12 Dec 1998) |
| selenium excess | Too much of the mineral selenium may cause reversible changes in the hair (balding) and nails, garlic odour to the breath, intestinal distress, weakness and slower mentation (slowed mental functionning). According to the national academy of sciences, the recommended dietary allowances of selenium are 70 milligrams per day for men and 55 milligrams per day for women. (12 Dec 1998) |
| selenium poisoning | Chronic poisoning of horses, cattle, and swine, caused by ingestion of grains and forage raised on soils high in selenium; it occurs only in arid regions, from eating certain plants which are selenium accumulators. (05 Mar 2000) |
| selenium radioisotopes | Unstable isotopes of selenium that decay or disintegrate emitting radiation. Se atoms with atomic weights 70-73, 75, 79, 81, and 83-85 are radioactive selenium isotopes. (12 Dec 1998) |
| selenium sulfide | A mixture of crystalline selenium monosulfide and solid solutions of selenium and sulfur in an amorphous form, containing 52 to 55.5% Se; used in the treatment of seborrhoea of the scalp or dandruff; it is applied to the scalp as a suspension. (05 Mar 2000) |
| selenium transferase | <enzyme> Converts phosphoseryl-trna to selenocysteinyl-trna; product of sela gene; converts seryl-trna(sec)(uca) to selenocysteyl-trna(sec)(uca) in pyridoxal-phosphate dependent reaction Registry number: EC 2.- Synonym: se-transferase, selenocysteine synthase (26 Jun 1999) |
