| multiple carboxylase deficiency | Abnormalities in carbohydrate and branched-chain amino acid catabolism that are responsive to biotin therapy. It may be due to deficiency of propionyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, biotinidase, or propionyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, and pyruvate carboxylase. (12 Dec 1998) |

| multiple endocrine deficiency syndrome | <syndrome> Acquired deficiency of the function of several endocrine glands, usually on an auto-immune basis. Synonym: multiple glandular deficiency syndrome. (05 Mar 2000) |
| multiple glandular deficiency syndrome | <syndrome> Acquired deficiency of the function of several endocrine glands, usually on an auto-immune basis. Synonym: multiple glandular deficiency syndrome. (05 Mar 2000) |
| multiple sulfatase deficiency | An inherited disorder (autosomal recessive) in which there is a failure to hydrolyze sulfatides and sulfated mucopolysaccharides; this failure leads to their accumulation in neural and extraneural tissues causing demyelination, sulfatiduria, facial and skeletal dysmorphism, etc. (05 Mar 2000) |
| actinide elements | Those elements with atomic numbers 89 to 103, corresponding to the lanthanides in the Periodic Table. Synonym: actinide elements. Origin: actinium, first element of the series (05 Mar 2000) |
| alkaline earth elements | Those element's in the family Be, Mg, Ca, Sr, Ba, and Ra, the hydroxides of which are highly ionised and hence alkaline in water solution. (05 Mar 2000) |
| alu elements | <molecular biology> A set of closely related genetic sequences, each about 300 base pairs long, in the human genome. There are 500,000 to 600,000 copies widely dispersed among all 46 chromosomes: They act as markers for human DNA sequences, although their function in the genome is unknown. The DNA fragments containing the Alu elements are formed by digesting genomic DNA with the restriction endonuclease Alu I. (14 Nov 1997) |
| rare earth elements | Those elements with atomic numbers 57-71 which closely resemble one another chemically and were once difficult to separate from one another. Synonym: rare earth elements. Origin: Lanthanum, first element of the series (05 Mar 2000) |
| P elements | A class of transposable elements in Drosophila responsible for hybrid dysgenesis; utilised as tools for introducing genes into new locations in the genome. (05 Mar 2000) |
| copia elements | A mobile genetic element with retrovirus-like sequence organization. (05 Mar 2000) |
| short interspersed elements | Repetitive sequences of DNA of about 300 base pairs in length that occur about every 3000-5000 bp in the genome. (05 Mar 2000) |
| nutrient | 1. Nourishing, affording nutriment. 2. A nutritious substance, food or a component of food. Origin: L. Nutriens (18 Nov 1997) |
| nutrient agar | A simple solid medium containing beef extract, peptone, agar, and water; used for growing many common heterotrophic bacteria. (05 Mar 2000) |
| nutrient arteries of humerus | Origin, deep brachial; distribution, the medullary cavity of the humerus. Synonym: arteriae nutriciae humeri. (05 Mar 2000) |
| nutrient artery | <anatomy, artery> An artery of variable origin that supplies the medullary cavity of a long bone. Synonym: arteria nutricia, nutrient vessel. (05 Mar 2000) |
