| multidisciplinary | Of many disciplines. (16 Dec 1997) |
|---|---|
| multidose | <pharmacology> Occurring in or using multiple doses. (18 Nov 1997) |
| multidrug resistance | The insensitivity of various tumours to a variety of chemically related anticancer drugs; mediated by a process of inactivating the drug or removing it from the target tumour cells. (05 Mar 2000) |
| multidrug transporter | Closely related family (ABC transporters) of integral membrane glycoproteins that export a variety of solutes from the cytoplasm. (18 Nov 1997) |
| multienzyme | Referring to several enzymes; e.g., multienzyme complex. (05 Mar 2000) |
| multienzyme complex | Cluster of distinct enzymes catalysing consecutive reactions of a metabolic pathway, that remain physically associated through purification procedures. Multifunctional enzymes, found in eukaryotes, are a somewhat different phenomenon, since the several enzymic activities are associated with different domains of a single polypeptide. (18 Nov 1997) |
| multienzyme complexes | Systems of enzymes which function sequentially by catalyzing consecutive reactions linked by common metabolic intermediates; may involve simply a transfer of water molecules of hydrogen atoms or be associated with large supramolecular structures such as mitochondria or ribosomes. (12 Dec 1998) |
| multienzyme system | A group of related enzymes that operate in a particular metabolic pathway. (09 Oct 1997) |
| multifactorial | Referring to multiple factors. (12 Dec 1998) |
| multifactorial inheritance | Type of hereditary pattern seen with a combination of genetic factors, sometimes with environmental influence. Skin colour, for example, is multifactorially determined. (12 Dec 1998) |
| multifactorial or multigenic disorders | Genetic disorders resulting from the combined action of alleles of more than one gene (e.g., heart disease, diabetes, and some cancers). Although such disorders are inherited, they depend on the simultaneous presence of several alleles, thus the hereditary patterns are usually more complex than those of single- gene disorders. Compare single-gene disorders. (05 Mar 2000) |
| multifarious | 1. Having multiplicity; having great diversity or variety; of various kinds; diversified; made up of many differing parts; manifold. "There is a multifarious artifice in the structure of the meanest animal." (Dr. H. More) 2. <botany> Having parts, as leaves, arranged in many vertical rows. Origin: L. Multifarius; multus much, many. Cf. Bifarious. Source: Websters Dictionary (01 Mar 1998) |
| multifetation | <physiology> The formation of a foetus at the result of an impregnation occurring after another impregnation but before the birth of the offspring produced by it. This is possible only when there is a double uterus, or where menstruation persists up to the time of the second impregnation. "In then became a superfetation upon, and not an ingredient in, the national character." (Coleridge) Origin: Cf. F. Superfetation. Source: Websters Dictionary (01 Mar 1998) |
| multifid | <botany> Having many segments; cleft into several parts by linear sinuses; as, a multifid leaf or corolla. Origin: L. Multifidus; multus much, many + findere to split: cf. F. Multifide. Source: Websters Dictionary (01 Mar 1998) |
| multifidus | <anatomy, muscle> Origin, from the sacrum, sacroiliac ligament, mamillary processes of the lumbar vertebrae, transverse processes of thoracic vertebrae, and articular processes of last four cervical vertebrae; insertion, into the spinous processes of all the vertebrae up to and including the axis; action, rotates vertebral column; nerve supply, dorsal primary rami of spinal nerves. Synonym: musculus multifidus, intermediate layer of the transversospinalis muscles, musculus multifidus spinae. (05 Mar 2000) |
