| cartilage matrix | The intercellular substance of cartilage consisting of fibres and ground substance. (05 Mar 2000) |
| matrix | Ground substance in which things are embedded or that fills a space (as for example the space within the mitochondrion). most common usage is for a loose meshwork within which cells are embedded (e.g. Extracellular matrix), although it may also be used of filters or absorbent material. (18 Nov 1997) |
| matrix-associated helicase | <enzyme> Component of the pre-mRNA splicing complex; has atpase activity and DNA helicase activity on a partially double-stranded DNA substrate in the 3'-5' direction Registry number: EC 2.7.7.- Synonym: helicase mah (26 Jun 1999) |
| matrix band | A metal or plastic band secured around the crown of a tooth to confine restorative material to be adapted into a prepared cavity. (05 Mar 2000) |
| matrix bands | Devices which provide an artificial temporary wall, or matrix, used in filling a prepared cavity. (12 Dec 1998) |
| matrix calculi | <radiology> Radiolucent, associated with Proteus infection, composition: 2/3 mucoprotein, 1/3 mucopolysaccharide see also: renal calculi (12 Dec 1998) |
| matrix calculus | A yellowish-white to light tan urinary calculus containing calcium salts, with the consistency of putty; composed chiefly of an organic matrix consisting of a mucoprotein and a sulfated mucopolysaccharide, and usually associated with chronic infection. (05 Mar 2000) |
| matrix Gla protein | A calcium binding protein. (05 Mar 2000) |
| matrix mitochondrialis | The substance occupying the space enclosed by the inner membrane of a mitochondrion; it contains enzymes, filaments of DNA, ribosomes, granules, and inclusions of protein crystals, glycogen, and lipid. Synonym: mitochondrial matrix. (05 Mar 2000) |
| matrix processing peptidase | <enzyme> From matrix fraction of rat liver mitochondria; cleaves mitochondrial protein precursors; inhibited by metal chelators and reactived by mn2+; classified as EC 3.4.24.64 Registry number: EC 3.4.24.- Synonym: mitochondrial processing peptidase, mitochondrial processing protease, alpha-mpp, beta-mpp, p-52 protein, rat, p-55 protein, rat, mas1 protein, yeast, mas2 protein, yeast (26 Jun 1999) |
| matrix proteins | Proteins of the outer layer of the cell wall of gram-negative bacteria. (18 Nov 1997) |
| matrix retainer | A mechanical device designed to hold a matrix around a tooth during restorative procedures, usually by engaging the ends of the matrix band and drawing the band tight. (05 Mar 2000) |
| matrix unguis | The area of the corium on which the nail rests; it is extremely sensitive and presents numerous longitudinal ridges on its surface. According to some anatomists, the nail bed is the portion covered by the body of the nail, the nail matrix being only the part on which the root of the nail rests. Synonym: matrix unguis, keratogenous membrane, nail matrix, onychostroma. (05 Mar 2000) |
