| methacrylate resin | Polymerised methacrylic acid;a translucent plastic material, used for the manufacture of various medical appliances, surgical instruments, and seating components used in total joint replacement; it possesses the optical properties of fused quartz, and is readily molded when heated; formerly used in electron microscopy for embedding tissues, now superseded by epoxy resin's. (05 Mar 2000) |
| polyhydroxyethyl methacrylate | <chemical> Poly(2-hydroxyethyl methacrylate). A biocompatible, hydrophilic, inert gel that is permeable to tissue fluids. It is used as an embedding medium for microscopy, as a coating for implants and prostheses, for contact lenses, as microspheres in adsorption research, etc. Chemical name: 2-Propenoic acid, 2-methyl-, 2-hydroxyethyl ester, homopolymer (12 Dec 1998) |
| polymethyl methacrylate | <chemical> Polymerised methyl methacrylate monomers which are used as sheets, moulding, extrusion powders, surface coating resins, emulsion polymers, fibres, inks, and films . This material is also used in tooth implants, bone cements, and hard corneal contact lenses. Pharmacological action: antimutagenic agents, bone cements, vasodilator agents. (12 Dec 1998) |
| active methyl | A methyl group attached to a quaternary ammonium ion or a tertiary sulfonium ion that can take part in transmethylation reactions; e.g., methyl groups in choline and in S-adenosyl-l-methionine, which are thus methyl donors. (05 Mar 2000) |
| aklanonic acid methyl ester cyclase | <enzyme> Catalyses the formation of aklaviketone from aklanonic acid methyl ester; involved in daunomycin biosynthesis; see also daunorubicin-doxorubicin polyketide synthase Registry number: EC 5.- Synonym: aame cyclase, daud protein, daud gene product, dnrd protein, dnrd gene product (26 Jun 1999) |

| alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid | <chemical> Alpha-amino-2,3-dihydro-5-methyl-3-oxo-4-isoxazolepropanoic acid. An ibotenic acid homolog and glutamate agonist. The compound is the defining agonist for the ampa subtype of glutamate receptors (receptors, ampa). It has been used as a radionuclide imaging agent but is more commonly used as an experimental tool in cell biological studies. Pharmacological action: excitatory amino acid agonists. Chemical name: 4-Isoxazolepropanoic acid, alpha-amino-2,3-dihydro-5-methyl-3-oxo- (12 Dec 1998) |

| Mann's methyl blue-eosin stain | <technique> A stain useful for anterior pituitary and viral inclusion bodies; a mixture of the two dyes stains alpha cell granules red, beta cell granules dark blue, chromophobes gray to pink, colloid red, erythrocytes orange-red, and collagen fibres blue; this method is also useful for enterochromaffin, goblet, Paneth, and pancreatic islet cells; Negri bodies appear red while their nuclei and central granules are blue. (05 Mar 2000) |
| receptors, n-methyl-d-aspartate | A class of ionotropic glutamate receptors characterised by affinity for n-methyl-d-aspartate. Nmda receptors have an allosteric binding site for glycine which must be occupied for the channel to open efficiently and a site within the channel itself to which magnesium ions bind in a voltage-dependent manner. The positive voltage dependence of channel conductance and the high permeability of the conducting channel to calcium ions (as well as to monovalent cations) are important in excitotoxicity and neuronal plasticity. (12 Dec 1998) |
| methyl | <chemistry> Specific reference to the methyl group is made when macromolecules are modified after synthesis by enzymic addition of methyl groups. The group is transferred to nucleic acids and proteins. See: methyl transferase and DNA methylation. (18 Nov 1997) |
| methyl accepting chemotaxis protein | Methyl accepting chemotaxis proteins. Proteins of the inner cytoplasmic face of the bacterial plasma membane with which the receptors of the outer face interact. Four different MCPs are known in E. Coli, each with a separate set of receptors. Can be methylated at various sites, methylation is part of the adaptation to the signal. Although important intermediate signal integration sites, they are not directly connected to the motor. (18 Nov 1997) |

| methyl methacrylate |
MMA in its liquid form has been banned for use in the nail industry due to the severity of allergic reaction and damage to the natural nail plate. It adheres so tightly to the nail plate that it can literally rip the nail plate from the nail bed due to heavy pressure from a blow or trauma to the nail. MMA is so hard that it cannot be safely removed from the nail plate by soaking in any form of remover -- it must be filed from the nail plate with a heavy abrasive.
