| essential amino acid | <biochemistry> Those amino acids that cannot be synthesised by an organism and must therefore be present in the diet. The term is often applied anthropocentrically to those amino acids required by humans (Ileu, Leu, Lys, Met, Phe, Thr, Try, & Val), though rats need two more (Arg & His). (18 Nov 1997) |

| excitatory amino acid | <biochemistry> The naturally occurring amino acids L glutamate and L aspartate and their synthetic analogues, notably kainate, quisqualate and NMDA. They have the properties of excitatory neurotransmitters in the CNS, may be involved in long-term potentiation and can act as excitotoxins. at least three classes of EAA receptor have been identified, the agonists of the N type receptor are L aspartate, NMDA and ibotenate, the agonists of the Q type receptor are L glutamate and quisqualate, agonists of the K type are L glutamate and kainate. All three receptor types are found widely in the CNS and particularly the telencephalon, N and Q type receptors tend to occur together and may interact, their distribution is complementary to the K type receptors. The ion fluxes through the Q and K receptors are relatively brief, whereas the flux through the N type is longer and carries a significant amount of calcium. Additionally the N type receptor is blockaded by magnesium near the resting potential and thus shows voltage gated ion channel properties, leading to a regenerative response, this is why N type receptors have been linked to long-term potentiation. Invertebrate glutamate receptors may not have the same properties as those described above. (18 Nov 1997) |
| excitatory amino acid agents | Drugs used for their actions on any aspect of excitatory amino acid neurotransmitter systems. Included are drugs that act on excitatory amino acid receptors, affect the life cycle of excitatory amino acid transmitters, or affect the survival of neurons using excitatory amino acids. (12 Dec 1998) |
| excitatory amino acid agonists | Drugs that bind to and activate excitatory amino acid receptors. (12 Dec 1998) |
| excitatory amino acid antagonists | Drugs that bind to but do not activate excitatory amino acid receptors, thereby blocking the actions of agonists. (12 Dec 1998) |
| 1-carbamoyl-L-amino acid amidohydrolase | <enzyme> From bacillus stearothermophilus; amino acid sequence given in first source Registry number: EC 3.5.1.- Synonym: carbamoyl l-aa amidohydrolase, n-carbamyl-l-amino acid amidohydrolase (26 Jun 1999) |
| vesicular | 1. Composed of or relating to small, saclike bodies. 2. Pertaining to or made up of vesicles on the skin. Origin: L. Vesicula = a little bladder (18 Nov 1997) |
| vesicular appendage | A small fluid-filled cyst attached by a slender stalk to the fimbriated end of the uterine tube; a vestigial remnant of the embryonic mesonephric duct. Synonym: appendix vesiculosa, Morgagni's hydatid, morgagnian cyst, stalked hydatid, vesicular appendage. (05 Mar 2000) |
| vesicular appendices of uterine tube | A small fluid-filled cyst attached by a slender stalk to the fimbriated end of the uterine tube; a vestigial remnant of the embryonic mesonephric duct. Synonym: appendix vesiculosa, Morgagni's hydatid, morgagnian cyst, stalked hydatid, vesicular appendage. (05 Mar 2000) |
| vesicular exanthema | An extinct disease of swine caused by vesicular exanthema virus of swine, a member of the family Caliciviridae; it closely resembled foot-and-mouth disease and, in swine, was characterised by fever, loss of weight, and vesicles on the snout, tongue, and feet. (05 Mar 2000) |
| vesicular exanthema of swine | A calicivirus infection of swine characterised by hydropic degeneration of the oral and cutaneous epithelia. (12 Dec 1998) |
| vesicular exanthema of swine virus | The type species of the genus calicivirus, an RNA virus infecting pigs. The resulting infection is an acute febrile disease which is clinically indistinguishable from foot and mouth disease. Transmission is by contaminated food. (12 Dec 1998) |
| vesicular keratitis | Keratitis with coalescence of areas of epithelial corneal oedema. (05 Mar 2000) |
| vesicular keratopathy | Corneal epithelial oedema with formation of vacuoles. (05 Mar 2000) |
| vesicular mole | <gynaecology, oncology, tumour> A relatively rare mass or tumour that can form within the uterus at the beginning of a pregnancy. The cause of hydatidiform mole is unknown. Symptoms include vaginal bleeding, uterine growth, nausea and vomiting. Some hydatidiform moles may become malignant (cancerous) where they are referred to as a choriocarcinoma. Incidence: 1 in 1,500 births. (02 Jan 1998) |
