| basic | 1. <chemistry> Relating to a base; performing the office of a base in a salt. Having the base in excess, or the amount of the base atomically greater than that of the acid, or exceeding in proportion that of the related neutral salt. Apparently alkaline, as certain normal salts which exhibit alkaline reactions with test paper. 2. <chemical> Said of crystalline rocks which contain a relatively low percentage of silica, as basalt. <chemistry> Basic salt, a salt formed from a base or hydroxide by the partial replacement of its hydrogen by a negative or acid element or radical.

| basic amino acid | An amino acid containing a second basic group (usually an amino group); e.g., lysine, arginine, ornithine. Synonym: dibasic amino acid. (05 Mar 2000) |
| basic anhydride | <chemical> A chemical (usually the oxide of a metal) which forms a base when it is mixed with water. (09 Oct 1997) |
| basic diet | A diet consisting mainly of fruits, vegetables, and milk (with minimal amounts of meat, fish, eggs, cheese, and cereals), which, when catabolised, leave an alkaline residue to be excreted in the urine. Synonym: acid-ash diet, basic diet. (05 Mar 2000) |
| basic dyes | Dye's which ionise in solution to give positively charged ions or cations; the auxochrome group is an amine which can form a salt with an acid like HCl; solutions are usually slightly acidic; examples include basic fuchsin and toluidine blue O. (05 Mar 2000) |
| basic electrical rhythm | A slow wave of depolarisation of smooth muscle from the fundus to the pylorus that coordinates gastric peristalsis and emptying. (05 Mar 2000) |
| basic esotropia | That type of esotropia not influenced by correction of refractive error. Synonym: basic esotropia. (05 Mar 2000) |
| basic exotropia | Exotropia in which the strabismus is the same for near and far vision. (05 Mar 2000) |
| basic fuchsin | A triphenylmethane dye whose dominant component is pararosanilin; an important stain in histology, histochemistry, and bacteriology. Synonym: diamond fuchsin. (05 Mar 2000) |
| basic fuchsin-methylene blue stain | <technique> A stain for intact epoxy sections; semi-thick sections of plastic-embedded tissues have nuclei stained purple; collagen, elastic lamina, and connective tissue are stained blue; mitochondria, myelin, and lipid droplets are stained red; cytoplasm, smooth muscle cells, axoplasm, and chrondroblasts are stained pink. (05 Mar 2000) |
| basic life support | Emergency cardiopulmonary resuscitation, control of bleeding, treatment of shock, acidosis, and poisoning, stabilization of injuries and wounds, and basic first aid. (05 Mar 2000) |
| basic oxide | A base anhydride; an oxide of an electropositive element or radical; it can combine with water to form a base. (05 Mar 2000) |
| basic personality | See: basic personality type. (05 Mar 2000) |
| basic personality type | An individual's unique, covert, or underlying personality propensities, whether or not they are behaviourally manifest or overt, personality characteristics of an individual which are also shared by a majority of the members of a social group. (05 Mar 2000) |
| basic polypeptide-activated protein kinase | <enzyme> Requires mn2+ for its activity; from bombyx mori; does not require cyclicamp, cyclicgmp or ca Registry number: EC 2.7.1.- Synonym: ba kinase (26 Jun 1999) |
| platelet basic protein | <protein> Protein that is the precursor of connective tissue activating peptide III and _ thromboglobulin. (18 Nov 1997) |
|---|---|
| myelin basic protein | <protein> Major component of the myelin sheath in mammalian CNS. Used as an antigen will induce a allergic encephalitis, possibly a model for some neurodegenerative disorders. (18 Nov 1997) |
| myelin basic protein kinase | <enzyme> Protein from pig brain activates ATP-mg-dependent protein phosphatase; a protein tau kinase; a multisubstrate kinase; in texts written as f subscript a Registry number: EC 2.7.1.- Synonym: protein phosphatase activator fa, glycogen synthase kinase 3, protein kinase f(a), gsk-3, gsk-3alpha, kinase f(a), gsk-3beta, mds1 gene product, p63(samk), src-activated mbp kinase, p63(mapk) (26 Jun 1999) |
| myelin basic proteins | A group of 7 proteins produced from a single gene by alternate splicing found in central and peripheral nervous system myelin. The major basic protein (mbp) has long been of interest because it is the antigen, that, when injected into an animal, elicits a cellular immune response that produces the CNS autoimmune disease called experimental allergic encephalomyelitis (encephalomyelitis, allergic). In the peripheral nervous system, myelin basic protein 18.5 kD is often referred to as the p1 protein. (12 Dec 1998) |
| haematoxylin-malachite green-basic fuchsin stain | <technique> A stain for epoxy resin-extracted sections; semi-thick sections have their plastic dissolved out and the residual tissue is stained sequentially with the various dyes; nuclei and astrocytes are purplish-pink and myelin, lipid droplets, nucleoli, and oligodendrocytes are bright blue-green. (05 Mar 2000) |
| fibroblast growth factor, basic | A single-chain polypeptide of approximately 15-16 kD which has been isolated from a variety of cells. It has a 55% amino acid residue identity to acidic fibroblast growth factor and has potent heparin-binding activity. However, in contrast to the acidic fibroblast growth factor, heparin does not potentiate the biological activities of bfgf. The growth factor is an extremely potent inducer of DNA synthesis in a variety of normal diploid mammalian cell types from mesoderm and neuroectoderm lineages and promotes cellular differentiation in vitro.
