| 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) |
| accretionary growth | Growth by an increase of intercellular material. (05 Mar 2000) |
| appositional growth | Growth accomplished by the addition of new layers on those previously formed; e.g., the addition of lamellae in the formation of bone; it is the characteristic method of growth when rigid materials are involved. (05 Mar 2000) |
| auxetic growth | Growth by increase in the size of component cells. Synonym: intussusceptive growth. (05 Mar 2000) |
| bacterial growth | Growth of a bacterial culture either by increase in cell material or cell number. (05 Mar 2000) |
| B-cell differentiation/growth factors | Various substances, usually obtained from the supernatant of T-cell cultures, such as interleukin 4, 5, and 6. These substances are necessary for B-cell growth, maturation, and differentiation into plasma cells or B memory cells. (05 Mar 2000) |
| biphasic growth curve | <cell culture, microbiology> A particular type of growth curve seen in cultured microorganisms in which they have two exponential growth stages separated by a plateau phase. This double-hump curve is produced when the microbes are cultured using two carbon sources, one of which must be used up before the second can be used. (19 Jan 1998) |
| bovine growth hormone | <endocrinology> A hormone secreted by the bovine pituitary gland. It is used to increase milk production by improving the feed efficiency in dairy cattle. (14 Nov 1997) |
| brain-derived growth factor | <growth factor> Small basic protein purified from pig brain, a member of the family of neurotrophic factors that also includes Nerve Growth Factor and neurotrophin 3. In contrast to nerve growth factor, brain-derived neurotrophic factor is predominanantly (though not exclusively) localised in the CNS. It supports the survival of primary sensory neurons originating from the neural crest and ectodermal placodes that are not responsive to NGF. In the brain brain-derived neurotrophic factor has a trophic action on retinal, cholinergic, and dopaminergic neurons, and in the peripheral nervous system it acts on both motor and sensory neurons. Acronym: BDGF (12 Dec 1998) |
| capon-comb-growth test | A test for androgenic activity, based upon the stimulation of comb growth in capons (castrated cockerels) or immature roosters. Synonym: capon-comb-growth test, cock's comb test. (05 Mar 2000) |
| radial growth phase | The early pattern of growth of cutaneous malignant melanoma, in which tumour cells spread laterally in the epidermis. (05 Mar 2000) |
| vascular endothelial growth factor | A growth factor that is responsible for the growth of blood vessels. (12 Dec 1998) |
