| pathologic startle syndromes | A group of disorders characterised by markedly exaggerated startle reflex and other exaggerated stimulus-induced responses. Includes hyperexplexia and probably latah and the jumping Frenchman of Maine syndrome. (05 Mar 2000) |
|---|---|
| constriction, pathologic | The condition of an anatomical structure's being constricted beyond normal dimensions. (12 Dec 1998) |
| neovascularization, pathologic | Proliferation of blood vessels in tissue not normally containing them, or proliferation of blood vessels of a different kind than usual in tissue. It includes angiogenesis in tumour growth, diabetic retinopathy, haemangiomas, arthritis, and psoriasis. (12 Dec 1998) |
| decalcification, pathologic | The loss of calcium salts from bones and teeth. Bacteria may be responsible for this occurrence in teeth. Old age may be a factor contributing to calcium loss, as is the presence of diseases such as rheumatoid arthritis. (12 Dec 1998) |
| diagnosis, pathologic | A diagnosis, sometimes made postmortem on the basis of the study of tissue and/or organs. (27 Sep 1997) |
| dilatation, pathologic | The condition of an anatomical structure's being dilated beyond normal dimensions. (12 Dec 1998) |
| 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) |
