| transferases (other substituted phosphate groups) | <enzyme> A class of enzymes that transfers substituted phosphate groups. Registry number: EC 2.7.8 (12 Dec 1998) |
| vertical overlap | The extension of the upper teeth over the lower teeth in a vertical direction when the opposing posterior teeth are in contact in centric occlusion, the distance that teeth lap over their antagonists vertically, especially for the distance that the upper incisal edges drop below the lower ones, but may also describe the vertical relations of opposing cusps, the relationship of the maxillary incisors to the mandibular incisors when the incisal edges pass each other in centric occlusion. Synonym: overbite. (05 Mar 2000) |
| horizontal overlap | The projection of the upper anterior and/or posterior teeth beyond their antagonists in a horizontal direction. Synonym: overjet, overjut. (05 Mar 2000) |
| overlap | 1. The lapping of one thing over another; as, an overlap of six inches; an overlap of a slate on a roof. 2. <geology> An extension of geological beds above and beyond others, as in a conformable series of beds, when the upper beds extend over a wider space than the lower, either in one or in all directions.

| overlap hybridization | A procedure to find and sequence a gene whose approximate position in a chromosome is known by classical genetic linkage studies. Starting with the known sequence of a gene shown by classical genetics to be near to the novel gene, new clones are picked from a genomic library by hybridisation with a short probe generated from the appropriate end of the known sequence. The new clones are then sequenced, new probes generated and the process repeated until the gene of interest is reached. (18 Nov 1997) |
| overlap index | <cell biology> A measure of the extent to which a population of cells in culture forms multilayers. The predicted amount of overlapping is calculated knowing the cell density, the projected area of the nucleus (usually) and assuming a Poisson distribution. The actual overlap is measured on fixed and stained preparations and the ratio of actual/predicted is derived. A value of 1 implies a random distribution with no constraint on overlapping, normal fibroblasts may have values as low as 0.05. Although a useful measure it does not unambiguously indicate the reason for the effect, which may be contact inhibition of locomotion or differential adhesion of cells between substratum and other cells. (18 Nov 1997) |
| androgen resistance syndromes | A class of disorders associated with 5a-steroid reductase deficiency, testicular feminization, and related disorders. Compare: steroid 5a-reductase, Reifenstein's syndrome, infertile male syndrome, testicular feminization syndrome. (05 Mar 2000) |
| aortic arch syndromes | Any of a group of disorders leading to occlusion of the arteries arising from the aortic arch. Such occlusion may be caused by atherosclerosis, arterial embolism, syphilitic or tuberculous arteritis, etc. (12 Dec 1998) |
| malabsorption syndromes | General term for syndromes of malnutrition due to failure of normal intestinal absorption of nutrients. (12 Dec 1998) |
| paraneoplastic syndromes | In patients with neoplastic diseases a wide variety of clinical pictures which are indirect and usually remote effects produced by tumour cell metabolites or other products. (12 Dec 1998) |
| 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) |
| chromosomal instability syndromes | A group of mendelian conditions associated with chromosomal instability and breakage in vitro, they often manifest an increased tendency to certain types of malignancies. See: Bloom's syndrome, fragile X syndrome, xeroderma pigmentosum. (05 Mar 2000) |
| compartment syndromes | Conditions in which increased pressure within a limited space compromises the circulation and function of tissue within that space. Compartmentation involves mainly the leg but also involved are the forearm, arm, thigh, shoulder, and buttock. Some of the causes of increased pressure are trauma, tight dressings, haemorrhage, and exercise. Sequelae include nerve compression, paralysis, and contracture. (12 Dec 1998) |
| myelodysplastic syndromes | Conditions in which the bone marrow shows qualitative and quantitative changes suggestive of a preleukaemic process, but having a chronic course that does not necessarily terminate as acute leukaemia. (12 Dec 1998) |
