| late rickets | <pathology> A condition marked by softening of the bones (due to impaired mineralisation, with excess accumulation of osteoid), with pain, tenderness, muscular weakness, anorexia and loss of weight, resulting from deficiency of vitamin D and calcium. Origin: Gr. Malakia = softness (18 Nov 1997) |
|---|---|
| late seizure | A seizure that occurs greater than one week after a craniocerebral trauma or CNS insult. (05 Mar 2000) |
| late seral species | Shade tolerant species, primarily vine maple shrubs and western red cedar and western hemlock trees. These species follow the mid seral species in natural succession. (05 Dec 1998) |
| late seral treatment | A treatment in which late seral species will be established after thinning. (05 Dec 1998) |
| late-successional forest | Forest seral stages which include mature and old- growth age classes. (05 Dec 1998) |
| late-successional reserve | An area of forest where the management objective is to protect and enhance conditions of late successional and old-growth forest ecosystems. (05 Dec 1998) |
| late syphilis | Involvement of the cardiovascular or central nervous system, or the development of a gumma in any organ, due to infection with Treponema pallidum; usually several years to 2-3 decades after the initial infection. Synonym: tertiary syphilis. (05 Mar 2000) |
| late systole | The interval in the cardiac rhythm immediately preceding diastole. Synonym: late systole. (05 Mar 2000) |
| accelerated phase of leukaemia | Refers to chronic myelogenous leukaemia that is progressing. The number of immature, abnormal white blood cells in the bone marrow and blood is higher than in the chronic phase, but not as high as in the blast phase. (12 Dec 1998) |
| acceleration phase | <cell biology, cell culture> A period of increasing growth before the log phase in a culture of microbes. After the culture is started on a medium, at first there is no growth (the lag phase) and then the microbes start to gradually grow (acceleration phase) until they reach a constant maximum rate of growth (log phase). (15 Jan 1998) |
| acute-phase protein | <haematology> These plasma proteins (in addition to fibrinogen) increase 25% or more in response to inflammation and injury are under direct control of interleukin-6 (IL-6) (hepatocyte-stimulating factor). Other proteins which increase are ceruloplasmin, C3 and C4 which increase 50% or more; alpha-1 acid glycoprotein, alpha-1 antitrypsin, haptoglobin and fibrinogen (the major determinant of viscosity 1 ) which increase two- to fourfold; C-reactive protein (CRP) and serum amyloid A which increase several hundred-fold. Despite long-held clinical opinion to the contrary, available data indicate that neither ESR nor measurement of specific acute-phase reactants are useful in excluding underlying infection or inflammation regardless of the pretest probability. These proteins are secreted into the blood in increased or decreased quantities by hepatocytes in response to trauma, inflammation, or disease. They can serve as inhibitors or mediators of the inflammatory processes. Certain acute-phase proteins have been used to diagnose and follow the course of diseases or as tumour markers. See also: amyloid, c-reactive protein, erythrocyte sedimentation rate, viscosity. (25 Jun 1999) |
| anal phase | In psychoanalytic personality theory, the stage of psychosexual development, occurring when a child is between 1 and 3 years, during which activities, interests, and concerns are centreed around the anal zone. (05 Mar 2000) |
| aqueous phase | The water portion of a system consisting of two liquid phase's, one mainly water, the other a liquid immiscible with water (e.g., benzene, ether). (05 Mar 2000) |
| blast phase | Refers to advanced chronic myelogenous leukaemia. In this phase, the number of immature, abnormal white blood cells in the bone marrow and blood is extremely high. Also called blast crisis. (12 Dec 1998) |
| g0 phase | Phase of the cell cycle where cells exist in a quiescent state. These cells have unduplicated DNA, degraded RNA and protein, and low enzyme activity. The ability to switch between g0 and g1 (and vice versa) determines the post-embryonic cell proliferation rate and is defectively controlled in neoplastic cells. (12 Dec 1998) |
