| anaphase lag | Slowing or arrest in the normal migration of chromosomes during anaphase, resulting in such chromosomes being excluded from one of the daughter cells. (05 Mar 2000) |
|---|---|
| homeostatic lag | The interval in a homeostatic process between a change of the trait controlled and the appropriate response, due to afferent, efferent, and central components. The lag may be a pure random variable, e.g., the waiting time of an exponential process or the sum of several such processes taking any value greater than zero but with a mean considerably greater than zero; sometimes it may be deterministic or almost so and with a minimum sharply defined and greater than zero for anatomical reasons. For instance, the partial pressures of oxygen and carbon dioxide are controlled in the lungs but based on afferent information obtained from the carotid body that is already dated because of the circulation time of ten seconds or so between the two sites.

| nitrogen lag | The length of time after the ingestion of a given protein before the amount of nitrogen equal to that in the protein has been excreted in the urine. (05 Mar 2000) |
| jet lag | An imbalance of the normal circadian rhythm resulting from subsonic or supersonic travel through a varied number of time zones and leading to fatigue, irritability, and various functional disturbances. (05 Mar 2000) |
| lag | 1. One who lags; that which comes in last. "The lag of all the flock." 2. The fag-end; the rump; hence, the lowest class. "The common lag of people." (Shak) 3. The amount of retardation of anything, as of a valve in a steam engine, in opening or closing. 4. A stave of a cask, drum, etc. <machinery> Especially, one of the narrow boards or staves forming the covering of a cylindrical object, as a boiler, or the cylinder of a carding machine or a steam engine. 5. <zoology> See Graylag. Lag of the tide, the interval by which the time of high water falls behind the mean time, in the first and third quarters of the moon; opposed to priming of the tide, or the acceleration of the time of high water, in the second and fourth quarters; depending on the relative positions of the sun and moon. Lag screw, an iron bolt with a square head, a sharp-edged thread, and a sharp point, adapted for screwing into wood; a screw for fastening lags. Source: Websters Dictionary (01 Mar 1998) |
| 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) |
| acute-phase reaction | <immunology, rheumatology> Refers to the changes in synthesis of certain proteins within the serum during an inflammatory response, which provides rapid protection for the host against microorganisms via non-specific defense mechanisms. It consists of fever, an increase in inflammatory humoral factors, and an increased synthesis by hepatocytes of a number of proteins or glycoproteins usually found in the plasma; the reaction is mediated by endogenous pyrogens, the hypothalamus, adrenal hormones, and other factors.

| 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) |
| g1 phase | <cell biology, molecular biology> The period during interphase in the cell cycle between mitosis and the S phase (when DNA is replicated). Also known as the decision period of the cell, because the cell decides to divide when it enters the s phase. The G stands for gap. (09 Oct 1997) |
| g2 phase | <cell biology, molecular biology> The period during interphase in the cell cycle between the S phase (when DNA is replicated) and mitosis (when the nucleus, then cell, divides). at this time, the cell checks the accuracy of DNA replication and prepares for mitosis. The G stands for gap. (09 Oct 1997) |
| lag phase |
1. A state of apparent inactivity preceding a response; called also a latent phase.
