| differential centrifugation | A technique for separating organellesor other differently-sized cellcomponents in a centrifuge, particles of the same size and weight willsettle out into common layers. (09 Oct 1997) |
|---|---|
| equilibrium centrifugation | A type of density gradient centrifugation used to separate proteins or nucleic acids from a mixture. (09 Oct 1997) |
| zinc sulfate flotation centrifugation method | A flotation method in which the faecal specimen is suspended in tap water, strained through wet gauze, centrifuged, resuspended in tap water, washed and recentrifuged several times, and then suspended in 33% solution of zinc sulfate and centrifuged at top speed for 45 to 60 sec; a bacteriologic loop may be used to pick up the surface layer, which contains protozoan cysts and helminth eggs. (05 Mar 2000) |
| zone centrifugation | <technique> High-speed centrifugation inwhich molecules float at a point wheretheir density equals that in a gradient of cesium chloride or sucrose. (12 Jan 1998) |
| average flow rate | <physiology> The flow rate determined by dividing the total volume passed in a time period divided by the time period, usually quoted in mls per minute. (05 Mar 2000) |
| Bingham flow | The flow characteristics exhibited by a Bingham plastic. (05 Mar 2000) |
| blood flow velocity | A value equal to the total volume flow divided by the cross-sectional area of the vascular bed. (12 Dec 1998) |
| gene flow | The movement of genes from one population to another viainterbreeding. (09 Oct 1997) |
| maximal expiratory flow rate | <chest medicine, physiology> Measurement of rate of airflow during the first liter expired after the first 200 ml have been exhausted during a forced vital capacity determination. Common abbreviations are MEFR, FEF 202-1200, and fef 0.2-1.2. Acronym: MEFR (21 Jun 2000) |
| maximal expiratory flow-volume curve | <chest medicine> Curves depicting maximal expiratory flow in liters/second at each point of lung inflation (expressed in liters or percentage of forced vital capacity) during a forced vital capacity determination. Common abbreviation is mefv. (12 Dec 1998) |
| maximal midexpiratory flow rate | Measurement of rate of airflow over the middle half of a forced vital capacity determination (from the 25 percent level to the 75 percent level). Common abbreviations are mmfr and fef 25%-75%. (12 Dec 1998) |
| renal blood flow, effective | The amount of blood flowing to the parts of the kidney that are involved with the production of constituents of urine. It is that portion of the total renal blood flow that perfuses functional renal tissue (e.g., the glomeruli). It should be differentiated from renal plasma flow, effective which is based on the amount of plasma rather than on total renal blood. (12 Dec 1998) |
| renal plasma flow | <physiology> The amount of plasma that perfuses the kidneys per unit time, approximately 10% greater than effective renal plasma flow. It should be differentiated from the renal blood flow which refers to the total volume of blood flowing through the renal vasculature, while the renal plasma flow refers to the rate of plasma flow. (12 Dec 1998) |
| peak expiratory flow | The maximum flow at the outset of forced expiration, which is reduced in proportion to the severity of airway obstruction, as in asthma. (05 Mar 2000) |
| peak expiratory flow rate | Measurement of the maximum rate of airflow attained during a forced vital capacity determination. Common abbreviations are pefr and pfr. (12 Dec 1998) |
