| APV | abnormal posterior vector |
| host-vector system | A combination of a bacterial host cell (i.e. A specific strain) and a virus vector (i.e. A particular bacteriophage strain) which work well together for DNA cloning. (09 Oct 1997) |
|---|---|
| shuttle vector | <molecular biology> Cloning vector that replicate in cells of more than one organism, for example E. Coli and yeast. This combination allows DNA from yeast to be grown in E. Coli and tested directly for complementation in yeast. Shuttle vectors are constructed so that they have the origins of replication of the various hosts. (18 Nov 1997) |
| spatial vector | A cardiac vector represented in more than one plane simultaneously; two-or three-dimensional orientation of a vector. (05 Mar 2000) |
| instantaneous vector | The resultant vector of the heart's action currents at any given moment, usually represented as an arrow of appropriate direction and magnitude. (05 Mar 2000) |
| expression vector | <molecular biology> A cloning vector that contains the necessary regulatory sequences to allow transcription and translation of a cloned gene or genes and thus transcribe and clone DNA. (13 Nov 1997) |
| arithmetic mean | The mean calculated by adding a set of values and then dividing the sum by the number of values. (05 Mar 2000) |
| calculated mean organism | A hypothetical organism whose characters are the means of both the positive and negative characters of the organism's which belong to the same taxon as the CMO, as opposed to the hypothetical mean. Organism. (05 Mar 2000) |
| geometric mean | The mean calculated as the antilogarithm of the arithmetic mean of the logarithms of the individual values; it can also be calculated as the nth root of the product of n values. (05 Mar 2000) |
| geometric mean diameter | A measure of the central tendency of particle size composition of substrate materials sometimes used as an index of the quality of spawning gravels. Also referred to as D50 size. (09 Oct 1997) |
| mean | <statistics> Average value calculated by taking the sum of all values and dividing by the total number of values. (05 Jan 1998) |
| mean annual increment | The annual average growth rate for a tree, computed over its entire life cycle. (05 Dec 1998) |
| mean arterial pressure | <cardiology, physiology> The average value for arterial pressure. Systolic pressure + diastolic pressure divided by 2. (27 Sep 1997) |
| mean calorie | One hundredth of the energy required to raise the temperature of 1 g of water from 0캜 to 100캜. (05 Mar 2000) |
| mean corpuscular haemoglobin | The haemoglobin content of the average red cell, calculated from the haemoglobin therein and the red cell count, in erythrocyte indices. (05 Mar 2000) |
| mean corpuscular haemoglobin concentration | Hgb/Hct;the average haemoglobin concentration in a given volume of packed red cells, calculated from the haemoglobin therein and the haematocrit, in erythrocyte indices. (05 Mar 2000) |
