| Doppler colour flow | A computer-generated colour image produced by Doppler ultrasonography in which different directions of flow are represented by different hues. This technique is typically used to examine blood flow when evaluating heart disease. Where obstructions (for instance, arterial plaques) exist, blood flow will alter according to the principles of fluid mechanics. Eddies and reversals are readily apparent on the colour image. See: Doppler ultrasonography. (05 Mar 2000) |

| body surface potential mapping | Recording of regional electrophysiological information by analysis of surface potentials to give a complete picture of the effects of the currents from the heart on the body surface. It has been applied to the diagnosis of old inferior myocardial infarction, localization of the bypass pathway in wolff-parkinson-white syndrome, recognition of ventricular hypertrophy, estimation of the size of a myocardial infarct, and the effects of different interventions designed to reduce infarct size. The limiting factor at present is the complexity of the recording and analysis, which requires 100 or more electrodes, sophisticated instrumentation, and dedicated personnel. (12 Dec 1998) |
| cardiac mapping | A method by which local cardiac potentials are spatially depicted in an integrated manner as a function of time (isochrone map) or potential (isopotential map). (05 Mar 2000) |
| gene mapping | Determination of the relative positions of genes on a DNA molecule (chromosome or plasmid) and of the distance, in linkage units or physical units, between them. (09 Oct 1997) |
| mapping | See: gene mapping, linkage map, physical map. (09 Oct 1997) |
| mapping function | In linkage analysis, a formula that converts the recombination fraction (which is on the probability scale) into map distance (in morgans). (05 Mar 2000) |
| mapping, gene | Charting the positions of genes on chromosome and learning the distance, in linkage units or physical units, between genes. (12 Dec 1998) |
| genetic mapping | Determination of the relative positions of genes on a DNA molecule (chromosome or plasmid) and of the distance, in linkage units or physical units, between them. (14 Nov 1997) |
| restriction mapping | Use of restriction endonucleases to analyze and generate a physical map of genomes or genes. The nucleotide sequence determined is often then translated into an amino acid sequence, providing a means for sequencing the protein for which the gene codes, or for which the mRNA is a messenger. (12 Dec 1998) |
| peptide mapping | Two-dimensional separation and analysis of peptides. (12 Dec 1998) |
| chromosome mapping | The mapping of the relative locations of genes on a chromosome by analysing linkage frequencies (how often different genes are inherited together) and crossover frequencies (how often different combinations of three or more genes are inherited) or recombination frequencies. (09 Oct 1997) |
| S1 nuclease mapping | A method for locating the 5' end of a transcript in a mixture of RNA. (05 Mar 2000) |
| heteroduplex mapping | <molecular biology> Heteroduplex mapping is a lab technique used to locate a particular sequence of nucleotides. It involves making a heteroduplex by pairing the unknown nucleic acid strand with a reference strand which has a known sequence. (09 Oct 1997) |
| nucleotide mapping | Two-dimensional separation and analysis of nucleotides. (12 Dec 1998) |
| epitope mapping | Methods used for studying the interactions of antibodies with specific regions of protein antigens. Important applications of epitope mapping are found within the area of immunochemistry. (12 Dec 1998) |
