| atrial capture beat | The cardiac cycle resulting when, after a period of A-V dissociation, the atria regain control of the ventricles; atrial depolarisation due to retrograde transmission from a ventricular ectopic beat or an electronically paced ventricular impulse. (05 Mar 2000) |

| boron neutron capture therapy | A technique for the treatment of neoplasms, especially gliomas and melanomas in which boron-10, an isotope, is introduced into the target cells followed by irradiation with thermal neutrons. (12 Dec 1998) |
| capture | Catching and holding a particle or an electrical impulse originating elsewhere. Origin: L. Capio, pp. -tus, to take, seise Atrial capture, control of the atria for one or more beats after a period of independent beating, as in complete A-V block or in junctional or ventricular ectopic beats or tachycardias by a retrograde impulse. Electron capture, a mode of radioactive disintegration, in which an orbital electron, usually from the K shell, is captured by the nucleus, converting a proton into a neutron with ejection of a neutrino and emission of a gamma ray, and emission of characteristic X-rays as the missing K-shell electron is replaced. Synonym: K capture. (05 Mar 2000) |
| capture-recapture method | Originally, a technique developed by biologists to track wild animal populations; now adapted for epidemiological studies of elusive human populations (e.g., prostitutes, teen runaways, IV drug users).By comparing data from several independent overlapping sample frames, it is possible to adjust for missing cases and to generate estimates of the prevalence of a given condition, for example, AIDS infection. (05 Mar 2000) |
| ventricular capture | Capture of the ventricle(s) by an impulse arising in the atria or A-V junction. (05 Mar 2000) |
| neutron capture therapy | A technique for the treatment of neoplasms in which an isotope is introduced into target cells followed by irradiation with thermal neutrons. (12 Dec 1998) |
| IgM antibody capture ELISA | Developed to impart significant improvement in assay specificity to indirect ELISA procedures for IgM isotype antibodies. Solid-phase support (usually microtitre plate wells) are coated with anti-human IgM antibodies capable of binding all IgM isotype antibodies present in the specimen. Reagent antigen is then added, followed by enzyme-labelled antigen-specific antibodies. If IgM antibodies specific for the antigen in question are present, the "sandwich" complex will result in enzymatic colour-change proportional to the concentration of IgM-specific antibody present. This technique appears to be the method of choice in many highly specific and more sensitive assays for IgM infectious disease antibodies. Acronym: MAC ELISA (05 Mar 2000) |
| electron capture | <radiobiology> Nuclear decay process whereby a proton in the nucleus absorbs an orbiting electron and converts to a neutron. (09 Oct 1997) |
| escape-capture bigeminy | Paired beats, each couplet consisting of an escape beat followed by a conducted sinus beat. (05 Mar 2000) |
| K capture | <radiobiology> Nuclear decay process whereby a proton in the nucleus absorbs an orbiting electron and converts to a neutron. (09 Oct 1997) |
| binary fission | <cell biology> Division of a cell into two daughter cells after DNA replication and nuclear division (mitosis). A form of asexual reproduction. (09 Oct 1997) |
| bud fission | 1. <biology> The formation of a new individual, either animal or vegetable, by a process of budding; an asexual method of reproduction; gemmulation; gemmiparity. See Budding. 2. <botany> The arrangement of buds on the stalk; also, of leaves in the bud. Origin: Cf. F. Gemmation. Source: Websters Dictionary (01 Mar 1998) |
| multiple fission | Division of the nucleus, simultaneously or successively, into a number of daughter nuclei, followed by division of the cell body into an equal number of parts, each containing a nucleus. (05 Mar 2000) |
| simple fission | Division of the nucleus and then the cell body into two parts. See: binary fission. (05 Mar 2000) |
| nuclear fission | Nuclear reaction in which the nucleus of a heavy atom such as uranium or plutonium is split into two approximately equal parts by a neutron, charged particle, or photon. (12 Dec 1998) |
