| perinatal transmission | <microbiology, paediatrics> Transmission of a pathogen, such as HIV, from mother to baby during birth. See: Vertical Transmission. (09 Oct 1997) |
|---|---|
| perinatal | <paediatrics> Pertaining to or occurring in the period shortly before and after birth, variously defined as beginning with completion of the twentieth to twenty eighth week of gestation and ending 7 to 28 days after birth. Origin: L. Natus = born (18 Nov 1997) |
| perinatal care | The care and management of the foetus and newborn infant in the perinatal period before, during, and after delivery. (12 Dec 1998) |
| perinatal death | An inclusive term referring to both stillborn infants and neonatal death's. (05 Mar 2000) |
| perinatal medicine | The branch of medicine dealing with the foetus and infant during the perinatal period. The perinatal period begins with the twenty-eighth week of gestation and ends twenty-eight days after birth. (12 Dec 1998) |
| perinatal mortality | Mortality around the time of birth, conventionally limited to the period from 28 weeks gestation to one week postnatal. (05 Mar 2000) |
| perinatal mortality rate | The number of stillborn infants of 24 completed weeks or more plus the number of deaths occurring under 7 days of life divided by the number of stillborn infants of 24 weeks or more gestation plus all liveborn infants in the same population, regardless of the period of gestation. (05 Mar 2000) |
| perinatal torsion | Tends to be extravaginal type. (05 Mar 2000) |
| magnetically insulated transmission line | <radiobiology> Used to transport power efficiently in vacuum lines at very high power densities. Although the cathode is a space-charge limited electron emitter, the electron flow is confined by self-generated or applied magnetic fields. MITL's are used extensively in light-ion-driven inertial confinement fusion. (09 Oct 1997) |
| vertical transmission | <microbiology> Transmission of a pathogen such as HIV from mother to foetus or baby during pregnancy or birth. See: perinatal transmission. (09 Oct 1997) |
| mass action transmission | <epidemiology> Transmission of infection which occurs at a rate directly proportional to the number or density of both susceptibles and infecteds present. Some authors reserve the name mass action for transmission processes of the form b X Y/N , which we associate with STD-type transmission, and describe transmission rates of the form b X Y , as pseudo-mass action ; the two are equivalent if the population size is unchanging. (05 Dec 1998) |
| microscopy, electron, scanning transmission | A type of electron microscopy which scans with an extremely narrow beam that is transmitted through the sample. The detection apparatus produces an image whose brightness depends on the atomic number of the sample. It should not be confused with microscopy, electron scanning nor with microscopy, electron, transmission (see microscopy, electron). (12 Dec 1998) |
| Conventional Transmission Electron Microscopy | <technique> A term applied to 'normal' transmission electron microscopy imaging. The electron beam is passed through a thin film sample (typically ~1-200 nm thick). Bright field diffraction contrast images are formed with the direct (undiffracted) beam. Dark field images are formed with a selected diffracted beam. CTEM imaging is used in the general observation of samples and careful selection of the diffracting conditions of the sample will allow the analysis of defect structures within the sample. (05 Aug 1998) |
| scanning transmission electron microscopy | <procedure> Method of electron microscopy in which image formation depends upon analysis of the pattern of energies of electrons that pass through the specimen. Has comparable resolving power to conventional transmission EM. (18 Nov 1997) |
| horizontal transmission | <epidemiology> Transmission occurring generally within a population, but not including vertical transmission. (05 Dec 1998) |
