| 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) |
| perinatal transmission | <microbiology, paediatrics> Transmission of a pathogen, such as HIV, from mother to baby during birth. See: Vertical Transmission. (09 Oct 1997) |
| horizontal transmission | <epidemiology> Transmission occurring generally within a population, but not including vertical transmission. (05 Dec 1998) |
| neurohumoral transmission | A process by which a presynaptic cell, upon excitation, releases a specific chemical agent (a neurotransmitter) to cross a synapse to stimulate or inhibit the postsynaptic cell. Synonym: neurotransmission. (05 Mar 2000) |
| non-direct transmission | <epidemiology> A mode of transmission that differs in some mysterious way from indirect transmission. (05 Dec 1998) |
| synaptic transmission | <physiology> The process of propagating a signal from one cell to another via a synapse. (10 Jan 1998) |
| disease transmission | The transmission of infectious disease or pathogens. When transmission is within the same species, the mode can be horizontal (disease transmission, horizontal) or vertical (disease transmission, vertical). (12 Dec 1998) |
| disease transmission, horizontal | The transmission of infectious disease or pathogens from one individual to another in the same generation. (12 Dec 1998) |
| disease transmission, patient-to-professional | The transmission of infectious disease or pathogens from patients to health professionals or health care workers. It includes transmission via direct or indirect exposure to bacterial, fungal, parasitic, or viral agents. (12 Dec 1998) |
| disease transmission, professional-to-patient | The transmission of infectious disease or pathogens from health professional or health care worker to patients. It includes transmission via direct or indirect exposure to bacterial, fungal, parasitic, or viral agents. (12 Dec 1998) |
| disease transmission, vertical | The transmission of infectious disease or pathogens from one generation to another. It includes transmission in utero or intrapartum by exposure to blood and secretions, and postpartum exposure via breastfeeding. (12 Dec 1998) |
| duplex transmission | The passage of impulses in both directions through a nerve trunk. (05 Mar 2000) |
| iatrogenic transmission | Transmission of infectious agents due to medical interference (e.g., transmission by contaminated needles). (05 Mar 2000) |
