| 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) |
| indirect transmission | <epidemiology> Transmission of a parasite through an indirect life cycle. (05 Dec 1998) |
| transmission | 1. <microbiology, physiology> A passage or transfer, as of a disease from one individual to another or of neutral impulses from one neuron to another. 2. <genetics> The communication of inheritable qualities from parent to offspring (18 Nov 1997) |
| transmission breakpoint | <epidemiology> A critical average worm burden below which the mating frequency is too low to maintain a dioecious parasite species. (05 Dec 1998) |
| transmission electron microscopy | <technique> Those forms of electron microscopy in which electrons are transmitted through the object to be imaged, suffering energy loss by diffraction and to a small extent by absorption. Acronym: TEM (18 Nov 1997) |
| transmission microscope | <instrument, optics> A microscope in which the image-forming rays pass through (are transmitted by) the specimen being observed. Refers to both light and electron microscopes. (05 Aug 1998) |
| transmission threshold | <epidemiology> Occurs for a parasite when the basic reproductive rate Ro is equal to 1. Below this threshold level the disease is unable to maintain itself within the host population. Typically, for directly transmitted parasites there is a transmission threshold for the host population size. (05 Dec 1998) |
| transovarial transmission | Passage of parasites or infective agents from the maternal body to eggs within the ovaries; commonly used to describe certain arthropods, to explain the ability of larvae of the next generation to transmit disease pathogens, as with the infection of larval mites or ticks with rickettsiae or viruses. (05 Mar 2000) |
| transstadial transmission | Passage of a microbial parasite, such as a virus or rickettsia, from one developmental stage (stadium) of the host to its subsequent stage or stages, particularly as seen in mites. See: transovarial transmission. (05 Mar 2000) |
| accelerator factor | <chemical> Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor v accomplishes this by forming a complex with factor xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor v leads to owren's disease. Chemical name: Blood-coagulation factor V (12 Dec 1998) |
| acetate replacement factor | <biochemistry> 1,2 dithiolane 3 valeric acid. Regarded as a coenzyme in the oxoglutarate dehydrogenase complex of the citric acid cycle. Involved generally in oxidative decarboxylations of _ keto acids. A growth factor for some organisms. (18 Nov 1997) |
| adrenal weight factor | A postulated substance of adenohypophysial origin responsible for maintenance of the weight of the adrenal cortex. (05 Mar 2000) |
| adrenocorticotropic releasing factor | Hormone produced by hypothalamus that causes pituitary to secrete adrenocorticotropic hormone. (05 Mar 2000) |
