| humoral | <physiology> Of, relating to, proceeding from or involving a bodily humour now often used of endocrine factors as opposed to neural or somatic. (18 Nov 1997) |
|---|---|
| humoral antibodies | <immunology> Antibodies which are secreted by B lymphocytes circulating in the blood, in response to antigens found in body fluids. (06 Mar 1998) |
| humoral doctrine | The ancient Greek theory of the four body humors (blood, yellow and black bile, and phlegm) that determined health and disease. The humors were associated with the four elements (air, fire, earth, and water), which in turn corresponded to a pair of the qualities (hot, cold, dry, and moist). A proper and evenly balanced mixture of the humors was characteristic of health of body and mind; an imperfect balance resulted in disease. Temperament of body or mind also was supposed to be determined, e.g., sanguine (blood), choleric (yellow bile), melancholic (black bile), or phlegmatic (phlegm). Synonym: fluidism, humoralism, humorism. (05 Mar 2000) |
| humoral immune response | <immunology> Those immune responses mediated by antibody. (06 Mar 1998) |
| humoral immunity | <immunology> A form of immunity whereby B lymphocytes and plasma cells produce antibodies to foreign agents (antigens) and stimulate T lymphocytes to attack them (cellular immunity). These antibodies also stimulate the release of chemical mediators (for example interferon, complement) which enhance antigen destruction. (06 Mar 1998) |
| humoral pathology | The thesis that disorders in the fluids of the body, especially the blood, are the basic factors in disease. (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) |
| perinatal transmission | <microbiology, paediatrics> Transmission of a pathogen, such as HIV, from mother to baby during birth. See: Vertical Transmission. (09 Oct 1997) |
| 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) |
