| Pasteur | Louis, French chemist and bacteriologist. Lived: 1822-1895. See: Pasteur vaccine, Pasteur's effect, Pasteur pipette. (05 Mar 2000) |

| Pasteur effect | <biochemistry> Decrease in the rate of carbohydrate breakdown that occurs in yeast and other cells when switched from anaerobic to aerobic conditions. Results from a relatively slow flux of material through the biochemical pathways of respiration compared with those of fermentation. (18 Nov 1997) |
| Pasteur, Louis | <person> A French chemist and biologist who founded the field of bacteriology and developed the germ theory. He also invented pasteurisation and created the first vaccines against anthrax and rabies. Lived: 1822-1895. (09 Oct 1997) |
| Pasteur pipette | A cotton-plugged, glass tube drawn out to a fine tip, used for the sterile transfer of small volumes of fluid. (05 Mar 2000) |
| Pasteur's effect | The inhibition of fermentation by oxygen, first observed by Pasteur; either not observed, or only slightly observed, in malignant tumours. Compare: Crabtree effect. (05 Mar 2000) |
| Pasteur vaccine | An inactivated virus vaccine, used for preexposure immunization to persons at high risk of exposure, e.g., veterinarians, and in conjunction with rabies immunoglobulin, for postexposure prophylaxis. The official preparation is human diploid cell vaccine produced from rabies virus grown in cultures of human diploid embryo lung cells and inactivated with propriolactone. It has a much lower incidence of adverse reactions than the previously used duck embryo vaccine. (12 Dec 1998) |
| Abbe theory of image formation | <optics, physics> Abbe's theory is based on the fact that a non-self-luminous particle, which is illuminated by an extraneous source, gives rise to diffracted light rays, in addition to the dioptric pencil. He stated that to form a good microscopical image as many of the diffracted rays as possible should be intercepted by the objective. With closely ruled lines, his theory is easily demonstrated by observing the back lens of the objective, for here the diffracted rays can be observed directly if the aperture diaphragm is closed. It can be shown that, when the illumination is arranged to exclude the diffracted images, resolution is lost. (11 Mar 1998) |
| adsorption theory of narcosis | That a drug becomes concentrated at the surface of the cell as a result of adsorption, and thus alters permeability and metabolism. (05 Mar 2000) |
| Altmann's theory | A theory that protoplasm consists of granular particles (called bioblasts) that are clustered and enclosed in indifferent matter. (05 Mar 2000) |
| Arrhenius-Madsen theory | That the reaction of an antigen with its antibody is a reversible reaction, the equilibrium being determined according to the law of mass action by the concentrations of the reacting substances. (05 Mar 2000) |
| atomic theory | That chemical compounds are formed by the union of atoms in certain definite proportions; in its modern form, first advanced in 1803 by John Dalton. (05 Mar 2000) |
| Baeyer's theory | That carbon bonds are set at fixed angles (109 |
| balance theory | In social psychology, a theory which assumes that steady and unsteady states can be specified for cognitive units, such as an individual and his or her attitudes or acts, and that such units tend to seek steady states (balance); e.g., balance exists when both parts of a unit are evaluated the same, but disequilibrium arises when both parts are not evaluated the same, which causes either cognitive reevaluation of the parts or their segregation. See: cognitive dissonance theory, consistency principle. (05 Mar 2000) |
| beta-oxidation-condensation theory | <biochemistry> That the two carbon fragments split from the fatty acid molecule by beta-oxidation are converted to acetic acid and then condensed to acetoacetic acid. (05 Mar 2000) |
| Bohr's theory | That spectrum lines are produced 1) by the quantised emission of radiant energy when electrons drop from an orbit of a higher to one of a lower energy level, or 2) by absorption of radiation when an electron rises from a lower to a higher energy level. (05 Mar 2000) |
