effect /ef·fect/ (ĕ-fekt´) the result produced by an action.
Anrep effect abrupt elevation of aortic pressure results in a positive inotropic effect, augmented resistance to outflow in the heart.
Bayliss effect increased perfusion pressure and subsequent stretch of vascular smooth muscle causes muscle contraction and increased resistance, which returns blood flow to normal in spite of the elevated perfusion pressure.
Bohr effect increase of carbon dioxide in blood causes decreased affinity of hemoglobin for oxygen.
Doppler effect the relationship of the apparent frequency of waves, as of sound, light, and radio waves, to the relative motion of the source of the waves and the observer, the frequency increasing as the two approach each other and decreasing as they move apart.
experimenter effects demand characteristics.
Haldane effect increased oxygenation of hemoglobin promotes dissociation of carbon dioxide.
position effect in genetics, the changed effect produced by alteration of the relative positions of various genes on the chromosomes.
pressure effect the sum of the changes that are due to obstruction of tissue drainage by pressure.
side effect a consequence other than that for which an agent is used, especially an adverse effect on another organ system.
Somogyi effect a rebound phenomenon occurring in diabetes: overtreatment with insulin induces hypoglycemia, which initiates the release of epinephrine, ACTH, glucagon, and growth hormone, which stimulate lipolysis, gluconeogenesis, and glycogenolysis, which, in turn, result in a rebound hyperglycemia and ketosis.
Hal·dane effect (hôl d n )n. The promotion of carbon dioxide dissociation that results from the oxygenation of hemoglobin. |
Haldane effect
oxygen loss from hemoglobin makes the hemoglobin more basic and enhances the absorption of CO2.
