| positive | Having a value greater than zero, indicating existence or presence of a condition, organism, etc. As chromatin positive or Wassermann positive, characterised by affirmation or cooperation. Origin: L. Positivus (18 Nov 1997) |
| positive accommodation | The increased refractivity of the eye that occurs when shifting from the distance to a near object. (05 Mar 2000) |
| positive afterimage | An afterimage in which the lightness relationship is the same as the original one; if chromatic, it appears in the same colour. (05 Mar 2000) |
| positive afterpotential | A spontaneous or inducible increase in transmembrane potential of a cardiac or nerve cell following the completion of repolarization. In the heart, this usually corresponds to the electrocardiographic U wave. (05 Mar 2000) |
| positive anergy | A reduction of the normal or usual immunologic response resulting from a reaction to a specific allergen. Synonym: specific anergy. (05 Mar 2000) |
| positive control | Mechanism for gene regulation that requires that a regulatory protein must interact with some region of the gene before transcription can be activated. (18 Nov 1997) |
| positive convergence | Inward deviation of the visual axes even when convergence is at rest, as in cases of convergent squint. (05 Mar 2000) |
| positive cooperativity | Cooperativity in which successive ligand molecules appear to bind with increasing affinity. (05 Mar 2000) |
| positive electrode | <microscopy> The electrode to which a major flow of electrons takes place internally (as in a cathode-ray tube) or to which an external positive voltage supply is connected. (05 Aug 1998) |
