| mixed agglutination | Immune agglutination in which the aggregates contain cells of two different kinds but with common antigenic determinants; when used to identify isoantigens, the test cells are exposed to appropriate isoantibody, washed, and then mixed with indicator erythrocytes that combine with free sites on the test cell-attached isoantibody. Synonym: mixed agglutination. (05 Mar 2000) |

| mixed agglutination reaction | Immune agglutination in which the aggregates contain cells of two different kinds but with common antigenic determinants; when used to identify isoantigens, the test cells are exposed to appropriate isoantibody, washed, and then mixed with indicator erythrocytes that combine with free sites on the test cell-attached isoantibody. Synonym: mixed agglutination. (05 Mar 2000) |
| mixed aphasia | In which all aspects of speech and communication are severely impaired. at best, patients can understand or speak only a few words or phrases; they cannot read or write. Synonym: mixed aphasia, total aphasia. (05 Mar 2000) |
| mixed astigmatism | Astigmatism in which one meridian is hyperopic while the one at right angle to it is myopic. (05 Mar 2000) |
| mixed beat | A beat triggered by more than a single electrical impulse, when the wave fronts coincide to act together on a single final pathway of activity; in the electrocardiogram, the atrial or ventricular complex when either atria or ventricles are activated jointly by two simultaneous or nearly simultaneous invading impulses. Synonym: combination beat, mixed beat, summation beat. (05 Mar 2000) |
| mixed chancre | A sore resulting from simultaneous inoculation of a site with syphilis and chancroid. (05 Mar 2000) |
| mixed connective tissue disease | <syndrome> A syndrome with overlapping clinical features of systemic lupus erythematosus, scleroderma, polymyositis, and Raynaud's phenomenon. The disease is differentially characterised by high serum titres of antibodies to ribonuclease-sensitive extractable (saline soluble) nuclear antigen (nuclear ribonucleoprotein) and a speckled epidermal nuclear staining pattern on direct immunofluorescence. A more modern term for this condition is the undifferentiated connective tissues disease. (22 Sep 2002) |
| mixed dentition | <dentistry> The situation when both deciduous and permanent teeth are present. (08 Jan 1998) |
| mixed discrete-continuous random variable | <statistics> A random variable that may assume some values with probabilities and others with probability densities. For example, in a 35-year-old man with familial polyposis of the colon, the distribution of time until malignant disease occurs consists of a probability that he already has cancer (which would be assigned the waiting time 0), a probability density of developing it in the future and a probability that he will die of some other cause before he develops cancer. (05 Mar 2000) |
| mixed disulfide | <chemistry> Disulfide which is not symmetric on both sides of the -s-s- linkage; e.g., the disulfide formed between coenzyme A and glutathione or between cysteine and coenzyme A or glutathione. Synonym: asymmetric disulfide. (05 Mar 2000) |
| mixed esotropia | <ophthalmology> That type of esotropia in which both accommodative and nonaccommodative factors are present. (05 Mar 2000) |
| mixed expired gas | <physiology> One or more complete breaths of expired gas coming thoroughly mixed from the dead space and the alveoli. (05 Mar 2000) |
| mixed function oxidases | <enzyme> Catalyse the insertion of one oxygen atom of molecular oxygen into the organ substrate. Require a second substrate to donate electrons for the reduction of the second atom in the oxygen molecule to water. Registry number: EC 1.13.12. (12 Dec 1998) |
| mixed gland | A gland that contains both serous and mucous secretory units, a gland that is both exocrine and endocrine, e.g., the pancreas. (05 Mar 2000) |
