| gonadal dysgenesis, mixed | A syndrome of gonadal dysgenesis in which there is a testis on one side and a "streak gonad" on the other. The phenotype is generally male, but may be female since the individual is a mosaic. Various karyotypes have been identified, including 45,xo/47,xyy; 45,xo/46,xy; and 45,xo/46,xyo. (12 Dec 1998) |

| 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 cell leukaemia | Term infrequently used as a designation for granulocytic leukaemia, thereby emphasizing the occurrence of different types of cells in the myeloid series (i.e., neutrophilic, eosinophilic, and basophilic granulocytes), in contrast to the comparatively monotonous pattern observed in lymphocytic and monocytic leukaemia.

| 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.

| 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) |
