mismatch

Informatics
See Language mismatch, Logic mismatch.
 
Molecular biology
A defect in the pairing of two complementary DNA sequences where a base in one strand differs from that expected (according to complementarity) with the other.
 
Neurophysiology
A ratio of neurotransmitter to neuroreceptor that differs from the expected 1:1.
 
For example, high concentrations of neuroreceptors for substance P are found in the neocortex and hippocampus, even though the neurotransmitters themselves are in low concentrations. The mismatch phenomenon implies the presence of another system(s) of cell communication, which may have a role in non-synaptic interaction among cells.
 
Pulmonology
A marked difference between ventilation (V) and perfusion (Q) on a V/Q scan, a finding typical of pulmonary embolism.
