Effect of mechanical strain on solute diffusion in human TMJ discs: an electrical conductivity study.

abstract：:A kinetic model based on first principles, for β(2)-microglobulin, is presented to obtain precise parameter estimates for individual patient. To reduce the model complexity, the number of model parameters was reduced using a priori identifiability analysis. The model validity was confirmed with the clinical data of te...
