A Model to Study Articular Cartilage Mechanical and Biological Responses to Sliding Loads.

abstract：:A mathematical model has been developed to investigate previously obtained experimental findings relating to the activation of factor X by surface-bound tissue factor--factor VIIa (TF:VIIa) in a tubular flow reactor. In those experiments, factor X was perfused through a microcapillary tube over a range of flow (shear)...
