Published in 2018 at "Acta Biotheoretica"

DOI: 10.1007/s10441-018-9329-8

Abstract: This computational study generates a hypothesis for the coagulation protein whose initial concentration greatly influences the course of coagulation. Many clinical malignancies of blood coagulation arise due to abnormal initial concentrations of coagulation factors. Sensitivity… read more here.
