A mathematical model of flow-mediated coagulation identifies factor V as a modifier of thrombin generation in hemophilia A

Hemophilia A is a bleeding disorder categorized as severe, mild, and moderate deficiencies in factor VIII (FVIII). Within these categories the variance in bleeding severity is significant and the origins unknown. The number of parameters that could modify bleeding are so numerous that experimental approaches are not feasible for considering all possible combinations. Consequently, we turn to a mathematical model of coagulation under flow to act as a screening tool to identify parameters that are...

A local and global sensitivity analysis of a mathematical model of coagulation and platelet deposition under flow

Kathryn Link, Michael Stobb, Jorge Di Paola, Keith Neeves, Aaron Fogelson, Suzanne Sindi & Karin Leiderman
The hemostatic response involves blood coagulation and platelet aggregation to stop blood loss from an injured blood vessel. The complexity of these processes make it difficult to intuit the overall hemostatic response without quantitative methods. Mathematical models aim to address this challenge but are often accompanied by numerous parameters choices and thus need to be analyzed for sensitivity to such choices. Here we use local and global sensitivity analyses to study a model of coagulation...

Assessing the impact of product inhibition in a chromogenic assay

Michael Stobb, Karin Leiderman, Suzanne Sindi & Dougald Monroe
Chromogenic substrates (CS) are synthetic substrates used to monitor the activity of a target enzyme. It has been reported that some CSs display competitive product inhibition with their target enzyme. Thus, in assays where enzyme activity is continuously monitored over long periods of time, the product inhibition may significantly interfere with the reactions being monitored. Despite this knowledge, it is rare for CSs to be directly incorporated into mathematical models that simulate these assays. This...
