Front Dynamics in an Activator-Inhibitor System of Equations

2017
We consider the construction of formal asymptotic approximation for solution of the singularly perturbed boundary value problem of an activator-inhibitor type with a solution in a form of moving front. Corresponding asymptotic analysis provides a priori information about the localization of the transition point for moving front that is further used for

Disturbances in the tissue plasminogen activator/plasminogen activator inhibitor (TPA/PAI) system in systemic lupus erythematosus

American Journal of Hematology, 1991
AbstractIncreased thrombogenesis observed in systemic lupus erythematosus (SLE) is derived from multiple mechanisms, including: Enhanced coagulation factor VIII:VWf activity, lupus anticoagulants, anti‐phospholipid antibodies, acquired deficiencies of natural anti‐thrombotic mechanisms (protein C, protein S, anti‐thrombin III), and impaired ...

The plasminogen activator inhibitor system in bone cell function.

Clinical orthopaedics and related research, 1995
The plasminogen activator (PA)/plasmin pathway has been implicated in a variety of physiologic and pathologic processes that require tissue remodeling and cell motility. The pathway is highly regulated and results in the generation of the broad spectrum serine protease, plasmin, from the zymogen plasminogen.

Pattern formation in a (2 + 1)-species activator-inhibitor-immobilizer system

Physica A: Statistical Mechanics and its Applications, 1992
Abstract The necessary and sufficient conditions for a Turing instability in a (2 + 1)-component reaction-diffusion system are derived. The 2-component subsystem consists of an arbitrary activator-inhibitor system in which the activator and the inhibitor diffuse at identical rates.

Fibrinolytic system of vascular endothelial cells. Role of plasminogen activator inhibitors.

Haemostasis, 1989
The regulation of the fibrinolytic system is of critical importance during hemostasis, wound repair, neoplasia, inflammation, and a variety of other biologic processes. This control is achieved in a large part through the action of specific plasminogen activator inhibitors (PAIs).
