Blood Coagulation & Fibrinolysis, 2000
We have used three models to study the process of tissue factor-initiated blood coagulation. These are: synthetic 'plasma' mixtures prepared with the proteins and membranes involved in the reaction and its regulation; mathematical models based on the reaction kinetics, binding constants and stoichiometries of individual procoagulant and inhibitor ...

American Journal of Physiology-Legacy Content, 1962
Blood coagulation systems in cyclostome, elasmobranch, and teleost fish were studied and compared. The plasma of all these fish contained a fibrinogen molecule, capable of being clotted by human thrombin, and a prothrombin molecule, capable of being converted into thrombin which could hydrolyze p-tosyl l-arginine methyl ester. The prothrombin activity

Hemodialysis International, 2001
The endothelium is the principal anti‐thrombotic mechanism, providing a non wettable surface and generating potent vasodilators (nitric oxide and prostacyclin) and clotting inhibitors [thrombomodulin and tissue factor pathway inhibitor (TFPI)]. When the integrity of the endothelium is breached, vasoconstriction occurs through neural and chemical ...

Blood coagulation in glomerulonephritis
International Urology and Nephrology, 1986Different parameters of coagulation were studied in 71 patients with glomerulonephritis. In comparison with normal subjects they had lower platelet counts, lower adhesion index and decreased aggregation, decreased partial thromboplastin time (46.4 per cent of patients), increased reptilase time (47.8 per cent) and other disorders. Plasma fibrin monomer

Blood coagulation screening using a paper-based microfluidic lateral flow device.
Lab on a Chip, 2014A simple approach to the evaluation of blood coagulation using a microfluidic paper-based lateral flow assay (LFA) device for point-of-care (POC) and self-monitoring screening is reported.

Size-dependent effects of nanoparticles on enzymes in the blood coagulation cascade.
Nano letters (Print), 2014Nanoparticles (NPs) are increasingly used in diagnostic and drug delivery. After entering the bloodstream, a protein corona will form around NPs. The size and curvature of NPs is one of the major characteristics affecting the composition of bound protein

Blood Cells, Molecules, and Diseases, 2006
Our research aims to provide quantitatively transparent, biologically realistic descriptions of the processes involved in hemostasis which will permit predictions of the behavior of the coagulation system in normal and pathologic states. We use four models of coagulation: (1) numerical approximations of the tissue factor (Tf) pathway of thrombin ...

Magnetic particle imaging of blood coagulation
, 2014We investigated the feasibility of visualizing blood coagulation using a system for magnetic particle imaging (MPI). A magnetic field-free line is generated using two opposing neodymium magnets and transverse images are reconstructed from the third ...

The kinetics of blood coagulation
The Bulletin of Mathematical Biophysics, 1948The kinetics of the blood coagulation system have been formulated and an expression obtained for the “prothrombin time” in terms of the concentrations of the components of the system. A linear plot of data obtained from plasma dilution curves gives the values of the parameters of the system, and yields a mathematical method of comparing relative ...
