Thrombin (Factor IIa) (EC 3.4.21.5, fibrose, thrombase, thrombofort, topical, thrombin-C, tropostasin, activated blood-coagulation factor II, E thrombin, beta-thrombin, gamma-thrombin) is a serine protease, that converts fibrinogen into strands of insoluble fibrin, as well as catalyzing many other coagulation-related reactions.
Pender's health promotion model theory was first published in 1982 and later revised in 1996 and 2002. It is used for nursing research, education, and practice. Research has been conducted on the model since its inception. 250 articles have been published in the English language that use or apply Pender's HPM. [ 6 ]
Prothrombin G20210A is a genotypic trait that provides a prompter coagulation response. It increases the risk of blood clots including from deep vein thrombosis , and of pulmonary embolism . [ 1 ] One copy of the mutation increases the risk of a blood clot from 1 in 1,000 per year to 2.5 in 1,000. [ 1 ]
Coagulation activation markers are biomarkers of net activation of coagulation and fibrinolysis. [ 1 ] [ 2 ] Examples include prothrombin fragment 1+2 (F1+2), thrombin–antithrombin complex (TAT), fibrinopeptide A (FpA), fibrin monomers (FMs), plasmin-α 2 -antiplasmin complex (PAP), activated protein C–protein C inhibitor (APC-PCI), and D ...
The division of coagulation in two pathways is arbitrary, originating from laboratory tests in which clotting times were measured either after the clotting was initiated by glass, the intrinsic pathway; or clotting was initiated by thromboplastin (a mix of tissue factor and phospholipids), the extrinsic pathway.
The normal clotting process depends on the interplay of various proteins in the blood. Coagulopathy may be caused by reduced levels or absence of blood-clotting proteins, known as clotting factors or coagulation factors. Genetic disorders, such as hemophilia and Von Willebrand disease, can cause a reduction in clotting factors. [2]
By Raphael Satter. WASHINGTON (Reuters) - A senior U.S. official who is among those working to evict alleged Chinese hackers from American telecom companies has a word of advice for his fellow ...
Proteinase-activated receptor 1 (PAR1) also known as protease-activated receptor 1, coagulation factor II receptor and thrombin receptor is a protein that in humans is encoded by the F2R gene. [5] PAR1 is a G protein-coupled receptor and one of four protease-activated receptors involved in the regulation of thrombotic response.
