To study the interrelationships of the major human coagulation pathways, factor X activation in normal and various deficient human plasmas was evaluated when clotting was triggered by dilute rabbit or human thromboplastin. Various dilutions of thromboplastin were added to plasma samples containing 3H-labeled factor X, and the time course of factor X activation was determined. At a 1/250 dilutio...
Data on the anticoagulant power of Uvaria chamae, a plant used in traditional medicine, remain unknown despite its many therapeutic and biological virtues. The present study aimed to compare effects aqueous macerate, ethanolic macerate decoction U. chamae leaves. activity macerated decocted was evaluated vitro against endogenous exogenous coagulation pathways pool displaced normal plasmas. Thes...
Systems biology seeks to provide a quantitative framework to understand blood as a reactive biological fluid whose function is dictated by prevailing haemodynamics, vessel wall characteristics, platelet metabolism, numerous coagulation factors in plasma, and small molecules released during thrombosis. The hierarchical nature of thrombosis requires analysis of adhesive bond dynamics of activated...
Differences in the coagulation and fibrinolytic system of rats fed a fish oil based diet (fish oil diet) and fed a soybean oil based diet (control diet) were determined. Concentrations of plasma lipids were depressed in rats fed the fish oil diet. Prothrombin time (PT) and activated partial thromboplastin time (APTT) of rats fed the fish oil diet were longer than for the rats fed the control di...
Fibrin plays an essential role in hemostasis as both the primary product of the coagulation cascade and the ultimate substrate for fibrinolysis. Fibrinolysis efficiency is greatly influenced by clot structure, fibrinogen isoforms and polymorphisms, the rate of thrombin generation, the reactivity of thrombus-associated cells such as platelets, and the overall biochemical environment. Regulation ...
Heparanase that was cloned from and is abundant in the placenta is implicated in cell invasion, tumor metastasis, and angiogenesis. Recently we have demonstrated that heparanase may also affect the hemostatic system in a non-enzymatic manner. Heparanase was shown to up-regulate tissue factor (TF) expression and interact with tissue factor pathway inhibitor (TFPI) on the cell surface, leading to...
Human factor XI (FXI) is a blood coagulation factor participating in the early phase of the intrinsic pathway of blood coagulation. It circulates in blood as a glycoprotein composed of two identical chains held together by a single disulfide bond between the fourth apple domains. FXI has been expressed in baby hamster kidney (BHK) cells, where it was synthesized as a single-chain molecule that ...
Sequence analysis of a Triatoma dimidiata salivary gland cDNA library resulted in the identification of two transcripts (Td60 and Td101) homologous to triabin, an inhibitor of thrombin in Triatoma pallidipennis saliva. In the present study, a recombinant protein of Td60, designated dimiconin, was expressed in Escherichia coli and its activity was characterized. The resulting protein inhibited t...
conclusions an hb-driven algorithm, in combination with the “coagulation box” and the early use of clotting factors, could be a simple and effective tool for improving coagulopathy in multiple trauma patients. results over a 12-month investigation period, 123 severe multiple trauma patients needing intensive care therapy were admitted to our trauma center (mean age 48 years, mean iss (injury se...
