Heritability of Clot Formation, Morphology, and Lysis
Objective—The relative balance between clot formation and fibrinolysis is considered to reflect thrombotic potential following vascular injury. The aims of the present study were to (1) to determine the contribution of genetic and environmental factors to variance in measures of clot structure/function in the Leeds Family Study, and (2) to determine the relationship between measures of clot str...
متن کاملSynthetic Hormones in Animal Husbandry
Introduction: There are three synthetic hormones approved by the U.S. Food and Drug Administration (U.S. FDA) for growth promotion in cattle and sheep raised for meat production: the estrogenic compound zeranol, the anabolic steroid trenbolone acetate (TBA), and the progestin melengestrol acetate (MGA). The FDA approves and regulates the use of hormone implants, establishing tolerance levels (m...
متن کاملGamma globulin inhibition of fibrin clot formation.
Myeloma gamma globulins have been reported to interfere with fibrinogen-fibrin conversion. A patient with multiple myeloma is described with a gamma globulin IgG1lambda concentration of 11 g per dl, prolonged thrombin time and poor clot retraction. Purified gamma globulin from the patient's serum and from normal serum caused prolongation of the thrombin time and reptilase clotting time assays i...
متن کاملClot formation by group A streptococci.
Group A streptococci of several different M serotypes can cause human plasma to clot in nutrient-poor media. Addition of glucose to the medium prevents clot formation. Once formed, clots are stable for several days and can be lysed on addition of exogenous streptokinase or urokinase. Clot lysis can also be achieved by addition of glucose to a clot containing wild-type group A streptococci but n...
متن کاملZinc promotes clot stability by accelerating clot formation and modifying fibrin structure.
Zinc released from activated platelets binds fibrin(ogen) and attenuates fibrinolysis. Although zinc also affects clot formation, the mechanism and consequences are poorly understood. To address these gaps, the effect of zinc on clot formation and structure was examined in the absence or presence of factor (F) XIII. Zinc accelerated a) plasma clotting by 1.4-fold, b) fibrinogen clotting by 3.5-...
