Cleavage of blood coagulation factor XIII and fibrinogen by thrombin during in vitro clotting.
Thrombin cleavage of blood coagulation Factor XIII (a2b2) and fibrinogen was studied during in vitro clotting to determine the physiologic sequence of these events. First, the time course of fibrin formation and cleavage of Factor XIII was measured in platelet-rich plasma. Cleavage of fibrinogen was measured by using a radioimmunoassay for fibrinopeptide A. Conversion of trace amounts of radioi...
متن کاملImpaired Activity of Blood Coagulant Factor XIII in Patients with Necrotizing Enterocolitis
Necrotizing enterocolitis (NEC) is the most common gastrointestinal (GI) medical/surgical emergency of the newborn and a leading cause of preterm neonate morbidity and mortality. NEC is a challenge to diagnose since it often shares similar clinical features with neonatal sepsis. In the present study, plasma protein profiling was compared among NEC, sepsis and control cohorts using gel electroph...
متن کاملPseudothrombocytopenia Caused by Platelet Agglutinins That Are Reactive in Blood
The phenomenon of in vitro platelet clumping and consequent pseudothrombocytopenia in the presence of EDTA was studied in the plasmas and sera of three patients. A heterogeneity was identified among these platelet agglutinins. lgG agglutinins present in two patients recognized antigens that were present when EDTA was added to platelets. This effect of EDTA did not appear to be mediated by calci...
متن کاملFibrinogen and factor XIII A-subunit genotypes interactively influence C-reactive protein levels during inflammation.
OBJECTIVE Fibrinogen is a target of autoimmune reactions in rheumatoid arthritis (RA). Fibrin(ogen) derivatives are involved in inflammatory processes and the generation of a stable fibrin network is necessary for sufficient inflammation control. As the density and stability of fibrin networks depend on complex interactions between factor XIIIA (F13A) and fibrinogen genotypes, the authors studi...
متن کاملThe assembly of nonadhesive fibrinogen matrices depends on the αC regions of the fibrinogen molecule.
Adsorption of fibrinogen on fibrin clots and other surfaces strongly reduces integrin-mediated adhesion of platelets and leukocytes with implications for the surface-mediated control of thrombus growth and blood compatibility of biomaterials. The underlying mechanism of this process is surface-induced aggregation of fibrinogen, resulting in the assembly of a nanoscale multilayered matrix. The m...
