OBJECTIVE Activated factor XIII (FXIII) crosslinks fibrin to enhance the mechanical strength of a blood clot and increase its resistance to fibrinolysis. The prevalence of a common variant in the FXIII-A gene (V34L) has been reported to be lower in patients with myocardial infarction and ischemic stroke than in controls, suggesting a protective role for this polymorphism in vascular diseases. T...
OBJECTIVE Factor XIII (FXIII) cross-links fibrin upon activation by thrombin. Activation involves cleavage at residue 37 by thrombin, releasing an activation peptide. A common polymorphism (valine to leucine variant at residue 34, V34L), located in the activation peptide, has been associated with increased activation rates and paradoxically a protective effect in cardiovascular disease. There i...
BACKGROUND AND PURPOSE The identification of genetic and environmental factors that could improve the benefit/risk ratio of thrombolytic therapy in patients with ischemic stroke is crucial. METHODS We studied the role in the efficacy and side-adverse effects of thrombolytic therapy in stroke of 2 factors involved in the structure and stability of fibrin clot: fibrinogen levels and factor XIII...
In the blood coagulation cascade, thrombin cleaves fibrinopeptides A and B from fibrinogen revealing sites for fibrin polymerization that lead to insoluble clot formation. Factor XIII stabilizes this clot by catalyzing the formation of intermolecular cross-links in the fibrin network. Thrombin activates the Factor XIII a(2) dimer by cleaving the Factor XIII activation peptide segment at the Arg...
Intracranial hemorrhage is the third most frequent cause of cerebrovascular disease, but few genetic risk factors have been associated with its development. Recently, it has been reported that some polymorphisms that affect clotting factors increase the risk for thrombosis. However, reports have analyzed the effect of polymorphisms influencing the hemostatic state in bleeding disorders insuffic...
BACKGROUND Acute first-ever ischemic stroke (FIS) is a heterogeneous, polygenic disorder. The contribution of vascular genetic variants as inherited causes of ischemic stroke has remained controversial. AIM To examine the association of genetic variants in vascular factors with the occurrence of FIS. MATERIAL AND METHODS The current research was performed in a group of 39 patients with FIS ...
The relationship between genetic polymorphisms and migraine as a cause of an increased risk of thrombotic disorders development is still debated In this respect, factor V Leiden, factor V (H1299R), prothrombin G20210A, factor XIII (V34L), β-fibrinogen, MTHFR (C677T), MTHFR (A1298C), APO E, PAI-1, HPA-1 and ACE I/D seem to play a determinant role in vascular diseases related to migraine. The pre...
زمینه و هدف: تعدادی از پلی مورفیسمهای ارثی فاکتور های انعقادی با پاتوژنز ترومبوآمبولی وریدی و سایر پیامدهای جانبی آن ارتباط دارد. با توجه به اینکه اطّلاعات محدودی از فراونی این پلی مورفیسمها در جمعیّتهای ایرانی در دست است، لذا این مطالعه با هدف بررسی دو مورد از پلی مورفیسمهای فاکتور 13 یعنی xiiia - v34l و xiiib-h95r در جمعیّت سالم انجام شد. روش بررسی: در این مطالعه مقطعی 150 فرد سالم اهداکن...
BACKGROUND Acute rejection episodes and vascular complications are common after renal transplantation and have negative impact on the long-term patient and graft survival. We investigated whether the risks of acute rejection, thrombosis, infarction and graft loss could be predicted based on the presence of functional polymorphisms in the genes of the coagulation and endothelial inflammation cas...
