Factor XIII is one of the twelve coagulation factors and also known as a fibrin-stabilizing factor. In 2012, we encountered a male RA patient with hemorrhagic factor XIII deficiency who had been treated with tocilizumab for two years. There are few reports regarding the relationship between tocilizumab (a humanized monoclonal antibody against the interleukin-6 receptor (IL-6R)) and factor XIII....

Type XIII collagen belongs to the group of transmembrane collagens. In this thesis the plasma membrane localisation and function of type XIII collagen have been studied using cell biological methods. Type XIII collagen was found to reside in focal adhesions. It appeared in these structures at a very early stage of their assembly and disappeared from them concurrently with focal adhesion protein...

Factor XIII (Fibrin-stabilizing factor) is a tetrameric structural pro-transglutaminase from the transglutaminase family. Factor XIII activity is associated with the structure of fibrin clot. Factor XIII turns into XIII-A, which is an active transglutaminase, in the result phase of coagulation cascade together with Ca and thrombin activation. The main aim of Factor XIIIA is to connect ε(δ-gluta...

In this paper, we present a new class of public key cryptosystems by modifying K(XII)SE(1)PKC [1], referred to as K(XIII)SE(1)PKC, and a particular class of K(XIII)SE(1)PKC, Kp(XIII)SE(1)PKC. We show that K(XIII)SE(1)PKC would improve both the coding rate and the security, compared with K(XII)SE(1)PKC. We also show that Kp(XIII)SE(1)PKC realizes the coding rate of exactly 1.0. In a sharp contra...

conclusions the case was fully investigated and diagnosed as a case with factor xiii deficiency causing such uncontrolled bleeding after extraction of a tooth. introduction factor xiii deficiency is a relatively rare hereditary bleeding disorder, which is usually found during infancy or early childhood. this condition may involve both genders within different races in an equal manner. its incid...

The binding of plasma factor XIII to fibrinogen or fibrin that has been chemically or enzymatically induced to polymerize was studied. Factor XIII binding was assayed using a 3H-putrescine incorporation assay and an 125I-plasma factor XIII binding assay. More than 80% of the native and radiolabeled plasma factor XIII was bound to fibrin I formed by reptilase in EDTA, citrate, or heparin anticoa...

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...
