Endotoxemia is often associated with extreme inflammatory responses and disseminated intravascular coagulation. Protease-activated receptors (PARs) mediate cellular responses to coagulation proteases, including platelet activation and endothelial cell reactions predicted to promote inflammation. These observations suggested that PAR activation by coagulation proteases generated in the setting o...
background: although stabilization ponds and lagoons are suitable treatment processes due to simplicity of operation and low per capital costs, the effluents of these systems have too high of a total suspended solids concentration to be discharged into receiving waters. this problem is mainly caused by algae. in this study, an electro-coagulation reactor was examined to remove algae from the f...
The objective of this study was to evaluate the effect of temperature-humidity index (THI) on the milk coagulation properties of Holstein-Friesian dairy cattle from northeast part of Italy. A total of 592 individual milk samples from six dairy herds were evaluated. The milk coagulation properties traits analysed were milk rennet coagulation time and curd firmness, as well as the fat, protein, a...
The interaction between cell-surface tissue factor (TF) and the plasma coagulation factor VII (FVII) initiates the coagulation network that leads to the generation of thrombin and the formation of a fibrin clot. Thrombin also activates cellular protease activated receptors (PARs) through which it activates components of the inflammatory pathway. TF is expressed constitutively by cardiomyocytes ...
Vitamin K was discovered early last century at the same time as the vitamin K-antagonists. For many years the role of vitamin K was solely ascribed to coagulation and coagulation was thought to be involved only at the venous blood side. This view has dramatically changed with the discovery of vitamin K-dependent proteins outside the coagulation cascade and the role of coagulation factors at the...
Specific affinity characteristics of the neoplastic paraprotein have been established as exceptional causes of bleeding in patients with malignant gammopathies. We describe a case in which a relationship between impaired coagulation parameters and the concentration of serum paraprotein, without specific affinity for any coagulation protein, could be established. Alternative causes of bleeding w...
Aberrant immune responses represent the underlying cause of central nervous system (CNS) autoimmunity, including multiple sclerosis (MS). Recent evidence implicated the crosstalk between coagulation and immunity in CNS autoimmunity. Here we identify coagulation factor XII (FXII), the initiator of the intrinsic coagulation cascade and the kallikrein-kinin system, as a specific immune cell modula...
Vitamin K-dependent coagulation factors can promote adenoviral cell transduction in vitro. In vivo, warfarin pretreatment ablates liver targeting of an adenovirus serotype 5 (Ad5) vector deleted of CAR binding capability. Here, we assess in vivo transduction and biodistribution of Ad5 vectors with nonmodified fibers (Ad5) and a serotype 47 fiber-pseudotyped Ad5 (Ad5/47; subgroup D) virus follow...
Despite the large number of the outstanding researches, pathogenesis of osteonecrosis remains unknown. During the last decades the hypothesis that increased intravascular coagulation may be the pathogenetic mechanism which leads to osteonecrosis is gaining constantly support. Both primary factors of hyper-coagulability, such as resistance to activated protein C, protein C and protein S deficien...
The use of herbal preparations for staunching blood flow and reducing the risk of vascular thrombosis is common worldwide. In this study, aqueous and methanolic extracts of plants used to treat blood-associated complaints were investigated to determine their effects on red blood cell haemolysis and coagulation. The extent of haemolysis was determined spectrophotometrically. Prothrombin time (PT...
