Alterations of the coagulation potential of heparinized blood after using an extracorporeal circulation have been studied by means of a toluidine blue-calcium chloride reagent. This technique was originally used to detect the effect of activation by contact on the coagulation mechanism in heparinized blood. It has been shown that it also detects, in the presence of heparin, the clotpotentiating...

introduction: the main inhibitors of coagulation pathway are antithrombin (at), protein c and protein s. these inhibitors are necessary to prevent thromboembolism. hereditary deficiency of inhibitors is the main cause of alteration in balance between the anti-clotting and the formation of thrombin. patients with this abnormality are susceptible to venous thromboembolism (vte). two major clinica...

background some of the dental procedures can cause bleeding. bleeding control can be difficult in some patients because of systemic disease or chronic anticoagulant therapy, so they may be at increased risk for bleeding occurrences or even death following invasive dental procedures. this study was schemed to measure the knowledge of general dentists in shiraz city regarding coagulation tests pe...

The human melanoma cell line M24met expresses tissue factor, the cellular initiator of the blood coagulation cascade. Blocking of the coagulation pathways at the level of tissue factor, factor Xa, or thrombin inhibits hematogenous M24met metastasis in SCID mice, implicating a role for thrombin generation in this process. Dependent on cell surface tissue factor activity, M24met cells generate th...

Background: Coagulation Factor VII is a vitamin K-dependent serine protease which has a pivotal role in the initiation of the coagulation cascade. The congenital Factor VII deficiency is a recessive hemorrhagic disorder that occurs due to mutations of F7 gene. In the present study C91S (p.C91S) substitution was detected in a patient with FVII deficiency. This mutation has not b...

infection with human immunodeficiency virus (hiv) is a progressive condition which may cause endothelial dysfunction and liver damage leading to coagulopathy. with adventure of highly active antiretroviral therapy (haart), life expectancy has prolonged in hiv positive patients but several acquired immunodeficiency syndrome (aids)-related conditions such as coagulopathies are responsible for ass...

Background Regular exercises decrease the risk of various diseases. This is a reason to recommend exercises for health promotion. Thus American Heart Association (AHA) and American College of Sport Medicine (ACSM) have issued guidelines for young people resistance exercises. Aim: To investigate the effect of resistance training exercise on hematological, immunological and coagulation parameters...

Sickle cell disease (SCD) is associated with a complex vascular pathophysiology that includes activation of coagulation and inflammation. However, the crosstalk between these 2 systems in SCD has not been investigated. Here, we examined the role of tissue factor (TF) in the activation of coagulation and inflammation in 2 different mouse models of SCD (BERK and Townes). Leukocytes isolated from ...
