von Willebrand factor: at the crossroads of bleeding and thrombosis.
Hemostasis and thrombosis represent two sides of the same coin. Hemostasis maintains blood fluidity in the vascular system while allowing for rapid thrombus formation to prevent excessive hemorrhage after blood vessel injury. Thrombosis is a pathologic extension of the normal hemostatic mechanism, occurring when unwanted clot formation develops in certain pathological situations. The molecular ...
متن کاملPlatelet von Willebrand factor in inherited and acquired bleeding disorders.
The majority of plasma proteins involved in the mechanisms of hemostasis are loosely adsorbed on the platelet surface. A few of them, however, can also be measured in washed platelets, in which they are contained in the intracellular organelles called a granules. The main proteins involved in blood coagulation concentrated in platelets are von Willebrand factor (vWF), fibrinogen, and factor V. ...
متن کاملCut off value of technetium uptake in the differential diagnosis of Graves, disease and subacute thyroiditis
Objective(s):The aim of this study was to determine whether technetium (99mTc) uptake is a relevant method for the differential diagnosis of Graves disease and subacute thyroiditis and calculate its cutoff value in case of its relevancy. Methods: A total of 69 patients, who were followed up (>3 months) in our hospital for thyrotoxi...
متن کاملRisk score to predict gastrointestinal bleeding after acute ischemic stroke
BACKGROUND Gastrointestinal bleeding (GIB) is a common and often serious complication after stroke. Although several risk factors for post-stroke GIB have been identified, no reliable or validated scoring system is currently available to predict GIB after acute stroke in routine clinical practice or clinical trials. In the present study, we aimed to develop and validate a risk model (acute isch...
متن کاملCorrection of bleeding symptoms in von Willebrand factor-deficient mice by liver-expressed von Willebrand factor mutants.
OBJECTIVE von Willebrand Factor (vWF) structure-function relationship has been studied only in vitro. To investigate the physiological importance of particular vWF domains, we have introduced mutations into murine vWF (mvWF) cDNA inhibiting vWF binding to glycoprotein (Gp) Ib, GpIIbIIIa, and to fibrillar collagen. METHODS AND RESULTS We delivered wild-type (WT) or mutant mvWF cDNA into vWF-de...
