Increased shear stress- and ristocetin-induced binding of von Willebrand factor to platelets in cord compared with adult plasma.
Multiple indications do exist that the extensive neonatal platelet adhesion and aggregation, and the shorter closure time of neonatal compared with adult whole blood in the platelet function analyzer 100 are attributable to the physiological high plasma concentrations and high concentrations of unusually large von Willebrand factor (vWf) multimers in neonates. However, to date the direct experi...
متن کاملInteraction of platelet plasma membranes with thrombin-activated platelets.
This study described the binding of platelet plasma membranes to either control or thrombin-activated platelets. Glycoproteins in plasma membranes isolated from human platelets were labeled by oxidation with periodate followed by reduction with [3H]NaBH4. Labeled membranes were incubated with either control or thrombin-activated platelets. The amount of membranes bound was measured by separatin...
متن کاملActivated factor V is a cofactor for the activation of factor XI by thrombin in plasma.
The mechanism by which the intrinsic pathway of coagulation contributes to physiological hemostasis is enigmatic. Thrombin activates factor XI, a key zymogen in this pathway, which leads to increased thrombin generation. As thrombin-dependent activation of factor XI in vitro is relatively inefficient, we hypothesized that a physiological cofactor supports this reaction in a plasma environment. ...
متن کاملBovine Thrombin and Activated Factor X
Parke-Davis bovine thrombin was resolved into three distinct protein peaks on a Sephadex G-200 column. A stepwise chromatographic technique on diethylaminoethyl (DEAE) cellulose was developed for the complete separation and partial purification of thrombin and activated Factor X. Thrombin was quantitatively eluted in the first protein peak with 0.1 M NaCl, pH 7.0. A second peak with residual th...
متن کاملDesign and Fabrication of Plasma Array Antenna with Beam Forming
In this paper, the design and implementation of plasma antenna array with beam forming is discussed. The structure consists of a circular array of plasma tube enclosed in a unipolar UHF band monopole antenna. Beam forming is possible by stimulated plasma tubes. The combination of the above antenna with plasma excitation controller makes a beam forming smart antenna. An experimental model in UHF...
