...Koji Taira; Hidekazu Kamitsuji; Chikako Okajima; Yoshihiro Fujimura To elucidate the mechanism of enhanced ristocetin-induced platelet aggregation (RIPA) in steroid-responsive nephrotic syndrome (SRNS), plasma levels of von Willebrand factor antigen (vWF:Ag) and ristocetin cofactor (RCof) were...

..., totally abolished ristocetin-induced von Willebrand factor (vWF) binding to platelets and desialylated vWF binding to platelets at an IgG concentration of 2–8 μg/ml. AP-1 also blocked snake venom botrocetin-induced vWF binding at a similar IgG concentration, whereas OP-Fl had a minimal effect...

... by ristocetin-human factor VIII complex. Heparin appeared to have an inhibitory effect on the above systems similar to that reported on bovine factor VIII-induced platelet aggregation. 17 11 1976 21 12 1976 16 4 2009 © 1977 S. Karger AG, Basel 1977 Copyright / Drug Dosage / Disclaimer...

... time, but factor VIII activity was normal and platelet aggregation by ristocetin was nearly normal. Further studies showed that the patient had a high-molecular-weight factor VIII compound, most of which, however, seemed to be somewhat smaller (less aggregated) than that in normal plasma. © 1974 S...

...A.T.W. Goh; B.G. Firkin Fibrinogen (FG) precipitation by ristocetin is enhanced by lowering the temperature to 4 °C. The precipitate has similar properties to an acquired cryofibrinogen being resolubilised on rewarming to 37 °C, and the process of precipitation and resolubilisation can be repeated...

...Chung-Hsin Ts’ao Human blood platelets prepared from EDTA blood were aggregated by ristocetin without the addition of divalent cations. Platelets obtained from blood anticoagulated with a high concentration of EDTA responded to ristocetin more extensively than those with 1 / 10 the strength of EDTA...

...J. Stibbe; P.M. van der Plas Ristocetin-induced platelet aggregation was increased after exercise in 5 healthy volunteers. It was shown that this was the result of the increase of a plasmatic factor. 30 05 1974 27 08 1974 15 4 2009 Ristocetin Platelet aggregation Factor...

... block shear-induced aggregation in a modified Couette viscometer at shear rates of 1,000 and 4,000 s –1 . On the other hand, MoAb 27A10 had a negligible effect on botrocetin-induced GPIb-vWF binding and is only a poor inhibitor of the ristocetin-dependent interaction. In contrast, MoAb 28E6 did abolish...
