Recognition of functional partners is a pivotal factor in the regulation protein interactions. The areas direct contact between complementary molecules that interact according to Koshland’s "key - lock" scheme deserve special attention. relevance study this kind interactions obvious. In case simplest serine proteinases increased affinity enzyme certain area target ensured by synchronous interac...

We have studied the contribution of platelets to the coagulation of plasma and the effects of activation or inhibition of platelets on the coagulation process in unanticoagulated fresh whole blood (subsequently termed native blood). For this purpose, we have used a free oscillation rheometer (FOR), the ReoRox4, a new instrument that enables noninvasive viscoelastic measurements of clot formatio...

objective(s):  titanium oxides are known to be appropriate hemocompatible materials which are suggested as coatings for blood-contacting devices. little is known about the influence of nanometric crystal structure, layer thickness, and semiconducting characteristics of tio2 on blood hemostasis.   materials and methods: having used sol-gel dip coating method in this study, tio2 thin films were d...

Background: Blood group plays a vital role in the field of transfusion medicine. The relationship between bleeding time, clotting time, and blood group is important in certain clinical conditions such as epistaxis, surgery, and thrombosis. Researchers have shown that epistaxis is more often encountered in patients having blood group O probably due to lower expression of von Willebrand factor, a...
