It has recently been reported that the polycation Polybrene (hexadimethrine bromide), like ristocetin, agglutinates platelets more extensively in the presence of normal plasma than von Willebrand plasma. Since we have previously proposed that ristocetin may initiate agglutination by reducing platelet surface charge, I investigated the correlation between Polybrene's ability to induce agglutinat...

Erythrocytes aggregation takes places under low shear conditions or at stasis. All suggested mechanisms of erythrocytes aggregation indicated the importance role of fibrinogen and other blood proteins in enhanced erythrocyte aggregation. Recently a special attention is given to the cellular factors that may effect on erythrocytes aggregation. The present study inferred the effect of the cellula...

The biased reptation theory has been applied to the pulsed-field electrophoresis of DNA in agarose gels. A computer simulation of the theoretical model that calculates the mobility of large DNA molecules as a function of agarose pore size, DNA chain properties, and electric field conditions has been used to generate mobility curves for DNA molecules in the size range of the larger yeast chromos...

There is a pressing need for information on the mobility of nanoparticles in the complex aqueous matrices found in realistic environmental conditions. We dispersed three different metal oxide nanoparticles (TiO2, ZnO and CeO2) in samples taken from eight different aqueous media associated with seawater, lagoon,river,andgroundwater,andmeasuredtheirelectrophoretic mobility, state of aggregation, ...

The fourth component of human complement (C4) in 102 individual plasma samples has been examined by the technique of antigen-antibody crossed electrophoresis (AACE). Electrophoretic heterogeneity of C4 was manifested by the repeated occurrence of seven different precipitin patterns. These patterns were formed by varying combinations of three subtypes of C4, differing in electrophoretic mobility...
