Selective introduction of Cu impurity into fine-dispersed ZnS obtained during the process of one-stage synthesis.

Fine ZnS:Cu, obtained by method of self-propagating high-temperature synthesis was investigated. As flux in the mixture NaCl was used, Zn and S were taken in stoichiometric ratio; Cu concentration in charge consisted ~1.5 wt.

Effects of fullerene C60 nanocomposites on human platelet aggregation.

The effects of fullerene C(60) nanocomposites on human platelet aggregation induced by ADP, ristocetin, and collagen were studied. The nanocomposite containing fullerene C(60) in polyvinyl pyrrolidone solution did not change platelet aggregation, while fullerene C(60) in crown ether and Twin-80 solutions inhibited ADP-induced platelet aggregation by 20 and 30%, respectively.

[The mass transfer of blood plasma components across the erythrocyte plasmalemma in a centrifugal force field].

In mammals, nucleus-free erythrocytes participate in two types of movement: a forward and a rotatory motion. The latter type brings about a centrifugal force in the red blood cells. This induces distortion of the erythrocytes, a diffusion speed of the blood components, and an unspecific sorption.

[Changes in cytospectrophotometric characteristics and configuration of erythrocytes exposed to constant electric current].

The action of constant current (0.01-3 A, 1-25 V) on human blood during varying exposures induced intensified plaque-formation in the preparations of the local hemolysis test, and transformation of red blood cells-discocytes into echino- and poikilocytes that was attended by pronounced changes in the extent, intensity of light diffusion, natural green and red luminescence of red blood cells caused by flavoproteins and metalloporphyrins. The growth of the last factor has evidenced the presence of significant destructive changes in the cells as a result of constant current direct action on red blood cells.
