[Interaction of influenza A and B viruses with a carbon-containing sorbent].

The investigation demonstrated that influenza A and B viruses actively interacted with a sorbent obtained from modified oxygen-containing graphite via hydrothermal treatment irrespective of the antigenic structure of surface proteins. Virionic sorption occurred in a wide range of temperatures from 8 to 34 degrees C for 15 min or more. After interaction with the sorbent, the titer of a virus decreased 4- to 256-fold.

[Nonspecific potential-dependence of conductivity of a membrane, modified by nonselective channel formers with an unlimited number of states].

A formula describing the nonspecific potential-dependent conductance of membranes modified by a channel former with an unlimited number of states was derived. The characteristic features of this potential dependence and their experimental manifestations were analyzed.

[An autoregulation model in the system of squid axonal channels].

A model that describes the interactions in the system of squid axon channels is proposed. The variables of the model are channel concentration and membrane voltage. The model represents the simplest mathematical formulation of the data on axon membrane, its components, and their role in the generation and propagation of action potential.

[Readaptation after total intravenous anesthesia in one-day surgery].

The authors analyze the stages of readaptation and recovery of clear consciousness in the immediate postoperative period in 200 patients administered one of the four variants of intravenous anesthesia in a one-day surgical hospital. The purpose of this work was to optimize the anesthetic care and the readaptation period. The stages of readaptation were assessed by psychophysiological testing.

[Stabilization of a conducting channel in lipid bilayer membranes by an electric field].

A strong transversal electric field is shown to stabilize a macroscopic conducting pore in a lipid membrane. The dependence of the pore radius on the applied voltage is obtained.

[Kalipsol-based balanced intravenous anesthesia in pediatric outpatient dental practice].

Basing on clinical studies of anesthesia in 568 children, central hemodynamic studies, analysis of the blood acid-base balance and gases, glycemia level, and assessment of the psychoneurologic status, the authors validate the usefulness of calypsol-based anesthesia in practical outpatient pedodontics. Such anesthesia did not influence the stability of central hemodynamics parameters, nor did it change the acid-base balance and blood sugar level; it provided an adequate protection of the patient from surgical stress with the adaptation mechanisms remaining intact. The child may leave the clinic 2.

[Interaction of the Embden-Meyerhof pathway and hexose monophosphate shunt in erythrocytes].

A mathematical model of glycolysis in human erythrocytes for the interaction between the Embden-Meyerhof and the pentose phosphate pathways has been developed. The characteristic surfaces, i. e.

[Mathematical model for energy metabolism in erythrocytes. Independence of scaled glycolytic characteristics of individual features of the donors].

A mathematical model for energy metabolism of erythrocytes includes the first three enzymes of the Embden-Meyerhof pathway as well as total ATPase. It was assumed that the ATPase is strongly inhibited by AMP. The model was used to calculate the dependence of the rate of ATP production and glucose consumption on ATP concentration, i.

[Interrelationship between the rate of ATP-consuming processes and ATP concentration in intact erythrocytes].

The behaviour of ATP concentrations in intact erythrocytes upon glucose addition to the erythrocyte suspension at a constant rate was studied. At different rates of glucose addition lower than the rate of glucose consumption at normalcy, the corresponding ATP concentrations are established, which are dependent on the rate of glucose influx. The 20% decrease of ATP concentration from the physiological value is observed at a 2-fold decrease of the flux.
