    Abstract The human immunodeficiency virus (HIV) is currently one of the most pressing global health problems. Since its discovery in 1978, HIV has claimed the lives of more than 35 million people, and the number of people infected today reaches 37 million. In the absence of highly active antiretroviral therapy (HAART), HIV infection is characterized by a steady decrease in the number of CD4+ T-lymphocytes, but its manifestations can affect the central nervous, cardiovascular, digestive, endocrine and genitourinary systems. At the same time, complications induced by representatives of pathogenic and opportunistic microflora, which can lead to the development of bacterial, fungal and viral concomitant infections, are of particular danger. It should be borne in mind that an important problem is the emergence of viruses resistant to standard therapy, as well as the toxicity of the drugs themselves for the body. In the context of this review, of particular interest is the assessment of the prospects for the creation and clinical use of drugs based on small interfering RNAs aimed at suppressing the reproduction of HIV, taking into account the experience of similar studies conducted earlier. RNA interference is a cascade of regulatory reactions in eukaryotic cells, which results in the degradation of foreign messenger RNA. The development of drugs based on the mechanism of RNA interference will overcome the problem of viral resistance. Along with this, this technology makes it possible to quickly respond to outbreaks of new viral diseases.

    Abstract Introduction: Influenza is one of the most pressing global health problems. Despite the wide range of available anti-influenza drugs, the viral drug resistance is an increasing concern and requires the search for new approaches to overcome it. A promising solution is the development of drugs with action that is based on the inhibition of the activity of cellular genes through RNA interference.
    Aim: Evaluation in vivo of the preventive potential of miRNAs directed to the cellular genes FLT4, Nup98 and Nup205 against influenza infection.
    Materials and methods: The A/California/7/09 strain of influenza virus (H1N1) and BALB/c mice were used in the study. The administration of siRNA and experimental infection of animals were performed intranasally. The results of the experiment were analyzed using molecular genetic and virological methods.
    Results: The use of siRNA complexes Nup98.1 and Nup205.1 led to a significant decrease in viral reproduction and concentration of viral RNA on the 3rd day after infection. When two siRNA complexes (Nup98.1 and Nup205.1) were administered simultaneously, a significant decrease in viral titer and concentration of viral RNA was also noted compared with the control groups.
    Conclusions: The use of siRNAs in vivo can lead to an antiviral effect when the activity of single or several cellular genes is suppressed. The results indicate that the use of siRNAs targeting the cellular genes whose expression products are involved in viral reproduction is one of the promising methods for the prevention and treatment of not only influenza, but also other respiratory infections.

    Titelübersetzung Liver blood flow during xenon anesthesia in surgical hepatology.
    Abstract The authors present their experience gained in anesthesias for resection of the liver. Methods for evaluating total liver blood flow by ueveredine dilution, portal blood flow by thermodilution, changes in arterial blood supply during and after the operation are discussed. Effects of methods of anesthesia on total liver blood flow and some parameters of systemic hemodynamics are analyzed. Effects of neuroleptanalgesia, ketamine and xenon anesthesia on liver blood flow are compared. The efficiencies of anesthesias for resection of the liver and their effects on liver function during and after the operation are evaluated. The results evidence that disorders in liver circulation parameters were far less pronounced in the patients operated on under Xe anesthesia in comparison with patients operated on under neuroleptanalgesia and calypsol anesthesia. The study confirmed a pronounced analgesic effect of xenon, and clinical results confirmed that Xe anesthesia can be used in traumatic interventions.

    Abstract Spectra of amplitudes of polarization of erythrocytes, yeast cells, and latex particles in the range of 1-10 Hz were investigated by the method of dielectrophoresis. Positive dielectrophoresis of erythrocytes and yeast cells the frequency range of 60 - 100 Hz was revealed. The theoretically positive dielectrophoresis was evidenced by the occurrence of channels across the cell membrane and bacterial cell wall.

    Titelübersetzung The role of precipitating serum antibodies in tuberculosis patients.
    Abstract The content of serum alpha 1-proteinase inhibitors (alpha 1-PI), alpha 2-macroglobulins, transferrins, albumin, immunoglobulins A, M and G and C3- and C4-complement factors was investigated in a group of patients (n = 35) with pulmonary tuberculosis who showed precipitating antituberculous circulating antibodies having the properties of autoantibodies. A direct relationship between the available circulating antibodies cross-reacting with the tissues and the rate of an extrapulmonary localization of tuberculous process in pulmonary tuberculosis patients, on the one hand, and their inverse relationship to the level of blood alpha 1-PI, on the other, were revealed. It is recommended to define cross-reacting antibodies and alpha 1-PI concentration to predict the risk of extrapulmonary foci of a tuberculous inflammation.
