HFRS Morbidity Rates in the Territory of the Republic of Mordovia in 2009-2012

In the territory of Mordovia registered have been 321 cases of HFRS infection over the period of 2009-2012. Following the pattern of dynamics as regards HFRS epidemiological process, one can observe lingering tendency to the increment in morbidity rates, associated with the enhancement of quality and efficacy of clinical and laboratory diagnostics of the disease, as well as with activation of natural HFRS foci in the territory of Mordovia. Analysis of the gender-age structure of HFRS incidence has revealed that most liable to the infection is active, employable population, 20 to 50 years old. Morbidity rates for the male strata of the population are three times higher than for female. Epidemiological peculiarities of HFRS morbidity, characteristic of the Republic of Mordovia, are as follows: recurrence of epidemiological upsurge, autumn-winter seasonality, predominance of urban dwellers cohort and household route of infection

Training of Specialized Teams of Center of Hygiene and Epidemiology in the Republic of Mordovia

The competition was held in conditions that imitated emergency situations of different origin. All stages of the competition were more complicated than those of the first one, two new stages were included in the program, radio transceivers were used to provide interactions in the group

SANCTIONS: POLITICAL AND ECONOMIC FORESHORTENING

A number of aspects of the change of the political and economic relations, apparent by the sanctions policy of the western states to the Russian Federation and its realization, has been considered. The balance between the liberty, equality and fraternity, the perfect competition and free business, on the one hand, and the competition of smothering, ball and chain, on the other hand, – has been disclosed. It has been substantiated, that the western states seek to substitute the colonial influence in the past for sanctions pressure in our days. It allows them to get not only the competitive advantage, but also to obtain the absolute dictatorship sometimes. The conclusion has been made, that external intervention in the natural course of managing and especially the rough administrative influence never gives a positive effect

Invasive mosquito species Aedes albopictus and Aedes aegypti on the Black Sea coast of the Caucasus: genetics (COI, ITS2), Wolbachia and Dirofilaria infections

The area of invasive species Aedes albopictus and Aedes aegypti is expanding. Precise identification and understanding of the genetic diversity of invasive mosquito populations allows us to develop appropriate control methods. Endosymbiotic bacterium Wolbachia pipientis has different effects on their arthropod hosts and can influence the transmission and spread of the pathogens. The objective of the presented study was molecular-genetic identification of the Aedes mosquitoes collected in sampling sites on the Black Sea coast from 2007 to 2017; determination of genetic variability of Ae. aegypti, Ae. albopictus and their symbiotic bacteria Wolbachia; assessment of mosquitoes ability to be infected and to spread parasitic Dirofilaria. Another objective was obtaining the genetic characteristic of laboratory strain Ae. aegypti IMPITM. We investigated two markers of nuclear and mitochondrial DNA from Ae. albopictus and Ae. aegypti and compared them to DNA from Ae. cretinus and Ae. koreiсus sympatrically inhabiting the territory, as well as to one of Ae. aegypti from a laboratory line. The study of nuclear and mitochondrial DNA revealed a low level of variability in the invasive mosquitoes Ae. albopictus and Ae. aegypti collected at different collection sites and in different years. More than a half of Ae. albopictus were infected with Wolbachia, two strains of bacteria, wAlbA and wAlbB, occur in the Ae. albopictus population on the Black Sea coast. Total infection of Ae. aegypti and Ae. albopictus with dirofilariae was 1.8 %. Dirofilaria immitis was found only in mosquito abdomen, larvae of infective stage L3 were not found. D. repens larvae developed to the infective stage in the mosquitoes of both species

Изучение эффектов магния оротата на модели первично-генерализованных судорог у крыс

The effect of magnesium orotate on the model of primary generalized convulsions in the experiment was studied. The course of administration of magnesium orotate (preparation Magneter) at a dose of 0,06 g / kg of weight reduces the severity and duration of seizures caused by thiosemicarbazide, increases the survival of animals, has a neuroprotective effect, affecting various morphological structures. The drug Magnerot - the donor of magnesium, replenishing in the body the deficit caused by the convulsant.Исследовано действие магния оротата на модели первично-генерализованных судорог в эксперименте. Курсовое введение магния оротата (препарат Магнерот) в дозе 0,06 г/кг массы тела уменьшает тяжесть и длительность судорог, вызванных тиосемикарбазидом, увеличивает выживаемость животных, оказывает нейропротективный эффект, влияя на различные морфологические структуры. Препарат Магнерот - донатор магния, восполняющий в организме дефицит, вызванный конвульсантом

Способ получения рекомбинантных антител, продуцируемых клеточной линией, трансдуцированной рекомбинантными аденовирусами

Objectives. To develop a technology for obtaining recombinant antibodies in a suspension culture of human HEK293 cells using transduction with recombinant adenovirus serotype 5 (rAd5) carrying genes expressing heavy and light chains of antibodies on the example of two broadspectrum anti-influenza antibodies 27F3 and CR9114.Methods. Ad5-27F3-H, Ad5-CR9114-H, and Ad5-27F3-L recombinant adenoviruses carrying the 27F3 antibody heavy chain gene, CR9114 antibody heavy chain gene, and 27F3 light chain gene, respectively, were generated using the AdEasy™ Adenoviral vector system. To accumulate preparative amounts of recombinant r27F3 and rCR9114 antibodies, the HEK293 suspension cell line was transduced with recombinant adenoviruses carrying genes for heavy and light chains of antibodies. The cells were cultured in a wave-type bioreactor. Chromatography was used to purify recombinant antibodies from the culture medium. After analyzing the molecular weights of purified antibodies using protein electrophoresis, their ability to interact with influenza A and B viruses was analyzed using the Western blot technique, while their ability to neutralize influenza A and B viruses was evaluated using the virus neutralization assay.Results. A method for the accumulation and purification of recombinant r27F3 and CR9114 antibodies from the culture medium of a suspension culture of human cells following transduction with its recombinant adenoviruses carrying the genes for heavy and light chains of these antibodies was developed. The ability of the r27F3 antibody to interact with and neutralize influenza A viruses of group 1 (except influenza A virus subtype H2) and group 2 was shown. The ability of the rCR9114 antibody to interact with influenza A viruses of group 1 and influenza B viruses, as well as to neutralize influenza A viruses of group 1, was demonstrated.Conclusions. A technology for obtaining recombinant antibodies in a suspension culture of HEK293 cells using transduction with recombinant adenoviruses carrying genes expressing heavy and light chains of antibodies was developed along with a confirmation of their specificity.Цели.
