The article discusses the reasoning associated with the change in the trajectory of the Russian budgetary policy in the current cycle and the substantiation of the forecast values of the main macroeconomic indicators used in the formation of the federal budget. The characteristics and analysis of the dynamics of the volumes of income and expenses are presented. The main theoretical concepts aimed at finding the optimal amount of debt financing for economic growth and the size of public debt are considered.

Anti-influenza drugs and vaccines have a limited effect due to the high mutation rate of virus genome. The direct impact on the conservative virus genome regions should significantly improve therapeutic effectiveness. The RNA interference mechanism (RNAi) is one of the modern approaches used to solve this problem.

Article Synopsis
  • The paper investigates the complete nucleotide sequence of a cryptic plasmid (pTP33) found in the Yersinia pestis strain I-2638, linked to the plague.
  • It utilized the 454 GS Junior sequencing platform to assemble 1,855 nucleotide reads into a continuous stretch of 33,978 base pairs with a GC content of 50.25%.
  • The analysis identified 56 open reading frames, including proteins related to toxin-antitoxin systems and DNA metabolism, revealing similarities with phage-related proteins from specific insect endosymbionts.

The allele polymorphism of the housekeeping genes (dnaE, lap, recA, pgm, gyrB, cat, chi, gmd) from the Vibrio cholerae strains with different epidemic importance (n = 41) isolated in Siberia and at the Far East during the cholera pandemic VII was tested. All toxigenic strains isolated at the period of epidemic complications irrespective of time and source of isolation were characterized by the identical allele profile and belonged to the same sequence-type. Nine sequence types were detected in non-epidemic isolates.

Numerous studies showed that a new technology for the clinical microbiology laboratories, Matrix-Assisted Laser Desorption Ionization--Time of Flight Mass Spectrometry (MALDI-ToF MS), allows fast, accurate, and effective identification of most clinically relevant microorganisms to be implemented. In the present review, we discuss applications of this approach for identification and typing of extremely dangerous pathogens--Yersinia pestis, Vibrio cholera, and Francisella tularensis, including the advantages and disadvantages of the method, sample preparation and biosafety problems.
