[Some aspects of the radiation exposure of cosmonauts traversing the Earth's magnetosphere.]
Aviakosm Ekolog Med. 2021;55(3):51-56. Russian.
Note: From the abstract: "Dose loading of cosmonaut's representative body organs beyond the Earth's magnetosphere was calculated for various scenarios of departure from a reference orbit in space vehicles of different design. Calculation of contribution to the equivalent doses from protons and electrons of Earth's radiations belts and galactic cosmic rays (GCR) demonstrated that, irrespective of vehicle design, during solar minimum and growing activity the equivalent dose does not exceed the established limit for a single exposure to 150 mSv. However, radiation exposure may vary at times depending on the traverse trajectory."

[Investigations of microflora from professional test-subjects and volunteers for isolation studies of up to 20 days in duration.]
Aviakosm Ekolog Med. 2021;55(3):57-61. Russian.
Note: From the abstract: "Microbiocenosis in the upper respiration tracts and intestine was investigated in experienced test-subjects who could, possibly, have adapted to stresses during chamber studies of 8 to 10 days in duration faster than first-timers. The eubiotic index was used to assess positive and negative shifts in microbiota. The intestinal microflora in experienced subjects turned out to be more plastic and adapted much faster compared to the inexperienced counterparts. In both groups, the microbiota composition was compromised slightly at the end of acute adaptation and then stabilized."
