Publication activity (preparation and printing of informational articles, booklets, books, etc.) makes it possible to acquaint a wide range of readers with the achievements of space biology and medicine. A significant amount of work is carried out on the organization of exhibitions (both innovative technologies and museum and educational). The Institute pays much attention to the formation of educational content and lecture activities. An important area is the development of cooperation with public organizations in the field of cosmonautics. The Institute widely uses not only traditional and customary methods in this work, but also develops and applies new approaches, technological and methodological techniques.","PeriodicalId":8683,"journal":{"name":"Aviakosmicheskaia i ekologicheskaia meditsina = Aerospace and environmental medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67951570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analyzed were structures of 4 LSS designs including supply-relied, hybrid, semi-closed and two options of nearly closed LSS by the criterion of failure classifications: all failures are independent and common cause failures are probable. An adequate level of robustness must be first reached using an integral approach that is inclusion of supplies, finalizing the system design and production, and inherent cold redundancy of critical regeneration subsystems. This must be followed by informal analysis of alternative LSS designs with rational values of the other 4 Q-factors. It was concluded that simple, reliable and cheap supply-based LSS as well as hybrid LSS are uneconomic for exploration class missions, as their insertion masses exceed the acceptable level in 5 times and twice, respectively. Nearly closed LSS is also unacceptable for the reason of very high R&D costs. Therefore, we give preference to partly closed LSS, provided the requirement to increase the LSS specific weight from 0.15 to 0.28 is satisfied.","PeriodicalId":8683,"journal":{"name":"Aviakosmicheskaia i ekologicheskaia meditsina = Aerospace and environmental medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67955027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Classic visual EEG analysis revealed characteristic and individual changes in the brain bioelectrical activity. Spectral analysis provided information about relative powers (RP) of the EEG bands: delta-2 (2–4 Hz), tetha (4–8 Hz), alpha (8–13 Hz) and beta-1 (13–24 Hz) in 19 leads total. The body of RP changes made it possible to trace dynamics of the brain functional response to different g-loads. The greatest tetha RP decay (up to 15.5 %) with the simultaneous beta RP rise up to 8.4 % at 2.92 g pointed to activation of the cortex of cerebral hemispheres due to attenuation of the inhibitory effect of the nonspecific brain system. The neurophysiological individual typological patterns and absence of alpha RP changes implied a reasonably good CNS adaptation to all SAHC g-loads.","PeriodicalId":8683,"journal":{"name":"Aviakosmicheskaia i ekologicheskaia meditsina = Aerospace and environmental medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67954032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Changes in the gene expression due to microgravity can lead to degradation of fertility; however, the mechanism that triggers these changes is not fully understood. In our investigation we determined mRNA levels in the prime cytoskeletal proteins and analyzed histone methylation and acetylation activities in Drosophila melanogaster ovaries during 79-hr microgravity modeled with the use of a random positioning machine (RPM), and per os introduction of essential phospholipids. The results showed that the fruit flies exposure to modeled microgravity over the entire oogenesis cycle increased levels of mRNA genes encoding the cytoskeletal proteins in oocytes and that this can be, probably, associated with increased acetylation of the histone H3 Lys9 and Lys27. Essential phospholipids seem to prevent growth and/or initiate mRNA reductions in the majority of cytoskeleton elements in the flies exposed to modeled microgravity; however, the tubulin and lamin B binding proteins increased in the respective controls. Essential phospholipids leveled histone 3 Lys9 acetylation in modeled microgravity but enhanced Lys27 acetylation in the control.","PeriodicalId":8683,"journal":{"name":"Aviakosmicheskaia i ekologicheskaia meditsina = Aerospace and environmental medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67949908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper attempts to define which of these factors determined the human body stress-reaction and energy metabolism. Venous plasma samples were periodically gathered for analysis from 16 members of the 13th Soviet Antarctic expedition to the station Vostok in 1968. Members of the expedition were divided into 2 groups. One group was experimental, i.e. intermittently consumed anti-asthenia amino acid and vitamin supplements and psychoactive drugs, and the other was the placebo control. The investigation showed that in the course of the year-long existence in the extreme environment the averaged levels of 11-oxicorticosteroids and adrenergic compounds were elevated while the noradrenergic levels were at the bottom margins of their normal ranges. Averaged values of blood glucose and total cholesterol were well within the range of normal variations.

The polymers and AAs were tested for solubility in various solvents in order to choose those that would be suitable for preparation of simultaneous polymer/AA solutions and ensuing films. Differential scanning calorimetry and IR spectroscopy were used to determine morphology and structure of SKEP/AA and PVB/AA compositions. Since SKEP does not blend with AAs, these compositions are two-phase systems. In contrast, PVB/AA compositions represent monophase systems. PVB compatibility with AAs is explained by establishment of hydrogen bonds. Both types of composition exhibit film-forming properties. SKEP/AA films are characterized by low rigidity, whereas PVB/AA films demonstrate high rigidity. Both types of composition inhibit growth of mold fungi.","PeriodicalId":8683,"journal":{"name":"Aviakosmicheskaia i ekologicheskaia meditsina = Aerospace and environmental medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67952886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
