Investigations of the effects of phitochemical compounds from extracts of pomegranate, grape seeds and garlic on expression of NFE2L2, JUN, SOD1 in cultivated cells of the human blood showed that transcription of SOD1 increased in the presence of pomegranate and grape seed extracts. Level of mRNA in NFE2L2 and JUN rose briskly only under the influence of a high concentration of the grape seed extract. Level of JUN mRNA correlated with NFE2L2 mRNA. Garlic extract had no effect on transcription of NFE2L2, JUN, SOD1. Activation of the transcription of all 3 genes under study by the grape seeds extract can contribute to controlling the free radical processes in human cells.

The literary review encompasses the experimental and clinical evidence of the potency of Russian medicaments nicotinoyl gamma-aminobutyric acid (picamilon), hydroxyzine nicotinoyl glutamate calcium (ampasse), and combineddrug cytoflavin containing nicotinic acid and its derivatives in extreme conditions. Analysis shows that these medicaments and nicotinic acid derivatives protect tangibly from acute and chronic hypoxia of varying genesis, hypo- and hyperthermia, hypokinesia etc. To increase potency and safety of medical care after exposure to extreme factors the search for other nicotinic acid derivatives should be furthered.

Chromatography-mass spectrometry of dried blood spots sampled during the year-long wintering of the 65th Russian expedition to the Antarctic station Vostok identified 6798 peptides. The maximal confidence level made possible the classification of 1239 proteins. Named were proteins that changed concentrations by months 4 and 12 of wintering. Crude proteins typical for these periods were identified, too. Methods of bioinformatics established period-specific as well as common changes in proteins on the level of confidentiality. The proteomic data allow discussion of signaling pathways and ways the organism adapts to extreme life environments. Our results suggest that professional activities in the conditions of long-term hypobaric hypoxia, isolation and hypokinesia on Antarctic station «Vostok» are accompanied by changes in the blood proteome affecting first and foremost the processes that control chemical and energy homeostasis on the molecular, cell, tissue, organ and system levels.

Investigation with participation of the first- to fourth-year female students of the flight school in Krasnodar had the purpose to ascertain that sizes of the present pilot gear fit modern types of the female body. It was found out that sizes of many female students are below minimal ranges of the pilot gear fit. The quantity of these female students varies from 11 % (anti-g suits) to 100 % (O2 masks). The group of female students was actually representative of the women of the same age in this country. We conclude that the existing misses' sizes do not fit the anthropometric parameters of female candidates for flight training. To sum up, there is need to revise the size ranges of the flight gear with consideration of modern types of the female body.

The paper reports the results of measuring absorbed doses and quality factor of ionizing space radiation in the ISS Service module in June-October of 2020 with the use of dosimeter Tritel as part of space experiment Matreshka-R. Mean dose rate over the period amounted to 0.38 ± 0.03 mGy/d. Experimental data on the dose rate dynamics allow to set aside contributions of Earth's radiation belts and galactic cosmic radiation in the total daily dose. The daily average quality factors made up 3.05 ± 0.16 for total dose, 1.6 ± 0.1 for Earth's radiation belts and 5.1 ± 0.3 for galactic space radiation.

Expression of inborn immunity genes was studied in 10 essentially healthy male subjects aged 24 to 32 years in a 21-day dry immersion experiment without countermeasures. To evaluate the humoral immunity function, genes encoding Toll-like receptors, proteins mediating NF-kB, AP-1, Akt, TLR4; apoptosis proteins, and CLEC4E, HSPD1, PTGS2 were selected. Fenol-cloroform extraction was used to obtain total RNA from peripheral blood monocytes CD14+. Subsequently, total RNA was reverse transcribed to generate cDNA for real-time PCR. The results showed substantial changes in expression of these genes suggesting that changes in the TLRs function on the transcriptional level were at the very start of the immune response to 21-d DI.

We validated an approach to optimization of the higher plant illumination system within a biotechnical life support system (BTLSS) in order to reduce power consumption and equivalent harvest mass. The challenge was to stabilize oxygen concentration in the air of a pressurized compartment. To compare different approaches to power consumption optimization, we used publications on a study in which BTLSS with a 27 m2 cultivation area provided leaf vegetables (Chinese cabbage) to 2 human subjects. Time course of the daily energy and O2 consumption was divided into 5 periods according to specified levels of loading. In context of a Moon mission scenario, the optimal photon flux density and white-red light ratios were calculated using regression models for each day between vegetation days 8 and 14. Experimentally obtained models of photosynthetic productivity were used to calculate a daily lighting level required to produce oxygen in the amount sufficient for the crew. It was shown that this method of O2 stabilization makes possible, within 7 days, power consumption reduction by 68 % and increase of the coefficient of light energy consumption by harvest in 2.3 times as compared to the control growing under continuous invariable illumination. Moreover, equivalent mass of the illumination system reduced 30 % as compared to the control.

This is an overview of the current knowledge of the structural and functional organization of the smooth muscle tissue (SMT) presenting equally fundamental and applied interest for space biomedicine. SMT is a structural component of the visceral organs involved in adaptive reactions or pathological developments. According to the evidence, cell populations of visceral SMT contain smooth myocites differing in histophysiological properties. Many investigators reason that the SMT morphological and embriological origin is organ-specific and can be an area of translational researches, including space biomedicine. In spite of the multisided analysis of animal and humans tissues exposed to the spaceflight factors, no effort has been made to study SMT in space microgravity or ground-based modeling experiments. However, space gastroenterology knows facts about morphological transformations in the digestive organs in the spaceflight environment. Clearly, SMT as a structural component of the gastrointestinal tract may contribute directly in a number of organ-specific changes during orbital missions. SMT studies will unveil mechanisms of adaptive cell, and molecular changes with stromal mediation due to microgravity, and reveal targets for enhancing health control in space missions.

The paper presents the results of experiments with 48-hour horizontal and vertical clinostatting of 5-day old Arabidopsis thaliana seedlings in 2 types of lighting, i.e. white light (4000 cd) and lateral blue light (450 nm). The experiments were performed in a clinostat designed to install Petri dishes with juvenile Arabidopsis thaliana in the horizontal and rotate it about the horizontal axis at a speed of 1 rev/min. Angular bend of the main root (MR) was measured as it elongated. It was demonstrated that, on the average, vertical clinostating in white light caused a more significant MR departure from the apical-basis axis than the horizontal clinostating. The proposed space experiments with Arabidopsis seedlings and laboratory controls will require extensive preliminary studies of the effects of specific light spectra and directions, and crop orientation. In blue light, there was no difference in the MR departure due to the seedlings placement in the clinostat; however, more than 75 % of the seedlings tended to bend away from the light source. Directed blue lighting in a 2D-clinostat can be an approach to root system orientation based on the negative phototropism.

Interrelation between amplitude and frequency of the α- and β- brain waves, heart rate variability (HRV) and hemodynamics was studied in 65 hypertensive patients (level 2) and compared to 75 healthy people. Methods of the investigations included EEG, 24-hour Holter monitoring, echo-cardiography, blood pressure measurement and HRV calculation. In patients, α and β parameters decreased by 27 to 35 %, respectively. In comparison to normal people, reductions of α and β amplitudes as well as powers made up 20%, 30 % and 16–45 %, respectively. Total HRV in patients decreased 60 %. Interrelations between the α- and β- waves, HRV and hemodynamics were numerous and multidirectional in patients, whereas in normal people they were weak or absent at all. The results evidence interrelations between the cerebral bioelectrical activity, sympathetic heart rate regulation and hemodynamics in hypertensive patients living in a midaltitude region.

Methods of the investigations included EEG, 24-hour Holter monitoring, echo-cardiography, blood pressure measurement and HRV calculation. In patients, α and β parameters decreased by 27 to 35 %, respectively. In comparison to normal people, reductions of α and β amplitudes as well as powers made up 20%, 30 % and 16–45 %, respectively. Total HRV in patients decreased 60 %. Interrelations between the α- and β- waves, HRV and hemodynamics were numerous and multidirectional in patients, whereas in normal people they were weak or absent at all. The results evidence interrelations between the cerebral bioelectrical activity, sympathetic heart rate regulation and hemodynamics in hypertensive patients living in a midaltitude region.","PeriodicalId":8683,"journal":{"name":"Aviakosmicheskaia i ekologicheskaia meditsina = Aerospace and environmental medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67953062","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}
