Following the standard sample preparations and Gram staining, microbial smears were investigated using an automated and computerized analyzer developed by the Mintz Radio Engineering Institute in Moscow. Morphological and tinctorial analysis established significant differences in cell area, perimeter and limit. Significant differences in tinctorial properties of microbial cells make possible image research using the RGB and HSV color spaces. Automated analysis enables identification of microbial cells simultaneously by digital images of morphological and color/brightness parameters. The proposed techniques can be helpful in constructing an electronic microflora atlas of various human biotopes.","PeriodicalId":8683,"journal":{"name":"Aviakosmicheskaia i ekologicheskaia meditsina = Aerospace and environmental medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67958887","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 subjects' age varied between 19 and 27 years. The measured parameters included peak systolic velocity (Vps) and resistive index (RI) of the popliteal (PA) and superficial femoral (SFA) arteries in the right leg, and common carotid artery (CCA) before, during and after testing. Results of the investigation evidenced that static strain in leg muscles during the test causes constriction in a segment distal from the superficial femoral artery confirmed by decreased Vps and increased RI in SFA and increased Vps and stable RI in PA. Under the head-to-pelvis g-loads, the static muscle strain is liable to impede blood pooling in leg muscles. Decreases of CCA Vps and RI due to the static muscle strain in consequence of, probably, vasodilatation in the brain, will be favorable to blood redistribution toward the head at the time of g-load. There was no reliable difference in doppler US data between the Vietnamese and Russian pilots.","PeriodicalId":8683,"journal":{"name":"Aviakosmicheskaia i ekologicheskaia meditsina = Aerospace and environmental medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67959907","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}

Subject of our investigation was structural transformations in the adrenals and thymus as a result of systematic exposure to gravitational overloads (GOL), and arginine glutamate as a corrigent agent. Light and electron microscopy techniques were used to explore morphological changes in the adrenals and thymus of 24 adult male Wistar rats with the initial body mass of 260–280 g. Over the period of 45 days, the rats were daily exposed to 10-minute rotation at 9 G with and without injection of 4 % arginine glutamate solution as an antioxidant and membrane stabilizer. It was established that systematic exposure to extreme GOL produces serous changes in the structural and functional organization of both organs such as obvious hemodynamic disorders and degenerative structural effects in all cell populations. The extent of structural changes attests to adaptation failure and development of irreversible damages. The experiment showed that prolonged injection of arginine glutamate failed to abate these morphofunctional disorders in the adrenals and thymus and to enhance adaptive potential during the systematic rotation at extreme GOL.","PeriodicalId":8683,"journal":{"name":"Aviakosmicheskaia i ekologicheskaia meditsina = Aerospace and environmental medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135838736","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}

Cell senescence induced by oxidative stress can alter the MSCs morphofunctional characteristics. The work was aimed at studying the senescence-related morphofunctional changes in adipose-derived MSCs (AD-MSCs) under sublethal oxidative stress. Viability of cells in 96 hours after adding 500 µМ H2O2 made up less than 5 % (incubation time – 6 hrs.). Percentage of survived cells in other samples was higher (> 85 %); however, the rate of cell growth decreased significantly. Treated AD-MSCs were increased in size and cytoplasm was more granular. Active senescence-associated β-galactosidase was detected in nearly 100 % cells. These findings are evidence of activation of senescence. The level of intracellular reactive oxygen species (ROS) was increased, as well as the activity of lysosomal and mitochondrial compartments. After the one-hour oxidative stress, ROS returned to baseline values. Increase in endogenous ROS was observed in 24–96 hrs. post the stress.","PeriodicalId":8683,"journal":{"name":"Aviakosmicheskaia i ekologicheskaia meditsina = Aerospace and environmental medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135800934","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}
