They are producers of bioactive compounds (phenolics, polysaccharides, proteins, steroids, terpenoids, etc.) possessing around 130 therapeutic effects (antimicrobial, anti-inflammatory, antioxidant, immunomodulatory, etc.). Mushrooms are also reported as potential neurotrophic and neuroprotective agents. Seventeen edible and inedible agaricomycetous species from different taxonomic and ecological groups have been reported in Armenia to possess neuroprotective activity. Evaluation resource value and biotechnological potential of Armenian agaricomycetous mushrooms will assist further development of novel myco-pharmaceuticals to prevent and mitigate different disorders, including neurodegenerative.","PeriodicalId":20692,"journal":{"name":"Proceedings of the YSU B: Chemical and Biological Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86299100","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}

It is shown that the use of essential oil of cloves contributes to the alignment of shifts in the level of functional indicators of students, by increasing the adaptive capacity of the organism. Essential oil of cloves causes a decrease of “physiological cost” of physical activity performed by students by strengthening the economization processes of functional systems activity. Curing an increase in the sympathetic effects on the body, induced by physical activity, the oil of cloves contributes to the rapid restoration of the functional state of the body in the nearest post-load period. As a control, indicators of the functional state and cardiac hemodynamics of students who, during bicycle ergometer load, were not subjected to the corrective influence of the essential oil of cloves, were used.","PeriodicalId":20692,"journal":{"name":"Proceedings of the YSU B: Chemical and Biological Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79955432","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}
