He was born near the small town Darwell in Scotland. He studied at St. Mary’s Hospital Medical School and received his master’s and bachelor’s degrees from London University. The research of the young scientist began with the study of the etiology, diagnosis and vaccine therapy of infectious diseases, he soon began working on finding treatment options for patients with bacterial infections with a talented military doctor Almroth Wright. Working in the Royal Military Medical Service during the First World War, A. Wright and O. Fleming showed that the use of antiseptics after injury does not destroy bacterial pathogens effectively. After the war, O. Fleming made an extremely important discovery of a lytic enzyme with a pronounced antibacterial effect - lysozyme. This discovery prompted him to search for antibacterial drugs actively. In 1928, Alexander Fleming discovered the first antibiotic – penicillin. He found that penicillin is an effective antibacterial substance that can affect pyogenic cocci and diphtheria bacilli. The widespread introduction of penicillin into clinical practice has saved hundreds millions of lives. \u0000Keywords: penicillin, lysozyme, antibiotics, bacterial infections.","PeriodicalId":12181,"journal":{"name":"Faktori eksperimental'noi evolucii organizmiv","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84234293","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}

Investigate the effect of auxins of exogenous origin in nutrient medium in vitro on the germination and organogenesis intensity in Linum usitatissimum L. convar. elongatum (‘Hlinum’ variety) at the constant concentration of 6-benzylaminopurine (BAP). Methods. Hypocotyl segments were cultured on Murashige and Skoog nutrient medium supplemented with sucrose (30 g/l) and phytohormones at various concentrations. Other conditions: photoperiod 16 hours, relative humidity 60–80%, air temperature 22–24°C. Results. Common flax has a great capacity to form callus and shoots under the effect of the following factors: 1) only auxins, 2) only cytokines, 3) combinations of auxins and cytokines. Somatic embryogenesis is also possible on a nonhormonal nutrient medium. Conclusions. For somatic embryogenesis in vitro, the optimal concentrations of BAP can be expressed as 1.0 ≤ BAP ≤ 1.75, the optimal concentrations of BAP for the medium supplemented with 1-naphthylacetic (NAA, 0.05 mg/l) 0.5 ≤ BAP ≤ 2.0, the optimal concentration of NAA for the medium supplemented with BAP (1.0 mg/l) 0.025 ≤ NAA ≤ 0.150, and the optimal concentrations of indol-3-acetics acid (IAA) for the medium supplemented with BAP (1.0 mg/l) 0.05 ≤ IAA ≤ 0.50. \u0000Keywords: Linum usitatissimum L., in vitro, phytohormones, callus, organogenesis.","PeriodicalId":12181,"journal":{"name":"Faktori eksperimental'noi evolucii organizmiv","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91169186","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 aim of the study was to characterize the population distribution of psychiatric phenotypes according to anxiety and depression. Methods. The level of anxiety and depression was assessed with the HADS Hospital Anxiety and Depression Scale test. Students in grades 9-11 of secondary schools in Kharkiv, as well as their parents, were tested. We tested 306 persons from 115 families. Results. The frequency of depression among men in the Kharkiv population is 9%, among women 11%, among boys 15%, among girls 22%; the frequency of increased anxiety among men is 14%, among women 22%, among boys 19%, among girls 44%. There is a positive relationship between anxiety and depression in older men and women, expressed by the association coefficient in men rDT =0.45, in women rDT =0.79. The relatives revealed a similarity in psychological types, described by the association index for depression in mother/daughter pairs r = 0.40, mother/son r = 0.03, father/daughter r = 0.20, father/son r = 0.40; for anxiety: mother/daughter r = 0.15, mother/son r = 0.05, father/daughter r = 0.24, father/son r = 0.01. Conclusions. Individuals of the younger generation are more likely to have signs of anxiety and depression than those of their parents' generation.

Study of the dynamics Gentiana lutea L. plant growth processes in vitro depending on the light regime changes of their cultivation in order to develop a scheme to increase their adaptive potential. Methods. Methods of plant cultivation in vitro, biometric method, as well as ANOVA variance analysis and middle group analysis in pairs using the Tukey test (Tukey test) were used. Results. It is shown that the cultivation of G. lutea plants in vitro using 25 W/m2 light flux intensity in the region of photosynthetically active radiation and the ratio of blue (Eb): green (Eg): red (Er) ranges = 41.8%: 42.7 %: 15.5% triggers non-specific photomorphogenesis reactions for intact plants, which lead to poor root system development, stem elongation, formation of small leaves with a thin leaf blade, overall low productivity and low adaptation potential of G. lutea plants to ex vitro and in situ conditions. Increasing the light flux intensity to 44 W/m2 and increasing the red wave proportion up to 20.3% allows not only to improve the bioproductivity of G. lutea plants which are cultivated in vitro, but also to increase the coefficient of microclonal reproduction without the additional use of exogenous growth regulators.

Study of DNA polymorphism of 7 coenopopulations of Siberian stone pine (Pinus sibirica) growing in theKuznetsk Alatau. Methods. Nuclear microsatellite loci developed for P. sibirica were used as genetic markers. Results. 44 allelic variants were identified from 11 nuclear microsatellite loci, which significantly differ in the composition and frequency of occurrence of the studied P. sibirica coenopopulations. The highest level of allelic diversity is found in loci Ps_80612 and Ps_1502048, where 8 and 7 alleles were identified, respectively. The calculation of the main parameters of genetic diversity showed a relatively low level of polymorphism in the studied samples (NA = 3.078; NE = 1.877; HE = 0.445; HO = 0.401). The assessment of the degree of genetic differences between populations using the Nei genetic distance (DN) showed that, despite the low genetic differentiation (DN varies from 0.019 to 0.061), the differences between them can be traced quite clearly. Conclusions. Differences in the level of genetic polymorphism of P. sibirica is defined by the presence of orographic and phytocoenotic barriers between coenopopulations, as well as a high degree of ecological and anthropogenic extremity of individual growth sites. \u0000Keywords: Pinus sibirica, Kuznetsk Alatau, microsatellites, genetic diversity, heterozygosity.","PeriodicalId":12181,"journal":{"name":"Faktori eksperimental'noi evolucii organizmiv","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78295838","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}

We analyzed the recreational load on 18 park ecosystems within the city of Kyiv.

The created map-scheme according to the integrated indicator of the severity of the impact (W) reflects the ecological situation in the studied Kyiv park ecosystems and indicates their significant transformation in the conditions of the megalopolis. The tendency to decrease the number and intensity of manifestations of recreational exposure with increasing severity of exposure (W) is calculated. According to GIS modeling by W and taking into account the prevailing wind directions in the city of Kyiv, it was found that 50% of the studied parks are in critical danger, 30% – in a threatening condition, only the «Pushcha-Vodytsya» park is in a stable condition.
