Ecological and biological features of Triglochin maritima L. in the biotopes of the littoral zone with different degree of flooding on the coast of the White Sea

The study of Triglochin maritima L. was carried out on the Pomor (western) coast of the White Sea, in the Republic of Karelia (64°22'81"N, 35°93'14"E). Morphological analysis of aboveground and underground parts of the clones was performed on virginal plants. Anatomical analysis of leaf sheaths of the current year shoots, rhizomes and adventitious roots was carried out. The viability of pollen was assessed by determining the relative share of normally developed and malformed pollen grains. The content of heavy metals was determined in the soil, sea water and plant samples. The study was carried out on a model transect in the littoral zone on three test plots representing the lower littoral; the middle and the upper littoral zones. Adaptation to wave and storm impact was manifested in a well-developed system of underground organs. In the lower littoral, underground part surpasses the aboveground vegetative organs in terms of the mass and the formation of mechanical tissues. This allows the plants to anchor stronger in the substrate. Pollen analysis confirmed the adaptability of T. maritima plants to the conditions of the lower littoral by a high percentage of normal and, consequently, fertile pollen, which ensures sexual reproduction of the species. T. maritima can be considered as a Fe hyperaccumulator as the plant accumulates very high levels of Fe (22–34 g kg-1), especially in the lower and middle littoral zones, both in underground and aboveground organs. The ability of T. maritima plants to actively deposit metals was revealed on the basis of the coefficient of biological absorption of metals and makes it possible to suggest potential possibility of using the species in phytoremediation technologies on coastal territories

Production of hemo- and immunoregulatory cytokines by erythroblast antigen(+ )and glycophorin A(+ )cells from human bone marrow

BACKGROUND: Erythroid nuclear cells (ENC) of the bone marrow (BM) have not previously been considered as important producers of wide spectrum of haemo- and immunoregulatory cytokines. The aim of the current work was to confirm the production of the main hemo- and immunoregulatory cytokines in human ENC from BM. RESULTS: We used native human BM ENC in our experiments. We for the first time have shown, that the unstimulated erythroblasts (Gl A(+ )or AG-EB(+)) produced a wide spectrum of immunoregulatory cytokines. Human BM ENC produce cytokines such as interleukn (IL)-1β, IL-2, IL-4, IL-6, interferon (IFN)-γ, transforming growth factor (TGF)-β1, tumor necrosis factor (TNF)-α and IL-10. They can be sub-divided into glycophorin A positive (Gl A(+)) and erythroblast antigen positive (AG-EB(+)) cells. To study potential differences in cytokine expression between these subsets, ENC were isolated and purified using specific antibodies to Gl A and AG-EB and the separated cells were cultivated for 24 hours. The cytokine contents of the supernatant were measured by electrochemiluminescence immunoassay. Quantitative differences in TGF-β1 and TNF-α production were found between Gl A(+ )and AG-EB(+ )BM ENC. Furthermore, in vitro addition of erythropoietin (EPO) reduced IFN-γ and IL-2 production specifically by the AG-EB(+ )ENC. Thus, Gl A(+ )and AG-EB(+ )ENC produce IL-1β, IL-2, IL-4, IL-6, IFN-γ, TGF-β1 and TNF-α. Gl A(+ )ENC also produce IL-10. CONCLUSION: Cytokine production by erythroid nuclear cells suggests that these cells might be involved in regulating the proliferation and differentiation of hematopoietic and immunocompetent cells in human BM

Inclusive organizational culture as a culture of diversity acceptance and mutual understanding

The relevance of the study is the need to reform the educational environment based on the values of inclusion to ensure the accessibility of quality education for all people. The purpose of the study is to justify the need an inclusive culture formation as a culture of acceptance of diversity and mutual understanding. The research problem is the lack of development of an inclusive organizational culture is a barrier to ensuring the availability of quality education in a variety of health limitations and the educational needs of students. The study based on the analysis of regulatory documents, comparison and generalization of the available approaches in international and Russian theory and practice on the inclusion values issue in the strategy of educational organizations and the formation of an inclusive organizational culture. Results: it was established that the inclusive agenda in education aggravates the problem of the formation of an inclusive organizational culture as a culture of accepting diversity as a value, advantage, significant educational, upbringing, developing resource; staged, the need for a proactive strategy of the formation of intercultural competencies are justified. © 2019 LLC Ecological Help.

О качестве контента блогов в контексте формирования правовой культуры

Introduction. The relevance of the study is caused by the development of digital technologies, their increasingly active influence on all aspects of society and human life and, consequently, the need of forming the individual's legal culture using the media sphere's resources. The purpose of the study is to analyze the main characteristics and quality of legal Instagram blog content as one of the dynamically developing applications with a multi-million audience of users. Materials and research methods. The research methodology consists of an integrative approach. Information and target analysis of texts and discourse analysis were used to interpret blog content in the context of specific cultural and historical factors. The results of the study and the discussion. The Top Instagram bloggers was compiled using the hashtag #lawyer, blog content studied. Based on the development of quality content criteria - relevance, social significance, completeness, accessibility, practice orientation, personalization, infoesthetics, multi-factor, literacy, and subscriber response-were developed, according to which the analysis of legal content was carried out. The study identified the content of bloggers who position themselves on Instagram as legal experts, analyzed the content of bloggers with more than ten thousand subscribers based on the developed quality criteria. It is identified that high-quality content causes an adequate reaction of users, contains a knowledge component endowed with legal content and aimed at improving the legal culture of the individual Conclusions. Despite the fact that Instagram, like other apps, has more entertainment content, however, users feel the need for knowledges that will let them to constructively solve situation in the legal sphere. It was revealed that high-quality content as socially significant knowledge has an adequate response of Instagram users. This contributes to the development of the individual's legal culture in the context of socio-cultural transformations, when a modern person increasingly has to solve non-standard objectives in a dynamically developing environment, including changes in the legal framework in various fields of activity. © 2020 LLC Ecological Help.

Assessment of bone quality by the technique of multispiral computer tomography in patients with chronic osteomyelitis

Purpose - to study the roentgenomorphological features of the lower limb long bones in patients with chronic osteomyelitis using the technique of multi-spiral computer tomography (MSCT), and to propose the complex of parameters to assess bone quality. Material and methods. Roentgenography and computer tomography of the hips were performed in 49 patients with chronic osteomyelitis of long bones of lower extremities. The studies made using computer tomographs GE Light Speed VCT, Toshiba Aquilion-64, Somatom Smile. Results. The changes in bone structure of proximal femur were characterized by extremely marked polymorphism, and they almost didn’t repeat in the anatomical component. The cortical plate had heterogenous structure with resorption zones in the area of its transfer to the shaft. The character of roentgenomorphological changes in the shaft was individual in all the patients, but there were common manifestations as well which consisted in thickening of the cortical plate, different intensity of periosteal and endosteal layers. The cortical plate was significantly different in density, which exceeded 1700 HU in some places. When osteomyelitic process localized in the knee marked changes affected its all components, they manifested themselves in extended osteoporosis and local osteosclerosis. When osteomyelitic process localized in proximal tibia extensive resorption zones observed, the cortical plate thinned in proximal parts, its density was not more than 350 HU. Conclusion. The data demonstrated that bone quality in patients with chronic osteomyelitis had significant deviations from normal values in terms of changing both its density and architectonics. The deviations consisted in bone density decrease in the meta-epiphyseal part regardless of the process localization, in highly variable density values of the cortical plate as a result of its thickening or thinning, presence of resorption or sclerosis areas

Charge carrier concentration and structural transition temperatures in Heusler alloys Ni50Mn36Sb14-xZx (Z = Al, Ge; X = 0; 1; 2; 3; 4)

The temperature dependences of magnetization and electrical resistance of the Ni50Mn36Sb14-xZx (Z = Al, Ge; x = 0; 1; 2; 3; 4) alloys have been used to determine the structural transition temperatures (STT) such as: Ms, Mf, As and Af (temperatures of the start and finish of martensitic and austenitic transformations, respectively). Effect of various parameters (e/a, Vcell, n) on the STT was studied. Using Hall Effect the concentration of charge carriers n∗ was obtained and it was found that n∗ is not strongly correlated with a behaviour of STT, there is only a general trend with exceptions. © Published under licence by IOP Publishing Ltd.Russian Foundation for Basic Research, RFBR: 18-02-00739The results of this work were obtained within the state assignment of Minobrnauki of Russia (theme “Spin” No. АААА-А18-118020290104-2) and “New functional materials for promising technologies: synthesis, properties, spectroscopy and computer simulation” (No. AAAA-A19-119031890025-9), supported in part by RFBR grant (project No. 18-02-00739)
