Role of membrane lipids in the regulation of erythrocytic oxygen-transport function in cardiovascular diseases

The composition and condition of membrane lipids, the morphology of erythrocytes, and hemoglobin distribution were explored with the help of laser interference microscopy (LIM) and Raman spectroscopy. It is shown that patients with cardiovascular diseases (CVD) have significant changes in the composition of their phospholipids and the fatty acids of membrane lipids. Furthermore, the microviscosity of the membranes and morphology of the erythrocytes are altered causing disordered oxygen transport by hemoglobin. Basic therapy carried out with the use of antiaggregants, statins, antianginals, beta-blockers, and calcium antagonists does not help to recover themorphofunctional properties of erythrocytes. Based on the results the authors assume that, for the relief of the ischemic crisis and further therapeutic treatment, it is necessary to include, in addition to cardiovascular disease medicines, medication that increases the ability of erythrocytes’ hemoglobin to transport oxygen to the tissues. We assume that the use of LIM and Raman spectroscopy is advisable for early diagnosis of changes in the structure and functional state of erythrocytes when cardiovascular diseases develop

Media space of the modern school

What should be the media of a modern education institution? How is the educational organization supposed to be represented in social media? What methods of increasing the level of media literacy of teachers and students should optimally use?As the purpose of this study the authors can see in the development and presentation of an optimal model of media space for modern educational institutions which will take into account not only the changes in the education process, but also the needs of the modern audience – teachers, students, parents, and educational partners. The resources of “Moscow e-school” become part of the educational media sphere of modern educational organizations.Resources and methods: resources of an educational institution, namely, social media, blogs and microblogs, users’ accounts, channels, educational platforms, which present the work of educators. The importance of analyzing media of the modern educational institution is that media-education serves as a pedagogical system, allowing the use of modern techniques and technologies through the development of critical thinking, which occurs under the influence of information flows. In this regard, there is a need for the comprehensive approach to the media organization in the modern school. An integral element of the complex approach is the creation of conditions for the development of media literacy for teachers and learners.The result of this research is the optimal model of media space for the modern school, which includes social networking profiles, microblogging, blogs, users’ accounts, and web resources, each of which has its own purpose and functional features.As a conclusion we can note that one of the core values of the media model is the development of creative and critical thinking, the acquisition of experience and tools of media, independent search, the ability to use information flows for the effective communication, solving educational and cognitive, other personal problems and tasks, i.e. the orientation is not so much on the knowledge as on the acquisition of positive experience of the independent work
