INFLUENCE OF THE CREATIVE ECONOMY ON MODERN MANAGEMENT OF CREATIVE INDUSTRIES

The features of the modern approach to the organization of working process in creative industries, where the key is the concept of “teal organization” distinctive quality characteristics of which are self-government and self-organization, implying independent implementation of the work processes and projects realization by the employees, have been considered. The rules of creating competent communication with the creative class, people who are the driving force of the creative economy, play an essential role in organizing the management of creative industries in modern society. The functioning of “teal organizations” exclusively within the framework of a creative economy, where the greatest value is the realization of the creative potential of the employee, has been examined in the article

Development of selective inhibitors of phosphatidylinositol 3-kinase C2α

Phosphatidylinositol 3-kinase type 2α (PI3KC2α) and related class II PI3K isoforms are of increasing biomedical interest because of their crucial roles in endocytic membrane dynamics, cell division and signaling, angiogenesis, and platelet morphology and function. Herein we report the development and characterization of PhosphatidylInositol Three-kinase Class twO INhibitors (PITCOINs), potent and highly selective small-molecule inhibitors of PI3KC2α catalytic activity. PITCOIN compounds exhibit strong selectivity toward PI3KC2α due to their unique mode of interaction with the ATP-binding site of the enzyme. We demonstrate that acute inhibition of PI3KC2α-mediated synthesis of phosphatidylinositol 3-phosphates by PITCOINs impairs endocytic membrane dynamics and membrane remodeling during platelet-dependent thrombus formation. PITCOINs are potent and selective cell-permeable inhibitors of PI3KC2α function with potential biomedical applications ranging from thrombosis to diabetes and cancer

Clinical features of post-COVID-19 period. Results of the international register “Dynamic analysis of comorbidities in SARS-CoV-2 survivors (AKTIV SARS-CoV-2)”. Data from 6-month follow-up

Aim. To study the clinical course specifics of coronavirus disease 2019 (COVID-19) and comorbid conditions in COVID-19 survivors 3, 6, 12 months after recovery in the Eurasian region according to the AKTIV register. Material and methods.The AKTIV register was created at the initiative of the Eurasian Association of Therapists. The AKTIV register is divided into 2 parts: AKTIV 1 and AKTIV 2. The AKTIV 1 register currently includes 6300 patients, while in AKTIV 2 — 2770. Patients diagnosed with COVID-19 receiving in- and outpatient treatment have been anonymously included on the registry. The following 7 countries participated in the register: Russian Federation, Republic of Armenia, Republic of Belarus, Republic of Kazakhstan, Kyrgyz Republic, Republic of Moldova, Republic of Uzbekistan. This closed multicenter register with two nonoverlapping branches (in- and outpatient branch) provides 6 visits: 3 in-person visits during the acute period and 3 telephone calls after 3, 6, 12 months. Subject recruitment lasted from June 29, 2020 to October 29, 2020. Register will end on October 29, 2022. A total of 9 fragmentary analyzes of the registry data are planned. This fragment of the study presents the results of the post-hospitalization period in COVID-19 survivors after 3 and 6 months. Results. According to the AKTIV register, patients after COVID-19 are characterized by long-term persistent symptoms and frequent seeking for unscheduled medical care, including rehospitalizations. The most common causes of unplanned medical care are uncontrolled hypertension (HTN) and chronic coronary artery disease (CAD) and/or decompensated type 2 diabetes (T2D). During 3- and 6-month follow-up after hospitalization, 5,6% and 6,4% of patients were diagnosed with other diseases, which were more often presented by HTN, T2D, and CAD. The mortality rate of patients in the post-hospitalization period was 1,9% in the first 3 months and 0,2% for 4-6 months. The highest mortality rate was observed in the first 3 months in the group of patients with class II-IV heart failure, as well as in patients with cardiovascular diseases and cancer. In the pattern of death causes in the post-hospitalization period, following cardiovascular causes prevailed (31,8%): acute coronary syndrome, stroke, acute heart failure. Conclusion. According to the AKTIV register, the health status of patients after COVID-19 in a serious challenge for healthcare system, which requires planning adequate health system capacity to provide care to patients with COVID-19 in both acute and post-hospitalization period

Design of 16S rRNA-targeted oligonucleotide probes for detecting cultured and uncultured archaeal lineages in high-temperature environments

In order to facilitate the evaluation of archaeal community diversity and distribution in high-temperature environments, 14 16S rRNA oligonucleotide probes were designed. Adequate hybridization and wash conditions of the probes encompassing most known hyperthermophilic Archaea, members of the orders Thermococcales, Desulfurococcales and Sulfolobales, of the families Methanocaldococcaceae, Pyrodictiaceae and Thermoproteaceae, of the genera Archaeoglobus, Methanopyrus and Ignicoccus, and of the as yet uncultured lineages Korarchaeota, Crenarchaeota marine group I, deep-sea hydrothermal vent euryarchaeotic group 2 (DHVE 2), and deep-sea hydrothermal vent euryarchaeotic group 8 (DHVE 8) were determined by dot-blot hybridization from target and non-target reference organisms and environmental clones. The oligonucleotide probes were also used to evaluate the archaeal community composition in nine deep-sea hydrothermal vent samples. All probes, except those targeting members of Sulfolobales, Thermoproteaceae, Pyrodictiaceae and Korarchaeota, gave positive hybridization signals when hybridized against 16S rDNA amplification products obtained from hydrothermal DNA extracts. The results confirmed the widespread occurrence of Thermococcales, Desulfurococcales, Methanocaldococcaceae and Archaeoglobus in deep-sea hydrothermal vents, and extended the known ecological habitats of uncultured lineages. Despite their wide coverage, the probes were unable to resolve the archaeal communities associated with hydrothermally influenced sediments, suggesting that these samples may contain novel lineages. This suite of oligonucleotide probes may represent an efficient tool for rapid qualitative and quantitative characterization of archaeal communities. Their application would help to provide new insights in the future into the composition, distribution and abundance of Archaea in high-temperature environments

Isolation of a Ubiquitous Obligate Thermoacidophilic Archaeon From Deep-Sea Hydrothermal Vents

Deep-sea hydrothermal vents are important in global biogeochemical cycles, providing biological oases at the sea floor that are supported by the thermal and chemical flux from the Earth\u27s interior. As hot, acidic and reduced hydrothermal fluids mix with cold, alkaline and oxygenated sea water, minerals precipitate to form porous sulphide–sulphate deposits. These structures provide microhabitats for a diversity of prokaryotes that exploit the geochemical and physical gradients in this dynamic ecosystem. It has been proposed that fluid pH in the actively venting sulphide structures is generally low (pH \u3c 4.5), yet no extreme thermoacidophile has been isolated from vent deposits. Culture-independent surveys based on ribosomal RNA genes from deep-sea hydrothermal deposits have identified a widespread euryarchaeotal lineage, DHVE2 (deep-sea hydrothermal vent euryarchaeotic 2) Despite the ubiquity and apparent deep-sea endemism of DHVE2, cultivation of this group has been unsuccessful and thus its metabolism remains a mystery. Here we report the isolation and cultivation of a member of the DHVE2 group, which is an obligate thermoacidophilic sulphur- or iron-reducing heterotroph capable of growing from pH 3.3 to 5.8 and between 55 and 75 °C. In addition, we demonstrate that this isolate constitutes up to 15% of the archaeal population, providing evidence that thermoacidophiles may be key players in the sulphur and iron cycling at deep-sea vents
