The media space of the educational sphere as a logistic system: features of management and personality formation

Development of digitization (including education) leads to difficulties in management and regulation of important multidimensional dynamic social economical systems, where problems of efficient management occur requiring for interdisciplinary approach and active application of information technologies and computers. It is required to develop new methods of risk management (in the fields of national security, personal security), since information nonmilitary action as the most important hazard of hybrid wars is precepted as motion along the road of progress, democracy, tolerance. The research objective implies search and implementation of optimum management of stepwise digitization of education by means of monitoring and reconfiguration of digital platforms as elements of global logistic system (with consideration for consciental risks). Targets include analysis of features of dynamics and management of digitization of educational platforms in relation with maturity of social institutions, COVID-19, ecology of information space, degree of informatization of society, role and composition of mental structures, etc.; detection of factors influencing dynamics of persons and social institutions involved in education. The interrelation between digitization of education and development of educational platforms has been described. The conclusions have been made about the advantages and disadvantages of management formed by analogy with management of dynamic processes running on classical logistic systems. Recommendations have been given on how to reduce the dependence of a human on behavioral stereotypes imposed by various algorithmic energy information structures. In the frames of community, this would provide productive existence in unique personal space, efficient communication with surrounding people together with preservation of mentality and self-consciousness, cultural and national identity

GADD34 Ablation Exacerbates Retinal Degeneration in P23H RHO Mice

The UPR is sustainably activated in degenerating retinas, leading to translational inhibition via p-eIF2α. Recent findings have demonstrated that ablation of growth arrest and DNA damage-inducible protein 34 (GADD34), a protein phosphatase 1 regulatory subunit permitting translational machinery operation through p-eIF2α elevation, does not impact the rate of translation in fast-degenerating rd16 mice. The current study aimed to validate whether P23H RHO mice degenerating at a slower pace manifest translational attenuation and whether GADD34 ablation impacts the rate of retinal degeneration via further suppression of retinal protein synthesis and apoptotic cell death. For this study, mice were examined with ERG and histological analyses. The molecular assessment was conducted in the naïve and LPS-challenged mice using Western blot and qRT-PCR analyses. Thus, this study demonstrates that the P23H RHO retinas manifest translational attenuation. However, GADD34 ablation resulted in a more prominent p-eIF2a increase without impacting the translation rate. GADD34 deficiency also led to a reduction in scotopic ERG amplitudes and an increased number of TUNEL-positive cells. Molecular analysis revealed that GADD34 deficiency reduces the expression of p-STAT3 and Il-6 while increasing the expression of Tnfa. Overall, the data indicate that GADD34 plays a multifunctional role. Under chronic UPR activation, GADD34 acts as a feedback player, dephosphorylating p-eIF2a, although this role does not seem to be critical. Additionally, GADD34 controls cytokine expression and STAT3 activation. Perhaps these molecular events are particularly important in controlling the pace of retinal degeneration

Opisthorchis felineus infection and cholangiocarcinoma in the Russian Federation: a review of medical statistics

Opisthorchis felineus (O. felineus) occurs in Western Siberia and many other parts of the Russian Federation (RF). The true extent of its distribution is not known. Chronic infection may lead to severe hepatobiliary morbidity. According to surgical and experimental reports, long-term infestation might significantly increase the risk for cholangiocarcinoma (CCA). To date, no association between O. felineus infection and CCA has been demonstrated. The objective of this study was to review existing health data on the incidence of O. felineus infection and on the incidence of CCA in the RF. We reviewed the official medical statistics on reported O. felineus infection and CCA in 83 political/geographical units of the RF, covering the period January 2011-December 2013. Annual incidence data were obtained from Rospotrebnadzor and from official medical statistics. We calculated the average annual incidence of infection and cancer. The average annual incidence of O. felineus was 24.7±9.0 cases per 100,000 population. The highest incidence was observed in Khanty-Mansiysk district (599.7 cases per 100,000 population per year). In 27 geographical units, no O. felineus cases were reported. The incidence of liver and intrahepatic bile duct cancers was 4.8±0.2 cases per 100,000 population; the highest rate was reported in Sakha Republic and Tomsk Oblast (14.5 and 9.3 cases per 100,000 population), and the lowest in Yamalo-Nenets Autonomous Okrug (0.9 cases per 100,000 population). O. felineus incidence was not associated with the mean annual incidence of liver and intrahepatic bile duct cancers (r=0.20, p=0.07). This study documents the importance of opisthorchiasis in certain endemic areas and presents the best available data on associations between O. felineus infection and liver/intrahepatic bile duct cancers in RF. The findings support the need to implement a public health control programme against liver fluke infections and to increase the availability of anthelmintic treatment. Further studies are warranted to assess the contribution of opisthorchiasis to the CCA in RF
