This article is devoted to analysis of the modern problems of book publishing in the context of national information space. Development of the Ukrainian state is impossible without development of national book publishing, which is a part of its information space. In Ukraine, as one of the post-Soviet states, the formation of new information and communication system is based on its own information tradition, mentality and features of spiritual culture of the Ukrainians. It plays an important role in shaping culture, spirituality, comprehensive vision and consciousness of the nation. They were and they are a source of knowledge and the most effective way of its transfer. The transience of processes occurring the era of information society, radical socio-economic reforms, sectoral technological revolution requires the continuous scientific researches and analysis, identifying the trends in publishing industry as one of the most important factors in the state’s democratic progress. The author summarizes the development of book publishing of Ukraine and shows its role and place in the modern information society. The study of the modern book publishing is impossible without digression into the past, without finding out the roots of studying of the analysis object. The specific problems of the book industry are identified. It is concluded that in the modern Ukraine the publishing business has intensified, although the positive changes are taking place very slowly: the appropriate economic conditions for development of the publishing industry have not been created, the equipment are outdated; editorial, publishing and printing equipment of domestic manufacture are nonavailable; introduction of advanced technology are low; purchasing ability of the population is low; the sales network of printed products has been destroyed and so on. The businesses are becoming increasingly uneconomical. We propose some measures to improve this situation, strengthening the role of industry in the national information space. The key to improve the situation may be systematic and persistent efforts of the Ukrainian government to support the industry.The reason is that a comprehensive study requires from the performers not only historical knowledge, but also economic, managerial, psychological, political efforts and so on. The most important thing that the society and the state should need is the component of doctrine of information security in the context of the national security

CK2 is a Ser/Thr protein kinase overexpressed in many cancers. It is usually present in cells as a tetrameric enzyme, composed of two catalytic (α or α’) and two regulatory (β) subunits, but it is active also in its monomeric form, and the specific role of the different isoforms is largely unknown. CK2 phosphorylates several substrates related to the uncontrolled proliferation, motility, and survival of cancer cells. As a consequence, tumor cells are addicted to CK2, relying on its activity more than healthy cells for their life, and exploiting it for developing multiple oncological hallmarks. However, little is known about CK2 contribution to the metabolic rewiring of cancer cells. With this study we aimed at shedding some light on it, especially focusing on the CK2 role in the glycolytic onco-phenotype. By analyzing neuroblastoma and osteosarcoma cell lines depleted of either one (α) or the other (α’) CK2 catalytic subunit, we also aimed at disclosing possible pro-tumor functions which are specific of a CK2 isoform. Our results suggest that both CK2 α and α’ contribute to cell proliferation, survival and tumorigenicity. The analyzed metabolic features disclosed a role of CK2 in tumor metabolism, and suggest prominent functions for CK2 α isoform. Results were also confirmed by CK2 pharmacological inhibition. Overall, our study provides new information on the mechanism of cancer cells addiction to CK2 and on its isoform-specific functions, with fundamental implications for improving future therapeutic strategies based on CK2 targeting.

In recent years, research on spermine (Spm) has turned up a lot of new information about this essential polyamine, especially as it is able to counteract damage from abiotic stresses. Spm has been shown to protect plants from a variety of environmental insults, but whether it can prevent the adverse effects of drought has not yet been reported. Drought stress increases endogenous Spm in plants and exogenous application of Spm improves the plants’ ability to tolerate drought stress. Spm’s role in enhancing antioxidant defense mechanisms, glyoxalase systems, methylglyoxal (MG) detoxification, and creating tolerance for drought-induced oxidative stress is well documented in plants. However, the influences of enzyme activity and osmoregulation on Spm biosynthesis and metabolism are variable. Spm interacts with other molecules like nitric oxide (NO) and phytohormones such as abscisic acid, salicylic acid, brassinosteroids, and ethylene, to coordinate the reactions necessary for developing drought tolerance. This review focuses on the role of Spm in plants under severe drought stress. We have proposed models to explain how Spm interacts with existing defense mechanisms in plants to improve drought tolerance.

People believe repeated statements more than new ones—the repetition-induced truth effect. It is prominently explained with processing fluency: The subjective ease of processing repeated versus new information. To date, the role of affective processes for the truth effect is rather unclear. From a theoretical perspective, people should rely more on fluency under positive than under negative affect. Here, we tested whether an affective picture presented before a statement influences the repetition-induced truth effect. Thirty-five participants took part in two sessions that were a week apart. In both sessions, they rated the truth status of statements. In session 2, repeated and new statements were intermixed, and each statement was preceded by a positive, negative, or neutral picture. We expected participants to rely more on fluency as a cue to truth in the positive than in the negative affective condition. However, although we replicated the repetition-induced truth effect, the interaction between affect and repetition was insignificant, but we observed a significant main effect of affect—statements were rated as truer after a positive rather than a negative or neutral picture. Our results suggest two independent mechanisms that enhance the subjective truth of statements: repetition and positive affect.

Systematic monitoring of ecologically significant species – predatory mollusc Rapana venosa Valenciennes, 1846 populations – is an important part of the Black Sea monitoring. The study of the role of R. venosa in contemporary marine ecosystem is of considerable interest. In June-September 2015-2016 the study of consorting relations of rapana was conducted in situ with a parallel sampling by diver. In the course of research new information about the interaction of R. venosa with the fish fauna has been obtained. Of particular importance for fishes is the presence of rapana in the sandy bottom zone, where there are no natural shelters, and food resources are limited. The most important for the fish is the presence on the rapana shells of algal fouling and epiphyton. The shells of invader – R. venosa – and its fouling create additional opportunities for the survival of some fish fauna representatives juveniles of the Black Sea. The data obtained extend the concepts of ecological role of mollusc – invader R. venosa, as well as the ecology and ethology of several fish species.

Chromosome Y Isodicentrics in two Cases with Ambiguous genitalia and Features of Turner SyndromeKaryotype investigations using classical cytogenetics, fluorescencein situhybridization (FISH) and polymerase chain reaction (PCR) techniques were used for the characterization of Y chromosome structural anomalies found in two patients with ambiguous genitalia and features of Turner syndrome. Both exhibited mosaic karyotypes of peripheral blood lymphocytes. The karyotype was 45, X[90]/ 46, X, idic(Y)(p11.3).ish idic(Y) (wcpY+, DXYS130++,SRY++,DYZ3++,DYZ1++, DYS224++)[10] in one case, and the karyotype was 45, X[65]/46, X, idic(Y) (q11).ish idic(Y)(SRY++, RP11-140H23-)[35] in the other case. Derivative Y chromosomes were different in shape and size and positive for the SRY gene, a common underlying element of ambiguous genitalia phenotypes. These results add new information concerning the role of Y chromosome structural abnormalities in sex determination pathway perturbation which are poorly understood, and highlight the importance of the sex chromosomes integrity for a normal sex phenotype development.
