Anomalous Perception: An Umbrella Review of the Meta-Analytic Evidence
Authors: Tressoldi Patrizio , Storm Lance
Published: November 2020

Objective: The aim of this study was to assess the results of all meta-analyses on anomalous cognition conducted between 1989 and 2021 in order to find moderators associated with greater effect sizes. Method: We included all meta-analyses of studies related to anomalous cognition published up to 2021.Results: Our dataset, accumulated over more than 80 years of investigation, refers to 11 meta-analyses related to six different states of consciousness. The evidence clearly shows that anomalous cognition seems possible and its effects can be enhanced by using a combination of some non-ordinary or altered states of consciousness (e.g., dreaming, ganzfeld, etc.), coupled with free-response procedures, or neurophysiological dependent variables. These conditions facilitate an alternative form of cognition seemingly unconstrained by the known biological characteristics of the sense organs and the brain. Conclusion: The accumulated evidence expands our understanding of the mind-brain relation and the nature of the human mind.
A Review of the LGBTQ+ Work-Family Interface: What Do We Know and Where Do We Go from Here?
Authors: Murphy Lauren D , Thomas Candice L , Cobb Haley R. , Hartman Alexius Elise
Published: November 2020

Work-family research has blossomed over the past several decades but mostly remains focused on traditional couples and heteronormative individuals. However, research suggests that LGBTQ+ employees face unique challenges, such as discrimination and stigma, that impact their work-family interface in ways that current work-family research may not be fully capturing. We propose a review and synthesis that summarizes current LGBTQ+ and work-family literature with four primary goals: (1) identify predictors and outcomes of the work-family interface for LGBTQ+ employees, (2) integrate empirical findings and current theory into a recently developed framework to delineate our understanding of LGBTQ+ work-family experiences, (3) provide direction for future research, and (4) provide recommendations on translating the current findings into practice. Our results identify k = 74 studies that cover the work-family interface and LGBTQ+ individuals. This comprehensive and integrated review will help inform researchers on how to best address unique research questions for LGBTQ+ employees and provide employers with empirical evidence as they develop inclusive policies, cultures, and workforces.

Published: November 2020

Abstract:Objectives. Disruptive behaviour disorders (DBDs) are common reason for referral among children/adolescents. The present meta-analysis aims to estimate the efficacy of psychosocial treatments for adolescents with DBDs. Method. PRISMA-compliant systematic review, MEDLINE/PubMED/PsycINFO/Cochrane Central Register of Controlled Trials, last search April 5th, 2020. Eligible were randomized controlled trials (RCTs) administering psychosocial interventions to adolescents with symptoms of/full- blown DBDs. Out of 6,006 initial hits, random-effect meta-analysis (with sensitivity, subgroup and meta-regression analyses) was conducted on 18 cohorts, in 17 RCTs from 16 publications. Primary outcome: externalizing behaviors at RCT endpoint (standardized mean difference [SMD]). Secondary outcome: acceptability (drop-out odds ratio [OR]). Risk of bias was assessed with Risk of Bias Tool 2. Results. Seventeen RCTs, including 1,954 adolescents, were included. Mean age was 14.09 (DS 1.33), 61% were male. Mean duration of RCT was 12 weeks, and of follow-up eight (DS 3.98) months. Some concern on risk of bias emerged in twelve studies, high in six. In main analyses, psychosocial interventions had a large effect size at RCT endpoint (SMD=0.98, 95%CI -0.55 to -1.38, k=18), and were acceptable (drop-out OR=1.29, 95%CI 0.62 to 2.70, k=13). Such beneficial effect did not persist at follow-up (SMD=-0.36, 95%CI 0.06 to -0.78, k=10). Family format was the most effective. No clinically significant moderator was found. Conclusion. In conclusion, psychosocial interventions involving family of adolescents with DBDs symptoms/disorders are effective, and acceptable in the short term, but not effective at follow-up. Future studies should focus on strategies to maintain short-term efficacy of psychosocial interventions in DBDs.
The representational glue for incidental category learning is alignment with task-relevant behavior
Authors: Roark Casey L , Lehet Matthew , Dick Frederic , Holt Lori L.
Published: November 2020

This is a pre-print of the manuscript in press in the Journal of Experimental Psychology: Learning, Memory, and Cognition: Roark, C. L., Lehet, M. I., Dick, F., & Holt, L. L. (in press). Category learning is fundamental to cognition, but little is known about how it proceeds in real-world environments when learners do not have instructions to search for category-relevant information, do not make overt category decisions, and do not experience direct feedback. Prior research demonstrates that listeners can acquire task-irrelevant auditory categories incidentally as they engage in primarily visuomotor tasks. The current study examines the factors that support this incidental category learning. Three experiments systematically manipulated the relationship of four novel auditory categories with a consistent visual feature (color or location) that informed a simple behavioral keypress response regarding the visual feature. In both an in-person experiment and two online replications with extensions, incidental auditory category learning occurred reliably when category exemplars consistently aligned with visuomotor demands of the primary task, but not when they were misaligned. The presence of an additional irrelevant visual feature that was uncorrelated with the primary task demands neither enhanced nor harmed incidental learning. By contrast, incidental learning did not occur when auditory categories were aligned consistently with one visual feature, but the motor response in the primary task was aligned with another, category-unaligned visual feature. Moreover, category learning did not reliably occur across passive observation or when participants made a category-nonspecific, generic motor response. These findings show that incidental learning of categories is strongly mediated by the character of coincident behavior.
The Symbols Role in the Creation of a European Identity
Authors: Prisacariu Ioana-Sabina
Published: November 2020

The present paper focuses on the symbolic aspects of the process of formation, sustainment, and change of identity in the European Union. We first establish the role of the symbolisms and symbols in forming links among European citizens and in shaping a European identity.We present a number of initiatives, which have been taken, aimed at forming a collective identity related to the concerns expressed in the recent years over the democratic deficit of the European Union. We consider Andonnino Reports especially significant in this sense through the recommendation of adopting Community symbols. After presenting other activities organized with this aim, in education, culture, and youth fields, we argue that the symbols established by the Constitutional Treaty are the most readily identifiable symbols of integration process.We consider important to have a theoretical presentation of the social and anthropological functions of the symbols. The role of the national symbols of any state is to provide an identity, having at the same time a unifying and a federating power. We show the political implication of the symbols at the level of European citizens. The citizens can be influenced by means of symbols and their symbolisms, to leave aside their differences and act in the common public good. We can conclude that the first important steps to emerging European Union as a new post-national political system (where the national interest coincides with the European interest) have been made. We emphasize how the European symbols such as the flag, the anthem, the motto, the currency, and the Europe Day help to make the European Union more legitimate in the eyes of its citizens by creating emotive images and rites.At the end of the paper, we describe the 9 May Day as a performance of a ritual festivity. We have in mind especially the capacity of this moment to act as a sequence of events within a fixed space and time and to involve simultaneously all stimuli. Our aim is to show how particular aspects of the process of construction of a European identity work in practice, in relation to the symbolic context of ideologies, images, and worldviews.
Gender, Labor, and Geography: Mapping the Economic Life Cycles of German-born and Irish-born Immigrants in 1880 New York City
Authors: Arsen Celia
Published: November 2020

This thesis examines the relationship between gender-based occupational segregation and gender-based residential patterns in 1880 New York City. Specifically, it finds that that Irish-born immigrants were more likely to be employed in highly gender-segregated occupations than their German-born counterparts. This had a spatial impact on the residential patterns of Irish-born men and women. Because Irish-born immigrants tended to work in highly gender-segregated occupations that were located in different parts of the city, Irish-born men and women disproportionately lived in different areas. The paper discusses some of the historical and contextual factors that explain why Irish-born women were more likely than German-born women to go into highly gender-segregated occupations. Lastly, it shows how this relationship between occupational segregation and geography impacted the economic life cycles of these immigrant women. In particular, it identifies the rate at which women left the workforce after getting married or having children.
Windows of Repression: Using COVID-19 Policies against Political Dissidents?

Published: November 2020

What explains the great variation in the adoption, timing, and duration of government policies made in response to the COVID-19 pandemic? In this paper, we explore whether government incentives to repress domestic dissidents influence their responses to the COVID-19 pandemic. We argue that containment policies are observationally equivalent to those that abusive governments would use to limit domestic dissent --- i.e., policies that restrict citizen's freedom of movement. This creates an opportunity for abusive governments to engage in repressive behavior without countervailing pressure from citizens and the international community. Following this logic, we expect abusive governments to be more likely to adopt restrictive policies, adopt them earlier in the course of the pandemic, and take longer to relax restrictions. Empirically, we find that governments that have recently engaged in state violence against civilians or abused citizens' human rights were about 10 percent more likely to enact lockdown and curfew policies, and these policies were implemented approximately 48 days earlier in the course of the pandemic and kept in place for approximately 23 more days than less repressive countries. Overall, our results advance our understanding of how the repressiveness of state institutions can shape policy responses to a global health crisis.

Analysis of the Effect of Trade Balance on Manufacturing: Evidence from the United States
Authors:   Department of Economics, Eastern Illinois University, Adom Assandé D.
Published: November 2020

The relationship between a country’s manufacturing industry and net trade carries a great deal of complexity and proves critical as the economy matures. Moreover, debates in public arenas are oftentimes not helpful in alleviating confusions. This study attempts to empirically explore the nature of this relationship for the United States in particular. Using a set of structural vector auto-regressions, it reveals that the development of the manufacturing sector is inhibited in the long-run by worsening trade balances. However, this relationship does not appear significant. The implication of this finding weakens arguments singling out negative trade balances as driving forces behind the perceived woes of US manufacturing. Keywords: Manufacturing, Trade balance, United States, Cointegration, Vector auto-regression. JEL Classification: F14, F60, C51.

A Concept for Rapid Prediction of Microbiological Reduction in Automatic Dish Cleaning Processes: The Microbiological Inactivation Equivalent (MIE) Unit
Authors: Schulze Struchtrup Sarah , Stamminger Rainer , Amberg Caroline , Bockmühl Dirk , Brands Britta
Published: November 2020

The aim of this study was to establish a simple model describing the microbial reduction of a cleaning process by only using physical parameters of a given cleaning process (time and temperature) together with microorganism-specific inactivation parameters. The \Microbiological Inactivation Equivalent (MIE) unit" representing the time-temperature integral of a dish treatment process for a specific microorganism was developed. Microbiological reduction in suspension and dishwasher tests was tested in parallel. The microorganism-specific inactivation parameters were adjusted by fitting the MIE units to the experimental reduction factors gained. The mean square deviation between reduction factors and MIE units calculated was on average < 1 (Enterococcus faecium: 0.87, Micrococcus luteus: 0.79) in suspension tests and 1.09 (Enterococcus faecium) and 1.03 (Micrococcus luteus) in dishwasher tests. The MIE model can be used as a simplified method to predict the hygienic performance of a specific cleaning process under well-defined conditions.

Published: November 2020

Hemp seed oil has good sun protection, repair, anti-allergy and anti-aging effects, and is a high quality raw material for the production of skincare products. However, the influence of surfactants and co-surfactants on the emulsification of hemp seed oil in aqueous solution has been rarely investigated. In this investigation, the surfactants and co-surfactants which were suitable for hemp seed oil emulsion were optimized, and the factors which influence the particle size and the stability of the emulsion were studied. Moreover, the application of hemp seed emulsion in different cosmetics was also further investigated. It was found that sorbitan monooleate/polysorbate-80 and glyceryl stearate were the most effective surfactant and co-surfactant in the emulsification of hemp seed oil. After three months the hemp seed oil emulsion had no layered separation and remained homogeneous at -48C, 258C and 408C. The water-resistant sunscreens and the hemp seed oil sunscreens were homogeneous pastes, had a soft texture and were stable at higher temperatures. No microorganisms were detected in these cosmetic creams. Therefore, hemp seed oil is suitable for sunscreen cosmetic materials.

Study Objective: to determine blood lipids and incidence of dyslipidemia in patients with acute pancreatitis (AP), chronic pancreatitis (CP) and pancreas cancer (PC), and to compare them. Study Design: observational multicentral single-arm cross section clinical case series. Materials and Methods. The study enrolled 44 patients with AP, 97 patients with CP, 45 with PC; age and sex composition of groups was comparable. Blood lipids were measured using standard methods. Study Results. Hypercholesterolemia was more common in CP (58.8%), whereas in AP it was (40.9%, p = 0.049) or PC (15.6%, p = 0.000). The rate of hypertriglyceridemia was comparable. Hypoalphacholesterolemia was more common in PC (80.0%), whereas in AP it was (45.5%, p = 0.001) or CP (27.8%, p = 0.000). There is direct association between increased high density lipoprotein cholesterol (HDLP-C) per 1 mmol/L with CP risk (Exp (B) = 21.618; 95% CI: 4.741–98.582, p = 0.000) and invert association with PC risk (Exp (B) = 0.015; 95% CI: 0.002–0.092, p = 0.000). There is also a correlation between total cholesterol and pancreonecrosis and “specific” CP: increase of 1 mmol/L in total cholesterol results in pancreonecrosis risk reduction of 37.7% (Exp (B) = 0.623; 95% CI: 0.389–0.996, p = 0.048), “specific” CP — of 47.4% (Exp (B) = 0.526; 95% CI: 0.305–0.908, p = 0.021). Conclusion. Hypercholesterolemia was more often diagnosed in CP, hypoalphacholesterolemia — in PC; hypertriglyceridemia was comparable. There is a direct correlation between HDLP-C and PC and inverse correlation — with risk of pancreac cancer. Total cholesterol was reversely associated with the risk of pancreonecrosis and specific CP. The evidence determines the need in additional study of association between pancreatic diseases and blood lipids. Keywords: acute pancreatitis, chronic pancreatitis, pancreatic cancer, dyslipidemia, blood lipids.

Objective of the Review: to analyse available data on stomach cancer prevention. Key Points. Key risk factors for stomach cancer are male gender, age of >50 years old, Helicobacter pylori and smoking. A number of international consensus opinions regulate screening, diagnostics and treatment of precancer changes in stomach; it is assumed to reduce the incidence of this disease. H. pylori eradication is the key method of primary stomach cancer prevention. Modern studies demonstrate that the optimal method of H. pylori eradication is the therapy with bismuth medication, proton pump inhibitor, amoxycillin and clarithromycin for 10–14 days. Conclusion. The most efficient method of stomach cancer prevention is H. pylori eradication, smoking cessation, diet with plenty of vegetables and fruit. Secondary prevention is optimisation of diagnostics, follow-up and treatment of precancer stomach conditions. Keywords: stomach cancer, gastratrophia, Helicobacter pylori, prevention.

The use of the method of seismic data acoustic inversion, in the presence of thick gas cap, can lead to difficulties when building background models of elastic parameters. In this regard, in the conditions of acoustically contrast thin environments within the perimeter of the Russkoye oil and gas condensate field, in addition to the standard version based on the well data, the authors considered a number of modified techniques ("block", "flat", and background models). The use of these background models provided the best results and made it possible to significantly improve the quality of predicting rock properties; based on the drilling results, effective penetration was ensured at 66 %, which was 102 % of the plan. Also, based on the inversion results, it became possible to predict reservoir properties using the Bayesian lithotype classification method.
On Money and Quarantine
Authors: Messineo Francesca
Published: November 2020

During the lockdown, I started perceiving cash as a potentially infected entity, carrying the virus on its surface. This article explores the trajectories and implications of this modified perspective on money by merging different levels of analysis. The attempt to grasp both the social and material significance of this ‘object’ will resound in personal anecdotes from my house. The self-ethnographic approach accounts also for the intimate feelings and the new gaze on money produced within me; the enthusiasm for imagining an economy driven by different rules; nostalgia for the activities I used to pay for; anxieties caused by this unprecedented health crisis; and my curiosity to observe how relationships with people and things have changed. The need to share experiences as a political statement and the desire to put fears and hopes into words guide my work.
Covidiots and the Clamour of the Virus-as-Question
Authors: Lim Bryan
Published: November 2020

Drawing on my experience with gay men in London who, despite COVID-19-related public health guidelines, continue to meet up and congregate so as to engage in a myriad of sexual (and non-sexual) practices, this article grapples with how an insistence on prepandemic intimacies of bodily interactions during a pandemic might prompt us to reconsider our relationship with biomedicine. While these covidiots’ experiments with mortality in the form of dance parties, orgies and casual hook-ups may not be ethically exemplary, this article argues that they are at the very least ethically interesting because they serve as lures through which our other intimacies with temporality, futurity and finitude may be reconsidered.

An analytical review of the evolution of attempts to create, schematic and constructive solutions for energycooled nuclear reactors with nuclear steam overheating and supercritical parameters of the working fluid in the conditions of the former USSR and the Russian Federation was made. A comparison of a number of major technical and economic characteristics of main developments of tube and tank reactors is made, the available information on the results of experimental and industrial operation of AMB reactors structures is considered, their advantages and disadvantages are evaluated in terms of technical perfection, reliability, technical and economic performance as well as environmental safety. The expected reduction in capital costs of 40% during the transition of nuclear power units with a capacity of 1,000 MW to single-circuit promising SCWR reactors is achievable only if the steam temperature rises to 625 °C, which has not yet been mastered even in traditional power engineering. The specific energy intensity of reactor’s active zones promising Russian developments under the SCWR program is in most cases extremely high, which will have a negative impact on the characteristics of nuclear safety. The conclusion is made concerning the high probability of a significant increase in the accident rate of the SCWR reactor cores, due to the insufficient study of the heat transfer process characteristics on the heat transfer surface of the TVEL under the conditions of supercritical parameters of the coolant, in particular, such phenomena as pseudo film boiling and thermoacoustic vibrations. In general, insufficient level of completeness of the latest Russian developments and lack of final conceptual projects were noted, which does not provide sufficient grounds for choosing promising schematic and constructive decisions necessary for making reasonable forecasts about the possibility of using supercritical parameters of the coolant in the modern nuclear power industry in the near future.

Published: November 2020

The existing world experience of practical use of sorption technology and technology of cementing liquid borne radioactive waste of nuclear power plants (NPP) with water-water energetic reactors (WWER) to obtain a product 1suitable for transfer to disposal facilities is considered. It has been concluded that salt cake accumulated in NPP storage facilities is a major problem that determines the further choice of the development and implementation of conditioning technologies. Currently, 18,000 salt cake containers stored at the Zaporizhzhia NPP and Khmelnitskiy NPP storage facilities have exceeded their design life. A possible solution is to change the classification of the salt cake and to classify it as solid radioactive waste. It is noted that the existing tax system for the generation of radioactive waste in Ukraine does not contribute to the choice of conditioning technologies aimed at minimizing the volume of the final product. The prospect of application of the technology of melting in the “cold crucible” for one-stage formation from a evaporator bottoms and salt cake borosilicate glass, guaranteed capable in the conditions of surface disposal to ensure the isolation of radionuclides during the time required for decay to a safe level of radioactivity. It is proposed to create a melting unit according to the modular scheme, when several parallel crucibles with capacity up to 20 kg/h with cheaper highfrequency generators with a capacity of 160 kW are connected to common ventilation system. The urgency of carrying out technical and economic analysis to determine the optimal 56 ISSN 2311-8253 Nuclear Power and the Environment № 3 (18) 2020 solutions for the introduction of effective and economically sound technologies for the processing of evaporator bottoms and salt cake at Ukrainian NPPs is emphasized.

Published: November 2020

Processing of liquid radioactive waste (LRW) includes evaporation followed by vitrification. Reducing the energy consumption of evaporation of LRW is an urgent task. In the article, an attention is paid to the fact that similar technical and economic problems are solved with the desalination of seawater. It is proposed to use well-developed seawater desalination technologies for preliminary evaporation of LRW. For a detailed analysis, desalination technology with mechanical vapor compression (MVC) was selected. This technology is energy-saving because it implements the heat pump principle. MVC technology is highly efficient, simple, and does not lead to the generation of secondary radioactive waste. A mathematical model of a single-stage desalination plant with MVC has been developed, taking into account that the thermodynamic cycle of this process is open. Since there are no data on the physical properties of LRW in the literature, the properties of sea water were used. The design and operational parameters were optimized in order to reduce the cost of 1 m3 of evaporated water. It has been established that the main design parameters affecting the cost of evaporated water are the degree of vapor compression in the compressor and the heat exchange surface area of the evaporatorcondenser. The influence of these parameters on capital and operating costs is shown. The optimal combinations of these parameters are determined. To ensure the optimal operating mode of the installation, it is necessary to maintain the optimum salt content of boiling brine, which is determined by the rate of consumption of the source water. The optimal values of these parameters are calculated in a wide range of salt content of the source water. It is shown that, at low salinity of the initial LRW, evaporation is advisable to be carried out in a multi-stage installation. As a result of the calculations, it was found that the specific cost of evaporation of liquid radioactive waste with an initial salt concentration of 10% to a salt content of 20% using the desalination technology with mechanical vapor compression is 0.843 USD/m3.

The aim of this study is to improve the diagnostic approaches in acute period of spontaneous supratentorial intracerebral hemorrhage by detecting the most informative parameters of spectral analysis of the electroencephalographic pattern in the evaluation of cerebral bioelectrical activity changes caused by the lateral shifts of brain midline structures. Materials and methods. We carried out clinical and paraclinical examination of 156 patients (90 men and 66 women, mean age 66,7±0,8 years) with firstly appeared hypertensive spontaneous supratentorial intracerebral hemorrhage. The diagnosis was based on the findings of computed tomography. Lateral shift was evaluated as an average from septum pellucidum and pineal gland displacements. Clinical neurological investigation included the evaluation according to the National Institute of Health Stroke Scale. Computed electroencephalography was carried out within the first 48 hours from the disease onset. Spectral rhythm power, fronto-occipital gradients, interhemispheric rhythm asymmetry parameters were analyzed. Statistical processing included evaluating differences between the groups studied, logistic regression analysis, ROC-analysis. Results. No lateral shift of brain midline structure was found in 57 (36.5%) patients; lateral shift ranged from 1-5mm was diagnosed in 72 (46.2%) patients; the lateral shift over 5 mm was found in 27 (17.3%) patients. We have found out the following values can be used as electroencephalographic criteria of lateral shift of brain midline structures: values of relative spectral power rhythm of alpha band ≤20,5% in affected hemisphere (Se=79,8%, Sp=77,2%) and ≤17,7% in intact hemisphere (Se=71,7%, 75,4%), fronto-occipital rhythm gradients of alpha2 band >–0,085 in affected hemisphere (Se=71,7%, Sp=63,2%) and >–0,266 in intact hemisphere (Se=80,8%, Sp=54,4%), while relative spectral rhythm power of delta band >48,4% in affected hemisphere (Se=88,9%, Sp=74,2%) and >46,8% in intact hemisphere (Se=92,6%, Sp=72,4%), fronto-occipital rhythm gradients of alpha band >–0,001 in affected hemisphere (Se=81,5%, Sp=65,1%). These values demonstrate disturbances in cerebral bioelectrical activity caused by lateral shift over 5 mm. Conclusions. The values of relative spectral rhythm power and fronto-occipital rhythm gradients of alpha band in affected and intact hemispheres are the most informative parameters of spectral electroencephalographic pattern analysis for detection of bioelectrical brain activity deteriorations caused by the lateral shift of brain midline structure due to acute spontaneous supratentorial intracerebral haemorrhage.

Introduction. CD44 is one of the most used markers of cancer stem cells in colorectal cancer. Even though, the questions of its diagnostic and prognostic value remain open. The aim of the study was to compare CD44 immunohistochemical expression levels in polyps and adenocarcinoma of the distal colon. Materials and methods. Histopathological and immunohistochemical studies of biopsies from 40 patients and surgical material of colorectal adenocarcinoma from 30 patients were carried out. Results. It was figured out that distal colonic polyps are characterized by membranous CD44 expression with the medians of relative areas of CD44+ cells equal to 60,24 (50,22; 70,22) % stromal cells and 15,67 (12,47; 19,47) % epitheliocytes. Colorectal adenocarcinoma is characterized by membranous-cytoplasmic CD44 expression with the medians of relative areas of CD44+ cells equal to 61,26 (42,58 ; 79,15) % stromal cells and 30,60 (24,56 ; 36,45 ) % cancer cells. Comparative analysis of the data obtained for the pTNM stages of colorectal adenocarcinoma revealed some significant differences. The median of CD44+ stromal cells area on the I stage equals to 31,41 (19,87 ; 42,15) % vs. the median of CD44+ stromal cells area on the II stage equals to 48,26 (35,44 ; 61,45) % , р ˂ 0,05; the median of CD44+ stromal cells area on the II stage vs. the median of CD44+ stromal cells area on the III stage equals to 78,36 (61,13 ; 80,06) % , р ˂ 0,05. The median of CD44+ cancer cells area on the III stage equals to 30,35 (21,19 ; 35,47) % vs. the median of CD44+ cancer cells area on the IV stage equals to 31,25 (30,22 ; 41,19) % , р ˂ 0,05. Moreover, it was revealed that the median of CD44+ epitheliocytes area in polyps two-fold smaller than the median of CD44+ cancer cells area in colorectal adenocarcinoma: 15,67 (12,47 ; 19,47) % vs. 30,60 (24,56 ; 36,45 ) % , р ˂ 0,05. Conclusions. Distal colonic polyps are characterized by membranous CD44 expression with the median of CD44+ epitheliocytes area that is two-fold smaller than the median of CD44+ cancer cells area. Colorectal adenocarcinoma is characterized by membranous-cytoplasmic CD44 expression with the median of CD44+ stromal cells area that significantly increases during the tumor progression from I to III stages and with the median of CD44+ cancer cells area that significantly go up during the tumor progression from III to IV stages.

The article provides the data on the morphofunctional state of hepatocytes in the liver of white rats under the subtoxic action of sodium fluoride. Mature rats of the Wistar population (N = 17), weighing 180-210 g, were intragastrically injected with aqueous solutions of sodium fluoride in a dose of 1/10 LD50 at the ratio of 20 mg / kg of animal body weight daily. The subacute experiment lasted 60 days. Studying hepatocytes in the rat liver and assessing their morphological rearrangement at the subcellular level of organization was carried out by electron microscopy. The study of ultrastructural organization of the liver under the influence of sodium fluoride revealed changes in the submicroscopic architecture characteristic of the development of dystrophic processes. Prolonged intoxication with sodium fluoride caused a number of changes in the liver ultrastructurer, manifested by the development of intracellular edema in hepatocytes, swelling of mitochondria, changes in the density of their matrix, partial reduction and loss of cristae, vacuolization and expansion of the cisterns of the granular endoplasmic reticulum, an increase in the number of primary lysosomes, redistribution chromatin of the nucleus and a decrease in the number of ribosomes and glycogen granules. These changes indicate a disruption of bioenergetics of hepatocytes associated with the mitochondrial apparatus and the development of hypoxic processes, which lead to a decrease in the activity of redox reactions occurring at the level of intracellular membranes and organelles.

Male sex hormones in general, and testosterone in particular, play an important role not only during puberty in young men; they are also needed to maintain intercellular interaction in the testes. The question regarding the influence of the central regulation of testosterone synthesis on changes in the testes during prolonged deprivation of the stimulus to testosterone production is still open. The aim of this research was to study changes in the production of nitric oxide and superoxide anion radical, morphological changes in the testes of rats under conditions of prolonged (270 and 365 days) central deprivation of testosterone synthesis. The experiments were carried out on 15 sexually mature white male rats of the Wistar line. The animals were divided into 3 groups of 5 animals in each. The first group (control) received subcutaneous injection of sodium chloride 0.9% for 365 days. In the second and third groups, central deprivation of testosterone synthesis was performed for 270 and 365 days, respectively. Central deprivation of testosterone synthesis was modelled by the administration of dipherelin (triptorelin) in a dose of 0.3 mg / kg subcutaneously. On the 270th day of the experiment, changes were noted in the interstitial tissue, with manifestations of fibrosis. Disturbances in the microvascular bed were manifested by endothelial dysfunction and an increase in the density of the vascular wall, associated with both the qualitative and quantitative composition of altered interstitial cells and microvessels. The 365th day of the experiment, like the previous period of the experiment, was characterized by changes in both parenchymal and interstitial components of the testes. In the interstitial tissue, fibrosis can be noted with a decrease in the quantitative composition of interstitial endocrinocytes. The interstitial spaces between the convoluted tubules are enlarged in comparison with the previous period of the experiment. The production of nitric oxide reduced on 270th and 365th days of the experiment by 68.5% and 42.6%, respectively, and the production of superoxide radical anion was increased in 5 and 5.5 times, respectively. Central deprivation of testosterone synthesis on 270th and 365th days leads to fibrosis and systemic stasis of the interstitial tissue with subsequent disruption of the structural organization of the convoluted seminiferous tubules, violation of hemodynamics, endothelial dysfunction, and an increase in the density of the vascular wall of blood vessels. A decrease in the production of nitric oxide by constitutive isoforms of NO-synthase with central deprivation of testosterone synthesis by 270 and 365 days results in an increase in the production of reactive oxygen species in the testes of rats.
GENERAL FEATURES OF CARIES PATHOGENESIS IN THIRD MOLARS AND AUTOIMMUNE DISEASES
Authors: Talash R. V.
Published: November 2020

This article presents a literature review, the results of the analysis of random samples of third molars removed for various clinical indications (11 samples). The teeth samples were analyzed visually, then their coronal parts were treated with epoxy plastination technique and prepared polished sections were studied microscopically. The analyzed data demonstrate the pathogenesis of fissure caries in our samples studied can be explained in terms of the direct virulent effect of pathogenic bacteria on the organic matter in the superficial dentin and basal enamel with the formation of auto antigens, which, as a result of sensitization of the local immune system, become the initial source of the carious process spreading to other teeth. This gives grounds to identify it with the pathogenesis of autoimmune pathology. It has been established that carious damage to hard tissues on the smooth surfaces of the dental crown begins with the pulp, when it is vital, and stops as a result of its tissue degeneration. It has been shown that a single latent damage to the hard dental tissues is the initial manifestation of the latent stage of the carious process, while multiple defects indicate its further progression. As for the generally accepted classification of caries, according to which superficial, medium and deep caries are distinguished, then, in our opinion, they should be considered as stages of the further process of carious destruction of hard dental tissues. We can suggest the study of the pathogenesis of carious lesions of third molars is necessary in order to prevent the occurrence of autoimmune diseases and increase the effectiveness of their treatment.

DISTANCE EDUCATION IN FURTHER PROFESSIONAL TRAINING IN ENTERPRISES DURING PANDEMIC PERIOD
Authors: Matulčíková Marta , Breveníková Daniela
Published: November 2020

Constraints on our personal and professional life imposed by the COVID 19 pandemic have radically influenced our approach to forms of education, including those used in further professional training of employees. This shift means the focus on distance education as a managed educational form, which is suitable for further professional training. The aim of the paper is to present the implementation of distance education in further professional training in enterprises and based on the empirical research propose ways of improving options of education. Distance education is characterised in terms of its principles and developmental stages. Its first generation was correspondence education. The Learning Management System (LMS) and Learning Content Management System (LCMS) are described as the systems applied in further professional training. The research was conducted by means of the questionnaire method, combined with the pre-research survey. Results of empirical research are presented in tables. Separate parts of the paper deal with ICT application in corporate education (correspondence education, Computer-based training (CBT), Web-based training (WBT), Technology Based Training (TBT) and with the utilisation of Learning Management Systems (LMS). Analysis of respondent opinions shows that respondents tend to prefer the face-to-face form of corporate education. The length of the pandemic is going to affect the spread of e-learning in corporate education and its role in education. The learners’ interest may be expected to be shifted to LCM and LCMS utilisation. The paper is a partial result of the research scheme VEGA No. 1/0309/18 “Social networks in human resource management” supported by the Ministry of Education, Science and Research and Sports, Slovakia
