Authors: Melnichenko Olga O. , Denisova Elena V. , Zhukova Olga V. , Potekaev Nikolay N.
Published: January 2022

Background. Psoriasis is a chronic inflammatory autoimmune disease characterized by an excessively aberrant hyperproliferation of keratinocytes. The pathogenesis of psoriasis is complex, and the exact mechanism, despite numerous studies, is still unclear. Complex genetic relationships play an important role in the pathogenesis of this skin disease. A large number of genes that are also associated with other diseases are involved in the development of psoriasis. The variety of comorbidities in patients with psoriasis often present challenges to the treatment for dermatosis. Understanding the role of certain genes in the pathogenesis of psoriasis will contribute the development of more effective targeted therapy aimed at blocking the corresponding inflammatory signaling pathways and molecules.
Aim. To analyze and systematize the basic genetic and biological markers of psoriasis.
Materials and methods. The study included research articles on the genetic analysis of psoriasis. The ResNet, PubMed and eLibrary databases were used.
Results and discussion. Basic genetic and biological markers were identified by analysis of literature sources devoted to psoriasis. Attention is paid to the role and effects of single nucleotide polymorphisms, which make it possible to establish a clear association of a number of genes involved in the development of psoriasis. Genes with altered expression in the psoriatic process were considered separately.
Conclusion. The identified biomarkers can be used in targeted biological therapy of psoriasis using biological modulators that block signaling.

Published: January 2022

Some native plants expand their populations rapidly in their home ranges, altering their structure and composition. Bambusa bambos, a native bamboo species, shows a rapid population expansion in tropical moist evergreen forests in the intermediate climatic zone, Sri Lanka. The present study was conducted to evaluate its impacts on the regeneration potential of other native forest species. The seedling emergence, survival and mortality were observed for a period of one year using quadrats laid along 18 transects marked from the forest edge towards the forest interior in forest patches with and without bamboo (+Bb and –Bb, respectively). The results revealed a higher abundance, richness and diversity of seedlings in +Bb than in -Bb, with lianas and herbs contributing more to these differences. However, tree seedlings showed higher turnover rates (recruitment and mortality) in -Bb, indicating their preference for undisturbed habitats. Tree and shrub seedlings survived better in -Bb forests while liana and herbaceous seedlings displaying the opposite. The results indicate that B. bambos spread showed an ability to alter the regeneration potential of native forests probably resulting bamboo-driven changes to micro-environmental conditions in the forest floor.

Authors: Oh JJ , Ra JB , Kim GH
Published: January 2022

This research was performed to investigate the feasibility of using copper-based wood preservative treatment for producing green colour on the bamboo surface and enhancing the fungal decay resistance of treated bamboo. Preliminary outdoor weathering tests were carried out to evaluate the green colour fastness of treated bamboo culms. In addition, fixation and leaching tests were also conducted to evaluate the safety of preservative-treated bamboo. A two-step treatment process was recommended to enhance bamboo green colour production, fungal decay resistance, production rate of treated bamboo and prevent sludge formation in treatment solution. In the treatment process, the bamboo was pressure-treated until refusal point with 4% chromated copper arsenate-3 to achieve required preservative retention and dipped into 4% chromated copper arsenate-3 for 2 days to produce green colour on the bamboo surface. The chromated copper arsenate-treated bamboo samples had outstanding colour fastness and mildew resistance after 24 months of outdoor weathering. The fixation and leaching tests demonstrated that the total amount of preservative components leached from the chromated copper arsenate-treated bamboo samples was high to raise safety issues and caused environmental problem during the use of treated bamboo in the field.
Why Does Populism Have a Future?
Authors:   Sofia University “St. Kliment Ohridski”, Sofia, Bulgaria, Glouhtcheva Tania
Published: January 2022

The following research aims to present Populism as a phenomenon and the reasons why it has a future all over the world. The XXI - st century is also known as the "Populist era" (Cas Mudde). Both the left and the right have nothing more to offer and give the people who want something new. The change should also give them security. Populism has a future because it is not an ideology. It "borrows" the most appropriate from the left and the right ideologies and "adjusts" them to people’s problems and gives solutions. Populism is a global phenomenon. Today we are witnessing the 4-th wave which is spreading all over the world. The former 3 waves have been mainly in Latin America, the place which is also considered its cradle, as Ernesto Laclua argues. Many political scientists such as Cas Mudde, have warned about the threat of the rising Populism, at the beginning of the century, but nobody paid attention. Why is Populism becoming more and more popular? The main reason is that it constantly changes. It’s different in every country and always has "the right solutions" to the different problems of the different societies. Hence, it aims not only those who don’t sympathize any political party, but also those who are disappointed, have doubts and those who don’t feel represented. Secondly, the populist leader is always close to the people: he dresses like them, understands their problems, walks among the people and doesn’t have bodyguards. He doesn’t need to say "I am one of you!" because it is obvious. The political scientists talk about "Left Populism" and "Right Populism". The first one is typical for countries with serious social problems – mainly in Latin America. Whereas the second type characterizes the countries with well-developed economies – in Western Europe and the USA. There are not many researches made about the Populism in Bulgaria. Political scientists start using the word in the last decade and it is applicable to all parties. Georgi Karasimeonov and Daniel Smilov, argue that Simeon Saxe-Coburg-Gotha is the first Bulgarian populist leader. Even after his government, the people still look for someone "to save" them, which only proves that Populism is not over and it is something useful because it brings hope. The used methods are: sociological research, taking interviews, analyzing data and deduction. The paper contains the author’s personal researches, made in the University of Sao Paulo, in Brazil Keywords: Populism, Left Populism, Right Populism, Ideology, Leader, Bulgaria, Latin America, Western Europe, USA

Moral education is a part of talent training. Based on the analysis of the current situation of moral education in colleges and universities, this study systematically analyzes the ideological and political position of local college students, their ideological and moral character, as well as moral characterization through questionnaire, interview, induction, and factor analysis; then, the existing problems in moral education are summarized as follows: the mode of moral education is rigid, students’ subjectivity and subjective initiative are disregarded, spoon-feeding is common, and a single theme is used. The form and content are not relevant to students’ life, and they do not stimulate students’ interest in learning; in addition, the effect of moral education is not evident. Based on the above problems, this study fully considers the students’ subjectivity and subjective initiative. In line with the goal of moral education in colleges and universities, the ARCS model is constructed for moral education. Through pre-class flipped classroom, problem-based learning (PBL) during classes, as well as the summary and reflection after classes, the function of moral education for self-education, self-management, self-reflection, and self-service can be realized.

Gravity Matters: Circus as a Device. An Approach on Staging the Relationship between Human Beings and Gravity
Authors: Leyton Paloma
Published: January 2022

This article aims at understanding Circus as a creative device in order to provide an alternative approach to the study of contemporary circus creation. To this effect and from a plural, multidisciplinary perspective, the article will be organised in four main parts. Justifying Circus as a device for staging the relationship between the human beings and the force of gravity; specifying why this relationship is indeed at the very core of human beings’ experience and identity matters; contextualising nouveau cirque within the evolution of artistic avant-gardes from post-modern currents to our days; and providing a series of practical examples of these first two points by studying selected works from a series of contemporary artists. Such approach evidences Circus’ aesthetics of risk as a convergence point for researches in corporeality and performativity, while allowing a parallel study on the problematic of gravity as an essential condition for human identity. From both its physical and poetic aspects, this subject evolves radically through the late 20th century to the paradigms of our present, as it is visible in the work of active artists such as Aurélien Bory, Kitsou Dubois, Maria Donata D’Urso, Chloé Moglia, Yoann Bourgeois or Inbal Ben Haim.
“Żałuję, że nie urodziłem się niedźwiedziem”. Park Tańczących Niedźwiedzi w Bułgarii
Authors: Kierwiak Zuzanna , Markiewicz Eliza
Published: January 2022

Dancing Bears Park in Belica, Bulgaria houses bears which were traditionally used by the Roma people for dancing performances across the country. This paper focuses on the narratives generated by the Park itself and the journalists writing about it. The work presents and analyzes two narratives, subordinated to the overarching discourse of transformation and focused on the Dancing Bears Park. In one of them, produced by the institution itself, the image of the Park as a refuge for animals harmed by humans dominates. The second narrative, produced mainly by cultural texts about the Park, situates the practice of bear-dancing, which is a problem and source of shame, in the context of the social positioning and attitude of Bulgarians towards the Roma living in Bulgaria. Our research is based on the method of critical discourse analysis, methodological approach associated mainly with the person of Teun van Dijk.

The white spot syndrome virus (WSSV) is a constant threat for white shrimp (L. vannamei) aquaculture since it can cause major economic losses. One of the biotechnologies that have gained relevance to prevent WSSV infections are the bio-drugs based on RNA interference (RNAi) mechanisms, which can be initiated by the exogenous application of double-stranded RNA (dsRNA) that is administrated to shrimp for blocking the expression of some viral gene. In the present work, we made a small-scale evaluation of a bio-drug (Bfvt) constructed from a specific dsRNA against the viral gene associated to orf89 from WSSV, as prophylactic treatment in L. vannamei broodstock. The Bfvt was administrated intramuscularly to shrimp broodstock from two families (B and C) with natural resistance to WSSV, which were subsequently challenged with the virus through two ways of infection (intramuscular and per os). The results show that although both families presented a similar resistance to WSSV, the administration of Bfvt decreased the viral load and increased the survival of shrimp challenged with the virus, especially those that were intramuscularly infected. We conclude that the intramuscular administration of Bfvt is efficient and viable as strategy to prevent the WSSV infection in shrimp broodstock confined to maturation.

The border as a resource – new places for tourism development. Evidence from two Carpathian tripoints
Authors: WIĘCKOWSKI MAREK
Published: January 2022

Background: The development of cross-border tourism and local resources based on the border has grooving the importance in last decencies. One of the most important tourist attractions on Polish borders are tripoints. This article seeks to discuss changes made, by reference to two border tripoints situated on the junction of Polish, Czech and Slovak borders in the Beskids Mountains and on the junction of Polish, Slovak and Ukraine borders in the Bieszczady Mountains. Material and methods: Analysis of historical, legal and statistical materials as well as cartographic analysis and fieldwork were conducted. Informal discussions and formal in-depth interviews were undertaken with tourists in each of the researched tripoints: informal interviews/discussions with 45 tourists in the tripoint between Poland, Slovakia and Czechia and informal interviews/discussions with 40 tourists in the tripoint between Poland, Slovakia and Ukraine. Results: The tourists reaching tripoints in the Carpathians argued that the places have a great potential for tourism development. They underline great symbolic meanings, possibility to visit three countries in a short time and the importance of the point which is interesting and give an opportunity to take a nice photo. The presented research also exemplifies the concept of a new tourist space beyond traditional tourist destinations. This ensured the status of the tripoint as a resource, a “discovery”, and a curiosity. Conclusions: The border tripoints give great opportunities for the development of tourism. Openness and permeability of borders can determine development on both sides of tourism related to the presence of the border, and offer an opportunity for cross-border attractions to be set up. Tripoints as emerging tourist attractions have appeared in new marketing materials and have the potential to serve as unique border attractions.

Published: January 2022

Background: The purpose of this study was to assess the effects of mental fatigue (MF) on the psychophysiological and cognitive responses and technical skills in small-sided games (SSGs) in amateur soccer players. Material and Methods: 18 soccer players played 2vs2, 3vs3, and 4vs4 SSGs under 2 different playing conditions: MF+SSGs and SSGs. The Feeling Scale (FS), Felt Arousal Scale (FAS), Visual Analogue Scale-Anxiety (VAS-A) and Motivation (MTV) were determined after each SSGs bout. A Trail-Making Test (TMT) was also determined in the beginning and at the end of each SSGs. Technical performance was continuously recorded with a camera during all SSGs. Results: The results demonstrated that MF induced higher negative psychophysiological and cognitive responses (p≤0.05, d=ranging from 0.73 to 2.78) in 2vs2 and 3vs3 SSGs compared to 4vs4 SSGs except for VAS-A and MTV responses. Furthermore, the MF intervention also induced an adverse effect on technical skills (p≤0.05, d=ranging from 0.65 to 2.50) in 2vs2 and 3vs3 SSGs compared to 4vs4 SSGs except for interception, tackle and two touches skills. Conclusions: These findings showed that MF impacted the psychophysiological and cognitive responses, and technical skills during SSGs. Coaches should take MF into account before planning SSGs.

Agar is an essential polysaccharide that has been utilized in numerous fields. Many kinds of literature have been published regarding agarolytic microorganisms’ isolation and agarases biochemical studies. In this search, a local marine agarolytic bacterium associated with marine alga Ulva lactuca surface was isolated and identified as Pseudoalteromonas sp. MHS. The agarase production was parallel to the growth of Pseudoalteromonas sp. MHS as cells displayed a lag phase (2 h), subsequently an exponential growth that prolonged till 10 h where maximum growth (OD550nm = 3.9) was achieved. The enzyme activity increased rapidly as cells increased exponentially where the maximum activity of 0.22 U/mL was achieved after 8h and remained constant till 12 h during the stationary phase of growth. Agarase production was optimized using Plackett-Burman statistical design by measuring enzyme activity as a response and the design was validated using a verification experiment; the activity of the enzyme increased from 0.22 U/mL to 0.29 U/mL. Pseudoalteromonas sp. MHS agarase was partially purified and its molecular weight (MW) was determined by SDSPAGE (15-25 kDa). Agarase showed approximately 94% of its activity at 40 °C. The enzyme stability decreased as the temperature increased; the enzyme could retain about 98, 90, 80, 75, and 60% of its activity at 20, 30, 40, 50, and 60 °C, respectively. Biomass of the red alga Pterocladia capillacea proved to be a suitable substrate for agarase production using Pseudoalteromonas sp. MHS; the enzyme activity recorded after 24 h of incubation was 0.35 U/mL compared to 0.29 U/mL from the optimized medium.

Social science researches at present emphasize the construction of relations between multiple constructs. Psychological science is no exception. Before verifying whether their hypotheses are true with a questionnaire method or experimental method, scholars will check out the hot topics of recent years and construct multiple mediating and moderating relations first. They work on scattered topics that more or less overlap with many other disciplines. In previous years, the author focused on studying the youths with poor mental health in the new era of China, observing their moral choices in the corporate environment through game theory experiments. The conclusions are usually surprising- most new-generation youths choose to maximize their self-interests from between pro-social behaviors and risk aversion.

Objectives: Objective of this study is to determine the correlation between salivary cytokine concentrations and cariogram value high (C1) and

low (C2) experience in people. In this direction, saliva cytokines showed a significant correlation with the patient’s caries experience.

Patients and Methods: Unstimulated whole saliva samples were collected from 38 appropriate populations of patients aged between 20 to

57 years old. All patients’ DMF (decay/missing/filled) values were higher than 0. Twenty-one caries activity groups (C1) and 17 caries nonactivity

groups (C2) patients were collected for this study. Procedures of the clinical evaluation were the collection of saliva samples and oral

examination. The whole saliva from 38 patients with C1 and C2 was investigated for the existence of GM-CSF, TNFα, IFN-g, IL-2, IL-4, IL-6, IL-8,

and IL-10.

Results: The study population consisted of 38 subjects with a mean age of 34.76 14.43 years. Likewise, there was a significant interaction

between salivary flow rate, S. Mutans number, number of Lactobacillus, number of meals and IL-6, a significant difference in caries activity

groups.

Conclusion: Salivary cytokines demonstrated significant interactions to caries experience of the patient.

The paper presents an overview of the seismicity of the southern part of the Russian Far East for 2020: the Amur–Primorye region, Sakhalin and Kuril-Okhotsk regions. It is based on the preliminary data from the earthquake catalogs of the Sakhalin Branch of the Federal Research Center “United Geophysical Survey of the Russian Academy of Sciences” (SB FRC UGS RAS). An analysis of the seismicity of the regions for 2020 in comparison with the previous decade is performed. Information about the earthquakes of 2020, which are the most significant and worthy of separate study, is given. These events occurred in the SB FRC UGS RAS responsibility zone: an earthquake near the Zeyskaya HPP, a deep-focus earthquake in the Tatar Strait, an earthquake at intermediate depths in the Southern Kuril Islands, a reverse fault earthquake on the bend of the Pacific lithospheric plate in the Northern Kuril Islands. According to formal indicators, the seismicity of the regions in 2020 remained within the background values, but it approached the upper limit of their range in the Kuril-Okhotsk region and in the mantle under the territory of the Sakhalin region.

The influence of the composition of the composite electrode on its electrochemical characteristics is investigated. The optimal ratio between the components of the solid-phase cathode is established: (86 % CFx: Ag2V4O11): 7 % ECA : 7 % SPE. A comparative analysis of the characteristics of solid-phase electrodes based on fluorocarbon and composite compositions ones is carried out. It is shown that the composite electrode has an increase in the average discharge potential compared to a conventional fluorocarbon one of about 0.1 V, the specific energy increases by 11.2 %, and the specific capacity increases by 7.6 %. Models of current sources with polymer electrolyte have a flatter and longer discharge curve,as well as a smaller self-discharge during storage compared to models with liquid electrolyte. Thus, when stored for four months at a temperature of 90°C, the drop in the capacity of models of cells with polymer electrolyte was at the level of measurement error, while the drop in the capacity of models with liquid electrolyte was about 15 %. Tests of models of a video capsule of a video capsule endoscopy system with an energy drive from solid-phase cells and traditional lithium-fluorocarbon cells with a liquid electrolyte were carried out. It is established that solid-phase cells are superior in capacity and stability to known analogues with a liquid electrolyte.

In this work, we obtained porous materials based on Cu – Zn alloy with high permeability and developed surface. This was achieved by creating multilevel porosity in the material by a combined method that combines the use of a removable pore former and chemical etching. The effect of synthesis conditions on the structure and properties of the obtained materials is investigated. The material structure is a system of interconnected pores with a size of 300 – 400 µm, as well as pores with a size of fewer than 15 µm. On samples subjected to chemical etching, an increase in the specific surface area was observed from 0.11 to 4.12 m2/g in the case when the pore-forming agent was ammonium bicarbonate, and from 0.88 to 1.60 m2/g — when the blowing agent was potassium carbonate. The multilevel porous material had a permeability of more than 12·10–12 m2 and a porosity of 83 – 87 %. It was found that the sintering of the material is accompanied by the evaporation and condensation of zinc on the surface of the pores.
