Authors: Pozdnyakov Dmitry I. , Zolotych Denis S. , Larsky Michael V. 
Published: April 2021

Abstract

The aim of the study. To evaluate the effect of succinic acid derivatives on changes of mitochondrial function in rats under cerebral ischemia conditions.

Materials and methods. In this work, the effect of succinic acid, ethylmethylhydroxypyridine succinate, and acetylaminosuccinic acid at doses of 50 mg/kg, 100 mg/kg, and 200 mg/kg (per os) on the change of the neuronal mitochondria function was studied. Cerebral ischemia was reproduced by the Tamura method. The following parameters were evaluated: changes in aerobic/anaerobic metabolism, mitochondrial membrane potential, the opening rate of the mitochondrial pore of transitional permeability and the activity of apoptotic systems.

Results. During the study, it was found that the use of the test-compounds at doses of 100 mg/kg and 200 mg/kg contributed to an increase in ATP-generating activity, as well as the maximum respiration level and respiratory capacity, while accompanied by a decrease in the intensity of anaerobic metabolism reactions. Also, upon administration of the test succinic acid derivatives, an increase in the mitochondrial membrane potential and latent opening time of the mitochondrial pore transitional permeability were observed. Moreover, the activity of caspase-3 and apoptosis-inducing factor on groups treated by test objects at doses of 100 mg/kg and 200 mg/kg was significantly lower than that in untreated animals.

Conclusion. The studied succinic acid derivatives contribute to the restoration of mitochondrial function in cerebral ischemia conditions, while the most effective dose can be considered to be 100 mg/kg.
Evaluation of apical root resorption occurrence in orthodontic patients treated with fixed braces depending on selected clinical parameters
Authors: Ciurla Agata , Szymanska Jolanta 
Published: April 2021

Abstract
An aim of the work was analysis of the possible connections between the selected clinical parameters and external apical root resorption (EARR) in patients after orthodontic treatment.
The study comprised 101 persons, who underwent complex orthodontic treatment with the use of fixed braces (straight-arch technique).
The teeth chosen for measurement of resorption level were central and lateral incisors of mandible and maxilla, as well as maxillary first molars, which are the most susceptible to root resorption. The roots were measured on the basis of the dental radiographs taken before and at the end of treatment. The measurements were made on digital radiographs with the use of diagnostic software (Planmeca Romexis® Viewer), which allows the image filters ensure the highest precision when localizing roots end points. Proportional measurements of the chosen teeth were made with the use of Linge’s method and Linge’s method modified by Brezniak et al. For further analysis, the persons taking part in the study were divided into two groups depending on the presence of postorthodontic EARR or its lack, resulting from radiographic measurements: a control group comprising 61 patients without EARR (with 0.90 ≤ rRCR ≤ 1.00) and a study group including 40 patients with EARR (rRCR < 0.90). In statistical analysis there was used verification of statistical hypotheses based on the following tests: Pearson’s chi-squared test, Student’s t-test, Mann-Whitney U test.
On the basis of the made analyses and achieved results, it was found out that age, sex, type of skeletal malocclusion, increased overjet and overbite do not constitute risk factors for EARR occurrence. Excessive proclination of central and lateral incisors of mandible and maxilla predisposes to shortening the roots of these teeth during orthodontic treatment with fixed braces (p < 0.01).

Published: April 2021

Abstract
A cell line named BBdF-1, established from the caudal fin of hill stream fish Barilius bendelisis, has been subcultured for more than 52 passages and is being maintained in L-15 media containing 20% FBS. Species origin of the cell line was confirmed using amplification of partial region of 16S and COI mitochondrial gene sequences. The optimum temperature for growth of BBdF-1 cell line was found to be 28°C. Karyotyping revealed diploid chromosome number as 50. Cells exhibited strong binding for cytokeratin marker and thus were found to be epithelial-like. Strong green fluorescence was observed in BBdF-1 cells transfected with phrGFP-II-N vector, indicating its suitability for utilization in gene expression and manipulation studies. Successful assessment of cytotoxicity of two heavy metals, viz. mercury and chromium, was performed. The cell line can serve as a useful resource material for early toxicity screening of pesticides/pollutant and gene expression.
Introduction of Invasive Peacock Bass (Cichla Spp.), Its Rapid Distribution and Future Impact on Freshwater Ecosystem in Malaysia
Authors: Khaleel Aliyu Garba , Ismail Norshida , Ahmad-Syazni Kamarudin 
Published: April 2021

Abstract
Malaysia is recognised among the mega-diversity countries with the abundance of various freshwater species. Malaysian freshwater biodiversity is under threat after the introduction of an invasive peacock bass. The presence of this predator could challenge the coexistence of the native species. In the current review, the most important aspects regarding peacock bass threats to the biodiversity future of local species are addressed. Four non-native species of peacock bass are presently recognised in Malaysia. To date, the peacock bass species expand to all parts of Peninsular Malaysia with no records yet found in Kelantan and Borneo. Invasion success is more susceptible in Malaysian lakes (84.38%) compared to the dams, rivers and reservoirs. The mode of rapid expansion of this species is highly connected to the sport fishing and anglers. A propagule pressure, favourable habitat, prey abundance and feeding behaviours are responsible factors for the successful establishment of this species in Malaysia. The species are generalist feeders and piscivorous in nature. It is difficult to eradicate peacock bass since it provides physical jobs (recreation and tourism). However, the damage the species will cause in future is unpredictable. At this point, proper management of this species must be implemented to reduce its population. This could be achieved through updating checklists of freshwater bodies, improving monitoring systems and public awareness.
Prototype Theory in the Judicial Practice of the Court of Justice of the European Union. A Case Study
Authors: Zeifert Mateusz 
Published: April 2021

AbstractPrototype theory is a semantic theory according to which the membership of conceptual categories is based not on a list of criterial features, but rather on the similarity to the most representative member of the category. Consequently, conceptual categories may lack classical definitions and rigid boundaries. This article supports the claims, already made by other scholars working in the field, that prototype theory may greatly augment our understanding of legal (i.e. statutory, judicial) interpretation. Legal provisions are traditionally written as classical definitions, but they are rarely applied that way. Statutory concepts tend to be interpreted with a great deal of flexibility, using a wide array of extra-textual factors. This is especially true for the case law of the Court of Justice of the European Union, which has to deal with the challenges of the multilingual, supranational law of the European Union.
Politica Prozei Fracturiste
Authors: Bâlici Mihnea 
Published: April 2021

Abstract
This paper is aiming to analyze the prose of the early 2000s’ young authors from an ideological and political point of view. Fracturism was a literary movement with anarchist and insurgent purposes, but the nature of their values was not clarified by the local literary criticism. This thesis suggests a redefinition of the anti-systemic attitude proposed by the Fracturists. Also, another objective is to clarify the relationship of Fracturist prose to the aesthetics’ domain. In this sense, inconsistencies can be observed between the anti-postmodernist obsession of “The Fracturist Manifesto” and the literary works themselves. Moreover, the subcultural themes as used by the young prose writers become a means of self-promotion in the Romanian literary field from post-Communism.
Lucian Blaga Și B. Fundoianu -Ipostaze Antagonice În Cadrul „Expresionismului Românesc”
Authors: Pop Ionucu 
Published: April 2021

Abstract
The goal of the following paper is to shed more light unto the similarities and the particularities that the works of Lucian Blaga and B. Fundoianu reveal in relation to Expressionism, a current often mentioned in order to catherogirse the two poets. Even though one cannot put the finger on a legitimate Expressionist poetic movement in Romanian culture without a certain ammount of exaggeration, the poetry of the aforementioned figures is undeniably compatible with the current originated from Germany. As I will try to prove, Lucian Blaga and B. Fundoianu can be seen as antagonistic instances in this context, but ultimately revealing a shared expressionist substance upon which the most divergent attitudes are bestowed.
Calea (Din)Spre Eden. Motive Biblice În Lirica Blagiană
Authors: Anca Rusu 
Published: April 2021

Abstract
The following paper revolves around the concept of biblical motifs, legends and a series of analyses that occur because of their complex and stately nature. Concerning several aspects regarding the similarities between Blaga’s poetry and biblical myths, this study reflects Blaga’s confrontation with God and an analysis of how he invokes God in his poems. Poems like „Paradis în destrămare”, „Bunăvestire”, „Întâia duminică”, „Lacrimile”, „Ioan se sfâşie în pustie”, „Pe ape”, „Balada fiului pierdut” allowed Blaga to create genuine artistic imagery with a very penetrating content, loaded with biblical motifs.
Transvalorizări Hipertextuale În Palimpsestul Narativ Sara De Ștefan Agopian
Authors: Barb Andreea Ana-Maria 
Published: April 2021

Abstract
In this paper, I will examine the novel Sara, published by Stefan Agopian in 1987. The novel is a rewriting of the Book of Tobit, from the Old Testament, and is preceded by another novel written by the prose writer on the same biblical theme, entitled Tobit. I will approach the work from the perspective the overvaluation that certain notions suffer, in the transition from the Bible to its narrative Agopian. Transvalorization is a literary phenomenon discussed by G. Genette in his study, Palimpsestes (1982), but my method is not entirely faithful to the narrator.
The Use of the Past Tenses in European Portuguese by Slovene Students: The Causes of Possible Deviations
Authors: Medvedšek Mojca , Müller Blažka 
Published: April 2021

Abstract
The analysis presented in this article aims to ascertain what conditions of use imply deviations in the use of the Past tenses in European Portuguese (PPS, PPC, PI, PMQC) by Slovene learners of Portuguese, A2-B1 level (QECRL), trying to find explanations for its occurrence. The analysis shows the contrast between European Portuguese and Slovenian language in the domain of the Past tenses in terms of tense and aspect, describes the most frequent and evident deviations in a corpus, consisting of the various genres of texts, worksheets, completed by the students. Several presumptions were verified in the qualitative analysis. Among them, the deviations are in most cases due to the fact that in the sphere of the past, the Slovene language is operating with only one paradigm of the past sphere, the preteklik (Past tense), which is supposed to mark all the temporal and aspectual nuances of four Portuguese past tenses of the Indicative. The article tries to underline the different way of marking time and aspect in the respective languages and therefore the students’ difficulties in the perception of temporal and aspectual perfect / imperfect conceptualization.
Lexical Creativity – A Salient Phenomenon in Current Romanian TV and Online Journalism
Authors: Sporiş Valerica 
Published: April 2021

Abstract
The article aims to examine an aspect pertaining to lexical neology, i.e. the lexical creativity as reflected in recent TV and online journalism. Lexical creativity articulates interdisciplinarity, the latter represents a ‛bridge‛ between the facts of language and those of style. Newly words are created by journalists to serve different purposes ranging from ludic, spontaneous, occasional to deliberate, conscious. Lexical creativity is influenced by different factors such as: analogy, imitation, calque, subjectivity, sensitiveness, context, etc.
The language of the media is characterized by dynamics, novelty and accessibility. Through their novelty, words contribute to an enrichment of expressiveness. The newly coined structures are often artificial, the examples analysed in our paper are created by small groups of journalists or by one journalist. The journalists’ intention is to impress, to draw the audience’s attention.
I chose to explore the phenomenon of affixation and I selected as lexical bases some neologisms recently borrowed into Romanian from other languages. The corpus comprises recent examples selected by the author from Romanian TV and online journalism, where the phenomenon of lexical creativity is highly displayed. I chose the transcription of new words in accordance with the phonetic-phonological principle specific to the Romanian language and with the current rules pertaining to plurals forms and use of articles.

Creativity and Intercultural Experiences: The Impact of University International Exchanges
Authors: De Prada Elena , Mareque Mercedes , Pino-Juste Margarita 
Published: April 2021

Abstract
Based on recent findings that highlight the strong links between creativity and interculturality, we will attempt to establish a relationship between intercultural experiences and creativity within the context of international university exchanges in order to propose specific courses of action for improving these skills. The methodology used is based on a quasi-experimental design for a sample of 303 university students from a Spanish university. Data were obtained from a survey that measured creativity with two different instruments (RIBS-s and Divergent Thinking), English proficiency, and intercultural experiences abroad. Results show a strong relationship between creativity and intercultural experiences, suggesting that those students who lived abroad and in a higher number of foreign countries are more creative. Additionally, the most significant differences appear when we establish a comparison between those students who have not lived abroad and those who have done so in more countries, which contributes to highlighting the close relationship between interculturality and creativity. Of special significance is the strong link found between English proficiency and having experiences abroad, suggesting that when the level of a shared international language, English in this case, is higher, there will be more options to increase students’ creativity. Likewise, students who have a higher level of English are more creative. Designing programs for higher education students that combine and integrate foreign language skills, creativity, and interculturality appear to be essential. Thanks to foreign language skills, students will be in a better position to acquire intercultural sensitivity and improve their creativity, making their international experience a valued source of fulfilment both for their personal life and their career.
Ferry Crossing, Travelling and Change in the Northern Sudan
Authors: Kurcz Maciej 
Published: April 2021

Abstract
In the past few years, the transport infrastructure of Sudan has radically changed. New roads, transport hubs, or means of transport have had a significant impact on the culture of travelling, and many of the older institutions connected with the phenomenon are things of the past now. One of those dying out phenomena is ferry crossing on the Nile. It was not long ago that a ferry was the basic means of transport throughout the riverine area of Sudan. It was the way of transporting people and goods, both along the river and across it. Today, because of the new era of modern motorways and bridges, its time is coming to an end. What can we learn about the Sudanese travel practices from the perspective of the Nile ferry? This is a fundamental question I will provide an answer to. In the paper I refer to the field observations made in the Northern Sudan in the village of ad Ghaddar in 2013.
Specific Form of Identity among Namibian Czechs
Authors: Miškařík Pavel 
Published: April 2021

Abstract
The main goal of the paper is to explain specific ways in which the group of so-called Namibian Czechs identifies itself and how we can conceptualize their specific form of identity. For this reason, the article presents specific theoretical concepts focused on identities such as diaspora or transnational and bicultural identity. In recent years, all three of these concepts are gaining more attention, and an ever-growing number of communities are labelled as diaspora, transnational, or bicultural. Affiliation with one of those categories can potentially lead to a variety of political claims for such a group. The article aims to explain which of the concepts is best suitable for the group of Namibian Czechs, a group of fifty-six former child war refugees, who were educated and accommodated in Czechoslovakia between 1985 and 1991.
Women and Medicine: A Historical and Contemporary Study on Ghana
Authors: Adu-Gyamfi Samuel , Amakye-Boateng Kwasi , Nyaaba Ali Yakubu , Acheampong Adwoa Birago , Awuah Dennis Bafour , Oware Richard 
Published: April 2021

Abstract
Women have always been central concerning the provision of healthcare. The transitions into the modern world have been very slow for women because of how societies classify women. Starting from lay care, women provided healthcare for their family and sometimes to the members of the community in which they lived. With no formal education, women served as midwives and served in other specialised fields in medicine. They usually treated their fellow women because they saw ‘women’s medicine’ as women’s business. They were discriminated against by the opposite sex and by the church, which regarded it as a taboo to allow women to practice medicine. This study points to a Ghanaian context on how the charismas of women have made them excel in their efforts to provide healthcare for their people. The study also focused on the role of indigenous practitioners who are mostly found in the rural areas and modern practitioners who are mostly found in the peri-urban, urban areas and larger cities in Ghana.
