La voluntad totalitaria del Franquismo
Authors: González Prieto Luis Aurelio
Published: June 2021

A mediados de los años sesenta del siglo pasado surge con fuerza y apoyado por el propio régimen franquista la caracterización de que el sistema político instaurado por el general Franco había sido solamente autoritario y no totalitario. Pese a los intentos de la doctrina política alineada con su defensa de eximirlo de toda veleidad totalitaria, las circunstancias políticas en las que se inscribe a finales de los años treinta y comienzos de los cuarenta son de una clara e inequívoca voluntad totalitaria. La pretensión de constituir un Estado que se debía totalizar al servicio del catolicismo era defendida por el propio general Franco y la práctica totalidad de la doctrina política que lo apoyaba. Para inscribir el Estado español de aquella época entre las realidades estatales totalitarias se desarrollaron varías teorías como: el Totalitarismo Humanista, el Totalitarismo Subjetivo, el Totalitarismo Solidarista o la de España como una Gran Potencia Espiritual Totalitaria.

The paper proposes a model of a predator evolution in a community of two species which interact as a predator and a prey. We assume that the predator's fitness depends on food supplies. The model was examined analytically and numerically. It is shown that the fixed-point stability loss can go according to both, the Neimark-Sacker scenario and the period doubling bifurcation. The model reveals bistability and multistability; therefore, initial conditions determine which of the coexisting dynamic modes will be attracting. It is demonstrated that different dynamic modes can be implemented depending on the prey abundance.

The Loss and Reacquisition of Caffa: The Status of the Geno­ese Entrepôt within the Borders of the Golden Horde
Authors:   Marjani Institute of History of Tatarstan Academy of Sciences, Hautala Roman ,   University of Oulu
Published: June 2021

Research objectives: To analyze both the circumstances of the armed conflict of Genoese Caffa with the troops of the Golden Horde ruler, Toqta Khan, in 1307–1308, which ended with the temporary expulsion of Italian merchants from the Jöchid territory, and their return to Caffa under Toqta’s nephew and successor, Özbeg Khan. Research materials: The information on the conflict between the Genoese and Toqta Khan is contained in an anonymous continuation of the chronicle of the Genoese Archbishop, Jacopo da Varagine, dating to the middle of the fourteenth century; in the chronicles of the Mamluk authors, Baybars al-Mansuri and al-Nuwayri; and in a local Greek source, namely the Sugdeian Synaxarion. In turn, sources that provide information about the circumstances and conditions of the return of the Genoese are much more diverse. Of course, the most important details are contained in the official documents of Genoa and Caffa. Valuable details are also contained in the missionary sources of the Franciscans preaching the gospel within the Golden Horde. For its part, the Franciscan information is useful to compare with that found in Rus’ian sources regarding the relations of Catholic and Orthodox prelates with the Khan of the Golden Horde. Research novelty: This study highlights that the use of Franciscan sources appears to be extremely useful to complement the analysis of the relationship of the Genoese entrepôt of Caffa with the local authorities. Research results: An analysis of the conflict between the Genoese and the local authorities, along with the conditions of their return negotiated with the new Khan of the Golden Horde, reveals the obvious fact that Caffa, having undoubtedly grown in the Golden Horde period due to the activities of the Genoese immigrants, had to recognize its submission to the Jöchid rulers from its very foundation. The Genoese administration likewise recognized this dependence during the restoration of Caffa in the first years of Özbeg Khan’s reign.
The Bulgar and Golden Horde’s Theologians and Theological Sources through the Prism of Sh. Marjani’s “Mustafad al-akhbar…”
Authors:   Marjani Institute of History of Tatarstan Academy of Sciences, Adygamov Ramil K.
Published: June 2021

Research objectives: The “Mustafad al-akhbar…” is one of the earliest and most important works on the history of the Bulgars and their descendants – the Tatars. After evaluating this source, we can rightly say that it is the first attempt at a scholarly description and analysis of the history of the Bulgars and Tatars. To achieve this purpose, Sh. Marjani used a large array of different sources, among which a special place was occupied by theological sources. In revealing religious life, the theologian used mainly written sources, but he did not limit himself to quoting them. The presentation of these texts is accompanied by Sh. Marjnani’s analysis of the information’s reliability. The author compares the facts and makes reasonable conclusions about the biographies of theologians, as well as the content of their works. The purpose of the study is to identify the authors’ names and the titles of their theological works that Sh. Marjani used in the first volume of the mentioned work. Research materials: The source basis of the study was the first volume of the “Mustafad al-akhbar…” by Sh. Marjani, as well as reference works by Muslim biographers. Throughout the study, the author used the methods of analysis and synthesis, as well as the historical and comparative method. Research results: This study established the titles of the theological treatises to which Sh. Marjani referred in the first volume of the “Mustafad al-akhbar…”, their content, the names of their authors, and years of their deaths. The study of the personalities of theolo­gians and their works has allowed for a division of them into respective Bulgar and Golden Horde periods. However, it should be noted that Sh. Marjani partly goes beyond these pe­riods and mentions some theologians who lived after the conquest of the Kazan Khanate in 1552. Research novelty: The author described, for the first time ever, the titles and topics of theological works mentioned in the first volume of the “Mustafad al-akhbar…”. Also, he identified the names of their authors and divided the works according to a historical prin­ciple into the works of the Bulgar and Golden Horde periods.
Ivan IV’s Postponement of the Assault on Kazan: A Manifestation of the Allegorical Nature of Medieval Texts and Real Behavioral Practice
Authors:   Marjani Institute of History of Tatarstan Academy of Sciences, Aksanov Anvar V.
Published: June 2021

Research objectives: To study the semantics of textual reports about Ivan IV’s postponing of the assault on Kazan. Research materials: Chronicles and tales, Razriad books, diplomatic documents, act materials, foreign works about Muscovy, materials from the correspondence of Ivan IV with A.M. Kurbsky, etc. Results and novelty of the research: The author identified allegorical elements in the description of Ivan IV’s behavior during the assault on Kazan on October 2, 1552 by comparing this description with similar reports about the Stand on the Ugra in 1480 and the Battle of Kulikovo in 1380. Importantly, the reliability of the reports of official sources about Ivan IV’s postponement of his riding out to join the troops is confirmed by the account of A.M. Kurbsky, who explained the motives of the tsar’s action in a different way. The memories of A.M. Kurbsky, indicating the manifestation of pathological fear behind the actions of Ivan IV, are confirmed by the analysis of the tsar’s behavior during the Oprichnina, when his personal qualities were expressed more vividly in source material. It is concluded that Ivan IV’s excessive categorism in his confessional policy became a serious obstacle to the incorporation of the peoples of the Volga region into the Muscovite State. Consequently, Ivan IV played a significant, but mostly negative, role in the assault on Kazan in 1552 as well as during the process of incorporating the peoples of the Volga region into Russia.
The Kuchum Settlement: The Capital of Siberia or a Historical Myth (Archaeological Facts and Historical Assumptions)
Authors:   Tobolsk complex scientific station of the Ural Branch of the Russian Academy of Scien­ces, Adamov Aleksandr A.
Published: June 2021

Research objectives: The article scrutinizes the arguments challenging the urban status of the Kuchum settlement (Isker), the capital of the Siberian Khanate. The author analyzes the available data on the vicinity, population, trading, and craft production of this capital. Research materials: The main sources are materials obtained during archaeological research in the ancient settlement in the twentieth and twenty-first century, as well as artifacts collected on the shallows of the Irtysh River from the destroyed cultural layer of the mo­nument since the 1880s. The cartographic materials of S.U. Remezov, V. Filimonov, and V.N. Pignatti were also used in the study. Results and novelty of the research: An analysis of the available data showed that the area of the monument reached at least 2.6 hectares by the late fifteenth century. In addition, archaeological research by A.P. Zykov and the author revealed a complex multi-level fortification system aimed at defending the capital of the Siberian Khanate. The artifacts found in 2019 suggest the presence of oversize brick structures in the capital. Such artifacts prove the important role of Isker as the center of trade located on the most convenient route which connected Central Asia, China, Eastern Europe, and the taiga regions of Western Siberia. The population of the settlement widely used silver and copper coins in trading. The collected data show that blacksmiths, casters, jewelers, tailors, and tanners lived and worked in Isker. A huge cultural layer, rich in artifacts, of the Kuchum settlement could be formed only by a fairly large population by Siberian standards, consisting of the khan’s family and its servants, close members of the nobility, Muslim clergy, warriors, merchants, and artisans. The total available data allows us to consider Isker as the political, commercial, craft, and religious center of the Siberian Tatars.

Abarcando conflitos, negociações e interesses múltiplos, reuniam agentes diversos (índios, lideranças indígenas, jesuítas, autoridades coloniais, elites locais, entreoutros), mas, no que se refere à estabilidade da comunidade, dependiam fundamentalmente da concórdia entre os oficiais indígenas coloniais e os demais índios.
Top institutional investors and accounting comparability
Authors: Le Thien
Published: June 2021

This study examines the relation between firm pair’s sharing of a top institutional investor (i.e., an institutional investor with the largest shareholding) and accounting comparability. Using data from Compustat, CRSP, and Thompson Reuters over the 1993–2017 period, the study finds that firm pairs that share the top institutional investor exhibit higher accounting comparability than other firm pairs. In addition, firm pairs whose top institutional investors are monitoring institutions (regardless of whether they are the same institutions) exhibit greater comparability than other firm pairs whose top institutional investors are non-monitoring institutions. Collectively, the study contributes to existing research on accounting comparability and large institutional investors by showing that the sharing of top institutional investors is an important determinant of accounting comparability

The outcomes of surgery for Acute Stanford type A aortic dissection
(ATAAD) have significantly improved in recent decades due to advances in
surgical techniques and, surgical adhesives such as BioGlue. However,
this convenient material can sometimes cause complications such as
thrombotic embolism and pseudoaneurysm. Here, we present the case of a
61-year-old male with ATAAD who successfully underwent total arch
replacement. Five days after the surgery, he collapsed due to right
hemiplegia. We immediately performed cerebral thrombectomy and removed
the thrombotic embolus caused by BioGlue, which was used to obliterate
the false lumen of the dissected aorta during ATAAD repair.
Service and education: the Royal Hungarian Bodyguard as a cultural institution in eighteenth-century Vienna
Authors: Kökenyesi Zsolt
Published: June 2021

The Royal Hungarian Bodyguard, founded in 1760, was the first guard unit at the Viennese court to be recruited on a territorial basis and exclusively from noblemen. The establishment of the Guard served three purposes: to significantly increase the presence of Hungarians at court, to represent the monarch (the power of the sovereign) and the Hungarian estates, and to provide a cultural space for young Hungarian noblemen. For them, the Guard became an aid in building patron-client relations and in orientation in the court environment, which was especially important for the natives of eastern Hungary and the Principality of Transylvania as well as for Protestant noblemen. The article examines the role of the Guard in expanding the cultural horizons of young Hungarian nobles. The purpose of the paper is to present the role of the guard as an instrument of education and acculturation of Hungarian nobles against the background of well-known and recently discovered sources, such as guard establishment proposals, school register books and so forth, and to awaken interest of international research to the importance of this special institution. At the beginning of the article, an overview of the early proposals of the establishment of the Guard is given, then the principles of its operation are described, and finally, several examples are given to illustrate the role of the Guard in the careers of Hungarian magnates and noblemen.
“I have to wait and look around”: George Fedotov’s letters from New Haven to his wife, 1941
Authors: Antoshchenko Aleksandr V.
Published: June 2021

The letters of the well-known émigré historian and essayist are published. The letters are stored in the Bakhmeteff archive of Russian and East European culture at Columbia University. In the introduction, the publisher shows the assistance rendered to G. Fedotov by the well-known figures of the Russian diaspora in the United States and characterizes the importance of the correspondence for study of how he was looking for his place in the American academic community. The historian hoped to find it due to the invitation to attend the meetings of the Theological Discussion Group. Particular attention is paid to G. Fedotov’s critical understanding of the intellectual heritage of his former colleague, Fr. S. Bulgakov, caused by the need to deliver lectures at Divinity School. The consequences of this were reflected in The Russian Religious Mind, the final work of the historian, in which he criticized pagan hylozoism found in Kievan Christianity, and negatively assessed the Byzantine influence. The text of the letters is presented in accordance with the present-day spelling rules and accompanied with the necessary commentary.
COLOR IDENTIFICATIONS OF THE ALTAYS MYTHOLOGICAL DISCOURSE
Authors: Ойноткинова Надежда Романовна
Published: June 2021

Аннотация: В статье впервые анализируются цветообозначения в мифологическом дискурсе алтайцев. На материале фольклорных текстов — мифов, легенд, сказаний, шаманских текстов — выявлены характерные для мифов базовые традиционные цветообозначения. Цветообозначения рассматриваются как образные признаки мифологических концептов, в семантике которых лежат древние архетипы, возникшие в языке в результате ассоциативно-метафорического переноса.

The paper first considers the specifics of color designations in the Altai mythological discourse. The factual material of the research was published and unpublished folklore texts, in particular, myths, legends, tales, shamanistic campaigns in the Altai language. The color code is important in the conceptualization of the mythological picture of Altaians. The national-cultural specificity of color designations in the mythological discourse is due to their compatibility with concepts-nominations, designating various objects and phenomena of the invisible world. Color designations can be the first component of naming the various names of supernatural beings, deities, spirits, or their clothes. The basic colors revealed in the traditional mythological picture of Altaians — ak “white”, kara “black”, kyzyl “red”, sary “yellow”, kÿreң “brown”, kök “blue” and jazhyl “green” — in the conceptualization of mythological, mythical images, objects of the unreal (invisible) world on the basis of their deepest archetypal signs that arose as a result of associative-metaphorical transfer. In combination with mythological concepts related to the Upper World, white is a sign of divine purity, holiness, blue is a sign of heaven, green is a sign of greenery and lighted sky, red and yellow are a sign of the shining sun. In combination with the mythological images of the Lower World, black as the antipode of white symbolizes darkness, death, red symbolizes blood, hellish hell, yellow means withering, disease, evil, blue means cold, ice, water, green — dim light in darkness. When mythological archetypes were refracted into the system of folk ethics, the transformation of the signs “light — dark” into the signs “good — evil” occurred. In addition to the color code, the zoomorphic code of the Altai culture is used in the conceptualization and structuring of the mythological other world, in the modeling of its geographical landscape and the conceptualization of the world.

University for Career Construction: Expectations and Realities
Authors: Kurt Türker , Fidan Tuncer
Published: June 2021

he aim of this study is to reveal how higher education affects university students' career building processes based on the opinions of students at a state university. In line with this aim, students' opinions regarding how they chose their departments/programs, to what extent their expectations from their departments were satisfied and how they thought university education would affect their future careers were asked. 79 students studying in four faculties of a state university in Ankara participated in the study. The study was designed as a phenomenological qualitative study in which the data were obtained through a written interview form. The data were then analyzed through directed content analysis technique. The findings indicated that most of the participants made their department choices after a short decision-making period (within a few months) before taking the university entrance exam. Therefore, department choice was found to be predominantly a haphazard and even accidental process. The participants reported that their expectations were not met due to the fact that their university courses were largely theory-based, their practice and internship opportunities were too limited, and the social activities and career opportunities offered by their university were insufficient. Some participants expected positive outcomes while some had negative ones. Based on these findings, higher education institutions are suggested to develop policies to ensure graduate employability by decreasing the mismatches between student expectations, labor market demands, and what they can offer their students.

Testing The Rational Expectations Hypothesis: An Emprical Evidence From Turkey
Authors: YILDIZ Ümit , GÜNSOY Bülent
Published: June 2021

The rational expectations hypothesis suggests that economic agents make accurate forecasts about the future using all available information effectively. According to the hypothesis, even if the economic agents make incorrect estimates, they shape the expectations for correcting the error made using the available information and do not make systematic errors.

In this study, the validity of the rational expectations hypothesis for Turkey, using expectations of the inflation rates, is tested. In this context, it is examined whether the expectations are rational or not by examining the unbiasedness and the efficiency of the expectations about the price. According to results, while the efficiency hypothesis is accepted for the expectations of inflation, the unbiasedness for expectations is rejected in the study. This means that although the current information is being used, economic agents can not make the accurate forecasts. Thus, the rational expectations hypothesis for inlation expectations for Turkey is rejected. However, results also show that although the expectations are biased, professional forecasters take into account many variables while forecasting the inflation. This implies that policies can be partially effective if expectations are taken into account in the implementation of economic policies.
Ultimate Strength of Parabolic Concrete Arches
Authors:   Islamic University, Al-kuaity Adnan
Published: June 2021

This investigation is aimed to present a simple analytical approach for predicting the ultimate strength of concrete arch using theory of plasticity. Six models of two-hinged parabolic concrete arches with and without steel reinforcement were tested under concentrated load. The observed behavior of cracking strength and collapse load of the arches tested were compared with those predicted by the analytical procedure proposed here. The arches tested were un-reinforced concrete, lightly reinforced concrete, and concrete with filing iron respectively. A Good agreement is found between the proposed analysis and test results. Tests have shown that the collapse of all arches was mainly due to the formation of two plastic hinges at a point of maximum bending moment which is similar to collapse mechanism adopted in this study. The use of light concentric steel reinforcement resulted into a significant increase in the ultimate load. This increase reaches up to three times of that without reinforcement. Ductility was also found to be greatly improved due to using steel reinforcement in arches. The procedure of analysis in this paper can give a simple guide for design of concrete arch.
A Simplified Method for the Analysis of Hybrid Steel and FRP RC Beams
Authors:   University of Al-Qadisiyah, Al-Thairy Haitham
Published: June 2021

This paper suggests and validates a simplified analytical method for the analysis of hybrid steel and FRP reinforced concrete beams. The proposed method determines the flexural strength of the concrete beams based on strain compatibility and force equilibrium of the beam section under pure bending moment. The suggested method was validated against different experimental test results with very reasonable agreement. Afterward, the validated method was used to conduct parametric study to investigate the effect of two important parameters on the response and failure modes of hybrid steel and FRP RC beams. The proposed method can be implemented in the analysis and design of hybrid reinforced concrete beams with different reinforcement materials.

Published: June 2021

Shatt al-Arab River is the only international navigational river in Iraq, extending from the city of Qurna to its mouth in the Arabian Gulf at the city of Al-Fao within the governorate of Basrah for a length of approximately 204 km. Its width ranges from 400 m to 2000 m and its depth ranges from 8 m to 20 m. Since many years Shatt al-Arab River suffer from scouring at the right side (Iraqi side), that is led to displace the borders between Iraq and Iran (Al- Thalweg Line) towards Iraqi territory and thus led to loss of Iraqi land to Iran. Reducing flow velocity along the Iraqi side can led to reducing or preventing erosion in the right bank. Increasing the riverbed roughness will reduce the velocity of flow and then reducing the erosion. This principle was adopted in this study. In this research, a reach of Shatt Al-Arab with a length of 2.5 km located at 34 km northern Fao city was selected to represent the study area. A small area at the upstream of the reach mentioned earlier (700 m length) was selected and called strip in order to change the bed roughness for three different heights. This scenario was simulated with full scale (prototype scale) to investigate the effect of increasing the bed roughness on the velocity pattern at river cross sections and along the reach. The simulation done by using 3D numerical modeling CFD solver (ANSYS fluent 19). For each allocated area, as increasing the roughness height (ks), the longitudinal velocity (v) decreased at the right side by about 10% to 70% and increased by about 5% to 260% at left side along the river reach.

Published: June 2021

This study aims to determine and compare the types of Vocabulary Learning Strategies (VLS) use by Malay students with high (HPML) and low proficiency (LPML) in Mandarin as a foreign language (MFL) in the Malaysia tertiary education context. This research was conducted base on a quantitative approach and it involved 330 respondents. Results from the analysis of collated quantitative data showed that the HPML used VLS at high frequency level, whereas the LPML used them at medium frequency level. Besides, the findings also revealed that the HPML students tend to use “recall the meaning of Mandarin words” strategy; whereas those from the LPML frequently used strategy such as “saying new Mandarin words repetitively”. The findings show that students from both the HPML and LPML groups rarely use “flash cards to learn new Mandarin words”. The findings of the study were also used to outline pedagogical, theoretical and methodological implications.

Learning aids are among the important elements to improve one's language skills, especially for second or foreign speakers. Past studies conducted by researchers like Fa'izah et.al (2010), Khuzaiton (2012) and others have proven that there are issues of communication among speakers of languages ​​other than English in the non-Malays in Malaysia. Based on these issues, the main objective of this study is to analyze the effectiveness of the use of PETAH learning aids on improving the communication skills of students who use it. This study uses a quantitative research method that uses a questionnaire containing 25 items aimed at the effectiveness of the use of PETAH learning aids. This questionnaire instrument was used to get feedback from respondents after they used PETAH learning aids. Data from the questionnaires were analyzed using SPSS version 21. The results showed that the majority of respondents (mean values ​​ranging from 3.35 to 4.71) agree that PETAH learning tools have improved their effectiveness in communication Malay language, especially if used continuously. In conclusion, a learning tool PETAH has a good impact on the improvement of communication skills of Malay language among non-Malays speakers in Malaysia.

Learning tenses is an uphill task for ESL (English as a Second Language) learners, especially children. One of the reasons is that grammatical structures in English are inherently different from those of the mother tongue. More often than not learners find it difficult to comprehend and apply the rules accurately for effective communication. Hence, they become frustrated and give up trying to learn the language. The main purpose of TYT is to address the said problems faced by these learners besides providing a fun, exciting and interactive environment to reinforce the rules of tenses learnt. Presently, English language games tend to focus on parts of speech and vocabulary learning but not many emphasise on tenses. TYT fills in the gap to reinforce the learning of tenses and its application in different everyday contexts. Children can learn with their peers while playing in an enjoyable setting which will promote better retention of their tenses knowledge. TYT is also useful for language educators as an alternative teaching tool to drill the rules of tenses which otherwise would be too monotonous and dry for students in the classroom.

The purpose of this study was to examine the perceptions of the lecturers of the Academy of Language Studies (APB), UiTM Cawangan Pulau Pinang (UiTMCPP) with regard to problems in writing formal letters concerning language style. Language style is a very important element in the writing of a formal letter because it can affect a recipient’s views of the sender of the letter. If the language style used is inaccurate, it may also result in misunderstandings between a sender and a recipient and may cause a program being delayed due to errors in the letter. The research method used was descriptive which involved the analysis of data from a questionnaire distributed to 30 respondents (APB UiTMCPP lecturers). The data collected was analyzed using SPSS software version 23. The findings showed that the lecturers were indeed confused about the language style of formal letter writing and that the highest percentage belonged to the item that indicated that the majority of the lecturers agreed that they were mistaken about the correct use of slogans / motto in formal letter writing. The study is expected to assist the researchers in providing a solution to facilitate the lecturers at the APB UiTMCPP in writing formal letters.

Authors: Godoi Marcos , Borges Cecilia , Ayoub Eliana
Published: June 2021

O objetivo desta pesquisa foi analisar as razões de agir de um professor de educação física em episódios de ensino que envolveram diferenças de gênero e de habilidades dos estudantes. Neste estudo de caso, foram realizadas observações e filmagem de onze aulas da turma do 6º ano e entrevistas de autoconfrontação com o professor. Nos nove episódios de ensino analisados, notou-se que, nas aulas deste professor, existe uma ênfase na adaptação das regras dos esportes e dos jogos; ele propõe uma pontuação maior para o gol das meninas no handebol e no futsal; alterna os gêneros na escolha das equipes e os últimos estudantes escolhem suas equipes e qual equipe começa jogando; valoriza a resolução de problemas e as estratégias de jogo; realiza provas coletivas no atletismo, somando a pontuação de todos os membros da equipe; adapta a distância do saque do voleibol de acordo com o nível de habilidade dos estudantes; no jogo de queimada, as meninas podem queimar meninas e meninos e os meninos só podem queimar meninos. A razão de agir deste professor revela seu esforço para equilibrar as relações entre meninos e meninas, mais ou menos habilidosos, possibilitando a vivência de experiências de equidade de gênero nas aulas.
Tutela provisória no CPC 2015

A partir das modificações introduzidas no processo civil brasileiro pelo CPC/2015, que produziram acalorados debates doutrinários, principalmente, com relação à estabilização da tutela, surgiu o seguinte questionamento: Quais são as divergências existentes na doutrina e jurisprudência com relação à decisão que determina a estabilização da tutela antecipada requerida em caráter antecedente? Para a realização da pesquisa utiliza-se o método dedutivo, partindo da teoria de base processual civil sobre tutelas provisórias, para análise do instituto da estabilização da tutela de urgência antecipada concedida em caráter antecedente. Foram utilizadas as técnicas de pesquisa bibliográfica e documental, a partir da consulta de doutrina, legislação e jurisprudência. Tem-se como objetivo principal perquirir as divergências com relação à estabilização da tutela antecipada antecedente, especificamente considerando a necessidade ou não de interposição de recurso para estabilização, bem como, a natureza jurídica da decisão que determina a estabilização da tutela. Assim, foi possível analisar os posicionamentos doutrinários acerca da divergência em razão do cabimento ou não do recurso diante da decisão que concede a tutela antecipada antecedente, prevalecendo de forma majoritária o entendimento de que a contestação, sempre que impugnar a concessão da tutela antecipada antecedente impede os efeitos da estabilização. Além disso, foi apresentada a natureza jurídica da estabilização da tutela, que não faz coisa julgada, motivo pelo qual possibilita o ajuizamento de nova ação mesmo após o prazo de dois anos, para discutir o mérito, visto que este não foi analisado de forma exauriente nos autos que concedeu a tutela antecipada antecedente.

Cell migration is an essential process for wound healing, metastasis and inflammation. Focal adhesions (FA) are local regions of plasma membrane consisting of multiprotein complexes providing adhesive contact between the cell and the extracellular matrix (ECM). FA turnover regulates different signalling pathways implicated in various cellular responses (e.g. cell migration). Endocytosis, specifically the dynamin and clathrin pathways, is known to regulate cell migration by modulating FA dynamics. In this study, we investigated whether NO activity regulates cell migration, FA dynamics and early endosome trafficking in MDA-MB-231 cells. The assessment of cell migration showed a slowing down of cell migration and an increased duration of FA turnover in cells treated with inhibitors of NO synthase (NOS) such as L-NAME or 1400W. In addition, these treatments were found to exhibit no effect on transferrin and dextran uptake mediated by endocytosis and micropinocytosis, respectively. The number of early endosome antigen 1 (EEA1)-positive endosomes was reduced while their sizes were found to increase in cells treated with L-NAME or 1400W. In contrast, these inhibitors did not affect the number nor the size of Rab5-positive endosomes. Furthermore, we demonstrated that EEA1, endothelial NO synthase (eNOS) and inducible NO synthase (iNOS) were colocalised. Using the biotin switch assay followed by western blot, we showed that early endosome proteins such as APPL1, EEA1, Rab5 were found to be S-nitrosylated. These results were further supported by the sequence analysis performed with the GPS-SNO algorithm which predicted the S-nitrosylation of these endosomal proteins. Taken together, our findings suggest that NO might be involved in cell migration and FA turnover through early endosome trafficking in MDA-MB-231 cells.

Stem cells are an important subject of research, and are increasingly used in the treatment of various diseases. Due to the development of advanced in vitro techniques, they have become an integral part of modern medicine. The sources of human stem cells are primarily bone marrow and adipose tissue, although non – embryonic stem cells are also scattered throughout the body. Notably, recent research has focused on stem cells found in the oral cavity, both in the dental pulp and oral mucosa. Furthermore, isolation of stem cells from umbilical cord blood is also becoming increasingly popular, while wharton’s jelly and amniotic fluid also seem to be an interesting source of stem cells. The safety and efficacy of stem cells use can be established by animal studies, which are a key element of preclinical research. Mouse, rat and pig models allow for testing of stem cell therapies. Recent studies primarily use mesenchymal stem cells such as mouse – adipose derived mesenchymal stem cells and mouse and rat hematopoietic stem cells. Great hope for future therapies is the use of bioengineering to program cells into induced stem cells, which have the biggest ability for differentiation and transdifferentiation, which carries no risk of teratogenesis. Stem cells are used in many areas of medicine, especially in regenerative medicine, with a growing interest in orthopedics and in the treatment of heart failure. Mesenchymal stem cells are the most used stem cell type, which despite their limited ability to differentiate, give great therapeutic results, mainly due to their immunomodulating effect. Recent studies have even shown that the use of mesenchymal stem cells may be useful in the treatment of COVID-19. Moreover, Research on the use of mesenchymal stem cells in the treatment of Crohn’s disease, acute-graft-versus-host disease and type I diabetes are also promising. The aim of the current review is to present and systematize current knowledge about stem cells, their use and related in vitro research.
