Published: November 2022

Glioblastoma multiforme (GBM) is one of the most aggressive and invasive tumors with poor prognosis. Despite the intensive progress in development of new diagnostic and therapeutic drugs, the 5-year survival rate of patients with GBM is less than 5-10%. Search of new targets for therapy is promising approach for glioma therapy that will help to inhibit tumor growth, as well as increase the sensitivity of cancer cells to chemotherapy. Gankyrin is an oncogenic protein and a promising target for mono- and combination therapy of gliomas (Xu Guo et al, 2020). In this work, we have shown that the mRNA level of gankyrin is increased up to 10-15 times in primary human glioblastoma lines. Also, an increased mRNA level of gankyrin is associated with a negative methylation status of the o-methyl-guanine-DNA methyltransferase (MGMT) promoter, a biomarker of increased chemoresistance of tumor cells. Inhibition of gankyrin may become a promising tool for glioma therapy and opportunity to increase sensitivity of tumor cells to anticancer drugs. For this purpose, we synthesized small interfering RNA (siRNA) to gankyrin and formulated siRNA-lipid nanoparticles by mixing siRNA and lipids using a microfluidic device, performed physicochemical characterization. We demonstrated that obtained nanoparticles can effectively inhibit mRNA level of gankyrin in human glioblastoma cells.

IMPACT OF 1,4-BENZOQUINONE DERIVATIVES ON THE ACTIVITY OF L-GALACTONE-1,4-LACTONE DEHYDROGENASE FROM ARABIDOPSIS THALIANA
Authors: Kudryashova E.V.
Published: November 2022

FAD-dependent L-galactone-1,4-lactone dehydrogenase from Arabidopsis thaliana (AtGALDH) is a plant membrane enzyme of plant origin, which is a suitable model for studying the effect of effectors on mitochondrial FAD- dependent dehydrogenases. 1,4-benzoquinone derivatives (decylubiquinone and coenzymes Q1 and Q10) are widely distributed in nature, they are electron carriers in the respiratory chain and play an important role in maintaining redox balances in the cell. The interaction of these derivatives with cell membranes is known: for example, the presence of a long hydrophobic hydrocarbon fragment in the coenzyme Q10 molecule allows the coenzyme to sink into the membranes, while decylubichnon contributes to the deterioration of mitochondrial permeability. However, the effect of decylubiquinone and coenzymes Q1 and Q10 on the AtGALDH enzyme remains unexplored. Thus, the aim of this work is to study a number of 1,4-benzoquinone derivatives (decylubiquinone and coenzymes Q1 and Q10) as AtGALDH effectors.

Authors:   West China Hospital of Sichuan University, Yang Ming , Wu Youwei , Wang Tao , Wang Wentao
Published: November 2022

Review question / Objective: Iron overload conditions is a well-established risk factor for infection of pathogens. The possible association of iron overload with infectious complications and prognosis of patients receiving transplants are not well understood. Condition being studied: Liver transplantation often represents a life-saving treatment for an increasing number of patients with end-stage liver disease. With the improvements in surgical techniques, immunosuppression strategies, and post-LT management of complications, the recipient mortality has steadily declined after LT. The survival rates were 83% at 1 year, 71% at 5 years in western countries. However, the use of immunosuppressants increased risk of infections as an adverse effect resulting in severe morbidity. Globally, infection caused by including bacteria, fungus, viruses remain one of the leading causes of morbidity and mortality among transplant recipients. Knowledge of modifiable risk factors and potentially reversible causes is essential to develop targeted preventive strategies.

Relire La Méditerranée de Braudel aujourd’hui
Authors: Crivello Maryline
Published: November 2022

Du point de vue de la recherche, plusieurs conceptions de la Méditerranée coexistent qui dépendent des questions étudiées, des finalités et, bien souvent, des héritages disciplinaires. Les frontières de la région méditerranéenne se réduisent aux rives maritimes, s’élargissent aux terres intérieures ou s’ouvrent aux interactions avec le reste du monde. Dans ce foisonnement de perceptions, l’œuvre de Fernand Braudel, parfois contestée, n’en reste pas moins un socle, attractif ou répulsif, sur lequel se régénèrent les études autour de la Méditerranée.

Défis démocratiques au sud et à l’est de la Méditerranée
Authors: Billion Didier
Published: November 2022

Les États du Sud et de l’Est de la Méditerranée souffrent fréquemment d’analyses réductrices et par trop binaires. Malgré la situation déplorable des libertés individuelles et collectives, il est impossible de sous-estimer les dynamiques des mouvements sociaux et politiques qui se développent dans la région notamment depuis 2011. Même si obstacles et défis s’y opposant sont considérables, ils demeurent cependant porteurs d’espoir. Il convient donc de décrypter les principaux enjeux politiques pour mieux évaluer les potentielles ruptures démocratiques envisageables.
La lutte contre le terrorisme dans l’espace méditerranéen
Authors: Frier Adrien
Published: November 2022

Carrefour incomparable d’échanges humains, commerciaux et culturels, l’espace méditerranéen constitue un atout incomparable pour les pays qui le bordent. La liberté qu’il offre emporte cependant son lot de vulnérabilités face à des menaces sécuritaires transnationales, notamment pour les acteurs terroristes qui s’y sont établis de manière croissante depuis le début des années 2000. Sous la pression de foyers djihadistes majeurs au Levant comme au Sahel, les pays de la région connaissent une exposition sécuritaire aux contours similaires, justifiant la mise en place de coopérations approfondies dans le cadre d’un effort partenarial, seul à même de faire de la Méditerranée un espace de sécurité commun.
Parler des bébés aux adolescents : une prévention de la violence
Authors: Golse Bernard
Published: November 2022

L’auteur relate tout d’abord l’expérience qu’il mène dans un lycée à Romilly-sur-Seine en compagnie d’une enseignante (Marie Biot) et qui consiste à aller parler des bébés aux adolescents (en classe de seconde ou de première). Cette action amène les adolescents à repenser aux bébés qu’ils furent et vise à les aider à mieux accueillir les bébés qu’ils auront peut-être un jour. Il y a donc une visée d’accompagnement des adolescents vers la parentalité mais il s’agit aussi de les aider à respecter la vie psychique sous toutes ses formes d’où une visée de prévention plus large de l’intolérance et de la violence en général. Tout ceci n’est possible qu’en raison de la grande sensibilité des adolescents à l’égard des bébés et l’auteur évoque alors un certain nombre de convergences entre le fonctionnement psychique des uns et des autres. Certaines de ces convergences sont connues de longue date, d’autres sont de connaissance plus récente dans la mesure où l’essor de la psychiatrie du bébé nous permet désormais de revisiter quelque peu cette période de l’adolescence. Toutes ces réflexions s’inscrivent sur le fond de la dynamique de l’après-coup.
Développement historique des hôpitaux de jour de santé mentale pour enfants et adolescents : le cas de l’Espagne
Authors: Cardelle-Pérez Federico , Domínguez-Santos Maria Dolores
Published: November 2022

Le développement de la psychiatrie de l’enfant et de l’adolescent se produit chronologiquement plus tard que celui de la psychiatrie de l’adulte, tout comme le développement de dispositifs spécifiques pour ces âges. C’est le cas des Hôpitaux de jour, dispositifs intermédiaires dont la France et l’Amérique du Nord ont été les pionniers, et dont l’émergence et l’expansion en Espagne a été hétérogène, inégale et avec un retard par rapport aux pays environnants. Nous avons envisagé de faire un exposé historique à ce sujet, qui fait partie d’un travail plus vaste. Il existe suffisamment de preuves pour recommander la mise en œuvre de programmes spécifiques de santé mentale pour les enfants et les adolescents, tels que l’hôpital de jour, qui ont un impact favorable sur la santé mentale des patients accueillis, garantissant des prestations efficaces, de qualité et équitables au sein du système national de santé, avec une attention particulière aux patients atteints de troubles mentaux graves. De toute façon, les hôpitaux de jour pour enfants et adolescents sont une réalité de plus en plus étendue grâce à la décision, l’effort et la ténacité des professionnels de la santé mentale des enfants et des adolescents, qui ont compris et se sont adaptés aux besoins de leurs patients.
Comparison and application of top and bottom air decks to improve blasting operations
Authors: Monjezi Masoud , Amiri Hamed , Seyed Mousavi Mir Naser , Hamidi Jafar Khademi , Khandelwal Manoj
Published: November 2022

The blasting operation is an integral part of mines, and it is still being used as the most economical tool to fragment and displace rock mass. Appropriate blast optimization alleviates undesirable side effects, such as ground vibration, air blasts and flyrock, and it and enhances rock fragmentation. Blast optimization can also be effective in reducing the overall mining cost. One way of reducing blasting side effects is to use deck charges instead of continuous ones. The location of the deck(s) is still considered an unanswered question for many researchers. In this study, an investigation was carried out to find an appropriate air deck position(s) within the blast hole. For this, air decks were placed at three different positions (top, middle and bottom) within a blast hole at Cheshmeh-Parvar gypsum and Chah-Gaz iron ore mines to understand and evaluate air deck location impact on blast fragmentation and blast nuisances. The results were compared based on the existing blasting practices at both mines, as well as the air-deck blasting results. The results obtained from the blasting were very satisfactory; it was found that charging with a top air deck, as compared to current blasting practices, causes a decrement in the specific charge, as well as a decrement of 38% in the back break and 50% in flyrock; the average size of fragments obtained from blasting was increased by 26%. Thus, it can be said that the top air deck is more advantageous than the bottom air deck in terms of reducing undesired blasting consequences.
An evaluation of quantitative easing effectiveness based on out-of-sample forecasts
Authors: Kirikos Dimitris G.
Published: November 2022

A line of defense of quantitative easing (QE) policies has been developed around empirical evidence that time series models do not predict long-term asset prices and yields as well as naive random walk forecasts, implying that predictions of price reversals cannot be profitable and, therefore, that QE effects are not reversed. However, in this work we present evidence that for the Eurozone, Sweden, and the UK, which have pursued QE interventions, a random walk does not beat a Markov switching regimes model in out-of-sample forecasting and, at the same time, the switching process provides additional information regarding the likelihood of price reversals, thus inducing market participants to offset the effects of QE interventions whenever they perceive unconventional monetary policy regimes as temporary.

Published: November 2022

The main objective of the study was to assess the influence of asset quality on the financial performance of tier IV commercial banks in Kenya. The study was guided by the scientific theory of management, Transaction Cost theory and Contingency theory. This study employed a longitudinal research design. The target population was 13 tier IV commercial banks in Kenya as at 2022 from the Central Bank of Kenya’s website. Panel data was analyzed using STATA. Pearson’s product-moment correlation coefficient depicted r = -0.4306, a p-value of 0.0000 which is significant for asset quality. The regression coefficient was -0.14, a p-value of 0.013, for asset quality (AQ) and financial performance (ROE) at a 5% level of significance. These results indicate that Asset Quality had a significant influence on financial performance. It was recommended that commercial banks should use their assets efficiently and effectively to yield optimum results.

RELATIONSHIP BETWEEN PROPERTY TYPE-LOCATION DIVERSIFICATION AND PERFORMANCE OF REAL ESTATE INVESTMENT TRUSTS IN KENYA
Authors: Ndung’u Daniel Thuo , Onyuma Samuel O.
Published: November 2022

The listed REITs have not performed as well as anticipated, and efforts by REIT management to issue further real estate securities have been delayed. This raised the question of whether the unexpected performance of REITs in Kenya was caused by external variables, including property diversification, which is out of the control of the investment market. Thus, the study sought to examine the relationship between property type-location diversification and the performance of REITs in Kenya. The target group included fund managers, stock brokers, investment banks, and property developers. A predictive correlational research design was used. At a 5% significance level, regression analysis was used to test the hypothesized relationship between variables. The results indicate that property type-location diversification has a significant relationship with the performance of REITs in Kenya. The findings also show that the location of properties is a very important aspect for REIT investors when it comes to property diversification. There was agreement among most respondents that diversifying REITs across location attributes reduces market risks. It can be concluded diversification of the REITs underlying property majorly in terms of geographic and economic influence performance of REITs in Kenya. Further, property diversification through the type of property is a key determinant in influencing the performance of REITs in Kenya. Thus, continued property-type location will enhance the uptake of REITs by investors. It is recommended that REITs issuers ensure that there is diversification of the properties to include multiple property types such as students’ hostels, retail stores, hotels, and warehouses. Such a type of diversification is likely to attract potential investors who could be interested in properties with such diversification characteristics.

Authors: Nguyen Lien To Thi , Kim Tuyen Thanh
Published: November 2022

This study aims to investigate whether the use of a text-taking strategy could enhance EFL high school learners' reading comprehension. It draws on the test-taking strategies suggested by Cohen and Upton (2007), to focus on the two main aspects, (1) the influence of applying test-taking strategies on EFL high school students’ reading comprehension tests and (2) their attitudes toward these strategies. In the pretest-posttest one-group design and descriptive quantitative research, the reading comprehension test and the questionnaire were used to collect the data of 90 EFL high school students in a school in rural Can Tho City. These students were assigned to apply test-taking strategies in a workshop every week in the second Semester of 2021-2022. The findings showed that (1) participating students’ reading comprehension scores improved after following the test-taking strategies after 07 weeks; and (2) students were positive about their being active in their testing practice despite certain challenges. As a result of such positive attitudes, they had high motivation for continuing their practice test-taking strategies for the future examination.

Authors: Dinh Dien Tri
Published: November 2022

This research was conducted to investigate the effects of technology-assisted listening practice on MOODLE on English-majored freshmen's listening proficiency as an alternative to traditional teaching and learning English. An interesting question, however, was how to apply this mode of teaching and learning English listening within the Vietnamese context. In Vietnam, few studies have been carried out on the advantages and disadvantages that university teachers and students encountered in implementing English listening practice with MOODLE assistance to meet the demands and interests of the students and support instructional practices. Therefore, this quantitative-method research was conducted to examine this interesting area with sixty-four English-majored freshmen. The data were analyzed from a pretest and post-test. The findings prove that technology-assisted listening practice on MOODLE had positive effects on English-majored freshmen's listening proficiency.

Authors: Kanari Charikleia , Souliotou Anastasia-Zoi , Papaioannou Theodora
Published: November 2022

The benefits of multisensory learning are recognized both in the field of formal education, informal and non-formal learning environments and activities. In the case of museums and museum pedagogy learning through the senses is a key element. Furthermore, the idea of a multisensory museum is steadily gaining ground within museums and among museum professionals with the ultimate aim to enrich all visitors’ museum experiences. The present paper focuses on touch in the museum. It aims to investigate primary school students’ perceptions of touch in museums as well as their experience with regard to the use of permanent display cases with touchable authentic objects during an educational program in an archaeological museum in Greece. The data were obtained via: a. evaluation questionnaires filled in by the primary school students after the visit to the museum, b. semi-structured interviews by the teachers, and c. participant observation and field notes. The results revealed how the students understand and perceive the prohibition of touch in the museum in relation to aspects of cultural heritage and exhibits’ protection. Furthermore, issues related to the appropriate approach of permanently accessible exhibition display cases and facilitations in the museum space were observed. Students’ views about their own experience confirmed the significance of touch and multisensory activities as well as the value of the combination of sensory activities, object-based learning, play and other creative and experiential methods and activities that can lead to meaningful and memorable museum experiences.

OBSERVING OR PERFORMING ACTIONS? UNDERSTANDING CIRCULAR MOTION VIA TWO TYPES OF LEARNING ACTIVITIES
Authors: Christonasis Antonios , Kotsis T. Konstantinos
Published: November 2022

Decades of research support the benefits of movement for cognitive development however this link remains unexploited in educational practice. For this reason, embodied cognition serves as the theoretical underpinnings of this study proposing that thoughts and actions are influenced by sensory experience. Fifty-eight 6th-grade students were divided into two groups: The first group participated in activities designed for full-body movement and the second observed the haptic manipulation of materials by an educator. The study thus utilized a two-group design and was conducted in phases: pretest, intervention, immediate posttest and delayed posttest. The entire process was recorded to assess students’ understanding and the multimodal text thereby created included both spoken word and bodily expressions such as posture and gestures, enabling us to closely follow the progress of every participant. The range of responses was then narrowed down to adequate and inadequate, followed by statistical processing of the data. The results showed that both execution and observation effectively contributed to the improved performance of students immediately after the interventions. Nevertheless, students who participated in bodily-based activities showed an additional advantage four months later. While this study focused solely on circular motion, the idea to investigate physical engagement and its impact on students’ understanding could be extended to other content, and the long-term effectiveness of bodily-based learning ought to encourage a redesign of the official curriculum.

The population of the study consists of 1040 teachers working in 44 primary schools in Kayapınar, Diyarbakır during the 2018-2019 academic year. Data collection tools were the "Authentic Leadership Scale", "Teacher Professionalism Scale", and “The Work Motivation Scale". Descriptive statistics, correlation, and path analysis of variables were made. SPSS 21 and AMOS 22 package programs were used in the analysis of the research. As a result of the research, it was determined that the school administrators were moderate according to the perceptions of the teachers who participated in the research on authentic leadership behaviour. In addition, the professionalism and motivation levels of teachers were found to be at good level. As a result of the correlation analysis, a positive and medium level between authentic leadership behaviors of school administrators and teacher motivation and a positive and low-level relationship was found between authentic leadership behaviors of school administrators and teacher professionalism. The relationship between teacher professionalism and teacher motivation was found to be positive and moderate. As a result of the path analysis, as the teachers' perceptions about authentic leadership behaviors of school administrators become positive, both the motivations and professional perceptions of teachers increase. In addition, it was found that teacher professionalism had a stronger predictive effect on teacher motivation than authentic leadership.

Authors: Thoidis Ioannis , Chaniotakis Nikolaos , Vrantsi Melpomeni
Published: November 2022

The purpose of this paper is to investigate the views of parents on issues of managing their children's leisure time, and in particular, to investigate the participation of parents themselves in the leisure time of their children. According to the results of the research, the organization and planning of children's leisure are based on two main principles. The first concerns the involvement of children in creative activities that offer them pleasure and the second principle concerns investing in activities that will strengthen their educational capital. Parents seek to create a supportive environment that encourages the effective use of free time in a variety of ways. As a framework for family interaction, the family's free time includes daily activities, sports interests, and also outings and excursions. Our research has shown that parents spend most of their personal free time on family responsibilities and the degree of their participation varies according to the age group and gender of the parent. However, mothers and fathers with the highest level of education, parents aged 20-40 and parents with children in lower school classes participate more in the children's free time.
