Student Educational Experience and Its Place in the Modern Educational Paradigm: FEFU Case
Authors: Shcheglova Irina A. , Dremova Oksana V. , Babayeva Jennet , Gaete Magdalena Alejandra
Published: December 2024

The development of the project on creating world-class campuses in Russia heated debates on the topic of the university campus and the educational experience of students. Although it has become extremely relevant, but it remains understudied. This research is aimed at the formation of an understanding of the educational paradigm of modern Russian universities as well as the investigation of the relationship between the university space and the educational experience of students using the example of the Far Eastern Federal University (FEFU), which is a unique case among Russian universities due to its exceptional location and infrastructure. Building on the concept of Beckers and his colleagues’ theory "Purpose - Process - Place," a deductive analysis of 39 semi-structured interviews with FEFU students collected in 2022 was carried out. The study showed that higher education is undergoing a transition from a traditional behavioristic approach to social constructivism, which is manifested in the request for greater freedom in choosing not only what students should study, but when and how. The results of the study show that the educational process has moved beyond the classroom, and the educational environment has become an integral part of the educational experience of students. The results suggest that students have a need not only for learning spaces, but also for places where they can restore their resources. Thus, green spaces on the campus and an embankment with access to the water area have a favorable effect on the emotional state of students. At the same time co-workings and coffee shops can foster more productive learning. However, the location of the campus, its isolation from the mainland and its own rules of behavior and communication, forms in some students the perception of the campus as a “luxury prison” with a comfortable infrastructure but difficult to escape from. This is especially felt during the exams, when the emotional overload of students reaches peak points. The results can be useful for Russian universities participating in the project on creating world-class campuses and for researchers who study the educational environment.
Youth Is Going to Study in a Metropolis: How Not to Stay Alone
Authors: Lisovskaya Irina V. , Omelchenko Elena L. , Garifzianova Albina R.
Published: December 2024

The needs of young people who have moved to study from other cities are often overshadowed by numerous studies of international students, traditionally considered by sociologists and practitioners to be among the most vulnerable groups. In this article, we focus on the migration paths of out-of-town students in megacities and what they face on their way to discovering a new city. The aim is to reconstruct scenarios of social inclusion for nonresident students. How and in what way do young people cope with feelings of isolation and loneliness, and is it really becoming a problem for them? In conceptualizing the scenarios, we rely on the "social drama" approach. By social inclusion scenarios we understand idealized models that summarize similar narratives of student youth about the period of moving to a big city and the way to find their place in it, having their own scenario with a lead, main action and a finale. We interpret social inclusion with reference to the modern debate on citizenship, understood as a wide field of youth involvement, not limited to politicized forms. This article uses the results of a qualitative analysis of 63 interviews with students who moved to study at two universities - the Higher School of Economics in St. Petersburg and KFU in Kazan. In each case an average of 31 interviews was conducted with graduate and undergraduate students. We distinguish 6 scenarios associated by the type of plot with film genres. In each of the identified scenarios we record different types of narratives related to experiences of loneliness or isolation in the first months or even years of acquaintance with a new city.
The Reasons for Choosing a Career as an Academic Staff in Comparison to Other Employment Alternatives
Authors: Efimova Galina Z.
Published: December 2024

The article explores the main reasons why scientific and pedagogical professionals choose an academic career and university employment, given the wide range of job opportunities, limited choices, and lack of alternatives. It reveals the range of motivations for both the initial choice of a career and subsequent changes in employment, which are significant for various groups of academic professionals - those with no work experience, those who have worked outside the academic field, those who rotate within the field, and those who leave the university environment.
The empirical basis for the study is based on interviews with 145 researchers and teachers from seven leading Russian universities. The main academic motivations for choosing a career as a scientific and pedagogical professional include: the desire to share knowledge, scientific curiosity, the desire to be part of the academic community, the intellectual challenges of the academic environment, and a desire for personal and professional growth. Non-academic motivations vary depending on whether a person has access to a variety of employment options. Those who do not restrict their options to the academic sector may choose the university because of its flexible work hours, long vacation periods, social status, government support, collegial atmosphere, social security, financial stability, and deferment from military service. Scientific and educational professionals who are committed to working in academia choose the university due to the presence of a prominent research school, the prestige and standing of the academic setting, and the resources available at the university. The informants, who initially chose a particular university as their employer, noted comfortable relationships in the team as one of the motives for their decision. They also mentioned personal and family circumstances and established interaction with their supervisor as important factors in their choice. Additionally, they felt a sense of belonging to the university's dynasty, which played a role in their decision-making process.
The results of this study can be useful for university managers in their efforts to manage personnel sustainably. By understanding the motives behind the choices of their employees, managers can create a more effective system for attracting and retaining academic talent. This can help reduce staff turnover and improve the overall quality of education in Russian higher education institutions.
Modern Adaptive and Intelligent Digital Learning Systems: Mechanisms and Potential
Authors: Skvorchevsky Konstantin A. , Dyatlova Olga V.
Published: December 2024

This article examines the necessary elements of an adaptive system - the knowledge domain model, the user model, adaptivity mechanism, and explanation model - and the impact of each on the potential effectiveness of existing and potentially possible systems.
Special attention is paid to the individual characteristics that creators of adaptive systems use to build a user model. These characteristics can be grouped into 4 categories corresponding to cognitive, affective, behavioral/psychomotor, and mixed domains. The article analyzes methods for determining user characteristics and possible ways to identify them more accurately.
The article also proposes currently unused adaptivity mechanisms that focus more on mastering new tools and instruments rather than knowledge per se. In particular, it explores human-computer interaction in both individual and group formats, involving both students and teachers. In conclusion, the prospects of using artificial intelligence and collaborative tools in creating and improving adaptive systems are described, emphasizing the need for interdisciplinary collaboration and consideration of complex cognitive process models while creating and testing the systems.
A Missed Opportunity? The Transformation of the Teacher Salary System in Kazakhstan Amidst Rising Wages
Authors: Baigabylov Nurlan O. , Froumin Isak D.
Published: December 2024

This article is dedicated to analyzing the effectiveness of the reforms in the teacher salary payment system in Kazakhstan and its impact on the quality of pedagogical activity, as well as the possibility of attracting educators from universities and professionals from other sectors to schools by increasing salaries. The results are based on regional statistical data, reviews of salary dynamics, and interviews with school administrators and teachers. The article includes an analysis of previous studies of salary payment systems in Central Asian countries, characteristics of the current system in Kazakhstan, as well as the experience of transforming the Russian and Estonian teacher salary systems.
Kazakhstan, while maintaining centralized control and a "rate" system, has achieved a significant increase in the average salary of school teachers by introducing a qualifications system and a number of allowances for taught subjects and working conditions. Moreover, the increased prestige of the teaching profession, along with the rise in salaries, has facilitated the attraction of young specialists to pedagogical activities and reduced the outflow of qualified teachers from the profession. However, according to surveyed teachers, the reform has not been a significant incentive to improve teaching quality, being perceived only as a new salary increase system. This has led to the fact that, despite the undoubted success of the Government of Kazakhstan in preparing the basis for a favorable long-term perspective for supporting pedagogical workers, the measures taken at this stage lack deep understanding among teachers and do not ensure an improvement in learning outcomes.
The article aims to continue the discussion on the effectiveness of the conducted reforms, their impact on the real income increase for teachers, strengthening the status of pedagogical workers, and their motivation for professional growth.

La sinopsi del llibre de Julio Valdeón En defensa de la Historia diu textualment d'aquest que “és un apassionat al·legat en defensa d'una determinada manera d'entendre la Història i el seu ensenyament. Partint de la importància que aquesta disciplina gaudeix en la formació ideològica i política de la societat, es fa un toc d'atenció sobre el perill que suposaria un debilitament de l'ensenyament de la Història, la qual, d'altra banda, ha de ser fidel als seus senyals d'identitat.”

L'ensenyament de la geografia a l'escola
Authors: Blay Jordi
Published: December 2024

Seguint el llibre de Roser Calaf, podem veure quins han estat els antecedents i la situació actual de les relacions entre geografia i pedagogia, a més de la tendència possible i desitjable en el futur. Malgrat que en ocasions l'excés de sistematització -sens dubte, degut a la necessitat de resumir en punts concrets aspectes o idees molt més àmplies- pot tornar la lectura una mica sincopada, el cert és que és un llibre força interessant per a tots aquells que, bé sigui des de la perspectiva de la geografia o bé des de la didàctica -o des d'ambdues-, es preocupen per una major adequació de les matèries docents a les necessitats reals de l'ensenyament. I per assolir aquesta adequació cal partir d'una de les premisses bàsiques del llibre: l'ensenyament de la geografia ha d'anar adreçat, més que cap a qualsevol altre objectiu, a saber raonar l'espai, a tenir una estructuració de coneixements que permetin pensar espacialment, raonar geogràficament. Roser Calaf ens exposa les línies bàsiques que cal seguir en aquest sentit. L'administració és la que planifica els grans eixos de l'activitat docent, és cert, però al capdevall són els ensenyants els que han d'assumir i procurar assolir aquest objectiu.

Crossing Borders and Breaking Boundaries: A Comparison of the Films Happy Together (1997) and The Edge of Heaven (2007)
Authors: Liao Ruiyun
Published: December 2024

Happy Together (Wong Kar-Wai, 1997) and The Edge of Heaven (Fatih Akin, 2007) are two films that depict characters in intimate relationships that include geographical mobility. Though that is just one of the similarities they share, the two films reveal different attitudes toward life and death. The Edge of Heaven educates its audience through fear by portraying innocent people dying, while Happy Together could be interpreted more as a national allegory, given the depiction of a historical figure’s death. Nonetheless, the aim of this research is to argue that the two films are similar in that they both tell tales about revealing the experiences of moving across borders and living in cosmopolitan places. Moreover, the characters in both films expect a change in the boundaries between people and wish for a new cosmopolitan world.
What Can One See if One Brings the Linguistic Concept Into a Panchronic View?
Authors: Vakhovska Olha V.
Published: December 2024

This paper takes a panchronic perspective to show that the evolution of a linguistic concept in a worldview embraces this concept’s diachronic depth and this concept’s diachronic variation. The diachronic depth of a concept is an archaic image (modal mental representation) that was prerequisite for this concept (amodal mental representation) to emerge; this image had formed perceptually in the human mind, through the direct visual experience humans had in perceiving the world, which accounts for this concept’s embodiment. Mental image at this concept’s diachronic depth and embodiment of this concept are the two facts that this paper assumes one can see when viewing this concept panchronically. This paper treats panchrony as the combination of diachrony of language with universal processes of human cognition, and suggests that the panchronic mechanism behind linguistic semiosis is the modal-to-amodal conversion that takes place in the human mind and has the inner form of the word as its panchronic product and the image-driven interpretation of the word as its emergent product. This mechanism operates at each stage in language evolution, determines the genesis of the word as that of a sign-symbol, and is universal for the speakers of language by virtue of their embodiment. This paper’s theoretical commitments find application in the case of SIN in the English worldview: archaic image at SIN’s diachronic depth is reconstructed using methodologies of etymological research, as the inner form of the word sin in English; SIN’s content in diachronic variation is reconstructed using methodologies of cognitive linguistic research.
A Critical Sociolinguistic Study of Conservatism in Selected British Novels
Authors: Abbas Ibtihal Jasim , Shamiri Sadiq Mahdi Kadhim Al
Published: December 2024

The main point of this study is to examine the ideology of conservatism in the selected British novels The Blessing by Nancy Mitford and White Teeth by Zadie Smith through the application of a critical sociolinguistic model. These two novels were chosen for having conservatism as the main theme. In this study, conservatism was analyzed according to four phases: the first phase (initiation) shows context and conservatism types. The second phase (description) highlights the text analysis, which involves analyzing vocabulary, grammar, cohesion, and text structure. The third phase represents social analysis, which involves some social factors like age, gender, status, and style. The last phase is evaluation, in which ideology is evaluated according to some selected functions. In both novels, it seems that cultural conservatism is the most commonly used type. Further, it is shown that conservatives tend to use simple words that are easily understood by others. Additionally, declaratives, second and third person pronouns, and modality of necessity and probability are the most followed grammatical categories by conservatives. In relation to social analysis, it is proven that old people are more conservative than young ones, women are more conservative than men, uneducated people are more conservative than educated ones, and informal style is more used than formal style. With regard to evaluating conservatism, it seems that explaining, evaluating, orienting, and prescribing functions are all used in both novels.
Preserving Meaning or Form: The Dilemma of Translating Blank Verse in Hamlet Into Indonesian
Authors: Hardiyanti Diana , Santosa Riyadi , Nababan M. R. , Mugijatna
Published: December 2024

The research aims to analyze the structure of the lines of verse in "Hamlet", examines the translation techniques employed, and understands their impact. This study adopts a descriptive qualitative approach with case studies on translation products. It used purposive sampling to select documents, specifically the original verses from "Hamlet" and their Indonesian translations. It gathered insights from informants, including a literary expert, a translation expert, and raters. The research involved two types of data: linguistic data, which consists of the lines of verse in "Hamlet," and translation data, which included the translation techniques and the shifts observed in the translated text. Data collection methods included document analysis and focus group discussions, analyzed through an ethnographic model using domain, taxonomy, and component analysis to identify cultural themes. The findings show that "Hamlet's" verse contains both regular lines with five metrical foot and irregular lines that deviate from this pattern. Seventeen translation techniques are identified: paraphrase, established equivalent, transposition, modulation, reduction, variation, explicitation, compensation, implication, pure borrowing, particularization, addition, generalization, discursive creation, adaptation, literal translation, and linguistic amplification. These techniques result in translation shifts at both micro and macro levels. The study underscores the complexities of translating literary works, especially in preserving the original poetic form and meaning. Future research could compare the translation of the same literary work into various target languages, offering insights into how different translators handle similar challenges across diverse linguistic and cultural contexts and the techniques they use to achieve equivalence.
Vitality of Moi Language: A Case Study of Moi Tribes in Southwest Papua, Indonesia
Authors: Ibrahim Ibrahim , Saputra Dian , Hardianti Rinda , Lukman
Published: December 2024

This study aims to explore the language preference of Moi tribe within family settings. It ultimately seeks to evaluate how these language choices affect the preservation of the Moi language in the multilingual environment of Southwest Papua. The research involves 300 participants, categorized by gender and age. Data were gathered through semi-structured interview questionnaires and observations. The results indicate that Indonesian is primarily used in family interactions. While the participants often engage in code-switching, the findings reveal that younger generations tend to be passive speakers of the Moi language, with some lacking even a basic comprehension of their mother tongue. Factors such as social context, peer relationships, and motivation play a significant role in shaping the language choices of the participants. Furthermore, the study indicates a clear shift from the Moi language to Indonesian in the linguistic practices of the participants.

Published: December 2024

Racial injustice refers to the unfair treatment of a specific race in a community, which disadvantages one race. Therefore, this study aimed to investigate the social consequences of systemic racism and identify the various types of racial injustices experienced by Black people in the 1930s, as depicted in Wright's Native Son. Qualitative and descriptive methods, as well as Lucien Goldmann's Genetic Structuralism methods, were used. The results showed various forms of racism, including prejudice, negative stereotypes, segregation, and social isolation. These types of injustice have had a severe impact on African Americans, as seen through the protagonist, Bigger Thomas, who represented the constant state of fear, uncertainty, and frustration inflicted upon Black people. By uncovering the different kinds of racial injustice, this study emphasized the importance of societal reflection and action in eliminating long-standing racial biases and injustices.
Application of semi-quantitative loop-mediated isothermal amplification for gene expression study in Expi293 cells
Authors: Bobrovsky Pavel A. , Grafskaia Ekaterina N. , Kharlampieva Daria D. , Fisunov Gleb Yu. , Manuvera Valentin A. , Lazarev Vassili N.
Published: December 2024

BACKGROUND: Mammalian cell cultures play a key role in the pharmaceutical industry, requiring constant monitoring of the cell conditions during fermentation. In addition to monitoring of the physical-chemical parameters, it is important to evaluate the transcription state of cells, for which gene expression analysis is used. Currently, quantitative reverse transcription polymerase chain reaction (qPCR) is the dominant method. However, the loop-mediated isothermal amplification (LAMP) technique also attracts attention due to its high specificity, sensitivity and reaction rate. LAMP is becoming a promising tool for rapid analysis of gene expression, especially under the conditions of limited biological material or a large volume of samples.
AIM: Development of a technique for semi-quantifying the expression level of target genes in human cell culture Expi293 using LAMP.
MATERIALS AND METHODS: For LAMP, a recombinant large fragment of Bacillus stearothermophilus DNA polymerase (Bst-pol) was obtained, purified, and optimal reaction conditions were determined. SYBR Green I and LUCS13 were used as intercalating dyes. The amplification parameters for different concentrations of the enzyme and the dye were analyzed. Standard SYBR Green I kits were used for qPCR. Both methods were compared when analyzing the expression of IGF1, FGF2 and EIF3i genes in cell lines with an increased expression level of these genes.
RESULTS: It has been shown that using LUCS13 dye provides the classic S-shape of the signal accumulation curve in LAMP, while using SYBR Green I dye causes artifacts. The optimal concentration of Bst-pol was 40 ng/µl. When comparing the two methods, it was found that LAMP has greater sensitivity, allows determining gene expression with an accuracy comparable to qPCR, demonstrating a shorter reaction time (up to 35 minutes).
CONCLUSION: Although qPCR remains the main method for assessing the level of gene expression, LAMP offers a number of advantages that make it an attractive alternative for various biotechnological purposes. Due to its high speed, ease of execution and accessibility, as well as high sensitivity and specificity, LAMP is a valuable technique for rapid analysis of gene expression during cell culture monitoring.
A mulher guerreira na Eneida de Virgílio: Camila e Juturna
Authors: Begname Sara Meynard
Published: December 2024

RESUMO: Este trabalho pretende abordar a construção da mulher guerreira na Eneida, de Virgílio, centrando a análise em torno das figuras de Camila e Juturna. Apesar de o campo de batalha da poesia épica ser predominantemente masculino, ao longo da tradição algumas mulheres atuaram diretamente na guerra. A natureza militar dessas personagens, no entanto, contrasta com sua condição feminina e com as funções domésticas atribuídas à mulher na sociedade romana. Na épica virgiliana, nota-se como essa ambiguidade está nas bases da constituição dessas personagens, que têm pontos de contato, bem como diferenças. Ao mesmo tempo em que a atuação dessas mulheres margeia a ação masculina central, através delas importantes discursos míticos suplementares são colocados em campo.
A impossibilidade da romantização do poder: as diferenças entre Clube da Luta e Clube da Luta 2
Authors: Oliveira Diane Nascimento de , Prado Thiago Martins
Published: December 2024

Clube da Luta 2, de Chuck Palahniuk e ilustração de Cameron Stewart, dá continuidade, em quadrinhos, e comemora 20 anos da publicação do romance Clube da Luta. A narrativa da história em quadrinhos se passa dez anos após o desfecho do romance e gira em torno da vida de Sebastian e seu alterego, Tyler Durden. A partir disso, o objetivo deste trabalho é discutir a consciência de Palahniuk de que o projeto proposto e desenvolvido pelo clube, calcado nos pressupostos da zona autônoma temporária e do terrorismo poético, a longo prazo, não é frutífero. Para amparar este estudo, utiliza-se os estudos de Foucault (2006), que versa as relações de poder, e Bey (2001 e 2007), que debate sobre organizações de grupamentos autônomos, alternativos às cenas da lógica do mercado e discussão acerca de terrorismo poético. As conclusões iniciais apontam para a negação da zona autônoma temporária por Palahniuk, que demonstra a inviabilidade da romantização do poder.
Singular linear q-Hamiltonian systems
Authors: Allahverdiev Bilender , Tuna Huseyin
Published: December 2024

In this paper, a singular linear q-Hamiltonian system is considered. The Titchmarsh-Weyl theory for this problem is constructed. Firstly, we provide some necessary fundamental concepts of the q-calculus. Later, we studied Titchmarsh-Weyl functions M(λ) and circles CTW(a,λ) for this system. Circles CTW(a,λ) are proved to be nested. In the fourth part of the work, the number of square-integrable solutions of this system is studied. In the fifth part of the work, boundary conditions in the singular case are obtained. Finally, a self-adjoint operator is defined.
The Euler-like operators on tuples of Lagrangians and functions on bases

Published: December 2024

Let FMm,n denote the category of fibered manifolds with $m$-dimensional bases and n-dimensional fibres and their fibered diffeomorphisms onto open images. We describe all FMm,n-natural operators C transforming tuples (λ,g) of Lagrangians λ:JsY→⋀mT∗M (or formal Lagrangians λ:JsY→V∗JsY⊗⋀mT∗M) on FMm,n-objects Y→M and functions g:M→R into Euler maps C(λ,g):J2sY→V∗Y⊗⋀mT∗M on Y. The most important example of such C is the Euler operator E (from the variational calculus) (or the formal Euler operator E) treated as the operator in question depending only on Lagrangians (or formal Lagrangians).

When parts are machined, especially on heavy machine tools, an accurate description of the rotations around the geometric axes is required. The work adds the concept of rotation around the machine and the workpiece axes. Both types of rotation in mechanics are related to internal and external rotations, which we describe in detail. We show how both types convert to each other and how conversion formulas are derived. The resulting conversions are formalized as functions in the C and MATLAB programming languages. The result of this mathematical description will be transferred to a new transformation cycle that can be used on machines as a standard.

Determining the particle size distribution of water mist is necessary for a wide range of industrial applications or experimental measurements. Particle size defines the ability of water mist to absorb heat, absorb or scatter heat radiation, inertize the environment, reduce environmental dust, regulate odor, etc. The paper presents the principle of measuring droplet size distribution using laser diffraction and the measurement procedure for four hollow cone water mist nozzles with orifice 400 µm, 500 µm, 600 µm and 1000 µm. The measurements were performed at distances of 25 mm, 50 mm, 75 mm, 100 mm, 125 mm, 150 mm, 175 mm, 200 mm and 225 mm from the orifice of the individual nozzles in the middle of the water mist cone. Further measurements were made 25 mm, 50 mm and 75 mm from the nozzle orifices on the edge of the fog cones. All measurements were performed at a working pressure of 70 bar in a water mist system.
THE NUMERICAL SIMULATION AND EXPERIMENTAL MEASUREMENT OF A SCALED AHMED BODY MODEL WITH MODIFIED GEOMETRY
Authors:   Department of Vehicles and Engines, Faculty of Mechanical Engineering, Technical University of Liberec, ANDRLOVA KATERINA
Published: December 2024

In this work, the aerodynamic analysis of the original and modified Ahmed body was done. The principle of modification was the chamfer angle on the back sides of the Ahmed body like a boat tail, which was expected to decrease the magnitude of the drag force. The value of the aerodynamic coefficients was carried out using CFD modelling and data were validated in wind tunnel measurements. For those measurements, it was necessary to design simple aerodynamic balances, since the utilized wind tunnel was not equipped with any. It has been expected that the drag force coefficient of the modified model should be reduced compared to original geometry.

Evaluation of the economic feasibility of the same hybrid system when using a solar tracking system for photovoltaic cells. The simulation results demonstrate the hybrid system's ability to supply the required electrical energy to the loads, as well as the increase in hydrogen production when using the solar tracking system, which makes it possible to store excess hydrogen in the long term for later use when the photovoltaic energy decreases according to the seasons of the year.
Unveiling Anticancer Potential in the Interactions of Melittin Peptides with CD147 Receptor: A Structural and Functional Analysis of Ligand-Target Interactions
Authors: Denk Barış
Published: December 2024

In this study, the anticancer potential of melittin (MLT) peptides interacting with the CD147 receptor was investigated through in silico structural and functional analyses. The interaction between the transmembrane glycoprotein CD147 and cyclophilin A (CypA) activates signaling pathways crucial in cancer pathology. This study focused on the potential of melittin peptides to inhibit this interaction. Structures of the CD147 receptor and melittin peptides were obtained from the Protein Data Bank (PDB), including the three-dimensional structure of the Ig1 domain of CD147 (PDB ID: 5XF0) and melittin structures (PDB IDs: 2MLT, 6O4M, 3QRX, 8AHT, and 8AHS). Validated ligand structures were acquired through X-ray crystallography. Receptor-ligand interactions and anticancer activity were evaluated using the ClusPro2.0 molecular docking server, AnciCP2.0 and ENNAACT anticancer analysis servers, ProtScale hydrophobicity analysis, PDBSum amino acid interaction analysis, and PRODIGY thermodynamic stability analysis tools. Molecular docking simulations analyzed receptor-ligand interactions, emphasizing the role of hydrophobic interactions. Structural analysis revealed variability in peptide quality, with 2MLT demonstrating favorable attributes while 3QRX exhibited weak integrity. Anticancer analysis servers indicated that 2MLT and 3QRX, exhibiting similar binding patterns with 5XF0 and CD147/CypA, may demonstrate potential anticancer activity. Specifically, non-bonded interactions involving Gly181 and Arg201 in the 5XF0-2MLT complex and non-bonded interactions involving Pro180, Gly181, and Arg201 in the 5XF0-3QRX complex were highlighted, resembling the interaction pattern of CD147/CypA. Therefore, the importance of understanding molecular interactions and guiding drug discovery through structural examinations and computational analyses was emphasized, providing insights into the anticancer effects and drug design implications of these complexes; moreover, further research into their structural determinants and therapeutic potentials is critically essential for biomedical applications.

Background: Oocyte donation is a third-party treatment employed in assisted reproductive technology where good-quality oocytes obtained from young females are used by females with advanced age, poor ovarian reserve, and poor oocyte quality for in-vitro fertilization. A major challenge facing this treatment option is the availability of donors, and this study was done to ascertain the demographics of donors and their prior knowledge and experience of the process. The aim is to provide information that can be used to improve awareness and execution of the process.
Methods: This is a multi-center cross-sectional study that enrolled 154 participants who donated their oocytes between May 1st, 2023, and June 30th, 2024, in five major fertility clinics located in Abuja, Nigeria. Questionnaires were used to obtain data from the donors; the information obtained was analyzed using IBM SPSS Statistics 29.0.1.1. and presented as simple descriptive statistics.
Results: Average age was 23.7 years, and 71% of the participants had secondary education as their highest level of education. A total of 45% admitted to having anxieties prior to the procedure, of which 7.3% graded their anxiety as severe. During the procedure, 29.9% experienced symptoms, but only 27.1% stated that they would be willing to undergo the procedure again.
Conclusions: Opportunistic health education and adequate pre-procedure counseling are recommended to increase awareness of oocyte donation and improve the experience of the participants.

Published: December 2024

Background: This study compares the diagnostic efficacy of clinical examination and musculoskeletal (MSK) ultrasonography in detecting subacromial bursitis, highlighting their sensitivity, specificity and reliability. Subacromial bursitis is a common cause of shoulder pain.
Methods: This cross-sectional comparative study was conducted in the Department of Physical Medicine and Rehabilitation at Bangabandhu Sheikh Mujib Medical University, Dhaka, from January 1, 2024 to June 30, 2024. A total of 80 patients with suspected subacromial bursitis were evaluated, divided into two groups: clinical examination (n=40) and MSK ultrasonography (n=40).
Results: MSK ultrasonography demonstrated superior diagnostic performance with a sensitivity of 91.5% and specificity of 89%, compared to clinical examination, which showed sensitivity and specificity values of 63.2% and 57.5% respectively. The interobserver reliability measured by the Kappa Coefficient was significantly higher for MSK ultrasonography (0.88) than for clinical examination (0.50) underscoring the consistency of ultrasound imaging. MSK ultrasonography also detected specific pathological features such as bursal thickening and effusion more effectively.
Conclusions: The study emphasizes the need for improved access to MSK ultrasonography in clinical settings, especially in resource-limited areas like Bangladesh, where clinical examination is still the primary diagnostic method despite its limitations. The integration of MSK ultrasonography into routine practice could enhance diagnostic accuracy, reduce misdiagnoses and improve patient outcomes. These findings support the global trend towards imaging-based diagnostics for musculoskeletal conditions, advocating for strategic investments in diagnostic infrastructure and training to bridge the gap in healthcare delivery.

Published: December 2024

Background: Decubitus is ulcerated wounds occurring in the body regions that are exposed to prolonged pressure. Predisposition to decubitus is not fully understood. In this study, we aimed to investigate this opinion in the light of the literature.
Methods: Retrospective screening of patients in palliative care center between May 2016 and September 2017 were made with medical records of University of Health Sciences, Bursa Yuksek Ihtisas Training and Research Hospital. A total of 113 patients 43.4% (n=49) female; mean age:67.03±20.42 years hospitalized in the palliative care were included in the study.
Results: Decubitus was found in 64% (n=16) of 25 patients admitted from house, 69.6% (n=16) of 23 patients referred from the inpatient service, and 66.2% (n=43) of 65 patients referred from the intensive care unit.
Conclusions: No statistically significant difference were present between incidences of decubitus according to the status of admission. Decubitus ulcers may develop due to patient and care factors independent from time and location. This study supports this opinion by comparing the incidences between ICU, houses, and hospitals, in the light of the literature.

Background: Elective surgeries often employ either diathermy or scalpel for skin incisions, yet there is limited comprehensive research comparing the two methods. This observational study aims to compare the clinical and medical outcomes of diathermy and scalpel skin incisions in elective surgeries.
Methods: This retrospective observational study was conducted at the Enam Medical College, Dhaka, Bangladesh, over a period of 1.5 years. A total of 150 patients were included, with 75 in Group A (Scalpel Incision) and 75 in Group B (Diathermy). Various outcomes such as comorbidities, incision time, blood loss, post-operative complications, pain scores and wound grading using Surgical Site Infection (SSI) Grading were assessed.
Results: The study found that diathermy incisions were associated with shorter incision times (mean: 24.81 seconds) and reduced blood loss (mean: 1.82 ml) compared to scalpel incisions (mean incision time: 53.14 seconds, mean blood loss: 9.61 ml). Post-operative complications varied, with hematoma being more prevalent in the scalpel group (20.00%). Pain scores were consistently lower in the diathermy group across multiple post-operative days. Most participants in both groups had no SSI according to the employed SSI Grading.
Conclusions: The study suggests that diathermy may be a viable alternative to scalpel incisions in elective surgeries, offering benefits such as reduced incision time and blood loss. However, the choice between the two should be individualized based on patient characteristics and surgical requirements. Further research is needed to confirm these findings and provide more targeted recommendations.
