Analytical Investigation of Structural Behaviour of Conventional Slab and Flat Slab in Multi-storeyed RCC Framed Structure
Authors: Thakur Er. Maneesh
Published: January 2025

Analysis and design of buildings must take earthquakes into account. Analyzing how a structure will react to a given
set of loads is called structural analysis. Design is the process of determining the structure's proper parameters. It would take a
long time to do structural analysis and design by hand. Any building may be easily analysed and designed with the help of
software. The goal of this research and design study is to compare and contrast four common commercial building slab
configurations—the conventional slab, the flat slab with drop panels, the grid/waffle slab, and the structure with a load bearing
wall. At get to the results, a study was run in STAAD to analyse the impact of varying pressures on two different slab designs.
The cutting edge of computer programming. The IS-1893:2002 standard mandates the incorporation of seismic forces. We used
IS-456:2000 to determine how wide, tall, and deep to make the beams, columns, and slabs. IS-875:1987 (Parts 1 and 2) specifies
the requirements for applying load combinations, dead loads, and imposed loads (Parts 3 and 5). (Part 5). Wind speeds of 55
metres per second and an earthquake zone of 5 will be employed as criteria in the next research. The results of a research
comparing the displacements, moments, shear forces, and axial forces in two different slab pattern structures are shown using
bar charts. Data is presented in the form of tables and bar charts. In general, the greater the number of stories, the greater the
amount of movement between floors. Buildings using grid slabs performed better in the examination of the building's resistance
to wind and seismic loads, and they were also shown to be more cost-effective.

Efecto del rectificado de cuchillas sobre la calidad superficial de madera cepillada de Pino radiata
Authors: Rojas Gerson , Contreras Espinoza Sergio , Montero Claudio
Published: January 2025

La operación de rectificado permite obtener una órbita de corte única para todas las cuchillas instaladas en un cabezal rotativo. Durante este proceso, una piedra esmeril pasa sobre los filos de las cuchillas en movimiento, generando un bisel cuyo ancho varía dependiendo de la intensidad de la rectificación. Una adecuada selección del ancho de bisel es esencial para garantizar un corte homogéneo y de calidad en la superficie de la madera. Este estudio tuvo por objetivo evaluar como el ancho de bisel y el nivel de desgaste de las cuchillas (representado por la longitud de cepillado) influyen en el consumo de energía y en la calidad superficial de la madera de pino radiata. Para ello, se probaron cuatro anchos de bisel y cuatro niveles de desgaste de cuchillas, utilizando la resistencia al cizalle de uniones encoladas como indicador de la calidad de la superficie. Los resultados revelaron que tanto el ancho de bisel como la longitud de cepillado tienen una relación directa con el consumo de energía, mientras que presentan una relación inversa con la resistencia al cizalle. En función de estos hallazgos, se recomienda emplear un ancho bisel de 0,3 mm para el cepillado de madera de pino radiata, ya que presento menor consumo de energía y mayor resistencia al cizalle.
Historical Flow of Migrant Muslim Communities in Korea: A Perspective on Discontinuity
Authors: Yi Soojeong , Yang Junga
Published: January 2025

This study explores the history of Islam in Korea, focusing on discontinuity as a defining characteristic. Migrant Muslim communities, from the Koryŏ and Chosŏn periods to modern times, arrived in waves, disconnected from previous generations. This study classifies the history of Islam in Korea into four periods using primary sources, including historical texts from the Koryŏ and Chosŏn periods and records from the Japanese colonial era. It highlights the transient nature of Muslim communities in Korea, driven by shifts in international relations and the policies of ruling elites. The four periods－Shilla period (possibilities of early Muslim contact), Koryŏ and Chosŏn periods (Huihui Muslims), Japanese colonial period and Korean War (Tatar and Turkic Muslims), and post-1990 (Muslim community diversification)－illustrate how migrant Muslims have historically been brought to Korea by external forces and left with regime changes. The absence of continuity in transmitting Islamic traditions and practices between these periods reflects the complex relationship between Korea and Islam. The study concludes by addressing the challenges of integrating migrant Muslim communities into contemporary South Korean society. It proposes that a deeper understanding of this historical relationship is essential for fostering coexistence in the future.
The Violence of Looking: An Ethical Critique of Wartime ‘Comfort Women’ Photographs
Authors: Charrier Philip
Published: January 2025

This article argues for the removal of wartime ‘comfort women’ photographs and film footage from public circulation in academic, journalistic, museum, and digital contexts due to their potential to cause harm. It focuses specifically on imagery taken without consent during the Second World War, including depictions of both the living and the deceased, which risk exposing or retraumatizing victims and their descendants. While such photographs hold historical significance as evidence of the forced sexual labor system operated by the Japanese military, their continued use as illustrative or evidentiary tools risks perpetuating the structures of violence and degradation that victimized the women. Instead, carefully considered verbal descriptions, combined with survivor testimonies and contextualized historical evidence, can fulfill evidentiary and educational needs without compromising human dignity. By prioritizing survivor narratives over exploitative imagery, this approach respects the agency of those who testified while honoring the intentional silence of those who chose not to disclose their pasts.
Becoming Modern: Modernization, Psychiatry, and Mental Health in South Korea
Authors: Chi Hyunjung
Published: January 2025

This article examines how Korean psychiatrists responded to the process of modernization from the 1960s to the 1980s and its impact on the Korean population. As they shared observations about how Koreans were struggling with rapid social change, they began to shape ordinary Koreans’ understanding of mental health. Initially, psychiatry in Korea was a small marginalized medical field, with psychiatrists’ roles largely confined to academia and hospitals. In the early 1980s, psychiatrists’ previously sporadic involvement in print media intensified. Moving psychiatric expertise into the public sphere, they published self-help books and newspaper articles on various topics related to mental health written for a popular audience. Their involvement in print media illuminates how psychiatric knowledge and practice became an important part of Koreans’ everyday lives. This article aims to contribute to a deeper historical understanding of the complex interactions between psychiatry, modernization, and mental health in South Korea.

Published: January 2025

The research aimed to analyze the competitiveness and diversification of Peru’s cocoa bean exports. The main issue revolves around the need to avoid market concentration, which could lead to price dependency, and the importance of maintaining high competitiveness to ensure the continuity and leadership of exports. To this end, two key indicators were used: 1) the Herfindahl-Hirschman index (HHI), widely used in various studies, and 2) the revealed comparative advantage (RCA) indicator to evaluate competitiveness. The findings indicate that Peru maintains a competitive position in markets such as Malaysia, Indonesia, and Mexico, albeit with some variability. Additionally, it is noted that the Netherlands, Germany, Malaysia, and the United States (US) are the main importers of cocoa, with fluctuations in their import volumes. The research concludes that although Peru has achieved a comparative advantage in several markets, it is crucial to focus on improving production quality and efficiency, as well as diversifying markets to mitigate risks associated with price volatility. The relevance of the article lies in its contribution to understanding market dynamics and formulating strategies that enhance the competitiveness and diversification of Peru’s cocoa sector, ensuring its economic and social sustainability.
International diffusion of sustainable innovative automobile engine technologies: A manufacturers’ strategy
Authors: Zane Lee J. , Jaiswal Mayank , Tribbitt Mark A.
Published: January 2025

Concerns regarding the health of the planet and its economies have led to an increased focus on sustainable new technology (SNT). However, the diffusion of SNT-based products appears uneven globally. Research informs that diffusion can be influenced by multiple factors, including country policies and private sector initiatives (Albino et al., 2014). This study uses a top management team (TMT) perspective (Hambrick & Mason, 1984) to analyze auto manufacturers’ worldwide sales of electric vehicles (EVs) to understand and explain this uneven diffusion. The data indicate that individual sub-categories of EVs are developing at different rates and that significant differences exist among countries and manufacturers. These observations suggest that not all sub-categories of EVs are equal in the minds of consumers, manufacturers, and governments. Mandates from the European Union (EU) and other entities that no new internal combustion engine (ICE) vehicles can be sold after 2035 are forcing all parties in the automotive industry to work earnestly to develop EV-related technology. From a policy perspective, this research shows that government policy can work to both motivate consumers to purchase EVs and manufacturers to produce EVs. In addition, we identify avenues for future research.

Authors: Alsadoun Abdullah A. , Albaz Maged M.
Published: January 2025

The research aims to analyze the determinants of cybersecurity risk disclosure (CSRD) in Saudi Arabia and discover the influence of CSRD on both firm value and stock return volatility. The study used a mixed-methods approach that combines qualitative and quantitative techniques to determine the relationships used by the content analysis method to analyze the annual financial reports of Saudi firms for the period from 2015 to 2022, to estimate the volume of CSRD, firm value, and stock return volatility. The results of the study show that the impact of a firm’s size, age, leverage, and profitability are positive and significant on CSRD. In contrast, free cash flow has no significant effect on CSRD. Moreover, a curvilinear relationship exists between operating expenses and CSRD. In addition, Firm value is positively and significantly correlated with CSRD and many firm characteristics. However, stock return volatility is negatively and significantly correlated with CSRD in the Saudi business environment.

Authors: AlZu’bi Emad Nayef Saleem , Al-Thuneibat Ali , Mowafi Omar , Al-Hasan Melina
Published: January 2025

This paper investigates the impact of audit quality on the debt and interest coverage ratios of non-financial companies in Jordan, and the impact of the COVID-19 pandemic on this relationship. To achieve these objectives, a sample of 60 companies listed on the Amman Stock Exchange (ASE) during the years 2017–2021, was used. Descriptive statistics and multiple regression analysis were used to analyze the data and test the hypotheses. The findings of the study revealed that there is a significant negative effect of audit firm size on both the debt and interest coverage ratios, which is consistent with Mawutor et al. (2019). However, the effect of audit fees on both ratios is insignificant, which is consistent with Sayyar et al. (2015). Moreover, the impact of COVID-19 on the relationship between all variables is statistically insignificant, which contradicts the results of other studies (Kose et al., 2021). This means that the study provides additional and new evidence about the relationship between audit quality, debt ratio, and interest coverage ratio, within the context of the COVID-19 pandemic.

Diabetes Risk Following Treatment for Childhood and Young Adult Cancer Diabetes in Childhood Cancer Survivors
Authors: Cromie Kirsten , Murray Robert , Ajjan Ramzi.A. , Hughes Nicola.F. , Feltbower Richard.G. , Glaser Adam.W.
Published: January 2025

Objective: Diabetes is a potential late consequence of childhood and young-adult cancer (CYAC) treatment. Causative treatments associated with diabetes have been identified in retrospective cohort studies but have not been validated in population-based cohorts. Our aim was to define the extent of diabetes risk and explore contributory factors for its development in survivors of CYAC in the United Kingdom.

Research Design and Methods: Cancer registration data (n=4,238) was linked to electronic-healthcare databases to identify cases of diabetes through clinical coding or HbA1c. Total effect of pre-specified treatment exposures on diabetes risk was estimated using flexible parametric modelling and standardized cause-specific cumulative incidence functions (CIF).

Results: After median follow up of 14.4 years, 163 (3.8%) individuals were identified with diabetes. Total body irradiation (TBI) increases diabetes risk over time, with a 40-year CIF reaching 21.0% (95% CI: 13.8-31.9) compared to 8.4% (6.1-11.5) without TBI. Survivors treated with corticosteroids had a 7.7% increased risk at 40-years post-cancer-diagnosis. Hematopoietic stem-cell transplant (HSCT) survivors had markedly higher risk, with a 40-year CIF of 19.6% (13.4-28.6) versus 8.2% (6.0-11.3) for non-HSCT patients. Among allogeneic HSCT patients, the 40-year CIF of diabetes was 25.7% (17.4-38.0), compared to 7.9% (3.3-19.1) in autologous transplant patients.

Conclusions: This evaluation of a hospital-based cohort of CYAC identifies their increased long-term risk of developing diabetes and how this varies temporally according to treatment modalities. Notable contrasts in risk by treatment were detected as early as 10-years post cancer-diagnosis. Findings should inform the development of risk-stratified evidence-based screening.
Advancing Modal Analysis of Mechanical Linkages via Differential Algebraic Equations
Authors: Doğruer Can Ulaş , Toprak Can Barış , Yıldırım Bora
Published: January 2025

In this study, we delve into the modal analysis of mechanical linkages across arbitrary configurations. Leveraging linear elasto-dynamic modeling, we successfully decouple rigid body motion from the flexible motion associated with pseudo-dynamic equilibrium configurations. These equilibrium configurations are determined through the solution of nonlinear differential equations. Our analytical investigation reveals that the modal analysis of a mechanical linkage at arbitrary configurations is intricately tied to the position parameters of the linkage. Mode shapes and the spectrum of natural frequencies dynamically evolve as the mechanical linkage traverses space. To validate our findings, we present numerical results for a slider-crank mechanism, which are further corroborated through analytical simulations.
Collision Avoidance for Autonomous Unmanned Aerial Vehicles with Dynamic and Stationary Obstacles
Authors: Elmas Elif Ece , Alkan Mustafa
Published: January 2025

The progress of UAV autonomous navigation is steadily progressing at a much faster pace, especially in the field of real-time collision avoidance. In this study, an all-in-one solution proposed that uses a LiDAR data analysis for voxel-based environmental model creation and an optical flow (OF) for predicting moving object trajectories. By fusing LiDAR’s high-resolution spatial data with the relative motion detection capability of the OF, proposed system enables detection and avoidance of both static and dynamic objects on-the-fly. In this regard, based on a holistic perception system, the UAV can adapt to any changes in the environment, and its navigational autonomy can be enhanced. Due to these multi-tiered components, this collision avoidance algorithm is able to efficiently provide safety for UAV operations in a vast number of various conditions. Experiment and simulation results indicate that the system is capable to keep the UAV’s flight path steady through various situations where low-light or high-speed components are involved.

Published: January 2025

Background and purpose: The amount of information publicly available from arthroplasty registries is large but could be used more effectively. This project aims to improve the knowledge concerning existing registries to facilitate access, transparency, harmonization, and reporting.Methods: Within the International Society of Arthroplasty Registries (ISAR) we aimed at developing, testing, adopting, and making publicly available a short, standardized registry description with items considered relevant for stakeholders using a cross-sectional study survey. Items were chosen based on a literature review and expert advice, selected by 9 ISAR working group members, tested iteratively in 3 registries, and commented upon by 4 external experts. All 29 ISAR member registries as of July 2023 were invited to participate in the project.Results: Included items covered general descriptive information regarding registries, information related to governance, outcomes, data quality, data access, and registry production. The template was adopted, completed, and made publicly available by 25 of the 29 registries. Of those, 2/3 were national registries. 23 captured both hip and knee arthroplasties and 10 captured shoulder arthroplasties. Most registries had public reporting of data quality, methods, and results. Data was accessible in all but 2 registries, mainly as aggregated data. Important items relevant to registry quality for researchers to consistently indicate in scientific papers include scope, inclusion criteria, outcomes definitions, coverage/completeness, and validation processes.Conclusion: This ISAR initiative implemented a short, standardized description to facilitate appropriate use of orthopedic registry data worldwide relevant for a diverse group of stakeholders including researchers, industry, public health and regulatory agencies.

Published: January 2025

Background and purpose: The introduction and development of new total knee arthroplasty (TKA) implant designs are industry driven. To date, an adequately powered randomized controlled trial (RCT) to provide evidence of the superiority of novel implant designs over conventional ones is often lacking. The aim of our RCT was to investigate the functional outcomes of a novel TKA implant design compared with 2 conventional TKA designs. Primary outcome was difference in the change in Oxford Knee Score (OKS) at 2 years. Secondary outcomes were Forgotten Joint Score, 15D quality of life questionnaire, UCLA activity score, and complications.Methods: We compared functional outcomes between a novel TKA implant design (Persona CR) and 2 conventional designs (NexGen CR, PFC CR). 240 patients with severe knee osteoarthritis were recruited to a pragmatic, single-center, prospective, parallel-group RCT between September 2015 and August 2018. The duration of follow-up was 2 years.Results: Of 240 randomized patients, 225 were included in the intention-to-treat analysis (mean age 61.8 years; 67.5% females). The OKS exceeded minimal clinical important difference (MCID) from baseline to 2 years in all 3 treatment groups (Persona CR: 18.9 points, PFC CR: 20.3 points, NexGen CR: 19.4 points). At 2 years the difference between Persona CR and PFC CR in the change score was –1.0 (95% confidence interval [CI] –3.6 to 1.7). Similarly, the difference between Persona CR and NexGen CR was –0.9 (CI –3.6 to 1.9). At the time of final follow-up evaluation, OKS was equivalent between groups, as CI excluded between-group differences larger than 4 points.Conclusion: We showed no clinically relevant differences in functional outcomes measured with OKS, 15D, or FJS between the 2 conventional implant designs and the novel implant design at 2-year follow-up.

Authors: Fat Chiya Nidaul Chusna  , Taufik  , Faqihuddin Ahmad
Published: January 2025

Grieving after losing a husband is a painful experience. This study aims to explore the meaning of grieving following the loss of a husband due to COVID-19 among Muslim women in Surakarta. The study employed a qualitative phenomenological approach, with 4 Muslim women from the city of Surakarta as informants. Data was collected through in-depth interviews, and data analysis was conducted using Interpretative Phenomenological Analysis (IPA). The results of this study show that not all women interpret the death of their husbands as a purely sorrowful experience. In this study, the loss of a husband was interpreted as: (1) A decree of age from God; (2) A good death brings happiness even amidst grief; (3) The husband's death is a temporary separation. The conclusion of this study is that religiosity influences Muslim women's interpretation of the grieving process and fosters inner peace, happiness, hope, optimism, and wisdom.

Gender dysphoria refers to the experience of a significant incongruence between an individual's assigned biological sex and their identified gender. Various disciplines, including medical, psychological, and religious perspectives, provide differing explanations for this condition. This article aims to explore the issue of gender dysphoria, examining its causal factors and the Islamic perspective through a comprehensive review of existing literature. According to the literature, the causes of gender dysphoria require further in-depth investigation. Researchers suggest that dysphoric behaviour arises from a complex interplay of psychological and biological factors. Interventions for gender dysphoria may include hormonal treatments and psychological support. Additionally, individuals with gender dysphoria often face impacts and comorbidities related to body image, anxiety, and other mental health concerns. From an Islamic viewpoint, gender dysphoria is considered to contradict the natural order (fitrah) and should be addressed to restore the individual's innate disposition (fitrah).

This paper investigates the impact of access to mobile money services on household expenditure patterns in Kenya – focusing on essential expenditures: food, rent, cellphone, and transport – using data from the 2021 FinAccess household survey, which includes 22,024 households (6,134 with mobile money access and 15,890 without), we employ propensity score matching (PSM) and inverse probability weighted regression adjustment (IPWRA) to address potential selection biases. The results demonstrate that access to mobile money services increases spending on food, cellphone, rent, and transport. This indicates that mobile money can be further promoted, and relevant stakeholders or policymakers may work to increase financial literacy. However, further research is necessary to assess the impacts of expanding mobile services on household welfare, especially in disadvantaged, remote, and vulnerable communities.
THE BOY, HIS TEACHER AND THE LINGUIST: LEARNING TURKISH WITH AESOP FABLES
Authors: Safir Kassim Boudjelal
Published: January 2025

Can we “Aesopianise” other languages? This is what this article is about. You must be familiar with the fable of the Fox and the Grapes. Aren’t you? Its popularity has crossed the borders and became one of the most shared fables in the world. That popularity (1) is in fact an asset for linguists to implement the linguistic context predictability (2) using narratives. On the other hand, borrowings (3) and collocational patterns (4) can be of paramount importance to unlocking linguistically related languages. Therefore, it would be interesting to approach fables through specific strategies to try to guess familiar texts in context. To test this novel approach, we invited ten master students to participate in an experiment where they were asked to perform a series of tasks using the four linguistic tools in a game-like exercise. The results showed that participants succeeded in the post-test 26.09% of the lexicon found in ten popular fables -which is for sure not excellent but highly encouraging- when compared with that little 2.94% in the pre-test. Furthermore, the study implies that linguistic awareness preceded by cultural awareness could be a significantly powerful tool for learning any foreign language.

Improving literacy for early-grade children in primary schools in rural areas in Indonesia is a complex task due to the limited availability of reading resources and the varying teachers’ pedagogy competencies to teach students. This study aims to explore how school-based literacy programs by enhancing teachers’ teaching practices and improving the literacy learning environment at schools may improve students reading competencies, especially in lower grades. Using mixed methods, this study explains how students improve their reading competencies and this study also explores supporting factors and challenges to improve students' literacy. The sample of the study is 800 students and 92 teachers or principals in 28 primary schools in a district in West Kalimantan, Indonesia. The proportion of students who can read (categorized as a reader) improved after the program intervention. Several supporting factors that contribute to the improvement of student reading competencies have been identified such as teachers' motivation, teaching strategies, the availability of print-rich learning materials, and the support of school principals in literacy programs.

Pada abad ke-21, pembelajaran berfokus pada pemaksimalan potensi dan kebutuhan individual peserta didik dalam menghadapi tantangan global saat ini. Untuk itu, diperlukan strategi pembelajaran yang sesuai dengan tuntutan, salah satunya adalah pembelajaran berdiferensiasi. Peserta didik memiliki kecepatan belajar dan gaya belajar yang berbeda- beda, sehingga metode pengajaran yang sama tidak dapat efektif bagi semua peserta didik. Dengan pembelajaran berdiferensiasi maka memungkinkan guru untuk menyesuaikan materi, pendekatan pengajaran, dan penilaian sesuai dengan kebutuhan dan minat peserta didik, sehingga dapat meningkatkan motivasi mereka dalam belajar.Penelitian ini bertujuan untuk mengetahui peningkatan motivasi belajar peserta didik kelas VI di SDN 1 Paslakan melalui pendekatan pembelajaran diferensiasi gaya belajar. Penelitian ini menggunakan Penelitian Tindakan Kelas dengan metode kualitatif. Teknik pengumpulan data penelitian menggunakan lembar observasi motivasi belajar dan angket.. Analisis data menggunakan metode deskriptif kualitatif dari lembar observasi dan menghitung persentase hasil skala motivasi belajar. Hasil penelitian menunjukkan bahwa penerapan strategi pembelajaran berdiferensiasi berdasarkan gaya belajar berhasil meningkatkan motivasi belajar siswa. Hal ini terlihat dari peningkatan partisipasi aktif peserta didik dalam mengikuti proses pembelajaran seperti bertanya, menjawab, berdiskusi, dan menyelesaikan tugas secara tepat waktu. Pada pra-siklus, motivasi siswa rendah dengan partisipasi minim. Setelah penerapan pembelajaran berdiferensiasi pada siklus 1, terjadi peningkatan motivasi belajar meski belum signifikan. Pada siklus 2, diferensiasi proses dan konten dilakukan, hasilnya menunjukkan semua siswa aktif dan fokus dalam pembelajaran, dengan sebagian besar memiliki motivasi belajar yang baik.

Character can be defined as an individual's personality, which is shaped by a combination of positive beliefs and values, providing a foundation for perspective, thought, attitude, behavior, and action. This research employs quantitative descriptive data analysis techniques to examine the character of students at SMPN 35 Medan. The data sources for this study were students’ self-assessments and teachers' perceptions. The dimensions under investigation include honesty, responsibility, empathy, social aspects, and self-confidence. The data were collected through questionnaires, interviews, and observations involving a sample of 25 students. The results demonstrated that the dimensions of discipline and social aspects exhibited the highest levels of development, with a value of 64%. This was followed by the dimensions of responsibility and empathy, which demonstrated a percentage of 60%. Finally, the dimension of self-confidence exhibited the lowest level of development, with a percentage of 28%. This study recommends the crucial role of teachers in shaping students' character through literacy programs, interactive methods, and educational sanctions.

Field trips are not merely an escape from the classroom; they are powerful tools to bridge theoretical concepts with real-world experiences. The fire disaster mitigation program for early learners at a local fire station introduced children to essential fire safety practices while reshaping their understanding of heroism and inspiring new aspirations. This study aimed to evaluate the program's implementation, its impact on children’s understanding of fire safety, and the development of critical thinking and career aspirations. Using a qualitative approach, data were collected through direct observation, interviews with students, teachers, and parents, and an analysis of program materials. Thematic analysis revealed that children gained a deeper appreciation for real-world heroism, comparing firefighters to figures like Captain America and Iron Man, while also reflecting critically on fire safety concepts, such as the importance of safe assembly points in their daily environments. Additionally, the program sparked new career aspirations among the children, particularly among boys, although gender stereotypes persisted with fewer girls expressing interest in firefighting. Despite its strengths, such as engaging presentations and hands-on simulations, the program exhibited limitations, including minimal parental involvement and a lack of diverse role models. These findings suggest that targeted improvements, such as incorporating follow-up activities, enhancing parental engagement, and introducing gender-inclusive narratives, could significantly enhance the program’s impact.
Kóros tirozinizomerek hatása a krónikus inzulinrezisztencia kialakulására és az M1/M2 polarizáció irányára makrofágokban

Elhízás esetén a fehér zsírszövet gyulladásos citokineket expresszál, ami inzulinrezisztenciához vezet. A fenilalaninból szabad gyökök által termelt, nem fiziológiás meta-tirozin és orto-tirozin (meta-Tyr és orto-Tyr) hozzájárulhat az inzulinrezisztencia kialakulásához. Az ebből eredő inzulinrezisztencia jelentős hatással lehet a makrofágok működésére. Ebben a tanulmányban a meta- és orto-Tyr hatását vizsgáltuk a makrofágok inzulinérzékenységére és M1/M2 polarizációjára Akt-foszforiláció és argináz-1/iNOS arány segítségével. A makrofág-sejtvonalakat para‑, meta- vagy orto-Tyr, 5 mmol/l vagy 25 mmol/l glükózt tartalmazó médiumban tenyésztettük (para25-Tyr csoport), és inzulinnal kezeltük. A para25, a meta- és orto-Tyr növelte a pAkt-szintet és csökkentette az argináz-1/iNOS arányt a makrofágokban inzulin hiányában. Fiziológiás para-tirozin-kezelés esetén az inzulin növelte a pAkt mennyiségét és csökkentette az argináz-1/iNOS arányt. Mind a meta‑, mind az orto-Tyr-kezelés képes volt megszüntetni vagy megfordítani az inzulin pAkt-ra gyakorolt növelő hatását és az argináz-1/iNOS arányra gyakorolt csökkentő hatását. Eredményeink arra utalnak, hogy a nem fiziológiás tirozinizomerek befolyásolhatják a makrofágok inzulin-jelátvitelét és M1/M2 polarizációját.
