Metamizole modulates the concentrations of cytokines and hematopoietic growth factors in an experimental model of depression
(Hatay Mustafa Kemal Üniversitesi Tıp Fakültesi Dekanlığı, 2025) Maytalman, Erkan; Kıroğlu, Olcay; Berktaş, Fatih; Nemutlu Samur, Dilara; Aksu, Fazilet
In recent years, evidence of antidepressant-like activity of non-steroidal anti-inflammatory drugs has been presented. Furthermore, associations between cytokines, which are important components of the immune system, as well as hematopoietic growth factors and depression have also been demonstrated. In this study, it was aimed to analyze the effect of metamizole on the expression of cytokines and hematopoietic growth factors in mice exposed to unpredictable stress models. Method: In order to develop chronic depression behaviors, an unpredictable chronic mild stress model was applied to mice. The depression group was not given any drug and other groups were given 100 and 200 mg/kg metamizole. Forced swimming test was performed to evaluate the effect of metamizole against depression. Relative concentrations of interleukin-1 alpha (IL-1α), IL-1 beta (IL-1-ß), IL-2, IL-4, IL-6, IL-10, IL-12, IL-17, Interferon gamma (IFN-γ)-, tumor necrosis factor-alpha (TNF-α), Granulocyte-colony-stimulating factor (G-CSF), and Granulocyte-macrophage colony-stimulating factor (GM-CSF) were analyzed in serum samples of animals with semi-quantitative ELISA. Results: In the forced swimming test, the immobility time of the depression group significantly increased compared to the control group. The immobility time of groups treated with metamizole significantly decreased compared to the depression group and approached the control. Significant decreases were observed in the relative concentration levels of cytokines and hematopoietic growth factors in the groups treated with 100 and/or 200 mg/kg metamizole compared to the depression group except for IL-1α, IL-4, and IL-10. Conclusion: Evidence showing the contribution of COX enzymes to the pathophysiology of depression is increasing. In this context, the results indicate that metamizole, which can inhibit both isoforms of COX, may cause changes in cytokine levels and hematopoietic growth factors in a depression model. However, more controlled clinical studies are needed.
Data violence in networked environments: a study on user experience
(Ankara Hacı Bayram Veli Üniversitesi, 2025) Kayış, Hasan Hüseyin
In the context of networked environments, communication with other network users can introduce the element of violence into everyday life. In this case, users may encounter data violence in social media applications, which is a form of violence transferred to networked environments. In this study, data violence encountered by users in social media environments is discussed. Identifying the factors that lead to data violence is important in identifying the problem. This study aims to provide a framework for what can be done in the face of these actions that cause serious harm, along with the factors that cause data violence to occur and continue. The complaints of ordinary users about social media environments on an online complaint platform were collected through document analysis and qualitative content analysis was applied to the data. The findings showed that data violence occurs under different categories, from user to user or platform to user. Platforms' solutions to data violence are inadequate. To prevent data violence caused by the technical infrastructure of the platforms, the need for ethical design and ethical operation of the platforms was emphasized and the duties of the authorities were emphasized.
Ortaokul 7. sınıf fen bilimleri dersi kuvvet ve enerji ünitesinin kavram karikatürleri ile öğretiminin öğrencilerin kavramsal anlama seviyelerine ve akademik başarılarına etkisi
(Cumhuriyet Üniversitesi Eğitim Fakültesi, 2025) Kaymaz, Sevim; Eryılmaz Muştu, Özlem
Günümüzde hızlı artan bilgiler ile eğitim anlayışında değişiklikler yaşanmıştır. Artık öğrenciler öğretim süreçlerine aktif katılmakta, olayları sorgulamakta ve bilgileri yapılandırabilmektedirler. Fen öğretiminde kullanılan tekniklerden biri de kavram karikatürleridir. Bu çalışmada ortaokul 7. sınıf fen bilimleri dersi “Kuvvet ve Enerji” ünitesinin kavram karikatürleri ile öğretiminin öğrencilerin akademik başarıları ve kavramsal anlama seviyelerine etkisini belirlemek amaçlanmıştır. Bu araştırmanın örneklemini Konya ili Cihanbeyli ilçesindeki bir devlet ortaokulunda öğrenim görmekte olan 7. sınıf öğrencilerinden 20 kişi oluşturmaktadır. Çalışmada nicel araştırma yöntemlerinden yarı deneysel araştırma modellerinden biri olan kontrol gruplu öntest-sontest desen kullanılmıştır. Veri toplama aracı olarak “Kuvvet ve Hareket Akademik Başarı Testi” ve “Kuvvet ve Hareket Konusu Kavram Testi” kullanılmıştır. Kontrol grubuna fen bilimleri öğretim programı, deney grubunda da öğretim programı kavram karikatürleri ile desteklenerek 5 (beş) haftalık bir öğretim uygulanmıştır. Beş hafta süren öğretim bittikten sonra öğretim öncesinde uygulanan testler sontest olarak tekrar öğrencilere uygulanmıştır. Çalışmada elde edilen verilerin analizi sonrasında kontrol ve deney grubunun hem akademik başarı puanları hem de kavram testi puanları arasında istatistiksel olarak anlamlı sonuçlar bulunmuştur.
Integration of bluetooth technology and artificial neural networks in high accuracy indoor positioning
(IGI Global, 2025) Coşgun, Atıl Emre
Nowadays, with the increasing digitalization and widespread use of Internet of Things (IoT) applications, accurate and reliable indoor positioning system applications have become increasingly important. With the increasing need in the areas of use, researchers have proposed various indoor positioning system technologies and methods. In this context, Bluetooth Low Energy (BLE) technology offers a cost-effective, energy-efficient, and easy-to-integrate solution within existing infrastructures. The integration of BLE technology and ANNs for indoor positioning will be the subject of this section, which will cover the theoretical basis and practical applications. A comprehensive review of BLE-based positioning algorithms, performance evaluations, and the design and training of ANN models will be presented. In addition, the limitations of existing systems will be highlighted through the examination of the challenges. The aim of this study is to make a meaningful contribution to the field of indoor positioning and to provide applicable solutions in both academic and industrial environments.
A portfolio-focused behavioral model linking financial literacy and risk tolerance: evidence from mutual fund investors in Türkiye
(Borsa Istanbul Anonim Sirketi, 2025) Hamurcu, Çağrı; Hazar, Adalet; Babuşcu, Şenol
This study develops a portfolio-focused behavioral model to investigate how the multidimensional components of financial literacy—knowledge, attitude, and behavior—shape financial risk tolerance among mutual fund investors in Türkiye. Whereas most papers evaluate the influence of financial literacy on investment decisions using broad investor samples, this study centers on individuals who make professionally managed, portfolio-based investment decisions, thereby making a contribution to the literature. Mutual fund investors typically have higher financial awareness and structured decision-making processes, enabling a more nuanced analysis of the impact of financial literacy dimensions on risk tolerance. Drawing on behavioral finance, financial capability theory, and the theory of planned behavior, the model traces direct and indirect paths from literacy components to risk preferences. Based on data from 703 Turkish mutual fund investors and using validated Organization for Economic Cooperation and Development (OECD)/International Network on Financial Education (INFE) and Grable-Lytton scales, our structural equation model (SEM) reveals that financial behavior is the primary driver of risk tolerance, mediating the influence of knowledge and attitudes. These findings emphasize that financial literacy translates into risk-related decision-making primarily through behavior. The study highlights the behavioral dynamics of financial capability in emerging markets and calls for financial education programs that go beyond knowledge transfer to cultivate actionable attitudes and proactive behaviors among informed investors.
