Article Comprehensive Proteomic and Metabolomic Analysis of Novel Substituted Fluoroquinolone Derivatives in Escherichia Coli Isolates(John Wiley and Sons Ltd, 2026) Nigiz Ş.; Kulabaş N.; Türe A.; Kablan S.; Koçak E.; Özkul C.; Küçükgüzel İ.; Koçak, Engin; Nigiz, Şeyma; Kablan, Sevilay Erdoğan; Özkul, Ceren; Kulabaş, Necla; Küçükgüzel, İlkay; Türe, AslıAntimicrobial resistance is one of the most important global problems, and new antibiotic requirements have been emerging as a key point in this issue. In the present work, we focused on the efficiency of two novel promising fluoroquinolone derivatives on resistant Escherichia coli isolates at the molecular level. Their mode of action and adaptation process were evaluated by using proteomics and metabolomics analysis. Proteomics analysis showed that two compounds have an effect mainly on the ribosomal process and energy metabolism. Moreover, we observed compounds that affect various important antimicrobial targets, such as ribosomal subunits, phosphotransacetylase, and chaperone proteins. In metabolomics analysis, we found that compounds altered bacterial metabolism directly. Pathway analysis showed that cofactor biosynthesis and energy metabolism were affected mainly by undertreated groups. Our experiments demonstrated that novel fluoroquinolone derivatives have promising results at the molecular level and results will contribute to further studies. © 2026 John Wiley & Sons Ltd.Article Telerehabilitation Transforms Recovery: Elevating Outcomes for Lower Limb Amputees(Wolters Kluwer Health, 2026) Ozturk, BasarBackground: Telerehabilitation provides a viable alternative for individuals facing barriers to in-person rehabilitation because of transportation issues and physical limitations. It enables remote monitoring and guidance, allowing patients to continue rehabilitation at home. Objective: This study aimed to assess the effectiveness of a telerehabilitation program in improving physical and psychological outcomes for lower limb amputees and to evaluate adherence to a home-based exercise program delivered via video. Study design: A randomized controlled trial. Methods: Sixty participants with lower limb amputations were randomized to an experimental group (telerehabilitation) or a control group (standard care). The intervention involved a 4-week supervised phase followed by a 4-week unsupervised phase. Primary outcomes were physical capacity, measured by the Six-Minute Walk Test (6MWT), and psychological status, assessed using the Hospital Anxiety and Depression Scale. Secondary outcomes included adherence rates and patient satisfaction. Results: The experimental group showed significant improvements in 6MWT distance and Hospital Anxiety and Depression Scale scores compared to the control group. The mean 6MWT distance increased by 20% from baseline to the end of the supervised phase (P < 0.01) and was maintained during the unsupervised phase. Anxiety and depression scores significantly decreased (P < 0.05). Adherence was higher during the supervised phase (85%) but dropped during the unsupervised phase (60%). Conclusions: Telerehabilitation significantly improved physical and psychological outcomes for lower limb amputees. High adherence during the supervised phase emphasizes the importance of clinician support, whereas strategies are needed to sustain long-term engagement during the unsupervised phase.Article 1,2,4-Triazole Conjugates as HEGFR Inhibitors: Synthesis, Anticancer Evaluation, and in Silico Studies(Wiley-V C H Verlag GmbH, 2026) Bulbul, Bahadir; Kulabas, Necla; Gurboga, Merve; Ozakpinar, Ozlem Bingol; Cakmak, Ummuhan; Tuncay, Fulya Oz; Kucukguzel, IlkayA series of novel 1,2,4-triazole-acetamide derivatives was synthesized and evaluated for anticancer and hEGFR inhibitory activity. The compounds were obtained via multistep synthesis and characterized by spectroscopic methods. Cytotoxicity was tested against PC-3, MCF-7, A549, and K562 cell lines. Compounds <bold>18</bold>, <bold>19</bold>, and especially <bold>24</bold> showed notable antiproliferative effects, with compound <bold>24</bold> exhibiting higher selectivity and potency than gefitinib. It also induced apoptosis and inhibited migration in A549 and PC-3 cells, while selectively promoting invasion in PC-3, suggesting EMT-related behavior. In vitro kinase assays revealed compound <bold>20</bold> as the most potent hEGFR inhibitor (IC50 = 43.8 +/- 1.3 nM). Molecular docking and 200 ns molecular dynamics simulations confirmed its stable interaction with EGFR, particularly involving Cys797. These findings highlight compounds <bold>20</bold> and <bold>24</bold> as promising candidates for further development as EGFR-targeted anticancer agents.Article In Vivo Antioxidant and Anti-Inflammatory Effects of Myrtus Communis Against Ionizing Radiation-Induced Gastrointestinal Injury: Trod-Grog Study(Kare Publishing, 2025) Kilic, Melisa Bagci; Varan, Melike Pekyurek; Atasoy, Ozum; Ozyilmaz, Nagehan; Pazarbasi, Seren Ede; Ertas, Busra; Atasoy, Beste Melek; Ercan, FerihaOBJECTIVE: This study aimed to investigate the in vivo radioprotective effects of Myrtus communis (MC) on the gastrointestinal system. METHODS: A total of 30 female rats were divided into four groups: i) Control; ii) irradiation (IR) only; iii) MC-pretreated; and iv) MC-treated. The rats received oral MC extract (100 mg/kg/day) for 4 days before exposure to 10 Gy IR or continued until sacrifice. On the fourth day of IR exposure, the rats were sacrificed, and histopathological and biochemical analyses were performed on the ileum, pancreas, and liver tissues. RESULTS: Malondialdehyde and myeloperoxidase levels decreased in both MC-treated groups, while glutathione levels and Na+-K+-ATPase activity increased (p<0.01), with significant histopathological improvements compared to the IR-only group. CONCLUSION: The results of this study demonstrate that MC significantly decreases ionizing radiation-induced oxidative and inflammatory damage in the gastrointestinal systems of rats. Therefore, it may be regarded as a new candidate with radioprotective potential for future clinical application.Article The Relationship Between Spiritual Well-Being, Resilience, and Adherence Among Patients Receiving Hemodialysis Treatment in Türkiye(Springer, 2026) Bulbul, Elif; Sukut, Ozge; Dikec, GulThis study examined the relationship between spiritual well-being, resilience, and adherence of hemodialysis patients and the factors affecting them. The data were collected from 182 hemodialysis patients receiving treatment in a dialysis center who met the inclusion criteria by purposive sampling method in Istanbul. The data were collected with the patient description questionnaire, which measures patient sociodemographic characteristics and characteristics related to the medical diagnosis, the Spiritual Well-Being Scale, the Brief Resilience Scale, and the End-Stage Renal Failure-Adherence Questionnaire. Gender, educational status, employment status, and mean age of patients were found to be correlated with psychological resilience. Marital status, employment status, cohabitants, and mean age of patients were found to be correlated with spiritual well-being. Gender, number of weekly dialysis sessions, and dialysis competencies were found to be correlated with hemodialysis patients' adherence to their treatment. Hemodialysis patients' adherence was positively correlated with both the faith subscale of spiritual well-being and psychological resilience. According to regression analysis, gender and resilience explained 12.8% of the total variance of adherence. This study determined that resilience is an essential factor in increasing the adherence of hemodialysis patients.Article Evaluation of Barriers to the Integration of Renewable Energy Technologies into Industries in Türkiye(MDPI, 2026) Caloglu Buyukselcuk, Elif; Turan, HakanThe transition to renewable energy technologies is one of the most important ways to achieve the sustainable development goals (SDGs) of affordable and clean energy (SDG7); industry, innovation and infrastructure (SDG9); responsible production and consumption (SDG12); and climate action (SDG13). The widespread use of renewable energy technologies in developing countries will reduce dependence on imported fossil resources, increase industrial competitiveness, and support low-carbon development. Despite all their advantages, the integration of renewable energy technologies into industrial and domestic systems in developing countries remains slow due to a number of barriers. Financial constraints, technical and technological deficiencies, political restrictions and uncertainties, and organizational and managerial inadequacies are some of the barriers to the widespread adoption of renewable energy technologies. This study aims to identify, classify, and prioritize the barriers to the implementation of renewable energy technologies by applying multi-criteria decision-making methods in a fuzzy environment, with T & uuml;rkiye considered as a case study. The relative importance of the barriers identified using the Single-Valued Spherical Fuzzy SWARA method was assessed, and their interconnections and significance were systematically demonstrated. The findings will contribute to the development of policy and management strategies aligned with global sustainability goals, thereby facilitating a more effective and equitable transition to clean and resilient energy systems.Article Advances and Strategies in Biosensor-Based Diagnostics for Parasitic Infections: A Comprehensive Scoping Review(Springer, 2026) Aminizadeh, Selva; Alizadeh, Gita; Alizadeh, Zahra; Khalilzadeh, Balal; Abidin, Zurina Zainal; Marzi, Mahdi; Rafiei-Sefiddashti, RahelehParasitic diseases are among the most widespread infections worldwide, causing millions of deaths and illnesses each year. So rapid and accurate diagnosis is essential, requiring highly sensitive and specific tests. Biosensors can provide significant advantages over traditional diagnostic methods because of their specificity, sensitivity, speed, simplicity, ease of use, repeatability, and capacity for early-stage disease detection. Recent advances in modern diagnostic tools for detecting parasitic infections use nanomaterials such as gold nanoparticles, carbon nanofibers, and carbon nanotubes. These developments have significantly lowered detection limits to the picogram and femtogram levels. This review will cover recent advancements in biosensor-based diagnostic techniques in parasitology.Article Montelukast Attenuates Abdominal Aortic Aneurysm in Rats: Anti-Inflammatory and Antioxidant Effects(Elsevier, 2026) Tekin, Gozde; Cevik, Ozge; Cetinel, Sule; Sener, Goksel; Kizilay, MehmetObjective: Oxidative stress and inflammation are widely recognized as central mechanisms in the pathogenesis of abdominal aortic aneurysm. This study sought to examine the potential protective properties of montelukast in a rat model of aortic aneurysm. Methods: Male Sprague-Dawley rats were randomly allocated into three experimental groups. Abdominal aortic aneurysm was induced using the calcium chloride (CaCl2) model, in which gauze soaked in 0.5 M CaCl2 was placed directly onto the adventitial surface of the infrarenal abdominal aorta for 15 minutes. After induction, the treatment group received daily intraperitoneal injections of montelukast (10 mg/kg) for 4 consecutive weeks. At the study end point, animals were euthanized, and infrarenal aortic tissues were harvested for biochemical and histological evaluations. Measured parameters included matrix metalloproteinase (MMP)-2 and MMP-9 expression, myeloperoxidase (MPO) activity, and 8-hydroxy-2 '-deoxyguanosine levels. Antioxidant capacity was assessed through superoxide dismutase (SOD) activity assays. Histopathological examinations were performed, and statistical analysis was conducted using GraphPad Prism v.5. Results: Exposure to CaCl2 triggered pronounced oxidative injury and inflammation, as evidenced by elevated 8-hydroxy-2 '-deoxyguanosine levels, increased MPO activity, reduced SOD activity, and upregulated MMP-2 and MMP-9 expression. Montelukast administration markedly attenuated these changes, normalizing oxidative and inflammatory markers while improving histopathological architecture. Conclusions: Montelukast effectively counteracted CaCl2-induced aortic damage. The protective effects of montelukast appear to be mediated through suppression of MMP activity, restoration of SOD levels, and reduction of MPO-driven oxidative injury. By mitigating both inflammatory and oxidative mechanisms, montelukast contributes to the preservation of aortic wall structure. Clinical Relevance: Abdominal aortic aneurysm remains a major vascular disorder without an effective pharmacological therapy to slow its progression. In this experimental study, montelukast, a leukotriene receptor antagonist widely used in asthma, attenuated abdominal aortic aneurysm formation in rats and was associated with increased superoxide dismutase activity, reduced myeloperoxidase levels, and suppressed matrix metalloproteinase activation. These combined antioxidant, anti-inflammatory, and matrix-stabilizing effects preserved aortic wall integrity. Given montelukast's established safety and clinical availability, these findings support its potential for future clinical investigation as a pharmacological approach to limit aneurysm progression.

Sixty individuals aged 18-50 years with CLBP due to LDH were randomized into two groups: peloid therapy (n=30) and hot pack therapy (n=30). Treatments were applied five days a week for 15 sessions, and all partici-pants received 20 minutes of lumbar TENS per session. Evaluations were conducted before and after treatment, including pain (VAS), Back Pain Functional Scale (BPFS), Oswestry Disability Index (ODI), quality of life (SF-36), range of motion, and finger-floor distance (FFD). Peloid group showed significant improvements in BPFS, physical functioning, role limitations due to emotional problems, vitality, emotional well-being, pain, and general health compared to the hot pack group (p<0.05). Both groups showed significant reducti-ons in VAS, ODI and FFD scores (p<0.05), with no significant between-group differences (p>0.05). In conclusion, while both treatments were effective in reducing pain and disabili-ty, peloid therapy provided superior improvements in functional status and quality of life compared to hot pack therapy.Article Assessment of Artificial Lighting Conditions in Sunlight-Deprived Classrooms(Gazi Univ, Fac Engineering Architecture, 2025) Duyan, Fazila; Kaplan, ElifNumerous studies on classroom lighting emphasize a close and significant relationship between students' concentration, comprehension of course content, and the efficiency of activities such as drawing, writing, and practices, with the lighting conditions. In this context, it is particularly important to properly design both the physical and psychological effects of artificial lighting, especially in sunlight-deprived classrooms. This study examines the artificial lighting conditions of a classroom located in the basement of a university building, which has no visual connection to the outdoors. The classroom is utilized by students from the departments of Architecture, Interior Architecture, and Industrial Design. The study investigates the effects of current artificial lighting on students, focusing on aspects such as visual perception satisfaction, light colour, illuminance level, glare, and the temporal light modulation effect. To assess students' perception of the existing lighting conditions, an online questionnaire was administered, and a total of 104 students (65 female, 39 male) who had previous experience with the classroom participated in the study. Technical measurements of the existing luminaires were conducted, and the classroom was digitally modelled using the DIALux Evo lighting software. The collected data were analysed using the SPSS statistical analysis program. The findings of the study indicate that students perceived the artificial lighting conditions as inadequate in terms of visual comfort. Moreover, based on technical measurements, simulations, and user evaluations, it was determined that the existing luminaires caused glare and temporal light modulation effects, negatively affecting the classroom environment.
