Article Citation - WoS: 24Citation - Scopus: 29Fungal Pathogens Associated with Crown and Root Rot of Wheat in Central, Eastern, and Southeastern Kazakhstan(Journal of Fungi, 2022) Bozoğlu, Tuğba; Derviş, Sibel; Imren, Mustafa; Amer, Mohammed; Özdemir, Fatih; Paulitz, Timoth; Morgounov, Alexey; Dababat, Abdelfattah A.; Özer, GökselKazakhstan is the fourteenth largest wheat producer in the world. Despite this fact, there has not been a comprehensive survey of wheat root and crown rot. A quantitative survey was conducted for the purpose of establishing the distribution of fungi associated with root and crown rot on wheat (Triticum spp.). During the 2019 growing season, samples were taken from the affected plants’ roots and stem bases. A total of 1221 fungal isolates were acquired from 65 sites across the central (Karagandy region), eastern (East Kazakhstan region), and southeastern (Almaty region) parts of the country and identified using morphological and molecular tools. The internal transcribed spacer (ITS), translation elongation factor 1-alpha (EF1-α), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) sequences were successfully used to identify the species of fungal isolates. It was found that Bipolaris sorokiniana (44.80%) and Fusarium acuminatum (20.39%) were the most predominant fungal species isolated, which were present in 86.15 and 66.15% of the fields surveyed, respectively, followed by F. equiseti (10.16%), Curvularia spicifera (7.62%), F. culmorum (4.75%), F. oxysporum (4.10%), F. redolens (2.38%), Rhizoctonia solani AG2-1 (1.06%), Nigrospora oryzae (0.98%), C. inaequalis (0.90%), F. pseudograminearum (0.74%), F. flocciferum (0.74%), Macrophomina phaseolina (0.66%), F. cf. incarnatum (0.33%), Fusarium sp. (0.25%), and F. torulosum (0.16%). A total of 74 isolates representing 16 species were tested via inoculation tests on the susceptible Triticum aestivum cv. Seri 82 and the results revealed that F. culmorum and F. pseudograminearum, B. sorokiniana, Fusarium sp., R. solani, F. redolens, C. spicifera, C. inaequalis, and N. oryzae were virulent, whereas others were non-pathogenic. The findings of this investigation demonstrate the presence of a diverse spectrum of pathogenic fungal species relevant to wheat crown and root rot in Kazakhstan. To the best of our knowledge, this is the first report of F. pseudograminearum, Fusarium sp., C. spicifera, and C. inaequalis as pathogens on wheat in Kazakhstan.Article The Relationship Between Mothers' Optimism and Children's Anxiety: The Mediating Role of Mothers' Psychological Resilience(Springer, 2025) Polat, PinarThis study aimed to investigate the relationships between mothers' optimism, psychological resilience, and children's anxiety, focusing on the mediating role of psychological resilience in T & uuml;rkiye. Using a cross-sectional design, data were collected from 394 mothers with children aged 4-6 through an online survey. Confirmatory factor analysis and structural equation modeling were used to analyze the data. The findings indicated a positive association between mothers' optimism and psychological resilience, and a negative association between psychological resilience and children's anxiety levels. Moreover, psychological resilience served as a mediator, indicating that mothers' optimism indirectly reduced children's anxiety by increasing psychological resilience. These findings highlight the protective role of maternal resilience in reducing children's anxiety and suggest that interventions aimed at strengthening mothers' resilience may contribute to improving children's emotional well-being.Article Citation - WoS: 44Citation - Scopus: 52Magnetic solid phase extractions of Co(II) and Hg(II) by using magnetized C-micaceus from water and food samples(ELSEVIER SCI LTD, 2019) Ozdemir, Sadin; Mohamedsaid, Siham Abdullah; Kilinc, Ersin; Soylak, MustafaA new bio-MSPE sorbent based on the use of C. micaceus and gamma-Fe2O3 magnetic nanoparticle was prepared for the preconcentrations of Co(II) and Hg(II). Critical parameters including pH, flow rate, quantity of C. micaceus, quantity of gamma-Fe2O3 magnetic nanoparticle, eluent (type, concentration and volume), sample volume, and foreign ions were examined. Surface structure and variations after interaction with Co(II) and Hg(II) of bio-MSPE sorbent were investigated by FT-IR, SEM, and EDX. The impact of bio-MSPE column reusage was also tested. The biosorption capacities were determined as 24.7 mg g(-1) and 26.2 mg g(-1), respectively for Co(II) and Hg(II). Certified reference materials were utilized to find out the accuracy of the prepared bio-MSPE method. This novel bio-MSPE method was accomplished by being applied to real food and water samples. In particular, it will be possible to make use of C. micaceus as new alternatives, in environmental biotechnology applications.Article Citation - WoS: 35Citation - Scopus: 39Highly improved solar cell efficiency of Mn-doped amine groups-functionalized magnetic Fe3O4@SiO2 nanomaterial(Wiley Online Library, 2021) Kutluay, Sinan; Horoz, Sabit; Şahin, Ömer; Ekinci, ArzuHerein, magnetic Fe3O4@SiO2 nanomaterial functionalized with amine groups (Fe3O4@SiO2@IPA) doped with manganese (Mn) was prepared, characterized and used for solar cell application. Fe3O4@SiO2@IPA-Mn was prepared via the co-precipitation and sol-gel techniques. Energy-dispersive X-ray (EDX), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) measurements were performed to examine the structure of Fe3O4, Fe3O4@SiO2, Fe3O4@SiO2@IPA and Fe3O4@SiO2@IPA-Mn. General morphology and textural properties of the prepared magnetic nanomaterials were clarified by Brunauer-Emmett-Teller (BET) and scanning electron microscopy (SEM). In addition, Ultraviolet-visible (UV-Vis) spectroscopy and thermal gravimetric analysis (TGA) were used to have a knowledge about the energy band gap and thermal behavior of the prepared magnetic nanomaterials. The energy band gap of Fe3O4@SiO2@IPA with spinel structure was determined as approximately 2.48 eV. It was understood that Fe3O4, Fe3O4@SiO2 and Fe3O4@SiO2@IPA showed type IV-H3 hysteresis cycle according to IUPAC. From the BET data, it was determined that the specific surface areas of Fe3O4, Fe3O4@SiO2 and Fe3O4@SiO2@IPA were 60.85, 28.99 and 40.41 m(2)/g, respectively. The pore size distributions of Fe3O4, Fe3O4@SiO2 and Fe3O4@SiO2@IPA were calculated as 8.55, 1.53 and 1.70 nm, respectively, by the BJH method. Also, it was observed that the dominant pore widths of Fe3O4, Fe3O4@SiO2 and Fe3O4@SiO2@IPA were calculated similar to 5.58, similar to 0.88 and similar to 17.92 nm, respectively, by the DFT method. Au/CuO/Fe3O4@SiO2@IPA-Mn/ZnO/SnO2: F solar cell device was created using existing Fe3O4@SiO2@IPA-Mn as a buffer layer. The power conversion efficiency (%) of Fe3O4@SiO2@IPA-Mn based solar cell device was calculated as 2.054. This finding suggest that Fe3O4@SiO2@IPA-Mn can be used as a promising sensitizer in solar cell technology. Moreover, in this study, the effectiveness of the modification of manganese (one of the transition metals, which is cheap and easily available) with magnetic nanomaterials in the use of solar cell technology was demonstrated for the first time.Article Citation - WoS: 25Citation - Scopus: 30Exploring the Stakeholder's Role in Sustainable Degrowth Within the Context of Tourist Destination Governance: the Case of Istanbul, Turkey(Routledge Journals, Taylor & Francis Ltd, 2020) Cakar, Kadir; Uzut, IsmailThe aim of the present study is to explore the role of tourism stakeholders in the sustainable degrowth of tourism, within the context of overtourism and destination governance. Data was gathered from document analysis and in-depth, face-to-face interviews with key tourism stakeholders in Istanbul, the most popular tourist destination in Turkey. A qualitative case study approach was adopted and content analysis was utilized as a data treatment technique. The results indicate that demarketing and applying "localhood" tourism activities are key drivers behind degrowth. Findings have also confirmed that degrowth is one solution in response to the concept of overtourism.Article Citation - WoS: 15Citation - Scopus: 17Electrocatalysis property of CuZn electrode with Pt and Ru decoration(International Journal of Hydrogen Energy, 2021) Toprak Döşlü, Serap; Döner, Ali; Yıldız, ReşitElectrocatalysis properties strongly depend on the interaction of metallic particles and this interaction enables to change the electronic structure of alloys which enhances the catalytic activity. This property is the key factor in the developing of cost-effective and efficient Hydrogen Evolution Reaction (HER) electrocatalysts for sustainable hydrogen production. In this study, novel electrocatalysts which are decorated with Pt and Ru have been developed for HER electrocatalysis. Microscopic analysis such as scanning electron microscopy (SEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD) and atomic force microscopy (AFM) are performed to determine the morphological and compositional structures. Electrocatalysis properties are evaluated by cathodic current-potential curves, electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) in 1.0 M KOH solution. Chronoamperometry (CA) and cycle tests are used for stability/durability of electrocatalysts. Results show that a small onset potential of the porous Cu/Ni/CuZn–Pt is obtained for HER. Exchange current density and polarization resistance are found to be 5.39 mA cm−2 and 2.0 Ω cm2 at overpotential of −100 mV for porous Cu/Ni/CuZn–Pt, respectively, indicating that Cu/Ni/CuZn–Pt is higher electrocatalytic properties than the others. Moreover, very low overpotentials at 10 and 40 mA cm−2 are obtained on porous Cu/Ni/CuZn–Pt compared with porous Cu/Ni/CuZn–Ru and Cu/Ni/CuZn. Porous Cu/Ni/CuZn–Pt also displays excellent stability/durability in test solution. The remarkable electrocatalysis properties of porous Cu/Ni/CuZn–Pt can be explained due to high porous structure, leaching of Zn from the deposit, intrinsic activity of Pt as well as changing in the electronic structure. It should be considered that porous Cu/Ni/CuZn–Pt is of high corrosion resistance in test solution for 120 h, which makes it good candidate for HER.Article Citation - WoS: 1Citation - Scopus: 1Determination of Bioactive and Anti-Inflammatory Molecules of Thymbra Spicata L. from Mardin by GC-MS and LC-Orbitrap HRMS: A DFT, Molecular Docking, ADMET, Biological Target and Activity Study(BMC, 2025) Unsal, Velid; Ercan, Leyla; Caliskan, Cemile GunbegiObjectives In this study, phenolic compounds (PC), volatile compounds (VC), antioxidant, anti-inflammatory, and antimicrobial properties of the Thymbra spicata L. plant grown in the Mardin Yesilli region were investigated. The properties of compounds such as rhoifolin, leucoside, naringenin, rosmarinic acid, gamma-terpinene, and carvacrol, which were found to be higher than other compounds as a result of PC and VC analysis of Thymbra spicata L. plant, and the properties of non-steroidal anti-inflammatory drugs diclofenac and ketoprofen were compared with computer-based calculations. In this context, the Absorption, Distribution, Metabolism, Excretion, and Toxicity (ADMET) profiles of the mentioned molecules were calculated, Density Functional Theory (DFT)-based quantum chemical calculations were performed, and molecular docking analyses were performed. In addition, the pharmacological properties, biological targets, and biological activities of these compounds were comprehensively evaluated. This study provides important data for understanding the therapeutic potential of these plant components. Materials and methods Chromatographic methods (GC-MS and LC-Orbitrap HRMS) were used to look at PC and VC profiles, spectrophotometry (ABTS, DPPH, CUPRAC) to look at antioxidant activities, and the disk diffusion method to look at antimicrobial properties. Results While the most detected volatile compounds were gamma-terpinene (35.34%), carvacrol (17.55%), caryophyllene (10.53%), and p-cymene (9.15%), the most detected phenolic compounds were rosmarinic acid (3334.9 ng/mL), naringenin (2610.00 ng/mL), leucoside (1956.42 ng/mL), and rhoifolin (1288.55 ng/mL). The ethanol extract of Thymbra spicata L. stopped the growth of K. aerogenes in particular. The IC50 value for DPPH was 158.01 mu g/mL, the IC50 value for ABTS was 185.03 mu g/mL, and the C0.5A value was 87.13 for the ethanol extract of Thymbra spicata L. The molecular docking results that the strongest binding energy was between TNF-alpha and naringenin (-6.77 kcal/mol), IL-6 and rosmarinic acid (-5.55 kcal/mol), and NLRP3 and carvacrol (-6.88 kcal/mol). Naringenin, rosmarinic acid, diclofenac, and ketoprofen completely violated the restrictions established by Lipinski, Ghose, Veber, Egan, and Muegge. Rosmarinic acid is the most reactive antioxidant compound with low energy deficit (Eg) and high softness (S). gamma-terpinene and carvacrol, on the other hand, are more stable and durable wit high hardness (eta) and low softness. Conclusion Naringenin, rosmarinic acid, and carvacrol demonstrate significant anti-inflammatory and immunomodulatory properties owing to their high binding affinity for TNF-alpha, IL-6, and NLRP3, positioning them as promising candidates for the treatment of inflammatory disorders. Naringenin and rosmarinic acid effectively target TNF-alpha, whereas carvacrol demonstrates potential in the management of NLRP3 inflammasome-associated diseases. The strong binding of rosmarinic acid to IL-6 shows that it can change the immune system. Thymbra spicata L., abundant in bioactive compounds, may provide benefits compared to conventional NSAIDs and exhibit potential as monotherapy or adjunctive therapies. Their strong anti-inflammatory, antioxidant, antimicrobial, and pharmacological properties, along with their safety, make naringenin, rosmarinic acid, and carvacrol good candidates for more preclinical and clinical research.Article Citation - WoS: 3Citation - Scopus: 3Muay Thai Exercises Improve Quality of Life, Love of Life and Self-Control(Frontiers Media Sa, 2025) Sahin, Oktay; Yilmaz, Coskun; Sezer, Sureyya Yonca; Sahin, Fatma Nese; Ceylan, Levent; Celikel, Baha Engin; Kirikoglu, NagihanBackground The existing research on Muay Thai sports has focused predominantly on the physiological effects of training, with limited attention devoted to the study of quality of life, love of life and self-control. The present study examined the effects of Muay Thai exercises on quality of life, love of life and self-control scores in healthy male subjects. Methods The present study comprised 50 healthy sedentary male subjects. The subjects were randomly divided into two groups: one group engaged in Muay Thai training (MTT), while the other group served as a control group (CON). The sample sizes for the MTT and CON groups were both 25. The MTT group participated in basic Muay Thai training, while the CON group continued their normal life regime. The SF-12 quality of life scale, love of life scale and multidimensional self-control scale were administered before and after the six-week training period. Results The study concluded that the six-week Muay Thai training program had a significant effect on quality of life levels, with 13.23% (p = 0.003) and 21.93% (p < 0.001) of participants demonstrating improvements in physical and mental scores, respectively. In terms of self-control levels, the program was found to have a significant effect on initiation and inhibition scores, with increases of 23.78% (p = 0.001) and 24.69% (p < 0.001), respectively. It was concluded that had a significant effect on the sub-dimensions of the Love of Life scale with increases of Positive Attitude Toward Life (PAWL) 18.63% (p < 0.001), Happy Results of the Love of Life (HRLL) 20.11% (p < 0.001) and Meaningfulness of Life (ML) 15.62% (p < 0.001), respectively. However, no significant differences were detected in any of the scales within the control group. Conclusion Muay Thai exercises had a positive effect on quality of life, love of life and self-control levels in healthy male subjects. By providing valuable insights into how Muay Thai exercise affects quality of life, love of life, and self-control, this research can guide future intervention and program design in the context of sport psychology.Article Citation - WoS: 32Citation - Scopus: 41The effect of ethnocentrism and moral sensitivity on intercultural sensitivity in nursing students, descriptive cross-sectional research study(Nurse Education Today, 2021) Yaşar, Beril Nisa; Kaya, Yunus; Arslan, Sevda; Erbaş, Atiye; Küçükkelepçe, Gürhan ErkuşBackground: Factors affecting intercultural sensitivity and care are becoming an increasingly important issue due to ethnic diversity. Nurses play a crucial role in care and therefore should keep up with this trend and improve their intercultural sensitivity. Objective and design: This descriptive cross-sectional study investigated the effects of ethnocentrism and moral sensitivity on intercultural sensitivity in nursing students. Methods and participants: Data were collected using a demographic characteristics questionnaire and the Intercultural Sensitivity Scale, Generalized Ethnocentrism Scale, and Moral Sensitivity Scale. The sample consisted of 1343 nursing students. The Pearson correlation coefficient was used to determine correlations between scale scores. Multiple linear regression was used to determine the effects of ethnocentrism, moral sensitivity, and demographic characteristics on intercultural sensitivity. Results: Intercultural sensitivity was found to be negatively correlated with ethnocentrism and positively correlated with moral sensitivity. Ethnocentrism predicted intercultural sensitivity more than moral sensitivity. Ethnocentrism and moral sensitivity explained 16.8% of the total variance of intercultural sensitivity. However, ethnocentrism affected intercultural sensitivity more than moral sensitivity did (beta = −0.406). Conclusion: Nursing education should adopt strategies to reduce ethnocentrism by helping students develop cultural competence and intercultural sensitivity. Such education can equip nurses to provide higher quality care to patients of different cultural backgrounds.Article Citation - WoS: 12Citation - Scopus: 12Protective Effect of Astaxanthin on Histopathologic Changes Induced by Bisphenol a in the Liver of Rats(Univ Agriculture, Fac veterinary Science, 2024) Karabekir, Seda Cetinkaya; Gultekin, Burcu; Ayan, Ilknur Cinar; Savas, Hasan Basri; Cuce, Gokhan; Kalkan, SerpilBisphenol A (BPA) has several potential uses, including in polycarbonate plastics and epoxy resins, which could expose humans to it. Recognized for its hepatotoxicity and ability to accumulate in organs. We prompted this study to explore the hepatoprotective potential of astaxanthin (ASTX), an antioxidant against BPA toxicity. We used 32 male Wistar Albino rats and randomly assigned them as: Control, Sham (olive oil), BPA, and BPA+ASTX. At the end of the experiment, Native Thiol, Total Thiol, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were measured in serum samples. Histopathological scoring was performed to evaluate the changes caused by ASTX in the liver. Caspase 3 and caspase 9 expression in liver tissues was demonstrated immunohistochemically and by PCR. Collagen I (COL1A1) and collagen III (COL3A1) mRNA levels were measured by PCR in the tissue samples. The BPA group showed elevated AST and ALT with decreased Thiol levels. ASTX administration reversed these changes as observed by reduced AST and ALT levels and increased Thiol levels. Histopathology indicated increased liver damage and fibrosis in the BPA group which were alleviated in the BPA+ASTX group. Gene expression analyses revealed upregulated COL1A1 and COL3A1 in BPA, which was downregulated with ASTX. Immunohistochemistry and PCR confirmed BPA-induced caspase 3 and caspase 9 expression, which were attenuated by ASTX. This study underscores ASTX's hepatoprotective efficacy against BPA-induced hepatotoxicity which ultimately attributed to its antioxidant and antiapoptotic properties. Consequently, ASTX emerges as a promising therapeutic agent for preventing and treating BPA-related liver diseases.Article The Age of Human Comparison With AI: Development of AI Competence Anxiety Scale and AI Optimism Scale and Their Relationship with Generative AI Literacy and AI Self-Efficacy(Taylor & Francis Inc, 2026) Kaya, Bilal; Gume, Sena; Ergun, NaifThe sudden penetration of artificial intelligence (AI) into daily life prompts individuals to compare their own competence with that of AI technologies. Moreover, the expectation that AI will bring many benefits keeps optimism about AI alive. Accordingly, we aimed to develop the AI Competence Anxiety Scale (AICAS) (in Studies I and II) and the AI Optimism Scale (AIOS) (in Studies III and IV) and to examine the serial mediating role of AI self-efficacy and AI optimism between generative AI (GenAI) literacy and AI competence anxiety (in Study V). Exploratory factor analysis revealed a single-factor structure for the AICAS and AIOS, and Item Response Theory found high discrimination of the items (Study I for AICAS and Study III for AIOS). Model fit values, convergent validity, composite reliability, and reliability coefficients of AICAS and AIOS were within the acceptance range (Study II for AICAS and Study IV for AIOS). As evidence of criterion-related validity, AI competence anxiety showed significant associations with AI anxiety and acceptance, whereas AI optimism was significantly related to digital well-being and AI self-efficacy. Study V found that AI self-efficacy and AI optimism mediated the relationship between GenAI literacy and AI competence anxiety. These results suggest that AICAS, for measuring AI competence anxiety, and AIOS for measuring AI optimism, are valuable and valid. They also suggest that GenAI literacy-based strategies have the potential to alleviate AI competence anxiety by enhancing AI self-efficacy and AI optimism.Article Citation - WoS: 4Citation - Scopus: 4The Role of Technology in the Future of Restaurant Labor(Emerald Group Publishing Ltd, 2025) Seyitoglu, Faruk; Atsiz, Ozan; Acar, AysegulPurposeThis research aims to explore the role of technology in the future of restaurant labor. It focused on the opinions of restaurant employees, including managers, regarding technological trends such as service robots, self-service kiosks, robot chefs and automated cooking systems and how these may affect the future of restaurant labor.Design/methodology/approachA qualitative research approach was adopted, and interviews were conducted with restaurant employees in the USA.FindingsThe findings uncovered that the benefits, impacts and shortcomings of technological trends in the restaurant industry differ depending on employees' perspectives.

We sought to report comprehensive trends in injury-related mortality and morbidity for adolescents aged 10-24 years during the past three decades. Methods Using the Global Burden of Disease, Injuries, and Risk Factors 2019 Study, we analysed mortality and disability-adjusted life-years (DALYs) attributed to transport and unintentional injuries for adolescents in 204 countries. Burden is reported in absolute numbers and age-standardised rates per 100 000 population by sex, age group (10-14, 15-19, and 20-24 years), and sociodemographic index (SDI) with 95% uncertainty intervals (UIs). We report percentage changes in deaths and DALYs between 1990 and 2019. Findings In 2019, 369 061 deaths (of which 214337 [58%] were transport related) and 31.1 million DALYs (of which 16.2 million [52%] were transport related) among adolescents aged 10-24 years were caused by transport and unintentional injuries combined. If compared with other causes, transport and unintentional injuries combined accounted for 25% of deaths and 14% of DALYs in 2019, and showed little improvement from 1990 when such injuries accounted for 26% of adolescent deaths and 17% of adolescent DALYs. Throughout adolescence, transport and unintentional injury fatality rates increased by age group. The unintentional injury burden was higher among males than females for all injury types, except for injuries related to fire, heat, and hot substances, or to adverse effects of medical treatment. From 1990 to 2019, global mortality rates declined by 34.4% (from 17.5 to 11.5 per 100 000) for transport injuries, and by 47.7% (from 15.9 to 8.3 per 100000) for unintentional injuries. However, in low-SDI nations the absolute number of deaths increased (by 80.5% to 42 774 for transport injuries and by 39.4% to 31 961 for unintentional injuries). In the high-SDI quintile in 2010-19, the rate per 100 000 of transport injury DALYs was reduced by 16.7%, from 838 in 2010 to 699 in 2019. This was a substantially slower pace of reduction compared with the 48.5% reduction between 1990 and 2010, from 1626 per 100 000 in 1990 to 838 per 100 000 in 2010. Between 2010 and 2019, the rate of unintentional injury DALYs per 100 000 also remained largely unchanged in high-SDI countries (555 in 2010 vs 554 in 2019; 0.2% reduction). The number and rate of adolescent deaths and DALYs owing to environmental heat and cold exposure increased for the high-SDI quintile during 2010-19. Interpretation As other causes of mortality are addressed, inadequate progress in reducing transport and unintentional injury mortality as a proportion of adolescent deaths becomes apparent. The relative shift in the burden of injury from high-SDI countries to low and low-middle-SDI countries necessitates focused action, including global donor, government, and industry investment in injury prevention. The persisting burden of DALYs related to transport and unintentional injuries indicates a need to prioritise innovative measures for the primary prevention of adolescent injury.

Burn wound healing, which involves various molecular and cellular mechanisms, continues to be a significant problem. Growth factors and cytokines play an active and vital role in wound healing. In the present study, the effects of kefir on wound healing in a 2nd-degree mouse burn model infected with e.coli, s.aureus and p.aeruginosa were investigated in vitro. In order to clarify the effects of kefir in the wound healing process, the macroscopic changes in kefir-applied scar tissue as well as wound depth and width were examined and IL-1α, IL-1β, IL-6, IL-8, IL-10 and TNF-α, VEGF, TGF-β protein levels were determined using the qRT-PCR method. The findings of the present study show that kefir has a positive impact on the factors playing a role in wound healing and accelerates the healing process.Article Citation - WoS: 7Citation - Scopus: 9What are the mistakes we think are correct about the Natural resource curse' hypothesis? New insights from quantile regressions via method of moments for EU(Elsevier, 2023) Savranlar, Buket; Atay Polat, Melike; Aslan, AlperThe nexus among natural resources and economic growth has recently been extensively studied in the context of the "Natural Resource Curse (NRC)" hypothesis. It is critical to use the latest analysis techniques in the development of the relevant literature. Therefore, this study aims to test the NRC hypothesis in EU member countries applying the Method of Moments Quantile Regression. Moreover, the focus of this study on EU countries for the first time fills an important gap in the literature. Renewable energy consumption, gross fixed capital formation, and urbanization are adopted as control variables. The findings demonstrate the validity of the NRC hypothesis at all quantile levels. Renewable energy consumption contributes to economic growth up to 0.70 quantile level. Additionally, gross fixed capital formation and urbanization have a positive impact on growth at all quantile levels. Empirical outputs highlight the importance of natural resources for growth in EU member countries and raise suggestions for possible policy formulation and implementation processes.Article Citation - WoS: 2Citation - Scopus: 1Body Image, Self-Esteem, and Attitudes Toward Sexuality in Older Adults With Chronic Illnesses(Springer/Plenum Publishers, 2025) Utli, Adil; Ersu, Nilay Filoglu; Ozbay, HediyeThis study aimed to examine the effect of the association between body image and self-esteem levels on attitudes toward sexuality in older adults with chronic illnesses. The research was descriptive, cross-sectional, and correlational. The study sample comprised 1,004 people over the age of 65 who visited family health centers in a province in the east of T & uuml;rkiye. The Older Person's Description Form, the Body-Cathexis Scale, the Rosenberg Self-Esteem Scale Short Form, and the Sexual Attitude Scale for Elderly People were used for data collection. For the data analysis, Pearson's r correlation test, simultaneous multiple linear regression, and binary logistic regression were employed. The mean age of the participants was 69.97 +/- 5.74 years, and 66.9% were between 65 and 74 years of age. Furthermore, 53.8% of the participants were male and 56.2% had two chronic illnesses. It was found that the participants' age, body image, and self-esteem explained 84% of the total variance in their permissive attitudes toward sexuality. Furthermore, as the age of the older adults with chronic illnesses increased, there were negative effects on their permissive attitudes toward sexuality. However, as their body image and self-esteem levels improved, there was a positive effect on their permissive attitudes toward sexuality. These findings will be of benefit in encouraging and developing sexual health in older adults with chronic illnesses.Article A New Green Corrosion Inhibitor for Mild Steel in 1 M HCl Using Erodium Cicutarium (L.) Leaf Extract: Insights From Both Theoretical and Experimental Methods(Elsevier, 2026) Ergel, Busra; Yildiz, Resit; Arslanhan, Selim; Baran, Mehmet FiratConsidering the economic and environmental conditions, corrosion appears to be a significant handicap. In this study, anti-corrosion performance of Erodium cicutarium (L.) (EC) is explored in a 1.0 M HCl using potentiaodynamic polarization (PDP), electrochemical impedance (EIS) and linear polarization resistance (LPR) spectroscopies along with morphological, structural and quantum chemical methods. FT-IR and LC-ESI-MS/MS reveal the chlorogenic acid, gentisic acid, protocatechuic acid, vanillin and salicylic acid, containing-C=O, C=C, C-H, C-H, -OH, and aromatic ring. PDP, EIS and LPR showed that at the highest concentration of the EC extract (1000 ppm), the polarization resistance and corrosion current density are measured as 974 Omega cm2 and 246 mu A cm-2, while the inhibition efficiency was found to be 98 %. Inhibition efficiencies decreased with increasing temperature and exposure times due to desorption of adsorbed inhibitor molecules from the surface. But, a notable increase in the Ea value (67.2 kJ mol-1) is observed, thereby hindering the corrosion process. While adsorption behavior is in accordance with the Langmuir isotherm, the Delta G degrees ads (-27.34 kJ mol-1) value indicates both physical and chemical adsorptions. To better understand the inhibitory mechanism, zero charge potential is determined, and quantum chemical calculations of the EC extract's components are performed.Article Citation - WoS: 32Citation - Scopus: 36Health literacy, health perception and related factors among different ethnic groups: a cross-sectional study in southeastern Turkey(BMC Health, 2021) Yiğitalp, Gülhan; Bayram Değer, Vasfiye; Çifçi, SemaBackground: Low levels of health literacy are associated with increased hospitalization rates, problems regarding the proper intake of medications, poor general health and increased mortality rates. It is a well-known fact that health literacy differs among ethnic groups and ethnic minorities, in particular, are known to have a low level of health literacy. The present study aimed to reveal the levels of health literacy among different ethnic groups and the affecting factors as well as the relationship between health literacy and health perceptions. Methods: This cross-sectional study was carried out with different ethnic groups (Kurdish, Arab, Turkish and Assyrian origin), between 18 and 65 years old in the province of Mardin in Turkey. The study was conducted with a total of 600 people. The European Health Literacy Scale-Turkish Adaptation (EHLS-TR) and Health Perception Scale (HPS) were used for measurement. Descriptive analysis, Mann Whitney U Test, Kruskal Wallis Test and Spearman correlation were used in the data analysis. Results: It was found that 80.7% of the participants had relatively low levels of health literacy. The lowest levels of health literacy were among those of Kurdish origin. There were correlations between sufficient levels of health literacy and several factors including being of Assyrian origin, being 50–65 years old, living in a nuclear family, being a secondary school graduate, having a high financial status, being retired, evaluating one’s own health status as good, obtaining health information from healthcare professionals, preferring to visit a state hospital to seek medical assistance first, smoking and drinking alcohol. A positive correlation was also identified between the levels of health literacy and health perception. Conclusions: It is essential to develop programs to increase health literacy for the public and, in particular, for the ethnic groups that are disadvantaged in many aspects in the context of health literacy.Article Citation - WoS: 8Citation - Scopus: 21Automatic Detection of Brain Tumors With the Aid of Ensemble Deep Learning Architectures and Class Activation Map Indicators by Employing Magnetic Resonance Images(Elsevier, 2024) Turk, Omer; Ozhan, Davut; Acar, Emrullah; Akinci, Tahir Cetin; Yilmaz, MusaToday, as in every life-threatening disease, early diagnosis of brain tumors plays a life-saving role. The brain tumor is formed by the transformation of brain cells from their normal structures into abnormal cell structures. These formed abnormal cells begin to form in masses in the brain regions. Nowadays, many different techniques are employed to detect these tumor masses, and the most common of these techniques is Magnetic Resonance Imaging (MRI). In this study, it is aimed to automatically detect brain tumors with the help of ensemble deep learning architectures (ResNet50, VGG19, InceptionV3 and MobileNet) and Class Activation Maps (CAMs) indicators by employing MRI images. The proposed system was implemented in three stages. In the first stage, it was determined whether there was a tumor in the MR images Tumor) were detected from MR images (Multi-class Approach). In the last stage, CAMs of each tumor group were created as an alternative tool to facilitate the work of specialists in tumor detection. The results showed that the overall accuracy of the binary approach was calculated as 100% on the ResNet50, InceptionV3 and MobileNet architectures, and 99.71% on the VGG19 architecture. Moreover, the accuracy values of 96.45% with ResNet50, 93.40% with VGG19, 85.03% with InceptionV3 and 89.34% with MobileNet architectures were obtained in the multi-class approach.Article Citation - WoS: 43Citation - Scopus: 50gamma-Fe2O3 magnetic nanoparticle functionalized with carboxylated multi walled carbon nanotube for magnetic solid phase extractions and determinations of Sudan dyes and Para Red in food samples(ELSEVIER SCI LTD, 2018) Kilinc, Ersin; Celik, Kadir Serdar; Bilgetekin, HavinHybrid nanostructures composed of gamma-Fe2O3 (maghemite) and carboxylated-multi walled carbon nanotube (cMWCNT) were used for the magnetic solid phase extractions and determination of Sudan I, II, III, IV, Para Red, Sudan Black B and Sudan Red 7B in chili products. High performance liquid chromatography (HPLC) was employed for the measurements. Limit of quantification (LOQ) values were found in the range 0.44-2.82 ng mL(-1) for analytes. The best extraction parameters were determined as pH 8.0, 40 mg of magnetic nanoparticle, 4.0 min of contact time, 0.3 mL desorption by acetonitrile. The samples were dissolved in acetone-dichloromethane-methanol (3: 2: 1, v/v/v) and diluted with acetonitrile-methanol (v/v; 80: 20) before the method was applied. Concentrations of Sudan dyes and Para Red were determined in four samples of chili powder from less than LOQ to 31.21 +/- 1.6 ng g(-1), two samples of chili tomato sauces (lower than LOQ) and two samples of ketchup (lower than LOQ).
