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: 7Citation - Scopus: 6Protective effects of dexmedetomidine on ischaemia-reperfusion injury in an experimental rat model of priapism(Andrologia, 2021) Unsal, Velid; Kölükçü, Engin; S. Parlaktaş, Bekir; Kölükçü, Vildan; Fırat, Fatih; Deresoy, Faik A.; Katar, Muzaffer; Kuyucu, Yunus EmreThe study aimed to investigate the effects of dexmedetomidine against ischaemia-reperfusion injury occurring after priapism in a model of induced-priapism in rats. A total of 18 male rats were randomised into three groups. Group 1 was the control group. A priapism model was performed rats in Group 2 and then ischaemia-reperfusion injury was evaluated. Group 3 had similar procedures to the rats in Group 2. Rats in Group 3 additionally had 100 μg/kg dexmedetomidine administered intraperitoneally immediately after reperfusion. Blood and tissue samples were analysed. Biochemical analysis of blood samples revealed a decrease in the levels of the pro-inflammatory cytokines including interleukin-1 beta (IL-1 Beta), interleukin-6 (IL-6), and tumour necrosis factor-alpha (TNF-alpha) in Group 3 compared to Group 2 (p:.04, p:.009 and p:.009, respectively). Similarly, the highest malondialdehyde (MDA) level was in Group 2 (p:.002). The levels of antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities were significantly higher in Group 3 than that of Group 2 (p:.037 and p:.045, respectively). Direct microscopic examinations revealed positive changes in desquamation, oedema, inflammation and vasocongestion scores in Group 3 compared to Group 2 (p:.007, p:.008, p:.007 and p:.006, respectively). Dexmedetomidine has a protective effect against ischaemia-reperfusion injury in penile tissue.Article Citation - WoS: 7Citation - Scopus: 9The younger Dryas layer at Boncuklu Tarla and the beginning of village life in the upper Tigris Basin(ScienceDirect, 2023) Kodaş, ErgülRecent archaeological excavations in the Boncuklu Tarla, Çemka Hoyük, ¨ and Kortik ¨ Tepe settlements in the Upper Tigris Basin have provided a number of finds from the pre-PPNA Period, the Younger Dryas. The new data also opens up the concept of the Proto-Neolithic Period to discussion again, which has been controversial for a long time in the East Jazeera and Northwest Zagros Region. In this context, architectural remains and other small finds discovered in the Boncuklu Tarla settlement area make it possible to re-examine the transition to sedentary life in the Upper Tigris Basin during the Late Epipalaeolithic/Proto-Neolithic Period and the PPNA Period. These archaeological finds show that there were some semi-sedentary or sedentary communities in the Upper Tigris Basin, which exhibits unique geographical and climatic features, starting with the Younger Dryas Period. This is different from the Natufian culture that is thought to have emerged in the Mediterranean temperate climate zone and is known only in the Southern Levant Region.Article Citation - WoS: 34Citation - Scopus: 38Fabrication and characterization of 3,4-diaminobenzophenone-functionalized magnetic nanoadsorbent with enhanced VOC adsorption and desorption capacity(Environmental Science and Pollution Research, 2021) Ece, Mehmet Şakir; Şahin, Ömer; Kutluay, Sinan; Horoz, SabitThe present study, for the first time, utilized 3,4-diaminobenzophenone (DABP)-functionalized Fe3O4/AC@SiO2 (Fe3O4/AC@SiO2@DABP) magnetic nanoparticles (MNPs) synthesized as a nanoadsorbent for enhancing adsorption and desorption capacity of gaseous benzene and toluene as volatile organic compounds (VOCs). The Fe3O4/AC@SiO2@DABP MNPs used in adsorption and desorption of benzene and toluene were synthesized by the co-precipitation and sol-gel methods. The synthesized MNPs were characterized by SEM, FTIR, TGA/DTA, and BET surface area analysis. Moreover, the optimization of the process parameters, namely contact time, initial VOC concentration, and temperature, was performed by applying response surface methodology (RSM). Adsorption results demonstrated that the Fe3O4/AC@SiO2@DABP MNPs had excellent adsorption capacity. The maximum adsorption capacities for benzene and toluene were found as 530.99 and 666.00 mg/g, respectively, under optimum process parameters (contact time 55.47 min, initial benzene concentration 17.57 ppm, and temperature 29.09 °C; and contact time 57.54 min, initial toluene concentration 17.83 ppm, and temperature 27.93 °C for benzene and toluene, respectively). In addition to the distinctive adsorptive behavior, the Fe3O4/AC@SiO2@DABP MNPs exhibited a high reproducibility adsorption and desorption capacity. After the fifth adsorption and desorption cycles, the Fe3O4/AC@SiO2@DABP MNPs retained 94.4% and 95.4% of its initial adsorption capacity for benzene and toluene, respectively. Kinetic and isotherm findings suggested that the adsorption mechanisms of benzene and toluene on the Fe3O4/AC@SiO2@DABP MNPs were physical processes. The results indicated that the successfully synthesized Fe3O4/AC@SiO2@DABP MNPs can be applied as an attractive, highly effective, reusable, and cost-effective adsorbent for the adsorption of VOC pollutants.

The results indicated that Hg(II) was more toxic than Pb(II) to E. profundum. E. profundum was also more tolerant in solid medium than in liquid medium for Pb(II) and Hg(II). The bacterial growth was not significantly influenced at 1.0 and 2.5 mg/L Pb(II) and Hg(II) for 24 h. The highest Hg(II) and Pb(II) bioaccumulation amounts were determined as 37.56 and 54.35 mg metal/dried bacteria, respectively. Bioaccumulation capacities of the cell membrane of E. profundum forHg(II) and Pb(II)were determined. The different concentrations of Pb(II) and Hg(II) enhanced the SOD and CAT enzymes. In addition, variations of the surface macrostructure and the functionality of E. profundum after the interaction with Hg(II) and Pb(II) were investigated by the scanning electron microscope (SEM) and the Fourier transform infrared spectroscopy (FT-IR), respectively. This investigation obviously showed that thermophilic E. profundum can also be applied for removal and recovery of toxic metals from industrial wastewater. Clearly, a further investigation should be utilized by thermophilic microorganisms. According to antioxidant enyzme activities, E. profundum can be also used as a bioindicator for the detection of toxic metal pollution in natural water samples. © 2019, © 2019 Taylor & Francis Group, LLC.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.Other Citation - WoS: 6Lise öğrencilerinin matematik okuryazarlığına yönelik öz-yeterlik inançlarının belirlenmesi(2011) Özgen, Kemal; Bindak, RecepBu araştırma, lise öğrencilerinin |9., 10., U. ve 12. sınıf! matematik okuryazarlığı öz yeterlik inançlarını belirlemeyi ve öğrencilerin öz yeterlik inançlarının cinsiyet, sınıf, okul türü, matematik dersi basan puanı, anne-baba eğitim durumu ve matematik dersine verilen önem değişkenlerine göre incelemeyi amaçlamaktadır.

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.

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.

It affects individuals of all ages, races, and backgrounds. Since drugs used to treat cancer cannot distinguish between cancerous and healthy cells, they cause systemic toxicity along with serious side effects. Recently, controlled drug-release systems have been developed to reduce the side effects caused by anticancer drugs used for treatment. Morin is an anticancer drug with a flavonol structure. It has been extensively researched for its antioxidant, anti-inflammatory, antitumoral, and antibacterial properties, especially found in Chinese herbs and fruits, and its multiple positive effects on different diseases. In this study, a nanocomposite with magnetic properties was synthesized by coating biocompatible activated carbon obtained using the fruits of the Celtis tournefortii plant on the surface of iron oxide magnetic nanoparticles. Characterization of the synthesized activated carbon-coated iron oxide magnetic nanocomposite was confirmed by Fourier transform infrared, scanning electron microscopy, energy-dispersive X-ray spectrometry, X-ray diffraction, dynamic light scattering, zeta potential, and vibrating sample magnetometry. The cytotoxic effects of the drug-loaded magnetic nanocomposite were examined in HT-29 (colorectal), T98-G (glioblastoma) cancer cell lines, and human umbilical vein endothelial cell (HUVEC) healthy cell line. The morin loading and release behavior of the activated carbon-coated iron oxide magnetic nanocomposite were studied, and the results showed that up to 60% of the adsorbed morin was released within 4 h. In summary, activated carbon-coated iron oxide magnetic nanocomposite carriers have shown promising results for the delivery of the morin drug.Article Citation - WoS: 1Citation - Scopus: 1Spectroscopic and microscopic analysis of yarn sample found in Başur Höyük Early Bronze Age Cemetery(Elsevier, 2023) Sağlamtimur, Haluk; Gündüz Balpetek, Fatma; Süpüren Mengüç, Gamze; Batıhan, Metin; Aydoğan, İnan; Özmen Batıhan, Öznur; Boz, Serkan; Demsar, AndrejThe Early Bronze Age cemetery at Başur Höyük (Siirt, Türkiye), dated back to the 3rd millennium BC, contains a wide range of ancient artifacts. Thousands of finds consisting of various metal objects, pottery, stone and textile artifacts were excavated from the site, where a total of 18 graves were found and excavated. The well-preserved textile artifacts, found especially on metal objects, are the subject of the present article. The article presents the initial results of the joint work of the archaeologists and textile engineers involved in the archaeological excavation project at Başur Höyük. The paper presents general information about the uses of the textile materials found in the Başur Höyük EBA burial site and the Başur Höyük graves, concluded on the basis of their relationship with the other excavated materials. In addition, the results of the quantitative analyses of the yarn artifact is presented, which were carried out using non-destructive analytical methods, such as: FTIR spectroscopy, scanning electron microscopy (SEM) and SEM microscopy with energy dispersive X-ray spectroscopy (EDS). The infrared spectra of the yarn sample indicate the cellulose origin of the ancient fibers.Article Citation - WoS: 1Sustainability of Traditional Meat Dishes with Fruit(Elsevier, 2024) Yilmaz, Emircan; Yalcin, YavuzThis study investigates the cultural and gastronomic sustainability of traditional meat dishes in Mardin that include fruits. The study employed a qualitative research method and an in-depth interview technique. The data collection tool was a semi-structured interview form that included demographic information in the first part and questions evaluating the cultural and gastronomic sustainability of Mardin's traditional meat dishes, namely I(center dot)ncasiyye, Alluciye, and Firkiye, in the second part. The study presents the participants' experiences cooking traditional dishes such as I(center dot)ncasiyye, Alluciye, and Firkiye. All participants consistently used the main ingredients, including dried black plum, green plum, wild plum, and meat. However, some participants added extra ingredients to enhance the dishes. The study highlights the significance of passing down the preparation of traditional meat dishes to future generations, contributing to their cultural and gastronomic sustainability.Article Relationship Between Cryptocurrency Trading, Hopelessness, and Financial Well-Being: A Cross-Sectional Study Among Physicians(Int Scientific Information, Inc, 2025) Donmezdil, Suleyman; Uyar, BetulBackground: Cryptocurrencies trade continuously on highly volatile markets and can elicit emotionally driven, gambling-like behaviors. Physicians experience high occupational stress and burnout, potentially predisposing them to risky financial activities. We examined whether hopelessness and perceived financial well-being are associated with problematic cryptocurrency trading among physicians. Material/Methods: In a cross-sectional online survey, 300 licensed physicians from Diyarbak & imath;r, Turkey, completed the Beck Hopelessness Scale (BHS; score range, 0-20), Financial Well-Being Scale (FWBS; 0-100), and Problematic Cryptocurrency Trading Scale (PCTS; 16-80). Group differences were evaluated with t tests and chi-square tests, and multivariable linear regression models estimated PCTS predictors. Results: Participants' mean age was 39.8 +/- 7.2 years; 70% were male; mean practice duration was 14.1 +/- 6.9 years. Male physicians had higher PCTS scores than female physicians (33.0 +/- 6.8 vs 29.8 +/- 5.9; P=0.03); BHS and FWBS scores did not differ by sex. In regression models, older age ((3=0.32, P=0.04) and male sex ((3=1.45, P=0.02) predicted higher PCTS scores. Hopelessness was positively associated with PCTS ((3=0.80, P=0.001), whereas financial well-being showed a trend toward significance ((3=-0.03, P=0.067). The demographics-only model explained approximately 8% of PCTS variance; the psychosocial model R2=0.35 (P<0.001). Conclusions: Among physicians, male sex, older age, and higher hopelessness are independently associated with problematic cryptocurrency trading, while perceived financial well-being is not clearly protective. Targeted institutional interventions (financial literacy and stress-management programs) may mitigate compulsive trading and support physician well-being.
