ULUSU, Funda; OZEL, Sultan Suleyman; Sarilmaz, Adem; ULUSU, Yakup
This pioneering study presents the synthesis and comprehensive evaluation of bare and metal-doped Ag₂S nanocrystals (NCs) as multifunctional agents with potential applications in antibacterial, antioxidant, and anticancer therapies. The incorporation of manganese, nickel, cobalt, and zinc into Ag₂S NCs resulted in a notable enhancement of their bioactivity, representing a novel approach in nanomaterial design. The antibacterial assessments revealed that Mn:Ag₂S NCs were the most potent candidate, exhibiting exceptional activity against S. aureus and E. coli, with the lowest MIC values recorded at 1.28 mg/mL and 1.08 mg/mL, respectively. The antioxidant studies demonstrated that the Mn:Ag₂S NCs exhibited remarkable free radical scavenging and ferric reducing capacities, with the lowest IC50 values (22.69 µg/mL for DPPH and 61.31 µg/mL for FRAP) underscoring their potential to mitigate oxidative stress. Importantly, cytotoxicity assays revealed that Ni:Ag₂S and Mn:Ag₂S nanocrystals selectively inhibited the proliferation of human colon cancer cells (HT-29), achieving IC50 values of 61.51 µg/mL and 90.12 µg/mL, respectively. Furthermore, these NCs demonstrate reduced toxicity towards mouse fibroblast cells (L929). This selective cytotoxicity indicates the potential of these agents in targeted cancer therapies, thereby reducing damage to healthy tissues. To the best of our knowledge, this is the first study to systematically explore the synergistic effects of metal doping on the multifunctional properties of Ag₂S NCs. These findings provide a robust basis for further in vivo studies and offer new avenues for the development of safe and effective nanomaterials in biomedical applications, particularly as antimicrobial, antioxidant, and anticancer agents.

Ayata, Ümit; Peker, Hüseyin; Ulay, Göksel; Çamlıbel, Osman; Atilgan, Abdi
It is known that blue stain causes a loss of price value for Scots pine wood in the wood trade due to the visual defects it creates. In this study, color parameters [red color tone (a*), lightness (L*) value, yellow (b*) color tone, tone angle (h°) value, and chroma (C*) value], whiteness index (WI*) values, and glossiness measurements [at angles of 20°, 60°, and 85°] were compared in Scots pine (Pinus sylvestris L.) wood with normal and blue rot conditions. According to the color parameters obtained, it was determined that the L* value decreased by 11.43%, a* by 79.95%, b* by 28.86%, and C* by 32.75%, while the h° value increased by 17.74%. With the blue coloration, decreases were observed in the 20° glossiness values measured in the ⃦ and ⊥ directions, while increases were observed in the 60° and 85° glossiness values measured in the ⃦ and ⊥ directions. With the blue coloration, decreases of 12.86% in the ⊥ direction and 29.87% in the ⃦ direction in the WI* values were observed. According to these results, it was determined that the wood material with the blue coloration disease had a darker color.

Propolis is a chemically complex bee product whose biological properties depend on its botanical and geographical origin. However, little is known about how gastrointestinal digestion affects its phenolic profile and bioactivity. In this study, twelve propolis samples from eight countries were evaluated for phenolic and flavonoid contents, antioxidant capacity (FRAP, ABTS+•), and urease inhibition before and after simulated gastric digestion. RP-HPLC–PDA identified 26 phenolic compounds showing substantial compositional diversity. Turkish Bolu propolis retained the highest post-gastric FRAP value, while several samples (BBP, AFP) maintained or enhanced urease inhibition. PCA and HCA highlighted origin-dependent differentiation, identifying digestive stability as a key variable for functional potential.

Ozkat, Erkan Caner; Abdioglu, Murat; Ozturk, U. Kemal
This study presents a finite element analysis (FEA)-driven optimization for the design of an electrodynamic levitation (EDL) system incorporating permanent magnet Halbach arrays (PM-HAs). The primary objective is to maximize the net force difference between lift (Fy) and drag (Fx) forces under realistic physical and manufacturing constraints. The nonlinear electromagnetic behavior of the EDL system is modeled using high-fidelity FEA, capturing the complex interaction between the PM-HA and a conductive plate. At each iteration of the population-based optimization algorithm, full magnetoquasistatic simulations are performed to ensure a physically accurate evaluation of key performance metrics. A comprehensive parametric study involving 256 distinct PM-HA configurations reveals a non-monotonic relationship between the number of magnets and levitation performance, highlighting the critical role of magnetic field distribution. Configurations with 9 to 11 magnets achieve the highest net levitation force. The optimization results indicate that the optimal configuration includes four horizontally aligned permanent magnets (PMs) with a width of 74.00 mm and three vertically aligned PMs with a width of 74.67 mm, along with a 7 mm thick conductive plate having a conductivity of 5 ×107 S/m. This design delivers a maximum lift force of 3550 N and a minimum drag force of 279 N at 100 m/s. The findings demonstrate that effective EDL system design requires a carefully arranged magnet configuration rather than a simple maximization of magnet count or size. The proposed FEA-guided framework offers a robust and scalable methodology for the optimization of high-performance Maglev systems.

Köktürk, Seda Nur; Yardımcı, Hülya
Growing concerns over environmental sustainability and health have increased the demand for sustainable diets. Advances in artificial intelligence (AI) offer new opportunities for diet planning. Evaluating the nutritional adequacy and environmental impact of AI-generated sustainable diets is essential. This study aimed to compare the nutritional quality and ecological footprints of sustainable diets created by four popular AI tools (Gemini, Copilot, ChatGPT, and Grok). Each AI tool generated a sustainable diet plan for a healthy adult woman. Diets were evaluated for energy, nutrient content, antioxidant capacity, glycemic index, protein quality, fatty acid profiles, Healthy Eating Index-2015 scores, and ecological footprints. All diets showed low ecological footprints but did not meet energy targets (1800 kcal/day). Gemini had the most sustainable composition. Vitamin B12 was consistently below recommended levels in diets from Gemini, Copilot, and ChatGPT. All diets had adequate carbohydrate, protein, fat quality, and overall diet quality. Carbon footprint associated with protein, energy from protein, cholesterol, pyridoxine, folate, and vitamin C. Water footprint was linked to multiple nutrients, and fruits, meat, poultry, and fish; vegetable intake correlated with carbon footprint. AI-assisted diets have potential for sustainability but nutritional completeness concerns remain, especially for vulnerable groups. Further studies comparing AI and dietitian plans are needed to assess long-term effects.

Kul, Murat; Hazar, Emre Berk
This study aimed to compare acute muscle swelling and echogenicity responses induced by repeated arrow shooting in experienced and amateur traditional Turkish archers, and to examine the influence of training level using ultrasonography. Twenty-four male athletes (12 experienced, 12 amateur) performed 105 arrow shots. Pre- and post-measurements of upper-extremity muscle thickness (MT) and echogenicity were collected. Data were analyzed using repeated-measures analysis of variance (ANOVA) and paired t-tests. Both groups showed significant increases in MT, particularly in experienced archers. Echogenicity increased in several muscles, notably the supraspinatus, brachialis, pronator teres, and brachioradialis. The lack of strong correlation between MT and echogenicity suggests that these parameters reflect distinct acute muscular responses. In conclusion, training level influences acute muscular adaptations to shooting, and certain muscles may require targeted protection to prevent overuse injuries. This study provides the first ultrasonographic evaluation of these responses in traditional Turkish archery.
- MakaleYalnız künye2026Scopus SJRQ2Investigation of magnetic levitation performance in Ag-added DyBa2Cu3O7-δ superconductors fabricated by single-direction melt growth (SDMG) method
Doğruer, M.; Abdioğlu, M.; Motoki, T.; Ozturk, U. Kemal
Abstract This study investigates the magnetic levitation and guidance characteristics of Ag-doped DyBa2Cu3O7-δ superconducting bulks, synthesized by the single-direction melt growth (SDMG) technique. The levitation force, vertical stiffness and lateral guidance force are measured at varying cooling heights (CHs) of 5 mm, 25 mm and 50 mm, with a constant working height (WH) of 5 mm for lateral force measurements. DyBa2Cu3O7-δ samples are cooled using liquid nitrogen (77 K) and thermal stabilization is achieved before force data collection. Results show that levitation forces increase with CH, while the levitation force curves exhibit both attractive and repulsive behavior depending on the CH. The lateral guidance force is higher for the Ag2 sample than for the Ag1 sample and decreased as the temperature decreased. Vertical stiffness also increased with CH and decreased as the levitation gap decreased, confirming heightened guidance forces at smaller distances. The flux density distributions, including both lateral ( B x ) and vertical ( B y ) components, are found to significantly impact the levitation and guidance force performance. Specifically, configurations with concentrated B x gradients improved levitation stability, while configurations with distributed B y led to stronger guidance forces. These findings underscore the importance of optimizing the PMG design to balance B x for levitation and B y for guidance in superconducting systems.

Ari-Arat, Ceren; Tutkun, Cansu
The aim of this study was to examine the associations between preschool children’s perceived capabilities, perspective-taking skills, and behavioral intentions toward peers with special educational needs. The sample consisted of 193 preschool children aged 4 to 6 years, selected through convenience sampling from early childhood education centres in Bayburt, Türkiye. A quantitative cross-sectional design was employed. Data were collected using the Child Information Form, the Perceived Capabilities Scale, the Behavioral Intentions Scale, and the Child Perspective-Taking Test. Data collection was conducted in one-on-one sessions over two meetings per child, with an average duration of 18 min. Small but statistically significant positive associations were observed between children’s perceived capabilities and their behavioral intentions across the three peer conditions (r =.283-0.289, p <.01). Small associations were also observed between selected perspective-taking components and behavioral intentions in the bivariate analyses; however, none of the perspective-taking components remained significantly associated with behavioral intentions after the other variables were taken into account. Across the three regression models, perceived capabilities were the only variable that remained significantly associated with behavioral intentions (β = 0.268-0.289, p <.001). The regression models explained a modest proportion of the variance in behavioral intentions (R² = 0.093-0.106; adjusted R² = 0.074-0.087). Exploratory group comparisons indicated selective differences in perspective-taking according to reported experience with peers with SEN; however, these findings should be interpreted cautiously because experience was measured dichotomously and the direct-experience groups were highly unequal. Girls reported slightly higher behavioral intentions toward peers with physical disabilities than boys (t = 2.318, p =.022), whereas no significant age-related differences were observed.

Kotan, Gökşad Cemil; Aydemir, Şeyma; Bayraktar, Bülent
This study investigated the responses of novel adipokines (irisin, spexin, visfatin), an endoplasmic reticulum (ER) stress marker (GRP78), and traditional metabolic parameters (non-esterified fatty acids (NEFAs), beta-hydroxybutyrate (BHBA), urea, albumin, globulin, total cholesterol) in 360 healthy Brown Swiss dairy cattle. The animals were categorized into 18 subgroups based on pregnancy stages (early, mid, dry), lactation stages (early, mid, late), and body condition scores (BCSs). Serum analyses were performed using ELISA and spectrophotometric methods. Interactions between physiological stages and BCS were highly significant for all measured parameters (p<0.001). Results showed that mean serum levels of spexin (ranging from 14.02 to 36.04 pg mL−1) and irisin increased as pregnancy and lactation progressed. Visfatin levels exhibited a significant increase specifically during the gestation period, peaking during the dry period (24.09 ng mL−1), and maintained a significant increasing trend as lactation progressed toward the late stage (Tables 2, 4). Conversely, GRP78 (peaking at 0.46 ng mL−1), NEFA (peaking at 0.52 mmol L−1), and urea levels peaked during the dry period and early lactation, subsequently decreasing as metabolic stability was achieved. Notably, during the dry period, stress markers rose despite declining albumin and globulin levels (p<0.05). These data indicate that the dry period and early lactation are the most critical phases for metabolic and cellular stress, characterized by lower spexin and elevated GRP78 and NEFA concentrations. The later rise in irisin and visfatin, while BHBA remained within physiological limits, confirms successful metabolic adaptation (p<0.001). In conclusion, the integrated evaluation of these novel biomarkers is anticipated to provide significant contributions to protective strategies and metabolic management in dairy cattle.

Köktürk, Seda Nur; Taş Yıldırım, Esra; Yardımcı, Hülya
Purpose – This study aimed to examine the association between ultra-processed food (UPF) consumption and premenstrual syndrome (PMS) across different body mass index (BMI) categories in women. Design/methodology/approach – A total of 480 women aged 20–49 years participated in the study between May 2024 and May 2025 in 3 cities in Türkiye. PMS symptoms were assessed using the Premenstrual Syndrome Scale (PMSS), and UPF intake was evaluated according to the NOVA classification using a food frequency questionnaire. Anthropometric measurements, including height and body weight, were taken by researchers, and BMI was calculated for each participant. Findings – The mean BMI of the participants was 24.2 ± 4.9 kg/m2, with an average daily UPF intake of 858.0 ± 133.3 g. Higher UPF intake was significantly associated with increased reporting of PMS, with 7.0% higher odds among normal-weight women, 19.0% higher odds among overweight women, and 41.0% higher odds among women with obesity. Moreover, as UPF consumption increased from the lowest (Q1) to the highest quartile (Q4), the odds of experiencing PMS symptoms were 2.65 times (OR: 2.65, %95 CI: 1.52–4.61), 2.85 times (OR: 2.85, %95 CI:1.60–4.95), and 3.07 times (OR: 3.07, %95 CI: 1.71–5.49) higher, respectively (p = 0.001). Research limitations/implications – These findings underscore a significant association between UPF consumption and PMS symptoms, particularly among women with obesity. Given the high prevalence of PMS and its substantial impact on women's well-being, dietary interventions aimed at reducing UPF intake may represent a promising approach for PMS management and prevention. Originality/value – To the best of our knowledge, this study is the first to examine the relationship between UPF intake and self-reported PMS presence across different BMI categories. 2026

Kotan, Gökşad Cemil; Bayraktar, Bülent
Background: This study investigated the effects of dietary graviola (Annona muricata L.) oil extract (GOE) (supplemented at 200, 400, and 600 mg/kg) on the growth performance and circadian rhythm profiles of adipokine, cardiac, and mitochondrial function biomarkers in 48 male Anatolian Merino lambs (2.5 months old). Methods: Lambs were assigned to a control group (G0) or supplementation groups (G200, G400, G600 mg/kg) for a 60-day trial (70 days total). The study was conducted under a 12-h light/12-h dark cycle to ensure controlled environmental conditions. To analyze circadian profiles, blood samples were collected on days 0, 15, 30, 45, and 60 at four time points (07:00, 13:00, 19:00, and 01:00). Serum levels of Apelin, cTnI, BMAL1, MOTS-c, and BMCP1 were measured by ELISA. Data were analyzed using GLM Multivariate analysis (p < 0.05). Results: Key findings showed the G400 dose resulted in the most effective linear increase in live weight and live weight gain by day 60, and had a significant overall effect on live weight (p < 0.05). The G200 dose significantly improved the feed conversion ratio (p < 0.05), while feed consumption was unaffected (p > 0.05). Regarding biomarkers on day 60, the G400 dose effectively modulated BMAL1, MOTS-c, and BMCP1 (peak at 19:00). The G600 dose yielded the best results for Apelin (peak at 19:00) and cTnI (peaks at 13:00 and 07:00). Conclusions: In conclusion, GOE at a dose of 400 mg/kg (G400) not only optimizes fattening performance in Anatolian Merino lambs but also supports metabolic homeostasis by modulating adipokine levels, cardiac function, and mitochondrial biogenesis processes in a manner consistent with the circadian rhythm. These findings demonstrate that the G400 dose is a safe and effective phytogenic strategy for improving animal health and production efficiency.
- MakaleAçık Erişim2026Scopus SJRQ2Investigation of the Effects of Low-Temperature Thermal Treatment Applied to Graphite in Spent Lithium-Ion Anode Recycling
Kara, Adem; Temur, Hakan
As the use of lithium-ion batteries (LIB) increases rapidly, recovery of graphite, the main component of the anode, from spent batteries has become important from environmental and economic perspectives. In this study, an acid leaching step followed by thermal treatment under partial atmosphere at a relatively low calcination temperature was investigated to recover graphite from spent lithium-ion batteries. The molecular and chemical structures of the recovered graphite in all spent anode samples were investigated using FTIR, ICP-MS, XRD, SEM–EDX and TEM–EDX. It was observed that organic impurities and volatile components were largely removed after acid leaching and thermal treatment at 750 °C. In addition, it was observed that graphite layers were rearranged and the distance between the layers decreased under the effect of thermal treatment. Partial atmosphere calcination at 750 °C can be considered as a feasible method for graphite recovery, offering energy efficiency and scalability. However, in an efficient calcination, it is necessary to maintain controlled oxygen levels to prevent excessive graphite loss and to perform preliminary acid leaching to reduce metal impurities. In order to best recycle graphite in waste lithium-ion anode recovery, a balance must be achieved between temperature, energy efficiency and material recovery. Considering this balance, a calcination temperature of 750 °C appears to be preferable for recycling.

Kotaman, Hüseyin; Balcı, Aslı; Tutkun, Cansu; Bayram, Zeynep
This study aims to determine the effect of reading augmented reality (AR)-enriched stories related to sharing on children’s altruistic sharing behavior. In recent years, AR applications have been increasingly utilized in early childhood education to enhance engagement and motivation; however, there is limited knowledge about their impact on children’s social and moral development. Addressing this gap, the present study focuses on how interactive, immersive storytelling environments can foster prosocial behaviors, particularly altruistic sharing, in preschool children. A total of 300 children aged 4–6 from 21 kindergarten classrooms participated in the study. The classrooms were randomly assigned to one of three groups: a group that received an AR-enriched sharing storybook, a group that received a non-AR digital sharing storybook, and a group that received a digital storybook unrelated to sharing (control group). The sharing behavior of the participating children was measured before and after the story sessions using a standardized sticker-sharing protocol. Each child was read the story individually, according to their assigned group. The difference between children’s post-story and pre-story sharing behaviors was calculated, and the sharing differences among the three groups were compared using ANOVA. As a result, it was found that the children who listened to the AR-enriched story about sharing showed a significantly greater increase in sharing behavior compared to the other two groups. These findings highlight the potential of AR-supported storybooks as effective pedagogical tools for enhancing altruistic and prosocial behaviors in early childhood education.

This study compared the antioxidant capacity, total phenolic content (TPC), phenolic composition, lipid oxidation level, and mineral profiles of extracts obtained from four wild hawthorn species (Crataegus tanacetifolia, C. orientalis subsp. orientalis, C. orientalis subsp. szovitsii, and C. monogyna) collected from northeastern Türkiye. Significant interspecific variations were observed in DPPH, FRAP, and CUPRAC assays. While C. monogyna had the highest reducing capacity and TPC, C. orientalis subsp. szovitsii had the highest DPPH activity. Ultra-high performance liquid chromatography coupled to tandem mass spectrometry analysis showed that catechin, epicatechin, chlorogenic acid, and quinic acid were the major phenolics, and were particularly abundant in C. monogyna. Despite having a high phenolic content, C. monogyna had the highest malondialdehyde level, indicating that phenolics alone were insufficient to fully inhibit lipid oxidation. Inductively coupled plasma-mass spectrometry mineral analysis detected high levels of K, Mg, and P in all species. Principal component analysis effectively distinguished the species based on their antioxidant, phenolic, and mineral profiles. Overall, hawthorn fruits were confirmed as valuable sources of natural antioxidants and essential minerals.

Vitamin C equivalency, the cytotoxicity on murine macrophage cells, and the virucidal and antiviral activities of maca (Lepidium meyenii) powder on murine norovirus (MNV) as a norovirus surrogate for human as a foodborne pathogen were studied. The antioxidant capacity of the maca was determined by MTT assay as vitamin C equivalency (VCEAC). The 50% cytotoxic concentration (CC50) was calculated with the linearity of maca concentrations-cell viability. The activities of maca against the virus was determined as the 50% tissue culture infective dose with Spearman–Karber method. The VCEAC of maca linearly increased with the concentration. The non-cytotoxic concentrations of maca were measured on murine macrophage with a CC50 of 5.77 mg/mL and a CC80 of 1.28 mg/mL. As maca reduced the virus titration based on contact time in the virucidal assay in several conditions, it did not significantly inhibit MNV on three infectivity pathways of host cell at non-cytotoxic concentrations of maca. The result of this first study presented that despite its ineffective in the treatment and prophylaxis of norovirus infection, maca might be an alternative food additive and preservative against human norovirus as an important foodborne pathogen causing outbreaks worldwide. © Los autores.
