Daştan, Buket; Ünal, Hediye
PURPOSE: The current randomized controlled trial evaluated the effect of a virtual reality (VR) glasses intervention on mild cognitive impairment (MCI) in older adults. METHOD: This study was conducted with 24 participants (12 in the intervention group and 12 in the control group) admitted to a neurology outpatient clinic. Participants completed a descriptive information form, the Mini-Mental State Examination, and Montreal Cognitive Assessment. The intervention group watched VR videos 3 days per week for 4 weeks, whereas the control group received no intervention. RESULTS: Participants in the VR intervention group showed improvement in MCI, whereas no significant change was observed in the control group. CONCLUSION: VR interventions may serve as effective tools to enhance cognitive functions in older adults with MCI. Expanding the intervention content and tailoring applications to address specific symptoms may yield more comprehensive results.

Okur, Süheyb; Bayraktar, Bülent
Background: This study aims to examine the acute neurobiological effects of reciting the Quran from the Mushaf on salivary BDNF, Apelin, and Cortisol levels and their relationship with emotional state. Methods: The study employed a randomized pre-test post-test control group design conducted in Türkiye. The sample consisted of 100 healthy theology students (50 females, 50 males) aged 18–25, proficient in reciting the Quran in accordance with Tajweed rules. Participants were randomly assigned to either the experimental group (reciting the first nine verses of Surah Al-Imran, n = 50) or the control group (standardized passive resting, n = 50). Salivary BDNF, apelin, and cortisol levels were measured using the ELISA technique before and after the intervention. Emotional states were assessed using the Mood Scale and the Psychological Well-being Scale. Results: The experimental group exhibited a statistically significant increase in mean salivary BDNF and apelin levels and a significant decrease in cortisol levels following recitation compared to the passive control group (p < 0.05). In terms of gender, no statistically significant differences were observed in biomarker responses (p >.05). Correlation analysis revealed a significant “biological reciprocity,” where cortisol showed a negative correlation with apelin (r = -0.436, p < 0.001) and BDNF, while correlating positively with negative emotions. Conclusions: Reciting the Quran aloud acts as a rapid psychophysiological intervention that downregulates the HPA axis (reduced cortisol) and upregulates neurotrophic factors (increased BDNF and apelin). These findings suggest that structured recitation functions as a restorative neuroplasticity practice, promoting biological stress resilience associated with psychological well-being.

Gökcan, Hande; İspirli, Hümeyra; Dertli, Enes
Glucansucrases catalyze the production of α-glucans using sucrose as substrate with distinct physicochemical characteristics originates from mainly the type of linkages, degree of branching and molecular mass. New forms of α-glucans can be produced by applying specific mutations to glucansucrases. In this study, a single and double mutation at Leu933 and Leu935 sites of glucansucrase E81 was applied and L933I and L933I-L935F sites modified glucansucrase was obtained. Structural characterisation of bioengineered α-glucans revealed that ratio of (1 → 3):(1 → 6) linked α-Glc units altered at L933I whereas no (1 → 3)-linked α-Glc units were presented for L933I-L935F modified glucansucrase detected by NMR analysis. Both bioengineered α-glucans had lower molecular weights in comparison to glucan E81 detected by GPC analysis. TGA and DSC analysis were applied to detect the thermal profiles of bioengineered α-glucans whereas FTIR and XRD analysis were applied to determine the alterations in the structural and physical nature of the bioengineered α-glucans, respectively. Finally, SEM and AFM analysis were applied to explore the morphological modifications of the bioengineered α-glucans. This study provides a better understanding for the potential role of final glucan structures on their physicochemical characteristics. Keywords: glucansucrase; carbohydrate engineering; mutation.

Hypericum Tourn. ex L. species exhibit well-documented neuropsychopharmacological activities, yet the central effects of Hypericum olympicum L. remain unknown. Given the frequent comorbidity of depressive symptoms and pain, this study aimed to characterize, for the first time, the antidepressant-like and antinociceptive profile of H. olympicum in mice. A methanolic extract of the aerial parts (HoE) was prepared, and its major phenolic constituents were identified by LC-MS/MS. At behaviorally active doses, HoE (2.5 and 5 mg/kg, i.p.) did not impair motor coordination in the Rota-rod test, in contrast to diazepam (2 mg/kg, p.o.), indicating the absence of neuromotor confounding effects. In both the tail suspension test (TST) and the modified forced swim test (MFST), HoE significantly reduced immobility, with effects comparable to those of fluoxetine (30 mg/kg, p.o.). In the MFST, increased swimming behavior without changes in climbing suggested a predominantly serotonergic component. HoE also produced marked antinociceptive effects in multiple nociceptive models. It increased response latencies in the hot-plate, tail-immersion, and tail-clip tests, reflecting activity in supraspinal and spinal thermal and mechanical nociceptive processing. In addition, HoE significantly reduced acetic acid-induced writhing, indicating visceral antinociceptive activity. Morphine (10 mg/kg, i.p.) served as the positive control in pain assays. LC-MS/MS analysis indicated the presence of major phenolic constituents, including hyperoside, myricetin derivatives, caffeoylquinic acid derivatives, a luteolin/kaempferol-type glucoside, and a biflavone of the biapigenin/amentoflavone type. These findings suggest that HoE possesses dual antidepressant-like and antinociceptive properties and support its further evaluation for disorders at the affect–pain interface.

This study experimentally investigates the thermal and electrical performance, economic feasibility, and environmental impacts of a hybrid energy system integrated with a parabolic trough collector (PTC) and thermoelectric generator (TEG). In the established system, solar energy is converted into electrical and thermal energy using a steam turbine and TEG. Experimental data indicate that the system operates with an average efficiency of 71.44%, which varies depending on the intensity of solar radiation. The overall energy efficiency of the system is calculated as 14.51%. In the economic analysis, the payback period of the designed system is approximately 5.4 years, while the levelised cost of energy production (LCOE) is calculated to be 0.075 USD kWh−1. The environmental assessment indicates that the system can prevent 356.18 kg of CO2 emissions annually and save approximately 1499.72 L of water. These findings demonstrate that hybrid systems offer an economically and environmentally sustainable and efficient alternative to energy production.

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.

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.

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.

Yıldız, Ümit
This study investigates the causal relationship between geopolitical risks and global inflation and examines whether this causal effect, if any, is persistent. To this end, the stationarity of the annual Geopolitical Risk Index (GPR) and global inflation series for the 1985–2024 period was first analyzed using the Lee and Strazicich (2003) two-break unit root test, which concluded that the series are stationary at levels. Subsequently, the data were analyzed using a stationary frequency domain causality approach, revealing a unidirectional causal relationship running from GPR to global inflation at both low and high frequencies. The causality identified at low frequencies indicates that this causal effect is permanent. The findings of the study suggest that mitigating geopolitical risks is of vital importance in the fight against global inflation.

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
