Aydin, Sevinç
This study was designed to observe the effects of sodium tetraborate on preventing lead metal toxicity damage to fatty acids in rat heart tissue. After the heart tissues were homogenized with Tris-HCl buffer, the separated pellet part was prepared for fatty acid analysis. The fatty acids in the obtained lipid extract were converted to methyl ester form and analyzed with SHIMADZU GC 2010 PLUS gas chromatography. When comparing the lead group with the lead + sodium tetraborate group, partial increases were observed in saturated fatty acid levels such as myristic acid (14:0), pentadecanoic acid (15:0), and palmitic acid (16:0), while varying increases were seen in some monounsaturated fatty acid levels such as palmitoleic acid (16:1, n-7), and oleic acid (18:1, n-9). Moreover, demonstrated varying levels of increases in all polyunsaturated fatty acids excluding the arachidonic acid (20:4, n-6) and adrenic acid (22:4, n-6) fatty acids. As the most notable fatty acid change in our study, arachidonic acid (20:4, n-6) fatty acid increasing in the lead group while decreasing in the sodium tetraborate group demonstrates that sodium tetraborate decreased the negative effects of oxidative stress on fatty acids. The results of this study provide supporting evidence for the potential use of sodium tetraborate in drug design to prevent the toxic effects of lead.

This study developed an exploratory heuristic decision-support framework for dynamically regulating instructor visibility in instructional videos based on learners’ eye-tracking data. Eye-movement data were collected from 40 university students using a Tobii Pro Fusion while viewing 16 explanatory and procedural instructional videos. Instructor and Learning Content Areas of Interest were analyzed using normalized eye-tracking indicators. Descriptive analyses were complemented by Wilcoxon signed-rank tests, binary logistic regression, and receiver operating characteristic (ROC) analyses. Learners allocated significantly greater visual attention to learning content than to the instructor across both video types. Logistic regression identified instructor attention percentage, visit-related metrics, and blink frequency as significant predictors of visibility decisions. ROC analysis showed that instructor attention percentage provided the highest discriminative performance, with an optimal threshold of approximately 30%. Findings suggest that instructor visibility may be particularly appropriate during introductory, summary, and conceptually demanding segments, providing empirically grounded, attention-aware guidance for adaptive instructional video interfaces.

Okyar, Ferit; Kemer, Duygu
Background Children with Down syndrome (DS) often have feeding problems, which may negatively affect the quality of life (QoL) of their parents. This study aimed to identify feeding problems in children with DS and to examine the relationship between these feeding problems and parental QoL. Methods This cross-sectional study included 105 parents of children aged 10–18 years with DS in Turkey. Data were collected through face-to-face interviews using the Screening Tool of Feeding Problems (STEP) and the SF-36 Health Survey (SF-36). Results This study indicated that the mean STEP scale scores were below the average level across all frequency × severity subscales. Parents' mean scores on the SF-36 QoL scale were above the reference mean (x̄ = 50.00) for the physical functioning, vitality, mental health, social functioning, pain, and general health perception subscales, whereas scores for the physical role limitation and emotional role limitation subscales were below the reference mean. In this study, a moderate negative correlation was found between STEP subscale scores and parents' mean SF-36 subscale scores ( p ≤ 0.05). Conclusions In this study, a significant negative correlation was found between the STEP subscale scores and the parents' mean SF-36 subscale scores. Implications to practice: Routine feeding assessments using the STEP scale should be conducted for children with DS, and nurse-led parent education programs addressing feeding problems should be implemented.

Özdemir, Osman; Yücel, Halit Lutfi; Kahraman, Gökhan
This study experimentally investigates the use of several passive cooling techniques to enhance the electrical performance of photovoltaic (PV) modules under high ambient summer temperatures in Elazığ, Turkey. Throughout the trial period of July, August, and September, a system comprising four photovoltaic panels, one designated as a reference, was developed. The first passive cooling arrangement utilized a paraffin-based phase change material (PCM) RT42HC. In the second configuration, a nano-enhanced PCM (NePCM) composite was employed, prepared by dispersing 1 mass% of Al2O3 nanoparticles into the paraffin matrix and stabilizing them with 3 mass% of sodium dodecyl sulfate (SDS) to ensure homogeneous distribution. The third, hybrid configuration integrated 14 graphene-coated parabolic pin-tipped fins mounted externally onto the aluminum enclosure housing the NePCM composite. Experimental results demonstrated that the implemented passive cooling techniques markedly decreased the panel surface temperature, thereby enhancing electrical power output and photovoltaic efficiency. The hybrid graphene-coated fin-NePCM system demonstrated superior performance, achieving a maximum surface temperature reduction of 12.65 °C, a sustained electrical efficiency increase of 6–13%, and an average daily electrical energy gain of 26.23 Wh day−1 compared to the reference module. These findings demonstrate that the integrated hybrid design is an effective and reliable passive cooling method for sustaining photovoltaic system performance under hot climate conditions.

Gülmez, Nihan; Kanellopoulos, Antonios
The demand for sustainable construction materials promotes the use of industrial waste in cement-based systems. This study examines mortars incorporating fly ash (FA) (0%, 7.5%, and 15%), waste glass, and chromite aggregates for mechanical and durability performance. Specimens underwent compressive strength, freeze–thaw, high-temperature, sulfate attack, and ultrasonic pulse velocity tests, while microstructure was characterized by x-ray diffraction, thermogravimetric analysis, and scanning electron microscopy–energy-dispersive spectroscopy. Mortars with 7.5% FA exhibited relatively high compressive strength and improved freeze–thaw resistance. The combined use of chromite and FA improved strength retention at 800°C, reaching 23 MPa with 7.5% FA and 50% chromite. The greatest sulfate resistance occurred in mortars containing 15% FA and 15% waste glass, maintaining compressive strengths of 61 and 70.9 MPa after MgSO4 and Na2SO4 exposure, respectively.

Anesthesia practices in aquaculture are important for preventing potential stress in fish. For this purpose, interest in natural anesthetic agents as substitute for currently used synthetic anesthetics has increased. In this context, the present study demonstrated the anesthetic efficacy of citronella oil (Cymbopogon nardus) in rainbow trout (Oncorhynchus mykiss) individuals. Based on an artificial neural network (ANN) model derived from preliminary studies, the optimal anesthetic concentration for rainbow trout individuals was estimated as 90 μL L−1. Validation of the concentration predicted by ANN revealed no time-dependent hematological or histological effects on fish to citronella oil. Furthermore, biochemical tests revealed that the partial post-anesthesia increase in ALT and AST values was transient and negligible in light of histological findings. Although oxidative stress was observed during the acute period, the enzymatic activity of SOD and CAT effectively reduced the oxidative damage, demonstrating their role in protecting the fish from oxidative stress. The antioxidant activity observed was temporary, returning to baseline levels without any accompanying tissue damage at the tested concentration. Behavioral monitoring further indicated a swift reduction in motor activity followed by a smooth recovery process, with no evident signs of stress or avoidance behaviour. Overall, these results position citronella oil as a promising natural anesthetic for rainbow trout under the studied parameters. That said, further studies involving various solvents, temperature ranges, and fish species are necessary to comprehensively establish its efficacy and safety.

Karasu, Yakup; Dogan, Adnan; Aykut, Semih; Ozturk, Burhan; Aglar, Erdal
Grapevine (Vitis vinifera L.) is an important fruit crop with considerable morphological and biochemical diversity, and autochthonous genotypes represent valuable genetic resources for breeding and conservation programs. Many local varieties remain underexplored in terms of pomological and antioxidant traits. Eighteen indigenous grape genotypes collected from Muş province (Eastern Anatolia, Türkiye) were evaluated using morphological and biochemical parameters, including berry traits, phenolic composition, vitamin C, and antioxidant activity. Multivariate analyses including PCA, HCA, and Pearson correlation were performed to classify genotypes and determine trait relationships. The first two PCA components explained 51.9% of the total variation. Antioxidant-related traits mainly contributed to PC1, whereas berry size and anthocyanin content influenced PC2. HCA grouped the genotypes into distinct clusters according to antioxidant capacity and pomological characteristics. Correlation analysis showed significant positive relationships among antioxidant-related parameters. Berry size traits were positively correlated with each other, but negatively associated with seed number and skin thickness. The combined use of pomological, biochemical, and multivariate analyses proved useful for genotype classification. The identification of antioxidant-rich genotypes may support future breeding and conservation studies. The results highlight the importance of indigenous grape germplasm for sustainable viticulture.

Karaaslan Ayhan, Nagihan; Seker, Seda
In this study, magnetic iron oxide@neodymium/alginate (Fe3O4@Nd/Alg) beads were prepared by ionic crosslinking with neodymium (Nd) ions, then subjected to heat treatment, and for the first time, effective removal of Reactive Blue 4 (RB 4) dye from aqueous solution was achieved with these beads. For this purpose, ideal adsorption conditions that significantly affect the removal of this dye were determined. The ideal adsorption conditions were determined as pH:5, contact time (t):60 min, amount of magnetic Fe3O4@Nd/Alg bead (m):10 mg, initial RB 4 dye concentration (C0):25 mg/L, temperature (T): 25 °C. Adsorption isotherm, kinetic and thermodynamic studies were carried out under the ideal adsorption conditions. The adsorption data was found to completely follow Langmuir model for RB 4 dye and the maximum adsorption capacity of RB 4 was found to be 263.16 mg/g. The adsorption kinetic data was found to be compatible with pseudo-second order and adsorption processes were explained by intraparticle diffusion. In adsorption thermodynamics studies, it has been determined that the nature of the adsorption reaction is spontaneous, endothermic and with increasing randomness. Furthermore, reuse studies of magnetic Fe3O4@Nd/Alg beads were carried out and it was determined that these beads could be used successfully up to 10 adsorption/desorption cycles.

Members of the Ajuga genus are of significant interest due to their traditional applications in various countries, and have therefore been the subject of phytochemical research investigating their natural bioactive compounds. The aim of this study was to determine the chemical composition and biological activities of various Ajuga vestita extracts (ethyl acetate, ethanol, ethanol/water and water). The biological effects assessed included antioxidant, enzyme inhibition and cytotoxic activities. The extracts were chemically profiled using ultra-high-performance liquid chromatography – electrospray ionization – quadrupole time-of-flight mass spectrometry (UHPLC-ESI-QTOF-MS), which identified 121 compounds, including iridoids, flavonoids, and phenolic acids. The ethanol/water extract exhibited superior radical scavenging activity (2,2-Diphenyl-1-picrylhydrazyl (DPPH): 43.13 mg Trolox equivalent (TE)/g; 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS): 45.37 mg TE/g) and reducing power (cupric reducing antioxidant capacity (CUPRAC): 103.43 mg TE/g; ferric reducing antioxidant power (FRAP): 45.29 mg TE/g). Regarding enzyme inhibition, the ethanol extract exhibited the greatest inhibition of acetylcholinesterase (AChE), butyrylcholinesterase (BChE), glucosidase, and tyrosinase, whereas the ethyl acetate extract was most effective against amylase. Regarding cytotoxicity, the ethyl acetate extract exhibited the strongest effect, significantly reducing cell viability in all cell lines and having a particularly strong impact on murine bone marrow stromal (S17) cells, with viability at 30.8 ± 2.7% at a concentration of 100 µg/mL. By contrast, the aqueous extract exhibited low cytotoxicity, maintaining high cell viability (over 94% at 50 µg/mL and over 74% at 100 µg/mL). Additionally, network pharmacology, molecular docking and molecular dynamics simulations were employed to investigate the multi-target mechanisms and binding stability of A. vestita phytochemicals. These findings provide new, detailed insights into A. vestita and suggest its potential as a raw material for developing health-promoting nutraceutical and pharmaceutical products.

Topcuoğlu, Ceyhun; Ozel, Alp; Tutun Yumin, Eylem; Sertel, Meral; Tug, Tuncer
BACKGROUND: Chronic obstructive pulmonary disease (COPD) is associated with respiratory muscle dysfunction, postural alterations and balance impairment. However, the impact of respiratory muscle weakness on postural control and its relationship with spinal curvature and mobility remain insufficiently clarified. OBJECTIVES: The objectives of this study were to compare postural control in individuals with COPD with and without respiratory muscle weakness; to examine the relationship among spinal curvature, spinal mobility, postural control and respiratory muscle strength; and to determine the effect of respiratory muscle strength on postural control. METHODS: This cross-sectional study included 41 clinically stable individuals with COPD aged 40–75 years. Respiratory muscle strength was assessed using a mouth pressure measurement device. Postural control and balance were evaluated with the Biodex Balance System and functional tests. Higher stability index values indicate greater postural sway and poorer balance performance, whereas lower values reflect better postural stability. Spinal curvature and mobility were assessed using the Spinal Mouse®. RESULTS: Individuals with respiratory muscle weakness showed significantly higher overall, anterior–posterior and medial–lateral stability indices, as well as worse eyes-open and eyes-closed firm-surface indices compared to those without weakness (p < 0.05). In participants with severe and very severe COPD, thoracic kyphosis angle was significantly associated with MIP, MIP% and multiple balance indices under different surface and visual conditions (p < 0.05). CONCLUSIONS: Respiratory muscle weakness is associated with impaired postural control and balance performance in individuals with COPD, and thoracic spinal curvature appears to be linked to both respiratory muscle strength and balance outcomes.

Ataş, Kübra; Mutlu, Ebru Kaya
Background: Despite the widespread use of exercise in managing tension-type headache, there remains a lack of research on the effectiveness of combined structured exercise programs. The aim of this study was to investigate the effects of a structured exercise program versus aerobic exercise of equal duration on tension-type headache (TTH). Methods: Fifty-four female participants aged between 18 and 55 years were randomised to receive a 12-week exercise program, conducted twice a week for 45 min per session. The Structured Exercise Group (SEG) participated in a combination of aerobic, strengthening, and stretching exercises, whereas the Aerobic Exercise Group (AEG) performed only aerobic exercises. The primary outcome measure was the Headache Impact Test (HIT-6), a quality-of-life questionnaire. Secondary outcome measures included headache intensity, disability level, pressure pain threshold, proprioception, muscle strength, cervical posture, exercise capacity, anxiety, and depression. Results: Both groups showed statistically significant improvements in quality of life, pain intensity, disability, anxiety, depression, exercise capacity, pressure pain threshold, and proprioception (p < 0.05). Between-group comparisons revealed that the SEG demonstrated significantly greater improvements in quality of life, pressure pain threshold, proprioception, muscle strength, and posture (p < 0.05), whereas the AEG showed superior gains in exercise capacity (p < 0.05). Conclusion: Both exercise programs appear similarly effective for self-reported outcomes. Based on clinical measurement results, we recommend incorporating strengthening and stretching exercises into the aerobic exercise program and extending the duration to 12 weeks for additional benefits. Significance Statement: This study highlights the clinical value of supervised, physiotherapist-led exercise and the integration of personalised, multi-component strategies in managing tension-type headache. While both structured and aerobic programs improved pain, activity, and participation, the structured approach provided additional benefits in pressure pain threshold, proprioception, muscle strength, and posture. Tailoring interventions to individual clinical needs and extending the duration beyond 8 weeks may further enhance outcomes.

Han, Ayşegül; Pehlivan, Ceren; Konat, Gökhan; Koncak, Ahmet
This study examines the impact of green innovations on environmental sustainability in BRICS-T countries between 2008 and 2021. Using indicators such as renewable energy consumption, R&D investments, industrial design activities, and carbon emissions, the analysis employs both conventional and spatial panel estimation techniques. The findings reveal that investments in renewable energy play a crucial role in reducing carbon emissions and positively contribute to environmental sustainability. However, the effectiveness of environmental innovation policies and R&D expenditures in mitigating emissions remains limited, particularly in the short term. Additionally, industrial design activities are identified as a significant contributor to rising emissions, highlighting the need for a transition toward more sustainable industrial practices. The study also uncovers spatial dependencies among countries, demonstrating that carbon emissions in one nation can influence those in neighboring countries, emphasizing the necessity of regional cooperation and coordinated environmental policies. Based on these findings, the study provides policy recommendations to enhance the effectiveness of green innovations, stressing the importance of increasing investments in renewable energy, aligning R&D expenditures with environmentally sustainable technologies, and promoting sustainable industrial practices across BRICS-T countries.

Green synthesis is a prominent procedure used to easily and environmentally friendly fabricate nanostructures and nanoparticles (NPs), without complex instrumentation, intricate procedures, and harmful chemicals. This study investigated the green synthesis of silver NPs (AgNPs), with Aronia melanocarpa fruit extract as the reducing agent. Following synthesis optimization, AgNPs were characterized using a range of analytical techniques, including UV–Vis, XRD, SEM-EDX, BET, and TEM analyses. Based on the characterization results, an Ag/AgCl hybrid structure was formed. The Ag/AgCl NPs obtained were utilized as adsorbents to remove Cd(II) and Pb(II) heavy metals. The experimental factors that were optimized included pH (5.5), sample volume (5 mL), eluent type and concentration (2 M HNO3), adsorbent amount (5 mg), and extraction time (30 min). Under optimized conditions, the limits of detection were determined to be 9.6 and 4.8 µg/L for Pb(II) and Cd(II), respectively. These limits were established within a concentration range of 50–3,000 µg/L.

Ataş, Kübra; Kaya Mutlu, Ebru
Introduction: Primary headaches, particularly migraine and tension-type headaches, as chronic and painful conditions, have a significant impact on individuals' health and overall quality of life, including aspects such as sexual health parameters. Objectives: The aim of this study was to review observational studies and to summarize the presence of sexual dysfunction in patients with primary headache and to discern whether it is more common in patients with primary headache than in healthy control subjects. Methods: Observational studies published between January 1, 2000, and May 21, 2023 were searched in Medline (PubMed), Web of Science, Scopus, and EBSCO. This review included 23 observational studies that evaluated sexual dysfunction with or without comparison with healthy control subjects. Results: As a result, the mean Female Sexual Function Index score, a score of <26.55 indicating sexual dysfunction, ranged from 19.25 ± 8.18 to 27.5 ± 7.5 in patients with primary headache. The prevalence of sexual dysfunction and erectile dysfunction was found to be between 10.7% and 93.75% in female patients and between 54.83% and 80% in male patients. Both migraineurs and tension-type headache sufferers had statistically significantly lower sexual function scores in females and lower erectile function scores in males compared with healthy control subjects. Conclusion: Sexual function is significantly affected in patients with primary headache, which is a chronic painful disorder. Therefore, it is very important to ask these patients about their sexual health and, if necessary, to seek support from a sexual health professional. Additionally, future studies may prioritize tension-type headaches and male patients due to the limited amount of research available on these subjects.

Uyanik, Hakan; Kokum, Mehmet; Senturk, Erman; Freeshah, Mohamed; Ozcelik, Salih T. A.; Halil Akpinar, Muhammed; Celik, Serenay; Sengur, Abdulkadir
This study proposes a novel deep learning approach for predicting significant earthquakes (Mw ≥ 5.0 ) in Turkey using ionospheric Total Electron Content (TEC) data and space weather indices. ConvMixer is a lightweight CNN architecture that blends spatial and channel information using depthwise convolutions and pointwise layers. Inspired by vision transformers, it offers efficient image classification with fewer parameters and high performance. We developed a multi-input one-dimensional convolutional mixer (MI-1D-ConvMixer) model to classify TEC data from the preceding five consecutive days as either precursory to an earthquake on the 6th day or normal. The model incorporates six inputs: five 1D TEC signals and one 1D space-weather index array, including the global geomagnetic index (Kp), storm duration distribution (Dst), sunspot number (R), geomagnetic storm index (Ap-index), solar wind speed (Vsw), and solar activity index (F10.7) are also utilized to reveal non-seismic related pre-earthquake ionospheric variations. Our methodology involves two stages: 1) a preprocessing stage to enhance TEC signals and 2) an end-to-end training of the MI-1D-ConvMixer model. The model architecture features depth-wise and point-wise convolutions with patch embedding, utilizing uses four tunable hyperparameters: network depth, hidden dimension size, kernel size, and patch size. We used 196 earthquakes data from Turkey from 2010-2023, and TEC data from the TNPGN-Active GNSS stations. The dataset was split into 75% for training and 25% for testing. Performance metrics, including classification accuracy, sensitivity, specificity, and F1-score, are used for evaluation. Our model achieved a classification accuracy of 97.49%, demonstrating its potential for earthquake prediction systems. This research contributes to the field by introducing a novel deep learning architecture specifically designed for integrating TEC and space weather data for earthquake prediction. Future work should focus on validating the model’s performance in different geographical regions and investigating its limitations.
