Yuksel, Duygu; Ozmen, Ozlem
Background: Thyroid hormone deficiencies can disrupt organ functions, significantly impacting the cardiovascular system. Recently, the effects of thyroid hormones on the heart have garnered increased attention. However, most studies are conducted on humans using clinical data, while cellular-level and experimental studies remain limited. Objective: This study aimed to investigate the cardiovascular implications of hypothyroidism and evaluate the impact of caffeine on cardiac health in rats induced with hypothyroidism using propylthiouracil (PTU). Methods: The study involved 60 rats divided into six groups. Group 1 served as the untreated control. Group 2 received PTU for two months to induce hypothyroidism. Group 3 received PTU for one month, followed by caffeine for one month. Group 4 received caffeine for two months. Group 5 received both PTU and caffeine simultaneously for two months. Group 6 received PTU for one month, followed by one month under normal conditions. Results: During necropsy, normal thyroid glands were observed in Groups 1, 4, and 6, enlarged thyroids in Group 2, and smaller thyroids in Groups 3 and 5. Microscopic examination revealed varying thyroid histologies: Group 2 showed significant epithelial cell proliferation and absent colloid, while Groups 3, 5, and 6 had altered yet colloid-containing acini. Macroscopic inspection of hearts appeared normal across all groups. However, histopathological examination revealed significant hyperemia and microhemorrhages in Group 2, contrasting with normal findings in other groups. Immunohistochemical analysis indicated reduced cardiac troponin expression in Group 2, while other groups maintained prominent expression. Additionally, Group 2 displayed increased serum TSH levels and decreased T3 and T4 levels. Conclusion: The findings suggest that administering caffeine alongside or after PTU treatment in rats with experimentally induced hypothyroidism may ameliorate thyroid and cardiac irregularities. This study indicates caffeine's potential in mitigating the adverse effects of hypothyroidism on thyroid and heart health.

Türkkan, Tuğba; Hatipoğlu, Ertuğrul
This study aims to determine the extent of the psychological effects of the Kahramanmaraş earthquake disaster, which is widely regarded as one of the most significant disasters of the century, on young people based on their direct or indirect exposure and to investigate the impact of these issues on life satisfaction. Data were collected from 337 individuals who were continuing their advanced education at a state university in Turkey, using a demographic information form, life satisfaction scale and Depression Anxiety Stress Scales 21. In the analysis of the data, t-test, Pearson correlation test, ANOVA and multiple regression analysis were employed. The results of the analyses indicated that as the intensity of exposure to disaster news increased, the stress, depression, and anxiety levels of the participants also increased. Individuals who experienced the earthquake personally and participated in volunteer aid activities demonstrated higher depression and anxiety scores and DASS21 scale total scores than those who did not directly experience the earthquake but followed the news and those whose relatives experienced the earthquake. There was no significant difference in the intensity of following earthquake news between men and women among the participants. However, it was determined that the intensity of following earthquake news from media and social media tools positively and significantly predicted the life satisfaction of the participants. These findings provide insights for future mental health interventions and social work practices for young people affected by the earthquake.

Kadirov, F.A.; Safarov, R.T.; Gahramanov, M.R.; Maden, N.M.
The South Caspian Basin (SCB) is a geologically complex and diverse region of significant scientific interest due to its hydrocarbon resources and intricate crustal structure. This study provides an updated interpretation of the SCB’s crustal configuration using gravity-derived data, with particular emphasis on delineating Moho depth and the influence of its variations on petroleum basins. The crustal structure of the basin is assessed using Bouguer gravity anomalies, incorporating terrestrial and marine gravity measurements, and processed with spectral analysis methods. Power spectrum analysis was applied to estimate the depths of subsurface mass distributions affecting the gravity field, enabling separation of regional and residual anomalies and providing an initial reference depth of Moho. These results served as input for Parker–Oldenburg inversion, an iterative Fourier-based technique used to model the Moho surface by minimizing discrepancies between observed and calculated gravity anomalies. The integrated approach reveals substantial lateral variations in Moho depth, ranging from approximately 42 km in the Absheron–Prebalkhan zone to about 29 km in the central SCB. Analysis of spatial correlations indicates that oil and gas reservoirs are primarily located in areas where the Moho surface is deeper and along gradient zones marking abrupt depth changes. These findings enhance understanding of the complex tectonic evolution of the SCB and provide valuable constraints for predicting potential hydrocarbon locations in this tectonically active and data-scarce region.

Tuncer, Metin; Tuncer, Gülsüm Zekiye; Turan, Şeyma; Khorshtd, Leyla
Background: Nurse migration contributes to the nursing shortage in developing countries. Understanding nurses' attitudes toward migration and related factors is crucial for policy-making and healthcare workforce planning in Turkey. Aim: This study aimed to investigate the relationship between nurses' attitudes toward migration and their life satisfaction in Turkey. Methods: The study included working nurses with social media accounts on a social media platform in Turkey who followed nursing-related content. A sample of 423 nurses completed an online survey. Independent variables included nurses' sociodemographic characteristics and inclination toward migration, while dependent variables were life satisfaction and migration attitude levels. Data were collected via an online questionnaire, incorporating the Brain Drain Attitude Scale (BDAS) and Life Satisfaction Scale (LSS), between April and May 2023. Results: The study found a negative correlation between nurses' life satisfaction levels and their attitudes toward migration (r = −.349, p <.001). Nurses dissatisfied with their profession (F = 6.575, p <.05), lacking professional support (F = 8.641, p <.05), and lacking social support (F = 6.307, p <.05) scored higher on the BDAS. Conversely, those satisfied with their profession (F = 31.455, p <.05), receiving professional support (F = 26.307, p <.05), and social support (F = 33.990, p <.05) scored higher on the LSS. Conclusion and implications for nursing: The study revealed that decreased life satisfaction among nurses in Turkey correlates with increased migration attitudes. These results underscore the need for strategies to enhance nurses' job satisfaction and support systems to mitigate migration tendencies. This study contributes valuable insights into the high inclination of Turkish nurses toward emigration.

In this study, the effects of cow, buffalo, ewe, and goat milk on the microbiological, physicochemical, sensory properties, and volatile component profile of kefir were examined during storage. Key microbial counts, including lactic cocci, lactic bacilli, and yeast, varied among kefirs, with lactic bacilli and lactic cocci decreasing over time, while yeast counts increased. The titratable acidity ranged from 1.12 to 1.16%, and pH values varied between 4.51 and 4.83. Sensory analysis showed that cow milk kefir received the highest consumer appreciation, while goat milk kefir was least favored. Notably, ewe milk kefir contained the highest benzoic acid content. Principal component analysis identified distinct clusters in the volatile profiles of the kefirs. Our results suggest that buffalo and ewe milk kefirs may be viable alternatives to cow milk kefir, with potential for consumer acceptance based on sensory properties.

Gülirmak Güler, Kübra; Uzun, Sevda; Emirza, Elif Güzide
Aim: In this study, it was aimed to evaluate the secondary traumatic stress and coping experiences of psychiatric nurses who care for people who have experienced psychological trauma with a phenomenological approach. Materials and Methods: In this study, semi-structured in-depth interviews were conducted with 18 psychiatric nurses residing in Turkey using the phenomenological research method. The criterion sampling method was used to reach the sample group. Interviews continued until data saturation was achieved, and all interviews were audio-recorded and then transcribed. The data were analysed using thematic analysis. The study was conducted and reported using the COREQ checklist. Findings: In the analysis of the data, three themes (difficulties in caring for people who have experienced trauma, the effects of caring for people who have experienced trauma on the individual and coping, reflections of secondary trauma on the profession) and seven sub-themes (mental, physical, social, psychosocial difficulties and coping, quality of care, professional and organisational aspects) were identified. Conclusion: As a result of the study, it was determined that secondary traumatic stress was observed in psychiatric nurses caring for individuals who experienced psychological trauma. It was determined that caring for people who have experienced psychological trauma can negatively affect nurses psychosocially, and individuals have difficulty coping. In line with the results of the study, it is thought that necessary intervention programs should be created for nurses experiencing secondary traumatic stress.

Dinç, Artum
This research examines how collective memory management has influenced the images, symbols, historical artifacts, names, and language of Turkish culture in Iran since 1925 and how Turks for anti-discrimination have responded. This study employed a qualitative research model, with data collected through a relevant literature review and interviews. The sample was selected from Turks who have expressed reactions to the Persianization process. The findings were obtained through open and axial coding of the collected data and an inductive inquiry strategy. The findings revealed that, in line with the assimilation (Persianization) policies implemented in Iran, historiography and memory management practices based on Persian nationalism have been perpetuated against Turkish identity and its collective memory. This process is carried out by erasure, forgetting, amnesia, annulment, obsoletion, abandoning, humiliating, and banning symbolic representations, historical artifacts, names, and the language belonging to Turkish culture. The findings also demonstrated that Turks have not remained passive in the face of these practices but have actively sought to commemorate and preserve their language, names, historical events, artifacts, and heroes through artistic events, ceremonies, sports competitions, new media, legal channels and protests. From the selective coding of the findings, it can be concluded that the management of collective memory based on essentialist, monist, exclusionary and supremacist Persian nationalism are nowadays being questioned and debated in intellectual discussion, political competition and everyday life scenes. It can be concluded that the attitude of the political authority is not towards recognizing ethnonational diversity and their rights in Iran, but towards maintaining uncertainty.
- MakaleAçık Erişim2025Scopus SJRQ1The Effect of Music on Fear and Anxiety of Children During Tomography: A Randomized Controlled Double-Blind Study
Kurudirek, Fatma; Demir Barbak, Zülbiye; Demir İmamoğlu, Zeynep; Çiftci, Kamile; Delice, Orhan
Aim: This study was conducted to determine the effect of a musical intervention during computed tomography (CT) on fear, anxiety and vital signs of children. Method: This randomized, double-blind controlled trial was conducted according to the Consolidated Standards of Reporting Studies (CONSORT) guidelines. The study sample included children aged between 6 and 10 years who met the inclusion criteria and underwent CT scan in the emergency department of a public hospital in eastern Turkey between 18 April and 20 May 2023. The research was completed with a total of 60 children, randomized to one of two groups. The nursing intervention of the study was playing music. Data were collected through face-to-face interviews using the Child and Family Information Form, the Children's Fear Scale (CFS), Children's Anxiety Meter-State (CAM-S) and the Vital Signs Monitoring Form (pulse, blood pressure and oxygen saturation). Ethical principles were followed in the research. Results: The level of fear, anxiety, pulse rate and respiratory rate of the children in the musical intervention group during CT scanning were lower than in the control group (p < 0.05). No difference was found between the groups in terms of oxygen saturation (p < 0.05). Conclusion and Recommendations for Implementation: The results of this study suggest that musical intervention during CT scanning in children is effective in reducing the level of fear and anxiety and stabilizing vital signs. By using such nonpharmacologic methods, nurses can provide support to children and alleviate emotional difficulties during procedures. Trial Registration: NCT06086509. Summary: What is already known about this topic? Music therapy is recognized as an effective nonpharmacologic intervention to reduce fear and anxiety in paediatric patients undergoing medical procedures. Previous studies have shown that musical intervention during CT scans can calm children, potentially reducing the need for sedation and improving compliance. Knowledge gaps remain regarding the specific effects of music on physiological parameters like pulse and respiratory rates during paediatric CT scans. What this paper adds? This study demonstrates that musical intervention during CT scans significantly reduces fear and anxiety levels in children aged 6–10 years. The research findings show that music intervention can also stabilize vital signs, such as pulse and respiratory rates, during CT scans, suggesting a relaxed physiological state. The results support the idea that incorporating music into paediatric imaging procedures can enhance patient comfort and improve the quality of the imaging process by encouraging children to remain still. The implications of this paper: Incorporating music therapy into routine paediatric imaging procedures can reduce anxiety, improve patient cooperation and potentially reduce the need for sedatives. Future research could explore the optimal types of music, volume levels and delivery methods to maximize the calming effects on children during various medical procedures. Training programs for paediatric healthcare providers can include education on the benefits of nonpharmacologic interventions, like music therapy, to reduce anxiety and improve patient outcomes in clinical settings.

AZ31 magnesium alloy is one of the lightweight metallic engineering materials that are widely used in many industrial areas such as aviation, space, automobile and electronics industries, biomedical applications, where structural weight reduction is at the forefront of design principles. This study focuses on the growth of MgO and MgO:B5H10NaO13 doped oxide coatings on the surface of AZ31 magnesium alloy by micro arc oxidation (MAO) method in order to improve its usage areas and lifetime in industrial applications, and to investigate the structural, morphological, adhesion and corrosion properties of the grown coatings. In the study, MgO coatings were grown by MAO method and MgO:B5H10NaO13 doped composite oxide coatings were grown by adding sodium pentaborate (B5H10NaO13) nanoparticles into the electrolytic solution in MAO method. The phase structure of the grown coatings was determined by X-ray Diffraction (XRD), microstructure by Scanning Electron Microscopy (SEM) and chemical composition by Energy Dispersive X-ray Spectroscopy (EDS). The hardness of MgO and MgO:B5H10NaO13 doped composite oxide coatings were determined by microhardness tester, the adhesion resistance with the base material was determined by Scratch Tester and the corrosion resistance was determined by potentiodynamic polarization tester. As a result, it was observed that dense and homogeneous coatings were grown on the surfaces of particle-added (MgO:B5H10NaO13) coatings, that porosity and pore sizes on the surfaces of the coatings were reduced, that microcracks were reduced, and that coatings with high bond strength with the base material were grown. It was also determined that the corrosion resistance of the coatings with particle addition (MgO:B5H10NaO13) was higher than the corrosion resistance of the coatings without particle addition (MgO).

Objective: This study aimed to examine the relationship between the ergonomic conditions of the work environment and the perception of safety climate among internal medicine nurses. Materials and Methods: This descriptive study was conducted between October 30, 2023, and January 30, 2024, with a total of 440 internal medicine nurses in Turkey using the “snowball sampling” method. Data were collected using the “Personal Information Form,” the “Workplace Ergonomics Scale for Nurses,” and the “Safety Climate Scale.”. Results: A statistically significant difference was found in the mean scores of the “Workplace Ergonomics Scale for Nurses” based on marital status, educational level, perceived workload, and whether the nurses had received occupational safety training (p < 0.05). However, no significant difference was observed in the scale scores based on gender, professional experience, or satisfaction with the work environment (p > 0.05). A significant difference was also identified in the mean scores of the “Safety Climate Scale” according to gender, educational level, professional experience, satisfaction with the work environment, and occupational safety training status (p < 0.05). A significant negative correlation was found between the scores of the “Workplace Ergonomics Scale for Nurses” and its subdimensions and the safety training subdimension scores. Data were analyzed using t-test, ANOVA, and correlation analysis. Conclusion: In conclusion, improving ergonomic conditions, strengthening managerial support, establishing effective safety communication, and promoting continuous education are recommended as key strategies to ensure that nurses work in a safe and supportive environment. Additionally, implementing tailored interventions based on demographic and professional characteristics may contribute to the development of a safety culture in nursing and the improvement of patient care quality.

Malik, Ihyani; Karimullah, Suud Sarim; Okur, Hüseyin; Rahman
The ecological crisis reflects the failure of ethical relations between humans, nature, and power structures, thus demanding a review of the paradigm of domination that underlies these relations. This study analyzed how the principles of Islamic law can be integrated with the ideas of ecofeminism to create more inclusive and sustainable environmental policies. The study used an intersectional approach with comprehensive literature analysis and gender analysis frameworks to understand how social identity affects women's participation in ecofeminism and environmental protection based on Islamic law principles. The results of the study state that the integration of the principles of ecofeminism and Islamic law has excellent potential to create fair and sustainable environmental policies based on justice (‘adl), balance (mizan), and responsibility (khalifah). The concept of khalifah affirms the role of humans as custodians of the earth, provides a theological reason to support environmental conservation and inspires collective responsibility, including the role of women as essential agents. Programs that give women access to land and natural resources increase their participation in agriculture and environmental management, reduce poverty, and strengthen their role as agents of change. However, challenges such as resistance from patriarchal communities, lack of financial and technical support, and the need for ongoing education and training must be overcome. Technology also plays a crucial role in supporting inclusive and sustainable environmental policies.

Background: Infertility has become an important public health problem in developing countries due to its high prevalence. Infertility is a difficult crisis situation with psychological and spiritual dimensions. Aims: The aim of this study is to determine whether religion provides support or conflict for the infertility process in women. Methods: This research was designed as a descriptive qualitative study. This study was conducted in a governmental hospital's infertility outpatient clinic in Istanbul, Turkey. Twenty participants participated in the face-to-face, in-depth interview technique used to gather the research data. A semi-structured interview and a comprehensive information form were used to gather data. Results: In line with the interviews with the participants, 2 main themes, 9 sub-themes and 12 codes for the sub-themes were determined as the findings obtained based on the content analysis in the study, positive religious behaviors and negative religious behaviors. Conclusions: In our study, it was found that women felt unhappy, hopeless and helpless and could not accept not being able to have children. Women blamed religion for their infertility. Religion first caused infertile women to experience conflict. After the conflict, women with religious affiliation perceived religious support as a source of conflict for others.

In this study, the effects of 0 wt% (C0), 10 wt% (C1), 20 wt% (C2) and 40 wt% (C3) B4C content on the microstructure, mechanical properties and dry wear properties of Al2024/B4C composites were investigated. In order to prepare Al2024 matrix composites with different B4C particle contents, mechanical milling (MM) and hot pressing (HP) were employed as powder metallurgy methods. It was found that the θ (CuAl2) phase content in the microstructure of Al2024/B4C compact materials increased with increasing B4C particle reinforcement, reaching its highest value at 40 wt% B4C (C3) reinforcement ratio. As the B4C particle reinforcement content increased, the hardness values of the composite samples increased. Flexural strength values were 445.30 MPa, 495.20 MPa, 277.59 MPa, and 129.37 MPa for samples coded C0, C1, C2, and C3, respectively. It was found that the C0 sample without particle reinforcement exhibited more than 10 times the volume loss of the C3 sample with the highest particle reinforcement at 450 m sliding distance. The SEM examination of the friction surfaces of the Al2024/B4C composite samples showed that the worn surfaces were composed of delamination, adhesion and smearing layers.

Kaya, Feridun; Rosell, Javiera; Odacı, Hatice; Vergés, Alvaro; Türkkan, Tuğba
The use of the internet has become an increasingly integral part of individuals’ daily lives, bringing negative consequences such as internet addiction. Understanding the motivations behind internet use is crucial for preventing addiction and developing effective intervention strategies. The objectives of this study are to test the validity and reliability of the Questionnaire of Internet Use Motives (MUI) among Turkish adults and to investigate the predictive effects of socio-demographic variables and internet use motivations on internet addiction. The study was conducted with a sample of 640 adults selected through convenience sampling at two different time points. The majority of participants were women, highly educated, and from a middle socioeconomic background. Data were collected using a socio-demographic questionnaire, the Questionnaire of Internet Use Motives (MUI), and the Internet Addiction Test (IAT). To evaluate the structural validity of the scale, a Confirmatory Factor Analysis (CFA) was performed. Additionally, measurement invariance across genders was examined, and Hierarchical Multiple Linear Regression Analyses were conducted to identify predictors of internet addiction. CFA confirmed the structural validity of the MUI, revealing a five-factor structure with a good fit to the data. The five identified motives were enhancement, coping, social, conformity, and utility. The analyses also demonstrated that the scale possesses convergent and discriminant validity, as well as high reliability. Furthermore, the instrument exhibited measurement invariance across genders. Significant predictors of internet addiction included educational level, socioeconomic status, and the enhancement, social, coping, and conformity motives. The validated MUI provides a robust tool for assessing internet use motives in Turkish adults, offering a foundation for future research and intervention development. Addressing psychological motives such as enhancement, social, coping, and conformity in prevention and treatment strategies may reinforce efforts to mitigate problematic internet use.

Kiymis, Ibrahim; Yuce, Damla Nur
Healthcare workers (HCWs) serve as the cornerstone of health services, which are among the primary needs during disasters. The chaotic environment caused by disasters can lead to mental health disorders in HCWs, similar to those experienced by disaster victims. Experiencing mental health disorders can hinder HCW’s professional approach to intervention. HCWs should not be overlooked for the possibility of experiencing mental health disorders while providing healthcare services during disasters. Therefore, this study aims to examine the impact of psychological resilience and trauma exposure on PTSD, depression, and sleep disorders among HCWs involved in the Kahramanmaraş Earthquakes, which were Turkey’s most devastating earthquakes. In this quantitative research, a survey technique was employed, reaching 642 hCWs involved in the Kahramanmaraş Earthquakes. Structural Equation Modeling (SEM) was used to test the impact of variables on each other. According to the SEM results, trauma exposure in the HCWs had a significant and positive effect on PTSD (β=+0.899, p = 0.000), depression (β=+0.685, p = 0.000), and sleep disorders (β=+0.603, p = 0.000). Psychological resilience had a significant and negative effect on PTSD (β=−0.278, p = 0.004) and depression (β=−0.322, p = 0.008). Surprisingly, psychological resilience had a significant and positive effect on sleep disorders (β=+0.692, p = 0.000). In conclusion, while trauma exposure led to PTSD, depression, and sleep disorders in the HCWs, psychological resilience mitigated PTSD and depression. Unexpectedly, psychological resilience increased sleep disorders. For this reason, it is recommended that future studies investigate in detail the reasons why HCWs experience sleep disorders and examine them in depth.

Civgin, Emre; Yalcin, Numan
In this paper we explored the algebraic and topological underpinnings of non-Newtonian analysis through the framework of a generator function α. We introduced the α-number systems and the associated arithmetic operations, and we established the corresponding algebraic structures, including groups, fields, and vector spaces defined over α-real numbers. On the topological side, we developed the notions of α-metric spaces and α-sequences, thereby extending core concepts of analysis to the non-Newtonian setting. The study culminates with the formulation of star (*) analysis, which provides a systematic mechanism for transitioning between distinct arithmetic systems, together with a rigorous treatment of *-vector spaces and linear operators.

Yavuzdoğan, A.; Tanir Kayıkçı, E.
Rising sea levels pose significant risks to coastal communities and ecosystems. Accurate modeling of sea level changes is crucial for effective environmental management and disaster mitigation. Machine learning methods are emerging as an important asset in improving sea level predictions and understanding the impacts of climate change. Especially, Long Short-Term Memory (LSTM) models have emerged as a powerful tool for sea level anomaly modeling, but there is an increasing need for more advanced models in this area. This study enhances existing methodologies by introducing a novel approach using an LSTM Auto-Encoder model, designed to compress input data into a lower-dimensional latent space before reconstructing it, thereby capturing complex temporal dependencies and anomalies effectively. We compared LSTM Auto-Encoder model performance with that of a Stacked LSTM network, which learns complex temporal patterns through multiple layers, and a traditional damped-persistence statistical model. Our results demonstrate that the LSTM Auto-Encoder model not only outperformed these models in predicting sea level anomalies across various lead times but also exhibited superior generalization capabilities across both satellite altimeter and in-situ data. These findings highlight the potential of the LSTM Auto-Encoder model as a powerful tool in coastal management and climate change studies, underscoring the critical role of advanced machine learning techniques in enhancing our predictive abilities and informing disaster preparedness strategies.

The aim of this study was to investigate the antioxidant, cytotoxic, and antibacterial activities of ethanol extract (SRE) and its hexane (SRH), chloroform (SRC), ethyl acetate (SREA), and aqueous ethanol (SRAE) sub-extracts obtained from the fruits of Scabiosa rotata M. Bieb. Molecular docking studies were also performed to evaluate the interactions of the most active sub-extract with the human mitochondrial ABC transporter (ABCB10) protein, plays an important role in cellular oxidative stress regulation and mitochondrial function. Total phenolic (TPC) and flavonoid (TFC) contents and antioxidant radical scavenging activities (1, 1-diphenyl-2-picryl hydrazyl [DPPH] and 3-ethylbenzothiazoline-6 sulfonic acid [ABTS]) of all extracts were determined. Cytotoxic activity was evaluated on different cell lines, such as HepG2 (liver cancer), MCF-7 (breast cancer), and HeLa (cervical cancer) cells. Antibacterial activity was tested against Escherichia coli, Pseudomonas aeruginosa, Enterococcus faecalis, and Staphylococcus aureus. SREA showed the best antioxidant activity with IC50 values of 54.20 μg/ml and 48.56 μg/ml for DPPH and ABTS, respectively, and also had high TPC (499.06 mg GA/g) and TFC (327.45 mg QE/g). Furthermore, SREA showed significant cytotoxicity comparable to cisplatin with IC50 values of 51.29, 51.41, and 52.89 μg/ml for HepG2, MCF-7, and HeLa cells, respectively. However, none of the extracts showed antibacterial activity. The analysis using liquid chromatography-mass spectrometry (LC/MS-MS) on SREA found that the main phenolic compounds are chlorogenic acid, hesperidin, quinic acid, and isoorientin. Molecular docking of the major compounds showed that chlorogenic acid (2.21 mM) exhibited the strongest binding affinity, followed by hesperidin (5.83 mM), quinic acid (8.86 mM), and isoorientin (13 mM). These findings indicate the potential of SREA to be used as a natural antioxidant and anticancer agent.

Karahan, Selim; Guler, Cengiz
In this study, under laboratory conditions, hazelnut husk and astragalus plant were mixed separately into black pine wood chips, and multi-purpose boards were produced from the obtained chips with urea formaldehyde glue. After the hazelnut husk and astragalus plant were dried and ground, they were added to the chip and glue mixture in certain proportions. Hazelnut husk mixture ratios were applied as 100 %; 0 %, 75 %; 25 %, 50 %; 50 %, 25 %; 75 %, 0 %; 100 % to black pine wood chip in the particle board mixture. These ratios were made in the same way for the astragalus plant. From these mixtures, chipboard blanks of 16 mm thickness and densities between 0,68 g/cm3 and 0,72 g/cm3 were produced. Density, moisture content, thickness increase, water intake, bending strength, modulus of elasticity in bending and tensile strength perpendicular to the surface were tested in physical and mechanical experiments. According to the results obtained, as the participation rate of hazelnut shells and astragalus increased, the durability properties of the panels decreased. At the same time, it shows that the technological properties of the panels produced by adding up to 25 % astragalus plant and hazelnut shells to the mixture comply with the standards.

Ice cream is classified as a dairy product or frozen dessert. Various fruits have been incorporated into ice cream formulations to enhance their quality and nutritional properties. In this study, ice creams were prepared with barberry at four different concentrations (0%, 5%, 10% and 15%). The physicochemical, rheological characteristics, antioxidant activity, mineral content and sensory properties of the samples were examined. With the addition of barberry, the dry matter (DM), acidity and overrun values increased, while pH and fat content decreased. The viscosity and consistency coefficients were highest in the samples containing 10% and 15% barberry. All samples exhibited pseudoplastic flow behavior. The colorimetric parameters showed significant differences among the samples, except for the C* value. The sample with 5% barberry had higher levels of Ca, Na, Mg, S, Fe and Zn compared to the other barberry-added samples. The sample containing 15% barberry demonstrated the highest DPPH scavenging activity (22.15 μg/mL) and total phenolic content (TPC) (1474.04 mg GAE/g), while the sample without barberry had the lowest values (143.19 μg/mL and 149.48 mg GAE/g, respectively). Additionally, the control sample received the lowest scores for gumming structure, texture, melting in the mouth, resistance to melting and overall acceptability. These findings suggest that incorporating 10% barberry could enhance the quality and nutritional value of ice creams.
