- MakaleAçık Erişim2026Scopus SJRQ1Quantifying agricultural resilience under climate variability: a data-driven climate resilience index for European cereal systems
Utku, Anil; Radulescu, Magdalena; Barut, Abdulkadir; Alofaysan, Hind
Climate variability and extreme weather events pose an increasingly serious threat to agricultural productivity in Europe. Although many studies have focused on the mean yield response to climate change, relatively few have attempted to offer a comprehensive, multi-dimensional view of agricultural resilience, separating long-term productivity trends from short-term climate-induced fluctuations. In this paper, a data-driven Climate Resilience Index is proposed to assess the resilience of European cereal systems under climate stress. Annual yield time series are decomposed into trend and anomaly components to identify interannual deviations driven by climate variability. Machine learning and deep learning algorithms, including RF, CatBoost, CNN, LSTM, TCN, and a TCN-LSTM hybrid model, are used to assess the predictive validity of climate extreme indices and persistence patterns. Among the evaluated models, the TCN-LSTM architecture achieved the highest predictive performance with 0.8347 R2, outperforming standalone temporal and ensemble-based models. The PCA-based exposure framework explained 68.4% of the total climate variability within the first principal component, indicating a highly concentrated climate-stress structure. Feature importance analyses further revealed that lagged yield anomalies and rolling volatility indicators were the dominant predictors of resilience dynamics. The findings show that temporal models perform better than traditional ensemble methods, emphasizing the significance of multi-year recovery mechanisms in anomaly evolution. To provide a consistent measure of exposure, principal component analysis is used to reduce correlated climate indicators into a multi-dimensional climate stress index. The CRI captures these three essential elements: climate exposure, yield variability, and recovery. The results at the country level show substantial variability across Europe, indicating that while exposure intensity is important, recovery dynamics are also critical to understanding resilience. The results also show that there are structurally distinct resilience profiles, and robustness tests indicate that country rankings are not sensitive to different weights and recovery functions. The results clearly show that recovery and adaptive capacity are critical to agricultural sustainability amid growing climate uncertainty. The CRI developed in this paper provides a clear, empirically valid framework for comparing resilience in agricultural systems.

İncele - MakaleAçık Erişim2026Scopus SJRQ1Examining the effect of authentic leadership and contextual performance on work engagement among employees working in sports organizations
İnce, Uğur; Özcan, Büşra; Siyahtaş, Anıl; Erdoğan, Ramazan
Background – This study examines the relationship between authentic leadership and employees’ contextual performance and investigates its association with work engagement. Specifically, the aim was to explore how authentic leadership practices are associated with employee motivation and job performance in the sports sector. Methods – The study employed a quantitative research method using measures of authentic leadership, work engagement, and contextual performance. Data were collected through surveys administered to participants, and various statistical analyses were conducted. A mediation analysis was conducted to examine whether work engagement mediates the relationship between authentic leadership and contextual performance. Results – The analysis showed that authentic leadership is positively associated with work engagement (β = 0.516; p < 0.001). Work engagement is also positively associated with contextual performance (β = 0.393; p < 0.001). Mediation analysis suggested that authentic leadership is indirectly associated with contextual performance through work engagement [indirect effect β = 0.205; 95% CI (0.152, 0.259); p < 0.001], while the direct association between authentic leadership and contextual performance remained significant (β = 0.311; p < 0.001). Conclusion – The study’s results indicate that authentic leadership is positively associated with contextual performance via higher employee engagement in the sports sector. The trusting environment and supportive communication provided by authentic leaders are associated with higher employee motivation and linked to better performance outcomes. The findings suggest that sports managers may benefit from cultivating authentic leadership qualities, which are likely to be associated with greater organizational effectiveness.

Yeşiltepe, Akgün; Daşbilek, Ferhat; Ayhan, Mehmet Osman
Background: Health literacy, anxiety, and perception directly affect healthcare students' readiness for professional roles. Assessing these factors is crucial to enhance both their well-being and patient care quality. This study examined health literacy, health anxiety, and health perception among Health Sciences students and their links to socio-demographic factors. Methods: A cross-sectional and descriptive design was used in accordance with the STROBE guidelines. The sample, consisting of 258 students from Munzur University Faculty of Health Sciences, was selected using stratified and simple random sampling methods. Data were collected using a Descriptive Information Form, the Health Literacy Scale, the Health Anxiety Inventory, and the Health Perception Scale. Descriptive statistics, Mann−Whitney U, Kruskal−Wallis tests with Bonferroni correction, and Spearman's correlation analysis were conducted using SPSS 26 and JASP 0.19. Results: Students demonstrated inadequate health literacy (17.75 ± 11.37) and moderate health perception (43.43 ± 6.25); the mean health anxiety score was 18.78 ± 6.14. A weak but statistically significant positive correlation was found between health literacy and health anxiety (r = 0.225, p < 0.05) and between health perception and health anxiety (r = 0.215, p < 0.05); however, no significant correlation was observed between health literacy and health perception (r = 0.090, p > 0.05). Health perception revealed statistically significant differences according to maternal education level, place of residence, and frequency of reading health-related research. Health literacy significantly differed by academic department, year of study, perceived health status, and perceived usefulness of online health information. Health anxiety varied significantly by the presence of chronic illness, chronic illness status, perceived health status, medication use, and alcohol/tobacco consumption. Conclusion: The findings highlight the complex interplay between cognitive (health literacy), emotional (health anxiety), and perceptual (health perception) dimensions of student health. Promoting digital health literacy and providing counselling services may help reduce health anxiety and enhance self-awareness among health sciences students.

Dal, Nursel Alp; Beydağ, Kerime D.; Doğan, Aysel
Effective control of pain after cesarean delivery is essential, as poorly managed postoperative pain is a common complication that can impair maternal recovery and early infant care. This prospective, randomized, single-blind controlled trial, conducted in the postpartum unit of Kocaeli University Hospital, Kocaeli, Türkiye, between March 2021 and June 2022, compared the effect of a single neuro-linguistic programming (NLP) session added to standard postoperative care against standard care alone. Seventy-six consenting women were randomized in equal numbers to the intervention (standard care plus NLP) or control (standard care only) group. The primary outcome was pain intensity, measured with the Visual Analogue Scale (VAS) before and after the intervention period. Mean follow-up pain scores were significantly lower in the intervention group (2.37±1.792) than in the control group (6.68±2.068; p<0.001), while baseline pain scores and maternal demographic and obstetric characteristics did not differ significantly between groups. Adding a single NLP session to standard postoperative care effectively reduced pain after cesarean delivery, supporting its use as a non-pharmacological adjunct in postoperative nursing and midwifery practice. African Journal of Reproductive Health © 2026.; Une prise en charge efficace de la douleur après une césarienne est essentielle, car une douleur postopératoire mal gérée constitue une complication fréquente susceptible de nuire au rétablissement de la mère et aux premiers soins prodigués au nourrisson. Cet essai prospectif, randomisé, contrôlé en simple aveugle, mené dans l’unité post-partum de l’hôpital universitaire de Kocaeli, à Kocaeli, en Turquie, entre mars 2021 et juin 2022, a comparé l’effet d’une seule séance de programmation neurolinguistique (PNL) ajoutée aux soins postopératoires standard à celui des soins standard seuls. Soixante-seize femmes ayant donné leur consentement ont été randomisées en nombre égal dans le groupe d’intervention (soins standard plus PNL) ou dans le groupe témoin (soins standard uniquement). Le critère d’évaluation principal était l’intensité de la douleur, mesurée à l’aide de l’échelle visuelle analogique (EVA) avant et après la période d’intervention. Les scores moyens de douleur observés lors du suivi étaient significativement plus faibles dans le groupe d’intervention (2,37 ± 1,792) que dans le groupe témoin (6,68 ± 2,068 ; p < 0,001), tandis que les scores de douleur initiaux ainsi que les caractéristiques démographiques et obstétricales des mères ne présentaient pas de différence significative entre les groupes. L’ajout d’une seule séance de PNL aux soins postopératoires standard a permis de réduire efficacement la douleur après une césarienne, ce qui plaide en faveur de son utilisation comme complément non pharmacologique dans la pratique infirmière et obstétricale postopératoire.

Atila, Dinçer; Yeşiltepe, Akgün; Çal, Ayşe
Background: Loneliness and social isolation among older adults is a growing concern in many societies, as the aging population continues to increase. The aim of the study is to examine the relationship between loneliness and quality of life in individuals aged 65 and over who apply to primary health care institutions. Methods: This descriptive-correlational study was conducted face-to-face with 216 individuals aged 65 and over. The socio-demographic form and the Loneliness Scale for Elderly and Quality of Life Scale were used as data collection tools in the study. JASP 0.19, SPSS 26 analysis programs were used to perform t test, One Way ANOVA Bonferrroni test, Pearson correlation, and regression analysis. Results: According to Pearson correlation analysis, strong negative relationships were found between quality of life and loneliness in the elderly. As quality of life increased, levels of loneliness, social loneliness, and emotional loneliness decreased (r = −0.854, r = −0.737, r = −0.717; p <0.001). While there was a strong positive relationship between the loneliness scale for elderly and the social loneliness sub-dimension (r = 0.867, p < 0.001), there was also a positive relationship between the loneliness scale for elderly and the emotional loneliness sub-dimension (r = 0.835, p < 0.001). A statistically significant difference was found between chronic disease, educational status, income status, marital status, and both loneliness and quality of life. Conclusion: Loneliness is an important predictor of quality of life among older adults. Both social and emotional loneliness are negatively associated with quality of life, indicating that higher levels of loneliness are linked to lower quality of life in this population.

Ataş, Kübra; Kızmaz, Erhan; Mutlu, Ebru Kaya
Investigating the validity and reliability of the Turkish version of the Breathing Self-Assessment Questionnaire (SEBQ), a tool for measuring dysfunctional breathing. Ninety-two healthy adults (mean (range) age 29.4 (19–56) years; 39 males) were analysed. The SEBQ was translated and adapted into Turkish. At baseline, data were collected using the SEBQ, Nijmegen Questionnaire (NQ), breath-holding time, and Short Form 36 (SF-36). The SEBQ was repeated within 7–14 days. SEBQ validity was assessed through content, structural, and convergent/divergent validity analyses, while reliability was evaluated for internal consistency, stability, and reproducibility. One item was removed based on exploratory factor analysis. The SEBQ has a two-factor structure and explains 50.1% of total variance, confirmed by confirmatory factor analysis. It has a positive correlation with the NQ and a negative correlation with SF-36 subscales, but not with breath-holding time and general health. The Cronbach’s alpha coefficient was 0.931, and the intraclass correlation coefficient was 0.814. The Standard Error of Measurement and Smallest Real Difference were 5.06 and 15.03, respectively. The SEBQ is well-structured, valid, internally consistent, stable, and reproducible for assessing subjective unexplained respiratory symptoms in the Turkish population.

Aglar, Erdal; Ozturk, Burhan; Uyak, Cuneyt; Dogan, Adnan; Tekin, Onur; Durmaz, Orhan; Alan, Davut; Ates, Umut
In the 2023 study, conducted in the Hizan District of Bitlis, aimed at determining the biochemical properties of pistachio trees grafted onto Pistacia khinjuk rootstocks, we identified 11 genotypes. Approximately 500 g of fruit were harvested from each genotype when the green fruit peel color started turning red, for use in the analyses. The various parameters were measured in the harvested fruits, including fruit size, yield, percentage of empty fruits, number of fruits per 100 g, splitting rate, moisture, ash, protein, fat, and mineral content. The fruit analyses revealed significant differences among the genotypes. The largest fruits were found in the G5 genotype, while the smallest were in the G9 genotype. Regarding yield, the highest ratio was observed in the G6 genotype with 46.63%, while the lowest was in the G10 genotype with 13.44%. The splitting rate, which varied by genotype, ranged between 0.97% and 41.88%. No statistical differences were observed in moisture and ash content among the genotypes, but protein content ranged from 18.01% to 28.49%, with the highest protein percentage recorded in the G9 genotype at 28.49%. Nutrient element analysis identified nitrogen (N), magnesium (Mg), calcium (Ca), and potassium (K) in the fruits. K emerged as the most abundant nutrient element across genotypes, followed by CA, magnesium (Mg), and sodium (Na). The G3 genotype exhibited the highest levels of potassium, calcium, magnesium, and manganese. In the fatty acid analyses, 9-octadecenoic acid was found to be the most abundant fatty acid, ranging between 40.5% and 66.7% across genotypes. Additionally, other fatty acids such as hexadecanoic acid, 9,12-octadecadienoic acid, and eicosanoic acid were also detected. These results indicated significant differences in the fatty acid content of the genotypes. As a result the pistachio genotypes examined in this study showed notable differences in terms of fruit yield, quality characteristics, and nutritional values. Particularly, G6 and G9 genotypes stood out with high yield and superior fruit qualities.
- MakaleAçık Erişim2026Scopus SJRQ1Structural alignment and thematic complementarity between ISO 7101:2023 and Türkiye’s hospital quality standards: a qualitative document analysis
Karahüseyinoğlu, Furkan
Background: ISO 7101:2023, adopted in Türkiye as TS ISO 7101:2023, is an international management system standard for healthcare quality management published by the International Organization for Standardization (ISO) in October 2023 and structured according to ISO’s harmonised high-level architecture. SKS Hastane Sürüm 6.1 (Sağlıkta Kalite Standartları Hastane Sürüm 6.1) is Türkiye’s national hospital quality standards framework, comprising 5 dimensions, 46 sections, 523 standards, and 1,599 assessment criteria calibrated to hospital practice. Both documents coexisted within the Turkish health system at the time of this analysis: TS ISO 7101:2023 was adopted by the Turkish Standards Institution (TSE) in November 2023, while SKS Hastane Sürüm 6.1 has been in use since its publication in 2021. Despite the potential relevance of both frameworks to hospital quality governance, to the author’s knowledge, no published study has systematically compared the structural and thematic alignment of ISO 7101:2023 and SKS Hastane Sürüm 6.1. This study aimed to examine the degree and nature of correspondence between ISO 7101:2023 and SKS Hastane Sürüm 6.1 across a comprehensive set of hospital quality management domains. Methods: A qualitative document analysis with structured comparative mapping was conducted using the primary texts of ISO 7101:2023 (accessed as TS ISO 7101:2023) and SKS Hastane Sürüm 6.1. Fourteen analytical dimensions were specified a priori, covering organisational context, leadership and governance, quality planning, patient/person-centred care, patient safety and risk management, workforce competence, clinical and service delivery processes, information management, resource and infrastructure management, external provider management, performance measurement, incident reporting and learning, continuous improvement, and accessibility and equity. A seven-category coding scheme was applied to each dimension: Full Convergence (FC), Partial Convergence (PC), ISO-Dominant Management System Emphasis (ISO-D), SKS-Dominant Operational Specificity (SKS-D), Complementarity (COMP), Limited Explicit Correspondence (LEC), and No Direct Correspondence (NDC). Coding categories are analytical, not evaluative. Standard-level verification extending to confirmed standard codes and assessment-criteria-level content was conducted for five dimensions (D2, D3, D5, D8, D11). ISO 7101:2023 text is paraphrased with clause references; the document is copyrighted and is not extensively quoted. Results: Thirteen of the fourteen analytical dimensions were classified as Partial Convergence (PC). Dimension 7 (Clinical and Service Delivery Processes) was classified as Complementarity (COMP). No dimension was classified as Full Convergence or No Direct Correspondence. The Partial Convergence pattern reflects shared quality management intent across all domains, accompanied by systematic differences in documentary logic, prescriptive specificity, and regulatory mechanism. ISO 7101:2023 addresses quality domains through normative “shall” obligations within a harmonised management system architecture, leaving implementation methods to the organisation. SKS Hastane Sürüm 6.1 addresses the same domains through prescriptive, surveyable hospital standards and assessment criteria. Standard-level verification confirmed operationally specific requirements in SKS across governance committee structures (KKY06-10), risk management (KRY01-05), patient safety (KKY07), information system security and backup (DBY05, DBY10, DBY13), indicator management (GGİ01–07), and national performance reporting. Several ISO constructs — including formal change management planning (Cl. 6.3), risk awareness culture monitoring (Cl. 6.1.2), structured internal audit with independence criteria (Cl. 9.2), and eleven-input management review (Cl. 9.3) — were not confirmed as single equivalent standards in the verified SKS sections. Conclusions: ISO 7101:2023 and SKS Hastane Sürüm 6.1 show broad thematic overlap across hospital quality domains. SKS Hastane Sürüm 6.1 provides an operationally specific, nationally calibrated quality infrastructure for hospitals in Türkiye. ISO 7101:2023 provides a complementary management-system architecture that may supplement SKS’s operational standards with structural constructs for leadership accountability, quality objective documentation, change management planning, and cyclical system evaluation. The two frameworks are better characterised as potentially complementary than as competing. These findings are based on document-level analysis and cannot be interpreted as evidence of implementation effectiveness. Empirical research is needed to assess how the frameworks interact in hospital practice and to determine what benefits, if any, alignment may offer for hospital quality governance in Türkiye.

Karatay, Gülnaz
This study examines the construction of collective mourning and social memory in digital environments following the discovery of university student Ayşe Tokyaz’s body in a suitcase, using a netnographic approach. Femicide is framed as a form of structural violence that produces societal trauma. A total of 414 online comments from Haberler.com were reviewed; 226 met the inclusion criteria, and 205 were analyzed after data cleaning. An integrated qualitative method combining thematic analysis, manual sentiment coding, and discourse analysis was employed. Findings highlight strong demands for justice and capital punishment, alongside distrust in the legal system and calls for retribution. Patriarchal norms appear in victim-blaming and sexist discourse, while demands to reveal the perpetrator’s identity reflect “digital justice.” Collective mourning is expressed through empathy and shared grief, whereas fear signals ongoing trauma. Some users invoke religious references. As a single-case study, findings are context-specific.

Arslan Topal, E Işıl; Topal, Murat; Çelik, Erdal; Öbek, Erdal
BACKGROUND: The present study investigated the potential health risks of heavy metals (HMs) in the fruits and leaves of mulberry and sour cherry trees exposed to water from Sivas geothermal basin (Turkey). RESULTS: The target HMs were ranked according to their hazard index as: Cd < Pb < Zn < Cu < Ni < Mn < Cr. The total hazard index for mulberry and sour cherry fruits was calculated as 7.87 and 4.57, respectively, and was determined to be well above the safe threshold value of 1.0. At the same time, the calculated cancer risk values exceeded the established maximum limit (1.0 × 10−4) for Ni (6.4 × 10−3) in mulberry fruit and for Cr (1.15 × 10−3) in sour cherry fruit. Ingestion has been identified as the primary route of exposure. The study results showed that Cr and Ni metals were ranked in the order of mulberry fruit > sour cherry fruit > mulberry leaf > sour cherry leaf, and that for mulberry and sour cherry fruit. CONCLUSION: The findings indicate that edible foods exposed to geothermal waters may have adverse effects on human health. Furthermore, the study highlights the necessity of reducing water discharges from geothermal fields and implementing phytoremediation strategies to ensure food safety in geothermally active agricultural basins.

Rapid genetic selection for growth rate and slaughter weight in broilers has been associated with a higher incidence of skeletal disorders, particularly tibial dyschondroplasia (TD), which causes considerable economic losses in poultry production. We investigated the effects of boric acid (BA) and sodium pentaborate pentahydrate (SPP) on growth performance, bone mineralization, tibial histopathology, and osteogenic protein expression in broilers with manganese (Mn) deficiency-induced TD. A total of 360 Ross 308 broiler chicks were used in a 2 × 2 × 3 factorial design with TD status (normal or Mn deficiency–induced TD), boron source (BA or SPP), and supplemental boron level (0, 4.37, and 8.74 mg elemental B/kg diet). Birds were randomly allocated to 12 groups with six replicates of five birds each. Clinical and histopathological findings confirmed TD induction. TD decreased body weight, feed intake, and carcass weight, while increasing feed conversion ratio (p < 0.05). Boron supplementation improved tibial mineral density and content in a dose-dependent manner (p < 0.05). In TD broilers, serum osteocalcin (OCN) concentrations were higher with high-level SPP supplementation than with BA supplementation (p = 0.012). Boron source and level significantly affected serum and bone boron concentrations, bone calcium concentrations (p < 0.05). In TD broilers, tibial osteoprotegerin levels were markedly elevated in the high-level SPP group (p < 0.001), whereas SRY-box transcription factor 9, hypoxia-inducible factor-1α, and tumor necrosis factor-α were reduced (p < 0.05). These findings indicate that SPP exerts regulatory effects on bone metabolism and osteogenic signaling pathways in TD-affected broilers.

Tizar, Ercan; Erdoğan, Ramazan
Background: Powerlifting-based resistance training is increasingly incorporated into athletic conditioning programs; however, its short-term endocrine and metabolic responses remain insufficiently explored. Therefore, this study aimed to examine the short-term, exercise-induced changes associated with a powerlifting-based training program on selected hormonal, metabolic, and lipid profile parameters in male basketball players. Methods: This randomized controlled experimental study was conducted in accordance with CONSORT guidelines. Thirty male basketball players aged 18–24 years were randomly assigned to an exercise group (EG; n = 15) or a control group (CG; n = 15). Both groups continued their routine basketball training three days per week for six weeks, while the EG additionally performed a powerlifting-based training program. Serum concentrations of thyroid hormones (TSH, T3, and T4), insulin, glucose, growth hormone, testosterone, and lipid profile parameters were assessed before and after the intervention. Data were analyzed using two-way repeated-measures analysis of variance to evaluate group × time interactions. Results: Significant group × time interactions were observed for several biochemical parameters (p < 0.05). In the exercise group, insulin levels increased by 53.31%, while pre-exercise glucose levels under standardized conditions decreased by 14.46%. Thyroid hormones (TSH, T3, T4) increased by 45.26%, 18.85%, and 18.25%, respectively. Growth hormone and testosterone levels increased by 28.49% and 18.22%, respectively. In contrast, total cholesterol, LDL cholesterol, and triglyceride levels decreased by 2.49%, 4.28%, and 3.76%, respectively, while HDL cholesterol increased by 5.63%. No significant changes were observed in the control group. Effect size analyses indicated large interaction effects for key variables (e.g., insulin ηp² = 0.749; glucose ηp² = 0.757). The concurrent increase in insulin and decrease in glucose may reflect transient alterations in glucose–insulin dynamics rather than a direct improvement in insulin sensitivity. Conclusion: The inclusion of a powerlifting-based training program was associated with favorable short-term, exercise-induced changes in selected hormonal, metabolic, and lipid profile parameters in male basketball players. However, these findings should be interpreted with caution due to the limited sample size and intervention duration. Further studies employing larger cohorts and longer training periods are warranted to confirm these observations and to clarify their long-term physiological implications. Trial registration: ClinicalTrials.gov (NCT07398248), registered on 29/12/2025.

Macit, Arife; Köktürk, Mine; Serdar, Osman; Alak, Gonca
This research was designed to identify the levels of microplastics (MP) and phthalate esters (PAE) in canned and frozen packaged fish and to assess the human health risks associated with these pollutants. Analyses were carried out on a total of 25 sample groups, including 10 different canned tuna samples, 9 different packaged seafood products, and 6 different packaging materials. Microplastics were characterized and polymer identification was performed using μ-Raman and ATR-FTIR spectroscopy, while PAEs were determined by GC–MS/MS. The obtained data were used to calculate estimated daily intake (EDI), hazard index (HI), hazard quotient (HQ), and cancer risk (CR), and uncertainty was assessed using Monte Carlo simulation. The findings revealed that both microplastic and phthalate exposure were higher in the frozen fish group than in canned products. The highest MP concentrations were recorded in packaged Whiting B (0.73 ± 0.25 items/g) and oil-added canned tuna (0.57 ± 0.15 items/g). Regarding PAEs, while DEHP and DBP were generally prominent, significant peak concentrations of BBP and DNOP were also identified, reaching 1.91 ± 0.01 ppm for BBP in canned tuna with sunflower oil and 1.84 ± 0.01 ppm in packaged whiting. Furthermore, higher exposure was observed in males for most PAEs. HQ and HI values were below 1 (maximum HI: 1.57 × 10−2 for males consuming frozen seafood), while CR values remained within an acceptable range (4.74 × 10−7 to 3.49 × 10−6). In conclusion, health risks related to processed fish consumption appear generally low; however, processing and packaging may contribute to contamination and warrant further investigation.

This study explores the phytochemical composition and antimicrobial potential of Palustriella commutata, Philonotis calcarea, Cinclidotus riparius, Rhynchostegium riparioides, Plagiomnium ellipticum, and Porella platyphylla, with a focus on bryophyte species phenolic constituents and biological activities. HPLC analysis identified seven phenolic acids (4-hydroxybenzoic acid, 2,5-dihydroxybenzoic acid, 3,4-dihydroxybenzoic acid, caffeic acid, vanillic acid, syringic acid, and p-coumaric acid) across all species in varying concentrations. In in vitro antimicrobial tests, the bryophyte extracts used showed significant activity against Pseudomonas aeruginosa (ATCC 9027), while exhibiting relatively lower inhibition against Staphylococcus aureus (ATCC 25923). The study showed that all species extracts exhibited comparable activity to erythromycin against P. aeruginosa, while Cinclidotus riparius and Plagiomnium ellipticum extracts showed no activity against S. aureus, and the remaining species exhibited lower activity compared to erythromycin. Molecular docking studies demonstrated strong binding affinities of these phenolics to the active site of the target macromolecule (PDB ID: 3FRQ), suggesting meaningful interactions with residues such as ARG122 and ASN123, similar to erythromycin binding patterns. The findings indicate that bryophyte-derived phenolic compounds possess significant antimicrobial potential and may serve as promising candidates for the development of novel bioactive agents. This study provides a broad framework for the insufficiently researched antimicrobial potential of bryophytes by establishing direct links between species-specific phenolic fingerprints, experimentally observed antibacterial activities, and predicted receptor-level interactions. Further complementary biological studies are needed to confirm and expand upon these results.

The present study aimed to evaluate the influence of extraction parameters, including solvent concentration, extraction time, temperature, and solid-to-liquid ratio, on total phenolics, total flavonoids, antioxidant DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid), FRAP (ferric reducing antioxidant power), and CUPRAC (cupric reducing antioxidant capacity)), and enzyme inhibitory properties (α-amylase and tyrosinase). Furthermore, an Artificial Neural Network (ANN) model was applied to optimize the extraction conditions. The results demonstrated that extraction conditions significantly affect both chemical composition and biological activity. The optimal conditions (70% ethanol, 30 min, 45 °C, (1 : 30)) yielded extracts with high total phenolic (109.15 mg GAE per g), and total flavonoid content (70.74 mg RE per g), strong antioxidant activity (DPPH: 473.57 mg TE per g, ABTS: 537.58 mg TE per g, CUPRAC: 407.11 mg TE per g, FRAP: 393.91 mg TE per g) and notable enzyme inhibitory potential (0.53 mmol ACAE per g against α-amylase and 75.00 mg KAE per g against tyrosinase). The ANN model showed excellent predictive performance, confirming its suitability for modeling and optimization of complex extraction systems. The present study provides comprehensive insights into optimized ultrasound-assisted extraction methods for the recovery of maximum bioactive compounds and biological activities (antioxidant and enzyme inhibition effect) from C. monogyna flowering branches using experimental design and ANN model. These findings provide a reliable basis for the development of functional and pharmaceutical products. This journal is

Ozdemir, Umit; Mete, Suleyman; Gul, Muhammet
Effective volunteer management requires ensuring operational continuity and maximizing benefits from all team members. Prioritizing volunteers with adequate knowledge and experience in task assignments is crucial for maintaining workflow continuity. This study employs a two-stage model for allocating areas and tasks to volunteers in search and rescue operations. The first stage identifies the optimal number of volunteer response centers using the P-median problem. Considering population density as demand, 7 out of 14 accessible and protected disaster collection areas meeting basic needs are selected as optimal response centers based on distance. In the second stage, a mixed-integer programming model is proposed for volunteer assignment, which prioritizes assigning the most knowledgeable and experienced volunteers to critical positions. The model’s flexibility and applicability are demonstrated by incorporating voluntary rest periods, which are allocated based on the urgent needs of response centers in various post-disaster scenarios. Solved using GAMS/CPLEX, the model’s results show that expert volunteers in low-demand scenarios are prioritized, working 5 out of 9 shifts, while other volunteers receive insufficient assignments. In high-demand scenarios, some response centers face volunteer shortages, with a deficit of 62 volunteers across 9 shifts in non-emergency areas. The study evaluates the benefits and drawbacks of the volunteer assignment model and offers recommendations for future research.

This study examined the adverse effects of sublethal concentrations of cadmium (Cd) and the potential of curcumin (CUR) to mitigate Cd-induced toxicity. We administered 1.5 and 3 mg/L of Cd and 100 mg/kg of CUR to fish (Cyprinus carpio) separately and in combination over 14 days. At the end of the experiments, various haematological and immunological parameters, oxidative stress levels and antioxidant parameters of fish were measured, and the differences between the groups were evaluated. Simultaneous CUR treatment with Cd reversed the changes in haematological parameters in fish, increased immune responses, reduced oxidative stress and normalized the impaired antioxidant enzyme activities. In summary, our study showed that dietary supplementation with CUR may be an effective strategy to reduce the toxic effects of Cd in carp.

Rosehip (Rosa canina L.) is an important wild fruit species valued for its high nutritional and functional properties, particularly its richness in vitamin C, phenolic compounds, and antioxidant activity. Despite the widespread natural distribution of rosehip in Türkiye, many local genetic resources remain insufficiently characterized, limiting their effective utilization in breeding, conservation, and cultivation programs. The present study was conducted to evaluate the morphological, pomological, and biochemical characteristics of naturally growing rosehip genotypes in the Central District of Tunceli and to identify superior genotypes with potential for future breeding and cultivation efforts. Ten rosehip genotypes collected from natural populations at altitudes ranging from 1178 to 1256 m were evaluated for fruit and seed characteristics, fruit color, soluble solids content, titratable acidity, vitamin C, phenolic compounds, flavonoids, anthocyanins, antioxidant activity, and organic acid composition. Significant differences were observed among genotypes for all examined traits. Fruit weight ranged from 1.00 to 1.81 g, soluble solids content from 45.40% to 51.90%, titratable acidity from 1.03% to 2.77%, and vitamin C content from 235.67 to 1126.30 mg/100 g. Total phenolic content, total flavonoid content, total monomeric anthocyanin content, FRAP, and DPPH antioxidant activity values also varied significantly among genotypes. Organic acid analysis revealed considerable variation, particularly in citric and malic acid contents. Principal component analysis explained 92.4% of the total variation and grouped the genotypes into two major clusters. Based on the overall evaluation, genotypes TK2, TK5, TK9, and TK10 exhibited superior performance for several desirable traits. The results demonstrate the substantial genetic diversity present in the natural rosehip populations of Tunceli and highlight their potential value for germplasm conservation, selection breeding, and sustainable cultivation programs.

Solmaz, Adnan; Çakmak, Reşit; Kaya, İsmet
Schiff base derivatives, namely 3-(((2-hydroxynaphthalen-1-yl)methylene)amino)-1-phenyl-1-pyrazole-5-one (3-APPHNA) and 4-(((2-hydroxynaphthalen-1-yl)methylene)amino)-1,5-dimethyl-2-phenyl-1H-pyrazol-3-one (4-APPHNA), were synthesized via the condensation reaction of 3-amino-1-phenyl-2-pyrazolin-5-one (3-APP) and 4-amino-2,3-dimethyl-1-phenyl-3-pyrazolin-5-one, (4-APP) with 2-hydroxynaphthaldehyde (2-HNA) in ethanol. Synthesized monomers were then converted into their oligomeric derivatives via oxidative polycondensation carried out using NaOCl. The structural, thermal, optical, electrochemical, and morphological properties of the obtained monomers were comprehensively characterized using fourier transform infrared (FT-IR), proton nuclear magnetic resonance (1H-NMR), carbon-13 nuclear magnetic resonance (13C-NMR), ultraviolet-visible spectrophotometer (UV–vis), thermogravimetry-derivative thermogravimetry (TG-DTG), and cyclic voltammetric analyses. Spectroscopic studies confirmed the successful synthesis of Schiff bases and the presence of stable azomethine bonds. Molecular weight, glass transition temperature, and surface morphologies of oligomers were determined by gel permeation chromatography (GPC), differential scanning calorimetry (DSC), and field emission scanning electron microscope (FE-SEM) measurements, respectively. The Mn values of oligo(3-APPHNA) and oligo(4-APPHNA) were found to be 3400 and 2900 Da, respectively. The results revealed an oxidative oligomerization process yielding relatively narrow molecular weight distributions. Oligo(4-APPHNA) has shown more pronounced semiconductor properties compared to other oligomers, considering its 2.30 eV optical band gap and frequency-dependent electrical behavior. Additionally, dielectric measurements showed that oligo(4-APPHNA) exhibited higher dielectric constant, dielectric loss, and AC conductivity values throughout the investigated frequency range. These findings suggest that the synthesized oligomers are promising candidate materials for future optoelectronic and semiconductor applications, but further research at the device level is needed.

Natural disasters not only cause physical destruction but also lead to various psychological problems affecting the mental health of individuals. This study was conducted to determine the levels of post-earthquake trauma in athletes who experienced earthquakes and whether certain variables made a difference in this situation. The sample of the study consisted of 359 athletes living in 11 provinces affected by the earthquakes centered in Kahramanmaraş, Turkey, on February 6, 2023. Participants were reached using the Snowball Sampling Method. The Sociodemographic Information Form and the Post-Earthquake Trauma Level Determination Scale were used to collect data. As a result of the descriptive statistics, it was seen that athletes experienced above-average earthquake trauma (M = 65.84). When examined in terms of sociodemographic variables, it was found that women showed more symptoms of earthquake trauma than men, those who experienced the loss of relatives showed more symptoms than those who did not, and those who experienced the loss of a home showed more symptoms than those who did not. In conclusion, while exercise and physical activity are methods used to cope with trauma, being an athlete alone is not sufficient to cope with earthquake trauma. Women, whether athletes or not, experience more earthquake trauma than men. Losing relatives exacerbates the trauma caused by the earthquake. Furthermore, the loss of a home, which prevents individuals from meeting some basic physiological needs, is a significant factor in earthquake trauma.
