Çelikel, Baha Engin; Yılmaz, Coşkun; Demir, Alper; Sezer, Süreyya Yonca; Ceylan, Levent; Ceylan, Tülay; Tan, Çetin
Background: The effect of inspiratory muscle training on upper limbs One Rep Maximum (1RM) in professional natural bodybuilders is still unclear. Our aim of this study is to investigate the effects of a 6 weeks inspiratory muscle training on 1RM results. Methods: This study included 14 athletes, that had participated in international bodybuilding competitions. Each athlete had been training for minimum of 5 years and at least 5 h per week. The participants were randomly divided into two groups: inspiratory muscle training (IMT) and control (CON) groups. The IMT group and CON group consisted of seven subjects. While the control group continued with the normal training regime, the IMT group additionally performed inspiratory muscle training with the resistance setting of the PowerBreathe® Classic device set to 40% of the participant’s MIP. Prior to and during the 6-week training period, the bench press 1 RM, anthropometry, pulmonary function tests, and maximal inspiratory (MIP) and expiratory (MEP) pressure measurements were obtained. A nutrition protocol developed by a qualified dietician was implemented for each athlete. Results: The mean maximal strength of the respiratory muscle training group changed by 14.39%, whereas that of the control group changed by 9.43% (p = 0.012). The changes in the mean FVC (p = 0.000), FEV1 (p = 0.001), PEF (p = 0.064), MIP (p = 0.001), and maximal expiratory pressure (p = 0.017) were greater in the IMT group. The mean circumferences of the shoulder (p = 0.004), chest (p = 0.008), arm (p = 0.004), and neck (p = 0.003) improved more in the IMT group than in the CON group. A reduction in abdominal measurement was observed in the IMT group (p = 0.039), whereas no notable discrepancy was identified in body fat percentage (p = 0.295). Conclusion: In conclusion we identified that the addition of progressive loading inspiratory muscle training for competition preparation programs in professional natural bodybuilders will further improve their respiratory function, respiratory muscle strength, maximal strength, and muscle development. This research provides valuable insights into how IMT influences bodybuilding training outcomes, potentially guiding future interventions and program designs to better support strength development and body composition in bodybuilding training contexts.

Background: Climate change is one of the most significant issues of today. This study aims to investigate climate change awareness, anxiety, and hope levels among university students who participate in activities at youth offices and examine the relationship between them. Methods: The study population consisted of student members who were actively engaged in Youth Offices located within four public universities in the Eastern Anatolia Region of Türkiye. The study sample includes 881 volunteer participants, consisting of 345 (39.2%) male and 536 (60.8%) female students. The data were analyzed employing IBM SPSS 25. Statistical analyses included the independent samples t-test, one-way ANOVA, Tukey’s post-hoc test, and Pearson’s correlation coefficient. Results: The results indicate that university students have moderate levels of climate change awareness, anxiety, and hope. A positive correlation was observed, wherein higher awareness levels were associated with increased anxiety and hope. Male students demonstrated higher awareness and anxiety levels than female students. Among participants, students from 1. University exhibited the highest levels of climate change awareness, anxiety, and hope. Additionally, graduate students and individuals living in rural areas showed higher awareness and anxiety levels, whereas individuals with better economic conditions exhibited lower anxiety and hope levels. Conclusion: Given these results, it is recommended that universities develop and implement educational programs to enhance climate change awareness and extend these initiatives across campuses.

Background: The extant research on judo sports has principally concentrated on the physiological effects of training. Conversely, there has been limited attention paid to studies on psychological resilience, self-control, and emotional expression levels. The present study examined the effects of Judo exercises on psychological resilience, self-control, and emotional expression levels in healthy male subjects. Methods: The present study comprised 50 healthy, sedentary male subjects. The subjects were randomly divided into two groups: one group participated in judo training (JT) and the other group served as the control group (CON). The sample sizes for the JT and CON groups were both 25. The JT group underwent judo training, while the CON group maintained their usual lifestyle. The Brief Psychological Resilience Scale, the Multidimensional Brief Self-Control Scale, and the Berkeley Emotion Expression Scale were administered prior to and following the 6-week training period. Results: The study demonstrated that a 6-week judo training regimen exerted a significant effect on the psychological resilience score (e.s. = 1.047, p < 0.001), while no such effect was observed in the Control group (e.s. = 0.0091, p = 0.751). In the context of self-control levels, an effect was observed on the Initiation sub-dimension (e.s. = 1, 739, p < 0.001), yet no effect was found on the Inhibition dimension (e.s. = 0.052, p = 0.892). In the control group, a significant decrease was identified in the Initiation sub-dimension (e.s. = 0, 785, p = 0.001) and Inhibition sub-dimension (e.s. = 1, 861, p < 0.001). The findings indicate that impulse power (e.s. = 0.395) and concealment (e.s. = 0.428) exerted a negligible influence on the emotional expression sub-dimensions. Conversely, psychological resilience (e.s. = 0.886) demonstrated a substantial impact. Conclusions: The judo exercises demonstrated a favorable impact on psychological resilience, self-control, and emotional expression levels in healthy male subjects. The findings of this study may offer significant insights into the impact of judo exercises on psychological resilience, self-control, and emotion expression levels. These findings could serve as a guide for the development of future interventions and program design in the domain of sport psychology.

Background: The present study set out to ascertain the effects of combined exercises, consisting of resistance training and plyometric exercises at varying degrees of intensity, on biochemical and respiratory parameters in female volleyball players. Methods: The research group consisted of 20 professional female volleyball players who participated in national and international volleyball competitions. Participants were randomly divided into two groups: a control group (n = 10) that performed low-intensity exercises at 30%–50% intensity, and an experimental group (n = 10) that followed a high-intensity exercise programme at 60%–80% intensity. Blood samples and spirometric respiratory function values were collected before and after the 8-week exercise program. The biochemical analyses included the assessment of luteinizing hormone (LH), growth hormone (GH), insulin-like growth factor-1 (IGF-1), and total iron binding capacity. Respiratory function was analysed using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and forced expiratory flow at mid-expiration (FEF). The data were analysed using the SPSS statistical package. Results: The results demonstrated a decline in IGF-1, GH, and total iron-binding capacity levels, and an increase in LH levels, in the biochemical parameters of the control group. Additionally, FVC, FEV1, and FEF values exhibited an increase in the control group. Conversely, the experimental group demonstrated a significant increase in LH, GH, IGF-1, and total iron-binding capacity levels. With regard to respiratory parameters, an increase in FEF values was observed, whilst FVC and FEV1 values decreased. The present findings suggest that high-intensity plyometric resistance exercises have more pronounced effects on biochemical responses, but may trigger different adaptation mechanisms in respiratory capacit. The results of the study showed that there was a difference between the control group’s GH, IGF-1, FVC, and FEV1 data and the experimental group’s GH, IGF-1, FVC, and FEV1 data. Conclusions: In conclusion, plyometric resistance exercises at varying intensities influence both respiratory and biochemical parameters in female volleyball players. Accordingly, well-planned and individualised plyometric resistance training programmes are thought to enhance both the health and athletic performance of athletes.

Swami, Viren; Stieger, Stefan; Voracek, Martin; Aavik, Toivo; Ranjbar, Hamed Abdollahpour; Adebayo, Sulaiman Olanrewaju; Afhami, Reza; Ahmed, Oli; Aimé, Annie; Akel, Marwan
The Satisfaction With Life Scale (SWLS) is a widely used self-report measure of subjective well-being, but studies of its measurement invariance across a large number of nations remain limited. Here, we utilised the Body Image in Nature (BINS) dataset–with data collected between 2020 and 2022 –to assess measurement invariance of the SWLS across 65 nations, 40 languages, gender identities, and age groups (N = 56,968). All participants completed the SWLS under largely uniform conditions. Multi-group confirmatory factor analysis indicated that configural and metric invariance was upheld across all nations, languages, gender identities, and age groups, suggesting that the unidimensional SWLS model has universal applicability. Full scalar invariance was achieved across gender identities and age groups. Based on alignment optimisation methods, partial scalar invariance was achieved across all but three national groups and across all languages represented in the BINS. There were large differences in latent SWLS means across nations and languages, but negligible-to-small differences across gender identities and age groups. Across nations, greater life satisfaction was significantly associated with greater financial security and being in a committed relationship or married. The results of this study suggest that the SWLS largely assesses a common unidimensional construct of life satisfaction irrespective of respondent characteristics (i.e., national group, gender identities, and age group) or survey presentation (i.e., survey language). This has important implications for the assessment of life satisfaction across nations and provides information that will be useful for practitioners aiming to promote subjective well-being internationally.

Introduction and Objective. Menstrual poverty lies at the intersection of poverty, sustainability, reproductive rights, and gender inequality. The study investigates menstrual poverty among women affected by the 2023 earthquake in Turkey. Materials and Method. A descriptive cross-sectional study was conducted between 24 April – 24 May 2023 with 400 women impacted by the earthquake. Data were collected via social media using a survey form. Chi-square tests, Bonferroni test, and binary logistic regression model were used for statistical analysis. Results. The mean age of participants was 27.27 ± 8.40 years; 69.5% had higher education, 57.0% lived in urban areas, and 90.5% had no chronic disease. A significant relationship was found between access to menstrual products and basic needs (clean water, toilet paper, soap, safe toilet access, and healthcare) during menstruation after the earthquake (p<0.05). A significant correlation was also observed between disruptions to the menstrual cycle and the following variables: lack of privacy, perception that lack of privacy affected menstruation, healthcare access, and difficulty obtaining menstrual products (p<0.05). Conclusions. Most participants faced difficulties accessing menstrual products, water, hygiene supplies, privacy, and healthcare. Those living in tents or containers reported greater challenges. These barriers contributed to menstrual poverty and impacted women’s cycles. As menstrual health and hygiene are basic needs and human rights, menstrual poverty must be addressed globally.

Phlomis species (family Lamiaceae) are highly valued as food and herbal medicine. The present study is designed to investigate the chemical composition and antioxidant and enzyme inhibitory activities of extracts from P. fruticosa, P. herba-venti, and P. kurdica aerial parts. Different classes of metabolites, including phenolic acids, phenylethanoids, flavonoids, iridoids, organic acids, terpenes, and fatty acids, are identified in the three species, with methanol as the best solvent to recover bioactive compounds from the three species in addition to ethyl acetate for P. kurdica. Around 70% methanol extract of P. herba-venti exerts the best radical scavenging and ions-reducing properties, while its methanol extract exhibits the highest acetylcholinesterase inhibitory activity. The ethyl acetate extract of P. fruticosa displays the best chelating power, and its other polar extracts have the highest total antioxidant activity. Furthermore, molecular docking and molecular dynamics simulations have underscored the therapeutic potential of bioactive compounds, including isoverbascoside, samioside, forsythoside B, and hattushoside. In conclusion, the study indicates that these three Phlomis species are a rich source of bioactive molecules with possible therapeutic applications, and the selection of appropriate extraction solvents is crucial for the targeted biological activity.

Purpose: This study investigates not only the impact of first aid training but also how the Teach-Back method influences teachers’ overall epilepsy knowledge, attitudes toward epilepsy, and self-efficacy in managing epileptic seizures. Methods: A total of 166 preschool teachers who filled out the questionnaire form and gave their consent were included in the study between April and June 2022. A quasiexperimental single-group pre-test post-test design was used in the study, Data were collected using the questionnaire form, Epilepsy Knowledge Scale, Childhood Epilepsy Attitude Scale and General Self-Efficacy Scale. The research data were collected by the researchers through face-to-face interviews. Results: It was determined that the rate of correct answers given by preschool teachers to most questions about first aid practices in epileptic seizures increased significantly after the training (p < 0.05). There was a significant improvement in preschool teachers’ first aid practices at the end of the training compared to before the training. The mean score of the Epilepsy Knowledge Scale before the training was 11.16 ± 4.04, after the training was 14.59 ± 2.08, and the difference was statistically significant (p < 0.001). The mean Childhood Epilepsy Attitude Scale score before the training was 47.90 ± 4.02, after the training was 51.53 ± 4.55, and the difference was statistically significant (p < 0.001). Conclusion: Epilepsy education significantly improved teachers’ knowledge and attitudes towards childhood epilepsy. However, the increase in general self-efficacy remained limited. This situation reveals the necessity of practical and long-term programs in addition to theoretical education.

Background/Objectives: The integration of digital imaging technologies in dentistry has revolutionized diagnostic and treatment practices, with panoramic radiographs playing a crucial role in detecting impacted teeth. Manual interpretation of these images is time consuming and error prone, highlighting the need for automated, accurate solutions. This study proposes an artificial intelligence (AI)-based model for detecting impacted teeth in panoramic radiographs, aiming to enhance accuracy and reliability. Methods: The proposed model combines YOLO (You Only Look Once) and RT-DETR (Real-Time Detection Transformer) models to leverage their strengths in real-time object detection and learning long-range dependencies, respectively. The integration is further optimized with the Weighted Boxes Fusion (WBF) algorithm, where WBF parameters are tuned using Bayesian optimization. A dataset of 407 labeled panoramic radiographs was used to evaluate the model’s performance. Results: The model achieved a mean average precision (mAP) of 98.3% and an F1 score of 96%, significantly outperforming individual models and other combinations. The results were expressed through key performance metrics, such as mAP and F1 scores, which highlight the model’s balance between precision and recall. Visual and numerical analyses demonstrated superior performance, with enhanced sensitivity and minimized false positive rates. Conclusions: This study presents a scalable and reliable AI-based solution for detecting impacted teeth in panoramic radiographs, offering substantial improvements in diagnostic accuracy and efficiency. The proposed model has potential for widespread application in clinical dentistry, reducing manual workload and error rates. Future research will focus on expanding the dataset and further refining the model’s generalizability.

Ferula sp. is a perennial herbaceous plant and is used in traditional medicine owing to their antimicrobial, antiviral, aphrodisiac and spermatogenic activities in the world. Hence, Ferula sp. was used in the present study for cryopreservation protocol as a herbal supplement. The impact of different concentrations [0 mM (Control), 30 µg L−1, 60 µg L−1, 90 µg L−1] of Ferula sp. extract on the quality and fatty acid (FAs) composition was assessed in fresh and cryopreserved sperm of Cyprinus carpio. Optimal supplementation of Ferula sp. at a concentration of 60 µg L−1 in the freezing extender significantly improved post-thawed sperm quality of C. carpio. Sperm motility parameters were assessed using the sperm class analyzer system. The fatty acid (FAs) content in sperm was analyzed using gas chromatography. The results revealed that the increases in motility rate (80.0 ± 3.54%) at 60 µg L−1 were increased significantly (p < 0.05). Significant differences in sperm parameters [(VCL: curvilinear velocity, VSL: straight line velocity, VAP: average path velocity, and BCF: beat cross frequency)] were observed between the different treatments (p < 0.05). The Monounsaturated fatty acids (MUFAs) showed a slight increase in comparison to fresh spermatozoa during cryopreservation. DHA (Docosahexaenoic acid), LA (Linoleic acid) and ARA (Arachidonic acid) were identified as the major PUFAs (polyunsaturated fatty acid) in the sperm plasma membrane, and however the total PUFAs reduced all treated compared to fresh sperm samples after post-thawing. Overall, the supplementation with Ferula sp. to extender at a concentration of 60 µg L−1 positively influenced the motility parameters and FAs levels during cryopreservation and, Ferula sp. may act as a promising protective substance for the conservation of valuable fish genetic resources.

Ekici, Seymanur; Omac, Basri; Sabanci, Serdal
In this study, plum marmalade was prepared using the ohmic heating method at three distinct voltage gradients (30, 35, and 40 V/cm). The quality properties of the marmalade prepared this way were contrasted with those prepared using the conventional heating method. Total phenolic content (TPC), antioxidant activity (AA), vitamin C content, total color change (ΔE), hydroxymethylfurfural (HMF), and the amount of time needed for the process, including heating and evaporation, were all measured as part of the study. According to the findings, ohmic heating—specifically, a voltage gradient of 40 V/cm—significantly reduced the heating time when compared to the traditional method, which raised the stability of vitamin C, AA, and phenolic compounds. When ohmic heating was used instead of conventional heating, the amounts of TPC, AA, and vitamin C increased by 19.50%, 33.90%, and 149.12%, respectively. In comparison to traditional heating under atmospheric conditions, the results also showed that ohmic heating increased the amounts of gallic acid (40.61%), catechin (40.98%), chlorogenic acid (25.05%), and rutin (24.67%). Furthermore, the results showed that ohmic heating reduced the amount of HMF (34.34%) and ΔE (2.27%) in comparison to conventional heating. TPC, AA, vitamin C, gallic acid, catechin, chlorogenic acid, and rutin were higher than conventional heating; nevertheless, HMF and ΔE were lower than conventional heating at the applied ohmic heating process. The results obtained indicate a strong potential for an ohmic heating system as a rapid heating method for preserving nutritional value.

Background and Objectives: Coronavirus disease 2019 (COVID-19) has affected multiple physiological systems, including respiratory function, which is critical for athletic performance. Although alterations in pulmonary dynamics have been observed in high-level athletes recovering from COVID-19, the effects on respiratory function remain unclear. In this context, the present study aimed to examine the impact of COVID-19 on the interrelationships among respiratory function parameters in high-level athletes. Materials and Methods: Sixty-eight high-level athletes participated in the present study, including 34 with a history of COVID-19 and 34 controls without prior infection. Respiratory function and respiratory muscle strength were assessed using a digital spirometer (Pony FX, Cosmed, Italy). Key variables included Forced Vital Capacity (FVC), Peak Expiratory Flow (PEF), Maximum Voluntary Ventilation (MVV), Forced Expiratory Volume in one second (FEV1), and Maximum Inspiratory/Expiratory Pressure (MIP/MEP). Results: High-level athletes with prior COVID-19 infection exhibited significant differences in the correlations (p < 0.05) between FVC and PEF, FVC and MVV, FEV1 and FEV1/FVC, and MIP and MVV compared to controls. Conclusions: These findings suggest that COVID-19 can disrupt the interrelationships among respiratory function parameters in high-level athletes, highlighting the need for further longitudinal investigations.

Akarsu, Mehmet; Güllü, Mehmet; Günata, Gül Polat; Kızılkaya, Aysel; Aydın, Savaş; Özcan, Ecesu; Norman, Göktuğ; Kurhan, Cihad Onur
Background: It is well-established that, for adolescents to adopt sustainable healthy lifestyle behaviors, not only access to information but also the skills required to translate that information into action are critical. In this field, research that examines the relationship between e-health literacy and sustainable healthy lifestyle behaviors within the context of physical literacy is notably scarce. In this context, the aim of this study is to examine the effect of e-health literacy on a sustainable healthy lifestyle and to evaluate the mediating role of physical literacy in this relationship. Methods: A total of 835 adolescents from high schools across Türkiye voluntarily participated in this study. During the data collection process, the e-Health Literacy Scale, the Perceived Physical Literacy Scale, and the Healthy and Sustainable Lifestyle Scale were utilized. Data were analyzed using the JASP (version 0.18.3.0) software. Correlation analysis and structural equation modeling were conducted, and the bootstrap method (n = 5000) was employed for mediation analysis. Results: The effect of e-health literacy on a sustainable healthy lifestyle was found to be positive and statistically significant (β = 0.452, p < 0.001). Similarly, e-health literacy significantly predicted physical literacy (β = 0.755, p < 0.001), and physical literacy significantly predicted a sustainable healthy lifestyle (β = 0.310, p < 0.001). The mediating effect was also statistically significant (β = 0.234, p < 0.001). The model explained 32% of the variance in healthy lifestyle behaviors. Conclusions: The findings indicate that evaluating e-health literacy and physical literacy together provides a holistic approach to fostering sustainable healthy lifestyle habits among adolescents. It is recommended that intervention programs be structured to encompass both areas of competence.

Taşar, Neslihan; Torgut, Gülben
In the present study, a copolymer of poly(N,N-dimethylacrylamide) and sodium acrylate was synthesized with the Solution Polymerization Technique. The purpose was to uncover the cytotoxic and genotoxic effects on root tip cells of the Triticum aestivum L. plant germinated with this polymer at different concentrations (25, 50, 100, and 200 ppm). The deposition of poly(DMAA-co-NaAc) copolymer in the study sample T. aestivum was demonstrated with the FTIR, UV–VIS spectroscopy analysis, X-Ray Diffraction (XRD) Spectroscopy, Scanning Electron Microscopy (SEM), SEM Element Map, and Energy Dispersive Spectroscopy (EDS) Spectrum. All concentrations of the poly(DMAA-co-NaAc) copolymer caused a decrease in the Mitotic Index (MI). The poly(DMAA-co-NaAc) copolymer caused various mitotic abnormalities such as loss of genetic material, deconstructed prophase, adhesion, chromosome groupings in metaphase, deconstructed metaphase, C-metaphase, chromosomal loss, chromosomal fracture, deconstructed anaphase, lagging chromosome, fragment, polar aberration, bridge, advancing, star anaphase, multipolarity, and deconstructed telophase. Study results show that poly(DMAA-co-NaAc) copolymer will cause abnormalities in mitosis as a result of its uptake by plants. These results also show that the poly(DMAA-co-NaAc) polymer, which affects organisms, must be produced in a controlled setting to reduce its accumulation in nature and ultimately disposed of in a way that will not harm the environment.

The aim of this study was to examine the genotypes of wild blackberries growing naturally in Tunceli province in terms of fruit characteristics and to determine the ones with superior characteristics. Nine different genotypes were determined by population screening and 100 fruits were collected from each genotype. The physical properties such as fruit weight, length, width, as well as color, chemical content, and antioxidant properties were examined. Statistically significant differences were found among the genotypes; fruit weight, length, and width varied between 0.71 and 1.19 g, 10.08 and 12.63 mm, and 12.25 and 14.33 mm, respectively. The G9 genotype had the largest fruits, and the G6 genotype had the smallest fruits. In fruit color analyses, significant differences were observed among the genotypes, and the G2 genotype stood out with the highest L* value (20.05), but G9 had the lowest a* value (0.92). Total soluble solids (TSS) content varied between 11.95% in G2 and 21.10% in G7. Vitamin C content was highest in the G6 genotype (54.46 mg 100 g−1), while G9 had the lowest vitamin C content (22.66 mg 100 g−1). Significant differences were also observed among the genotypes in terms of phenolic content, flavonoids, anthocyanins, and antioxidant activity. As a result, in this study, significant differences in organic acid contents were determined among wild blackberry genotypes in Tunceli province. The G1 genotype was the richest in malic acid, while the G6 was the genotype with the highest ascorbic acid level. Various differences were also found among the genotypes in terms of oxalic acid, citric acid, and other organic acid contents. These findings may constitute an important resource in determining the commercial production and potential health benefits of wild blackberries. In the selection of blackberry genotypes, consideration of these organic acid contents is important, especially in terms of taste and nutritional value.

The emergence of multidrug-resistant bacterial strains has intensified the need for novel antimicrobial agents. Herein, we report a facile one-pot green synthesis of quercetin-stabilized silver (Qn@AgNPs) and copper (Qn@CuNPs) nanoparticles using quercetin as both reductant and capping ligand. The resulting nanocomposites were fully characterized by UV–Vis spectroscopy (surface plasmon resonance peaks at 420 nm for Ag and 580 nm for Cu), FTIR (confirming quercetin–metal coordination), SEM/EDX (spherical particles, and XRD (face-centered cubic Ag and Cu phases). Density functional theory (B3LYP/3-21G) calculations yielded frontier molecular orbital gaps of 0.164 eV for Qn@AgNPs and 0.245 eV for Qn@CuNPs, with corresponding high softness values (12.20 and 8.16 eV⁻¹), indicating enhanced electron-transfer propensity. Molecular electrostatic potential maps revealed increased charge polarization around the metal centers. Antibacterial assays against Escherichia coli and Staphylococcus aureus demonstrated minimum inhibitory concentrations of 2.11 ± 1.22 µg/mL and 4.69 ± 2.68 µg/mL for Qn@AgNPs, and 7.50 ± 0.00 µg/mL and 6.25 ± 0.17 µg/mL for Qn@CuNPs, significantly outperforming free quercetin (188 and 375 µg/mL). In silico docking against the S. epidermidis TcaR regulator (PDB: 1KZN) and E. coli DNA gyrase B (PDB: 1HSK) revealed strong binding affinities (–7.54 to − 10.15 kcal·mol⁻¹), consistent with the observed antimicrobial potency. This integrated experimental–computational study elucidates the mechanistic underpinnings of quercetin-mediated nanoparticle bioactivity and provides a rational framework for designing next-generation flavonoid-functionalized metal nanotherapeutics.

Utku, Anıl
Endoscopy is a procedure that allows examination of the gastrointestinal system, including the stomach, esophagus, large intestine, and duodenum, with the help of an endoscope. Processing of endoscopic images is important for early detection and treatment of gastrointestinal diseases. In this study, hybrid ConvViT was developed using CNN and ViT to increase the classification accuracy of pathologies in gastrointestinal endoscopic images. CNNs are well-suited for capturing local spatial features through hierarchical convolutions, making them highly effective in detecting fine-grained textures and edge patterns. These capabilities complement the ViT’s global attention mechanism, which excels at modeling long-range dependencies in images. The motivation of this study is to increase the classification accuracy and reliability with the ConvViT model, which was developed by combining the practical features of CNN and ViT models, which are individually successful in different aspects of image processing. The ConvViT model was compared with VGG-16, ResNet-50, Inception-V3 and ViT. Comparable models were tested using a gastrointestinal endoscopic image dataset containing ulcers, polyps, inflammation, bleeding, and regular anatomical features. Experiments showed that ConvViT had better prediction performance than compared models, with 95.87% classification accuracy.

Background: Sweet cherry (Prunus avium L.) is an important fruit species with its high nutritional value and fresh consumption rate. However, it is very sensitive to mechanical damage, decay, water loss and microbial spoilage in the post-harvest period. Therefore, new preservation methods are needed to extend shelf life and preserve quality. In this study, the effects of postharvest 4% calcium chloride (CaCl₂) and modified atmosphere packaging (MAP) treatments on quality traits (weight loss, decay rate, SSC, titratable acidity, pH, respiration rate) and biochemical compounds (organic acids, vitamin C and phenolic compounds) of sweet cherry fruit were investigated. Results: During the storage period, the weight loss reached 7.14%, the lowest loss was observed in the CaCl₂+MAP group. The highest decay rate was measured in the control group with 11.30%, and the CaCl₂+MAP combination was the method that limited decay the most. SSC increased over time, but the lowest levels remained in the CaCl₂+MAP group. The titratable acidity value decreased from 1.12% to 0.82%, CaCl₂+MAP application was the method that best preserved acidity. The pH value increased by 25.2%, the lowest pH was again determined in the CaCl₂+MAP group. The respiration rate decreased by 77%, the lowest respiration rate was determined in the CaCl₂+MAP application. Organic acid and vitamin C contents decreased over time, and the application that best limited these losses was CaCl₂+MAP. Significant decreases were also observed in phenolic compounds, and the combined application preserved phenolic stability at the highest level. Conclusion: CaCl₂ and MAP applications were effective in preserving the quality characteristics and bioactive compounds of sweet cherry fruit, especially the combined application (CaCl₂+MAP) gave the most successful results. Therefore, in order to prevent post-harvest quality losses and extend shelf life, it is recommended that CaCl₂ and MAP applications be evaluated together by the producer and the supply chain.
