- MakaleAçık Erişim2025Scopus SJRQ2Could GSTP1, PTEN and NKX3.1 gene expression be novel markers in the relationship between prostate cancer and epigenetics?
Koçak, Tevfik; Acar-Tek, Nilufer; Yesil, Suleyman; Ergün, Mehmet Ali; Icer, Yusuf
Background: Although numerous treatment modalities exist for Prostate Cancer (PCa) with a complex pathophysiology, a significant worldwide health concern for males, early identification remains the paramount factor influencing disease prognosis. Proposed new biomarkers, including GSTP1, PTEN, and NKX3.1, may provide predictive and prognostic functions, hence enhancing the efficacy of PSA in diagnosing prostate cancer. Epigenetic variables associated with nutrition influence the blood gene expression levels of the new biomarkers GSTP1, PTEN, and NKX3.1. This study aimed to elucidate the correlation between nutrition-related epigenetic variables and the expression of the tumor suppressor genes GSTP1, PTEN, and NKX3.1 in benign prostate and prostate cancer patients. Methods: This study was conducted with 41 newly diagnosed prostate cancer and 42 benign prostate patients, all aged 40 years and older. Participants had specific anthropometric measurements taken, and seven-day food records were kept. Serum levels of novel biochemical markers GSTP1, PTEN, and NKX3.1 were measured using an Enzyme-Linked Immunosorbent Assay (ELISA) method. Expression analyses of tumor-protective GSTP1, PTEN, and NKX3.1 genes were performed on prostate tissues obtained from fresh prostate biopsies taken from the groups and were associated with nutritional status. Results: A significant relationship was found between the serum levels of GSTP1, PTEN, and NKX3.1, which are important in the formation and treatment of prostate cancer, and Gleason grade, tumor stage, and surgical margin status (p < 0.05). However, significant relationships were found between many macro and micronutrients obtained from the dietary pattern and effective in epigenetic pathways and GSTP1, PTEN, and NKX3.1 gene expressions (p < 0.05). Conclusions: The findings of this investigation corroborated the notion that prospective novel markers, including GSTP1, PTEN, and NKX3.1, may serve predictive and prognostic functions in prostate cancer, hence enhancing the efficacy of PSA in its diagnosis. Dietary trends may influence the optimization of many epigenetic processes. Targeted therapeutic nutritional interventions designed to enhance gene expression will facilitate the formulation of prostate cancer prevention methods.

Dönmez, Cahit; Aral, Zehra Deveci; Saka, Samet; Günay, Kurtulus; Yildirim, Nail; Yildirim, Esra; Yagcioglu, Kiymet Deniz; Maqsud, Isoqov; Movlanov, Jakhongir; Dovronovich, Mamarozikov Usmonjon
The Central Asian Orogenic Belt's ophiolites lack a full ophiolitic succession and instead occur as irregular fragments and slices in tectonic melanges and accretionary complexes. The Teskuduk and Northern Nurata ophiolites in Uzbekistan comprise extensively serpentinized mantle rocks that contain minor podiform chromitites, situated in the western area of the southern Tien Shan belt. Chromites in this region are found in a very limited area, and this study aims to determine the geochemical properties and formation environments of chromites by conducting geochemical studies on a limited number of recently discovered chromitites. In this context, mineral chemistry and platinum group element (PGE) geochemistry analyses were carried out on chromites. For Teskuduk chromitites, the Cr2O3, Al2O3, and TiO2 contents range from 53.2 to 55.7wt%, 11.1 to 12.7wt%, and 0.14 to 0.20 wt%, respectively, whereas for Nurata chromitites, the corresponding values range from 36.2 to 37.2 wt%, 23.1 to 30.2 wt%, and 0.10 to 0.30 wt%. The Teskuduk and Nurata chromitites contain a total average of 370 ppb and 117 ppb PGEs, respectively. They are classified as unfractionated chromitites, with low Pd/Ir ratios (0.03-0.20). These chromitite samples have chondrite-normalized PGE patterns that are identical to Cr-rich mantle-derived chromitites found in subduction-related ophiolites. Collectively, these data suggest that the Teskuduk ophiolites formed in a forearc setting, whereas the Nurata ophiolites evolved in a back-arc setting within the same oceanic branch.

Objective: This study aimed to investigate the potential splenic tissue damage induced by radiotherapy (RT) and the potential protective effect of different doses of dexmedetomidine on this damage at the histopathological, immunohistochemical, and biochemical levels. Materials and Methods: In our study, Sprague Dawley rats were randomly divided into four groups: Control, Radiotherapy (RT; 8 Gy), RT + Dexmedetomidine 100 mu g/kg (RT-D100), and RT + Dexmedetomidine 200 mu g/kg (RT-D200). A single dose of 8 Gy radiotherapy was administered to each RT group. Spleen tissues were examined histologically with hematoxylin-eosin and immunohistochemically with anti-Caspase-3, anti-TGF-beta 1, and anti-TGF-beta 3 using light microscopy. TBARS and total thiol levels were also analyzed to assess oxidative stress and antioxidant capacity. Results: Histopathological results showed a significant decrease in white pulp diameter, decreased cellular density, and increased congestion in the red pulp in the RT group. Significant fibrosis, sinusoidal dilatation, vacuolization, and amyloid deposition were detected in the white pulp in the RT group. Regarding anti-caspase-3 immunoreactivity, strong positivity increased in the red pulp in the RT group, while a significant increase was observed in the white pulp in both the RT-D100 and RT groups. While the proportion of TGF-beta 1 immunopositive cells did not change significantly in the RT group, they increased significantly in both dexmedetomidine groups (especially RT-D200). TGF-beta 3 expression increased significantly only in the RT-D100 group. In biochemical analyses, TBARS levels increased significantly in the RT-D100 group. Total thiol levels decreased in the RT group and increased in the dexmedetomidine-treated groups. Conclusions: While RT caused histopathological damage and increased oxidative stress in spleen tissue, dexmedetomidine reduced this damage in a dose-dependent manner. The different immunohistochemical profiles of TGF-beta 1 and TGF-beta 3 suggest that these cytokines may have different functions in the spleen. 100 mu g/kg dexmedetomidine stimulates a regenerative response through TGF-beta 3, while 200 mu g/kg dexmedetomidine may provide immune regulation and antioxidative defense through TGF-beta 1.

İncele - MakaleAçık Erişim2025Scopus SJRQ2Geochronological and isotopic data from the adakitic Dodurga Pluton (Central Pontides, N Turkiye): new insights for the geodynamic evolution of the northern Neotethys
Çimen, Okay; Gücer, Mehmet Ali; Simonetti, Antonio; Karaoglan, Fatih
The Dodurga Pluton is located within the Central Pontides (northern Turkiye), has a SW-NE elongation, and consists of granodiorite and dacite porphyry. Previous studies have suggested that this pluton is Triassic in age, and its whole-rock geochemical systematics is consistent with that from adakitic magmatic occurrences rather than the classic arc granitoid suite. This study reports for the first time in situ/whole-rock radiogenic isotopic (Sr, Nd, and Pb) and mica/amphibole Ar-Ar age data to evaluate better its petrogenetic/geodynamic evolution and the chemical nature of mantle source(s). Unlike previous data, combined new in situ zircon U-Pb yield Late Cretaceous crystallization ages of 84.2 +/- 0.9 Ma and 86.9 +/- 0.9 Ma, and the Ar-Ar age data along with apatite fission track measurements suggest magma cooling extending to 82.3 +/- 0.4 Ma and 85.4 +/- 0.4 Ma, respectively. The apatite fission track (AFT) dating results also reveal that this pluton was buried at a depth of 2.5-3 km following a fast-cooling period during the Late Cretaceous and cooled/exhumed over similar to 2 km during the Middle-Late Miocene (15-10 Ma) in a slow cooling phase. The overall data reported here suggest that the Dodurga Pluton represents melts derived from an enriched/metasomatized mantle source that interacted with lower crustal mafic rocks in an active continental margin as a result of northward subduction of the northern branch of the Neotethys Ocean.

Ayaydin, Hasan; Ergün, Tolga; Barut, Abdulkadir; Erdem, Azad; Pilatin, Abdulmuttalip
The increasing emphasis on climate change and environmental sustainability worldwide has brought about the convergence and increased focus on financial technologies (FinTech) and green energy initiatives. In light of this, the study's objective is to investigate how FinTech moderates the relationship between the ecological footprint (EF) and green energy transition (GTE) in the BRICS-T nations between 1990 and 2021. This study examines how fintech moderated the GTE and EF in the BRICS-T from 1990 to 2021. We applied the Fully Modified Ordinary Least Squares (FMOLS) and used Dynamic Ordinary Least Squares (DOLS) as the main estimators for longitudinal analysis. In contrast, Driscoll-Kraay was used to verify the robustness of the results under cross-sectional dependence and heteroskedasticity. The results reveal that FinTech indirectly hinders EF by facilitating GTE. The outcomes also show that FinTech significantly constrains EF, while GDP and industrialization worsen EF. The results also confirm the important role of GTE and foreign direct investment (FDI) in reducing CO2 emissions in BRICS-T countries. Lastly, the paper offers policymakers useful recommendations for lowering EF in light of these outcomes. The study suggests establishing appropriate policies and strategies that encourage FinTech platforms to invest in green energy projects, including financial technology, promoting energy-efficient and low-carbon foreign direct investment, and encouraging GTE.

Can, Ibrahim; Yerlikaya, Gokhan; Bayrakdaroglu, Serdar; Ceylan, Halil Ibrahim; Subak, Guelhan Erdem; Bayrakdaroglu, Yesim; Uluç, Sinem; Nikolaidis, Pantelis T.
Background: This study examines the acute effects of neuromuscular electrical stimulation (NMES) application on peak power (PP) and mean propulsive power (MPP) during a weighted squat jump (SJ(Loaded)). Methods: Fourteen male students (age: 23.71 +/- 2.30 years; height: 173.71 +/- 6.89 cm; weight: 69.59 +/- 9.08 kg; body mass index (BMI): 26.87 +/- 3.49) from the Faculty of Sport Sciences participated voluntarily. PP and MPP values were measured during the SJ(Loaded) movement, performed with an external load of 40% body weight, using a computer-integrated linear velocity transducer system (T-Force Dynamic Measurement System Ergotech Consulting SL, Murcia, Spain). NMES was bilaterally applied to the musculus hamstring and musculus quadriceps femoris for 20 minutes. The Shapiro-Wilk test, skewness and kurtosis values assessed data normality. Results: Differences between pre- and post-test PP and MPP power performances were analyzed using Paired Samples t-tests. Cohen's d (ES: effect size) and 95% confidence intervals (CI) were also calculated to assess the pairwise comparisons' magnitude. According to the analysis results, statistically significant improvements were observed in both PP (t (13) = -2.612, p = 0.021, d: -0.69 (-1.27; -0.10, 95% CI)) and MPP (t (13) = -2.756, p = 0.016, d: -0.73 (-1.32; -0.13, 95% CI), moderate effect) values after the NMES application. Conclusions: NMES significantly enhances PP and MPP during loaded squat jumps, highlighting its potential as a supplementary training tool for improving explosive power. Future studies should explore its long-term effects across different sports and populations, such as female athletes or older adults, to optimize training protocols. Research on NMES intensities and frequencies may provide insights into optimal parameters for power development and neuromuscular adaptation.

Erdogan, Perihan Mutlu; Bilgili-Tetikoglu, Funda; Çelik-Uzuner, Selcen; Yildiz, Oktay; Kolayli, Sevgi; Mossialos, Dimitris
Honey bee (Apis mellifera) products have been extensively utilized in traditional medicine. Bee venom (BV) is one of the major bee products with a high concentration of the small peptide melittin (MEL) and exerts bioactivity ranging from anti-microbial to anti-inflammatory and anti-cancer. This scoping review aims to sum up research articles on the bioactivity exerted by BV and MEL published in PubMed and Scopus from 2010 onwards. PRISMA guidelines were implemented to analyze the relevant literature; we ended up with 425 research articles. Bioactivity of BV and MEL was grouped as (i) anti-inflammatory (85), (ii) immunomodulatory (37), (iii) anti-microbial (179), (iv) anti-cancer (170), and (v) anti-oxidant (32). Although there is a significant body of research on the anti-cancer and anti-microbial activity of BV and MEL, their anti-oxidant, anti-inflammatory and immunomodulatory properties have received comparatively less attention. Many studies on the immunomodulatory effects of BV or MEL have focused on cancer. However, the effects on Parkinson's and Alzheimer's disease have not been extensively studied regarding the anti-inflammatory effects. Given the critical role of the immune system and inflammatory response in cancer, neurodegenerative diseases, senescence and against infections, it is paramount to further explore the immunomodulatory and anti-inflammatory potential of BV and MEL.

Background:This quasi-experimental crossover study aimed to examine the acute effects of dry cupping therapy (DCT) and neuromuscular electrical stimulation (NMES) on fatigue and perceived exertion in anaerobic performance among physically active individuals.Methods:Twelve male participants (mean age: 24.1 +/- 2.37 years), all students from the Faculty of Sports Sciences, were recruited to participate voluntarily. Anaerobic performance parameters, including peak power, mean power (MP), and fatigue index (FI), were assessed using a Monark 839E cycling ergometer under 3 distinct conditions: NMES, DCT, and a control condition (no intervention), with each session separated by a 48-hour rest period. Perceived exertion was evaluated immediately following each test session using Borg's rate of perceived exertion (RPE) scale. Both NMES and DCT were administered bilaterally to the hamstring (m. hamstring) and quadriceps femoris (m. quadriceps femoris) muscles for 20 minutes before testing.Results:The results revealed no statistically significant differences in peak power and MP across the conditions. However, significant effects were identified for FI (F(2, 22) = 4.08, P = .031, eta p(2) = 0.27) and RPE (F(2, 22] = 8.88, P = .0015, eta p(2) = 0.45). Post hoc pairwise comparisons indicated that NMES significantly reduced FI compared to the control condition (P = .0311), with a small to medium effect size (Cohen's d = 0.44). In terms of RPE, DCT significantly lowered values compared to both the control (P = .0018) and NMES conditions (P = .0005), demonstrating medium (Cohen's d = 0.74) and small to medium (Cohen's d = 0.37) effect sizes, respectively.Conclusions:While NMES and DCT did not elicit acute improvements in peak or mean anaerobic power, both interventions effectively mitigated fatigue and reduced perceived exertion during maximal anaerobic exercise. These findings suggest that NMES and DCT may serve as valuable recovery modalities for mitigating fatigue in sports characterized by high anaerobic demands. Future research should investigate the chronic effects of these interventions and explore their utility among trained athletes to determine their broader applicability in enhancing athletic performance.

Corruption involves greed, money, and risky decision-making. We explore the love of money, pay satisfaction, probability of risk, and dishonesty across cultures. Avaricious monetary aspiration breeds unethicality. Prospect theory frames decisions in the gains–losses domain and high–low probability. Pay dissatisfaction (in the losses) excites dishonesty in the name of justice at the individual level. Corruption Perceptions Index, CPI, signals a high–low probability of getting caught for dishonesty at the country level. We theorize: Decision-makers adopt avaricious love of money aspiration as a lens and frame dishonesty in the gains–losses domain (pay satisfaction–dissatisfaction, Level 1) and high–low probability (CPI, Level 2) to maximize expected utility and ultimate serenity. We challenge the myth: Pay satisfaction curbs dishonesty across nations consistently. Cross-level three-dimensional visualization demonstrates (6500 managers in 32 countries across six continents): With high aspiration, pay dissatisfaction excites the highest- (third-highest) avaricious justice-seeking dishonesty in high (medium) CPI nations; pay satisfaction provokes the second-highest avaricious opportunity-seizing dishonesty in low CPI entities—maximizing expected utility. Low aspiration and high pay satisfaction consistently create low dishonesty—achieving ultimate serenity. We expand prospect theory from a micro and individual-level theory to a cross-level theory of monetary wisdom across 32 nations, providing novel insights to business ethics, the environment, and responsibility.

Gait recognition aims to identify people from a distance by analyzing their walking style. Nevertheless, the efficacy of recognition drops significantly under cross-view and, appearance-based variations such as carrying and clothing. In this study, the performance of the MobileNet-V1 deep network is evaluated in various scenarios to address the cross-view gait recognition problem. In the first scenario, the fine-tuned MobileNet-V1 is evaluated on Gait Energy Images (GEI) as input data, while in the second scenario, the fine-tuned MobileNet-V1 is assessed with Optical Flows and masked RGB frames input data. In the last scenario, the first two scenarios are combined over a single fused deep network based on finetuned MobileNet-V1, and a single recognition process is performed using two different fused features data; GEI features with Optical Flow features, and GEI features with masked RGB frame features. In the evaluation process, a comprehensive data set for the cross-view gait recognition problem, CASIA-B is used for the experiments. The obtained results demonstrate that in the last scenario, the contribution of masked RGB frame features to the recognition rate of GEI is more significant.

Kayln, Sercan; Işseven, Turgay
One of the major challenges facing geochemistry, petrology, and volcanology researchers is the difficulty in determining the origin and paleo-flow directions of igneous and volcanic rocks. It is not possible to clearly determine origins and paleo-flow directions in areas with numerous volcanic centers. Anisotropy of magnetic susceptibility (AMS) is a valuable method that provides insights into the origins and paleo-flow directions of lavas that are complex to study. The presence of volcanic materials with thicknesses up to 1 km, coming from different sources at varied time intervals in the north of Lake Van, makes this area an ideal setting for implementing AMS in establishing paleo-flow directions. This study presents the magnetic mineralogy and AMS analysis of volcanic rocks from the Miocene to the Quaternary in the Lake Van region. We conducted isothermal remanent magnetization (IRM) and high-temperature susceptibility (HTS) studies to determine the magnetic mineralogy. IRM studies revealed that (titano)magnetite is responsible for the magnetization in most samples, while both (titano)magnetite and hematite are responsible for the rest. Alteration degrees and Curie temperatures of the rock samples were also determined through HTS measurements. There is good agreement between the anticipated directions of lava flow and our findings for nearly all volcanic rocks.

The compound 5-(hydroxymethyl)furfural (HMF) has emerged as a versatile intermediate with the ability to undergo conversion into both fuel and a variety of platform chemicals. Lignocellulosic biomass, such as hazelnut shells and tea processing residues, was employed in this study for HMF production through two distinct methods. In the first method, cellulose from biomass was converted to sugars using a 4% acid solution, followed by catalytic conversion with NaCl/CrCl3.6H2O. After a 1-h reaction at 131 °C in a high-pressure system, HMF was obtained from tea processing waste and hazelnut shells with yields of 8.6% (82.3 mg/g) and 6.7% (66.7 mg/g), respectively. The second method involved LiCl/NaCl-doped N,N-dimethylacetamide (DMA) as an ionic solvent system for HMF production. After a 2-h reaction at 131 °C in the DMA-NaCl/[EMIM]Cl ionic solvent system, HMF was obtained from tea processing waste and hazelnut shell celluloses with yields of 5.7% (57.5 mg/g) and 3.1% (31.3 mg/g), respectively. This study contributes to the economic conversion of various food wastes into valuable chemicals, highlighting the potential of lignocellulosic biomass in sustainable chemical production.

Ulutaşdemir, Nilgün; Ay, Halil; Göçmen, Adalet; Uzun, Sevda; Kulakaç, Nurşen
OBJECTIVE: To determine the practices and coping experiences of the relatives of patients with pressure injuries (PIs). METHODS: The authors used a qualitative, phenomenologic research design. They interviewed 20 relatives of patients with PIs face-to-face using an in-depth semistructured interview form. The data were analyzed using the Colaizzi phenomenologic method. RESULTS: Three categories, 8 main themes, and 22 subthemes emerged from the interviews. The category of “the impact of the need for care on the lives of the patient’s relatives” was analyzed according to psychological, social, and physical effects. In the category of “practices to prevent pressure injuries,” two themes emerged: practices toward the patient and the environment. Relatives of individuals with PIs have psychological, physical, and social needs. CONCLUSIONS: Providing care to a patient with PIs has psychological, social, and physical effects on the patient’s relatives. The care burden mostly affects these caregivers negatively, and they mainly need time for themselves and moral and companion support.

This paper presents a sentiment analysis combining the lexicon-based and machine learning (ML)-based approaches in Turkish to investigate the public mood for the prediction of stock market behavior in BIST30, Borsa Istanbul. Our main motivation behind this study is to apply sentiment analysis to financial-related tweets in Turkish. We import 17189 tweets posted as "#Borsaistanbul, #Bist, #Bist30, #Bist100″ on Twitter between November 7, 2022, and November 15, 2022, via a MAXQDA 2020, a qualitative data analysis program. For the lexicon-based side, we use a multilingual sentiment offered by the Orange program to label the polarities of the 17189 samples as positive, negative, and neutral labels. Neutral labels are discarded for the machine learning experiments. For the machine learning side, we select 9076 data as positive and negative to implement the classification problem with six different supervised machine learning classifiers conducted in Python 3.6 with the sklearn library. In experiments, 80 % of the selected data is used for the training phase and the rest is used for the testing and validation phase. Results of the experiments show that the Support Vector Machine and Multilayer Perceptron classifier perform better than other classifiers with 0.89 and 0.88 accuracy and AUC values of 0.8729 and 0.8647 respectively. Other classifiers obtain approximately a 78,5 % accuracy rate. It is possible to increase sentiment analysis accuracy with parameter optimization on a larger, cleaner, and more balanced dataset by changing the pre-processing steps. This work can be expanded in the future to develop better sentiment analysis using deep learning approaches.

The Late Cretaceous magmatic history of the Eastern Pontides Orogenic Belt (NE Turkey) was generally characterized by common I-type and lesser A-type plutons in varying size and composition. Of these, A-type plutons from the Şebinkarahisar (Giresun) area yield SHRIMP zircon U-Pb age of 77.36 ± 0.96 Ma. The rocks of these plutons display a wide range of SiO2 contents (53.63 to 70.96 wt.%) and Mg-numbers (6.2–32.19) with A-type affinities characterized by enrichment in K2O and Na2O, Ga, Zr, and strong negative Eu anomalies. They also show arc-type petrochemical features including enrichment of large-ion lithophile elements (e.g. Cs, K, Rb) and light rare earth elements (LaN/LuN = 6.27–15.61), but depletion in high strength field elements (e.g. Nb, Ta, Ti, and P). The (87Sr/86Sr)i ratios and ɛNd(i) values of the studied rocks are in the range of 0.705129 to 0.0705347 and −3.64 to −3.12, respectively, while bulk rock ɛHf(i) values are between 1.86 and 4.36. They are characterized by positive zircon ɛHf(i) (1.74 to 10.88) plotting between the chondrite and depleted mantle evolutionary line values. Our data combined with the previous studies suggest that the magmas, that formed the Late Cretaceous plutons, were generated in an extensional tectonic environment due to slap roll-back and trench ward migration of the subduction zone to the south. The generation of hybrid magmas forming the studied plutons is in response to the melts derived from a metasomatized lithospheric mantle source, a relatively deeper mantle source, and the juvenile crust along with the heat transfer and decompression. Multi-sourced magmas rise through the continental crust and reach the final composition by predominantly fractional crystallization processes.

Among these, palmprint biometrics has gained increasing attention for its advantages, such as ease of use, a larger surface area, and the ability to capture more features compared to other biometric methods. A typical palmprint biometric system involves five key stages: (a) Image Acquisition, (b) Hand Segmentation, (c) Pattern Generation, (d) Feature Extraction, and (e) Verification/Identification. The overall success of the system depends on the effectiveness of each stage, with hand segmentation being crucial for identifying the most relevant features for accurate verification. This study aims to achieve high-accuracy biometric recognition by segmenting hands from images captured in uncontrolled environments with complex backgrounds. Accuracy (ACC), Intersection over Union (IoU), F1-Score, and Dice Coefficient are the four critical metrics used to assess the performance of segmentation techniques. The findings demonstrate that the U-Net + ViT and MA-Net + ResNet34 techniques outperform traditional auto-encoder methods in both quantitative performance metrics and visual analysis, leading to significantly improved hand segmentation for biometric systems.

Negative attitudes and beliefs leading to discrimination against individuals with obesity and to their exclusion can cause these individuals to experience various biological, psychological, and social problems. Nursing students constitute the group that will provide care, services, and counseling to individuals with obesity in the future. The present study was aimed at determining the relationship between nursing students’ attitudes toward and beliefs about individuals with obesity and their empathy and body image flexibility levels. This study that has a cross-sectional correlational research design was conducted with 445 students studying at Dokuz Eylül University Faculty of Nursing between February 2023 and July 2023. The Sociodemographic Information Form, Beliefs About Obese Persons (BAOP) scale, Attitudes Toward Obese Persons (ATOP) scale, Body Image Flexibility Scale (BIFS), and Toronto Empathy Scale (TES) were used as data collection tools. In order to ensure explanatoriness in the analysis of the data, the multiple regression/ correlation analysis was performed to determine the relationship between the scores for the overall BAOP and ATOP scales, which were dependent variables, and BMI and the scores for the overall TES and BIFS, which were the independent variables. The mean scores that the students participating in this study obtained from the overall BAOP and ATOP were 23.89 ± 4.49 and 72.48 ± 11.19, respectively. The mean scores they obtained from the overall TES and BIFS were 51.61 ± 8.80 and 52.19 ± 15.28, respectively. The results demonstrated that higher levels of empathy and body image flexibility were significantly associated with lower levels of negative beliefs about individuals with obesity (B = −0.107, p =.026; B = 0.271, p <.001) and positive attitudes toward individuals with obesity (B = −0.143, p =.002; B = 0.343, p <.001). In the study, as the students’ empathy and body image flexibility levels increased so did their positive perceptions toward individuals with obesity. Nurses should acquire empathic skills during their education in order to demonstrate an equitable and inclusive approach to care and to provide positive health experiences to individuals with obesity. In order for young people studying at university to be more responsive to others, they should be encouraged to develop body image flexibility for their own and others’ bodies. It is also recommended that topics on combating stigma and discrimination to prevent negative attitudes toward and beliefs about individuals with obesity should be added to the curriculum of nursing students.

The sexual abuse of the child is a wide-ranging and complex problem with physical, emotional and psychological consequences, with social, moral, cultural and legal dimensions, and when the prevalence rates are analyzed, it is seen that it is a serious problem for all societies. One of the most common strategies used to prevent child sexual abuse is school-based initiatives. So, the purpose of this integrative literature review is to systematically evaluate the evidence of the effectiveness of school-based child sexual abuse prevention programs. In this context, the current study includes 22 articles that meet the criteria for inclusion. The Comprehensive Meta-Analysis (CMA) statistical program was used to calculate the effect sizes of the studies included in the meta-analysis. The mean, standard deviation, sample size, p, t, or f value data reported in the primary studies were used to calculate the effect sizes of the studies included in the meta-analysis. As a result of the analyzes carried out within the scope of the study, it was concluded that school-based education practices aimed at preventing child sexual abuse are highly effective, and that after the prevention programs, the knowledge and skill levels of the children increased widely and these increases were statistically significant. As a result, it can be said that the knowledge and self-protection skills of children can be increased by participating in school-based sexual abuse prevention programs.
