A Rare Cause of Dysphagia: A Giant Ganglioneuroma in Parapharyngeal Space
(Springer, 2022) Aslan, Mehmet; Dogukan, Fatih Mert
Parafarengeal ganglioneuroma is a very rare benign tumor originating from the sympathetic nervous system that produces mass and functional effects. Ganglioneuroma is most commonly caused by the posterior mediastinal, retroperitoneal area and adrenal glands. Generally, they do not present any additional signs or symptoms other than mass. Horner’s syndrome may sometimes occur due to the compression of the sympathetic chain. A 41-year-old male patient with a long-standing mass in the lateral compartment of the left neck was admitted to our clinic. The patient was operated, and the pathological result of the mass was reported as ganglioneuroma. We present a rare case of ganglioneuroma in paraphryngeal space by reviewing the current literature. © 2022 Elsevier B.V., All rights reserved.
A Rare Cause of Dysphagia: Giant Lipoma in Parapharyngeal Space
(Lippincott Williams and Wilkins, 2020) Aslan, Mehmet; Ozer Ozturk, Ebru; Dogukan, Fatih Mert
Background: Parapharyngeal area is one of the most complex areas of head and neck anatomy. Tumors of the parapharyngeal region are very rare among head and neck tumors. Lipomas also constitute a tiny proportion of parapharyngeal tumors so parapharyngeal area lipomas are very rare in the literature. Due to anatomical location, these tumors treatment is challenging. Clinical Report: A 20-year-old male patient admitted to our department with complaints of swallowing difficulty and a mass on the right side of the neck. Magnetic resonance imaging was performed, and it was reported as a 6 4.5 cm lipoma. He underwent excision of parapharyngeal area lipoma by a transoral approach. Conclusion: Parapharyngeal lipomas are very rare, and difficult to diagnose before they turn out symptomatic. The primary treatment approach in tumors of the parapharyngeal area is surgery and the surgical approach should be chosen according to the anatomical location of the lesion. © 2021 Elsevier B.V., All rights reserved.

(CZECH ACADEMY AGRICULTURAL SCIENCES, 2017) Türkölmez, Şahimerdan; Derviş, Sibel; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Crown and root rot, caused by the Oomycete pathogen Phytophthora palmivora, has become a destructive disease of apricot and cherry in eastern Turkey. There are no currently registered fungicides labeled for its control. In greenhouse experiments conducted in 2012 and 2013, 1-year-old potted apricot rootstock Zerdali and cherry rootstock Mahaleb plants were treated either with foliar spray of fosetyl-Al (140, 160, and 180 g a.i./100 l) or phosphorous acid (187.5, 200, and 215 g a.i./100 l) or soil drench of 100 ml of metalaxyl-M (= mefenoxam)+mancozeb (12+192, 16+256, and 20+320 g a.i./100 l) one day after wound inoculation of crowns and roots. In both years, phosphorous acid at 200 and 215 g a.i./100 l, fosetyl-Al at 160 and 180 g a.i./100 l, and metalaxyl-M+mancozeb at 20+320 g a.i./100 l significantly reduced the root rot severity on Zerdali by 70.68-80.00% and crown rot severity on both Zerdali and Mahaleb, by 68.32-91.96 and 74.21-82.60%, respectively, compared with phosphorous acid at 187.5 g a.i./100 l, fosetyl-Al at 140 g a.i./100 l, metalaxyl-M+mancozeb at 12+192 and 16+256 g a.i./100 l and control. Moreover, fosetyl-Al at 180 g a.i./100 l and metalaxyl-M+mancozeb at 20+320 g a.i./100 l significantly reduced the root rot severity on Mahaleb compared to fosetyl-Al at 140 and 160 g a.i./100 l, metalaxyl-M+mancozeb at 12+192 and 16+256 g a.i./100 l, phosphorous acid treatments and control in 2012, providing the best control of the disease by 88.00-90.68%. Two/three phosphorous acid foliar applications at 200 g a.i./100 l suppressed symptom development when field applications were made on a curative basis in 2014 and 2015.

(Soc Argentina Pediatria, 2024) Talay, Mehmet N.; Gungor, Emre; Orhan, Ozhan; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Introduction : Cyanide poisoning, whether it be accidental or intentional, remains a significant danger to adults and children, especially in societies where agriculture is a primary source of income. We examined the clinical follow-up, complications, and results of cyanide poisoning cases that occurred after eating the pits and seeds of plants containing cyanide glycosides, such as apricot kernels and almonds. Methods : Between 01/01/2017 and 01/08/2022, 14 children aged 1-18 years who were followed up with a prediagnosis of cyanide poisoning in our Paediatric Intensive Care Unit (PICU) were retrospectively analysed. Results : Eight of the patients followed with a preliminary diagnosis of cyanide poisoning were female and six were male. The most common admission month was July (42.8%) coinciding with the agricultural season. The most common symptoms at presentation were weakness and fatigue (n = 7). In the PICU, 4 patients presented lip cyanosis; 3, altered level of consciousness. Vomiting, seizure, headache, dizziness and palpitatons were less frequent. Four patients were treated with hydroxocobalamin (Cyanokit (R) ) as an antidote due to acidosis in their blood gases. All patients treated for cyanide poisoning were discharged. Conclusions : Cyanide poisoning should be considered in paediatric patients with suspicious findings, sudden loss of consciousness, increased anion gap acidosis and lactic acidosis. The history of eating the seeds of plants such as apricot and almonds should be investigated .

PurposeThis study aims to prevent mild steel (MS) against corrosion in 0.5 M HCl solution, 2-amino-4-methoxy-6-methyl-1,3,5-triazine was used. The effectiveness of the compound as a corrosion inhibitor was studied via electrochemical, surface and theoretical calculation techniques. Design/methodology/approachFor concentrations ranging from 0.5 to 10.0 mM, almost similar polarization resistances were obtained from electrochemical impedance spectroscopy (EIS) and linear polarization resistance tests. It also investigated inhibitive activity of 2-amino-4-methoxy-6-methyl-1,3,5-triazine on the steel surface using scanning electron and atomic force microscope instruments. Langmuir adsorption is the best matched isotherm for the adsorption of the inhibitor to the steel surface. FindingsEIS method was used to determine inhibition efficiency, which was determined to be 95.7% for 10.0 mM inhibitor containing acid solution. Density functional theory's predictions for quantum chemistry agreed well with the other experimental results. Originality/valueThe methods used in this study are effective and applicable; the used organic inhibitor is 2-amino-4-methoxy-6-methyl-1,3,5-triazine; and protective effectiveness is important, which is crucial for the task of MS corrosion prevention.

Air Quality Forecasting Using Machine Learning: Comparative Analysis and Ensemble Strategies for Enhanced Prediction
(Springer Int Publ Ag, 2025) Ozupak, Yildirim; Alpsalaz, Feyyaz; Aslan, Emrah; 08.01. Department of Computer Engineering / Bilgisayar Mühendisliği Bölümü; 08. Faculty of Engineering and Architecture / Mühendislik Mimarlık Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Air pollution poses a critical challenge to environmental sustainability, public health, and urban planning. Accurate air quality prediction is essential for devising effective management strategies and early warning systems. This study utilized a dataset comprising hourly measurements of pollutants such as PM2.5, NOx, CO, and benzene, sourced from five metal oxide sensors and a certified analyzer in a polluted urban area, totaling 9,357 records collected over one year (March 2004-February 2005) from the Kaggle Air Quality Data Set. A comprehensive comparison of ten machine learning regression models XGBoost, LightGBM, Random Forest, Gradient Boosting, CatBoost, Support Vector Regression (SVR) with Bayesian Optimization, Decision Tree, K-Nearest Neighbors (KNN), Elastic Net, and Bayesian Ridge was conducted. Model performance was enhanced through Bayesian optimization and randomized cross-validation, with stacking employed to leverage the strengths of base models. Experimental results showed that hyperparameter optimization and ensemble strategies significantly improved accuracy, with the SVR model optimized via Bayesian optimization achieving the highest performance: an R2 score of 99.94%, MAE of 0.0120, and MSE of 0.0005. These findings underscore the methodology's efficacy in precisely capturing the spatial and temporal dynamics of air pollution.
Ameliorative Effects of Agomelatine Against Doxorubicin-Induced Hepatotoxicity
(BMC, 2025) Savas, Hasan Basri; Sozen, Mehmet Enes; Cuce, Gokhan; Batur, Tuba
Drug-induced hepatotoxicity is a significant impediment to the use of doxorubicin, a commonly employed chemotherapeutic agent with established efficacy in cancer treatment. The present study aimed to determine the potential protective effects of agomelatine against doxorubicin hepatotoxicity in rat toxicity models. Thirty-two rats were divided into four groups: control (with saline administration), Doxo (with 40 mg/kg doxorubicin administration), Doxo + Ago20, and Doxo + Ago40 (with 20 and 40 mg/kg agomelatine administration and 40 mg/kg doxorubicin administration). On the day of 14 rats were sacrificed, samples were collected for comparison of immunohistochemical, hematological, and biochemical analysis. There were statistically significant differences between the study groups in terms of immunohistochemical, hematological, and biochemical parameters. Agomelatine administration reduced the TNF-alpha, and caspase-3, which increased by doxorubicin, and reversed levels of oxidative stress markers altered by doxorubicin (p < 0.05). Doxorubicin induces oxidative stress, apoptosis, and hepatotoxicity. Agomelatine may be favored as a primary antidepressant to mitigate hepatic damage induced by doxorubicin.

(Mashhad Univ Med Sciences, 2025) Karabekir, Seda Cetinkaya; Sozen, Mehmet Enes; Ayan, Ilknur Cinar; Savas, Hasan Basri; Cuce, Gokhan; Kalkan, Serpil; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Objective(s): Deltamethrin (DLM) is a widely used insecticide in agriculture; however, exposure to it can lead to serious health problems. This study aimed to evaluate the protective effects of hesperidin (HSP), a natural antioxidant, against DLM-induced liver toxicity. Materials and Methods: Thirty-two male Wistar Albino rats (250-300 g, 4 months old) were divided into four groups. The control group received 1 ml of corn oil via oral gavage for 30 days. The DLM group received 1.28 mg/kg DLM in corn oil for 30 days. The DLM+HSP 100 mg/kg and DLM+HSP 300 mg/kg groups received 1.28 mg/kg DLM followed by 100 mg/kg or 300 mg/kg HSP in distilled water, respectively, 30 min after DLM administration for 30 days. Liver tissues were examined histopathologically. Masson's trichrome staining and PCR assessed fibrosis. Caspase 3 and 9 expressions in liver tissues were determined by immunohistochemistry and PCR. Biochemical analyses were conducted on serum samples. Results: HSP supplementation led to a dose-dependent decrease in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. DLM exposure decreased antioxidant capacity, while HSP supplementation increased it dose-dependently. Histopathological evaluations showed increased liver damage in the DLM group, while HSP administration reduced liver toxicity. Masson's trichrome staining and analysis of collagen I (COL1A1) and collagen III (COL3A1) gene expression revealed increased fibrosis in the DLM group, which was attenuated with HSP treatment. Conclusion: The potential prevention of DLM-induced liver toxicity and apoptosis by HSP may be an alternative protective strategy.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was the cause of the coronavirus 2019 (COVID-19), commonly known as the coronavirus pandemic. Since December 2020, COVID-19 vaccines have been extensively administered in numerous countries. In addition to new antiviral medications, the treatment regimen encompasses symptom management. Despite sustained research efforts, the outbreak remains uncontrolled, with affected patients still lacking proper treatment. This review is a valuable asset for researchers and practitioners aiming to delve into the yet unexplored potential of Anatolian flora in the fight against COVID-19 and other viral infections. Numerous medicinal plants in Anatolia, such as thyme, sage, cannabis, oregano, licorice root, and Origanum sp., contain bioactive compounds with proven antiviral properties that have been used in the region for centuries. The rich legacy of traditional Anatolian medicine (TAM), has significantly influenced modern medicine; thus, the profusion of medicinal plants native to Anatolia holds promise for antiviral drug development, making this review essential for researchers and practitioners.

Animal Remains of Alaybeyi Hoyuk
(Tubitak Scientific & Technological Research Council Turkey, 2019) Siddiq, Abu Bakar; 02.01. Department of Anthropology / Antropoloji Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
This paper presents the zooarchaeological observations on animal remains of Alaybeyi Hoyuk unearthed from 2016 and 2017 excavation sessions. Dated to 4721-4553 cal. BC, Alaybeyi stands so far as the oldest archaeological settlement discovered in northeast Anatolia. Therefore, the faunal assemblage at Alaybeyi offers great opportunity to study the status of animals and their relationships with humans in the largely unexplored Kars-Erzurum plateau covering a period from the Chalcolithic to Late Iron Age. Taxonomic and osteometric analyses show that, like the present day, cattle were dominant over caprines, revealing extensive cattle pastoralism in the region for at least about 7 millennia. While caprines too were significant in the subsistence strategy of local humans, there was not any sign of raising pigs. Significant numbers of wild species including carnivores, aquatic mammals, and rodents, as well as resident and migratory birds, were also hunted by Alaybeyi people. Additionally, horse burials, horse cult, dog burials, and a rich number of dog bones present animals as versatile actors in various ritual and symbolic practices at the site.

(Gazi Universitesi, Turk Kulturu ve Haci Bektas Veli, 2017) Akyüz, Ç.; 02.15. Department of Turkish language and Literature / Türk Dili ve Edebiyatı Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Mountain is believed to keep the earth "stand straight" and conceived as a space of God to carve out the highest point of the earth. They shape traditional practices and social life as a cult in the old Turkish belief system. It contains rushing rivers, the springs and the sources of rivers. Water is the source of the material and spiritual life and it is considered to be sacred. In this regard, it can be said that many sacred narrative formed around the mountains and the water. Mountain and cave are also contemplation places for divine personality. Huseyin Gazi, one of the saints in Anatolia, who is believed to live in Mamak, Ankara, there is a mountain and a tomb by his name and stories associated with his sacred personality. Water metaphor is also noteworthy in a dialectical interaction with both mountain and Huseyin Gazi is blessed in this stories. In this regard, such stories refer naming the places in the context of the sacred mountain and cave metaphores and providing information about the origin of water resources in the context of the metaphor of holy water. In this study, stories that talk about Huseyin Gazi are handled in the context of mountain, water, and cave cults by analyzing printed materials and interviewing people. The issues of evolvement of historical personalities into phenomenon and mythical place names are also studied.Within this faremework in the foregoing verbal data about Huseyin Gazi indicates that his holy personality passes ahead of his historical personality.

(Centenary University, 2025) Güler Güney, İnci
In this study, endophytic bacteria were isolated from roots and crowns of rosemary (Rosmarinus officinalis L.), olive (Olea europaea L.), and loquat (Eriobotrya japonica L.) plant samples. The morphological and physiological properties of nine isolated endophytic bacteria were determined. All isolates were identified as Gram-positive, oxidase-positive and catalase-positive. Amylase, cellulase, and carbohydrate tests gave positive results. Antagonistic activities of the isolates against fungal pathogens varied between 85.7% and 52.9% against Fusarium culmorum and between 86.0% and 65.1% against Neoscytalidium dimidiatum. BMBA2 isolate gave the best results both in Petri dish antagonistic activity and in wheat seed germination in terms of root length and coleoptile length. BMBA2 isolates gave the best results with a coleoptile length of 7.58 cm and root length of 8.33 cm. In wheat seeds treated with F. culmorum and bacteria, the BMBA2 isolate gave the best result with a coleoptile length of 6.98 and a root length of 7.30 cm. For the identification of bacteria, in vitro BiBA1 and ND3BA were determined as Bacillus amyloliquefaciens subsp. plantarum; BiBA2 and YDBA as Bacillus subtilis; NDBA, ND2BA, BMBA1, BMBA2, and BMBA3 as Bacillus mojavensis. Since this is the first study to use endophytic Bacillus mojavensis as a biological agent against F. culmorum and N. dimidiatum pathogens, the results obtained from this study are thought to be important and promising in terms of application. © 2025 Elsevier B.V., All rights reserved.

Background: Cancer is an unnatural type of tissue growth in which the cells exhibit unrestrained division, leading to a progressive increase in the number of dividing cells. It is now the second largest cause of death in the world. The present study concerned antioxidant, anticancer and anticholinesterase activities and protocatechuic, catechin, caffeic acid, syringic acid, p-coumaric acid and o-coumaric concentrations in methanol extracts of flowers, fruits and seeds of Hypericum amblysepalum. Materials and Methods: Antioxidant properties including free radical scavenging activity and reducing power, and amounts of total phenolic compounds were evaluated using different tests. Protocatechuic, catechin, caffeic acid, syringic acid, p-coumaric acid and o-coumaric concentrations in extracts were determined by HPLC. Cytotoxic effects were determined using the MTT test with human cervix cancer (HeLa) and rat kidney epithelium cell (NRK-52E) lines. Acetyl and butyrylcholinesterase inhibitory activities were measured by by Ellman method. Results: Total phenolic content of H. amblysepalum seeds was found to be higher than in fruit and flower extracts. DPPH free radical scavenging activity of the obtained extracts gave satisfactory results versus butylated hydroxyanisole and butylated hydroxytoluene as controls. Reducing power activity was linearly proportional to the studied concentration range: 10-500 µg/mL LC50 values for H. amblysepalum seeds were 11.7 and 2.86 respectively for HeLa and NRK-52E cell lines. Butyryl-cholinesterase inhibitory activity was 76.9 ± 0.41 for seed extract and higher than with other extracts. Conclusions: The present results suggested that H. amblysepalum could be a potential candidate anti-cancer drug for the treatment of human cervical cancer, and good source of natural antioxidants.

Currently, energy resources are rapidly consumed. Therefore, scientists and engineers study the effective use of energy. In the present study, a thermodynamic and exergoeconomic analysis was performed in a thermal power plant in Turkey. The study involved determining the thermodynamic properties of 27 node points in a thermal power plant unit, and this was followed by calculating energy and exergy values of every node. Mean exergy costs were calculated by establishing energy and exergy balances of the equipment with respect to the calculated results. Subsequently, lost and damaged energies and exergies were calculated, and exergoeconomic factors were determined. The equipments were compared with each other on a graph based on the obtained results. The maximum rate of exergy loss and cost of exergy destruction corresponded to 79.5% and 886,66 $/h, respectively. The maximum exergy losses in a thermal power plant occurred in the boiler, turbine groups, condenser, heating group, pumps, and auxiliary groups. The highest and second highest law efficiencies of the studied thermal power plant corresponded to 32.3% and 28.5%, respectively. The study also involved presenting suggestions for improvement. Additionally, exergoeconomic analyses were conducted while considering the power plants' investment and equipment maintenance costs. It is expected that the calculation method and the obtained results can be applied to other thermal power plants.

This work deals with exact soliton solutions of the nonlinear long-short wave interaction system, utilizing two analytical methods. The system of coupled long-short wave interaction equations is studied by two analytical methods, namely, the generalized tan (phi/2)-expansion method and He's semi-inverse variational method, based upon the integration tools. Moreover, in this paper, we generalize two aforementioned methods which give new soliton wave solutions. Abundant exact traveling wave solutions including solitons, kink, periodic and rational solutions have been found. These solutions might play an important role in engineering and physics fields. By using these methods, exact solutions including the hyperbolic function solution, traveling wave solution, soliton solution, rational function solution, and periodic wave solution of this equation have been obtained. In addition, by using Matlab, some graphical simulations were done to see the behavior of these solutions. (C) 2019 The Authors. Published by IASE.

Assessing the Prognostic Value of Halp Score in Peripheral Artery Disease: Correlation With Lesion Severity and Long-Term Mortality
(Sage Publications Ltd, 2025) Evsen, Ali; Aktan, Adem; Kilic, Raif; Yalcin, Abdulaziz; Ozbek, Mehmet; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Introduction Peripheral artery disease (PAD) poses a growing clinical challenge due to an aging population, despite advances in treatment methods. Various scoring systems have emerged to predict high-risk patients, including the HALP (hemoglobin, albumin, lymphocyte, and platelet) score, known for predicting prognosis in cancers and stroke. This study assesses the HALP score's relation to lesion severity and long-term mortality in PAD patients. Methods We retrospectively analyzed 305 symptomatic PAD patients undergoing endovascular intervention. The following formula was used to calculate the HALP score: hemoglobin (g/L) x albumin (g/L) x lymphocyte count (/L) / platelet count (/L). Lesion severity was classified by TASC-II: TASC AB and TASC CD. Mortality data were obtained from hospital and social security records. Results The study involved 305 patients (mean age 64.4 +/- 11.8 years; 72.1% male), divided into survivors (208) and non-survivors (97). ROC analysis identified HALP score as the strongest predictor of long-term mortality (AUC: 0.736; 95% CI: 0.679-0.793; p < .001). HALP score (HR, 0.087; 95% CI, 0.025-1.300; p < .001), age (p < .001), DM (p = .007), and CRP (p = .013) independently predicted mortality. Kaplan-Meier analysis showed higher HALP scores linked to lower long-term mortality (Log-rank: 20.102, p < .001), with an average follow-up of 48 +/- 18 months. Conclusion The HALP score emerged as a robust predictor of PAD prognosis, surpassing individual components and other parameters. Lower HALP scores correlated with more severe lesions and reduced life expectancy.

Understanding the genetic diversity and population structure of bread wheat germplasm is essential for effective breeding and conservation strategies. This study evaluated 96 bread wheat genotypes from Turkiye-including advanced lines, commercial cultivars, and landraces-using Start Codon Targeted (SCoT) and inter-Primer Binding Site (iPBS) retrotransposon markers. Six SCoT and four iPBS primers generated 81.32% and 75.59% polymorphic bands, respectively, producing clear and reproducible profiles. The average polymorphism information content was 0.19 for both marker systems, with resolving power values of 3.13 (SCoT) and 2.35 (iPBS). Unweighted pair group method with arithmetic mean (UPGMA) cluster analysis grouped the genotypes into two major clusters with 41% overall similarity. Principal coordinate analysis (PCoA) clearly illustrated the genetic differentiation among the genotypes. Analysis of molecular variance (AMOVA) revealed that 69% of genetic variation was distributed within populations. Pathogenicity assays revealed differential disease responses among 21 genotypes to Fusarium culmorum isolate, with the cultivar Empire exhibiting moderate resistance. SCoT and iPBS markers effectively revealed genetic variation and supported the exploitation of promising genotypes for resistance breeding. The identification of genetically distinct and moderately resistant genotypes underscores the potential of Turkish wheat germplasm to support future breeding efforts.
Attitudes of Health Sciences Students in Turkey Towards Individuals With Different Sexual Orientations
(Womens Health & Action Research Centre, 2025) Deger, Vasfiye B.; Kacan, Havva; 09.01. Department of Nursing / Hemşirelik Bölümü; 9. Faculty of Health Sciences / Sağlık Bilimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Study was planned in a descriptive design to examine how the empathic tendencies of students in the Faculty of Health Sciences affect their attitudes toward individuals who have different sexual orientations and was conducted with seven hundred and six students. The data collected online using the Student Information Form, Empathic Tendency Scale (ETS) and Attitudes Toward Lesbian and Gay Men Scale (ATLGS). Participants' mean scores were 62.98 +/- 18.79 on the ESS and 29.02 +/- 10.75 on the ATLGS. When the correlation between ETS and ATLGS scores was analyzed, a positive and moderate (p<0.05) correlation (r = 0.62) was found between ETS and ATLGS scores. These scores were moderate and the correlation between ETS and ATLGS scores was significant (F=438.585; p<0.05). Empathic disposition explained 38.3% of the total change in ATLGS level (R2=0.383) and increased ATLGS level (B=0.620). It was found that as students' empathic skills improved, their homophobic attitudes decreased.
