(MC) extract on a high fat diet (HFD)-induced testicular injury in a rat model were investigated using histological and biochemical methods. Wistar albino rats were divided into three groups: a standard diet control group; a HFD group; and an HFD+MC group. The HFD and HFD+MC groups were fed with a HFD for 16 weeks. MC extract (100 mg/kg) was given orally five days a week to the rats in the HFD+MC group during the last four weeks of the experiment. Leptin, triglyceride, high-density lipoproteins, cholesterol, estrogen, testosterone, LH and FSH were analyzed in blood serum. Sperm parameters were evaluated from the epididymis. Testicular morphology, proliferative, apoptotic and NADPH oxidase-2 (NOX2)-positive cells were evaluated histologically. Testicular oxidative stress parameters were analyzed biochemically. In the HFD group, lipid and hormone profiles were changed, abnormal spermatozoa, degenerated seminiferous tubules with apoptotic and NOX2-positive cells were increased in number, and sperm motility and germinal proliferative cells decreased compared to the control group. Moreover, testicular malondialdehyde, 8-hydroxy-2-deoxyguanosine and myeloperoxidase levels increased, whereas glutathione and superoxide dismutase levels decreased in the HFD group compared to the control group. All these histological and biochemical features were ameliorated by MC treatment of HFD-fed rats. In conclusion, HFD caused alterations in sperm parameters and testicular morphology by increasing oxidative damage and apoptosis. MC extract may have potential protective effects by inhibiting oxidative damage.Marmara University Scientific Research Project Committee [SAG-C-YLP-131217-0656]The work was supported by the Marmara University Scientific Research Project Committee [SAG-C-YLP-131217-0656].Science Citation Index Expande

No full textTas Soylu, Gulsenay/0000-0002-8153-4316; BAYSAN ARABACI, Leyla/0000-0002-0314-6350; Dikec, Gul/0000-0002-7593-4014This study aimed to evaluate substance use and comorbid mental disorders in delinquent adolescents presenting to a child and adolescent psychiatry outpatient clinic. This study included 47 adolescents aged 15-18 years and had a history of delinquency. Data were collected using the Addiction Profile Index Adolescent Form (API-A) and an information form. Results indicated that the adolescents' mean age is 16.11 +/- 1.05 years, 78.7% had committed crimes against property and 34.0% against the person, and 34.0% were also victims of crime. Mean API-A total scores indicated that their level of substance use was low. In addition, mean API-A total scores showed significant differences according to the adolescents' migration status, age, economic status, school attendance, mental disorder diagnosis, duration of mental disorder, and type of offense (p < 0.05). The benefit provided by timely and appropriate psychosocial interventions may have a key role in solving this problem for adolescents and improving their future as adults.Science Citation Index Expanded - Social Science Citation Inde

No full textPolat Ilguz, Basak/0000-0003-1072-4128; Ovacik, Ugur/0000-0001-6137-3466; Gungor, Feray/0000-0003-2814-3276; ANALAY, YILDIZ/0000-0002-8141-6977Introduction Many assessment methods are used in physiotherapy to analyze the fitness level and injury risk in athletes, and to determine the general health status and the effectiveness of the treatment applied in patients. Considering the need for telehealth use, it is essential to determine the usability of tests performed as tele-assessment. This study aimed to examine the intra-rater reliability, validity, and feasibility of the tele-assessment version of core strength and endurance and functional capacity assessments in healthy individuals. Methods "Curl-up," "Modified Push-up," "Plank," and "Lateral Bridge" tests were used for core strength and endurance performance assessment, and "Timed Up and Go," "30 second Sit to Stand," and "Functional Reach Test" tests were used for functional capacity assessment in healthy individuals. Participants were evaluated first by tele-assessment, then one hour later on the same day, all assessments were repeated face-to-face procedures by the researchers thus the validity of the tele-assessment method was determined. All tests were applied as tele-assessment one week later to determine the intra-rater reliability of the tele-assessment method. The system usability scale was applied to evaluate the usability of our tele-assessment method. Results Eighty healthy people were enrolled. Intraclass correlation coefficients ranged between 0.91 and 0.97 for core performance tests and between 0.95 and 0.97 for functional tests. All tele-assessment versions of the core performance and functional tests were highly correlated with the face-to-face versions. Discussion Core strength-endurance and functional tests performed via tele-assessment were reliable, valid, and feasible for practically measuring the performance of healthy young adults. This study supports the tele-assessment versions of these tests.Science Citation Index Expande

Materials and Methods: Male Wistar albino rats were divided into control (CNT), high-fat diet (HFD) and HFD+APO groups. HFD and HFD+APO groups were fed HFD for sixteen weeks. APO (25 mg/kg) was administered to the HFD+APO group for the last four weeks. The effects of APO on: AS-related metabolic parameters (triglyceride, total cholesterol, high-density lipoprotein-cholesterol, insulin and leptin), oxidative stress (OS), [ malondialdehyde, glutathione, nicotinamide adenine dinucleotide phosphate (NADPH)oxidase-2, oxidised-low-density lipoprotein (ox-LDL) and 8-hydroxy-2-deoxyguanosine], low-density lipoprotein and ox-LDL uptake potential (activin receptor-like kinase-1 and lectin-like oxidized low-density lipoprotein receptor-1, respectively), tissue inflammation inducible-nitric oxide synthase, nitric oxide), programmed cell death (terminal deoxynucleotidyl-transferase-dUTP-nick-end (alpha-smooth muscle actin), histology and ultrastructure of thoracic aorta were evaluated. Results: In obesity, APO had an ameliorative effect on metabolic parameters, OS, inflammation, ED, programmed cell death and oxLDL uptake potential, but not on foam cell formation and LDL uptake potential. Conclusion: Apocynin may improve ED and AS in obesity by suppressing OS-linked factors involved in the early stage of AS.Marmara University Scientific Research Project Commission [SAG-C-DRP-080.519.0182]Funding: This study was financially supported by Marmara University Scientific Research Project Commission (SAG-C-DRP-080.519.0182) .Emerging Sources Citation Inde
Synthesis and Anti-Hcv Activity of Novel 5-Arylmethylene Derivatives Via Suppression of Ns5b Polymerase and Cox-2
No full textHepatitis C (HCV) is a viral infection that leads to forms of acute and chronic liver disease, including cirrhosis (scarring of the liver) and liver cancer. The World Health Organization (WHO) estimated in 2019 that approximately 290,000 people died from hepatitis C (mostly from cirrhosis and hepatocellular carcinoma). Directacting antiviral drugs (DAAs) can cure more than 95% of individuals with hepatitis C infection, while research on the discovery of new antiviral agents is still ongoing. The Hepatitis C virus (HCV) can cause various biochemical changes in liver cells, and some of these changes are associated with the COX-2 enzyme. The identification of its role in promoting growth in liver cells as well as its involvement in various cancer types, including hepatocellular carcinoma, has made COX-2 an important target in the development of new agents effective against HCV. In this study, thirty-six new 5-arylmethylene-2-imino-1,3-thiazolidin-4-one derivatives (5a-s, 6a-s) were synthesized through Knoevenagel condensation of 2-[(4-substitutedpyridin-2-yl)imino]-1,3thiazolidin-4-one derivatives with various aldehydes. Structures of the synthesized compounds were elucidated by the use of spectral and chromatographic techniques, besides elemental analyses. Four compounds were selected for further studies as they were found to suppress the NS5B protein with anti-HCV activity using the Western Blotting method. The selected compounds 5o, 6m, 6r, and 6s inhibited HCV with EC50 values of 8.0 +/- 0.2 mu M, 13.9 +/- 0.45, 9.2 +/- 0.2 mu M, and 12.1 +/- 0.1 mu M, respectively. It was determined that these compounds reduced HCV-induced COX-2 promoter activity in Ava5 cells compared to Huh7 cells. The antiviral effects of the compounds were also investigated on DENV, closely related to HCV due to sharing certain biological, structural, and mechanical properties throughout their life cycles. However, no significant effect was observed in the preliminary screening study, indicating the compounds' specificity for HCV. Considering the relationship between HCV, DENV, and COX-2, the compounds' COX-1 and COX-2 enzyme inhibition potentials were investigated both in vitro and in silico. Compounds 6d, 6e, 6f, and 6m, which exhibited high selective COX-2 inhibition, were discussed for their interactions with the active site. Our study revealed that our target compounds suppressed COX-2 both at the protein level and through enzyme inhibition, thus providing promising findings for the discovery of new anti-HCV effective COX-2 inhibitors.Scientific Research Project Commision of Marmara University [SAG-C-DRP-050614-0227]; Ministry of Science and Technology of Taiwan [MOST111-2311-B-110-001]; Scientific and Technological Research Council of Turkey (TUBITAK) [2211-C]This study was supported by the Scientific Research Project Commision of Marmara University (Project number: SAG-C-DRP-050614-0227) and the Ministry of Science and Technology of Taiwan (under grant numbers MOST111-2311-B-110-001).

Examining the Sensory Processing Skills and Occupational Performance of People With Multiple Sclerosis
No full textAydoner Bektas, Selen/0000-0002-0663-1802This study aimed to compare sensory processing skills and occupational performance between participants with multiple sclerosis and healthy controls. Eighty participants were enrolled in this study, 40 with multiple sclerosis and 40 with healthy controls. Participants were between 18 and 65 years of age and asked to complete the Adult Sensory Profile, and Canadian Occupational Performance Measure. The findings of the study revealed that participants with multiple sclerosis had a lower ability to register sensory input, a higher sensory sensitivity, and avoidance, as well as lower levels of performance and satisfaction in their daily occupations, compared to the healthy controls (p < 0.05). People with multiple sclerosis often experience difficulties with sensory processing and occupational performance in daily life. More research and practice are needed on the role of sensory processing and occupational performance in daily life in people with multiple sclerosis.Emerging Sources Citation Inde
Disaster Risk Perception and Sustainable Earthquake Awareness Among Public and Private University Nursing Students
No full textNirgiz, Cansu/0000-0001-9595-2853; EROGLU, NERMIN/0000-0003-4780-3049Background: This research was conducted in descriptive type to determine the disaster risk perception and sustainable earthquake awareness of nursing students studying at public and private universities. Methods: The study sample consisted of 400 nursing students studying at one public and one private university. The research was conducted between April and May 2023. The data were collected using a Sociodemographic Form, University Students Disaster Risk Perception Scale (USDRPS), and Sustainable Earthquake Awareness Scale (SEAS). Data were collected online using a questionnaire created on Google Forms. Analyses included frequency, percentage, mean, standard deviation values, independent groups t-test, post-hoc Tukey test, LSD, and ANOVA test. Results: Of the students, 61.8% had a disaster experience, 17.4% had lost a relative in the disaster, and 76.8% did not consider themselves prepared for a possible disaster. In the study, the exposure sub-dimension score of the disaster risk perception scale was found to be higher in students who had disaster experience than in those who did not (p = 0.032). Nursing students from the private university had higher sustainable earthquake awareness scores than those studying at the state university (p = 0.001). The mean scores of female students on the earthquake preparedness and preparation application sub-dimensions showed a significant difference compared to the scores of male students (p = 0.016). In the study, sustainable earthquake awareness total and earthquake preparedness sub-dimension scores were higher in second-year nursing students than in students of other years (p = 0.042; 0.015). Those who had received disaster training had low scores on the uncontrollable sub-dimension of the disaster risk perception scale, and high scores on the total SEAS and earthquake-structure relationship, earthquake preparedness, and earthquake preparation application sub-dimensions (p < 0.05). Conclusions: In the study, three out of four students did not find themselves prepared for disasters. Those who had disaster experience had higher disaster risk perceptions. Students who had received disaster-related training had more positive earthquake preparedness, earthquake-structure relationship, and earthquake preparation applications than those who had not. Students who were female and were in the second year had higher earthquake awareness. Studies can be carried out to inform people about the pre-disaster and preparation stages to raise awareness about disasters at universities. Education on disaster management can be integrated into courses from the first years of university.Science Citation Index Expanded - Social Science Citation Inde
Improving Yolo Detection Performance of Autonomous Vehicles in Adverse Weather Conditions Using Metaheuristic Algorithms
No full textozcan, ibrahim/0000-0001-9471-5119; ALTUN, Prof. Dr. Yusuf/0000-0002-2099-0959; PARLAK (PhD), CEVAHIR/0000-0002-5500-7379Despite the rapid advances in deep learning (DL) for object detection, existing techniques still face several challenges. In particular, object detection in adverse weather conditions (AWCs) requires complex and computationally costly models to achieve high accuracy rates. Furthermore, the generalization capabilities of these methods struggle to show consistent performance under different conditions. This work focuses on improving object detection using You Only Look Once (YOLO) versions 5, 7, and 9 in AWCs for autonomous vehicles. Although the default values of the hyperparameters are successful for images without AWCs, there is a need to find the optimum values of the hyperparameters in AWCs. Given the many numbers and wide range of hyperparameters, determining them through trial and error is particularly challenging. In this study, the Gray Wolf Optimizer (GWO), Artificial Rabbit Optimizer (ARO), and Chimpanzee Leader Selection Optimization (CLEO) are independently applied to optimize the hyperparameters of YOLOv5, YOLOv7, and YOLOv9. The results show that the preferred method significantly improves the algorithms' performances for object detection. The overall performance of the YOLO models on the object detection for AWC task increased by 6.146%, by 6.277% for YOLOv7 + CLEO, and by 6.764% for YOLOv9 + GWO.Duzce University Scientific Research Projects Coordination Office [BAP-2020.06.01.1060]This research was funded by Duzce University Scientific Research Projects Coordination Office with the Scientific Research Project grant number BAP-2020.06.01.1060.Science Citation Index Expande
