Book Part The Importance of Corporate Social Responsibility Studies in Textile Companies and a Case Study: Ozanteks Tekstil Company’s Corporate Social Responsibility Studies(Springer International Publishing, 2024) Elibüyük, Sultan Aras; Avinc, Ozan; Çörekcioğlu, Mustafa; Yildirim, Fatma Filiz; Öztürk, Serap; Güngör, AşkınerArticle Beneficial Effects of Taurine on 2,3,7,8-Tetrachlorodibenzo-p-Dioxin-Induced Oxidative and Histopathological Damage in the Heart Tissue of Rats(SAGE Publications Inc, 2026-03-23) Çiftçi, Osman; Kaplan, Münevver Nazlıcan; Başak Türkmen, Neşe; Çetin, Aslı; Çiftçi, Bedriye; Ayhan, İdrisThis study investigated the protective effects of taurine against 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-induced cardiotoxic damage in rats. Adult male Wistar rats (250-300 g) were randomly assigned to four groups (n = 8 per group): Control, TCDD, TAU, and TCDD + TAU. TCDD (2 mu g/kg/week) and/or taurine (200 mg/kg/day) were administered via gavage for 30 days. Following the experimental period, heart tissue samples were collected for analysis. Oxidative stress parameters, including thiobarbituric acid reactive substances (TBARS), superoxide dismutase (SOD) activity, and glutathione (GSH) levels, were assessed using biochemical methods. Histopathological and immunohistochemical evaluations of cardiac tissue were also performed. The TCDD group showed significantly increased TBARS levels (p < 0.05) and decreased SOD activity and GSH levels (p < 0.001) compared with the Control group. In contrast, taurine co-administration significantly increased SOD activity and GSH levels while reducing TBARS levels relative to the TCDD group. Moreover, TCDD exposure induced marked histopathological alterations in heart tissue, whereas taurine co-administration attenuated these structural alterations. Immunohistochemical findings indicated that taurine attenuated TCDD-induced apoptosis by reducing caspase-3 activation. Overall, taurine effectively mitigated TCDD-induced oxidative stress, histopathological damage, and apoptotic signaling in cardiac tissue, suggesting that taurine co-administration may exert protective effects against TCDD-induced cardiotoxicity.Article The Trace Element Concentrations in Tissues From the Loggerhead Sea Turtle (Caretta Caretta) From Different Life Stages in Türkiye(Univ. Oradea Publ. House, 2025) Sozbilen, Dogan; Baskale, Eyup; Hol, Aysen; Kaska, Arzu; Divrikli, Umit; Elci, Latif; Kaska, YakupSea turtles can bioaccumulate essential and nonessential trace elements, making them useful bioindicators of the marine ecosystem. We analyzed the 11 trace element concentrations in kidney, liver, and muscle samples (n=175) of stranded loggerhead sea turtles, Caretta caretta (n=70). Our results for Fe, Cu, Zn, and Mn were lower, but Pb, Ni, and Cd levels were higher than those reported in the literature. Given the high levels of loggerhead turtles in specific foraging areas, long-term, concurrent trace element monitoring studies on a larger geographic scale are necessary to understand trace element exposure levels in loggerhead turtle tissues. Conservation of long-lived animals, such as sea turtles, depends on the sustainable monitoring of the pollutants in their environment. Although metal levels were lower than those reported in the literature, we view the Mediterranean Sea as a vast lake into which the 20 countries surrounding it discharge contaminants, and we recommend continuing temporal and spatial monitoring of the impact of pollutants on sea turtles.Article Part 2: Cationization of Cotton Bedsheet Fabrics by Pad-Batch Method(E.u. Printing and Publishing House, 2025) Yildirim, Fatma Filiz; Elibuyuk, Sultan Aras; Avinc, Ozan; Koyuncuoglu, Mehmet Ulan; Yumru, Saban; Aras Elibüyük, SultanCotton is the most widely used fibre in manufacturing, which, being negatively charged, requires various electrolytes to be dyed with negative dyestuffs. These electrolytes cause a large environmental waste water load and unfortunately many of them are released into the environment after waste water treatment. It seems possible to overcome this problem by cationization cotton. This research paper is a two-part study. In the first part of the paper has two sections. The initial section of this paper, 100% cotton terry towel fabrics were subjected to cationization procedures during and after the bleaching process in a laboratory setting, utilizing six distinct commercial cationization agents by using exhaustion method. The cationized cotton terry towel fabrics were then subjected to dyeing procedures: salt-free reactive dyeing, conventional reactive dyeing and acid dyeing. The CIELAB values, rubbing and washing fastness, and colour strength (K/S) of the fabrics were then compared. Subsequently, a decision analysis study (analytical hierarchical process, AHP) was conducted to identify the optimal cationization agent and processes for big commercial-scale applications. The criteria included color strength, color fastness, and cationic agent cost. In light of the findings of the AHP studies, CA1 coded cationization agent (based on polyammonium compounds) was identified as the optimal cationic agent for utilization in commercial dyeing, the specifics of which will be outlined in the subsequent paper. Moreover, the findings indicated that cationization should be carried out after bleaching. The second section of the paper presents the results of big commercial scale cationization, reactive and acid dyeing's carried out using the selected cationization agent and exhaustion processes. The influence of these processes on the properties of fastness (perspiration, wash, and water fastness) and physical characteristics (tensile strength and water absorption) of cotton terry towel fabrics was evaluated by statistical comparison. The chemical oxygen demand, ammonium nitrogen, total chemical, energy, and water consumption of the commercially available dyes were also compared to assess their environmental impact. The second part of the study examined the cationization of cotton fabrics used for bed sheets - an important home textile product - using the pad-batch method, followed by dyeing. The weaving of fabrics generally occurs in an open-width configuration, wherein the fabric is spread out during the weaving process. This characteristic renders pad-batch dyeing processes particularly well-suited for the treatment of woven fabrics. It may be concluded that rope dyeing is not a common practice when it comes to woven fabrics. Rope dyeing has been observed to result in the formation of crease marks and uneven dyeing on woven fabrics. The first part of the article provides a detailed exposition of the cationization and dyeing of towel fabrics through the utilization of the rope dyeing method (exhaustion). The second part elucidates the cationization and dyeing of bed sheet fabrics employing the open-width dyeing method (pad-batch). The CIELAB values, rubbing and washing fastness, and colour fastness (K/S) values of the cotton bed sheet fabrics were statistically compared. The statistical analysis indicated that cationic agents and dyeing types exerted a statistically significant effect on K/S. In a similar manner, the quantity of cationic agent had a significant effect on the K/S values. Furthermore, the batching time subsequent to the dyeing process resulted in significant important effect in the K/S values of the fabrics. The factor groups that ensure the colour strength value remains at its optimal (maximum) level are, in order: cationic agent; CA1 coded cationization agent (based on polyamine compounds), cationic agent amount; 5g/l and a waiting (batching) time of 8 hours. In view of the findings, the following conclusions can be drawn with regard to reactive dyeing by pad-batch method: the optimum values in terms of environmental aspects and dyeing can be accepted as 5 g/l of CA1 cationic agent and 8 hours batching.Article Early Childhood Teachers' Reflections on 'The Creativity in Teacher's Nature' Professional Development Program(Springer, 2025-12-04) Bayraktaroglu, Eda; Kalburan, Nilgun Cevher; Cevher Kalburan, NilgünThis qualitative case study examined the impact of a six-week, 13-session professional development program, Creativity in Teacher's Nature (CTN), on early childhood teachers' creativity-related practices. Participants were ten preschool teachers. Data sources included demographic and evaluation forms, a researcher's reflective journal, documents (e.g., worksheets, nature observation forms), photographs, and short videos recorded in each session. Thematic content analysis was conducted, guided by Urban's creativity model. Findings indicated that teachers reconstructed their pedagogical frameworks by integrating nature-based experiences into planning, environment design, open-ended materials, play, art, and communication. Teachers also reported gains in professional competence, ecological awareness, and motivation. Furthermore, they described shifts toward child-centered approaches and increased family involvement. The study suggests that nature-based professional development can strengthen teachers' creative dispositions and classroom practices. Limitations include the small sample and short duration; future longitudinal studies are recommended.Article Gall Wasp (Cynipoidea: Cynipidae) Fauna of Aydın Province (Türkiye)(Magnolia Press, 2025-09-23) Tataroglu, Musa; Katilmis, YusufIn order to document the gall wasp fauna (Hymenoptera: Cynipidae) of Ayd & imath;n province, extensive field studies were conducted between 2023 and 2025.

The ACE inhibitory effect of all WSEs increased over time, with the highest activity observed at 71.36 % on day 90 in conventional white (CW) cheeses made with calf rennet. The WSEs from CW cheeses produced with microbial rennet demonstrated the broadest antimicrobial spectrum on day 30 of storage. The highest inhibition zone, however, was detected against S. typhi using WSEs obtained from 30-day-old UF cheeses made with microbial rennet. Peptides associated with WSEs displaying high biological activity were identified using LC-ESI-QTOF-MS, revealing the presence of peptides with varying sequences demonstrating antioxidant, antimicrobial, and ACE inhibitory activities. Peptides YLGYLEQLLR, FFVAPFPEVFGK, TKVIPYVR, VIPYVRYL, TKVIPYVRYL, and FALPQYLK with different biological activities were identified in the 90th day of CW cheeses produced using microbial rennet. © 2025 Elsevier B.V., All rights reserved.Correction A Phenological Shift to Save the Boys?

The current study aims to reveal the general status of social media addiction research in students published in journals indexed in Scopus. In the selection of the studies, attention was paid to the fact that they were related to social media addiction in students, that they were in the article category, that they were in English and Turkish languages, and that they were open access. Publications in open-access journals written in Turkish and English languages were analyzed from 1032 documents obtained from the identification made using the Scopus database. In this way, 849 articles were included in the analysis. Publications are concentrated in the "International Journal of Environmental Research and Public Health", with "Institute of Psychology, Elte" playing a central role in the analysis of co-authors for inter-institutional collaboration. While "Demetrovics, Zsolt" stands out in co-authorship, the most cited institution is "Institute of Psychology, Elte E & ouml;tv & ouml;s Lor & aacute;nd University, Budapest, Hungary" and the most cited author is Griffiths M. D.. Demetrovics, Zsolt are at the center of the cluster formed as a result of the bibliometric link analysis between the authors. The most frequently used keywords are social media addiction, adolescents, problematic social media use, social media and academic performance. It can be said that although the number of publications made in T & uuml;rkiye is at the forefront, the number of citations is low, which requires an increase in institutional support for research.Article Citation - WoS: 2Citation - Scopus: 1Tireless Travellers: Sea Turtles Swim Continuously During Homing Movements(Academic Press Ltd- Elsevier Science Ltd, 2025-06) Luschi, Paolo; Cerritelli, Giulia; Biondi, Alessia; Costanzi, Riccardo; Kaska, Yakup; Sozbilen, Dogan; Hays, Graeme C.; Casale, PaoloWhile rest and sleep are crucial to animals, our understanding of whether and how long-distance migrants rest has been thwarted by the inability to relay high-resolution data from multichannel loggers via satellite. We overcame these obstacles for an iconic long-distance migrator by equipping five loggerhead sea turtles, Caretta caretta, with satellite tags and data loggers providing depth and three-dimensional acceleration measurements. Turtles were translocated to open-sea locations and induced to complete oceanic journeys of 10 km to return to their nesting beach, performing active, oriented movements. Across a total of >600 h of high-resolution data, we observed (1) a constant flipper frequency indicating that turtles never ceased movement, (2) intense subsurface swimming for about half the time and (3) deeper, less active dives up to 80 m, which were made day and night and more frequently in offshore waters. Flipper beat amplitude was much smaller in deep dives; hence, the estimated energy expenditure was lower on deep dives compared with subsurface swimming. These findings suggest that turtles, which can complete migrations of >2000 km, alternate between phases of intense near-surface swimming and periods of lower activity at depth, without fully resting during extended homing journeys.
