CRYOPRESERVATION AND ASSESSMENT OF HONAMLI AND HAIR BUCK SEMEN USING RESVERATROL
No full textBACKGROUND: Resveratrol (Res) (3,5,4 '-trihydroxystilbene) is a natural polyphenol that exhibits important biological activities. OBJECTIVE: To assess the effects of resveratrol (Res) on freeze-thawed survival of semen from Honamli and Hair Bucks. MATERIALS AND METHODS: Six bucks, aged 2-3 years (three from each breed), were included in the study. Semen was collected from each breed and mixed separately after removing seminal plasma. The mixed semen was diluted with different Res concentrations (0 mu M as control, 25 mu M, 50 mu M, 100 mu M, 500 mu M, and 1 mM) in Tris diluent and subjected to cryopreservation in liquid nitrogen vapor and frozen. After thawing, the samples were evaluated for motility and some spermatologic quality parameters by flow cytometry. RESULTS: Data were analyzed separately for Honamli and Hair breeds. The results showed that the Res 1 mM group had the lowest motility in all assessments (P0.05). In terms of apoptosis, Hair bucks exhibited a statistically significant difference in late apoptotic parameters, with the control showing the highest values (P<0.05). The Res 25 mu M group (similar to the control group) showed lower mitochondrial oxidative stress than the Res 1 mM group (P<0.05). CONCLUSION: Res at a dose of 1 mM did not protect most sperm functional and biochemical parameters except for apoptosis and performed worse than the control group. When all parameters are evaluated collectively, concentrations lower than 1 mM should be used for freezing Honamli and Hair Buck semen with resveratrol.Burdur Mehmet Akif Ersoy University Scientific Research Projects Coordination [0726-MP-21/2017K12-41003]This research was supported by Burdur Mehmet Akif Ersoy University Scientific Research Projects Coordination, Project No. 0726-MP-21/2017K12-41003

Tourism's hidden gem: Niche tourism unveiled through resident insights
No full textNiche tourism has emerged as a pivotal strategy in mitigating tourism's negative environmental, economic and sociocultural impacts. Previous studies highlight the importance of niche tourism as a counterbalance to mass tourism, fostering sustainable tourism development. This chapter, utilizing the stimulus-organism-response (SOR) theory, investigates how residents' attachment to their community and perceptions of mass tourism influence their attitudes towards niche tourism development. Additionally, it examines how these attitudes predict their support for niche tourism and expectations of its potential benefits. Data was collected through quantitative research conducted in Manavgat, Türkiye, a region characterized by intense mass tourism development. Results indicated that strong community ties and negative perceptions of mass tourism significantly enhanced favourable attitudes towards niche tourism. Furthermore, residents' attitudes towards niche tourism development significantly predicted their support for niche tourism and their expectations of its benefits. The chapter highlights the importance of involving residents in sustainable tourism practices, which can lessen the negative effects of mass tourism and support sustainable niche tourism development. These findings provide valuable guidance for policy makers and practitioners in crafting sustainable tourism strategies that meet the needs and expectations of local communities. © CAB International 2025.

A total of 80 patients with asymptomatic devital single root and single canal mandibular premolar teeth participated in the study. The patients were randomly divided into four groups, and each group received a different final irrigation and disinfection procedure: conventional needle irrigation (CNI), sonic irrigation (SI), passive ultrasonic irrigation (PUI), and KTP laser disinfection. Mandibular anesthesia was administered, and access cavity was prepared in tooth isolated with a rubber dam. The working length was determined and root canal preparation was performed using the One Curve rotary file system. During preparation, irrigation was performed with a total of 6 ml of 2.5% NaOCl solution using a 31G side-vented irrigation needle at a rate of 2 ml/20 sec. Following this, the final irrigation procedure was performed according to the pre-determined activation and disinfection groups. Final irrigation consisted of three irrigation cycles, each applied for 20-sec, with a total of 6 ml of 2.5% NaOCl solution. After each irrigation cycle, a 20-sec resting time was applied in the CNI and KTP laser groups and a 20-sec activation was performed in the SI and PUI groups. Subsequently, irrigation was performed with 2 ml of 17% EDTA for 1 minute, followed by a 1-minute resting/activation. 2 ml of distilled water was used as the final irrigation solution. In the KTP laser group, KTP laser was applied to the root canal dried with sterile paper points. The root canal was filled using the single-cone technique with gutta-percha and AH Plus sealer. Permanent resin composite restoration of the tooth was performed in the same session. To evaluate pain, patient was given a postoperative pain assessment form and were asked to mark the intensity of the pain at 6, 24, 48 and 72 hours, and on the 7th day on a VAS. A clinical follow-up and percussion evaluation were performed on the 7th day. The data were statistically analyzed using Shapiro-Wilk, variance analysis, Tukey test, Bonferroni, Kruskal-Wallis test, Mann-Whitney U test, Friedman test, Wilcoxon test, and Chi-square tests, and the significance level was defined as p0,05). In all groups, the highest postoperative pain scores were recorded at 6 hours. While age and gender did not significantly affect postoperative pain levels, patients with periapical lesions reported significantly less postoperative pain in the CNI group at the 6th hour, in the SI group at the 48th hour, and at the 48th hour when all patients were evaluated (p<0.05). Within the limitations of this study, root canal disinfection procedures performed did not show significant differences in postoperative pain

Predictive role of non-viral leukocyte parameters in tracking the development and progression of Crimean-Congo hemorrhagic fever
No full textThis study aims to investigate the extended leukocyte parameters, known as cell population data (CPD), in Crimean-Congo hemorrhagic fever (CCHF) and to evaluate their diagnostic performance in assessing mortality risk and intensive care unit (ICU) admission requirements. The study included a total of 260 participants, comprising 200 individuals diagnosed with CCHF and 60 healthy controls. CPD analyses were conducted using a Sysmex-XN 9000 complete blood count analyzer. Elevated levels of immature granulocyte (IG) percentage, neutrophil reactivity indices (Ne-X, Ne-Y), dispersion of neutrophil NE-SSC and NE-SFL signals (Ne-WX, Ne-WY), monocyte metabolic activity (Mo-X), and lymphocyte metabolic activity (Ly-X) were observed in CCHF patients compared to controls. Conversely, lymphocyte metabolic activity (Ly-Y) and monocyte fluorescence intensity (Mo-WY) were lower in patients than in controls. In discriminating mortality, IG#, IG%, Ne-WY, and Ly-Y exhibited higher AUC values than other CPDs. Additionally, for predicting ICU requirements, IG#, IG%, and Ne-WY demonstrated higher AUC values compared to other CPDs. IG, Ne-WY, and Ly-Y have the potential to serve as biomarkers for predicting mortality in CCHF. Furthermore, IG and Ne-WY may emerge as innovative and reliable biomarkers for identifying severe cases and predicting ICU admission requirements
Magnetic deep eutectic solvents for vortex-assisted liquid phase microextraction method for selective and green extraction of patulin from fruits and fruit juices
No full textIn this study, a vortex assisted magnetic deep eutectic solvent based liquid phase microextraction (VA-MDESLPME) technique was developed for the extraction of patulin prior to its determination by ultraviolet-visible spectrophotometry (UV-Vis). For this purpose, the use of a magnetic deep eutectic solvent (MDES) consisting of trihexyltetradecylphosphonium chloride, MnCl2, and octanoic acid (molar ratio 1:2:2) was tested to perform an efficient extraction. Important experimental parameters (MDES-3 vol, pH, vortex time, and ethanol volume) were optimized using Box-Behnken Design. Under optimum conditions (MDES-3 vol 560 mu L, pH 3.5, vortex time 300 s, and ethanol volume 300 mu L), the limits of detection for the model solution and matrix-matched solution were 0.06 ng mL- 1 and 0.37 ng mL- 1, and the calibration ranges were 0.2-400 ng mL- 1 and 1.2-300 ng mL- 1, respectively. Furthermore, the extraction recovery was calculated to be 96.3-97.4 % with a low relative standard deviation (2.1-2.5 %). The VA-MDES-LPME technique was successfully applied for the determination of patulin from fruit and juice samples with an enrichment factor between169 and 185.National Science Centre, Warsaw, Poland [UMO-2018/30/E/ST8/00642]Financial support from the National Science Centre, Warsaw, Poland - decision no.

Thermodynamic properties of a Gaussian quantum ring in the presence of a molecular ion
No full textIn this study, the findings of research conducted into the thermodynamic properties of a molecular complex ion in a 2D quantum ring characterized by Gaussian-type potentials are presented. The Schr & ouml;dinger equation for a singly ionized double donor complex was solved by a two-dimensional diagonalization method. The results obtained show that at the internuclear distance, where there is coupling between the Coulomb centers such that the electron is shared by both impurity atoms, the mean energy and entropy of the system are minimal. A further finding is that in the regime where the distance between impurity atoms is comparable to the inner radius of the quantum ring, the heat capacity of the system undergoes significant changes with temperature.Scientific and Technological Research Council of Turkiye (TUBITAK)Open access funding provided by the Scientific and Technological Research Council of Turkiye (TUBITAK)
