Kutlu, Banu; Çevik, Fatma; Çetindağ, Serdar
The primary considerations within aquatic ecosystems are water and sediment quality, rendering it imperative to assess their concentrations, pollution levels, origins, and ecological hazards. In this study, heavy metal concentrations in surface waters and sediments of the Pülümür Stream were investigated to assess the level, distribution, source of pollution and the associated human risks. Water and sediment samples from the river were collected monthly from February 2021 to January 2022 and examined using the Inductively Coupled Plasma Mass Spectrometry (ICP– MS) technique. Metal concentrations in the sediment followed a decreasing or derivative sequence of Fe > Al > Mn > Ni > Cr > Zn > Cu > Pb > As >Cd > Hg. The ecological indices of the stream water have low degrees of contamination by heavy metals. Igeo and EF showed that most of the sites are moderately to highly polluted due to Ni, and Cr, while PLI and PERI showed a progressive deterioration of the environment at site 9. Moreover, the modified hazard quotient (mHQ) indicates low ecological risk for Cu, Pb, Zn, Cd, Hg metals, while Ni, As and Cr reach high pollution at sediment sites. Pearson correlation analysis revealed that the presence of Zn, Cu, Pb, Hg, and Mn metals in the sediment analysis has a lithogenic source, and As, Ni, Cd, and Cr accumulate due to human activities, mainly domestic and agricultural irrigation wastes and mining wastes, all of which affect the aquatic environment. According to this study, more attention should be paid to the comprehensive monitoring of metals in the water and sediment for both aquatic biota and human risk of the Pülümür River.

Danışmaz, Harun; Adalı, Selim Ferruh; Şahin, Özgür
This study is concerned with the evaluation of a recently discovered Aramaic inscription and other archaeological remains found at Rabat Fortress (in Tunceli, Türkiye). The Hellenistic period Aramaic funerary text was composed in memory of a local lord from Sophene’s local political elite, with connections to the Orontid dynasty. This is the first known local Aramaic inscription from Sophene. The Aramaic inscription introduced in this study provides significant new information about the Hellenistic-period context for rock-cut stepped tunnels and single-roomed rock-cut tombs known across eastern Anatolia. The Rabat Fortress site provides corroborating evidence for the dating of the stepped tunnels that exhibit the same rock-cutting techniques in the same region to the Hellenistic and later periods in the rocky landscape. The inscription is rendered in a unique Sophene adaptation of the Middle Aramaic script extant on a corner block inside the Fortress. Its funerary context in rocky landscape and the inscription’s script and content indicate that the local elite at Rabat Fortress used Aramaic, and the notion of Orontid lineage to connect with the kingdom of Sophene’s central authority, which positioned itself between Hellenistic and Iranian traditions.

Çelikel, Baha Engin; Yılmaz, Coşkun; Demir, Alper; Sezer, Süreyya Yonca; Ceylan, Levent; Ceylan, Tülay; Tan, Çetin
Background: The effect of inspiratory muscle training on upper limbs One Rep Maximum (1RM) in professional natural bodybuilders is still unclear. Our aim of this study is to investigate the effects of a 6 weeks inspiratory muscle training on 1RM results. Methods: This study included 14 athletes, that had participated in international bodybuilding competitions. Each athlete had been training for minimum of 5 years and at least 5 h per week. The participants were randomly divided into two groups: inspiratory muscle training (IMT) and control (CON) groups. The IMT group and CON group consisted of seven subjects. While the control group continued with the normal training regime, the IMT group additionally performed inspiratory muscle training with the resistance setting of the PowerBreathe® Classic device set to 40% of the participant’s MIP. Prior to and during the 6-week training period, the bench press 1 RM, anthropometry, pulmonary function tests, and maximal inspiratory (MIP) and expiratory (MEP) pressure measurements were obtained. A nutrition protocol developed by a qualified dietician was implemented for each athlete. Results: The mean maximal strength of the respiratory muscle training group changed by 14.39%, whereas that of the control group changed by 9.43% (p = 0.012). The changes in the mean FVC (p = 0.000), FEV1 (p = 0.001), PEF (p = 0.064), MIP (p = 0.001), and maximal expiratory pressure (p = 0.017) were greater in the IMT group. The mean circumferences of the shoulder (p = 0.004), chest (p = 0.008), arm (p = 0.004), and neck (p = 0.003) improved more in the IMT group than in the CON group. A reduction in abdominal measurement was observed in the IMT group (p = 0.039), whereas no notable discrepancy was identified in body fat percentage (p = 0.295). Conclusion: In conclusion we identified that the addition of progressive loading inspiratory muscle training for competition preparation programs in professional natural bodybuilders will further improve their respiratory function, respiratory muscle strength, maximal strength, and muscle development. This research provides valuable insights into how IMT influences bodybuilding training outcomes, potentially guiding future interventions and program designs to better support strength development and body composition in bodybuilding training contexts.

Akti Aslan, Seda; Turgut, Yiğit Emrah; Aslan, Alper; Özyurt, Özcan
In this study, 3646 articles published in the Scopus database between 1975 and 2024 were analyzed to examine the main research themes, trends, and research gaps in the field of librarianship. Using Latent Dirichlet Allocation (LDA) implemented in Python (Gensim, spaCy, pyLDAvis), a 17-topic model with a coherence score of 0.5266 was generated. The preprocessing steps included tokenization, lemmatization, bigram/trigram construction, and the removal of both general and domain-specific stopwords. The bibliometric analysis showed that most publications were classified under Social Sciences (93%), with the USA (1961 articles) being the leading contributor. Among the identified themes, “Information, Research, and Technology” (10.59%), “Students’ Information Literacy” (9.22%), and “Information Development” (8.23%) emerged as the most prominent, while “Professional Identity and Practice” (3.37%) and “Education and Research Competency” (3.65%) were underrepresented. Trend analyses revealed that technology-related topics have accelerated significantly since 2010, reflecting the digital transformation of librarianship. In contrast, traditional themes such as “Information Development” and “Health and Medical Services” have declined in momentum. The study shows that digitalization and information literacy remain dominant in the field. In addition, it concludes that significant research gaps exist in professional identity, education, and competency development.

Background. This study investigated the effects of Lactobacillus plantarum supplementation on the Akt/eNOS pathway in the cardiac tissue of rats subjected to a fructose-rich diet, which induced metabolic syndrome. Materials and methods. Twenty-two male Wistar albino rats were randomly assigned to three groups: (1) control, (2) fructose, and (3) fructose ± L. plantarum. Rats in the fructose group were administered a 20% fructose solution in their drinking water for 15 weeks. In the L. plantarum-treated group, the probiotic was administered via gastric gavage at a daily dose of 1×109 CFU/mL/100 g during the final six weeks of the study. Results. The administration of Lactobacillus plantarum resulted in a significant increase in the levels of Akt (p < 0.0001), IRS-1 (p = 0.0113), mTOR (p < 0.0001), eNOS (p < 0.0001), and SIRT1 (p = 0.0031) in the cardiac tissue of rats compared to the fructose group. Moreover, a marked reduction in iNOS, NF-κB, and TNF-α levels (p < 0.0001) was observed, highlighting the potential of L. plantarum to counteract the adverse effects of fructose consumption. Conclusion. The findings of this study suggest that L. plantarum has the potential to reduce inflammation in the heart, enhance insulin sensitivity via the Akt/eNOS pathway, and protect against cardiovascular diseases associated with metabolic syndrome.

Background: The extant research on judo sports has principally concentrated on the physiological effects of training. Conversely, there has been limited attention paid to studies on psychological resilience, self-control, and emotional expression levels. The present study examined the effects of Judo exercises on psychological resilience, self-control, and emotional expression levels in healthy male subjects. Methods: The present study comprised 50 healthy, sedentary male subjects. The subjects were randomly divided into two groups: one group participated in judo training (JT) and the other group served as the control group (CON). The sample sizes for the JT and CON groups were both 25. The JT group underwent judo training, while the CON group maintained their usual lifestyle. The Brief Psychological Resilience Scale, the Multidimensional Brief Self-Control Scale, and the Berkeley Emotion Expression Scale were administered prior to and following the 6-week training period. Results: The study demonstrated that a 6-week judo training regimen exerted a significant effect on the psychological resilience score (e.s. = 1.047, p < 0.001), while no such effect was observed in the Control group (e.s. = 0.0091, p = 0.751). In the context of self-control levels, an effect was observed on the Initiation sub-dimension (e.s. = 1, 739, p < 0.001), yet no effect was found on the Inhibition dimension (e.s. = 0.052, p = 0.892). In the control group, a significant decrease was identified in the Initiation sub-dimension (e.s. = 0, 785, p = 0.001) and Inhibition sub-dimension (e.s. = 1, 861, p < 0.001). The findings indicate that impulse power (e.s. = 0.395) and concealment (e.s. = 0.428) exerted a negligible influence on the emotional expression sub-dimensions. Conversely, psychological resilience (e.s. = 0.886) demonstrated a substantial impact. Conclusions: The judo exercises demonstrated a favorable impact on psychological resilience, self-control, and emotional expression levels in healthy male subjects. The findings of this study may offer significant insights into the impact of judo exercises on psychological resilience, self-control, and emotion expression levels. These findings could serve as a guide for the development of future interventions and program design in the domain of sport psychology.

The current study focused on the ameliorating impact of TRP (5 mM) on Salmo abanticus spermatozoa exposed to sub‑lethal concentrations of GLY (2.5, 5, and 10 mg/L). Sperm quality parameters, oxidative stress indices, and DNA damage were analyzed in the post‑exposure sperm. Our data reveal that GLY has an adverse effect on motility rate and duration, sperm kinetics parameters, antioxidant status and DNA damage, and triggers antioxidant defense mechanisms at the highest dose (10 mg/L) and it has insufficient therapeutic effect. Overall, GLY poses potential hazards to male reproductive cells and may adversely affect subsequent generations of natural populations.

Aydın, Handan; Özen Öner, Ecem; Aydın, Cihat
Tungsten oxide, a versatile transition metal with numerous polymorphs and sub-stoichiometric compositions, containing inherent tunnels and oxygen vacancies, has become a current field of study due to its rich crystal structure, high electrochemical stability, easy accessibility, and environmental friendliness. Thus, the versatile structure of WO3-based materials makes them promising candidates for advanced applications. Our study aims to provide valuable insights into the performance of these materials used in various fields. The structural, optical, and thermal characteristics of PVC-PCL composites doped with tungsten oxide (WO3) were examined in this work. According to DSC research, the thermal characteristics of the polymer matrix were significantly impacted by the addition of WO3. The thermal stability was found to have increased based on the TGA measurement findings. XRD analyses revealed that as the doping rate increased, improved crystallinity was seen. According to SEM tests, the grain clusters are uniformly mixed and the tungsten oxide is evenly spread across the surface. The dopant reacted either chemically or physically with the polymer matrix, according to the ATR-FTIR spectra of PVC-PCL matrix nanocomposite films. An improvement in conductivity with an increase in dopant concentration was noted in the optical experiments. Thus, it can be stated that PVC-PCL composites doped with WO3 can be used in optoelectronic, various industrial, and biomedical application areas due to their structural, optical, and thermal properties.

In this study, it was aimed to determine the effect of sound and light pollution on Zebra mussel (Dreissena polymorpha) by biomarker and nutritional composition. For this purpose, an experimental design was carried out in laboratory conditions where the model was exposed to live sound, light, and combined sound + light parameters for 30 min every hour over 96 h. Changes in the biomarkers superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) activities, as well as glutathione (GSH) and thiobarbituric acid (TBARS) levels, were assessed in the model organism exposed to sound, light, and sound + light pollution. The changes in protein and fat amounts were determined. When the changes in biomarkers were examined statistically compared to the control, there was no significant decrease in SOD activity (p < 0.05), a significant increase in CAT activity in sound and sound+light, but a significant decrease in light (p < 0.05), no significant difference in GPx activity (p > 0.05). It was determined that there was a significant increase in GSH and TBARS levels in all three parameters. Significant changes were also observed in the proximate composition. As a result, exposure to sound, light and sound+light pollution caused an increase in oxidative damage and decreases in protein and lipid composition were detected.

Background: The present study set out to ascertain the effects of combined exercises, consisting of resistance training and plyometric exercises at varying degrees of intensity, on biochemical and respiratory parameters in female volleyball players. Methods: The research group consisted of 20 professional female volleyball players who participated in national and international volleyball competitions. Participants were randomly divided into two groups: a control group (n = 10) that performed low-intensity exercises at 30%–50% intensity, and an experimental group (n = 10) that followed a high-intensity exercise programme at 60%–80% intensity. Blood samples and spirometric respiratory function values were collected before and after the 8-week exercise program. The biochemical analyses included the assessment of luteinizing hormone (LH), growth hormone (GH), insulin-like growth factor-1 (IGF-1), and total iron binding capacity. Respiratory function was analysed using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and forced expiratory flow at mid-expiration (FEF). The data were analysed using the SPSS statistical package. Results: The results demonstrated a decline in IGF-1, GH, and total iron-binding capacity levels, and an increase in LH levels, in the biochemical parameters of the control group. Additionally, FVC, FEV1, and FEF values exhibited an increase in the control group. Conversely, the experimental group demonstrated a significant increase in LH, GH, IGF-1, and total iron-binding capacity levels. With regard to respiratory parameters, an increase in FEF values was observed, whilst FVC and FEV1 values decreased. The present findings suggest that high-intensity plyometric resistance exercises have more pronounced effects on biochemical responses, but may trigger different adaptation mechanisms in respiratory capacit. The results of the study showed that there was a difference between the control group’s GH, IGF-1, FVC, and FEV1 data and the experimental group’s GH, IGF-1, FVC, and FEV1 data. Conclusions: In conclusion, plyometric resistance exercises at varying intensities influence both respiratory and biochemical parameters in female volleyball players. Accordingly, well-planned and individualised plyometric resistance training programmes are thought to enhance both the health and athletic performance of athletes.

This study aims to examine children’s well-being and life satisfaction in terms of various variables related to parents’ and children’s problematic technology usage. Specifically, parent/child responses during their technology use and parents' phubbing and technoference behaviors were considered. The study was conducted with 185 children (8–14) and their parents (mother = 96, father = 89). The data were analyzed by performing correlation analysis, multiple regression analysis, t test, and one-way ANOVA. According to the results, there were negative correlations between children’s life satisfaction and age, children’s technological device (smartphone, computer) usage time, and children/parents responding negatively to each other when engaged in technological devices. Children’s well-being was negatively correlated to their age and children/parents responding negatively to each other when engaged in technological devices. A positive correlation was found between children’s life satisfaction and well-being as well as parents’ phubbing and technoference. According to another result, the well-being of children having their own computer was significantly higher than those who do not have a computer. Finally, children/parents responding negatively to each other when engaged in technological devices negatively predicted the children’s life satisfaction and well-being.

Çobangil, Orçun; Ateş, Erdem
This paper examines how Airbnbification affects the rental market in Istanbul's historic Beyoğlu district using rent gap theory. Given Turkey's recent soaring inflation rates, special emphasis is placed on inflation, aligning with Neil Smith's focus on its impact on rent gap formation. Beyoğlu's history and urban development in the context of neoliberalisation of Istanbul are considered, highlighting why it alone hosts 15.36% of Turkey's Airbnb listings. The analysis proceeds in four stages: first, by comparing long-term rental incomes with Airbnb revenues; second, by assessing inflation and rental growth rates; third, using Pearson correlation to analyse inflation and Airbnbification; and finally, employing the Vector Error Correction Model (VECM) to explore both short- and long-term relationships and Granger causality. These findings suggest Airbnb listings, rising rents, and inflation contribute to the ongoing rent gap, positioning Airbnbification as the latest phase of Beyoğlu's gentrification.

316L stainless steel is widely utilized in various industries due to its excellent corrosion resistance, mechanical strength, and biocompatibility, making it a preferred material for applications in nuclear filed. However, enhancing its radiation shielding and mechanical properties through reinforcement strategies, such as the addition of high-Z materials like Europium(III) oxide, is crucial for extending its functionality in high-radiation environments, where improved performance is essential for safety and durability. In this study, 316L stainless steel composites reinforced with varying amounts of Eu2O3 (1%, 5%, 10%, and 20%) were synthesized and investigated for their structural, mechanical, and radiation shielding properties. X-ray diffraction (XRD) analysis revealed that the face-centered cubic (FCC) structure of the steel matrix was preserved up to 5% Eu2O3 reinforcement, while higher concentrations led to phase formation and crystallographic changes. Scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX) analysis showed uniform element distribution at low reinforcement levels, with particle clustering at 20% Eu2O3. Transmission factors (TFs) were evaluated using PHITS simulations for photon energies of 0.662 MeV, 1.1732 MeV, and 1.3325 MeV. The 20% Eu2O3 composite exhibited the lowest TF and highest attenuation properties, confirmed by mass and linear attenuation coefficients. Elastic modulus values decreased from 224.46 GPa in pure 316L to 189.26 GPa with 20% Eu2O3 reinforcement, reflecting the inverse relationship between mechanical stiffness and radiation shielding performance. Benchmarking against other shielding materials demonstrated superior performance of the Eu2O3-reinforced steel in gamma-ray attenuation. The 20% Eu2O3 composite shows strong potential for applications in nuclear radiation shielding where attenuation efficiency is prioritized over mechanical properties.

Mercury is an industrial toxin with detrimental effects on the reproductive system. This study explored the impact of naringenin (NAR) on testicular toxicity and apoptosis in rats chronically exposed to mercury chloride (MC). The research involved 41 adult male Wistar-Albino rats aged about 2.5 months, which were allocated into 5 groups: group 1 was a control group, group 2 received 100mg/kg of NAR, group 3 was exposed to MC, group 4 received both MC and 50mg/kg of NAR, and group 5 received both MC and 100mg/kg of NAR. For the treatments, the control group took 1mL/kg saline via intraperitoneal (ip) injection and 1mL/kg corn oil via gavage. MC was administered at 0.4mg/kg/day to the MC groups via ip, and NAR was delivered in corn oil at 50 and 100mg/kg/day to the respective NAR groups via gavage. All treatments were performed over a period of 20 days, with MC administration starting 1 hour after NAR administration. The irregularity and loss in spermatogenic cell organization, degeneration and vacuolization in tubules, edema, and congestion in interstitial areas of the testicular tissue of the MC group were alleviated by NAR administration. In addition, the increase in Caspase 3, iNOS, and eNOS immunoreactivities of the MC group were alleviated by NAR administration. In conclusion, it was found that NAR had protective and therapeutic effects against oxidative damage, histopathological changes, apoptosis, and altered spermatological parameters resulting from MC exposure in the testis, and 100mg/kg NAR provided positive effects on altered histopathological analysis, spermatological parameters, and apoptosis.

Dental radiography is used as an important diagnostic tool in the field of dentistry. Dental radiography provides detailed visualization of teeth, jaws and surrounding structures. Dental radiographs are manually interpreted by dentists for diagnosis and treatment purposes. Artificial intelligence methods are successfully applied to automate various image-related processes such as diagnosis and classification. In this study, a hybrid ConvViT model was developed to detect caries, fillings, impacted teeth, implants and normal teeth from dental radiography images. ConvViT combined the advantages of CNN and ViT architectures and provided more successful classification of dental radiography images. ConvViT was compared with popular pre-trained deep learning models such as ResNet-50, VGG-16, EfficientNetB0, and DenseNet201. Experimental results showed that ConvViT outperformed the compared models with 95% accuracy, 95% precision, 94% recall and 94% F-score. ConvViT makes a significant contribution to the development of artificial intelligence-based automatic diagnosis systems in the field of dentistry by effectively modeling both local and long-range features thanks to its hybrid structure.

The Satisfaction With Life Scale (SWLS) is a widely used self-report measure of subjective well-being, but studies of its measurement invariance across a large number of nations remain limited. Here, we utilised the Body Image in Nature (BINS) dataset–with data collected between 2020 and 2022 –to assess measurement invariance of the SWLS across 65 nations, 40 languages, gender identities, and age groups (N = 56,968). All participants completed the SWLS under largely uniform conditions. Multi-group confirmatory factor analysis indicated that configural and metric invariance was upheld across all nations, languages, gender identities, and age groups, suggesting that the unidimensional SWLS model has universal applicability. Full scalar invariance was achieved across gender identities and age groups. Based on alignment optimisation methods, partial scalar invariance was achieved across all but three national groups and across all languages represented in the BINS. There were large differences in latent SWLS means across nations and languages, but negligible-to-small differences across gender identities and age groups. Across nations, greater life satisfaction was significantly associated with greater financial security and being in a committed relationship or married. The results of this study suggest that the SWLS largely assesses a common unidimensional construct of life satisfaction irrespective of respondent characteristics (i.e., national group, gender identities, and age group) or survey presentation (i.e., survey language). This has important implications for the assessment of life satisfaction across nations and provides information that will be useful for practitioners aiming to promote subjective well-being internationally.

Introduction and Objective. Menstrual poverty lies at the intersection of poverty, sustainability, reproductive rights, and gender inequality. The study investigates menstrual poverty among women affected by the 2023 earthquake in Turkey. Materials and Method. A descriptive cross-sectional study was conducted between 24 April – 24 May 2023 with 400 women impacted by the earthquake. Data were collected via social media using a survey form. Chi-square tests, Bonferroni test, and binary logistic regression model were used for statistical analysis. Results. The mean age of participants was 27.27 ± 8.40 years; 69.5% had higher education, 57.0% lived in urban areas, and 90.5% had no chronic disease. A significant relationship was found between access to menstrual products and basic needs (clean water, toilet paper, soap, safe toilet access, and healthcare) during menstruation after the earthquake (p<0.05). A significant correlation was also observed between disruptions to the menstrual cycle and the following variables: lack of privacy, perception that lack of privacy affected menstruation, healthcare access, and difficulty obtaining menstrual products (p<0.05). Conclusions. Most participants faced difficulties accessing menstrual products, water, hygiene supplies, privacy, and healthcare. Those living in tents or containers reported greater challenges. These barriers contributed to menstrual poverty and impacted women’s cycles. As menstrual health and hygiene are basic needs and human rights, menstrual poverty must be addressed globally.
