Karakaya, Hanife; Colakoglu, Zafer; Acarer, Ahmet; Ozkurt, Ahmet
Objectives: The study aimed to develop a measurement method that yielded objective data for the clinical assessment of cervical dystonia using a Kinect camera system. Patients and methods: This double-blind, parallel-group method development study included 22 patients with cervical dystonia (3 males, 19 females; mean age: 47 years; range, 34 to 60 years) and 20 healthy individuals (13 females, 7 males; mean age: 32 years; age range, 22 to 65). Using cameras and a computer software, the head-neck postures of 40 healthy participants were recorded in the virtual environment. Using the device, 22 patients with cervical dystonia were examined both at rest and while moving with different parts of the body. Two different experts evaluated and scored the cases using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) and the Tsui scale. Results: A three-way comparison revealed interclass correlations between the coefficients of 0.799 (79.9%) and 0.784 (78.4%) for at rest and with movement, respectively. The two-way comparison of the experts revealed correlation coefficients of 0.717 (71.7%) and 0.692 (69.2%) for at rest and with movement, respectively. A three-way comparison of the device and Expert 1 and Expert 2 TWSTRS scores revealed interrater agreement values of 0.6 and 0.8 (good) and 0.6 and 0.8 (good) while at rest and with movement, respectively. A three-way comparison of the device and Expert 1 and Expert 2 Tsui scores revealed interrater agreement values of 0.6 and 0.8 (good) and 0.4 and 0.6 (moderate) while at rest and with movement, respectively. Conclusion: The newly developed system was a sensitive tool for use in the kinematic evaluation of patients with cervical dystonia and could prove beneficial in diagnosis and treatment follow-up.

Bülbül, Kenan; Türkkan, Tugba; Meriç, Cagdas Salih; Yilmaz, Haci Omer
Eating disorders are a problem that negatively affects physical and psychological development and can potentially be life-threatening. In order to successfully combat this disorder, it is important to have a better understanding of the underlying mechanisms. The aim of this study is to examine the mediating role of impulsivity in the relationship between internet addiction and eating disorders in an adolescent sample. The current research was designed in accordance with the correlational model. The study group was formed by convenience sampling method among students who continue their education in secondary schools and high schools in Trabzon. The data of the study were collected with a demographic information form prepared by the researchers, the Young Internet Addiction Test-Short Form, Rezzy Eating Disorders Scale and Barratt Impulsivity Scale-Short Form. As a result of statistical analysis, it was determined that the average eating disorder score of female students was higher than that of male students. It was found that the eating disorder scores of those whose income was less than their expenses were significantly higher than those whose income was more than their expenses. Positive significant relationships have been identified between internet addiction and eating disorders. It has also been determined that impulsive behavior plays a mediating role in the relationship between internet addiction and eating disorders. It is thought that the current findings will contribute to the understanding of the mechanisms underlying eating disorders and the development of effective prevention and intervention strategies.

Yilmaz, Coskun; Ceylan, Tulay; Altunbas, Adem; Soylu, Hakan Huseyin; Kavuran, Korhan; Söyler, Mehmet
Purpose: The objective of this study was to examine the impact of trapezius muscle thickness measurements on bench press single repetition maximum (1RM) power output. Material and Methods: The study included 13 male bodybuilders who participated in national and international professional natural bodybuilding competitions and 13 healthy sedentary male subjects. Body composition, 1RM values and ultrasonographic measurements of trapezius muscle thickness were obtained from the participants. Results: The findings revealed that both the skin-to-superficial muscle tissue (R1, L1) and skin-to-deep fascia (R2, L2) distances were significantly lower in sedentary individuals compared to bodybuilders (p<0.001). Additionally, 1RM strength output was significantly higher in bodybuilders than in sedentary individuals. In sedentary individuals, a moderate negative correlation was observed between the distance between superficial muscle and 1RM, and a low positive correlation was observed between the distance between deep fascia and skin surface. In contrast, a low negative correlation was found in both parameters in bodybuilders. Conclusion: Our findings indicate that trapezius muscle thickness is significantly lower in sedentary individuals compared to bodybuilders, both in superficial and deep tissue layers. We believe that the skin surface imaging method used in our study could be an effective tool for predicting injuries in athletes. Additionally, we believe that regular imaging follow-ups in athletes could provide important information about adaptations in muscle structures resulting from applied training stimuli.

Cagatay, Diren Vuslat; Balci, Mecdi Gurhan; Issin, Gizem; Demir, Fatih
BackgroundEnhancer of zeste homolog 2 (EZH2), the catalytic subunit of Polycomb Repressive Complex 2, catalyzes trimethylation of histone H3 lysine 27 and has been implicated in tumor progression.AimOur study aims to assess the relationship between EZH2 expression and clinicopathologic data, and survival in colorectal carcinomas (CRC).Materials and methodsEZH2 immunohistochemistry was performed on tumor blocks from 124 CRC patients. Based on H-scores, cases were stratified into low- and high-expression groups. EZH2 status was correlated with demographic, clinical, and pathologic features, and overall survival was analyzed with the Kaplan-Meier method and log-rank test.ResultsA total of 124 cases of CRC; 12 (9.7%) cases were classified as low EZH2 expression, and 112 (90.3%) cases were classified as high EZH2 expression. A significant association was found between EZH2 expression and microsatellite stability. High EZH2 expression was significantly enriched in microsatellite-stable tumors (p = 0.007) and in left-sided lesions (p = 0.049). No significant associations were detected with sex, stage, grade, lymph-node status, or vascular invasion. Kaplan-Meier analysis revealed no difference in overall survival between low- and high-EZH2 groups (log-rank p = 0.47; hazard ratio = 1.13, 95% CI 0.45-2.85). EZH2 staining was uniformly strong in normal mucosa and adenomas, mirroring the high expression observed in most CRCs.ConclusionsEZH2 is highly expressed across the normal-adenoma-carcinoma sequence and, in our cohort, was not linked to overall survival or to most clinicopathologic parameters in CRC. The lower expression observed in a subset of MSI-H tumors warrants further investigation; present evidence remains insufficient to establish EZH2 as an independent prognostic biomarker.

Pala, Fahrettin; Görgün, Mehmet Ragip; Torusdag, Mustafa; Demirtas, Furkan; Barut, Abdulkadir
The current study explores the impact of global gold price uncertainty on the stock markets of the MIST countries: Mexico, Indonesia, South Korea, and T & uuml;rkiye. The study examined the crisis periods that started with the COVID-19 pandemic and continued with the Russia-Ukraine war, which caused uncertainty in gold and oil prices. Based on this, the study's data set consists of the daily closing prices between March 11th, 2020, and January 31st, 2023. The obtained data were analyzed using the Least Squares (ICC) and panel quantile regression (PQR) methods. There is a significant positive correlation between oil prices and oil volatility index with stock prices for the economies of T & uuml;rkiye, Indonesia, and Mexico, and a significant negative correlation between gold prices and gold volatility index with stock prices for developing countries. There is also a significant positive relationship between gold and oil prices and stock prices for the developed country, South Korea's economy. A significant negative correlation has also been proposed between gold and oil volatility indices and South Korean stock prices. This study provides a novel contribution to the literature by examining the impact of simultaneous global crises namely the COVID-19 pandemic and the Russia-Ukraine war-on the stock market indices of MIST countries through the lens of uncertainty in both gold and oil markets. While most existing studies focus on a single commodity or analyze crises in isolation, this research distinguishes itself by investigating the combined effects of two major global shocks and incorporating both price and volatility-based uncertainty indicators. The findings suggest that policymakers should develop country-specific and differentiated financial stability policies by taking into account the uncertainties in gold and oil markets during crisis periods.

Güler, Ilkay; Naimoglu, Mustafa; Simsek, Orhan; Adali, Zafer; Özbek, Sefa
This study investigates the impact of economic growth and foreign direct investment (FDI) on China's sustainable development goals (SDGs), specifically Zero Hunger (SDG 2), Life Below Water (SDG 14), and Life on Land (SDG 15). It examines ecological footprints and load capacity factors (LCFs) in cropland, fishing, forest, and grazing land using Fourier bootstrap autoregressive distributed lag (ARDL) cointegration analysis and fully modified ordinary least squares (FMOLS) estimators. The study covers the period from 1979 to 2022. Key findings reveal that while GDP and FDI often exacerbate environmental degradation, urbanization and value-added agriculture, forestry, and fishing (FAFGDP) improve sustainability in some areas. The study confirms the pollution haven hypothesis for most models, suggesting that China's legal and regulatory frameworks may inadequately mitigate FDI's adverse environmental effects. The Environmental Kuznets Curve (EKC) hypothesis is not supported as GDP growth generally increases ecological footprints. However, trade openness and urbanization show positive influences on environmental sustainability. Policy recommendations include enhancing energy efficiency, promoting renewable energy, implementing green technologies in agriculture and urban development, and revising FDI policies to incentivize environmentally friendly practices. These strategies are crucial for achieving China's sustainable development goals and mitigating the pressures of human activities on natural resources.

This study aims to examine the relationship between physical performance levels and cognitive functions of male athletes aged 18-25 years competing in the Turkish Hockey Indoor 1st League. 45 athletes participated in the study, balance, flexibility and vertical jump tests and D2 Attention Test were applied. In addition to descriptive statistics, independent samples t-test, one-way analysis of variance (ANOVA) and Pearson correlation analysis were used to analyze the data. The results revealed that attention levels did not differ significantly according to age, education, sport experience and position (p>0.05). While there was no significant relationship between physical performance variables and attention, only vertical jump values showed a significant difference between the positions (p<0.05). In addition, positive and significant correlations were observed between the sub-dimensions of the attention test. In this context, it was concluded that not only physical criteria but also cognitive skills should be systematically included in the performance evaluations of hockey athletes.

Millions of people are grieving the loss of someone who died of COVID-19. The current study aims to validate a Kurdish version of the Pandemic Grief Scale which is a brief English-language mental health screener to identify cases of dysfunctional grief associated with a COVID-19 death. We recruited 501 participants. Participants completed the PGS, WSAS, PHQ-9, and Optimism scales. The factor structure, reliability, and validity of the PGS were analyzed. Using exploratory factor analysis (N1 = 300), we derived an one-factor structure. In confirmatory factor analysis (N2 = 201), the one-factor model showed good to excellent fitness. The PGS was positively correlated with PHQ-4, and WSAS and negatively correlated with optimism. The scale was internally consistent with a Cronbach's alpha of .79. These results support that the Kurdish version of the PGS is a valid and reliable assessment to assess the severity of dysfunctional grief associated with a COVID-19 death.

Çelik, Necati; Özen, Songul Akbulut; Engin, Burhan
We propose a quantum interferometric protocol that leverages spin-dependent spatial displacements to enable high-precision parameter estimation beyond classical limits. By inducing a unitary coupling between a particle's spin degree of freedom and its momentum, the protocol generates entanglement between spin states and spatial positions, resulting in coherent spatial superpositions. Interferometric reconstruction of the resulting phase differences enables Heisenberg-limited sensitivity for parameters encoded in the spin Hamiltonian. As a concrete application, we demonstrate the protocol's effectiveness in magnetic field sensing, where the field is transduced into spatial interference fringes. Quantum Fisher information analysis confirms sub-shot-noise scaling, and the protocol's feasibility is discussed for physical platforms including ultracold atoms and nitrogen-vacancy centers. Our framework provides a versatile approach to quantum metrology with potential extensions to multiparameter sensing and gravitational wave detection.

Urban memory, defined as the accumulation of human experiences within human settlements, is largely shaped around examples of spatial and architectural art. As different cultural environments participate in the formation of urban memory, the accumulation of the settlement also becomes richer. This richness, which carries the traces of civilisations through the ages to the present day, can also be observed in the & Ccedil;& ouml;mlek & ccedil;i Neighbourhood, which forms one of the eastern suburbs of Trabzon and takes its name from the pottery production industry. The neighbourhood is home to cultural layers from the Hellenistic Period Mithra Cult, the Roman and Byzantine Empires, the Komnenos Kingdom, the Ottoman and Republican periods, as well as Catholic Italians, Orthodox Greeks, Mitharist Armenians and Muslim Turks. The neighbourhood's significance extends beyond its multiple cultural layers; as an area of artistic and artisanal production, it makes a significant contribution to the city's budget and vitality. Raising awareness of the neighbourhood is crucial for the integration of fragments of the city's memory. This study compiles new findings added to the existing knowledge about & Ccedil;& ouml;mlek & ccedil;i Mahallesi. The neighbourhood, which bears witness to rich experiences alongside its architectural structure, has been examined in terms of urban memory, centred on the discipline of art history alongside its multiple cultural layers, and studied within a hermeneutic framework that incorporates meaning and interpretation through the criteria of definition, witnessing, surface research, and evaluation.

Myosotis amoena Boiss. (Turkish name: Ho & scedil; boncukotu) is a perennial herbaceous plant that produces blue flowers during the spring. Phytochemicals, which are secondary metabolites distributed across plants, fungi, microorganisms, and even animal tissues, play crucial roles in health through their antioxidant and bioactive properties. Their antioxidant capacity largely arises from hydroxyl groups and aromatic ring structures that stabilize free radicals via electron delocalization. Enzyme inhibition is a therapeutic strategy in several diseases, including Alzheimer's disease (AD), where acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitors are employed to manage symptoms. This study investigated the phytochemical composition (via LC-MS/MS), total phenolic content, antioxidant capacity, and AChE/BChE inhibitory effects of the ethanol extract of M. amoena using four in vitro methods. The CUPRAC assay demonstrated that M. amoena (1.070) exhibited higher antioxidant activity than Trolox (0.894), although its activity in FRAP, ABTS, and Fe3+ reduction assays was lower compared to standard antioxidants. The extract contained 53.03 mg GAE/g extract of total phenolics, with rosmarinic acid being the predominant compound (15.27 mg/g). Furthermore, the extract strongly inhibited AChE and BChE, with IC50 values of 3.9 and 19.8 mu g/mL, respectively. These findings highlight, for the first time, the significant bioactive potential of M. amoena as a natural source of antioxidants and cholinesterase inhibitors, supporting its prospective use in the prevention or management of neurodegenerative conditions.

Until 2016, two subspecies of Neurergus strauchii were identified; at this time, one more subspecies was described from Tunceli as N. s. munzurensis. However, this study mainly focused on morphological characters. We aim to test of Neurergus species, including N. s. munzurensis taxa by phylogenetic analysis, using partial base sequences of 12S rRNA and D-loop genes. For this purpose, we reconstructed Bayesian Inference and Maximum Likelihood trees with other Neurergus samples. According to the results, phylogenetic tree topologies demonstrate that N. crocatus was separated from the N. strauchii-N. barani lineage and the N. strauchii group have shown monophyly. Also, N. s. munzurensis showed higher genetic distances with N. barani (1.1%) and N. s. strauchii (0.8%) while genetic distances were only determined as 0.5% within N. barani and N. s. strauchii. N. s. munzurensis was found to be a genetically distinct taxon, following its previous morphological description. This study obtained the first evidence on better explaining the taxonomic status of N. s. munzurensis.

Colorectal adenocarcinoma infrequently exhibits a diffuse, poorly cohesive architecture and a gastric-type immunophenotype, closely resembling diffuse-type gastric carcinoma and posing a formidable diagnostic challenge. This report describes a 65-year-old woman who presented with non-specific abdominal discomfort and was found by colonoscopy to have a 6.5 cm ulceroinfiltrative lesion in the hepatic flexure. Histologically, the tumor comprised discohesive cells with focal signet-ring morphology, accompanied by extensive lymphovascular and perineural invasion, necrosis, and a marked peritumoral lymphoid response. Immunohistochemical analysis demonstrated a gastric-type profile (CK7+, CK20-, SATB2-, CDX2 weak/focal, MUC5AC+, MUC2-), whereas panels excluding breast, urothelial, M & uuml;llerian, neuroendocrine, and hematolymphoid differentiation were uniformly negative. Comprehensive imaging and endoscopic evaluation excluded an extra-colonic primary malignancy/ carcinoma. Mismatch repair testing revealed loss of MLH1/PMS2 expression with preserved MSH2/MSH6. This case underscores that, in such uncommon colorectal variants, reliance on immunophenotype alone may mislead, and that definitive diagnosis necessitates integrated clinicopathologic correlation, exhaustive sampling, and exclusion of alternative primaries/primary malignancies/carcinomas to confirm a primary colonic poorly cohesive adenocarcinoma with focal signet-ring differentiation.

Recent evidence suggests that spinal manipulation can acutely improve mobility and lower-limb performance. This study compared the acute effects of lumbar and sacroiliac chiropractic manipulation on flexibility nd jump performance. Forty-five healthy male participants were randomly assigned to three groups: a Lumbar Manipulation Group (LMG; n = 15), a Sacroiliac Manipulation Group (SMG; n = 15), and a Control Group (n = 15). Flexibility was assessed using the V-Sit and Reach test, while performance was evaluated with vertical and horizontal jump tests. Lumbar manipulation was applied to the dysfunctional lumbar segment in the LMG, and sacroiliac joint manipulation was applied to the dysfunctional sacroiliac region in the SMG. No intervention was performed in the control group. Both manipulation techniques resulted in significant acute improvements in mobility and jump performance compared with the control group (p < 0.05), with the greatest improvement observed in vertical jump height (p = 0.001). No significant differences were found between the LMG and SMG. Spinal manipulation to the lumbar and sacroiliac regions appears to produce acute improvements in mobility and lower-limb power. These findings suggest that spinal manipulation may serve as a short-term performance-enhancing intervention.

The energy sector has relatively higher exposure to scandals and controversial publicity due to the nature of industry operations. AThus, this study focuses on the energy sector to evaluate the impact of ESG (Environmental, Social and Governance) controversy scores of LSEG database on market value of firms. We investigate the relationship between ESG controversies and the market value of 393 firms using annual data from 2013 to 2022 through Dynamic Panel Data system GMM Regression Models. The findings of the study reveal that the market value of firms in the previous period has had a statistically significant positive effect on the market value of firms in the current period. Our analysis reveals a positive and statistically significant association between Governance Controversy scores and market value. Our findings suggest governance controversies have the most direct and measurable impact on firm value in the energy sector, possibly due to their stronger influence on operational performance and investor confidence. Implications of the study may help investors and policymakers to make decisions that prioritize ESG considerations in the energy sector as firms with fewer governance controversies are rewarded by investors with higher valuations.

Karayígít, Iskender; Yilmaz, Fetullah
Imam al-Rabbani (d. 1034/1624), who came to the forefront in Islamic history mostly with his Sufi identity and was known as the sheikh of the order, although he mostly focused on Sufism, stood against the efforts to distort Islam during his lifetime and struggled in the theological and political fields. In this context, he made efforts to ensure the failure of Akbar Shah's (d. 1014/1605) project of Din-i Ilahi. In addition to his important works in the fields of sufism and theology, Imam al-Rabbani was also interested in many issues of Islamic jurisprudence (fiqh) and its history. As a person who inherited the legacy of his predecessors, he felt the need to speak on many issues related to fiqh. One of these is the criticism made about Ab & umacr; Hanifa (d. 150/767) and his school of thought. Imam al-Rabbani, especially in his work Makt & umacr;bat, was involved in the debates around the concepts of ahl al-ra'y and ahl al-hadith, and naturally tried to defend the Hanafi sect to which he belonged and its imam Ab & umacr; Hanifa with a number of evidences from different perspectives. He objected to the characterization of the Hanafi imams as mere ra'yists (lit. opinionists), stating that they accepted hadiths but also had their own methods of deriving rulings. Again, he was not contented with only some 'scientific' evidences in his discussion of Hanafism, but he also strengthened his defense with spiritual, allegorical, and mystical arguments, such as the similarity between Jesus Christ and Ab & umacr; Hanifa in ijtihad, the fact that Jesus would act in accordance with the Hanafi school of thought after his descent, and the fact that Hanafi sect possesses the perfection of prophethood. By responding to the claims of the opponents in this way, Imam al-Rabbani tried to justify the Hanafi school of thought. In this article, some of the spiritual-ischemic qualities that Imam al-Rabbani attributed to Hanaf is and his responses and defenses to the allegations put forward by some ahl al-hadith scholars will be discussed.

Çelik, Kamil; Tas, Ahmet
Nowadays, social media influencers play a significant role in the world of marketing. Social media influencers reach large audiences by producing content on social media platforms, and they exert considerable impact on these audiences. The literature suggests that social media users form parasocial relationships, and these relationships develop based on the influencer's characteristics, such as attractiveness, expertise, credibility, and similarity. It has also been proven in various studies that social media influencers have a strong effect on increasing the purchasing intentions of their followers. In this study, the effects of social media influencers on parasocial relationships and the purchasing intentions of their followers were examined. The research was conducted among Instagram users in Turkey, and the data were collected using a survey method. The survey included statements aimed at measuring elements such as parasocial relationships, attractiveness, expertise, credibility, and similarity. Because of the data analysis, it was found that characteristics such as influencers' attractiveness and expertise strengthen parasocial relationships, and these relationships positively influence followers' purchasing intentions. Additionally, the perception of fairness also had a significant impact on these relationships. These findings suggest that social media influencers can be an effective tool in marketing strategies.

Akyüz, Ahmet Mutlu; Durmus, Ibrahim
It is essential for young Turkish individuals (university students) to rapidly develop their skills and abilities to take on leadership roles in society. To become well-equipped individuals who contribute to societal welfare and development, these young adults must undergo a healthy adolescent maturity process. Therefore, providing a supportive environment for Turkish adolescents during their maturation is crucial. This study investigates how fulfilling all hierarchical needs (PSN, LBN, ESAN) affects Turkish adolescents' life satisfaction (LS) and their personal (PM), familial (FM), and social (SM) maturity levels. The study sample consists of 397 Turkish university students. The proposed research model was tested using PLS-SEM analysis. The findings indicate that fulfilling all hierarchical needs positively affects life satisfaction. Additionally, life satisfaction serves as a mediator between the fulfillment of hierarchical needs and maturity levels. However, the most fundamental physical and security needs are not adequately met, hindering personal maturity. Furthermore, love and belonging needs and esteem and self-actualization needs positively impact all maturity levels.
