Uysal, Ibrahim; Akmaz, Recep Melih; Su, Ben-Xun; Demir, Yilmaz; Sen, Ahmet Dundar
The chromitites of the K & imath;z & imath;lda & gbreve; ophiolite (KO) are primarily characterized by massive and disseminated textures within refractory mantle peridotites, predominantly harzburgite and dunite, with occasional occurrences of banded and nodular chromitites. Based on chromite composition, these chromitites can be classified into two groups exhibiting a broad compositional range: intermediate (0.55 <= Cr# < 0.70, TiO2 = 0.08-0.51 wt%) and high-Cr (0.70 <= Cr# <= 0.77, TiO2 = 0.05-0.28 wt%). The compositions of minor and trace elements align consistently with variations in Cr#. Total PGE (Os, Ir, Ru, Rh, Pt, Pd) contents in these chromitites are generally less than 500 ppb, with many samples showing enrichment of IPGE (Os, Ir, Ru) relative to PPGE (Rh, Pt, Pd). However, certain samples from both groups display elevated PGE concentrations (Sigma PGE(intermediate) = 718 ppb, Sigma PGE(High-Cr) = 866 ppb) compared to other samples. The dominant platinum group mineral inclusions in chromite are Ru-rich laurite [(Ru, Os)S-2], with a single osmiridium (Os-Ir alloy) grain also observed suggesting formation under high-temperature and low & fnof;S-2 conditions. Primary base metal mineral inclusions include millerite and pentlandite. Additionally, some chromite crystals contain single or multi-phase silicate inclusions, such as clinopyroxene, orthopyroxene, olivine, and amphibole. Parental melt compositions, calculated from Al2O3 and TiO2 contents of chromites, indicate that most high-Cr chromitites originated from boninitic melts, whereas intermediate chromitites and some high-Cr samples derived from melts with intermediate compositions. Trace element compositions of amphibole and clinopyroxene inclusions in the chromite crystals from the intermediate group further support crystallization from hydrous intermediate melts. It is proposed that the intermediate chromitite group formed from partial melts influenced by fluids from the subducted oceanic crust during the early stages of subduction initiation, while high-Cr chromitites originated from hydrous melts derived from a more depleted mantle wedge in later stages.

Background: Although numerous treatment modalities exist for Prostate Cancer (PCa) with a complex pathophysiology, a significant worldwide health concern for males, early identification remains the paramount factor influencing disease prognosis. Proposed new biomarkers, including GSTP1, PTEN, and NKX3.1, may provide predictive and prognostic functions, hence enhancing the efficacy of PSA in diagnosing prostate cancer. Epigenetic variables associated with nutrition influence the blood gene expression levels of the new biomarkers GSTP1, PTEN, and NKX3.1. This study aimed to elucidate the correlation between nutrition-related epigenetic variables and the expression of the tumor suppressor genes GSTP1, PTEN, and NKX3.1 in benign prostate and prostate cancer patients. Methods: This study was conducted with 41 newly diagnosed prostate cancer and 42 benign prostate patients, all aged 40 years and older. Participants had specific anthropometric measurements taken, and seven-day food records were kept. Serum levels of novel biochemical markers GSTP1, PTEN, and NKX3.1 were measured using an Enzyme-Linked Immunosorbent Assay (ELISA) method. Expression analyses of tumor-protective GSTP1, PTEN, and NKX3.1 genes were performed on prostate tissues obtained from fresh prostate biopsies taken from the groups and were associated with nutritional status. Results: A significant relationship was found between the serum levels of GSTP1, PTEN, and NKX3.1, which are important in the formation and treatment of prostate cancer, and Gleason grade, tumor stage, and surgical margin status (p < 0.05). However, significant relationships were found between many macro and micronutrients obtained from the dietary pattern and effective in epigenetic pathways and GSTP1, PTEN, and NKX3.1 gene expressions (p < 0.05). Conclusions: The findings of this investigation corroborated the notion that prospective novel markers, including GSTP1, PTEN, and NKX3.1, may serve predictive and prognostic functions in prostate cancer, hence enhancing the efficacy of PSA in its diagnosis. Dietary trends may influence the optimization of many epigenetic processes. Targeted therapeutic nutritional interventions designed to enhance gene expression will facilitate the formulation of prostate cancer prevention methods.

Dönmez, Cahit; Aral, Zehra Deveci; Saka, Samet; Günay, Kurtulus; Yildirim, Nail; Yildirim, Esra; Yagcioglu, Kiymet Deniz; Maqsud, Isoqov; Movlanov, Jakhongir; Dovronovich, Mamarozikov Usmonjon
The Central Asian Orogenic Belt's ophiolites lack a full ophiolitic succession and instead occur as irregular fragments and slices in tectonic melanges and accretionary complexes. The Teskuduk and Northern Nurata ophiolites in Uzbekistan comprise extensively serpentinized mantle rocks that contain minor podiform chromitites, situated in the western area of the southern Tien Shan belt. Chromites in this region are found in a very limited area, and this study aims to determine the geochemical properties and formation environments of chromites by conducting geochemical studies on a limited number of recently discovered chromitites. In this context, mineral chemistry and platinum group element (PGE) geochemistry analyses were carried out on chromites. For Teskuduk chromitites, the Cr2O3, Al2O3, and TiO2 contents range from 53.2 to 55.7wt%, 11.1 to 12.7wt%, and 0.14 to 0.20 wt%, respectively, whereas for Nurata chromitites, the corresponding values range from 36.2 to 37.2 wt%, 23.1 to 30.2 wt%, and 0.10 to 0.30 wt%. The Teskuduk and Nurata chromitites contain a total average of 370 ppb and 117 ppb PGEs, respectively. They are classified as unfractionated chromitites, with low Pd/Ir ratios (0.03-0.20). These chromitite samples have chondrite-normalized PGE patterns that are identical to Cr-rich mantle-derived chromitites found in subduction-related ophiolites. Collectively, these data suggest that the Teskuduk ophiolites formed in a forearc setting, whereas the Nurata ophiolites evolved in a back-arc setting within the same oceanic branch.

Öztekin, Aynure; Öztekin, Coskun; Sahin, Humeyra Nursel; Karadeniz, Tuba Betul; Senel, Engin; Caliskan Atac, Damla; Savci, Unsal; Neselioglu, Salim; Erel, Ozcan
Recurrent aphthous stomatitis is an inflammatory disease characterized by painful ulcers on the oral mucosa. Oxidative stress is held responsible for the pathogenesis of this disease of unknown etiology. In oxidative stress, the balance between oxidant-antioxidant substances changes in favor of the oxidative side. Ischaemia modified albumin (IMA) is a new type of albumin. It occurs as a result of factors such as ischemic attacks and oxidative stress. The aim of the study was to compare IMA levels in patients with recurrent aphthous stomatitis with healthy volunteers and to investigate whether IMA has a diagnostic value in the disease. This cross-sectional study included 32 patients with recurrent aphthous stomatitis and 34 healthy volunteers of similar age and sex. Albumin and IMA levels were determined by spectrophotometric albumin cobalt binding assay in venous blood samples on the same day. IMA was expressed as absorbance unit. Receiver operating characteristic analysis was used to determine whether IMA values could be a diagnostic marker for prediction of disease. IMA values of the patient group were significantly higher than IMA values of the control group (P < .001). IMA was statistically significant in the prediction of recurrent aphthous stomatitis (P < .001). The discrimination power for IMA was very good (area under the receiver operating characteristic curve 95% CI = 0.952 [0.897-1.000]). Recurrent aphthous stomatitis, in which oxidative stress plays a role in the etiopathogenesis, is closely associated with high IMA levels. IMA levels may have diagnostic value as an indicator of oxidative stress in the disease.

Objective: This study aimed to investigate the potential splenic tissue damage induced by radiotherapy (RT) and the potential protective effect of different doses of dexmedetomidine on this damage at the histopathological, immunohistochemical, and biochemical levels. Materials and Methods: In our study, Sprague Dawley rats were randomly divided into four groups: Control, Radiotherapy (RT; 8 Gy), RT + Dexmedetomidine 100 mu g/kg (RT-D100), and RT + Dexmedetomidine 200 mu g/kg (RT-D200). A single dose of 8 Gy radiotherapy was administered to each RT group. Spleen tissues were examined histologically with hematoxylin-eosin and immunohistochemically with anti-Caspase-3, anti-TGF-beta 1, and anti-TGF-beta 3 using light microscopy. TBARS and total thiol levels were also analyzed to assess oxidative stress and antioxidant capacity. Results: Histopathological results showed a significant decrease in white pulp diameter, decreased cellular density, and increased congestion in the red pulp in the RT group. Significant fibrosis, sinusoidal dilatation, vacuolization, and amyloid deposition were detected in the white pulp in the RT group. Regarding anti-caspase-3 immunoreactivity, strong positivity increased in the red pulp in the RT group, while a significant increase was observed in the white pulp in both the RT-D100 and RT groups. While the proportion of TGF-beta 1 immunopositive cells did not change significantly in the RT group, they increased significantly in both dexmedetomidine groups (especially RT-D200). TGF-beta 3 expression increased significantly only in the RT-D100 group. In biochemical analyses, TBARS levels increased significantly in the RT-D100 group. Total thiol levels decreased in the RT group and increased in the dexmedetomidine-treated groups. Conclusions: While RT caused histopathological damage and increased oxidative stress in spleen tissue, dexmedetomidine reduced this damage in a dose-dependent manner. The different immunohistochemical profiles of TGF-beta 1 and TGF-beta 3 suggest that these cytokines may have different functions in the spleen. 100 mu g/kg dexmedetomidine stimulates a regenerative response through TGF-beta 3, while 200 mu g/kg dexmedetomidine may provide immune regulation and antioxidative defense through TGF-beta 1.

Background: Athlete's heart encompasses cardiac adaptations to long-term intensive training. Although male-dominated sports have been widely studied, limited data exist on structural and functional cardiac remodeling in female contact-sport athletes. This study aimed to evaluate cardiac changes in elite female rugby players using conventional and strain echocardiography. Methods: This cross-sectional study included 66 elite female rugby players and 50 sedentary controls. Anthropometric measurements and transthoracic echocardiographic assessments, including speckle tracking-derived global longitudinal strain (GLS), were performed. Linear, multivariable, and partial correlation analyses evaluated associations between GLS, active playing years (APY), and body mass index (BMI). Results: Compared to controls, athletes exhibited increased ventricular diameters, wall thicknesses, and left atrial size, with preserved left ventricular ejection fraction (LVEF). GLS values were significantly lower in rugby players (p < 0.001), though within normal limits. APY and BMI both showed significant inverse correlations with GLS (r = -0.456 and -0.370, respectively). In multivariable analysis, APY (beta = -0.392, p = 0.001) and BMI (beta = -0.225, p = 0.013) independently predicted GLS. Partial correlation confirmed the independent association of APY with GLS (r = -0.412, p = 0.001). GLS showed strong discriminative performance for >= 5 years of play (AUC = 0.816) and moderate performance for BMI >= 24.13 (AUC = 0.666). Conclusion: Elite female rugby athletes demonstrate physiological cardiac remodeling, including reduced GLS associated with training duration and BMI. These findings highlight the need for sex- and sport-specific echocardiographic reference values and further longitudinal research to clarify long-term clinical implications.

Çimen, Okay; Gücer, Mehmet Ali; Simonetti, Antonio; Karaoglan, Fatih
The Dodurga Pluton is located within the Central Pontides (northern Turkiye), has a SW-NE elongation, and consists of granodiorite and dacite porphyry. Previous studies have suggested that this pluton is Triassic in age, and its whole-rock geochemical systematics is consistent with that from adakitic magmatic occurrences rather than the classic arc granitoid suite. This study reports for the first time in situ/whole-rock radiogenic isotopic (Sr, Nd, and Pb) and mica/amphibole Ar-Ar age data to evaluate better its petrogenetic/geodynamic evolution and the chemical nature of mantle source(s). Unlike previous data, combined new in situ zircon U-Pb yield Late Cretaceous crystallization ages of 84.2 +/- 0.9 Ma and 86.9 +/- 0.9 Ma, and the Ar-Ar age data along with apatite fission track measurements suggest magma cooling extending to 82.3 +/- 0.4 Ma and 85.4 +/- 0.4 Ma, respectively. The apatite fission track (AFT) dating results also reveal that this pluton was buried at a depth of 2.5-3 km following a fast-cooling period during the Late Cretaceous and cooled/exhumed over similar to 2 km during the Middle-Late Miocene (15-10 Ma) in a slow cooling phase. The overall data reported here suggest that the Dodurga Pluton represents melts derived from an enriched/metasomatized mantle source that interacted with lower crustal mafic rocks in an active continental margin as a result of northward subduction of the northern branch of the Neotethys Ocean.

Ayaydin, Hasan; Ergün, Tolga; Barut, Abdulkadir; Erdem, Azad; Pilatin, Abdulmuttalip
The increasing emphasis on climate change and environmental sustainability worldwide has brought about the convergence and increased focus on financial technologies (FinTech) and green energy initiatives. In light of this, the study's objective is to investigate how FinTech moderates the relationship between the ecological footprint (EF) and green energy transition (GTE) in the BRICS-T nations between 1990 and 2021. This study examines how fintech moderated the GTE and EF in the BRICS-T from 1990 to 2021. We applied the Fully Modified Ordinary Least Squares (FMOLS) and used Dynamic Ordinary Least Squares (DOLS) as the main estimators for longitudinal analysis. In contrast, Driscoll-Kraay was used to verify the robustness of the results under cross-sectional dependence and heteroskedasticity. The results reveal that FinTech indirectly hinders EF by facilitating GTE. The outcomes also show that FinTech significantly constrains EF, while GDP and industrialization worsen EF. The results also confirm the important role of GTE and foreign direct investment (FDI) in reducing CO2 emissions in BRICS-T countries. Lastly, the paper offers policymakers useful recommendations for lowering EF in light of these outcomes. The study suggests establishing appropriate policies and strategies that encourage FinTech platforms to invest in green energy projects, including financial technology, promoting energy-efficient and low-carbon foreign direct investment, and encouraging GTE.

Background: This study examines the acute effects of neuromuscular electrical stimulation (NMES) application on peak power (PP) and mean propulsive power (MPP) during a weighted squat jump (SJ(Loaded)). Methods: Fourteen male students (age: 23.71 +/- 2.30 years; height: 173.71 +/- 6.89 cm; weight: 69.59 +/- 9.08 kg; body mass index (BMI): 26.87 +/- 3.49) from the Faculty of Sport Sciences participated voluntarily. PP and MPP values were measured during the SJ(Loaded) movement, performed with an external load of 40% body weight, using a computer-integrated linear velocity transducer system (T-Force Dynamic Measurement System Ergotech Consulting SL, Murcia, Spain). NMES was bilaterally applied to the musculus hamstring and musculus quadriceps femoris for 20 minutes. The Shapiro-Wilk test, skewness and kurtosis values assessed data normality. Results: Differences between pre- and post-test PP and MPP power performances were analyzed using Paired Samples t-tests. Cohen's d (ES: effect size) and 95% confidence intervals (CI) were also calculated to assess the pairwise comparisons' magnitude. According to the analysis results, statistically significant improvements were observed in both PP (t (13) = -2.612, p = 0.021, d: -0.69 (-1.27; -0.10, 95% CI)) and MPP (t (13) = -2.756, p = 0.016, d: -0.73 (-1.32; -0.13, 95% CI), moderate effect) values after the NMES application. Conclusions: NMES significantly enhances PP and MPP during loaded squat jumps, highlighting its potential as a supplementary training tool for improving explosive power. Future studies should explore its long-term effects across different sports and populations, such as female athletes or older adults, to optimize training protocols. Research on NMES intensities and frequencies may provide insights into optimal parameters for power development and neuromuscular adaptation.

Background:This quasi-experimental crossover study aimed to examine the acute effects of dry cupping therapy (DCT) and neuromuscular electrical stimulation (NMES) on fatigue and perceived exertion in anaerobic performance among physically active individuals.Methods:Twelve male participants (mean age: 24.1 +/- 2.37 years), all students from the Faculty of Sports Sciences, were recruited to participate voluntarily. Anaerobic performance parameters, including peak power, mean power (MP), and fatigue index (FI), were assessed using a Monark 839E cycling ergometer under 3 distinct conditions: NMES, DCT, and a control condition (no intervention), with each session separated by a 48-hour rest period. Perceived exertion was evaluated immediately following each test session using Borg's rate of perceived exertion (RPE) scale. Both NMES and DCT were administered bilaterally to the hamstring (m. hamstring) and quadriceps femoris (m. quadriceps femoris) muscles for 20 minutes before testing.Results:The results revealed no statistically significant differences in peak power and MP across the conditions. However, significant effects were identified for FI (F(2, 22) = 4.08, P = .031, eta p(2) = 0.27) and RPE (F(2, 22] = 8.88, P = .0015, eta p(2) = 0.45). Post hoc pairwise comparisons indicated that NMES significantly reduced FI compared to the control condition (P = .0311), with a small to medium effect size (Cohen's d = 0.44). In terms of RPE, DCT significantly lowered values compared to both the control (P = .0018) and NMES conditions (P = .0005), demonstrating medium (Cohen's d = 0.74) and small to medium (Cohen's d = 0.37) effect sizes, respectively.Conclusions:While NMES and DCT did not elicit acute improvements in peak or mean anaerobic power, both interventions effectively mitigated fatigue and reduced perceived exertion during maximal anaerobic exercise. These findings suggest that NMES and DCT may serve as valuable recovery modalities for mitigating fatigue in sports characterized by high anaerobic demands. Future research should investigate the chronic effects of these interventions and explore their utility among trained athletes to determine their broader applicability in enhancing athletic performance.

Ceylan, Hüseyin; Kaplan, Ahmet
Occupational accidents and death cases resulting from occupational accidents are among the most critical factors threatening work peace. Occupational accidents cause injury, disability and even death for many employees. In 2021, 1394 employees died due to occupational accidents in Turkey, while 3123 became permanently incapacitated, that is, disabled for life. In addition, tens of thousands of employees were injured in occupational accidents, resulting in temporary incapacitation and exposing them and their families to emotional distress. The fact that occupational accidents are preventable events to a large extent makes the incidents caused by occupational accidents, such as death, loss of limb, and severe injury due to occupational accidents, even more tragic. Especially multiple-fatality occupational accidents are accepted as an indicator of the importance countries place on human life. Human life is above any economic value. Turkey is the country with the worst performance in Europe in terms of fatal occupational accident incidence rates. For all these reasons, in this study, fatal occupational accidents in Turkey in 2012-2022 were analyzed with the Health and Safety Labour Watch-Turkey (HESA Labour Watch) data. In addition, Social Security Institution (SSI) data for 2012-2021 was compared with the HESA Labour Watch data, and it was examined whether fatal occupational accidents were officially recorded. Finally, using official SSI data, Turkey and EU-27 countries were compared regarding the number of death cases resulting from occupational accidents and fatal occupational accident incidence rates. The study revealed the following results; Some of the fatal occupational accidents cannot be recorded in Turkey, After the OSH law, the number of death cases as a result of occupational accidents increased, compared to the EU-27 countries, Turkey has the worst performance in terms of both the number of death cases as a result of occupational accidents and the fatal accidents incidence rate.

The impact of shadow banking on financial stability remains a controversial issue today due to the size and complexity of these activities and the inadequate regulatory frameworks for systemic risks. In this context, shadow banking has become the focus of financial regulators due to its potential effects on financial stability. Therefore, this study was conducted to understand the impact of shadow banking on financial stability. In this study, the relationship between shadow banking and financial instability is examined using the VAR method for the example of the United States, covering the period 2000-2020. In order to create an accurate model, firstly unit root tests were performed, followed by autocorrelation and heteroscedasticity tests. The findings were found to be significant and Johansen cointegration test was applied. In the cointegration results, it was seen that the series were cointegrated, that is, they moved together in the long run. Finally, a Granger causality test was conducted between shadow banking and financial instability, and according to the empirical findings, it was concluded that there was a causality from shadow banking to financial instability for the period in question.

(Alieva), Vildane Özkan
Başat Bulgar kültüründe geçmiş zaman dilimi, bugün ve gelecek zaman dilimlerinden çok daha etkin rol oynar. Osmanlı Devleti’nin, İkinci Bulgar İmparatorluğu’nu fethederek Bulgarlar üzerinde 1393-1878 yılları arasında kurduğu egemenlik dönemi, başat Bulgar kültüründe “Türk köleliği” dönemi olarak damgalanır. Bu damga, 19. yüzyılda inşa edilerek günümüze kadar sürdürülür. Bulgar kültüründe geçmişe yönelik “Türk köleliği” damgası; günümüzde politika, diplomasi, resmi ve resmi olmayan eğitim, hukuk, din, tören ve bayramlar, folklor, film, sanat, edebiyat, tarih, geleneksel medya, sosyal medya, protesto meydanları vs. gibi birçok kurumsal ve gündelik alanı kuşatmış durumdadır. Ancak bu damga, belirsiz bir tarihsel anlatıya dayandırılır ve oryantalist bir çerçevede biçimlenir. Diğer yandan, günümüzde söz konusu damgayla ilgili Bulgarlar tarafından yöneltilen kısmi eleştiriler de mevcuttur. Makale, Bulgarlar üzerindeki Osmanlı Devleti egemenliği dönemine ilişkin “Türk köleliği” damgasının hangi toplumsal-kültürel koşullarda nasıl inşa edildiği ve günümüzde hangi alanlarda nasıl yeniden üretildiğiyle ilgili sosyolojik bir çözümlemeden oluşur. Konu, büyük ölçüde özgün Bulgarca kaynaklardan elde edilen veriler üzerinden araştırıldı. Çözümlemenin kuramsal boyutunda, Said’in oryantalizm, Goffman’ın damga, Bourdieu’nun alan, Foucault’nun sorunsallaştırma ve Parsons’ın işlev kavramlarından yararlanılmaktadır. Türkçe sosyolojik yazında Bulgar kültürüyle ilgili araştırmaların sayısı yok denecek kadar azdır. Bu nedenle makale, Türkçe sosyolojik yazına bir katkı sağlamayı da amaçlar.

Çakir, Günay; Sivrikaya, Fatih; Bozali, Nuri
Orman ekosistem hizmetleri; tedarik, düzenleyici, destekleyici ve kültürel hizmetleri bünyesinde barındırmaktadır. İnsanlar ve canlıların ekosistemden doğrudan veya dolaylı olarak elde ettiği faydalar çok çeşitlidir. Ekosistemin sunduğu düzenleyici hizmetler sürdürülebilir kalkınma ve insan yaşamı açısından önem arz etmektedir. Aynı zamanda ekosistem hizmetleri insan refahı ile yakından ilişkilidir. Yaşamın en temel taşlarından birisi de su kaynaklarıdır. Dünya yüzeyinde kullanılabilir suyun çok az olması ve su kaynaklarının insanlara sunduğu hizmetlerin artması bu önemi daha da artırmıştır. Su döngüsünün faydalı bir biçimde kullanılması için evapotranspirasyon süreçlerinin de belirlenmesine ihtiyaç duyulmuştur. Faydalı suyun depolanmasında barajlar inşa edilmektedir. Baraj havzaları içerisinde mevcut arazi örtüsünün korunması ya da geliştirilmesi gerekmektedir. Bu çalışmada, bazı ülkelerdeki içme suyu havzalarındaki ormancılık çalışmaları ile ekosistem hizmetleri arasındaki ilişkiler ele alınarak Trabzon ilinin içme suyu ihtiyacının yaklaşık %70’ini sağlayan Galyan (Atasu Baraj) havzasındaki orman ekosisteminin sürekliliği açısından değerlendirmelerde bulunulmuştur. Orman ekosistemi ile su üretiminin karşılıklı etkileşimlerine değinilmiştir.
