Aygün, Tayfun; Keskin, Arif; Palanci, Ozgur; Öztanir, Mustafa Namik; Yücel, Nurullah; Hekimoglu, Gulam
Aim This study aimed to evaluate the independent prognostic value of the contralateral DTI-ALPS index in IDH-wildtype glioblastoma, incorporating tumor morphometry, extent of resection, and sex-stratified analyses within a multivariable framework.Methods A retrospective analysis was performed on 153 IDH-wildtype glioblastoma patients from the publicly available UPENN-GBM dataset. Contralateral DTI-ALPS was calculated using DSI Studio via manual ROI placement; tumor morphometry was derived from expert-annotated segmentation labels using 3D Slicer. Survival analyses included Kaplan-Meier estimation, multivariable Cox regression, time-dependent ROC, restricted cubic spline, and sequential C-index comparison with likelihood-ratio testing.Results The contralateral DTI-ALPS index independently predicted overall survival after adjustment for age, sex, tumor volume, and GTR status (HR = 0.405, 95% CI: 0.227-0.725, p = 0.002). Each one standard deviation increase in DTI-ALPS was associated with a 24.2% reduction in mortality risk. GTR >= 90% (HR = 0.651, p = 0.017) and age (HR = 1.021, p = 0.007) also retained independent significance. DTI-ALPS significantly improved model discrimination beyond age alone (C-index: 0.625 -> 0.653 -> 0.668; likelihood-ratio test p = 0.002). Time-dependent AUC reached 0.741 at 6 months. ALPS-based stratification was more pronounced in the subtotal resection subgroup. Sex-stratified analyses showed numerically stronger associations in females, but formal interaction testing did not confirm effect modification. In an exploratory MGMT subset (n = 57), DTI-ALPS did not retain independent significance after MGMT adjustment.Conclusion The contralateral DTI-ALPS index may provide complementary prognostic information beyond established clinical predictors in IDH-wildtype glioblastoma; however, given the incomplete MGMT methylation data and ongoing methodological debate regarding the biological validity of DTI-ALPS, these findings should be considered exploratory. Prospective validation in cohorts with complete molecular and treatment data is required.

Background Today, people increasingly embrace the natural process of aging while seeking to age gracefully and elegantly. As a result, there has been growing interest in facelift and facial rejuvenation techniques. Patients tend to prefer methods that refresh the facial expression, offer natural-looking results, and leave minimal scarring. Objectives The authors describe a new technique and its tips that include short-scar facelift in addition to forehead and midface lift, especially for patients between the ages 35 and 50 with moderate skin sagging and excess. This procedure also includes intervention on the platysma muscle and all major retaining ligaments. Methods Seventy-four patients, all female, who were operated on with the TemFa lift technique described by the author, were evaluated with midface area measurements and Brow Positioning Grading Scale (BPGS), and the preoperative and postoperative results are presented. Results Compared with the preoperative results, the ratio of the upper midface area (P1) to the lower midface area (P2) increased significantly in the postoperative period (p < 0.05), while the BPGS results decreased significantly (p < 0.05), resulting in a younger eyebrow height and position. After the operation, the square face appearance is replaced by a more youthful V-shaped face. Conclusion TemFa lift technique can be considered as a suitable surgical technique for patients between the ages 35 and 50 who have moderate excess skin and sagging but also want some improvement in the neck and jawline area.

Providing ethical care for people living with dementia is essential for safeguarding their rights, dignity, and well-being. However, ethical decision-making in dementia care is complex, often involving tensions between competing moral claims such as autonomy, beneficence, nonmaleficence, justice, and non-discrimination. This scoping review aimed to map and describe the ethical principles, related normative considerations, and ethical frameworks discussed in the scientific literature on dementia care, and to identify how these have been conceptualized. Following the methodological guidance of Arksey and O'Malley (2005), Levac et al. (2010), and Peters et al. (2021, 2022), a comprehensive search across five databases (Web of Science, Scopus, CINAHL, Medline/PubMed, and PsycInfo) identified peer-reviewed papers published in English. In total, 388 papers published between 1981 and 2024 were included. The results revealed a wide range of ethical principles and related normative considerations frequently cited in the literature, although they were typically discussed in an isolated way without reference to other principles or broader ethical frameworks. In contrast, ethical frameworks were mentioned far less often, and when they were, they mostly reflected traditional approaches such as principlism. Four gaps were identified: the plurality of ethical frameworks and limited conceptual integration underpinning dementia care research and practice; insufficient attention to ethnic and socioeconomic diversity among people living with dementia; limited consideration of diverse care settings and geographical regions; and the limited inclusion of people living with dementia themselves in the studies reviewed. These findings underscore the need for conceptually integrative, inclusive, and context-sensitive approaches to dementia care ethics that can better inform both ethical reflection and care practices.

Akyol, Mehmet; Zuhal, Mustafa; Mete, Emrullah; Lorente, Daniel Balsalobre; Barut, Abdulkadir
The agricultural sector plays a vital role in ensuring food security and supporting sustainable economic growth. However, climate change and global warming pose significant challenges to the long-term viability of agricultural production, underscoring the need for sustainable agricultural practices. Adopting clean technologies and environmentally responsible policies is essential for balancing economic and agricultural sustainability while minimizing ecological harm. Supportive and protective agricultural inputs are widely used to enhance productivity, yet excessive, unregulated use can lead to environmental degradation. This deterioration negatively impacts ecosystems, reducing biodiversity and straining natural resources. The Load Capacity Factor (LCF) serves as a critical metric for assessing the environmental footprint of agricultural activities. This paper investigates the effects of agricultural value-added, pesticide use, and fertilizer application on LCF in BRICS-T countries. The findings indicate that these variables exhibit long-term cointegration, with varying short- and long-term impacts. To ensure the sustainability of agricultural production while safeguarding ecosystems, it is essential to integrate clean technologies, precision farming, and regenerative agricultural practices into policy frameworks. Sustainable agricultural systems and environmentally conscious policies are fundamental to securing resilient food production and long-term economic stability.

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.

Benedikt, M.; Zimmermann, F.; Auchmann, B.; Bartmann, W.; Burnet, J. P.; Carli, C.; Chancé, A.; Craievich, P.; Giovannozzi, M.; Grojean, C.
Volume 1 of the FCC Feasibility Report presents an overview of the physics case, experimental programme, and detector concepts for the Future Circular Collider (FCC). This volume outlines how FCC would address some of the most profound open questions in particle physics, from precision studies of the Higgs and EW bosons and of the top quark, to the exploration of physics beyond the Standard Model. The report reviews the experimental opportunities offered by the staged implementation of FCC, beginning with an electron-positron collider (FCC-ee), operating at several centre-of-mass energies, followed by a hadron collider (FCC-hh). Benchmark examples are given of the expected physics performance, in terms of precision and sensitivity to new phenomena, of each collider stage. Detector requirements and conceptual designs for FCC-ee experiments are discussed, as are the specific demands that the physics programme imposes on the accelerator in the domains of the calibration of the collision energy, and the interface region between the accelerator and the detector. The report also highlights advances in detector, software and computing technologies, as well as the theoretical tools/reconstruction techniques that will enable the precision measurements and discovery potential of the FCC experimental programme. The content and structure of this report are guided by the scope and priorities defined in the mandate of the FCC Feasibility Study. It is therefore not intended to serve as an exhaustive review of the full physics potential of FCC. Several topics, already covered in earlier reports such as the FCC CDR, are not reiterated here or are addressed only briefly, in alignment with the study's focus. This volume reflects the outcome of a global collaborative effort involving hundreds of scientists and institutions, aided by a dedicated community-building coordination, and provides a targeted assessment of the scientific opportunities and experimental foundations of the FCC programme.

BackgroundUterine leiomyosarcoma is a rare and aggressive malignancy with limited responsiveness to standard therapies. We conducted a real-world, multicenter study to compare the clinical efficacy and safety of two commonly used first-line chemotherapy regimens-doxorubicin-ifosfamide and gemcitabine-docetaxel-in patients with metastatic uterine leiomyosarcoma.MethodsThis retrospective cohort included 271 patients with advanced or metastatic uterine leiomyosarcoma treated between 2010 and 2023 across 30 centers in Turkey. Patients received either doxorubicin-ifosfamide (n = 142) or gemcitabine-docetaxel (n = 129) as first-line therapy. The primary endpoint was overall survival; secondary endpoints included progression-free survival, objective response rate, disease control rate, and safety. Adverse events were graded according to the Common Terminology Criteria for Adverse Events version 5.0, while survival outcomes were estimated using the Kaplan-Meier method and further analyzed with Cox proportional hazards models.ResultsMedian overall survival was 19.7 months with doxorubicin-ifosfamide and 20.2 months with gemcitabine-docetaxel (P = .26). Median progression-free survival was 5.5 months with doxorubicin-ifosfamide and 7.0 months with gemcitabine-docetaxel (P = .62). The objective response rate was numerically higher with gemcitabine-docetaxel (35% vs. 26%), although not statistically significant (P = .11). Grade 3-4 neutropenia (16% vs. 12%) and febrile neutropenia (7% vs. 6%) were more frequent with doxorubicin-ifosfamide.ConclusionsIn this largest-to-date real-world cohort of metastatic uterine leiomyosarcoma, doxorubicin-ifosfamide and gemcitabine-docetaxel demonstrated comparable survival outcomes. Gemcitabine-docetaxel, however, was associated with a more favorable hematologic safety profile. These findings support the clinical utility of both regimens while underscoring the need for prospective, biomarker-driven studies to refine treatment selection and improve personalization in this rare malignancy.

Crackers are popular bakery products known for their crunchy texture and long shelf life. Typically made from leavened or unleavened dough with wheat flour, oil, water, and additives, crackers have undergone recipe enhancements to improve sensory and nutritional profiles. While many studies explore cracker and biscuit formulations, fruit seed oils remain underexplored. Fruit seeds, often discarded as waste, are rich in essential fatty acids, amino acids, and micronutrients. Oils from seeds such as grape, pomegranate, rosehip, and apricot have gained attention for their health benefits, which presents an opportunity for innovation in bakery products. This study evaluated the potential of incorporating various fruit seed oils (pomegranate, apricot kernel, grape, fig, and rosehip) into cracker formulations. Crackers were assessed for physicochemical properties, antioxidant activity, mineral content, texture, and sensory attributes, with sunflower oil as the control. Results showed that the addition of fruit seed oils significantly influenced cracker properties. Crackers with apricot kernel oil had the highest ash content (2.29 +/- 0.13%) and exhibited a more acidic character, as did those with grape seed oil. Moisture content decreased significantly when rosehip seed oil was used (P < 0.05). Grape seed oil yielded the highest water-holding capacity, while sunflower oil provided the highest oil-holding capacity. Crackers made with rosehip and apricot kernel oils demonstrated improved antioxidant properties. Using fruit seed oils not only enhances nutritional value (e.g. vitamins, minerals, antioxidants, and dietary fiber) but also reduces material waste, contributing to sustainability and better resource utilization.

The significant natural energy sources for reducing the global usage of fossil fuels are renewable energy (RE) sources. Solar energy is a crucial and reliable RE source. Site selection for solar photovoltaic (PV) farms is a crucial issue in terms of spatial planning and RE policies. This study adopts a Geographic Information System (GIS)-based Multi-Influencing Factor (MIF) technique to enhance the precision of identifying and delineating optimal locations for solar PV farms. The choice of GIS and MIF is motivated by their ability to integrate diverse influencing factors, facilitating a holistic analysis of spatial data. The selected influencing factors include solar radiation, wind speed, Land Surface Temperature (LST), relative humidity, vegetation, elevation, land use, Euclidean distance from roads, and aspect. The optimal sites of solar PV power plant delineated revealed that 'very low' suitability of site covering 4.866% of the study area, 'low' suitability of site 13.190%, 'moderate' suitability of site 31.640%, 'good' suitability of site 32.347%, and 'very good' suitability of site for solar PV power plant encompassing 17.957% of the study area. The sensitivity analysis results show that the solar radiation, relative humidity, and elevation are the most effective on the accuracy of the prediction. The validation of the results shows the accuracy of solar PV power plant prediction using MIF technique in the study area was 81.80%. The integration of GIS and MIF not only enhances the accuracy of site suitability assessment but also provides a practical implementation strategy. This research offers valuable insights for renewable energy policymakers, urban planners, and other stakeholders seeking to identify and develop optimal locations for solar energy power farms in their respective regions.

The estimation of heat transfer coefficients (HTC) and pressure drop (Delta P) in flow boiling processes is essential for the effective design and operation of refrigeration systems. In this study, the artificial neural network (ANN), locally weighted regression (LWR), and gradient boosted machine (GBM) methods are employed to predict the boiling heat transfer coefficient (HTC) and pressure drop (Delta P\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}Δ P\end{document}) in flow boiling of R134a. The study focuses on horizontally positioned both straight and microfin tubes. The ANN, LWR, and GBM methodologies are utilized to ascertain the parameters of boiling HTC and Delta P as outputs. These parameters are determined by considering the mass flux, saturation pressure, heat flux, vapor quality, Reynolds number, Lockhart-Martinelli parameter, Froud number, Weber number, and Bond number as inputs. The training dataset is partitioned into 5 sections for the purpose of hyperparameter tweaking for each model. Out of these sections, 4 parts, consisting of approximately 111 samples, are utilized for training, while 1 part, including around 27 samples, is allocated for validation. The optimal hyperparameters are determined by calculating the average R2 score over the 5 validation sets. Using raw measurements, HTC and Delta P are successfully modeled using a relatively much smaller dataset of 174 measurements, with 82.4% R2 score and 0.7% weighted average relative deviation for HTC, and 88.9% R2 score and 4.1% weighted average relative deviation for Delta P across multiple tube types, achieved by LWR algorithm. Model performances are validated with an extrapolation test and found to be consistent with traditional train-validation-test sampling scheme with 75.9% R2 score and -6.2% weighted average relative deviation for HTC, and 89.3% R2 score and -3.9% weighted average relative deviation for Delta P, showing the consistency of the hypotheses created by a hybrid of parametric and nonparametric model families even outside the observed measurement range for multiple tube types. Local weighted regression models are the most performant, especially for limited data availability. However, calculated measurements increase error rates, suggesting that HTC and Delta P models work best with raw measurements.

BackgroudTwelve taxa of herbaceous Paeonia species were recorded in Turkiye. All definitions were performed morphologically and/or anatomically and there is no study based on DNA barcode sequences. Three barcode regions were sequenced to determine the phylogenetic relationships of Turkish Paeonia taxa. The chemical comparison of roots was also investigated.Methods and resultsThe taxons were collected between May and June 2021 from nine cities. Leaf materials were used for DNA isolation and ITS, matK and rbcL regions were amplified and sequenced. There was no difference among taxa in terms of rbcL sequences. But the ITS and matK regions distinguished 12 taxa and structured them in two groups. ITS region distinguished P. peregrina, P. arietina, and P. tenuifolia from other taxa, while matK region distinguished P. arietina and P. witmanniana from other taxa. Both barcode sequences actually showed that the registration of P. mascula subsp. arasicola was actually 100% similar to P. arietina. ITS was the most polymorphic region (n = 54) followed by matK (n = 9). These sequences could successfully discriminate Paoenia species from each other and diploid P. tenuifolia. The methanolic root (100 gr) extracts were examined for total phenolic and flavonoid content, and antioxidant activities. Significant variation was found for polyphenolic content, and antioxidant properties (TPC from 204.23 to 2343.89 mg, TFC from 7.73 to 66.16 mg, and FRAP from 523.81 to 4338.62 mg). SC50 values of ABTS and DPPH were ranged from 115.08 to 1115.52 mu g/ml and 73.83 to 963.59 mu g/ml, respectively.ConclusionIt was concluded that 11 of 12 taxa had differences in terms of ITS and matK sequences and these region must be used for the correct identification of Turkish Paeonia.

Dokuz, Abdurrahman; Gücer, Mehmet Ali; Karsli, Orhan; Yi, Keewook
New U-Pb zircon data from the Kurtoglu Massif (eastern Sakarya Zone, Turkey) reveal a Cadomian back-arc basin, evolving to closure of the Rheic Ocean. A host metapsammite from the lower tectonic slice of the massif yielded detrital zircon ages ranging from Neoarchean (2.73 Ga) to late Neoproterozoic with a major population between 610 and 553 Ma and a peak at 592 Ma, implying that the basement of the Sakarya Zone has a Cadomian affinity. This metasedimentary sequence was intruded by an orthogneiss in the early Ordovician (481 Ma) probably during the opening of the Rheic Ocean. Zircon grains from the overlying metasedimentary sample yielded concordant ages spreading throughout the Mesoproterozoic (1608-1032 Ma) and early Paleozoic (516-351 Ma), suggesting that they were deposited in the Rheic Ocean likely prior to its final closure. The muscovite metagranite, emplaced into the host rocks of the Kurtoglu Massif at 388 Ma, formed probably during northward closure of the Rheic Ocean. Zircon grains of a metasiltstone from the upper tectonic slice of the massif, represented mainly by phyllites, yielded similar age spectra to that of the host metapsammite of the lower tectonic slice. Such phyllites in the Pulur Massif similar to 35 km to the southeast display a close association with the ophiolitic complexes of the Rheic Ocean. This relationship together with the age spectra mentioned above suggests that sedimentation was on a place away from the Paleozoic igneous sources, in an analogous position to the southern passive margin of the Rheic Ocean.

Menevseoglu, Ahmed; Aykas, Didem Peren; Adal, Eda
Pistachio is one of the most expensive nuts with having high economic importance in Turkey. It has become more prone to adulteration because of its high commodity value. Peanut with color additives and green pea are generally used to adulterate ground pistachio. Vibrational spectroscopy is a potential technique to detect adulterations in pistachio. The objective of this study was to generate a non-targeted method for portable FT-IR and UV-Vis spectrometers to authenticate pistachio and detect green pea and peanut adulterations. Pistachio granules were adulterated with green pea and peanut at different concentrations (5 to 40% w/w). Spectra were collected by a portable FT-IR spectrometer and by a conventional UV-Vis spectrometer and analyzed by Soft Independent Modeling of Class Analogy (SIMCA) to generate classification algorithms to authenticate pistachio, and Partial Least Square Regression (PLSR) to predict the concentrations of adulterants. SIMCA showed very distinct clusters for pure samples. Moreover, adulterated pistachio samples were discriminated by SIMCA even in low levels of adulteration (5%). Portable FTIR showed excellent performance (r(val) > 0.93) of predicting the adulterant levels with a standard error of prediction (SEP) 0.66% and 0.80% for green pea and peanut, respectively. Similarly, UV-VIS predicted (r(val) > 0.93) the adulterant levels with SEP 0.58% and 0.14% for green pea and peanut, respectively. The results supported that portable FT-IR, and UV-Vis units present great potential for real-time surveillance of green pea and peanut adulteration in pistachio.
