    Cutting Regimes and Nitrogen Rates Affect Forage Nutritive Value, Biomass, and Grain Yield in Dual-Purpose Wheat

    No full text
    Dual-purpose wheat farming is a system that enables the production of high-quality forage for livestock during winter and early spring without reducing the land allocated to grain production. The objectives of this study were to investigate the effects of nitrogen (N) rate and cutting regimes on grain yield, biomass accumulation and the nutritive value of dual-purpose wheat. Field trials were conducted over two crop seasons (2021-2022 and 2023-2024) using a split-plot arrangement within a randomized complete block design with three replications. Nitrogen rates (0, 60, 120, and 180 kg ha(-)& sup1;) were assigned to main plots and cutting regimes to sub-plots. Single cutting was performed at the Zadoks 30 stage, while double cutting included a first cut at Zadoks 25 followed by a second cut 30 days later. Biomass accumulation increased with increasing N rates, and forage protein concentration reached its highest value at the highest N rate. Other forage nutritive value traits, including neutral detergent fiber, acid detergent fiber, digestible dry matter intake, and relative feed value, showed limited variation among N rates. Biomass accumulation differed between cutting regimes depending on the season, with higher values under single cutting in the first season (18.70 Mg ha(- 1)) and under double cutting in the second season (18.51 Mg ha(- 1)). Grain yield did not differ between the 120 kg ha(- 1) N rate (4.29 and 4.30 Mg ha(- 1) in the first and second seasons, respectively) and the 180 kg ha(- 1) N rate (4.98 and 4.81 Mg ha(- 1)). Forage production was higher at the 180 kg ha(- 1) N rate (2.77 and 2.55 Mg ha(- 1) in the first and second seasons, respectively). Cutting regimes reduced grain yield in both seasons, with greater reductions in the second season. Regression analysis indicated strong relationships among agronomic, structural, and nutritional traits in dual-purpose wheat

    Unlocking surgical precision: intraoperative MRI in endoscopic skull base surgery, a meta-analysis

    No full text
    Objective: Intraoperative magnetic resonance imaging (iMRI) is increasingly used in purely endoscopic endonasal skull base surgery (EESBS) to improve surgical accuracy. Given its high cost and logistical demands, quantifying its clinical utility is essential for evidence-based implementation. This meta-analysis was conducted to evaluate the clinical efficacy of iMRI in purely endoscopic endonasal skull base surgery. Methods: PubMed, Scopus, and Web of Science databases were searched in accordance with PRISMA guidelines. The last search was conducted on November 7, 2024. Eligible studies were original research articles reporting outcomes of ≥ 6 patients undergoing purely endoscopic endonasal skull base surgery with iMRI. Studies using microscopic or combined approaches were excluded. Primary outcomes included gross-total resection rates, iMRI-detected residual tumor, and rates of additional resection prompted by intraoperative imaging. Results: Twenty-seven studies involving 1,871 patients were included. iMRI increased overall GTR by 19.6% (95% CI, 3.7%-35.5%) and by 18.4% (95% CI, 13.9%-22.8%) in pituitary adenomas. Unexpected residual tumor was detected in 19.7% of cases initially presumed complete, leading to immediate further resection in 32.4% of patients. False-positive rates were negligible, and false-negative rates were low (3.5%). Conclusion: Intraoperative MRI significantly improves the extent of resection and intraoperative decision-making in purely endoscopic skull base surgery, particularly for pituitary tumors. However, evidence for rarer pathologies such as craniopharyngiomas and chordomas remains limited. Standardized selection criteria and randomized controlled trials are needed to define optimal use and assess cost-effectiveness

    The relationship between mental fatigue awareness and effective decision-making levels of athletes: the role of mediating and moderating variables

    No full text
    This study examined the mediating role of psychological well-being and the moderating roles of gender and sport type (individual vs. team) in the relationship between mental fatigue awareness and intrinsic decision-making in 540 Turkish athletes. Research data were collected online via three different measurement tools. Results indicated a significant indirect effect of mental fatigue awareness on intrinsic decision-making through psychological well-being (indirect effect β = −0.087, p .05). Similarly, neither gender (β = 0.083, p >.05) nor the interaction between gender and mental fatigue awareness (β = 0.100, p >.05) significantly predicted intrinsic decision-making. The study contributes to understanding the interplay of mental fatigue awareness and intrinsic decision-making in athletes, considering the influences of gender and sport type. Future studies should employ longitudinal and experimental designs to clarify causality and to evaluate targeted dual-pronged interventions that address both psychological well-being and mental fatigue management

    Classification and Biological Function of ncRNAs (lncRNAs and circRNAs) in Plants.

    No full text
    Non-coding RNAs (ncRNAs) are molecules that play important biological roles in plant growth but lack coding capacity. They are widely distributed in all living species. The advancement of high-throughput sequencing technology (RNA-seq) has enabled the identification of various ncRNAs. Their activities and mechanisms of action have become increasingly clear. Recent studies indicate that ncRNAs are critical for plant growth, development, and responses to environmental stress. In particular, elucidating miRNA-lncRNA-circRNA interaction processes will help identify genetic adaptations in plant stress resistance. The categorization of lncRNAs, their roles, and mechanisms in plant responses to environmental challenges are briefly summarized. The functions of ncRNAs in root and leaf development, plant growth and development, dormancy, germination, and flower formation are emphasized. Long non-coding RNAs (lncRNAs) function as sponges, precursors, scaffolds, and regulatory complexes, and serve as transcription factors (TFs) and chromatin modification structures. lncRNAs serve as regulators in epigenetics and significantly influence processes such as chromatin network remodeling and DNA methylation.&nbsp;</p

    A bibliometric exploration of affective factors in mathematics education: research trends, thematic evolution, and topic modeling

    No full text
    This study aims to examine research trends in the field of affective factors in mathematics education between 1978 and 2025 using trend topic analysis. A total of 2,587 articles systematically collected from the Web of Science and Scopus databases were analyzed using topic modeling, hierarchical clustering, and multidimensional scaling techniques. The findings reveal that the volume of research in the field has steadily increased, but there has been a shift in thematic focus from broad topics to more specific and contextual areas. While “math anxiety” emerged as the most dominant research focus, teachers’ affective characteristics (Topic 4) and math anxiety (Topic 6) were the fastest growing themes in recent years. In contrast, the intersection of technology and materials with affective factors (Topic 1) and positive psychology-focused concepts (enjoyment, curiosity, flow) have been insufficiently researched. Hierarchical clustering showed that the topics fell into two main clusters: teaching/achievement-focused (Topics 2, 4, 5, 6) and context-factor-focused (Topics 1, 3, 7). The study highlights the asymmetric distribution and research gaps in the field, suggesting that future studies should focus on areas such as positive psychology, integrated theoretical models, and technology-based interventions. Furthermore, the importance of teacher training and math anxiety intervention programs is emphasized

    The relationship between functional level, cognitive status, sleep quality and quality of life in patients with Alzheimer’s disease: a cross-sectional study

    No full text
    Background: Functional deficits and loss of cognitive functions in patients with Alzheimer’s disease (PwAD) may affect activities of daily living (ADLs), sleep quality and quality of life (QoL). However, studies investigating the multiple relationship between cognitive status, functional level, ADL, sleep quality and health-related QoL in PwAD are limited. Objectives: This study was to investigate the multiple relationships among functional level, cognitive status, sleep quality, and QoL in PwAD. Methods: A total of 47 individuals diagnosed with mild to moderate Alzheimer’s disease were included. Cognitive status was assessed using the Montreal Cognitive Assessment. Motor function was evaluated via the Rivermead Motor Assessment. ADLs were measured using the Modified Barthel Index and Katz ADL Scale. Sleepiness levels were determined using the Epworth Sleepiness Scale, sleep quality was assessed with the Pittsburgh Sleep Quality Index, and QoL was evaluated using the Alzheimer’s Disease-Related Quality of Life Scale. Results: The study demonstrated that as cognitive impairment progressed in PwAD, functional limitations in ADLs increased, while sleep quality significantly declined (r = −458, p < 0.05). Both cognitive decline and ADLs limitations were independently associated with reduced sleep quality, and this interplay may contribute to the deterioration of overall QoL (r = −0.475, p < 0.05). Furthermore, higher educational attainment was found to be protective against cognitive decline (p < 0.05). Conclusions: These findings reveal the importance of preserving cognitive and functional levels in PwAD, and suggest that sleep quality should be routinely evaluated in these patients

    No full text
    This methodological study aimed to adapt the Loneliness Inventory for Older Adults (LIOA) into Turkish and to evaluate its validity and reliability. The sample consisted of 384 older adults who presented to a family health center in Turkey between May and December 2024. Data were collected using a Personal Information Form, the LIOA, and the UCLA Loneliness Scale Version 3. The Turkish version of the LIOA revealed a five-factor structure comprising 29 items, with factor loadings between 0.794 and 0.903. Goodness-of-fit indices indicated an excellent model fit (chi 2/df = 1.564, CFI = 0.978, GFI = 0.908, NFI = 0.943, IFI = 0.978, TLI = 0.976, RMSEA = 0.038, SRMR = 0.039). The Cronbach's alpha coefficient for the total scale was 0.951, and item-total score correlation coefficients ranged from 0.494 to 0.725. These findings demonstrate that the Turkish version of the LIOA is a valid and reliable instrument for assessing loneliness among older adults
