Fungal Pathogens Associated with Crown and Root Rot of Wheat in Central, Eastern, and Southeastern Kazakhstan
(Journal of Fungi, 2022) Bozoğlu, Tuğba; Derviş, Sibel; Imren, Mustafa; Amer, Mohammed; Özdemir, Fatih; Paulitz, Timoth; Morgounov, Alexey; Dababat, Abdelfattah A.; Özer, Göksel
Kazakhstan is the fourteenth largest wheat producer in the world. Despite this fact, there has not been a comprehensive survey of wheat root and crown rot. A quantitative survey was conducted for the purpose of establishing the distribution of fungi associated with root and crown rot on wheat (Triticum spp.). During the 2019 growing season, samples were taken from the affected plants’ roots and stem bases. A total of 1221 fungal isolates were acquired from 65 sites across the central (Karagandy region), eastern (East Kazakhstan region), and southeastern (Almaty region) parts of the country and identified using morphological and molecular tools. The internal transcribed spacer (ITS), translation elongation factor 1-alpha (EF1-α), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) sequences were successfully used to identify the species of fungal isolates. It was found that Bipolaris sorokiniana (44.80%) and Fusarium acuminatum (20.39%) were the most predominant fungal species isolated, which were present in 86.15 and 66.15% of the fields surveyed, respectively, followed by F. equiseti (10.16%), Curvularia spicifera (7.62%), F. culmorum (4.75%), F. oxysporum (4.10%), F. redolens (2.38%), Rhizoctonia solani AG2-1 (1.06%), Nigrospora oryzae (0.98%), C. inaequalis (0.90%), F. pseudograminearum (0.74%), F. flocciferum (0.74%), Macrophomina phaseolina (0.66%), F. cf. incarnatum (0.33%), Fusarium sp. (0.25%), and F. torulosum (0.16%). A total of 74 isolates representing 16 species were tested via inoculation tests on the susceptible Triticum aestivum cv. Seri 82 and the results revealed that F. culmorum and F. pseudograminearum, B. sorokiniana, Fusarium sp., R. solani, F. redolens, C. spicifera, C. inaequalis, and N. oryzae were virulent, whereas others were non-pathogenic. The findings of this investigation demonstrate the presence of a diverse spectrum of pathogenic fungal species relevant to wheat crown and root rot in Kazakhstan. To the best of our knowledge, this is the first report of F. pseudograminearum, Fusarium sp., C. spicifera, and C. inaequalis as pathogens on wheat in Kazakhstan.

(Galenos Publ House, 2023) Bozaci, Ayse Ergul; Goksoy, Emine; Unal, Aysel Tekmenuray; Albayrak, Hatice Mutlu; Tas, Ibrahim; Kanar, Berat; Kose, Melis
Aim: Urea cycle disorders (UCD) still have poor neurological outcomes despite early diagnosis and treatment. We aimed to present the neurological outcomes of UCD patients and to determine the main simple and accessible factors affecting these outcomes. Materials and Metkods: This was a descriptive cross-sectional study conducted in two pediatric metabolism centers on 29 patients from 25 unrelated families who were diagnosed and followed with UCD based on clinical presentation, neurological parameters, biochemical measurements, and molecular analysis.Results: Within the study population, the most common diagnosis was argininosuccinate synthase deficiency in 13 (44.82%) patients, followed by N-acetylglutamate synthase deficiency in five patients (17.24%), ornithine transcarbamylase deficiency in four patients (13.79%), arginase 1 deficiency in three patients (10.34%), carbamoyl phosphate synthase 1 deficiency in three patients (10.34%), and argininosuccinate lyase deficiency in one patient (3.44%). Peak ammonia levels were observed to be significantly higher in those patients with delayed milestones and patients who had Denver II <-2 standard deviation score results (p=0.032, p=0.026). Effect sizes were large in both groups. Delayed milestones were noted in 17 (94.4%) of the cases with peak ammonia >500 mu mol/L (n=18). Those patients with abnormal neurological parameters had a significantly higher mean number of hyperammonemic episodes per year. Extracorporeal detoxification was given to eight patients, in combination with therapeutic hypothermia in two patients. Rapid regression was observed in brain edema in those who underwent therapeutic hypothermia.Conclusion: Our study emphasizes the effect of peak ammonia levels and the frequency of hyperammonemic episodes on neurological outcomes. There were still poor neurocognitive outcomes despite extracorporeal detoxification. This highlights the need to reassess current treatment strategies, including the threshold for starting extracorporeal detoxification if ammonia levels exceed 500 mu mol/L. The use of therapeutic hypothermia by experienced teams may be promising due to its brain edema-reducing effects.

(Galenos Publ House, 2025) Kolukcu, Vildan; Bala, Mehtap Gurler; Sahin, Ahmet Tugrul; Genc, Ali; Unsal, Velid; Firat, Fatih; Gurpinar, Ahmer Burak
Objective: We aimed to evaluate the effectiveness of sugammadex on renal tissue for against ischemia-reperfusion injury. Methods: Twenty-one Wistar albino strain female rats were divided into three groups. The first group functioned as the control cohort for comparison. In Groups 2 and 3, a renal ischemia-reperfusion model was established. Moreover, following the cessation of ischemia, the rats in Group 3 were intravenously administered sugammadex at a dose of 4 mg kg-1. Blood and tissue samples were subsequently collected for analysis. Results: Biochemical analyses revealed a notable increase in the enzymatic activities of glutathione peroxidase and superoxide dismutase in Group 3 relative to Group 2 (P < 0.001 and P=0.015, respectively). Additionally, the concentration of malondialdehyde was found to be significantly reduced in Group 3 relative to Group 2 (P=0.004). Group 3 exhibited a substantial decrease in tumor necrosis factor-alpha, interleukin 6, and interleukin 1 beta levels when compared to Group 2 (P=0.021, P=0.006, and P=0.016 respectively). Group 2 exhibited the highest concentrations of neutrophil gelatinase-associated lipocalin and kidney injury molecule-1 (P < 0.001 and P=0.015, respectively). Similarly, the histopathologic tissue damage was the most prominent in Group 2 (P < 0.001). Conclusion: Sugammadex plays a protective role against ischaemia-reperfusion injury in renal tissue.
Sectarian Diplomacy and the Transformation of Ottoman Statecraft: Yâsincizâde Abdülvehhâb Efendi's Embassy to Qajar Iran (1810-1813)
(MDPI, 2025) Tan, Hasan
At the beginning of the 19th century, Ottoman-Iranian relations entered a new diplomatic phase shaped by Russia's expansion in the Caucasus and Britain's growing influence in the Persian Gulf. This shared perception of external threats led to the establishment of a more structured and representative diplomatic framework between the two empires. This study examines the embassy of Y & acirc;sinciz & acirc;de Abd & uuml;lvehh & acirc;b Efendi, who was appointed as Ottoman ambassador to Iran between 1810 and 1813, in the context of a shifting diplomatic mindset. Y & acirc;sinciz & acirc;de's mission is analyzed not merely as a temporary diplomatic engagement, but as a form of ideological, sectarian, and cultural representation by a figure from the ulema class. Based on archival sources, the study reveals that his diplomatic reports and observations provided critical input to the central administration, contributing to the development of more institutionalized and long-term strategies in Ottoman policy toward Iran. By focusing on the transitional character of his embassy, the paper reassesses the evolving role of religious scholars in Ottoman foreign relations and situates this case between the classical sefaretn & acirc;me tradition and emerging modern diplomatic practices.
The Relationship Between Mothers' Optimism and Children's Anxiety: The Mediating Role of Mothers' Psychological Resilience
(Springer, 2025) Polat, Pinar
This study aimed to investigate the relationships between mothers' optimism, psychological resilience, and children's anxiety, focusing on the mediating role of psychological resilience in T & uuml;rkiye. Using a cross-sectional design, data were collected from 394 mothers with children aged 4-6 through an online survey. Confirmatory factor analysis and structural equation modeling were used to analyze the data. The findings indicated a positive association between mothers' optimism and psychological resilience, and a negative association between psychological resilience and children's anxiety levels. Moreover, psychological resilience served as a mediator, indicating that mothers' optimism indirectly reduced children's anxiety by increasing psychological resilience. These findings highlight the protective role of maternal resilience in reducing children's anxiety and suggest that interventions aimed at strengthening mothers' resilience may contribute to improving children's emotional well-being.

Roles of Loneliness and Life Satisfaction in the Relationship Between Perceived Friend Social Support, Positive Feelings About the Future and Loss of Motivation
(Elsevier, 2025) Aslan, Yavuz; Kocak, Orhan; Kaya, Aysel Basmaci; Alkhulayfi, Abdulmohsen Mohammed Abdullah; Gomez Salgado, Juan; Yildirim, Murat
Purpose: University students often face psychological challenges, particularly loneliness and hopelessness, which are exacerbated by factors such as limited social interactions, economic uncertainty, lack of employment opportunities, and the increasing prevalence of online education. This study aims to investigate the relationships among perceived friend social support, loneliness, life satisfaction, and the sub-dimensions of hopelessness, which are positive feelings about the future and loss of motivation. Design/methodology/approach: This cross-sectional quantitative study was conducted with 420 university students who completed a series of self-reported measures, including the Multidimensional Perceived Social Support Scale, the UCLA Loneliness Scale, the Satisfaction with Life Scale, and the Beck Hopelessness Scale. Findings: The findings revealed that perceived friend social support was positively associated with life satisfaction and positive future feelings and negatively associated with loneliness and loss of motivation. Both loneliness and life satisfaction individually and serially mediated the relationships between social support and the dimensions of hopelessness. Conclusion: These results highlight the crucial role of friend-based social support in alleviating loneliness and improving life satisfaction, thereby fostering optimism and preventing motivational decline among students. The findings provide valuable insights for designing interventions to enhance emotional well-being and psychological resilience among university populations.

(ELSEVIER SCI LTD, 2019) Ozdemir, Sadin; Mohamedsaid, Siham Abdullah; Kilinc, Ersin; Soylak, Mustafa
A new bio-MSPE sorbent based on the use of C. micaceus and gamma-Fe2O3 magnetic nanoparticle was prepared for the preconcentrations of Co(II) and Hg(II). Critical parameters including pH, flow rate, quantity of C. micaceus, quantity of gamma-Fe2O3 magnetic nanoparticle, eluent (type, concentration and volume), sample volume, and foreign ions were examined. Surface structure and variations after interaction with Co(II) and Hg(II) of bio-MSPE sorbent were investigated by FT-IR, SEM, and EDX. The impact of bio-MSPE column reusage was also tested. The biosorption capacities were determined as 24.7 mg g(-1) and 26.2 mg g(-1), respectively for Co(II) and Hg(II). Certified reference materials were utilized to find out the accuracy of the prepared bio-MSPE method. This novel bio-MSPE method was accomplished by being applied to real food and water samples. In particular, it will be possible to make use of C. micaceus as new alternatives, in environmental biotechnology applications.

(Wiley Online Library, 2021) Kutluay, Sinan; Horoz, Sabit; Şahin, Ömer; Ekinci, Arzu
Herein, magnetic Fe3O4@SiO2 nanomaterial functionalized with amine groups (Fe3O4@SiO2@IPA) doped with manganese (Mn) was prepared, characterized and used for solar cell application. Fe3O4@SiO2@IPA-Mn was prepared via the co-precipitation and sol-gel techniques. Energy-dispersive X-ray (EDX), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) measurements were performed to examine the structure of Fe3O4, Fe3O4@SiO2, Fe3O4@SiO2@IPA and Fe3O4@SiO2@IPA-Mn. General morphology and textural properties of the prepared magnetic nanomaterials were clarified by Brunauer-Emmett-Teller (BET) and scanning electron microscopy (SEM). In addition, Ultraviolet-visible (UV-Vis) spectroscopy and thermal gravimetric analysis (TGA) were used to have a knowledge about the energy band gap and thermal behavior of the prepared magnetic nanomaterials. The energy band gap of Fe3O4@SiO2@IPA with spinel structure was determined as approximately 2.48 eV. It was understood that Fe3O4, Fe3O4@SiO2 and Fe3O4@SiO2@IPA showed type IV-H3 hysteresis cycle according to IUPAC. From the BET data, it was determined that the specific surface areas of Fe3O4, Fe3O4@SiO2 and Fe3O4@SiO2@IPA were 60.85, 28.99 and 40.41 m(2)/g, respectively. The pore size distributions of Fe3O4, Fe3O4@SiO2 and Fe3O4@SiO2@IPA were calculated as 8.55, 1.53 and 1.70 nm, respectively, by the BJH method. Also, it was observed that the dominant pore widths of Fe3O4, Fe3O4@SiO2 and Fe3O4@SiO2@IPA were calculated similar to 5.58, similar to 0.88 and similar to 17.92 nm, respectively, by the DFT method. Au/CuO/Fe3O4@SiO2@IPA-Mn/ZnO/SnO2: F solar cell device was created using existing Fe3O4@SiO2@IPA-Mn as a buffer layer. The power conversion efficiency (%) of Fe3O4@SiO2@IPA-Mn based solar cell device was calculated as 2.054. This finding suggest that Fe3O4@SiO2@IPA-Mn can be used as a promising sensitizer in solar cell technology. Moreover, in this study, the effectiveness of the modification of manganese (one of the transition metals, which is cheap and easily available) with magnetic nanomaterials in the use of solar cell technology was demonstrated for the first time.

Determining the Knowledge Levels and Opinions of Athletes Who Is Age Under-16 in Different Branches About Doping and Ergogenic Aids
(Mattioli 1885, 2020) Ceylan, Abdil; Calik, Febmi; Geri, Serdar; Sen, Murat; Ece, Cuma; Sumer, Mebmet
Study Objectives: The study aimed to evaluate the knowledge levels and opinions of athletes under 16 years of age about doping and ergogenic aids in different branches. The fact that there are no studies in the literature on the knowledge and opinions of athletes under the age of 16 on doping and ergogenic aids has encouraged us to the study. Methods: The sample of the study consists of 392 athletes under 16 years of age in different sports branches. In the study, a questionnaire consisting of 5 likert and 26 questions about doping substances and ergogenic aids was applied to the athletes by Eroz (2007). Results: As a result of the analysis of the obtained findings with the Chi-square test, it was determined that as the age of the athletes increased, the belief that the athlete used doping increased with the fear of losing. It has been determined that as the family income increases, the tendency to try every way to be successful does not decrease significantly, and athletes with low family income are more willing to try every way to be successful. As the education of the athlete's parents increased, the belief that the use of doping harmed the Fair-Play spirit in sports and that doping leads to unfair competition has been increased. Conclusion: The study revealed that there is a need to reinforce the doping knowledge of athletes. It has been concluded that certain socio-economic conditions are determinants in the use of doping by athletes and that they shape their tendency towards doping. Therefore, it is thought that the trainers, managers, athlete families and athletes about the negative effects of doping use on athlete health is of great importance.

Violence in Zeki Demirkubuz's Cinema: Innocence and Destiny
(ANKARA UNIV, FAC COMMUNICATION, 2015) Aytekin, Pelin Erdal
This article focuses on how Zeki Demirkubuz approaches to the phenomenon of violence in his movies. The study aims at making the world transformed by violence comprehensible, rather than using the film narrative only as a means to discover the concept of violence. The phenomena of violence in Innocence (1997), in which Demirkubuz views violence as "a way of human nature", and Destiny (2006) are subjected to detailed film analysis The cinematographic language created by Demirkubuz in the above mentioned movies is examined through auteur analysis. The diversifying appearances of violence in Demirkubuz's movies are revealed by an analysis informed by mise-en-scene criticism. Thus, the article suggests that Demirkubuz, is one of the significant directors of Turkish cinema who make violence visible through the atmosphere he creates with his characters. It is observed that Demirkubuz's embittered and resigned characters unfold the phenomenon of violence in the movies analysed.

Decarbonizing Buildings With Autoclaved Aerated Concrete (AAC): Climate-Specific Meta-Analysis of Global Performance
(Taylor & Francis Ltd, 2025) Azhar, Jasim; Aydin, Serdar; Zami, Mohammad Sharif
The building sector, which accounts for 40% of global energy consumption and 36% of CO2 emissions, requires immediate access to scalable low-carbon materials. The theoretical thermal advantages of Autoclaved Aerated Concrete (AAC) remain incomplete because field performance reports show inconsistent results between 15% and 50% energy savings, and multiple unaddressed implementation challenges have prevented its strategic adoption. The systematic review used worldwide climate-based empirical data to resolve existing performance discrepancies and develop practical implementation strategies. The meta-analysis of 12 studies comprising 847 dwelling units, assessed using CASP and ROBINS-I quality tools, showed that energy savings depend on climate zone: hot-arid zones achieving 48.3% (95% CI: 42.1-54.5%), cold-temperate zones 32.7% (27.3-38.1%), and hot-humid zones 28.4% (22.9-33.9%). The strongest predictor of performance was cooling degree days (beta = 0.0089, p < 0.001), while implementation quality explained 26% of performance variation. Economic modelling revealed median payback periods from 4.2 years (hot-arid) to 9.7 years (cold-temperate), with a 78-92% probability of positive lifetime returns. Carbon pricing at $50/tCO(2) reduces payback by 23%. The research develops a climate-oriented analytical system that analyses performance variations to help designers and policymakers achieve maximum AAC decarbonization results by combining environmental data with system information and financial metrics.

The Effectiveness of HALP Score in Predicting Mortality in Non-ST Myocardial Infarction Patients
(Lippincott Williams and Wilkins, 2025) Kiliç, R.; Guzel, T.; Aktan, A.; Güzel, H.; Kaya, A.F.; Çankaya, Y.
Background: The HALP score, measured based on hemoglobin, albumin, lymphocyte, and platelet levels, is regarded as a novel scoring system that indicates the status of systemic inflammation and nutritional health. Our study aimed to evaluate the relationship between HALP score and prognosis in non-ST-elevation myocardial infarction (NSTEMI) patients. Methods Between 1 January 2020 and 1 January 2022, 568 consecutive patients diagnosed with NSTEMI from a single center were included in the study retrospectively. The patients were divided into two equal groups according to the median HALP cutoff value of 44.05. Patients were followed for at least 1 year from the date of admission. Results The average age of the patients was 62.3±10.6 years and 43.7% were female. In-hospital and 1-year mortality were found to be significantly higher in the group with low HALP scores (6.0 vs. 2.1%, P=0.019 and 22.5 vs. 9.9%, P<0.001, respectively). In receiver operating characteristic curve analysis, a cutoff level of 34.6 of the HALP score predicted 1-year mortality with 71% sensitivity and 65% specificity (area under the curve: 0.707, 95% confidence interval: 0.651-0.762, P<0.001). In Kaplan-Meier analysis, higher mortality rates were observed over time in the group with lower HALP scores (log-rank test=16.767, P<0.001). In Cox regression analysis, the HALP score was found to be an independent predictor of 1-year mortality (odds ratio: 0.969, 95% confidence interval: 0.958-0.981, P<0.001). Conclusion We found that a low HALP score could predict in-hospital and 1-year mortality in patients admitted to the hospital with a diagnosis of NSTEMI. © © 2024 Wolters Kluwer Health, Inc.

(Andrologia, 2021) Unsal, Velid; Kölükçü, Engin; S. Parlaktaş, Bekir; Kölükçü, Vildan; Fırat, Fatih; Deresoy, Faik A.; Katar, Muzaffer; Kuyucu, Yunus Emre
The study aimed to investigate the effects of dexmedetomidine against ischaemia-reperfusion injury occurring after priapism in a model of induced-priapism in rats. A total of 18 male rats were randomised into three groups. Group 1 was the control group. A priapism model was performed rats in Group 2 and then ischaemia-reperfusion injury was evaluated. Group 3 had similar procedures to the rats in Group 2. Rats in Group 3 additionally had 100 μg/kg dexmedetomidine administered intraperitoneally immediately after reperfusion. Blood and tissue samples were analysed. Biochemical analysis of blood samples revealed a decrease in the levels of the pro-inflammatory cytokines including interleukin-1 beta (IL-1 Beta), interleukin-6 (IL-6), and tumour necrosis factor-alpha (TNF-alpha) in Group 3 compared to Group 2 (p:.04, p:.009 and p:.009, respectively). Similarly, the highest malondialdehyde (MDA) level was in Group 2 (p:.002). The levels of antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities were significantly higher in Group 3 than that of Group 2 (p:.037 and p:.045, respectively). Direct microscopic examinations revealed positive changes in desquamation, oedema, inflammation and vasocongestion scores in Group 3 compared to Group 2 (p:.007, p:.008, p:.007 and p:.006, respectively). Dexmedetomidine has a protective effect against ischaemia-reperfusion injury in penile tissue.

(WALTER DE GRUYTER GMBH, 2017) Kacar, Semra; Bashan, Mehmet
Objective: The aim of the study was to investigate quantitative and qualitative fatty acid profiles of the gonad and liver tissue of female Mastacembelus mastacembelus (spiny eel). Methods: Total lipids were extracted with 5 mL of chloroform-methanol (2:1 v/v). Samples containing gonad and liver lipid were transesterified with acidified methanol. The fatty acid methyl esters were extracted with hexane. Fatty acids were detected by gas chromatography (GC). Results: The major saturated fatty acids (SFAs) were myristic acid (C14:0), palmitic acid (C16:0) and stearic acid (C18:0) in both gonad and liver tissue. Oleic acid (C18:1 omega-9) and palmitoleic acid (C16:1 omega-7) were the prominent monounsaturated fatty acid (MUFA). The dominant polyunsaturated fatty acids (PUFAs) were linoleic acid (LA, C18:2 omega-6), arachidonic acid (AA, C20:4 omega-6), docosapentaenoic acid (C22:5 omega-3) and docoesahexaenoic acid (DHA, C22:6 omega-3). The ratio of omega-3/omega-6 ranged from 1.55 to 3.44 and 1.18 to 2.71 in the gonad and liver tissue, respectively. Conclusion: The findings of this study will be useful for understanding the seasonal distribution of fatty acid composition in the liver and gonad of spiny eel.

First report of needle blight of blue spruce (Picea pungens) caused by Neoscytalidium dimidiatum in Turkey
(SpringerLink, 2023) Derviş, Sibel; Türkölmez, Şahimerdan; Güney, İnci Güler; Alkan, Mehtap; Özer, Göksel
The blue spruce (Picea pungens Engelm.) is an exotic conifer species widely used for decorative purposes in landscaping and private gardens. In 2020, 60% of forty blue spruce trees between 20 and 25 years old planted in front of buildings in Kavaklıdere, Ankara, displayed needle blight symptoms. Needles on the lower and interior crown closest to the trunk were infected from the bottoms of branches. They showed a brown-colored or burned appearance before dropping off, starting from their tips, resulting in up to a 65% reduction of the canopy. On the surface of infected tissues, a black-colored fungal mass was observed. Fungal colonies isolated from twenty symptomatic branches and needles were initially dark gray and became black within 4 to 7 days. Zero- to one-septate dark brown conidia (4.6 to 9.8 × 3.6 to 7.5 μm) formed in arthric chains were disarticulating and cylindrical-truncate to rod-shaped, oblong, ellipsoidal, doliiform, or globose, consistent with the description of Neoscytalidium spp. (Crous et al. 2006). The internal transcribed spacer, translation elongation factor 1-α, and β-tubulin loci of a randomly selected isolate (Nd_Pp01) were sequenced using the primers ITS1/4, EF1-728 F/986R, and Bt2a/Bt2b and deposited in GenBank under the accession numbers OK643641, OK666381, and OK666382, respectively. The sequences had 99.77–100% nucleotide identity with those of the type specimen of N. dimidiatum, CBS 145.78. Phylogenetic analysis with concatenated sequences further confirmed the identification. The isolate was deposited in the Bolu Abant Izzet Baysal University Culture Collection with accession number BAIBU-179. A pathogenicity test was conducted with ten 1-year-old P. pungens plants by spraying a conidial suspension (105 conidia/ml) of the isolate Nd_Pp01 onto the needles (Türkölmez et al. 2019). Five seedlings sprayed with sterile water were used as controls. All plants were placed in a growth chamber at 28°C with 70% RH. Spray-inoculated needles initially showed yellow spots within two weeks and turned brown six weeks after inoculation, whereas the controls remained symptom-free. The pathogen was re-isolated from the inoculated needles but not from controls. To our knowledge, this is the first report of N. dimidiatum causing needle blight on P. pungens in Turkey and worldwide (Farr and Rossman 2023).
