    GĂŒnĂŒmĂŒzde sosyal medya krizlerin baƟladığı ve krizlerin çözĂŒldĂŒÄŸĂŒ bir mecra olarak karĆŸÄ±mıza çıkmaktadır. Kullanıcı sayısı her geçen gĂŒn artan sosyal medyanın gĂŒcĂŒne kayıtsız kalamayan devlet kurumları da sosyal medyadan faydalanmakta, CumhurbaƟkanlığı ve Bakanlar Kurulu ĂŒyeleri, kriz dönemlerinde, krizi etkili bir biçimde yönetebilmek amacıyla da sosyal medyadan istifade etmektedirler. Bu çalÄ±ĆŸma, TĂŒrkiye tarihi açısından önemli bir kriz dönemi olan 15 Temmuz darbe giriƟimi sonrası ilan edilen ilk OHAL sĂŒrecini kapsamaktadır. ÇalÄ±ĆŸma kapsamında, örneklem olarak kriz dönemlerinde en yaygın olarak kullanılan sosyal medya ağlarından Twitter seçilmiƟtir. CumhurbaƟkanı ve Bakanlar Kurulu ĂŒyelerinin, ilk OHAL dönemini kapsayan, 20 Temmuz-20 Ekim tarihleri arasında Twitter’ı, ne sıklıkla, hangi amaçlar doğrultusunda kullandıkları nitel ve nicel içerik analizi yöntemiyle incelenmiƟtir. Bu bağlamda kriz dönemlerinde CumhurbaƟkanı ve Bakanlar Kurulu ĂŒyelerinin Twitter’ı aktif olarak kullandıkları gözlemlenmiƟtir. Yapılan paylaĆŸÄ±mlarla takipçiler; yanıt, Retweet (yeniden tweetleme) ve favorilerle cevap vererek yĂŒksek oranda CumhurbaƟkanı ve Bakanlar Kurulu ĂŒyeleriyle etkileƟime girmiƟlerdir. CumhurbaƟkanı ve Bakanlar Kurulu ĂŒyelerinin paylaĆŸÄ±mlarında kriz yönetimi baƟlığı öne çıktığı kadar, itibar yönetimine de önem verdikleri görĂŒlmĂŒĆŸtĂŒr. CumhurbaƟkanı ve Bakanlar Kurulu ĂŒyelerinin, TĂŒrkçe paylaĆŸÄ±mlarına kıyasla daha dĂŒĆŸĂŒk oranda yaptıkları yabancı dildeki paylaĆŸÄ±mlarıyla da uluslararası alanda kriz ve itibar yönetimine katkı sağladığı dĂŒĆŸĂŒnĂŒlmektedir

    INTRODUCTION: The main factors in the development of ST-segment elevation myocardial infarction (STEMI) are inflammatory processes and pathophysiological changes due to oxidant stress. The aim of this study is to evaluate the association of prevalent STEMI with markers of inflammatory and oxidative stress. The platelet to monocyte ratio (PMR) was evaluated as a new hematological inflammatory marker.   MATERIAL AND METHODS: The study is a retrospective observational study conducted in the emergency department between January 2018 and January 2019. In the study, all patients who were diagnosed with STEMI were considered in the study group. Evaluations of inflammatory and oxidant stress markers, PMR value of STEMI patients were performed.   RESULTS: Neutrophil to lymphocyte ratio (NLR) value of 5.63 (3.35–7.84), Monocyte count to high-density lipoprotein cholesterol ratio (MHR) value of 16.10 (12.73–19.52), gamma-glutamyl transferase (GGT) value of 31.00 (21–39) and CRP value of 5.10 (2.77–9.34) were significantly higher in STEMI cases (p < 0.005). The lymphocyte to monocyte ratio (LMR) value of 2.57 (2.00–3.61) and the PMR value of 24.52 ± 7.60 in STEMI cases were significantly lower (p < 0.001, p = 0.014).   CONCLUSIONS: In STEMI patients NLR, GGT, and MHR rates increase significantly and LMR decreases. PMR values were also lower in STEMI cases. This shows us that PMR is a new determinant that can be used in inflammatory events. However, none of these inflammatory markers and oxidant stress markers can be used as diagnostic tests, rather they should be considered as surrogate markers for disease

    In this study, the mediating and moderating role of Facebook addiction in the relationship between school burnout, and school engagement was investigated. The study group comprised of 283 students continuing to 6th, 7th, 8th and 9th grades. The data were collected by School Burnout Inventory, School Engagement Scale and Facebook Addiction Scale. As a result of the correlation analysis, a significant positive correlation was found between school burnout and Facebook addiction. Also, school engagement was negatively related to school burnout and Facebook addiction. The structural equation model findings indicated that Facebook addiction had a partial mediating role between school burnout and school engagement. The results of the bootstrap analysis supported the significance of the partial mediating role. Besides, as a result of the regression analysis, it was found that Facebook addiction had a differentiating role in the relationship between burnout and school engagement. Research findings are discussed in light of the literature. It is recommended to carry out studies to prevent social media addiction and to enhance conscious technology use. These studies are considered to contribute to reduce school burnout of the students and increase their school engagement.Bu çalÄ±ĆŸmada Facebook bağımlılığının okul tĂŒkenmiƟliği ve okul bağlılığı arasındaki iliƟkide aracı ve farklılaƟtırıcı rolĂŒ araƟtırılmÄ±ĆŸtır.

    This work was supported by grants from Cankiri Karatekin University and the State Planning Organization, Turkey (Project No: 2010K120720). The authors would also like to thank Turkish Republic Ministry of Forestry and Water Affairs, General Directorate of Nature Protection and National Parks for permission to collect the mosses Dicranum scoparium and Hypnum cupressiforme from Ilgaz Mountain National Park. Finally, the authors thank Bianka Martinez for grammatical revision of the manuscript.The composition of fatty acids and insecticidal effects was performed for the Turkish mosses Dicranum scoparium, Hypnum cupressiforme, Polytrichastrum formosum, Homalothecium lutescens and the Turkish liverwort Conocephalum conicum. All structures were determined by means of gas chromatography and gas chromatography-mass spectrometry techniques. The determination of fatty acids was done using a simple and mild method that utilized different solvent extractions ranging from nonpolar to polar solvents (hexane, dichloromethane, chloroform, ethyl acetate and methanol, respectively), and the samples were powdered with and without liquid nitrogen. The correlations between the saturated and unsaturated fatty acid contents depending on the solvent polarity and their crushing process by liquid nitrogen were observed. The insecticidal activity of the bryophytes was analyzed by using the methanol, hexane and esterified methanol extracts. The hexane extracts of Polytrichastrum formosum showed the highest insecticidal activity (70.33%) against Sitophilus granarius. Contact toxicity activities of lauric, myristic and palmitic acids besides single dose studies of the solvent extracts were carried out. The highest mortality rate (53.34%) was obtained from the myristic acid among the tested pure fatty acids. The activities of palmitic and lauric acids were 17.75% and 4.32%, respectively

    The antifungal activity of Mentha rotundifolia essential oil, harvested in Setif (Algeria) was evaluated in vitro against a phytopathogenic fungi Fusarium oxysporum, causing damage on tomato. The molecular identification of the strain was based on a comparison (BLAST) of the sequences obtained against a database and was often supplemented by microscopic observations. After quot%253BSANGERquot%253B sequencing of the PCR products, the sequences were received in FASTA format. Analysis of M. rotundifolia essential oil by Gas Chromatography%252FMass Spectrometry method (GC-MS) identified 14 compounds. The 3-Cyclopenten-1-one, 2-hydroxy-3- (3-methyl-2-butenyl) - was the major constituent of this oil with a rate of about 89.09%25. For this activity, we adopted the technique of direct contact on agar. F. oxysporum continued to grow on oil-free media at 1%25 and 0.1%25 (fungistatic effect)%253B also on media with an oil concentration of 0.01%25. While the explants taken from petri dish with essential oil concentration of 2%253B 4 and 10%25 did not grow (fungicidal effect). The very interesting antifungal effect of M. rotundifolia essential oil indicates the potential of this plant species as a source of natural fungicidal material. The present study revealed that this mint exhibited antifungal effect against F. oxysporum which provided a scientific basis for the use of this species as a good source of antifungal compounds. This preliminary work could provide a basis for the determination of sufficient and effective concentrations for in planta studies for the biological control of natural active substances of M. rotundifolia against fungal diseases

    Objective. To assessment the role of preoperative neutrophil-lymphocyte ratio and postoperative lymph node density in predicting prognosis in patients undergoing radical cystectomy for bladder cancer. Material and Methods. Preoperatively, neutrophil and lymphocyte counts as well as neutrophil-lymphocyte ratios were recorded in 201 patients who underwent radical cystectomy for bladder cancer. Patients with an infection were excluded. Based on the pathology reports, the number of positive lymph nodes was divided by the total number of lymph nodes to calculate lymph node density. Results. The mean follow-up duration was months in patients without lymph node involvement and months in those with lymph node involvement (). Median lymph node density was 17% (4–80) in patients with lymph node involvement. There was no difference according to lymph node density lower than 17% and greater than 17% . There was no significant difference between patients with an NLR below or above 2.5 in terms of overall survival (). Pathological T stage was associated with survival (). Conclusion. In patients undergoing RC for bladder cancer, lymph node density and preoperative NLR were not found to be independent predictors of prognosis
