Renewable energy sources, as well as the studies being conducted regarding these energy sources, are becoming increasingly important for our world. In this manuscript, the daily energy production level of a small (15 MW) run-of-river hydropower plant (RRHPP) was estimated using the artificial neural network (ANN) model. In this context, the model utilized both meteorological data and HPP-related data. The input parameters of the artificial neural network included the daily total precipitation, daily mean temperature, daily mean water vapour pressure, daily mean relative humidity, and the daily mean river water elevation at the hydropower plant, while the only output parameter consisted of the total daily energy production. For the ANN, data from the four years between 2017 and 2020 were used for training purposes, while data from the first eight months of 2021 were used for testing purposes. Ten different ANN networks were tested. A comparison of the ANN data with the real data indicated that the model provided satisfying results. The minimum error rate was 0.13%, the maximum error rate was 9.13%, and the mean error rate was 3.13%. Furthermore, six different algorithms were compared with each other. It was observed that the best results were obtained from the Levenberg-Marquardt algorithm.This study demonstrated that the ANN can estimate the daily energy production of a run-of-river HPP with high accuracy and that this model can potentially contribute to studies investigating the potential of renewable energies.

This study was carried out in Osmaniye location of Oil Seed Research Institute in 2020-2021 in order to determine some yield and quality characteristics in second crop cultivation of peanuts with different market types in the Eastern Mediterranean transition zone. Eleven different genotypes of Runner (Georgia Green) Virginia (NC 7, Masal, Halisbey, Wilson, Çom, Brantley, Sultan, Düziçi 1) Spanish (Florispan, Nigeria 1) types of peanut were used in the study. In the study, number of pods per plant, 1st quality pod ratio, pod weight per plant, 100 pod and seed weight, shelling percentage, pod yield, oil content and, protein content parameters were investigated. The number of pods per plant is between 20.8 (Nigeria 1) and 51.4 (Düziçi 1); pod weight per plant varied between between 12.3 g (Nigeria-1) and 64.9 g (Halisbey). It was determined that 100 pod weight and 100 seed weights varied between 66.8-289.0 g and 29.6-106.5 g, respectively. Pod yield varied between 1963 kg ha-1 (Nigeria 1) and 4846 kg ha-1 (Düziçi 1). As a result, it was determined that Düziçi 1 genotype, Brantley and Halisbey cultivars came to the fore in terms of the investigated characteristics in the Eastern Mediterranean Passage zone. In the study, while the second crop peanut variety suitable for the Eastern Mediterranean Transition zone was determined, the varieties to be used as breeding material were also determined.

The purpose of this research; In the 2021-2022 academic year, based on the opinions of the principals working in primary, secondary and high schools in the city center of Tokat, it is aimed to reveal whether the principals have the necessary knowledge and skills for inspection, the problems they encounter in inspection, and the positive and negative aspects of inspection. The data used in the research were collected from a total of 18 people, including 6 primary school principals, 6 secondary school principals and 6 high school principals, selected according to the maximum diversity sampling, working in the central primary, secondary and high school in Tokat province. The data collected with the standardized open-ended interview form developed by the researcher were analyzed and interpreted using the content analysis approach, one of the qualitative data analysis approaches. According to the results of the research, most of the participants argued that it is a correct practice to carry out the supervision by the school principals. The participants stated that the supervision by the school principals puts pressure on the teachers and students, and the teacher-principal relations are negatively affected. It has been concluded that the positive aspects of supervision by school principals are that teachers keep themselves up-to-date on the program and content and contribute positively to their professional development. It was emphasized that the negative aspects of supervision by school principals would damage the developed relations between the supervisor and the supervisor. This situation also emphasized the damage to the institutional balance and school culture, and the psychological pressures that the supervision itself will create on teachers.

Turkish hazel (Corylus colurna L.) is naturally distributed in southeast Europe, Anatolia, the Caucasus and Western Himalayas. In Turkey, there are many isolated populations in the Black Sea, Marmara, Aegean, and Central Anatolian Regions. Many of the small populations in Turkey are endangered. In this study, the morphological and chemical characteristics of Turkish hazelnut fruits collected from seven populations were researched. In this regard, considering the morphological characteristics of fruits and kernels, significant differences were observed between the populations. Length, width, thickness, and weight averages were 15.98 mm, 15.38 mm, 12.00 mm and 1.4651 g in the fruits, and 13.03 mm, 11.22 mm, 7.64 mm and 0.5047 g in the kernels, respectively. The average shell thickness was 1.92 mm, shell weight was 0.9604 g, and kernel ratio was 35.16%. Statistically significant differences were found out between the populations whose chemical contents were analyzed. As a result of the analysis, the average fat content, protein, starch, and ash were 64.1%, 15.9%, 10.2 g, and 2.5%, respectively. According to the averages in the obtained fatty acids, the main fatty acids were oleic acid (79.53%), linoleic acid (11.34%), palmitic acid (5.68%), and stearic acid (2.03%), while the rest of other oils were found in trace amounts. Overall, our results suggest that the information relating to morphological and chemical characteristics of Turkish hazelnut can be useful for discriminating among populations.

Objectives: The purpose of this study was to investigate the potential association between the presence of a fragmented QRS (fQRS) pattern on electrocardiogram (ECG) and prognostic outcomes in patients with heart failure (HF). Methods: In the study, 238 patients with a left ventricular ejection fraction of less than 35% were included. The presence of fQRS pattern on ECG was analyzed in all patients. Patients were divided into two groups based on the presence or absence of fQRS on ECG. The primary clinical end points were all-cause mortality and rehospitalization. Results: Baseline demographic characteristics were comparable between the groups. Patients with fQRS had a higher frequency of coronary artery disease and atrial fibrillation (72 (76%) vs 90 (62%), (p = 0.023; 27 (29%) vs 25 (17%), (p = 0.038, respectively). Additionally, patients with fQRS had a higher rate of mortality and rehospitalization during the 5-year follow-up period compared to patients without fQRS. (30 (32%) / 28 (19%), (p = 0.028; 56 (60%) / 50 (35%), p < 0.001, respectively). Multivariable logistic regression analysis revealed that the presence of fQRS was independently associated with mortality and rehospitalization ((p = 0.02 and p < 0.001, respectively). Conclusions: The results of this study suggest that the presence of fQRS on ECG in patients with HF is independently related to a higher risk of mortality and hospitalization. Therefore, the presence of fQRS may be a useful indicator of poor prognosis in these patients.

Günümüz temel problemlerinden biri olan küresel ısınma beraberinde iklim değişikliğini de getirmektedir. Atmosfer ve dünya arasındaki enerji değişimini etkilediği için Yer Yüzeyi Sıcaklığı (YYS) iklimin en önemli parametrelerinden birisidir. Bu nedenle büyük ve küçük ölçekli çalışmalar yapılırken YYS, göz önünde bulundurulması gerekmektedir. Uzaktan algılama verilerinin işlenmesi, analiz edilmesi ve değerlendirilmesi için birçok sistem geliştirilmiştir. Bunlardan birisi web tabanlı sistem olan Google Earth Engine (GEE)’dir. GEE arayüzü, farklı çözünürlüklere sahip uydu verilerinin hızlı bir biçimde değerlendirilmesini ve analiz edilmesini sağlar. Bu çalışmada 7 farklı istasyona ait toplamda 14 Landsat-8 uydu görüntüsü kullanılarak GEE platformunda kodlar yardımıyla 4 farklı metot ile yüzey sıcaklıkları elde edilmiştir. Elde edilen sıcaklıklar istasyondan ölçülen yakın hava sıcaklığı ile karşılaştırılarak tüm metotlar için Karesel Ortalama Hata (KOH) ve korelasyon değerleri hesaplanmıştır. Son dönemde çalışma konusu olarak artış gösteren YYS, GEE gibi kullanımı oldukça basit bir platformda ayrıca uydu görüntüsü indirmeye gerek kalmadan hızlı, kolay ve kısa bir sürede elde edilebileceği ortaya konulmuştur.

In this study, four stages were used to create brand-new p-tert-butyl-calix [4] arene Schiff base derivatives. First, p-tert-butyl-phenol and formaldehyde are reacted to create p-tert-butyl-calix [4] arene (1). In the following step, methyl bromoacetate and p-ter-butyl-calix [4] arene (1) were combined with acetone and reflux to create the p-tert-butyl-calix [4] arene diester complex (2). The third step involves reacting the diester compound (2) and hydrazine hydrate to create the p-tert-butyl-calix [4] arene hydrazinamide molecule (3). In the final stage, calix [4] arene Schiff base derivatives (4a-d) were produced in good yields by combining compound (3), p-tert-butyl-calix [4] arene hydrazinamide, and various aldehyde derivatives with reflux in EtOH. Through the use of 1H-NMR, 13C-NMR, infrared spectroscopy, and elemental analysis, the structures of produced compounds were verified. Four distinct cancer lines are linked to the antitumor activity of synthetic chemicals. (HT-29, a human colon cancer cell line, PC-3, a human prostate cancer cell line, C6, a rat glioma cell line and MCF-7, a human breast cancer cell line). Weak antitumor activity was seen in synthetic substances. However, only compound 4b was found to have potential efficacy against C6 and HT-29. It is clear that compound 4b, which has a nitro substitute on the phenyl ring, draws attention due to its increased activity.

The information on the websites of 169 health facilities that were evaluated within the scope of the research and received the relevant authorization certificate from the Ministry of Health was examined by content analysis method. In the evaluation, 23 criteria obtained from the literature and five groups consisting of these criteria, namely communication, facilitation, institutional information, personnel information, accommodation, and health service information were used. As a result of analyzes, it was found that the websites of health facilities mostly included the criteria of in-site search feature, vision and mission, and institutional information content. It has been concluded that the websites of tertiary health facilities mostly included the mentioned criteria, and in terms of groups, almost all the facilities mostly included the corporate information group in their websites. Other prominent results are that the criteria of in-site search feature, a foreign language option and social networking links differed by the region and the type of health facility. According to the results of the study, recommendations were made for practitioners and future research.

Extracorporeal cardiopulmonary resuscitation (ECPR) is the rapid deployment of venoarterial extracorporeal membrane oxygenation (ECMO) during active cardiopulmonary resuscitation or in patients with intermittent return of spontaneous circulation. This study aimed to describe the demographic characteristics and outcomes of patients undergoing ECPR to identify survival-associated factors.The study was conducted in an extracorporeal life support centre of a tertiary hospital in Turkey and included all patients who underwent ECPR for in-hospital cardiac arrest between April 2013 and June 2021. Complications included bleeding, neurological injury, renal failure, hepatic failure, limb ischemia and bloodstream infections. The primary outcomes were survival of ECMO and survival to discharge. Neurological outcomes were assessed using the Pediatric Cerebral Performance Category Scale for children and the Category of Cerebral Performance Scale for adults.The study included 26 patients (24 paediatric, 2 adults), 22 (85%) of them had cardiac pathology. Bleeding was the most common complication. Twelve (46%) patients survived ECMO, 9 (35%) survived to discharge. Sex, age, primary diagnosis, cardiac arrest rhythm and ECMO duration were not significantly associated with the primary outcomes. Bleeding, neurological injury and renal failure were associated with poorer survival to discharge. The neurological outcomes of all survivors to discharge were good.ECPR is not commonly accessible. Sharing the experience of the few treating centres to date is crucial to accumulating sufficient knowledge about its efficiency and raising clinician awareness. This limited single-centre experience demonstrated the utility of ECPR.

Pneumopericardium is the presence of air in the pericardial sac. Pneumopericardium after pericardiocentesis has been rarely reported in the literature. In the present case, we report a patient who presented with tamponade physiology during COVID-19 and developed pneumopericardium after emergency pericardiocentesis. Immediate recognition and treatment are crucial and chest X-ray, thorax computerized tomography and transthoracic echocardiography are used for diagnosis.

Objective: We aimed to discuss our unit’s experience performing left ventriculotomies on children. Methods: Between 2000 and 2022, we identified paediatric patients who required left ventriculotomy. Relevant information was gathered retrospectively. Results: There were eight patients who underwent surgical procedure including left ventriculotomy. The range of weight and age was between 4.5 and 50 kg and 5 months to 17 years, respectively. Left ventriculotomy was primarily performed for the excision of cardiac masses in all but one who had pseudoaneurysm repair. There were no deaths that occurred early or late. Pre-operative and post-operative ejection fractions and fractional shortening values were comparable. There was no arrhythmia detected post-operatively. Conclusions: We conclude that an apical left ventriculotomy does not compromise the function of the left ventricle, even in young infants. In selected patients, it may be used safely for surgical access to the left ventricle.

In the test group, the graft was stabilized and the donor site was coated with cyanoacrylate. In the control group, 6/0 polyvinylidene fluoride sutures were used for stabilization, while the donor site was left untreated. Variables including re-epithelization, post-operative complications, pain, bleeding and quality of life at recipient site, and color match, graft dimensions at donor site were assessed for up to 6 months. Results: Twenty-three individuals completed the study. No differences were observed in any variable between groups except horizontal dimension loss of the graft, which was more abundant in the cyanoacrylate group at six months (p>0.05, p

Hayatımızın her alanına giren elektronik ve bilgisayar teknolojilerinden diğer tüm sektörlerde olduğu gibi inşaat sektöründe de İş Sağlığı ve Güvenliği (İSG) ’nin sağlanmasına yönelik yararlanma çabaları, son yıllarda başta gelişmiş ülkelerde olmak üzere tüm dünyada artış göstermektedir. İnşaat sektörü, ülkemizde iş kazası sonucu yaralanma ve ölümlerin en sık yaşandığı sektörlerin başında gelmektedir. Bu açıdan sektörde İSG’nin sağlanması için diğer her türlü imkânın yanında teknolojik yeniliklerin de devreye sokulması önemlidir. Bu noktadan hareketle gerçekleştirilen bu çalışmada, çeşitli veri tabanları üzerinden “teknoloji” “inşaat sektörü” ve “iş sağlığı ve güvenliği” anahtar kelimeleri kullanılarak kapsamlı bir tarama yapılmış ve inşaat sektörüne yönelik İSG teknolojileri belirlenmiştir. Belirlenen bu teknolojiler, kullanım alanlarına göre gruplandırılarak literatürdeki uygulamaların yanı sıra, sahada kullanılan ticari uygulamalar da incelenmiştir. Çalışma, inşaat sektöründe İSG’nin sağlanmasına yönelik olarak geniş bir yelpazede birçok teknolojik uygulama bulunduğunu ortaya koymuştur. Çalışmanın bazen çok küçük maliyetlerle ölüm ile hayatta kalma arasındaki farkı yaratan İSG teknolojilerinin Türk inşaat sektörü paydaşlarına tanıtılmasına ve bu sayede bu teknolojilerin kullanımının yaygınlaştırılmasına katkı sağlayacağı değerlendirilmektedir.

Bu araştırmada 30 Ekim 2020 tarihinde Ege Denizi Sisam adasında meydana gelen (Mw:6.9) depremi sonrasında İzmir bölgesi sınırları içerisinde yer alan ve periyodik olarak ölçümleri yapılan 18 adet C1 ve C2 noktasının, bölgede meydana gelen deformasyondan kaynaklı olarak koordinatlarındaki değişim incelenmiştir. Deprem sonrası bölgedeki hız alanlarında 2020-2021 ve 2021-2022 yıllarındaki koordinat değişimlerinden bölgedeki deprem sonrası deformasyon haritaları çıkarılmıştır. Maksimum koordinat farkları depreme yakın olan SFRH, SIGA ve KBR5 noktalarındadır. Bu noktaların hareketlerinin D-KD yönlü olduğu görülmektedir. BSYL noktasının deprem merkezüssüne en uzak nokta olmasına rağmen yaklaşık 38 mm KD yönlü bir hareket görülmektedir.

Native valve aortic endocarditis is rarely seen in the paediatric population. Although, the first-line of treatment is medical, surgical intervention may be indicated in patients with unrepairable valvular and subvalvular disease. Recently, the aortic valve neocuspidization (AVNeo) procedure has gained popularity both in adult and children in whom other repair techniques are not feasible. In this case report, we present an urgent aortic valve replacement using the AVNeo technique in a critically ill infant with a small annulus, severe left ventricular outflow tract stenosis, and severe aortic regurgitation.

Purpose This paper aims to address the influence of lubrication methods on operational characteristics, power losses and temperature behavior of gears and bearings. It contributes to the improvement of resource and energy efficiency of geared transmissions. Design/methodology/approach Experimental investigations were performed at a gear and bearing power loss test rig. Thereby, dip lubrication, injection lubrication with injection volumes from 0.05 to 2.00 l/min and minimum quantity (MQ) lubrication with an injection volume as little as 28 ml/h were considered. Measurements were evaluated in terms of no-load and load-dependent power loss, bulk temperatures and mean gear coefficients of friction. Findings Results show strongly reduced no-load gear and bearing losses for lubrication methods with low lubricant quantities. Load-dependent losses are similar to conventional lubrication methods and tend to be lower at high speed. This is related to higher bulk temperatures, as the heat dissipation of lubrication methods with low oil quantities is limited. Limited thermal load limits were shown to be extended by LowLoss gears. Originality/value Systematic investigations were conducted to evaluate the influence of dip, injection and MQ lubrication on power loss and temperature behavior of gears and bearings. The results of this study support further research on needs-based lubrication methods for gearboxes.

Tarihi haritalar; geçmişin izlerini günümüze yansıtan eşsiz eserlerdir. Bu haritalar hem üretildikleri dönemin coğrafi özelliklerini barındırırlar hem de sanatsal bir yöne sahiptirler. Bu sanat, geçmişin ayrıntılarını günümüz dünyasına taşıma sanatıdır. Tarihi haritaların öneminin fark edilmesi ile birlikte bu haritalar üzerinde yapılan çalışmalar zaman içerisinde çoğalmış, teknolojinin gelişmesi ile birlikte tarihi haritaların analizleri ve değerlendirilmeleri daha kolay hale gelmiştir. Bu çalışmada; Harita Genel Müdürlüğü (HGM) tarafından üretilen ve ücretsiz bir uygulama olan HGM Kürenin dijital arşivlemede kullanılabilirliği araştırılmıştır. HGM Küre uygulamasında Türkiye sınırları içerisinde hava fotoğraflarından üretilen 1/250.000 ölçekli ortogörüntüler ve topoğrafik haritalar ile altlık oluşturulmaktadır. HGM Küre haritasında en yüksek arazi çözünürlüğü ~45 cm’dir. Çalışmada HGM Küre uygulamasında değerlendirilmek üzere Pervititch haritaları sayısallaştırıldıktan sonra koordinatlandırılmıştır. Haritaların doğrulukları, HGM Küre uygulamasına yüklenmeden önce Karesel Ortalama Hata (KOH) ölçütü ile incelenmiştir. Sonucunda elde edilen KOH değerleri 20 cm ile 1.5 m arasında değişmektedir. Çalışmanın sonucunda HGM Küre uygulamasında yer alan araçların analiz yapmaya imkân verdikleri görülmüştür. Ancak Google Earth veya diğer benzer uygulamalardaki gibi arşivlerde bulunan haritaların başka bir CBS yazılımına ihtiyaç duymadan, HGM Küre platformu üzerinde sunulamaması bir eksiklik olarak göze çarpmaktadır. HGM Küre uygulamasının arşivlerde bulunan haritaların koordinatlandırılarak platform üzerinde sunulmasına olanak sağlaması ülkemizdeki tarihi haritaların dijital arşivlemesinin sağlanması açısından iyi bir gelişme olacaktır.

Microbial fertilizer helps the plants grow healthy and stay strong due to including fertilizer and beneficial microorganisms. The purpose of the study was to determine the effects of microbial fertilizers applied in different growth stages on oil content, fatty acid composition and oil quality of peanut (Arachis hypogaea L.). The study was conducted in Osmaniye/Turkey in 2019 and 2020 according to RCBD arranged in split-plots design with 3 replications. The highest oil contents were observed in 150 cc da-1 (53.07%) and beginning bloom + full bloom (53.95%) treatments in studied years. For total unsaturated fatty acid compositions, the highest values were obtained in full bloom (79.49%) and 100 cc da-1 (79.99%) treatments. The highest O/L ratio were observed in full bloom and 100 cc da-1 treatments as 1.72 and 1.68, respectively according to mean of 2-year values. Similar results were seen in IV, and these treatments came forefront with the values 93.83 and 94.52, respectively. As a results of the study, it was concluded that (i) microbial fertilizers had the positive effects on oil content and quality parameters of peanut, (ii) the treatment 100 cc da-1 applied in full bloom may be the optimum selection.

Agriculture, which has historically been the main employment generating sector, is still very important in newly industrializing countries such as Turkey. Theoretically, it is thought that its share in GNP will decrease over time, but the depth of the decrease will depend on the economic impact of agriculture. One way to measure this effect is to adapt the Phillips curve for the agricultural sector. Therefore, the aim of this study is to analyse the validity of the Phillips curve in the Turkish agricultural sector. The study is conducted by the Augmented Dickey Fuller, Phillips Perron and Zivot-Anders Unit Root Tests as well as Nonlinear Autoregressive Distributed Lag and Autoregressive Distributed Lag tests via TURKSTAT 2014Q1-2020Q3 dataset. Reviewing these test, we find that the cointegration coefficient calculated by the NARDL model is negative, yet statistically significant. Accordingly, the short-term imbalances are eliminated in the long-run and the system converges to the long-run equilibrium values. Nonetheless, since the coefficient is greater than one, it is a sign of significant fluctuations in the convergence of the system to the long-term equilibrium. Additionally, the long-run negative cointegrated relationship of unemployment and inflation indicates that the Phillips Curve is valid in Turkish agricultural sector.

Türk ve Kırgız edebiyatı söz konusu olduğunda 20.yy’e kadar daha çok şiir akla gelmektedir. Bunun sebebi hem sözlü hem de yazılı edebiyatta eserlerin daha çok şiir formatında olmasıdır. Kırgız ve Türk Âşık şiir geleneğinde din, başat bir unsurdur. İslâm, Türk edebiyatının devirlere ayrılmasındaki en önemli faktördür. Bu sebeple âşık şiir geleneğinde din olgusunun iki ayrı dönemde ele alınması doğru olacaktır. Birincisi iki toplumun İslâmiyet öncesi âşıklık geleneğinde din olgusudur. Bu noktada iki toplumun şiir tarihine bakıldığında başlangıcından beri dinin, şiirin yani âşıklık geleneğinin oluşumunda etkili olduğu görülmektedir. İki halkın dini şiirleri mukayeseli olarak incelendiğinde benzer tarihlerde aynı dine inandıkları, bunları âşıklık (akın) geleneğiyle şiirlerine yansıttıkları, bir kısmını da bugünlere kadar saklamayı başardıkları görülmektedir. İkinci olarak İslâmiyet sonrası âşıklık geleneğinde dinin kuvvetli bir şekilde varlığı görülmektedir. İki toplumun İslamlaşma sürecinin farklı olduğunu, şiirlere de farklı yansıdığını görmekteyiz. Bu tebliğde özellikle Türk âşıklık geleneğinin oluşmasında İslâm’ın dolayısıyla tasavvuf düşüncesinin ve tekke pratiğinin üzerinde durulacaktır. Bu tarzın temsilcileri 19. yy sonuna kadar bir tekke ve tarikatla olan irtibatını devam ettirmiştir. Âşık kavramı, başından bugüne kadar Allah/Hakk âşığı anlamında kullanılmıştır. Bu konunun seçilme nedenlerinden biri de başlangıcından günümüze kadar bu geleneğin halkı çok etkilemiş olmasıdır. İki toplumun geleneğinde de bu şiirlerin içinde hurafe ve batıl inançların yer alması önemlidir. Kırgızlar bu ritüellere ırım-cırım der. Bugün Kırgızistan’da eski dinlerle İslam inancının senkronize olarak kullanıldığı, bunun da zenginlik olarak kabul edildiği görülmektedir. Oysa İslâm inancı bunu kabul etmemektedir.

Background MicroRNAs are small, endogenous, non-coding RNAs that regulate the expression of many genes. It has recently been shown that circulating microRNAs may be biomarkers of hypertrophy and fibrosis in patients with hypertrophic cardiomyopathy (HCM). Objective To determine whether circulating levels of microRNAs involved in HCM are associated with electrocardiographic and echocardiographic parameters. Methods This study enrolled 20 patients with familial HCM and 20 blood donors. Peripheral serum levels of miR-29a-3p, miR-199a-5p and miR-451a were assessed by quantitative real-time polymerase chain reaction and compared with levels in the control group. Whether circulating levels of miRNAs in HCM patients correlated with electrocardiographic and echocardiographic parameters was also assessed. Results Median circulating levels of miR-29a and miR-451a were significantly higher in HCM than the control group. Median miR-199a levels did not differ between groups. However, circulating levels of miR-199a negatively correlated with corrected QT duration (Bazett formula). Median miR-29a levels positively correlated with QRS duration. In addition, circulating levels of miR-29a correlated with maximal wall thickness, left ventricular mass index and left atrial volume index. Conclusions The data suggested that serum levels of miR-29a and miR-451a were significantly increased in HCM patients. As the circulating level of miR-29a correlated with QRS duration, left ventricular hypertrophy and left atrial dilatation, the serum miR-199a level negatively correlated with corrected QT duration. These miRNAs may be seen as potential biomarkers for further research in HCM pathophysiology.

Some insects cause high losses of the common bean during storage, namely, Acanthoscelides obtectus Say. Chemical insecticides are commonly used to control insects, but their overuse adversely affects the environment and consumers' health. There is, therefore, the need for an alternative control method. This study was aimed to evaluate the chemical characterization and insecticidal property of Moringa oleifera seed extract on the developmental stages of A. obtectus in stored beans. Three types of M. oleifera seed extracts, namely methanol, ethanol and acetone extracts, were used at doses of 12.5, 25 and 50 µl/ml each. HPLC-MS was used to characterize these extracts. The toxicity of extracts against the adults, the number of eggs and the viability rate of laid or emerged eggs of A. obtectus were evaluated. The results show that M. oleifera seed extract is rich in Hesperidin, Quinic acid, gallic acid, protocatechuic acid, 4-OH benzoic acid, cynaroside, isoquercitrin, cosmosiin, quercitrin, luteolin, naringenin, salicylic acid, Apigenin and Fumaric acid. The acetone extract, from day 2, showed a 100% mortality rate in all doses compared to about only 14% in the control treatment. The number of eggs laid in control (236.67) was higher than the null (0) in acetone treatment at 50 µl/ml. M. oleifera seed extracts contain chemical molecules. They significantly reduced the damage caused by A. obtectus on stored P. vulgaris grains. Therefore, they can be used as an alternative to chemicals for the protection of stored foodstuffs.

The use of Salvia species among the public and their importance in the scientific world increase due to theirnumerous pharmacological and biological activities on a daily basis. In this study, the phytochemical contents ofdifferent parts (root, branch, leaf, flower, whole) of different specimens of Salvia siirtica (SS) (in vivo and in vitro)extracts prepared with various solvents (petroleumether, chloroformand ethanol) were determined using differenttechniques (GC-MS and LC-MS/MS) and the results were compared. In addition, biological activities (antioxidant,cytotoxic, anticholinesterase antiurease, antityrosinase, antielastase and anticollagenase) of all sampleswere determined and compared. The antioxidant potential of the analysed samples was found to be high, andtheir enzyme activity potential was low. Besides, in vitro SS-TIS (Temporary Immersion System) sample showedhigh cytotoxic activity (viability% 2.12 § 0.06) against MCF-7 (breast cancer) cell line. The results of GC-MS andLC-MS/MS analyses indicated that ferruginol and sugiol could be isolated from the ethanol extract of S. siirticaroots, salvigenin and b-sitosterol from the chloroform extract of the aerial parts, and phenolic compounds fromthe ethanol extract of the aerial parts. In addition, the amount of rosmarinic acid, caffeic acid and 12-demethylmulticaulineof in vitro samples were found to be higher than those of in vivo samples. Furthermore, all samples,both in vivo and in vitro, contained high levels of rosmarinic acid and b-sitosterol. The whole chloroform extract(SSWC) could be the source extract for salvigenin (33952.13 mg/g) and b-sitosterol (16369.71 mg/g), and the rootethanol extract (SSRE) for ferruginol (17721.99 mg/g). As a result, it is understood that the nature of the plantmaterial, the choice of an appropriate solvent and the parts of the material used are quite effective in chemicalcontent. S. siirtica promise potential natural antioxidant agent in food and/or pharmaceutical industry due to itsphytochemical content (rosmarinic and caffeic acids, ferruginol, salvigenin) and antioxidant activity.

Introduction: The aim of this study was to investigate the change in frontal QRS-T angle in different clinical stages of scorpion stings. Materials-Method: In this retrospective study, laboratory data of patients and T angle, QRS duration (ms), QT duration (ms), and QTc duration (ms) of the patients who presented with scorpion sting were calculated and recorded in the data file. The results were analyzed. Findings: Eighty patients who applied to the emergency department with the complaint of scorpion sting were included in our study. Forty-four patients were evaluated as Stage I, 26 as Stage II, and 10 as Stage III. The patient groups did not differ in age (p = 0.605) and sex (p = 0.432). No significant difference was observed between the laboratory findings of the patients at the time of admission. ECG findings showed a considerable difference in frontal QRS-T angles between scorpion sting stages (p < 0.001). Pairwise comparison of the stages with post-hoc analysis revealed a non-significant difference between Stages I and II (p = 0.143), and a significant difference between Stages I and III (p < 0.001) and Stages II and III (p = 0.003). Correlation analysis results showed that the frontal QRS-T angle was negatively correlated with age (r = −0.281, p = 0.016) and positively correlated with the clinical stage (r = 0.384, p = 0.001). Multivariate linear regression analysis was performed to identify independent predictors of frontal QRS-T angle, and the stage of the scorpion sting was identified as an independent predictor (p = 0.001). Conclusion: The increase in frontal QRS-T angle in scorpion stings may be used as a parameter that can help both early detections of cardiac involvement and clinical staging

Ongoing research aims to investigate blood-based biomarkers and use them in acute ischaemic stroke (AIS) diagnosis and management of patients with AIS.The purpose of the present study was to investigate the meteorin-like protein (Metrnl) levels secreted by adipose tissue in patients with AIS.The study groups included healthy controls (n=30) and patients diagnosed with AIS via magnetic resonance imaging (MRI) in the emergency department (n=35) during the one-year period. The basic laboratory values and Metrnl, total antioxidant capacity (TAC), total oxidant status (TOS), and oxidative stress index (OSI) levels of the patients were compared. The Metrnl levels were measured using enzyme-linked immunosorbent assays.In the present study, the Metrnl (p=0.001) and TAC (p=0.009) levels decreased significantly, whereas the TOS (p0.001) and OSI (p0.001) levels increased significantly in the patients with AIS compared to the healthy controls. Furthermore, a cut-off value of ≤1.63% meteorin-like protein rendered the sensitivity and specificity rates of 91.43% and 71.43%, respectively, in the patients with AIS. In addition, there was a significant negative correlation between the decreased meteorin-like protein levels and the infarct diameter in patients with AIS.In patients with AIS, the meteorin-like protein levels decreased inversely with the infarct diameter, and at the same time, there was an increase in TOS and OSI levels and a decrease in TAC levels.

Plant density can have a major impact on peanut (Arachis hypogaea L.) yield. Information is limited in the Eastern Mediterranean Transition Region of Turkiye on growth, development, and yield of peanut cultivars based on plant density. To address this limitation, the cultivars Aysehanim, Rigel, Halisbey, Masal, and NC 7 were established in a single row planting pattern consisting of rows spaced 70 cm apart with an inter-row plant distance of 15 cm (95.000 plants ha-1) versus a twin row planting pattern consisting of rows spaced 20 cm apart on 90 cm centers with an intra-row distance of 15 cm (148.000 plants ha-1). The interaction of cultivar × plant density was significant for most variables. Irrespective of cultivar, establishing a plant population of 148.000 plants ha-1 in the twin row planting pattern resulted in greater pod yield than the single row planting pattern with a plant density of 95.000 plants ha-1. Pod yield was similar for Rigel, Masal, and NC 7 in the twin row planting pattern and exceeded that of Aysehanim and Halisbey. Conversely, yield of Rigel and Halisbey was similar in the single row pattern and exceeded yield of Aysehanim and NC 7.

Since calixarenes are more easily synthesized and functionalized than other supramolecules, they are compounds of interest in organic chemistry. In this study, the dihydrazide (3a and 3b) and diamino propyl (6a and 6b) derivatives of p-tert-butylcalix[4]arene and calix[4]arene were synthesized. Then the L-proline methyl ester substituted chlorocyclopropenium was reacted with the calix[4]arene derivatives (3a, 3b, 6a, and 6b) at room temperature in CH2Cl2 to obtain calix[4]arene superbase derivatives (4a, 4b, 7a, and 7b) in 75%, 60%, 70%, and 55% yield, respectively. The synthesized compounds' structure was elucidated using spectroscopic techniques (FTIR, H-1 NMR, and C-13 NMR). The cytotoxic properties of the calix[4]arene superbase derivatives were investigated against different human cancer cell, including A549, DLD-1, HEPG2, and PC-3 and human healthy epithelium cell line PNT1A. The cytotoxicity results showed that calix[4]arene superbase derivatives inhibited the proliferation of DLD-1, A549, HEPG2, and PC-3 cells in a dose-dependent manner. Compound 7a had the highest toxic effect on colorectal carcinoma (IC50: 4.7 mu M), and the IC50 values were 18.5 mu M and 74.4 mu M against human prostate and lung cancer cells, respectively. Furthermore, compound 4b was found more effective on hepatocellular carcinoma cells (IC50: 210.2 mu M). As a result, the synthesized calix[4]arene superbase derivatives can be developed to treat different human cancer cell. They can be considered as a preliminary result for molecular-level research.

This work proposes a new approach to characterize the mechanical properties of nanowires based on a combination of nanomechanical measurements and models. Silicon nanowires with a critical dimension of 90 nm and a length of 8 μm obtained through a monolithic process are characterized through in-situ three-point bending tests. A nonlinear nanomechanical model is developed to evaluate the mechanical behavior of nanowires. In this model, the intrinsic stress and surface parameters are examined based on Raman spectroscopy measurements and molecular dynamics simulations, respectively. This work demonstrates a new approach to measure the mechanical properties of Si nanowires by considering the surface effect and intrinsic stresses. The presented technique can be used to address the existing discrepancies between numerical estimations and experimental measurements on the modulus of elasticity of silicon nanowires.

Bezoars are concretions of undigested or partially digested foreign material in the gastrointestinal tract. They occur in patients with altered gastrointestinal motility or anatomy (previous gastricsurgery, diabetes mellitus, neurological disorders). They are rare, with an estimated %0.3 on upper endoscopy. The most common symptoms include abdominal pain, nausea, vomiting, early satiety, anorexia, and weight loss. We present a patient who diagnosed with 8-9 cm phytobezoar, and treated by endoscopic method. An 87 years old woman presented to our emergency room with upper abdominal pain, nausea, and postprandial emesis for 3 days. Emergency esophagogastroduodenoscopy revealed prepyloric antrum, gastric phytobezoar (8-9 cm) and ulcers (10-12 mm). We used an endoscopic snare to cut the bezoar into several pieces. After endoscopy, all bezoars disappeared. There was no recurrence during 1-year follow-up. In conclusion, endoscopic treatment may be a safe and viable option for the extraction of gastric bezoars presenting with gastric outlet obstruction. This is the rare case that such a large phytobezoar (8×9 cm) has been fragmented with an ordinary polypectomy snare.

Background The aim of this study was to examine the relationship between healing response after non-surgical periodontal treatment and baseline gingival tissue levels of M2 macrophage activation-related proteins CD163, interleukin (IL)-10, interferon (IFN)-gamma, and tumor necrosis factor-like weak inducer of apoptosis (TWEAK), and the CD163/TWEAK ratio. Methods Eighty-eight gingival tissue samples from 44 Stage III/IV, Grade C periodontitis patients (18 smokers) and 41 tissue samples from 41 periodontally healthy participants (18 smokers) were evaluated. Clinical parameters were recorded in periodontally healthy individuals at baseline and in periodontitis patients at pre-treatment and 2, 6, and 12 weeks following therapy. IL-10, IFN-gamma, CD163, and TWEAK levels were analyzed with Luminex technique. Results Tissue levels (median, 1(st)-3(rd) quartile) of IL-10 (pg/ng protein), CD163 (pg/mu g protein) and TWEAK (pg/mu g protein) were as follows: IL-10 periodontitis: 2.08, 0.86-5.32 and periodontally healthy: 5.22, 3.20-10.25; CD163 periodontitis: 8.85, 4.92-14.06 and periodontally healthy: 18.36, 12.51-34.02; TWEAK periodontitis: 0.08, 0.05-0.11 and periodontally healthy: 0.16, 0.12-0.21. IL-10, CD163, and TWEAK levels were higher (P < 0.001) in periodontally healthy tissues than in periodontitis tissues. Pocket closure at 12 weeks was associated with elevated baseline gingival CD163 levels (P = 0.047) and CD163/TWEAK ratio (P = 0.001). Elevated baseline gingival CD163/TWEAK ratio was associated with pocket reduction at 6 (P = 0.022) and 12 weeks (P = 0.002). Conclusion Associations of pocket closure with pre-treatment gingival tissue CD163 levels and CD163/TWEAK ratio indicate that baseline M2 macrophage activation profile may play a role in periodontal wound healing.

Synthesis of 1,8-naphthalimide derivatives and biochemical studies using them as anti-cancer and cellular imaging agents have attracted significant attention in recent years. This study aimed to synthesize two new fluorescent lower rim-functionalized 4-sulfo-1,8-naphthalimide derivatives of calix[4]arenes [4 and 7] and examination of their cytotoxic properties for cancerous cells. For this purpose, p-tert-butylcalix[4]arene bearing dihydrazide [3] or diaminopropyl [6] units on its lower rim were reacted with 4-sulfo-1,8-naphthalic anhydrate. The structure of these synthesized compounds has been characterized using 1H-NMR, 13C-NMR, and FT-IR techniques. To investigate the anti-cancer properties, compounds 4, 7, and N,N-dimethylaminoethyl-1,8-naphthalimide [8] were tested on the human colorectal cancer cell line (DLD-1) as well as healthy colon epithelial cell line (CCD-18Co). The IC50 values of 4 and 7 were determined as 12.95 µM and 16.13 µM, respectively, on DLD-1 cells. Furthermore, following the treatment of CCD-18Co cells with 4 and 7, the IC50 values were determined as 508 µM and 269 µM, respectively. However, it was observed that compound 8 had no cytotoxic effect on both DLD-1 cells and CCD-18Co cells. Furthermore, the fluorescence imaging of human colorectal cancer cells treated with the synthesized compounds [4, 7, and 8] was performed on living cells.
