EFFECT OF NITROGEN AND FOLIAR APPLICATION OF PHENOLIC COMPOUNDS ON FLAG LEAF PIGMENTS AND GRAIN YIELD OF SPRING WHEAT (Triticum aestivum L.) GENOTYPES

Application of phenolic compounds such as proline, glycinebetaine, silicon, cytokinins, methanol etc. are getting important consideration in modern agricultural research for managing plants to get maximum yield under different environmental conditions. However there is a lack of knowledge about the effects of these phenolic compounds on grain yield, yield components and physiological properties such as leaf photosynthetic pigments. In the context the the present study was conducted during 2015-2016 growing season at the experimental field in the faculty of agriculture, University of Cukurova, Adana, Turkey to evaluated the effects of some phenolic compounds such as proline, glycinebetaine, silicon, cytokinins, methanol etc on chlorophyll (Chl) as well as total carotenoid contents of four bread wheat genotypes (‘Adana-99’, ‘FSD-2008’, ‘Basribey-98’ and ‘Seher-06’) under two nitrogen levels viz., low nitrogen level, LN: 60 kg N ha-1 and high nitrogen level, HN: 180 kg N ha-1 under well-watered condition. The results of the LN showed that the grain yield was only significantly correlated with Chla/b (r=-0.751**) of wheat genotypes. While, under HN, Chla, Chlb, carotenoid and Chla/b were strongly correlated with grain yield (r=0.422*, r=0.635**, r=0.444* and r=-0.590**) respectively. Among the phenolic compounds, proline highly sitimulated the relationships between grain yield and Chlb, carotenoids and Chla/b (r=0.795*, r=0.795* and r=0.811*), respectively. Similary, methanol effects were strongly correlated with grain yield and Chlb and Chla/b (r=0.844** and r=-0.772*), respectively. Therefore it is concluded that foliar application of methanol and proline were significantly increased the flag leaf Chlb concentration which ultimately lead to increase the grain yield of wheat genotypes

Comparison of long-term kidney functions after radical nephrectomy and simple nephrectomy

Objective To determine if there is a difference in proceeding to CKD between patients who had undergone radical nephrectomy (RN) and simple nephrectomy (SN) for different indications by comparing the short- and long-term renal function. Materials and Methods We retrospectively analyzed the records of all patients who underwent nephrectomy (either for malign or benign indications) in our clinic between January 2007 and September 2017. The patients were divided into 2 groups according the type of surgery: 1) Radical nephrectomy Group, 2) Simple Nephrectomy Group. Renal function was evaluated with Glomerular Filtration Rate (GFR) calculated using the MDRD formula. Results A total of 276 patients were included in the study. There were 202 patients in RN Group and 74 patients in SN Group. The mean age of the patients in RN Group and SN Group were age 59,2 ± 11,5 and 49,9 ± 15,1 years, respectively (p = 0.001). GFR levels of patients in RN Group versus SN Group were as follows: Preoperative period: 84.9 vs. 81 mL/min/1.73 m2; postoperative 1st day: 60.5 vs. 84.4 mL/min/1.73 m2, postoperative 1st month 58.9 vs. 76 mL/min/1.73 m2, postoperative 1st year: 59.5 vs. 74.1 mL/min/1.73 m2; at last control 60.3 and 76.1 mL/min/1.73 m2. While preoperative GFR was found to be similar in two groups (p = 0.26), postoperative GFR values were found to be significantly lower in Group RN (p < 0.001). In comparison of the decrease in GFR in two groups at last follow-up, significantly higher decrease was observed in RN Group, 29% vs. 6%, (p < 0.05). Conclusion The decrease in GFR exists more common and intensive after RN compared to SN. In long-term, compensation mechanisms that develop after sudden nephron loss like radical nephrectomy deteriorates kidney function more than gradual nephron loss as in benign etiologies which indicates simple nephrectomy

The aim of this research is to determine the important variables that predict the PISA 2018 reading field achievement score of countries with different achievement levels, using 34 independent variables obtained from the student questionnaire given to the students who participated in PISA in 2018. For this purpose, 79 countries that entered PISA were ranked according to their success percentages and according to this ranking, these countries were divided into lower, middle and upper group countries.Then, three countries were selected from each of the lower group, middle group and upper group countries and nine different samples were obtained, all of these nine countries were determined as the study sample. The sample of Turkey, which is one of the three countries selected for the middle group, was also included in the study independently. Then, data mining analyzes were carried out on Turkey, the sample of lower, middle, upper group countries and the study sample using logistic regression, Classification and Regression Tree and Random Forest methods. It has been observed that the number of important variables that predict reading comprehension success can be reduced from 34 to a number between two and eight. Like this; Data mining classification prediction models, which can predict the PISA success level, were obtained by using a small number of variables. It was determined that the models obtained had high predictive performance in the two-category (unsuccessful-successful) prediction of success and acceptable in the three-category (low, medium-high) prediction. According to the results obtained, among the 34 independent variables, first of all, PISA test's perception of difficulty, reading pleasure, father's education level, perception of reading difficulty, socio-economic level index, meaning of life, teacher's direction of education and weekly test language learning time were used in different estimation models of 27 variables were found to be important variables.Bu araştırmanın amacı, 2018 yılında PISA’ya katılan öğrencilere sınavla birlikte verilen öğrenci anketinden elde edilen 34 bağımsız değişkeni kullanarak, farklı başarı düzeyine sahip ülkelerin PISA 2018 okuma alanı başarı puanını yordayan önemli değişkenleri belirlemektir.

İyi düzenlenmiş plazmonik arayüzeylerin, nanoküre litografi yöntemi ile üretimi.

In this thesis, we propose to design plasmonic metal nanostructures by utilizing lithography with nanospheres of various diameters. When deposited at a high surface coverage, nanospheres form closed-pack trigonal lattices on surfaces, leaving concave triangular gaps in-between. After evaporation of thin metal films and lifting-off the nanospheres, metal islands which support plasmonic resonances and of the gap shape are fabricated in a trigonal periodicity on the substrate material. Depending on nanosphere diameter, the size of the triangular shaped nanostructures can be rearranged. In addition to classical nanosphere lithography (NSL) method, the physical influences that affect the fabrication method were also be considered in order to move beyond one step further. In other words, using annealing and physical etching mechanisms; size, shape of nanostructures and total surface coverage parameters were taken under control without deforming the system. Using these, our aim is to produce metal nanoparticle in desired shape and periodicity for plasmonic applications. Moreover, another goal is to prove that nanosphere lithography is a powerful tool especially for surface modification. In order to show that, how close-pack structure can be used is discussed by giving examples of different lithographic modifications. In this thesis work, we focus on experimental details of NSL and its extensions. After defining stages of production, we also show that NSL can be used to fabricate periodic metal structures with identical geometry and size, plasmonic interfaces with adjustable surface coverage, microlens arrays, and capability for generating 3D photonic crystals and adaptability with different lithography methods. In order to show them, we have used Scanning Electron Microscope (SEM), Raman Spectroscopy, total reflection techniques to characterize the nanostructures. Thanks to Comsol simulations and Gwyddion image analysis, experimental results are analyzed.M.S. - Master of Scienc

Inflammatory bowel disease is an independent risk factor for male erectile dysfunction

Background and objective: Inflammatory bowel diseases (IBD) are chronic diseases involving the gastrointestinal system, including ulcerative colitis (UC) and Crohn’s disease (CD). Studies have shown a relationship between inflammatory bowel diseases and sexual dysfunction in men but it has been reported that this is due to surgery or the patient’s psychological state. In our study, we aimed to assess the impact of IBD on the sexual functioning of male patients who has no previous pelvic surgery by evaluating the depression status of the patients. Materials and methods: The 334 patients who were followed up in our gastroenterology outpatient clinic between January 2021 and March 2021 were included in the study and they were divided into 2 groups as with (n = 146) and without IBD (n = 188). None of the patients had a history of pelvic surgery or pelvic radiotherapy due to IBD or any other disease. The two groups were compared in terms of demographic data, comorbidities, sexual function, depression status and blood tests. International Index of Erectile Function (IIEF) was used in the evaluation of sexual functions, and the Beck Depression Inventory (BDI) was used in the evaluation of depression. Risk factors for erectile dysfunction (ED) were determined. Results: The mean Beck depression test scores of the two groups were found to be similar (p = 0.361). ED was detected in 52.7% of patients with IBD and 32.4% of patients without IBD (p < 0.0001). In multivariate regression analysis, age (p = 0.008), smoking (p < 0.001), presence of diabetes mellitus (p = 0.02) and presence of IBD (p < 0.001) were determined as independent risk factors for ED. Conclusion: Inflammatory bowel diseases can cause ED regardless of the pelvic surgery performed and the psychological status that occur in these patients

Case Report Pregnancy Outcome after Varenicline Exposure in the First Trimester

To the best of our knowledge this is the first case report describing exposure to varenicline, an 4 2 nicotinic acetylcholine partial receptor agonist used for smoking cessation therapy in pregnancy. A 29-year-old multiparous woman with an unplanned pregnancy has used varenicline 2 mg/day unintentionally yet regularly 4 weeks from her last menstrual period. Fetal ultrasound performed at each trimester, detailed anomaly scan, and fetal echocardiography which were performed at the 22nd gestational week showed normal fetal growth with no malformations. The patient delivered a healthy baby at the 38th week of gestation with normal Apgar score and physical examination findings. Age-appropriate physical and neurological development of the child has been observed for 6 months. Although it is not possible to draw definitive conclusions, this case report may contribute to the current available limited data regarding the safety of varenicline use in pregnancy
