The Tumor Necrosis Factor-A -308 G/A Polymorphism and the Tumor Necrosis Factor-Related Apoptosis-Inducing Ligand Polymorphisms, in Asthmatic Patients and Healthy Subjects
Erdal, Mehmet Emin | Ay, Özlem İzci
Asthma is a chronic inflammatory disorder of the airways in which many cells and cellular elements play a role. Like other atopic diseases, asthma is a complex disorder caused by interactions between multiple genes of small to modest effect and equally important environmental factors. The aim of this study was to determine the TNF-α -308 G/A polymorphism and the TRAIL polymorphisms, and their influence on asthma in asthmatic patients and healthy subjects. The study population consists of 51 asthmatic patients (47 female and 4 male) and 72 healthy subjects (62 female and 10 male). The mean age of the asthmatic patients and healthy controls were 45.33±14.05, and 41.88±17.41 years, respectively. The asthmatic patients and healthy controls were similar with respect to their ages and sex charac...
Significance of catechol-O-methyltransferase gene polymorphism in myofacial pain syndrome
Erdal, Mehmet Emin
The objective was to investigate possible association of the catechol o-methyl transferase (COMT) gene polymorphisms with myofacial pain syndrome (MFPS). The polymorphism of the COMT gene was compared between 49 patients with MFPS and 113 control subjects. Relationship between COMT polymorphism and psychiatric status of the patients was also assessed using SCL-90-R, BDS, and STAI-I and II tests. A PCR-based restriction fragment length polymorphismassay was used to detect G ! A transition at position 1947 in COMT. There was no relationship between MFPS and COMT polymorphism (p > 0:05). The patients who had MFPS without any temporomandibular joint problem had signi cantly higher expression of LL genotype when compared to those with joint problems (p < 0:05). There was no relationship betwee...

Removal of imipramine using advanced oxidation processes: Degradation products and toxicity evolution
Doğan Çalhan, Selda | Görmez, Özkan | Gözmen, Belgin | Şüküroğlu, Ayça
Pharmaceuticals are frequently detected in natural and wastewater bodies, and are very important in environmental toxicology because of their stable nature. Advanced oxidation methods used to remove contaminants are of great benefit, especially removing pharmaceuticals unsuitable for biodegradation. In this study, imipramine was degraded by anodic oxidation and subcritical water oxidation, which are advanced oxidation methods. The determination of degradation products was performed by Q-TOF LC/MS analysis. The genotoxicity and cytotoxicity of the degradation samples were determined by the in vivo Allium Cepa method. Among the anodic oxidation samples, the lowest cytotoxicity was obtained after using 400 mA current, and 420 min of degradation time. No cytotoxic effect was observed in any su...
Role of 2.4 GHz radiofrequency radiation emitted from Wi-Fi on some miRNA and faty acids composition in brain
Erdal, Nurten | Erdal, Mehmet Emin
The purpose of this study is to investigate the effects of 2.4 GHz Wi-Fi exposure, which is continuously used in the internet connection by mobile phones, computers and other wireless equipment, on microRNA and membrane and depot fatty acid composition of brain cells. Sixteen Wistar Albino rats were divided equally into two groups such as sham and exposure. The rats in the experimental group (n = 8) were exposed to 2.4 GHz RFR emitted from a Wi-Fi generator for 24 h/ day for one year. The animals in the control group (n = 8) were kept under the same conditions as the experimental group, but the Wi-Fi generator was turned off. At the end of the study, rats were sacrificed and brains were removed to analyze miRNA expression and membrane and depot fatty acids of brain cells. We analyzed the s...
Effects of electromagnetic radiation on neurogenesis and gene expression in amniocytes
Erdal, Nurten | Ay, Özlem İzci | Yıldırım, Didem Derici | Durukan, Hüseyin | Erdal, Mehmet Emin
The aim of the study was to investigate the genetic effects of commonly used radiofrequency on the amniocytes of pregnant women by examining the changes in the expression of genes related to signal transduction and neurogenesis induced by electromagnetic fields of radiofrequencies of 1800 and 2100 MHz by real-time PCR. Upon exposure of the amniocytes to electromagnetic radiation of 2100 MHz at high field strength, the expression levels of genes with important functions in the Wnt signaling pathways as well as neurogenesis-related genes were increased. The findings suggest that radiofrequency at high field strengths can have genotoxic effects during pregnancy.
Not only Relational but also Structural: Revisiting there solution of the 1998 October crisis through elements of structural power
Sarı, Buğra
The 1998 October Crisis between Turkey and Syria has long beenstudied in various aspects. However, these studies are limited to anunderstanding that depicts the crisis as a relational power relation-ship in which Turkey forced Syria to cease its support for the PKK,which Syria would not have done otherwise. While not rejecting therelational explanation, this paper attempts to complement it witha structural approach, drawing on the post-positivist structuralpower conceptualization, by investigating how Syria’s structurallyshaped subjective interests in the post-Cold War international struc-ture and norms regarding international terrorism disempowered it resisting Turkey’s demands.

Degradations of model compounds representing some phenolics in olive mill wastewater via electro‐Fenton and photoelectro‐Fenton treatments
Gözmen, Belgin
The electrochemical oxidation of vanillic acid, o‐coumaric acid and protocatechuic acid, three representative toxic phenolics in olive mill wastewater, was studied using carbon felt cathode in the electro‐Fenton system. Results obtained, in the presence or absence of UV support, were compared throughout the degradation processes up to mineralization. It was demonstrated that all three phenolic compounds reacted completely with hydroxyl radicals and degraded efficiently. It was shown in the photoelectro‐Fenton process that the degradation and mineralization efficiency of the phenolic compounds were enhanced by the effect of UV light, especially at the later stages of the degradation processes.
Acid Red 1 and Acid Red 114 decolorization in H2O2-modified subcritical water: process optimization and application on a textile wastewater
Gözmen, Belgin
Solutions of Acid Red 1 and Acid Red 114 were treated in H2 O2 -modified subcritical water in the temperature range of 100°C–200°C for up to 60 min. Response surface methodology based on the Box-Behnken design was used to optimize the process. For Acid Red 1, optimum decolorization of 97% can be achieved at 192°C, 181 mM H2 O2 , 51.3 min treatment time, and 121 mg/L dye concentration. For Acid Red 114, the optimum conditions were 195°C, 157 mM H2 O2 , 38 min treatment time and 110 mg/L dye concentration, where 91% decolorization could be obtained from the proposed model. It was determined that temperature is the most important factor, followed by the oxidant concentration. Degradation was less efficient for AR114 due to the double azo bonds, compared to the single azo bond of A...
A study on water quality and trophic state of Akgöl Lagoon (Mersin, Turkey).
Alp, Mehmet Tahir | Fakıoğlu, Yunus Emre | Özbay, Özgür
This study aimed to determine the physicochemical characteristics of the water quality and trophic state of Akgol Lagoon located in the eastern Mediterranean. Cluster analysis clearly revealed the € spatial heterogeneity classifying sampling stations as saline and freshwater/brackish water sites. A multivariate analysis of variance followed by principal component analysis supported that salinity was major factor affecting physicochemical water quality variations in the lagoon. As salinity was mainly governed by freshwater inflows depending on agricultural irrigation, it can be proposed that water quality was significantly influenced from freshwater use by human activities. The parameters used as predictors (total nitrogen, total phosphorus, chlorophyll a and Secchi disk transparency) yield...
