Y. Ersoy Yildirim,Belgin Cakmak,Tamer Kose
Journal of Applied Sciences , 2004,
Abstract: In this study, hourly and daily reference plant water consumptions were calculated by Penman Monteith equations, using meteorological data of temperature, relative humidity, solar radiation and wind speed obtained in 12 min periods from an automatic metrological station in Koruklu Research Station which represents Harran plain and is located within GAP region borders. Daily reference plant water consumption values (ET0_H) obtained by adding the calculated hourly plant water consumption values were compared with directly calculated daily reference plant water consumption values (ET0_D) for 2001-2002 period between the dates May1 and September 30 and statistical analysis were carried out. As a result of the study, it was found that ET0 values calculated by different approaches exhibited a linear relation and ET0_D values exhibited non-coincidently higher values than ET0_H for all periods investigated

Lung India , 2008,
Abstract: Objective: Non-small cell lung carcinoma is an aggressive phenomenon and the epigenetical alterations of some tumor supressor genes have been reported for the different tumor types. Case Presentation: It is presented a case report concerning a 43 years old male with NSCLC on the lower segment of the right lung. The patient underwent a diag-nostic excisional thin-needle biopsy and after the histological confirmation. We examined the promoter methylation status of some distinct tumor supressor genes in tumoral and blood tissues of the case after sodium bisulfite conversion and DNA amplification with methylation specific multiplex PCR technique. Both tissues were also searched for G to A transitions in codons 12 and 13 of the K-ras proto-oncogene. Results: Tumor specimen showed fully methyl pattern profiles for the SFRP2, p16, DAPK1 and partially hyper-methylated profile for the p53 and MGMT genes in this case with non-small lung carci-noma. Blood speicemen showed normal hypomethylated profiles for all studied TS genes. The K-ras proto-oncogene was in normal structure both in blood and tumoral spiecemens that examined. Conclusion: Results indicate that genes exhibit tumor suppressor activi-ties in blood, but exhibit epigenetic inactivation in carcinoma cell. These findings strongly support the hypothesis that epigenetic mechanisms may play an important role in the non-small cell lung carcinogenesis in human.

Alper Parlakgumus, Sedat Yildirim, Naime Tokmak, Tamer Colakoglu, Kenan Caliskan, Ali Ezer, Gokhan Moray
Journal of Medical Case Reports , 2009, DOI: 10.1186/1752-1947-3-6491
Abstract: Here we report the case of an 18-year-old Turkish woman with schizophrenia who was admitted to the emergency department with signs of an acute abdomen as a result of ingestion of multiple needles. This is the third case in the literature for which mini C-arm fluoroscopy has been used to localize metallic sewing needles.When intentional ingestion occurs, surgery is rarely required. It is hard to localize ingested sewing needles and mini C-arm fluoroscopy is a good alternative when metal detectors are not available for localization of metal sewing needles. We recommend this approach because it helps to avoid unnecessary exploration, shortens the duration of surgery and provides outstanding results.Foreign body ingestion has been a fundamental subject in the area of pediatrics, emergency surgery and gastroenterology. Intentional ingestions of foreign bodies occur as a result of many factors such as self-demanding impulsivity, attention-seeking behavior in people with personality disorders, command hallucinations in the case of schizophrenia and in prisoners for the purpose of being transferred to a hospital. In the literature, mini C-arm fluoroscopy has rarely been rarely to detect metallic needles. Here we report an 18-year-old woman with schizophrenia who ingested multiple needles. This is the third case in the literature for which mini C-arm fluoroscopy has been used to localize metallic sewing needles.An 18-year-old Turkish woman with paranoid schizophrenia was admitted to the emergency department with a history of swallowing multiple sewing needles 20 days previously. She had progressive abdominal pain, nausea and vomiting. On physical examination, she was tachycardic, had abdominal tenderness, rigidity and a palpable prickling body under the skin on the left side of the umbilicus (Figure 1). Routine laboratory examinations revealed leucopenia and abdominal X-ray (Figure 2) and computed tomography (CT) showed three needles (Figure 3).Abdominal exploration was perf

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2010.1676.1680
Abstract: The experiment was conducted on heavy grazed rangelands in Erzurum. In this study, three forage species, crested wheatgrass (Agropyroncristatum), alfalfa (Medicago sativa) and smooth brome (Bromusinermis) were selected and mixed to establish for rangeland improving. Four treatments, artificial pasture, over seeding, fertilization and control were applied; main subjects were grazing free and enclosure to grazing for animal. About 10 kg N da-1 + 7 Kg P2O5 da-1 was applied as a fertilizer on over seeding and artificial seeding plots only in planted year, 6 kg N da-1 + 4 kg P2O5 da-1 on fertilization plots in each year. According to average of five study years, dry matter yield was 264.4 kg da-1 in fertilization plots; 183.2 kg da-1 was in artificial pasture plots in enclosed site. In grazed site, average dry matter yield was 114.7 kg da-1 in fertilized plots, 68.0 kg da-1 in artificial pasture plots and there was not significant difference between control and over seeding plots. There were significant differences among treatments for vegetation cover in enclosed and grazed sites. In all study years, vegetation cover was higher in fertilizer treatment plots than the other treatment plots but especially in 2008 and 2009 years, vegetation cover showed notable increase in fertilizer treatment plots compared to the other treatments.
The effect of vitamin C and cobalt supplementation on antioxidant status in healthy and diabetic rats

African Journal of Biotechnology , 2009,
Abstract: In the present study, liver, lung, heart and kidney superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT) activities, lipid peroxidation, nitrite and vitamin C levels were investigated in diabetic rats. Diabetes induced in rats by streptozotocin (STZ) and the treated rats were received 1 g/l vitamin C with 0.5 mM CoCl2 in drinking water for eigth weeks. In all tissues, superoxide dismutase, glutathione peroxidase, catalase activities, lipid peroxidation and nitrite levels were significantly increased in diabetic rats at the end of 8th week (p < 0.05) whereas vitamin C level was decreased compared to those of controls. Cobalt with vitamin C treatment of diabetic rats resulted in partial restoration of SOD and CAT activities, thiobarbituric acid reactant substances (TBARS), vitamin C and nitrite levels at all times studied, whereas treatment did not significantly change GSH-Px activity compared to diabetics. These results suggest that cobalt with vitamin C, effectively but could not completely restore the altered endogenous defense systems in diabetic rat liver, lung, heart and kidney tissues.

Abstract:

QPA (Quantitative Phase Analysis) of carbonate rocks bearing calcite and dolomite using X-ray diffractometry (XRD) can be performed using the combined Rietveld Structure Refinement (RSR) and semiquantitative Reference Intensity Ratio (RIR) methods, providing an estimation of crystalline phase in a mixture. Different ratios of five samples were prepared by mixing these crystal minerals with high sensitively. The scan speeds, adequate to determine mineral phases in rock samples, were used as 6 degrees per minute with 0.08 steps. The XRD analysis with commercial TOPAS 3.0 program, defined by a new generation of profile and structure analysis software, based on RSR provides Bragg reflection profiles and the dimension of the unit cell of a phase. The weight fractions of each phase were found by Le Bail and Pawley methods in RSR using a pseudo-Voigt peak shape model. The samples were also characterized by using X-ray fluorescence (XRF) and atomic absorption spectrometer (AAS). These analyses were conducted to compare these results with those obtained from the RSR. In addition to these, RSR of phases is very important to improve the goodness of fit (GOF). Therefore, the discussions of refinement of the carbonate mixing were made and a refinement procedure was given for these mixing in detail. Taking advantage of the RSR with the addition of an internal standard, the phase fraction of all the crystalline phases as well as the amorphous component, has been accurately determined. RSR technique offers a valid support for the characterization of marble in the light of industrial products.

Journal of Financial Risk Management (JFRM) , 2015, DOI: 10.4236/jfrm.2015.43013
Abstract: This study aims to measure the foreign exchange risks that the insurance companies are exposed to. In this context, this study analyzes 7 insurance companies listed in Borsa Istanbul (Istanbul Stock Exchange). The foreign exchange risks that the insurance companies are exposed to were measured using VaR models, Historical Simulation and Monte Carlo Simulation methods. Data obtained from the analysis show the losses that the insurance companies suffer due to exchange risk. The losses calculated using the Monte Carlo Simulation were found to be greater than the losses calculated using Historical Simulation.
