The objective of the present work is to examine the effects of different doses (0, 10, 20 and 40 g kg(-1) fish diet mass) of kefir on growth performance and oxidant-antioxidant status in the blood and liver tissues of Coruh trout, Salmo coruhensis, in different periods (2 and 3 months). In this study, survival was more than 88.3%, and irrespective of dietary kefir levels at the end of the study. There were no significant differences in SGR (Specific growth rate), FCR (Feed conservation rate), CF (Condition factor) among fish fed diets with 0, 10, 20 and 40 g kg(-1) kefir, however, these growth values were significantly different in terms of durations between 2-month and 3-month treatment (P<0.05). Our results indicated that TAS (Total Antioxidant Status) and TOS (Total Oxidant Status) in blood tissues reduced with kefir treatment at the end of third month (P<0.05). Malondialdehyde (MDA) levels in liver decreased in all groups compared with control group and a considerable extent decrease was observed in 40 g dose of kefir treatment at the end of third month. The data obtained from this experiment indicated that the same dose of kefir was more effective at the end of 3-month treatment than 2-month treatment (P<0.001). Although there was no statistical difference among groups, an increase in the glutathione peroxidase (GSH-Px) enzyme activity was observed in all groups compared to control groups. While catalase (CAT) activity decreased in all groups compared to control group at the end of second month (P<0.01), the decrease was insignificant level at the end of third month. In glutathione (GSH) levels, statistical differences were no observed in all groups compared to the control group with 2-month treatment while there were significant increases with 3-month treatment (P<0.001). It was concluded that kefir could play an antioxidant role and its effectiveness depended on dosage and time of application in Coruh trout, S. coruhensis.

Ozbey, Ulku; Seyran, Ayse; Erisir, Mine; Benzer, Fulya; Savucu, Yuksel
Down syndrome is a chromosome abnormality with specific clinical symptoms and mental retardation caused by trisomy of chromosome 21. There is evidence that oxygen free radicals play an important role in the pathophysiology of many neuropsychiatric disorders. Although, it has not been investigated yet, several recent studies proposed that nitric oxide related to oxidative stress and arginase may have a pathophysiological role in mental retardation. The purpose of this study was to determine plasma nitric oxide levels and erythrocyte arginase activities in patients with Down syndrome and in healthy children. Plasma nitric oxide levels and erythrocyte arginase activity were measured in 20 patients with Down syndrome (median age: 15.6 +/- 7.5) and 20 age-matched healthy subjects (median age: 16.2 +/- 7.4). Significant differences were found between erythrocyte arginase activity of the patients with Down syndrome (35.2 +/- 2.7 U/g hemoglobin (Hb)) and those of healthy children (43.5 +/- 2.9 U/g Hb), (P < 0.05). But we have not found any statistical difference between persons with Down syndrome and control group for nitric oxide (P > 0.05). It was concluded that the level of erythrocyte arginase activity could be considered as a useful marker for assessing the level of mental retardation in children with Down syndrome.

This study has been carried out to investigate the presence of Yersinia ruckeri, the causative agent of Enteric Red Mouth (ERM) disease, in rainbow trout fish breeding farms located in Elazig and Malatya provinces in Eastern Turkey. For this purpose, bacteriological culture and a specific polymerase chain reaction (PCR) have been compare with examine blood and intestine samples collected from adult and young rainbow trout fish as well as water samples collected from all the farms. Y. ruckeri was isolated and identified from eight of the 17 fish farms giving a proportion of 52.9% at fish farm. The disease was noted in five of the rainbow trout farms located in Elazig and three of the 11 rainbow trout farms located in Malatya. The agent was detected in five of the six young fish breeding farms. The isolation percentages of the causative agent at fish level were calculated as 25.7% (131/510) in adult and 31.7% (19/60) in young fish, giving an overall proportion of 26.3% (150/570). All the isolates have been successfully identified as Y ruckeri by species-specific PCR. No isolation could be made from water samples. It is therefore concluded that Y. ruckeri infection poses a significant threat to the fish farms in the study area and necessary precautions should urgently be taken in order to minimize economical losses due to ERM disease. A specific PCR can be utilized successfully in aquaculture for rapid identification of bacterial agents which will help to prevent spread of infectious diseases and will therefore contribute to the productivity of fishery sector.

Sagliyan, A.; Benzer, E.; Kandemir, F. M.; Gunay, C.; Han, M. C.; Ozkaraca, M.
This study examined the effects of orally given grape seed extract (GSE) on healing of surgically induced full thickness skin wounds in terms of clinical, histopathological and biochemical aspects. A total of 48 healthy. adult male New Zealand rabbits were randomly divided in 2 equal experimental and control groups: one week prior the surgery, 260 mg/kg grape seed extract was orally given for 20 days to the assay animals. A circular full thickness skin wound (2.5 cm in diameter) was made in the back midline of all rabbits under anaesthesia then, macroscopic and histopathological aspects as well as the tissue oxidant/antioxidant balance were determined on 6 rabbits from each group slaughtered at the 5th, 10th, 15th and 20th days post-surgery. In treated rabbits, it was clinically observed that the wound contraction was significantly amplified and the histological processes of re-epithelisation, granulation tissue development, collagen accumulation and angiogenesis were markedly hastened whereas the inflammatory reaction and the ulcer disappeared more rapidly than in the not-treated controls. Furthermore, the maximal skin MDA formation observed on the 10th day was significantly depressed and the antioxidant catalase (CAT) and glutathione peroxidase (GSH-Px) activities remained significantly elevated until the 15th day compared to the controls. These results demonstrate the beneficial effects of treatment with GSE on skin wound healing in rabbits.

Bulut, Hasan; Baskonus, H. Mehmet; Tuluce, Seyma; Sivasundaram, S
In this paper, we studied to obtain numerical solutions of partial differential equations with variable coefficient by Sumudu Transform Method (STM). We applied to three examples this method. Then, we ploted 2D and 3D graphics of these equations by means of programming language Mathematica. In order to solve these differential equations which is ordinary and partial, the integral transforms such as the Laplace, Hankel and Fourier were unusually used and therefore there are several works on literature and applications of them. But it has few been given by using STM. And thus, in recent years STM has been an important places in applied sciences such as especially engineering, physics, physical sciences. Moreover, it is important for solving ordinary and partial differential equations which is linear and nonlinear.

Gul, Muhammet; Guneri, Ali Fuat
This paper presents a case study of a discrete-event simulation (DES) model of an emergency department (ED) unit in a regional university hospital in Turkey. In this paper emergency department operations of the hospital were modeled, analyzed and improved. The goal of the study is to reduce patient average length of stay (LOS) and to improve patient throughput and utilization of locations and human resources (doctors, nurses, receptionists). Some alternative scenarios in an attempt to determine optimal staff level were evaluated. These alternative approaches illustrate that vital improvement in LOS and throughput can be obtained by minor changes in shift hours and number of resources. Considering future changes in patient demand a scenario which reduces LOS and improves throughput is available in the paper. Significance: The Key Performance Indicators (KPIs) to determine and improve system performance in healthcare emergency departments consist of to reduce patient average length of stay (LOS), to improve patient throughput and resource utilization rates. Alternative scenarios and optimal staff levels are enhanced within the scope of this study.

İncele - MakaleAçık Erişim2012Scopus SJRQ1Automatic classification of power quality events and disturbances using wavelet transform and support vector machines
Eristi, H.; Demir, Y.
In this study, a new approach for the classification of power quality events is presented. Also, power quality disturbances, which occur in each phase of the power system after a fault event, are classified with the proposed system. In the proposed recognition system, three-phase voltage signals are used in order to identify the type of power quality events. Three-phase voltage signals are subjected to normalisation and segmentation processes. A wavelet transform method is used in order to obtain the distinctive features of event signals. An efficient feature vector, which represents the distinctive characteristics of three-phase event voltage signals and reduces data size, is extracted by applying the two-stage feature extraction process. Power quality event types are determined by using a support vector machine classifier. At the last stage of intelligent recognition system, types of power quality disturbances regarding each fault event are identified by doing a further analysis. Real power system data are used to evaluate the performance of the proposed approach. According to the obtained results, proposed intelligent recognition system classifies power quality event types with a high accuracy. The analyses and results also show that the proposed approach is efficient, reliable and applicable.

Eristi, Huseyin; Demir, Yakup
This paper presents a new power quality event classification technique using wavelet transform and logistic model tree. The proposed method uses the samples of three cycle duration of three line voltage of power quality events. The features of these samples are obtained by using the wavelet transform and a few different feature extraction techniques. The sequential forward selection method based a feature selection process is done to ensure good classification accuracy by selecting 20 better features from all 90 features generated from the wavelet transform coefficients. The obtained features are used to train a single logistic model tree. The feasibility of the proposed algorithm has been tested using real life power quality events. The result indicates that the feature selection based proposed method reliably classifies all types of power quality events with high accuracy.
