A field experiment was conducted to evaluate yield, quality, and other characteristics in selected lines of crested wheatgrass (Agropyron cristatum L. Gaertn.) at Ataturk University Agriculture Faculty Research Farm under unirrigated conditions during 2006, 2007, 2008, 2009, 2010, and 2011 in Eastern Turkey. The research was established in 2006 as a randomized complete block with three replications. Lines AC1 (Reg. No. PL-12, PI 667083), AC2 (Reg. No. PL-13, PI 667084), AC23 (Reg. No. PL-14, PI 667085), AC29 (Reg. No. PL-15, PI 667086), AC37 (Reg. No. PL-16, PI 667087), AC39 (Reg. No. PL-17, PI 667088), AC65 (Reg. No. PL-18, PI 667089), AC66 (Reg. No. PL-19, PI 667090), AC83 (Reg. No. PL-20, PI 667091), AC107 (Reg. No. PL-21, PI 667092), AC113 (Reg. No. PL-22, PI 667093), AC121 (Reg. No. PL-23, PI 667094), AC125 (Reg. No. PL-24, PI 667095) and Tohum Islah population (Reg. No. PL-11, PI 667082) (control) were evaluated for dry matter yield (DMY), seed yield (SY), straw yield (SWY), crude protein content (CPC), crude protein yield (CPY), stem number, plant height, and fertile tiller ratio. Forage DMY and SY increased over the first 4 yr, but the yields decreased due to the aging of the crested wheatgrass stand in the subsequent year. There were significant differences for lines in all variables, except for SWY and CPC. Particularly, lines AC1, AC23, AC29, AC37, AC39, AC65, AC66, AC107, and AC121 in DMY; AC1, AC37, AC83, AC107, AC113, AC121, and AC125 in SY; and AC23, AC39, and AC113 in CPY showed significant improvement compared with the original parent material. The results of DMY, SY, and CPY show that selection studies were effective. Selected lines will be useful for breeding studies and livestock production.

Yildiz, M.; Kayim, M.; Akin, S.
In this study, anesthetic effects of five different concentrations of 2-phenoxyethanol (0.2, 0.3, 0.4, 0.5 and 0.6 ml/L) and clove oil (0.50, 0.75, 1.00, 1.25 and 1.50 ml/L) on rainbow trout (Oncorhynchus mykiss) were studied at temperatures 7, 13 and 18 degrees C. For this purpose, 900 fish (39.08 +/- 1.13 g and 15.48 +/- 0.21 cm) were used in the experiment. Induction time of 2-phenoxyethanol and clove oil varied between 1.05 and 3.36 min at all concentrations, except for 0.2 ml/L (for 2-phenoxyethanol only) and at every temperature application. Full recovery time occurred between 2.44 and 7.14 min for 2-phenoxyethanol and 3.23 - 6.11 min for clove oil. It was found that full recovery times significantly increased with increase in 2-phenoxyethanol concentrations (r(2)=0.81). The same increasing trend was observed in clove oil, but the increase was not strong compared to 2-phenoxyethanol (r(2)=0.21). On the other hand, full induction times of 2-Phenoxyethanol and clove oil significantly declined with the increase in concentrations (r(2)=0.74; r(2)=0.84 for 2-phenoxyethanol and clove oil, respectively). Based on the ideal induction (less than 3 min) and recovery (less than 5 min) time criteria, it can be suggested that the most appropriate concentrations for rainbow trout were 0.3, 0.4 and 0.5 ml/L for 2-phenoxyethanol and 0.50, 0.75 and 1.00 ml/L for clove oil.

Adiloglu, Ali Kudret; Gönülates, Nurettin; Isler, Mehmet; Senol, Altug
The systemic effects of bioactive peptides which are produced by the fermentation of milk via the microorganisms found in kefir have been the subject of interest in recent years. Bioactive peptides activate innate immunity by stimulating macrophages, increasing phagocytosis, augmenting NO and cytokine production and boosting the lumen levels of IgG and 19A(+) B-lymphocytes. The aim of the present study was to determine the serum cytokine profiles of healthy volunteers after kefir consumption to evaluate helper T (TH) cell polarization and to bring out the effects on native and allergic immune responses. The study was designed as a prospective and self-controlled study. A total of 18 healthy volunteers (age range: 20-40 yrs, mean age: 35.5 +/- 7.38 yrs) from a university hospital staff were recruited to the study, with the approval of ethical board and informed consent. The body mass indices of all participants were between normal range (20.10-25.70 kg/m(2)). After two weeks of a diet free from fermented products, the participants consumed 200 mL kefir daily, for six weeks. Kefir product was prepared by using kefir starter culture (Danisco Biolacta Sp - 05223B 10001, Poland) which contains Lactobacillus spp., Leuconostoc spp., Lactococcus lactis ssp. lactis and Streptococcus termophilus, an overnight incubation at 26 C, and consumed freshly. Fasting blood samples of subjects were collected just before kefir use (0th week), at the end of the 3rd and 6th weeks of kefir consumption, and three weeks after cessation of kefir usage (9th week). Serum TNF-alpha, IL-1, IL-5, IL-8 and TGF-beta levels were measured by using commercial ELISA kits (BioSource, Belgium and Invitrogen, USA). Hemoglobin, serum creatinine and ALT levels of all subjects were also determined for follow-up. All volunteers completed the study period without any problem and declared no complaint. Hemoglobin, creatinine and ALT levels did not change with kefir consumption. Serum IL-8 levels were decreased at 3rd and 6th weeks (p<0.001) and were at low levels at 9th week (p=0.005) when compared with baseline levels (0th week). Serum IL-5 levels were increased at 3rd week (0th-3rd weeks; p=0.01) and decreased by a rebound effect at 9th (6th-9th week p=0.003). TNF-alpha levels were increased with kefir consumption (p=0.046) but the increase was insignificant in paired comparisons and the level was borderline between 0th and 6th weeks (p=0.013). IL-5 and TNF-alpha levels returned to their original levels (0th week) at 9th week. Levels of the other cytokines (IL-1 and TGF-beta) did not change significantly with kefir usage. These results indicated that kefir use increased polarization of the immune response towards TH, type and decreased TH, type response and accordingly allergic response. The decrease in IL-8 level due to kefir use, might control the inflammatory response by suppressing neutrophil chemotaxis and activation. On the other hand it was also concluded that increased IL-5 might stimulate secretory IgA at gastrointestinal mucosa leading to a more efficient immune response in the intestinal lumen.

BackgroundPatients with diabetes mellitus (DM) are at high risk of left ventricular (LV) dysfunction. A reduction of coronary flow reserve (CFR) has been demonstrated in diabetic patients without coronary artery stenosis. In this study, we investigated the association between LV myocardial diastolic and systolic functions and the CFR in newly diagnosed diabetic patients in the absence of coronary artery disease. MethodWe studied 88 patients (mean age 4910years) with newly diagnosed DM and 40 healthy control subjects (mean age 509years). All subjects underwent transthoracic echocardiography. The myocardial performance index (MPI) was determined by using pulsed-wave Doppler. The CFR was calculated as the hyperemic to resting coronary diastolic peak velocities ratio. ResultsPatients with diabetes had significantly longer mitral E-wave deceleration time and higher MPI value than control group (P=0.023 and P<0.001, respectively). The mean CFR was lower in diabetic patients compared with controls (P=0.001). The MPI was significantly correlated with CFR (r=-0.371, P<0.001), LV ejection fraction (r=-0.274, P=0.018) E/A ratio (r=-0.244, P=0.024), and glycosylated hemoglobin (HbA1c) (r=0.476, P<0.001). Multivariate regression analysis showed that MPI was independently associated with CFR (=-0.292, P<0.0001) and HbA1c level (=0.372, P<0.0001). ConclusionsThe MPI was independently associated with CFR in newly diagnosed diabetic patients. The decrease in CFR may cause LV systolic and diastolic dysfunction in asymptomatic diabetic patients.

In present-day societies, the notion of leisure time can be considered in quite different meanings. An emerging prominent meaning of interest would deal with leisure time as a space of consumption. Numerous studies have explored the notion in relation to different factors. This study deals with the topic of leisure time in relation to social gender patterns of consumption by means of a discourse analysis conducted on two magazines for men and women respectively. The results showed that in both magazines, the identities of women were constructed through the codes of a male-dominated discourse and were idealized by images that comply with the viewpoint of men.

Bingöl, Ozkan; Ekinci, Murat
Although studies on the palm recognition systems achieving are high performance ratios, hygiene problems in contact systems and change of hand pose in contactless systems were encountered. 3D recognition systems is proposed for solve these problems. But, these systems did not find the opportunity to become widespread because of expensive technologies and low scanning speed. In this study was proposed a method for detemined pose variations of palmprint using stereo cameras and transferring patterns that to be used for recognition to 2D space. Thus, both a non-contact system will be obtained and can be used properties of strong 2D recognition systems.

Sezer, Ismet; Bilgin, Atilla
This study is concerned with investigating experimentally the effects of methanol and Methyl tert-Butyl Ether (MTBE) blending to base gasoline on the performance CO emissions and fuel cost of a spark ignition (SI) engine. The fuel blends were prepared by addition 5, 10, 15, and 20 vol % of methanol and MTBE with a specified amount of base gasoline. The methanol- and MTBE-gasoline blends were designated as M5, M10, M15, M20, and MTBE5, MTBE10, MTBE15, MTBE20, respectively. Experiments were conducted under various engine speeds, spark timings (STs), and compression ratios (CRs). The engine was operated under wide-open throttle conditions. The results of the study showed that the M5 and MTBE10 blends yield the best engine performance in terms of the brake mean effective pressure (bmep), while the M20 and MTBE15 blends are the best performers in terms of brake thermal efficiency (bte). Moreover, M20 and MTBE10 blends give the minimum CO emission values. The economical analysis performed in the study is based on both the current blending fuel prices in Turkey and brake specific fuel consumption (bsfc) of the engine while using gasoline, methanol-gasoline, and MTBE-gasoline blends. It was obtained that, in contrast to the improvement of engine performance, efficiency and CO emissions, methanol and MTBE blends caused increases in fuel costs because of the expensive methanol and MTBE prices in Turkey. Uncertainty analysis was also performed in this study, and it was found that; the uncertainties in the measurement devices do not have noticeable influences on the variations of engine characteristics.

Cakir, Tufan
A three-dimensional backfill-structure-soil/foundation interaction phenomenon is simulated using the finite element method in order to analyze the dynamic behavior of cantilever retaining wall subjected to different ground motions. Effects of both earthquake frequency content and soil-structure interaction are evaluated by using five different seismic motions and six different soil types. The study mainly consists of three parts. In the first part, following a brief review of the problem, the finite element model with viscous boundary is proposed under fixed-base condition. In the second part, analytical formulations are presented by using modal analysis technique to provide the finite element model verification, and reasonable agreement is found between numerical and analytical results. Finally, the method is extended to further investigate parametrically the effects of not only earthquake frequency content but also soil/foundation interaction, and nonlinear time history analyzes are carried out. By means of changing the soil properties, some comparisons are made on lateral displacements and stress responses under different ground motions. It is concluded that the dynamic response of the cantilever wall is highly sensitive to frequency characteristics of the earthquake record and soil-structure interaction.

Serotonin is a monoamine neurotransmitter and biochemically derived from tryptophan. The present paper examines the in vitro antioxidant and radical scavenging capacity of serotonin using different in vitro methodologies. For the determination of antioxidant activity of serotonin, 1,1-diphenyl-2-picryl-hydrazyl free radical (DPPH) scavenging, 2,2́-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radical scavenging activity, total antioxidant activity determination by ferric thiocyanate, total reducing ability determination by Fe3+-Fe2+ transformation method, superoxide anion radical scavenging by riboflavin-methionine-illuminate system, H2O2 scavenging and ferrous ions (Fe +) chelating activities of serotonin were performed. Also, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), α-tocopherol and trolox, a water-soluble analog of α-tocopherol, were used as the reference antioxidant radical scavenger compounds. Serotonin completely inhibited lipid peroxidation of a linoleic acid emulsion at 15 μg/mL concentration. On the other hand, the above mentioned standard antioxidants displayed inhibition of 92.2, 99.6, 84.6 and 95.6% on peroxidation of linoleic acid emulsion, respectively at the 45 μg/mL concentration. In addition, serotonin was effective in DPPH· scavenging, ABTS•+ radical scavenging, superoxide anion radical scavenging, H2O2 scavenging, ferric ions (Fe3+) reducing power and metal chelating on ferrous ions (Fe+) activities. Also, those various antioxidant activities were compared to BHA, BHT α-tocopherol and trolox as references antioxidant compounds.
