    This research was planned to present the effect of subsurface drip irrigation system on the yield and quality parameters of alfalfa of alone and mixture planted form in order to close the roughage deficit in the limited irrigable agricultural lands to the regional producer in Kirklareli conditions. The field experiment was carried out in a total of 24 plots with four replications in 2019 and 2020 according to the Factorial Arranged Random Blocks Trial Design on the land of Kirklareli Ataturk Soil Water and Agricultural Meteorology Research Institute. Two planting methods from alone planting (clover) and mixed planting consisting of alfalfa (Medicago sativa L.), Orchardgrass (Dactylis glomerata L.), perennial grass (Lolium perenne L.) and smooth brome (Bromus inermis L.) were used in the study. The ratios of the plants in the mixtures were determined as 25% for legume and 75% for poaceae. As the irrigation method, precipitation-based conditions, drip irrigation laterals placed at a depth of 20 cm in the soil and a subsurface drip irrigation system using drip irrigation laterals placed at a depth of 40 cm were preferred. In the research, the highest green grass yield (11.031,19 kg da(-1)) and the highest hay yield (1,880.51 kg da(-1)) was obtained from irrigated alone planting with laterals placed at a depth of 40 cm. In mixed planting, the highest yield of green (10.166,32 kg da(-1)) and hay was obtained in the plots irrigated with laterals placed at a depth of 20 cm. In both planting forms, the lowest yield was obtained from the treatments based on precipitation. According to the data obtained; Considering the green grass and hay yields, crude protein, crude cellulose, ADF, NDF and raw ash ratios in planted alone alfalfa plots; Irrigation with laterals placed at a depth of 40 cm in the soil, and irrigation with laterals placed at a depth of 20 cm in mixed planting can be recommended

    Objective: Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma among adults and is characterized by heterogeneous clinical, immunophenotypic, and genetic features. Different mechanisms deregulating cell cycle and apoptosis play a role in the pathogenesis of DLBCL. Growth arrest DNA damage-inducible 45 (GADD45γ) is an important gene family involved in these mechanisms. The aims of this study are to determine the frequency of GADD45γ methylation, to evaluate the correlation between GADD45γ methylation and protein expression, and to investigate the relation between methylation status and clinicopathologic parameters in DLBCL tissues and reactive lymphoid node tissues from patients with reactive lymphoid hyperplasia. Materials and Methods: Thirty-six tissue samples of DLBCL and 40 nonmalignant reactive lymphoid node tissues were analyzed in this study. Methylation-sensitive high-resolution melting analysis was used for the determination of GADD45γ methylation status. The GADD45γ protein expression was determined by immunohistochemistry. Results: GADD45γ methylation was frequent (50.0%) in DLBCL. It was also significantly higher in advanced-stage tumors compared with early-stage (p=0.041). In contrast, unmethylated GADD45γ was associated with nodal involvement as the primary anatomical site (p=0.040). Conclusion: The results of this study show that, in contrast to solid tumors, the frequency of GADD45γ methylation is higher and this epigenetic alteration of GADD45γ may be associated with progression in DLBCL. In addition, nodal involvement is more likely to be present in patients with unmethylated GADD45γ. © 2015 Turkish Society of Hematology. All rights reserved

    Objective:The aim of this study is to compare the efficacy and complications of holmium laser and pneumatic lithotripsy used in the ureterorenoscopic treatment of proximal ureteral stones.Materials and Methods:Data of 638 patients, who underwent ureterorenoscopy (URS) due to proximal ureteral stones in different centers, were obtained from patient files. The patients were divided into two groups according to the type of lithotripter used: group 1; laser lithotripter (n=324; 50.8%) and group 2; pneumatic lithotripter (n=314; 49.2%). URS was considered successful upon determination stone-free status with the imaging methods after treatment. The effectiveness and the complications of holmium:yttrium-aluminum-garnet laser and pneumatic lithotripsy were compared.Results:The total success rate of URS was 82.6% and the complication rate was 8.1%. The mean age of patients was similar between the groups; however, the body mass index values, stone surface area and stone Hounsfield unit were significantly higher in group 1. Although the mean operative time, complication rate and the mean length of hospital stay were similar between the groups; the URS success and postoperative ureteral J stent use rates were significantly higher in group 1 and the push-back rate was significantly higher in group 2.Conclusion:If laser lithotripsy is available in a clinic, we believe that it is better to use it as the first option in the treatment of proximal ureter stones. However, considering that it is not easy to access laser lithotripters due to their high cost in Turkey, pneumatic lithotripters may be an effective and inexpensive alternative that can also be safely used in these cases

    Translation revision is an essential part of professional translation, andit has beenone of the biggest workloadsof translation companies. However, far too little attention has been paid to itwithinthe relevant literature on translation studies.To fillthisgap, this study aimsto analyzethe translation revision policies of translation companies in Turkey through a questionnaire developed by Rasmussen &Schjoldager (2011). For this study,the questionnaire was adapted and slightly modifiedto reflect the specific situation in Turkey. The questionnaire was answered by 15 revisersand/or managers of translation companies in Turkey, specifically in three big cities (including İstanbul, Ankara, İzmir). The dataderived from the questionnaireshow the revision types that translation companies mostly prefer. The answers of the respondents in translation companies offer a brief insight into the parameters that translation companies consider during the revision process. The remarks of the respondents also highlighted the scarcity of the revision training within translation companies.In addition,the answers of the respondents showed that they give importance to the problems of the transfer and content of the text as well as language and presentation as suggested by Mossop (2007, 2014). This study, in short,tries to reflect a view on the current status of translation revision in Turkeythrough 15 translation companies
