Forty Wistar albino rats were randomly divided into four groups: control, ischemia, IR and Mesna. Ischemia period was executed by clamping superior mesenteric artery (SMA) for 2 h and then reperfusion was permitted by removing the clamp from SMA for 2 h.

Additionally, tumor vs stromal cell expression of the target genes was analyzed from publicly available patient expression datasets. Finally, the correlation between CD39 and CD73 expression with patient prognosis was analyzed via TCGA datasets. \u0000Results: In CRC cell lines CD39 found to be not expressed at all while CD73 was expressed extensively in most cell lines via WB and RT-CR analyses. Patient microarray expression data confirmed the results from CRC cells lines that CD39 expression was very low in epithelial/tumor cells relative to other stromal cell types yet CD73 was expressed abundantly in every cell type within patient tumor samples. Interestingly, CD39 expression in patient tumors was correlated with favorable prognosis while CD73 expression was associated with worse prognosis. \u0000Conclusion: Although CD39 and CD73 are related enzymes involved in extracellular purinergic signaling, their expression patterns in tumor cells and prognostic effects in patients show opposing outcomes. Therefore, better insights in understanding the functional involvement of purinergic ecto-enzymes in colorectal tumor development is needed via further mechanistical studies.","PeriodicalId":23163,"journal":{"name":"Trakya University Journal of Natural Sciences","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81324815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a novel ensemble technique was proposed for the prediction of PM2.5 concentration in cities with high traffic noise using traffic noise as an input parameter. Air pollutants concentration (P), meteorological parameters (M) and traffic data (T) simultaneously collected from seven sampling points in North Cyprus were used for conducting the study. The modelling was done in 2 scenarios. In scenario I, PM2.5 was modelled using 4-different input combination without traffic noise as input parameter while in scenario II, traffic noise was added as an input variable for 4 input combinations. The models were evaluated using four performance criteria including Nash-Sutcliffe efficiency (NSE), root mean square error (RMSE), correlation coefficient (CC) and bias (BIAS). Modelling PM2.5 with combined relevant input parameters of P, M and T could improve the performance of the model developed with only one set of the parameters by up to 12, 17 and 29% for models containing only P, M and T respectively. All the models in scenario II have demonstrated high prediction accuracy than the corresponding model in scenario I by up to 12% in the verification stage. The SVR-E could improve the performance accuracy of the single models by up to 17% in the verification stage.","PeriodicalId":23163,"journal":{"name":"Trakya University Journal of Natural Sciences","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79641240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was conducted in Edirne central district between July 2017 and July 2018 to identify important vector mosquito species, determine their seasonality and distribution pattern in general terms. Larvae, pupae, and adults were collected from areas assessed as being particularly suitable for medically important species included in the genus of Aedes, Culex, and Anopheles. In addition to the foci naturally found in the areas, ovitraps placed in the proper points were also used. As a result, 3155 female and 353 male mosquitoes belonging to 13 species of 5 genera were obtained. Among these species, Anopheles sacharovi (the primary vector of malaria in Turkey) and Culex pipiens s.l. (the primary vector of West Nile Fever) has been recognized as a public health threat to the province. An. sacharovi was represented at a very low population level, while Cx. pipiens s.l. was determined as the most common and dense species in the study area. Known to have a high preference for warmer climate compared to members of the Anopheles maculipennis s.l., An. sacharovi has the risk of increasing its population in the region with possible global warming in the future. The importance of this risk increases even more since rice production is widespread especially in Edirne and this species can use the paddy fields as an effective breeding place. While Aedes caspius was commonly encountered, Ae. albopictus was not found during the field observation and ovitrap controls.","PeriodicalId":23163,"journal":{"name":"Trakya University Journal of Natural Sciences","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72569807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
