A single dose of 0.2 mg Brodifacoum was dissolved in Dimethyl Sulfoxide (DMSO) and was given orally to mature male rats. Spleen samples were collected under ether anesthesia after 24 h, 72 h, 14 days, and 30 days from the rats in the experimental groups and after 14 days from the rats in the control group. In this light microscope study, it was observed that the capsule, white pulp, and red pulp zones in the rat spleen were constructed normally and as their natural structures primary and secondary follicles (germinal center) they were few, and CD4 and CD8 lymphocytes were spherically structured. In the 24 h spleens of the rats, the diameters of germinal centers were expanded and deterioration of the structure of CD4 and CD8 cells was observed. Related to the increase in time (72 h and 14 days) it was determined that primary follicles increased in number and the diameters of germinal centers expanded. In addition to this, after30 days, the rate of CD4:CD8 of the brodifacoum applied rat spleens were approximately the rate of the control group, and the improvement of the structures of the cells was reported as an effect of regeneration. As a result of this study, it was found that Brodifacoum caused immunohistochemical abnormalities in the rat spleen, affected the morphological structure of CD4 and CD8 T lymphocytes and created an immune response in rats. It is thought that the obtained results will be a source for the studies on Brodifacoum.","PeriodicalId":249015,"journal":{"name":"Communications Faculty of Science University of Ankara Series C Biology Geological Engineering and Geophysical Engineering","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127260288","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 our study, the biological oxygen requirement of Çubuk Stream according to SWQR (BOD5: 22.5mg/l) IV. class, ammonium nitrogen element (NH4–N:2.34 mg/l) IV. class, nitrite nitrogen element (NO2–N: 0.035 mg/l) II. class, nitrate nitrogen element (NO3 –N:0.95 mg/l) Class I, according to phosphate value (PO4:0.075 mg/l) Class I and trace elements (Pb, Cd, Cr, Ni, Mn) values Class I. water quality. According to the ratio of NH4-N/PO4 (2.34/0.075=31.2 mg/l), the element that limits eutrophication in Çubuk Stream is P. Compared to previous studies, after the wastewater treatment plants established in the region, higher quality water is provided, especially in terms of NO3 and PO4. It has been determined that the nitrogen and phosphorus ratios are high because the region, which is dense in terms of organic matter, is close to industrial establishments.","PeriodicalId":249015,"journal":{"name":"Communications Faculty of Science University of Ankara Series C Biology Geological Engineering and Geophysical Engineering","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117006894","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}

It is one of the earliest herbaria of the Turkish Republic. The herbarium was part of the natural history collections of the school which also included insects, minerals, and fossils. The herbarium initially contained around 2500 specimens within 72 cardboard boxes. Additionally, specimens from this herbarium were sent to İstanbul University Department of Biology Herbarium (ISTF) and around 600 specimens to the herbarium of Royal Botanic Garden Edinburgh (E). In 2006, we received 567 plant specimens in five boxes. The plants were mainly collected from Bolu and neighboring provinces between 1953 and 1958. The herbarium collection contains one bryophyte specimen and three seedless vascular plants. The remaining taxa belong to gymnosperms and angiosperms. The herbarium labels were prepared both in Latin and Turkish. Majority of the specimens have identification up to family and genus level and a small number of them up to species level. This herbarium remained largely unknown to Turkish botanists. Therefore, we think it is valuable to provide detailed information about the history and the content of the herbarium. The information given here not only will contribute to our knowledge about the natural history collections of Turkey but also to the education history of the Turkish Republic.","PeriodicalId":249015,"journal":{"name":"Communications Faculty of Science University of Ankara Series C Biology Geological Engineering and Geophysical Engineering","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123737149","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}

Rhabdoviruses belong to a virus family which could infect a wide range of host organism. It is important to find new molecular diagnostic tools and primers for the identification of the viruses to be able to make the molecular identification process faster and reveal new forms of the virus. Rodents are the primary mammals group that can uncontrollably go in and out from quarantine regions. Therefore, in this study, 242 Apodemus spp. (wood mouse) and Myodes glareolus (bank vole) specimens collected from 16 localities in province Zonguldak, Çaycuma district were used to scan brain tissues to determine RABV using hemi-nested PCR. Also, to determine RABV a new primer pairs were designed using already published sequences. According to results, eight specimens were showed positive bands for RABV. Those eight sequences blasted. But the sequences did not match according to the Blast result. The designed primer pairs provide positive bands on electrophoresis for positive control so that the primer pairs are new and can be used for following studies. With this study it was also tested whether rodents are the potential carriers for RABV since they are primarily prey source for carnivores, and domestic animals.","PeriodicalId":249015,"journal":{"name":"Communications Faculty of Science University of Ankara Series C Biology Geological Engineering and Geophysical Engineering","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125337904","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}
