Item A botanical excursion around Köyceğiz and DalamanKARAMANOĞLU, KâmilItem A NEW RARE MACROPHYTE RECORD FROM SW ASIA AND ECOLOGICAL CONDITIONS AT ITS HABITAT(Ankara Üniversitesi Fen Fakültesi, 2021) Yaprak, Ahmet Emre; Biyoloji; Fen Bilimleri EnstitüsüAldrovanda vesiculosa L. is a cosmopolitan but very rare carnivorous aquatic angiosperm species from the family Droseraceae. The species was widespread and more common few decades ago but unfortunately it is being extinct in so many former distribution areas due to aquatic pollution and eutrophication. During the field trip to Karakuyu Lake we recognized a remarkable free-floating plant, after detailed investigation we identified the specimens as Aldrovanda vesiculosa which is a new record from Turkey and also SW Asia. In this publication, we provided detailed description of the species based on Turkish specimens, its habitat description, water physiochemical attributes, co-occurring macrophyte species list and botanical illustration of the species.Item A new record of Ophiobolus riess for TurkeySELÇUK, Faruk; GÜNDOĞAN, Tuğba; AKATA, IlgazItem A phytosociological research in the Belgrad forestYALTIRIK, F;AKMAN, Y;KETENOĞLU, OItem A Phytosociological Research on the Vegetation of the Bolu MountainsAKMAN, Yıldırım ;YURDAKULOL, EnderItem A Phytosociological Research on the Vegetation of the Semen Mountains (Bolu)AKMAN, Yıldırım ;YURDAKULOL, Ender ;DEMİRÖRS, MehmetItem A Phytosociological Study in the Vicinites of Çamlıdere Çamkoru and PeçenekAKMAN, Y. ;AYDOĞDU, Y.Item A study on EPS production by a microorganism exposed to copper(II) ionsKOÇBERBER KILIÇ, NurItem ACCUMULATION OF CR6+, PB2+ AND CD2+ AND ULTRAVIOLET RADIATION ALTER METHYLATION AND GENOMIC DNA STATUS IN RAMALINA FARINACEAE(Ankara Üniversitesi Fen Fakültesi, 2021) Aras, Emine Sümer; Biyoloji; Fen FakültesiIn this study was aimed to determine the genotoxic effect of Ramalina farinacea lichen species against stress sources at the molecular level. After applying three different heavy metals (Pb2+, Cd2+, and Cr6+) to the R. farinacea, the extent to which the lichen sample absorbed these metals was determined by Flame Atomic Absorption Spectroscopy. RAPD and MSAP-AFLP assays were also used to determine the status of DNA damage. The heavy metal analysis showed that R. farinacea had high levels of Pb2+, Cd2+, and Cr6+ content. According to the results obtained from molecular analyses, band changes were observed against seven primers heavy metal stresses and three primers against UV stress. An increase in Genomic Template Stability (GTS) was determined during the time in R. farinacea treated with all heavy metal concentrations. The effect of UV radiations in R. farinacea revealed the highest polymorphism and the lowest GTS rate depending on the dose. Among all methylation combinations, Type II was found to show altered in R. farinacea in response to Pb2+, Cd2+, and Cr6+ contents and UV radiations. R. farinacea can be used at the molecular level as a biomarker of suitable genotoxic effect. This is the first study to reveal DNA damage against stress sources using a sample of R. farinacea lichen species.Item Age determination of fossils collected from Karabük, Safranbolu, Bulak river area by using amino acid racemization methodKARA, Sibel; ÖZDEMİR, Tahir; ALTUNER, Ergin MuratItem Allergenic compounds in honey bee productsSİLİCİ, SibelItem Alteratıons of aldose reductase actıvıty by ındole-3-carboxaldehyde derıvatıves(Ankara Üniversitesi Fen Fakültesi, 2021) Yıldırım, Özlem; Biyoloji; Fen FakültesiIn diabetic conditions, aldose reductase (AR, EC 1.1.1.21) activity is significantly increased in lens, kidney and nerve tissues. Mainly in ocular and neural tissues increased levels of sorbitol is associated with diabetic complications such as retinopathy, nephropathy, neuropahty, cataract formation and also tissue damage via increased reactive oxygen speices. Recently, there are many studies that show the relationship between this enzyme family and cancer. Aldose reductase is important for the pathway and in turn has been a potential target for drug design. Great number of aldose reductase inhibitors (ARIs) are used for prevention or delay of these diabetic complications and cancer. However, effective ARIs which has benefits in diabetic complications are still under investigation. In this study aldose reductase was partially purified from bovine lens and the inhibitory effects of 16 different indol-3-carboxyaldehydederivatives on aldose reductase enzyme activities were examined by kinetic assays. These results suggested that N'-[(5-bromo-1H-indol-3-yl)methylidene]pyridine-4-carbohydrazide showed that the highest inhibitory activity on AR.Item Althenıa orıentalıs (potamogetonaceae) ın turkey: habıtat condıtıons, morphology and anatomy(Ankara Üniversitesi Fen Fakültesi, 2020) Bayındır, Necati; Other; OtherAlthenia F.Petit is a submerged aquatic plant genus, which is represented by two species in the world. Althenia species are found mainly in brackish water lagoons and in salt lakes. The genus has only one species in Turkey, Althenia orientalis (Tzvelev) García-Mur. & Talavera which was collected from Turkey in 1959 and published in 1975. Since then, it could not be collected again and was assessed as extinct in Turkey. We performed field studies to collect the species in May 2017 and June 2017. We managed to find the species in its original locality. We measured chemical and physical properties of the water bodies it is growing. Additionally, we provide the stem anatomy of the species based on Turkish material for the first time. The single locality of the species in Turkey is a hypersaline lagoon lake (Lake Tuzla, Adana). Only dense Ruppia maritima L. population accompanies the species. Althenia orientalis grows in slightly alkaline and warm waters. The population size is small, covering approximately 500 m2 area. The plants future presence is threatened by severe human pressure (i.e. pollution due to construction waste deposits and dense agricultural activities).Item An investigation of pollen grain thermal diversity on species levelMUJTABA, Muhammad; KAYA, Murat; CETER, TalipItem An investigation of Rabies virus existence on rodents by using new PCR primer pairs(Ankara Üniversitesi Fen fakültesi, 2022) Günkan, Tugce; Other; OtherZoonotic diseases are the infections to be carried between human and other vertebrates. 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.
