Biomarkers of ecotoxicological oxidative stress in an urban environment: using evergreen plant in industrial areas
Öztetik, Elif (Springer, 2015)Plants react to air pollution by increased production of reactive oxygene species and oxidative stress, which triggers multiple defense mechanisms. In this study, some parameters that serve as biomarkers for antioxidative ... -
Characterization of Glutathione S-Transferases From Needles of Pinus Brutia Ten. Trees
Öztetik, Elif; İşcan, Mesude (Parlar Scientific Publications (PSP), 2013)Glutathione S-transferases (GST, E.C. 2.5.1.18) are generally dimeric and multifunctional enzyme family which catalyse the nucleophilic attack of the glutathione on lipophilic compounds with electrophilic centres. Since ... -
Early antioxidative defence responses in the aquatic worms (Limnodrilus sp.) in Porsuk Creek in Eskisehir (Turkey)
Öztetik, Elif; Çiçek, Arzu; Arslan, Naime (Sage Publications Inc, 2013)Certain oligochaeta specimens have been universally applied as bioindicators to reflect the organic and inorganic pollution in rivers and play a major role in the decomposition of pollutants. The aim of this study was to ... -
