The Biochemical And Histoanatomical Response Of Some Woody Species To Anthropic Impact In Suceava County, Romania, Elena Ciornea, Irina Boz, Elena Ionel, Sabina Ioana Cojocaru, Gabriela Dumitru
Turkish Journal of Biology
The use of extractive mining technologies in various areas of Suceava, Romania (C?limani Mountains - sulfur, Tarni?a-Ostra - copper and barite, and Crucea-Botuşana - uranium) has resulted in the accumulation of surplus chemicals with direct action on the ecosystem. The aim of this study was to analyze the possible damage on some woody species (Picea abies L., Populus tremulaL., Salix alba L., Betula verrucosa Ehrh.,and Larix decidua Mill.) and their adaptive and phytoremediation capacity through the biomarkers of oxidative stress and histoanatomical observations. Thus, we determined the total soluble protein concentration and superoxide dismutase, catalase, and peroxidase activities. Cross-sections of …
Genome-Wide Distribution Of Superoxide Dismutase (Sod) Gene Families In Sorghum Bicolor, Ertuğrul Fi̇li̇z, Hüseyi̇n Tombuloğlu
Genome-Wide Distribution Of Superoxide Dismutase (Sod) Gene Families In Sorghum Bicolor, Ertuğrul Fi̇li̇z, Hüseyi̇n Tombuloğlu
Turkish Journal of Biology
Superoxide dismutases (SODs) are critical enzymes protecting cells against toxic superoxide radicals. To date, 3 types of SODs have been identified: Cu-ZnSODs, Fe-MnSODs, and NiSODs. In this study, a genome-wide analysis was performed in Sorghum bicolor to characterize SOD genes and proteins. Using several bioinformatics tools, we characterized a total of 8 SOD genes from the Sorghum genome. Gene structure, chromosomal distribution, tissue specific expression, conserved domain, and phylogenetic analyses of SOD genes were carried out. Additionally, 3-dimensional structures were determined and compared within each SbSOD protein. Chromosomal distributions revealed that the highest number of SOD genes was on chromosomes …

The aim of the study was to examine changes in Cu?Zn superoxide dismutase (SOD), catalase (CAT), their gel electrophoresis profiles, glutathione reductase (GR) activity, amount of glutathione (GSH), and the activity of glutathione S-transferase (GST) - phase II biotransformation enzyme in the midgut tissue of gypsy moth (Lymantria dispar L. (Lepidoptera: Lymantriidae)) larvae after ghrelin treatment. Four subpicomolar injections of ghrelin (0.3 pmol) or physiological saline (control) were applied every 24 h. The SOD, CAT, GR, GST activity, and amount of GSH were higher in the ghrelin-treated group than in the control. Electrophoresis gel bands of SOD and CAT had …

This study was conducted to investigate the histopathological and biochemical effects of midazolam and etomidate, which are intravenous anesthetics used in surgical operations, on rat liver. There were 3 study groups each consisting of 9 animals: the control, midazolam, and etomidate groups. Midazolam and etomidate were administered 10 times with 1-day intervals. At the end of the study, tissues were taken for histological examination and biochemical analysis. We determined superoxide dismutase (SOD), catalase (CAT), and malondialdehyde (MDA) levels in the liver. There was a slight increase in MDA level in the midazolam-exposed group when compared with the controls, and this …
