Feasibility And Assessment Of The Phytoremediation Potential Of Duckweed For Triarylmethane Dye Degradation With The Emphasis On Some Physiological Responses And Effect Of Operational Parameters, Samaneh Torbati
Turkish Journal of Biology
Phytoremediation is a low-cost and effective technology that removes pollutants, such as dye-containing effluents, from the environment through the use of plants. In the present study, the potential of Lemna minor L. for decolorization and degradation of the triarylmethane dye malachite green was investigated. The results revealed that the decolorization ability of the plant species is as high as 88%. The effect of some operational parameters (initial dye concentration, temperature, pH, and amount (weight) of plant) on the efficiency of biological decolorization process was determined. The metabolic fate of the dye was proposed by identifying 8 intermediate compounds produced during …
Activity Of Antioxidant Enzymes In The Liver Of Wild Boars (Sus Scrofa) From A Selenium-Deficient Area Depending On Sex, Age, And Season Of The Year, Dorota Jankowiak, Renata Pilarczyk, Radoslaw Drozd, Bogumila Pilarczyk, Agnieszka Tomza-Marciniak, Gabriela Wysocka, Izabella Rzad, Arleta Drozd, Jaroslaw Kuba

The aim of this study was to compare the activity of antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), and total and selenium-dependent glutathione peroxidase (total GSH-Px and Se-GSH-Px) in the liver of wild boars (Sus scrofa) selected from a selenium-deficient area with respect to season of the year, sex, and age. Only season had a significant effect on liver Se content. Liver selenium concentration in the wild boars was highest in spring (0.292 µg/g wet weight) and lowest in winter (0.185 µg/g wet weight) (P < 0.05). The highest mean activity of total GSH-Px, Se-GSH-Px, and CAT (404.0, 309.9, and 1170.0 U/mg protein, respectively) was found in the spring season, and the respective highest mean activity of SOD was found during autumn (31.5 U/mg protein). Females showed markedly higher mean activities of total GSH-Px (388.2 and 314.7 U/mg protein) and CAT (1151.0 and 765.8 U/mg protein) compared to males. In comparison to other groups of animals, those aged between 1 and 1.5 years were characterized by higher mean activity of total GSH-Px and Se-GSH-Px, and those over 2 years of age showed higher activity of CAT and SOD. The analysis showed that the strongest oxidative stress and the greatest risk of peroxidative damage to the liver occurred during the winter.

Acrylamide (AA) has neurotoxic, mutagenic, and genotoxic effects in humans and experimental animals. Fruit consumption is important for human health, because fruits are the source of many nutrients such as vitamins, minerals, carotenoids, dietary fiber, and phytonutrients. Many agricultural products provide natural melatonin in the diet. At the onset of the study, rats were weighted and randomly divided into four groups each containing 10 rats as follows: group 1: control (fed with normal diet and normal drinking water); group 2: apricot (fed with a daily diet with 5% apricot and normal drinking water); group 3: AA (administered daily acrylamide at …

Adriamycin, an anticarcinogenic agent, causes excessive production of reactive oxygen species (ROS). These radicals may affect antioxidant defense systems. The present study was designed to investigate the effects of melatonin on antioxidant enzyme activities and vitamin C in Adriamycin-treated rats. In the current study, rats were divided into three groups: control, Adriamycin, and melatonin+Adriamycin groups. The control group was intraperitoneally injected physiological saline (0.9%) as a placebo. The Adriamycin and melatonin+Adriamycin groups were administered Adriamycin (25 mg/kg body weight). The melatonin+Adriamycin group was pretreated with melatonin (0.5 mg/kg body weight). Vitamin C concentration and catalase (CAT), superoxide dismutase (SOD), glutathione …
