Diabetes induced by streptozotocin (50 mg/kg body wt, i.p.) in the rats substantially increased the plasma glucose and malondialdehyde levels along with corresponding decrease in the antioxidants levels. Supplementation of vitamin E (200 mg/kg body wt., ip) for 5 weeks resulted in non-significant decrease in the blood glucose levels but plasma malondialdehyde levels were reduced to below normal...

raspberry waste, obtained from two cultivars, meeker (erm) and willamette (erw) was subjected to evaluation antioxidants and antitumour activities as a potential source of phenolics. some phenolic acids and flavonoids were identified and quantified by hplc. antioxidant activity was tested by measuring ability to scavenge dpph• and •oh by esr spectroscopy. ic50dpph• varied from 0.67 for erm to 0...

This study was performed on 2-year-old seedlings of the Pazar-20 tea clone pots in 2014-2015. Twelve different bacterial isolates (Bacillus atrophaeusRC11, Bacillus megateriumRC07, megaterium42/4, megaterium21/3, Pseudomonas fluorescensRC77, fluorescens 8/4, fluorescens8/6, fluorescens9/7, subtilisRC63, subtilis 39/3, subtilis36/10, subtilisRC521), which were isolated from acidic soils and char...

Nitric oxide (NO) is involved in numerous physiological and stress responses in higher plants. Tomato is one of the most important vegetable crops in the world and previously it has been reported that salinity induced an oxidative stress affecting its redox and NO homeostasis. Using tomato plant exposed to 120 mM NaCl, it was studied whether the exogenous application of NO could ameliorate the ...

The possible involvement of activated oxygen species in the mechanism of damage by NaClstress was studied in leaves of two varieties of pea (Pisum sativum L.) cv. EC 33866 and Puget. Thelevel of lipid peroxidation, enzyme activity of superoxide dismutase (SOD, EC 1.15.1.1), ascorbateperoxidase (APX, EC 1.11.1.11), glutathione reductase (GR, EC 1.6.4.2), dihydroascorbate reductase(DHAR, 1.8.5.1)...

Iron nanoparticles (Fe NPs) have a wide array of biological and medical applications. In agriculture, Fe NPs has the potential to be used as an innovative technique alleviate deficiency in various crops, such grape. However, effect on alleviating stresses grapevine are unexplored. The aim this study was evaluate efficiency protecting ‘Asgari’ seedless grape (Vitis vinifera L.) against oxidative...

AIM to study the activity of antioxidant enzymes and to evaluate an intensity of prooxidant processes in sarcoma 37 (S37) cells during tumor development and under influence of sodium dichloroacetate (SDA). METHODS Activity of total superoxide dismutase (SOD), SOD isoforms, catalase (Cat), glutathione peroxidase (GP), and glutathione reductase (GR), as well as content of reduced glutathione (G...

This study investigated effect of repeated exposure to low doses of diuron in gilthead sea bream by measuring the activities of the following antioxidant enzymes: Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), glutathione reductase (GR), glutathione transferase (GST), and DT-diaphorase (DTD). Examination of the lipid peroxidation (malondialdehyde contentMDA) and gluco...

Superoxide dismutase (SOD), glutathione peroxidase (GPX), glutathione S-transferase (GST) and glutathione reductase (GR) play crucial roles in balancing the production and decomposition of reactive oxygen species (ROS) in living organisms. These enzymes act cooperatively and synergistically to scavenge ROS, as not one of them can singlehandedly clear all forms of ROS. In order to imitate the sy...

Cholinesterases are enzymes able to hydrolyze the neurotransmitter acetylcholine and thus to terminate transmission. Once the enzymes are inhibited, excitotoxicity can appear in the adjacent cells. It is well known that oxidative stress is involved in the toxicity of cholinesterase inhibitors. Commonly, stress follows inhibition of cholinesterases and disappears shortly afterwards. In the prese...
