We investigated the protective role of exogenous nitric oxide (NO) in alleviating high temperature induced damages of wheat (Triticum aestivum L. cv. Pradip) seedlings. Heat treatment (38 °C) alone or in combination with 0.5 mM SNP (a NO donor) was applied with nutrient solution on 8-d-old hydroponically grown seedlings for a period of 24 h and 48 h. Heat stress significantly decreased the Chl ...

We evaluated the preventive effects of Terminalia chebula (T. chebula) aqueous extract on oxidative and antioxidative status in liver and kidney of aged rats compared to young albino rats. The concentrations of malondialdehyde (MDA), lipofuscin (LF), protein carbonyls (PCO), activities of xantione oxidase (XO), manganese-superoxide dismutase (MnSOD), catalase (CAT), glutathione peroxidase (GPx)...

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...

Abstract Metals and agrochemicals are among the main aquatic contaminants, being able to trigger oxidative stress in exposed organisms. The objective of this work was evaluate correlation between level biomarkers Aegla crabs (Crustacea, Anomura) with (i) set metals present streams sediment (ii) land uses three hydrographic basins. study carried out (≤ 2nd order) basins southern Brazil (Basins R...

The antioxidant effect of aqueous-ethanolic extract from Astragalus glycyphylloides (Fabaceae), and its protection against carbon tetrachloride-induced hepatotoxicity were investigated in male Wistar rats. For seven consequent days the animals were treated orally with A. glycyphylloides extract (EAG) (100 mg/kg). Two hours after the last administration the animals were charged with carbon tetra...

Carbon tetrachloride (CCl4), a hepatotoxic agent is widely used to study the toxic mechanisms in experimental animals. We have investigated whether oxidative stress is induced in the brain at a single hepatotoxic dosage (1 ml/kg bw) of CCl4. Increased lipid peroxidation (LPO), protein carbonyls (PC) content and glutathione (GSH) depletion were observed in the brain regions of rats treated with ...

We investigated the effects of Hericium erinaceus (HEE) on alloxan induced diabetic neuropathic pain in laboratory rats. Alloxan induced diabetic rats were administered orally HEE. After 6 weeks of treatments, treatment with HEE 40 mg/kg in diabetic animals showed significant increase in pain threshold and paw withdrawal threshold and significant decrease in serum glucose and urine glucose. We ...

thioredoxins (trxs) are small ubiquitous oxidoreductase proteins with two redox-active cys residues in a conserved active site (wcg/ppc) that regulate numerous target proteins via thiol/disulfide exchanges in the cells of prokaryotes and eukaryotes. the isoforms ostrx23 with a typical active site (wcgpc) and ostrx20 with an atypical active site (wctpc) are two  trx h- type isoforms in rice that ...

The mechanism by which glutathione reductase (GR) activity is regulated in relation to fiavin metabolism was studied in red cells of normal adults, cord blood, and patients with severe metabolic disorders using spectrophotometnc, fluorometnc, and radiochemical methods. The increased activity of GR in red cells of adult patients with severe hepatic cirrhosis, chronic uremia, and glucose-6-phosph...

GENOPLANTE programme " Redoxome ". Financial support of postgraduate students from the following sources is gratefully acknowledged: the Tunisian Ministry of Higher Education Abstract Glutathione is a major cellular thiol that is maintained in the reduced state by glutathione reductases (GR), which is encoded by two genes in Arabidopsis thaliana (GR1 and GR2). This study addressed the role of G...
