The scientific evaluation of medicinal plants used in the preparation of folk remedies has provided modern medicine with effective pharmaceuticals for the treatment of diseases. The methanol extract of Berberis tinctoria Lesch (Berberidaceae) leaves was investigated for its hepatoprotective and antioxidant effects on paracetamol (750 mg/kg) induced acute liver damage in Wistar albino rats. Hepa...

This study aimed to evaluate, in vitro, the antioxidative potential of fruit wines produced from berry fruits (i.e., black chokeberry, blueberry, blackberry, and raspberry), cherry, apple by different technological processes. For this purpose, activities antioxidant enzymes (catalase, glutathione peroxidase (GPx), superoxide dismutase (SOD)) malondialdehyde (MDA) content as a marker membrane da...

Reactive oxygen species (ROS) play essential roles in cell signaling, survival, and homeostasis. Aberrant ROS lead to disease and contribute to the aging process. Numerous enzymes and vigilant antioxidant pathways are required to regulate ROS for normal cellular health. Mitochondria are a major source of ROS, and mechanisms to prevent elevated ROS during oxidative phosphorylation require super ...

OBJECTIVE To measure the lipid peroxidation and endogenous antioxidant enzyme status in oral carcinoma and the protective role of exogenous antioxidants. MATERIAL AND METHODS 20 new cases of histologically proven oral squamous cell carcinoma, 20 of leukoplakia and 20 age and sex matched healthy conrols were included. Intra oral pH of patients and controlled were measured by quantitative litmu...

Superoxide dismutase (SOD) isoenzymes of the rumen bacterium Streptococcus bovis 4/1 were studied. Native PAGE showed a single band of Mn-SOD, unaffected by 10 mM cyanide or 5 mM hydrogen peroxide under both aerobic and anaerobic growth conditions. When the metals were removed from the growth medium by Chelex 100, the addition of manganese increased enzymatic activity, while addition of iron in...

Various effects of exposure to volatile organic compounds (VOC) have recently become an important issue because of their widespread use in industry. The aim of this study was to determine the effect of volatile organic solvents commonly used in textile paint industry on free radical levels and the antioxidant enzyme system in textile workers. The study included twenty exposed workers and twenty...

Concentration of engineered nickel oxide nanoparticle (NiO-NP) in nature is on the rise, owing to large scale industrial uses, which have accreted the scope of its exposure to plants, the primary producers of the ecosystem. Though an essential micronutrient for the animal system, supported by numerous studies confirming its toxicity at higher dosages, nickel oxide is graded as a human carcinoge...

the effect of salinity was assessed on the activity of some major antioxidant enzymes i.e., superoxide dismutase (sod), peroxidase (pod), catalase (cat), in the seedlings’ roots or shoots of three winter canola (brassica napus l.) cultivars, colvert (tolerant), symbol (semi tolerant) and agat (susceptible). seedlings were treated with 0 (control), 50, 100 and 150 mm nacl for 24 h in hydropoic c...

Periplasmic Cu, Zn-cofactored superoxide dismutase (SodC) protects Gram-negative bacteria from exogenous oxidative damage. The virulent Salmonella typhimurium strain ATCC 14028s has been found to contain two discrete periplasmic Cu, Zn-SOD enzymes that are only 57% identical at the amino acid level. SodCI is carried by a cryptic bacteriophage, and SodCII is closely related to the Cu, Zn-superox...

To evaluate the efficacy of biochelators for phytoremediation cadmium (Cd), effects (humic acid, HA; polyaspartic PASP; rhamnolipid, RLs) and synthetic chelator (sodium tripolyphosphate, STPP) on growth, accumulation, antioxidant index Cd were investigated in Iris sibirica L. The results indicated that addition HA increased dry weight leaves stems, PASP, RLs, STPP growth but inhibited stems. de...
