In this research the effect of salicylic acid (SA), acetylsalicylic acid (ASA), and methylsalicylate (MeSA) treatments, applied as a foliar spray during on-tree plum development, on fruit quality attributes, bioactive compounds, antioxidant activity, and the activity of the antioxidant enzymes at harvest and after long-term cold storage was evaluated in two plum cultivars ("Black Splendor", BS,...

PURPOSE The aim of this study was to investigate if common functional antioxidant polymorphisms are associated with epilepsy after neonatal hypoxic-ischemic encephalopathy (HIE). The antioxidant enzymes manganese superoxide dismutase (SOD2), glutathione peroxidase 1 (GPX1) and catalase (CAT) represent the primary defence mechanism against reactive oxygen species (ROS). Evidence suggests that ge...

In freshwater environments direct biological effect of ultraviolet radiation (UVR) result from absorption of specific wavelengths by macromolecules and alteration of biochemical processes. Indirect effects are related to UVR interaction with water and dissolved organic carbon to form chemically reactive species (ROS: reactive oxygen species). Zooplankton photoprotection includes mycosporine-lik...

The present study was designed to investigate the immunomodulatory activity of the ethanolic extract of Tinospora cordifolia (Family: Menispermaceae)stem (climbing shrub, mango plant) at cellular level. For antioxidant study, the liver mitochondria were separated and the concentration of enzymes like lipid peroxidation (LPO), reduced glutathione (GSH), catalase (CAT) and superoxide Dismutase (S...

background: the aim of this study was to evaluate the possible protective effect of sodium selenite on serum, liver, and kidney antioxidant enzymes activities in alloxan-induced type 1 diabetic rats. methods: forty sprague-dawley male rats were randomly divided into four groups; group one as control, group two as sham-treated with sodium selenite by 1 mg/kg intraperitoneal (i.p.) injections dai...

Objective: The aim of this study was to evaluate the effects of pulmonary rehabilitation on oxidative stress biomarker (Thiobarbituric acid substances “TBARS”) and antioxidant enzymes activities (superoxide dismutase “SOD”, glutathione peroxidise “GPx” and catalase “CAT”) in patients with chronic obstructive pulmonary disease (COPD) compared to healthy subjects. Material and Methods: The study ...

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...

Oxyradicals are chemical species with an unpaired electron in one of their orbits. Production of oxyradicals occurs throughout the body during cellular metabolism [l]. A complex antioxidant system exists to regulate levels of oxyradicals as excessive production or ineffective removal can result in cellular damage. The antioxidant enzymes present indude superoxide dismutase (SOD), glutathione pg...

Boerhaavia diffusa (Nyctaginaceae) is conventionally used in Indian Ayurvedic system to treat liver diseases. The present study was undertaken to investigate the protective role of ethanol extract of B. diffusa on hepatic antioxidant status and the levels of diagnostic markers in isoproterenol induced hepatitis in rats. The Prior oral administration of B. diffusa extract [150 mg/kg bodyweight/d...

The effects of Cassia alata aqueous leaves extract, a traditional medicinal herb, was assessed in the liver and renal microsomal of streptozotocin (STZ) induced hyperglycemic rats. In diabetes, hyperglycemia increases the production of free radicals and simultaneously weakens the antioxidant defense mechanism. This leads to the damages on cellular organelles and enzymes, increasing lipid peroxi...
