this study was conducted to determine the effect of dietary turmeric rhizome powder (trp) as a natural antioxidant, and soybean oil, canola oil and tallow on lipid metabolism, blood metabolites, immune system, and antioxidant status of broiler chickens before (bhs, 28 d) and after exposure to heat stress (ahs, 42 d). seven hundred and ninety two d-old male arian broilers were randomly allotted ...

Three different experiments were conducted to study the effect of dietary astaxanthin on the immune response, resistance to white spot syndrome virus (WSSV) and transcription of antioxidant enzyme genes in Pacific white shrimp Litopenaeus vannamei. Each experiment included one triplicate treatment group (fed with 80 mg/kg astaxanthin supplemented diet) and one triplicate control group (fed with...

This study was performed to investigate the effect of Ag+ as an elicitor on the activity of antioxidant enzymes, content of H2O2, accumulation of total tocopherol and antioxidant activity in hairy root cultures of Silybum marianum (L.) Gaertn. The hairy roots were treated with 2 mM Ag+. The treated and non-treated hairy roots were harvested in the same time and data on H2O2 content, DPPH, tocop...

Substantial evidence supports a key role for reactive oxygen species (ROS) in causing cumulative damage to cellular macromolecules, thereby contributing to senescence. Antioxidants can scavenge ROS while protein turnover removes and replaces oxidized proteins. How these defence systems vary with age and with metabolic demand is not well known. In the present study 2H5-phenylalanine was injected...
