Yolk vitamin E prevents oxidative damage in gull hatchlings
Oxidative stress experienced during early development can negatively affect diverse life-history traits, and organisms have evolved complex defence systems against its detrimental effects. Bird eggs contain maternally derived exogenous antioxidants that play a major role in embryo protection from oxidative damage, including the negative effects on telomere dynamics. In this study on the yellow-...
متن کاملContrasting effects of increased yolk testosterone content on development and oxidative status in gull embryos.
Hormone-mediated maternal effects generate variation in offspring phenotype. In birds, maternal egg testosterone (T) exerts differential effects on offspring traits after hatching, suggesting that mothers experience a trade-off between contrasting T effects. However, there is very little information on T pre-natal effects. In the yellow-legged gull (Larus michahellis), we increased yolk T conce...
متن کاملVitamin C and Oxidative DNA Damage Revisited
Reactive oxygen metabolites can pro mote carcinogenesis by damaging DNA. vi tamin C is a redox chemical with antioxi dant and pro-oxidant properties that may produce radical species depending on the presence of various conditions. Nevertheless, evidence presented herein discourages the consideration of any mutagenic or carcino genic activity of vitamin C. In contrast, it substantiates a pro...
متن کاملCalcium, zinc and vitamin E ameliorate cadmium-induced renal oxidative damage in albino Wistar rats
This study was aimed to examine the protective effects of supplementation with calcium + zinc (Ca + Zn) or vitamin E (Vit-E) on Cd-induced renal oxidative damage. Young albino Wistar rats (180 ± 10 g) (n = 6) control rats, Cd, Cd + Ca + Zn, and Cd + Vit-E experimental groups and the experimental period was 30 days. Rats were exposed to Cd (20 mg/kg body weight) alone treated as Cd treated group...
متن کاملVitamin E Protects against Oxidative Damage Caused by Cadmium in the Blood of Rats
Aim: The protective effect of vitamin E (vit E) on cadmium (Cd) induced oxidative stress was studied in the blood of rats. Methods: The rats were randomly divided in to three experimental groups: Control, Cd treated and Cd + vit E treated, each containing 10 animals. The Cd treated and Cd + vit E treated groups were injected subcutaneously daily with CdCl2 dissolved in isotonic NaCl in the amou...
