the aim of this study was to analyze the incidence of stage of embryonic development, embryo quality and the time of transfer on pregnancy rate in embryo transfer program timed. we were worked a total of 23holsteincowsasembryo donors, super-ovulated with gonadotropin of pregnant mare serum (pmsg) (2500 3000ui).69 cows were used as recipients of holstein dairy heifers with an age of20 months and...

Background: Strenuous acute exercise induces oxidative stress in the active muscles and circulation, However, consumption of products rich in antioxidants may potentially ameliorate these effects. Objective: The present investigation was conducted to determine the effect of Artichoke (Cynara scolymus L.) extract on oxidative stress and antioxidant defense after aerobic exercise in young athle...

OBJECTIVE Type 1 diabetes is associated with increased platelet reactivity. We investigated whether α-lipoic acid (ALA) has any effect on platelet reactivity in these patients. RESEARCH DESIGN AND METHODS We randomly assigned 51 type 1 diabetic patients to ALA (600 mg once daily) or placebo for 5 weeks. Platelet reactivity was evaluated by the PFA-100 method and by measuring CD41 and CD62 pla...

Background: The immaturity of glutathione metabolism is believed to explain the oxidative stress observed in premature neonates on total parenteral nutrition [TPN]. Animal studies report that peroxides contaminating TPN induce the low glutathione levels as a consequence of the inhibition of the generation of substrates for its synthesis. We hypothesize that older children receiving long-term TP...
