Parraguez Gamboa, Víctor; Atlagich, Miljenko; Araneda, Oscar; García, Carlos; Muñoz, Andrés; Reyes Solovera, Mónica de los; Urquieta, Bessie (CSIRO PUBLISHING, 2011)The present study evaluated the hypothesis that the effects of hypoxia on sheep pregnancies at high altitude (HA) are mediated by oxidative stress and that antioxidant vitamins may prevent these effects. Both HA native and ...
