    • Disturbances in Maternal Steroidogenesis and Appearance of Intrauterine Growth Retardation at High-Altitude ... 
      Parraguez Gamboa, Víctor; Mamani, Sandra; Cofre, Eileen; Castellaro, Giorgio; Urquieta Mangiola, Bessie; Reyes Solovera, Mónica de los; Astiz, Susana; González Bulnes, Antonio (Public Library of Science, 2015)
      Pregnancies at high-altitudes are influenced by hypoxia and oxidative stress and frequently affected by IUGR. However, a common thought is that early pregnant women visiting altitude have no major complications for gestation ...
    • Fertility in a high-altitude environment is compromised by luteal dysfunction: the relative roles of hypoxia ... 
      Parraguez Gamboa, Víctor; Urquieta, Bessie; Pérez, Laura; Castellaro Galdames, Giorgio; Reyes Solovera, Mónica de los; Torres Rovira, Laura; Aguado Martínez, Adriana; Astiz, Susana; González Bulnes, Antonio (BioMed Central, 2013-03-23)
      At high altitudes, hypoxia, oxidative stress or both compromise sheep fertility. In the present work, we tested the relative effect of short- or long-term exposure to high altitude hypobaric hypoxia and oxidative stress on ...
    • Maternal supplementation with antioxidant vitamins in sheep results in increased transfer to the fetus and ... 
      Sales, Francisco; Peralta, Oscar A.; Narbona, Eileen; McCoard, Sue; Lira, Raúl; Reyes Solovera, Mónica de los; González Bulnes, Antonio; Parraguez Gamboa, Víctor (MDPI, 2019)
      Twinning and maternal nutritional restriction leads to fetal hypoxia, oxidative stress, and intrauterine growth restriction (IUGR) in near-term sheep pregnancies. Our aim was to determine the effect of oral supplementation ...
    • Maternal supplementation with herbal antioxidants during pregnancy in swine 
      Parraguez Gamboa, Víctor; Sales Zlatar, Francisco Andrés; Peralta Troncoso, Óscar Alejandro; Reyes Solovera, Mónica Isabel de los; Campos, Alfonso; González, Javier; Peralta, Wolfgang; Cabezón, Camila; González Bulnes, Antonio (MDPI, 2021)
      The effects of a combined supplementation with herbal antioxidants during pregnancy on reproductive traits and piglet performance (number of live, dead, and mummified newborns and litter weight at birth and individual ...
    • Rapid Communication: Maternal melatonin implants improve fetal oxygen supply and body weight at term in ... 
      Sales, Francisco; Peralta, Oscar A.; Narbona, Eileen; Mccoard, Sue; González Bulnes, Antonio; Parraguez Gamboa, Víctor (Oxford University Press, 2019)
      Fetal hypoxia, resulting in oxidative stress in pregnancies, contributes to reduced fetal growth. Melatonin, a potent antioxidant, has been associated with improved oxidative status. Maternal oral melatonin supplementation ...
    • Steroidogenesis in sheep pregnancy with intrauterine growth retardation by high-altitude hypoxia: effects ... 
      Parraguez Gamboa, Víctor; Urquieta Mangiola, Bessie; Reyes, Mónica de los; González Bulnes, Antonio; Astiz, Susana; Mansilla Muñoz, Andrés (CSIRO, 2013)
      Sheep pregnancy in high-altitude environments frequently involves hypoxia and oxidative stress and causes intrauterine growth retardation. The adverse effects of altitude on fetal growth can be prevented by the administration ...
