  • Maternal oxygen delivery is not related to altitude- and ancestry-associated differences in human fetal growth 

    Zamudio, Stacy; Postigo, Lucrecia; Illsley, Nicholas P; Rodriguez, Carmelo; Heredia, Gladys; Brimacombe, Michael; Echalar, Lourdes; Torricos, Tatiana; Tellez, Wilma; Maldonado, Ivan; Balanza Erquicia, Elfride; Alvarez, Tatiana; Ameller, Julio; Vargas, Enrique (J Physiol, 2007-09-16)
    Fetal growth is reduced at high altitude, but the decrease is less among long-resident populations. We hypothesized that greater maternal uteroplacental O2 delivery would explain increased fetal growth in Andean natives ...
  • Where the O2 goes to : preservation of human fetal oxygen delivery and consumption at high altitude 

    Postigo, Lucrecia; Heredia, Gladys; Illsley, Nicholas P; Torricos, Tatiana; Dolan, Caitlin; Echalar, Lourdes; Tellez, Wilma; Maldonado, Ivan; Brimacombe, Michael; Balanza, Elfride; Vargas, Enrique; Zamudio, Stacy (The Journal of Physiology, 2009)
    Fetal growth is decreased at high altitude (> 2700 m). We hypothesized that variation in fetal O2 delivery might account for both the altitude effect and the relative preservation of fetal growth in multigenerational ...
