Andean women have greater uterine artery (UTA) enlargement during pregnancy than european residents of 3600 m.
(s.n., 2003)Abstract. Babies weigh less at high altitude but multi-generational high-altitude residents are protected from this birth weight decline (Moore HAMB 2001). Objective: We asked if higher arterial oxygenation and/or blood ... -
Do cytokines contribute to the andean-associated protection from reduced fetal growth at high altitude?
(Reproductive Sciences, 2011)Abstract Pro- versus anti-inflammatory cytokine balance is important for successful pregnancy. Chronic hypoxia alters cytokine levels and increases the frequency of fetal growth restriction (FGR). Multigenerational Andean ... -
Higher estrogen levels during pregnancy in Andean than European residents of high altitude suggest differences in aromatase activity
(J Clin Endocrinol Metab, 2014-08)Context: Uteroplacental hypoxia has been reported to lower estrogen levels in preeclampsia as the result of reduced aromatase activity. Objective: We asked whether the chronic hypoxia of residence at high altitude in the ... -
Lowland origin women raised at high altitude are not protected against lower uteroplacental O2 delivery during pregnancy or reduced birth weight
(American Journal of Human Biology, 2011-04-27)Objective. Maternal physiologic responses to pregnancy promoting fetal oxygen and nutrient delivery are important determinants of reproductive success. Incomplete physiologic compensation for reduced oxygen availability ... -
Maternal adaptation to high-altitude pregnancy : an experiment of nature-a review
(Placenta, 2004)A long and productive history of studies at high altitude has demonstrated that chronic hypoxia plays a key role in the aetiology of intrauterine growth restriction (IUGR) and pre-eclampsia. Susceptibility to altitude-associated ... -
Maternal and fetoplacental hypoxia do not alter circulating angiogenic growth factors: the emperor's got no clothes?
(The Journal of Clinical Endocrinology & Metabolism, 2010)ABSTRACT Context: Placental hypoxia alters production of angiogenic growth factors (AGFs), thought to be causally involved in the development of the pregnancy-specific disease preeclampsia (PE). Consistent with this, ... -
Reduced endothelin-1 (ET-1) and elevated nitric oxide metabolites (NOX) across pregnancy among andean vs. european women at high (3100-3600 m) altitude
(High Altitude Medicine & Biology, 2005-02-22)Background: A consistent reduction in infant birth weight occurs with ascending altitude; however multigenerational high-altitude residents [Andeans] demonstrate a degree of protection from altitude-associated IUGR ... -
Uterine artery blood flow during pregnancy in high-altitude aymara women
(High Altitude Medicine & Biology, 2003-02-19)Background: Birth weight falls with increasing altitude as the result of intrauterine growth restriction (IUGR) likely due, in turn, to lower uterine artery (UtA) blood flow. The altitude-associated birth weight decline is ...
