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 ...
Role of cytokines in altitude-associated preeclampsia
(Pregnancy Hypertens, 2012-01)
Abstract.
Background: Preeclampsia (PE) is more common at high than low altitude and contributes
to the altitude-related decline in birth weight. Since inflammatory markers are implicated
in PE, we asked if such markers ...
Inhibition of peroxisome proliferator-activated receptor ɣ : a potential link between chronic maternal hypoxia and impaired fetal growth
(FASEB Journal, 2014)
Abstract.
Chronic exposure to hypoxia raises the
risk of pregnancy disorders characterized by maternal
vascular dysfunction and diminished fetal growth. In an
effort to identify novel pathways for these hypoxiarelated ...
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 ...
Unique DNA methylation patterns in offspring of hypertensive pregnancy
(Clin Transl Sci., 2015)
Abstract.
Epigenomic processes are believed to play a pivotal role for the effect of environmental exposures in early life to modify disease risk throughout the lifespan. Offspring of women with hypertensive complications ...
Augmented uterine artery blood flow and oxygen delivery protect andeans from altitude-associated reductions in fetal growth
(Am J Physiol Regul Integr Comp Physiol, 2009-02-20)
Abstract.
The effect of high altitude on reducing birth weight is markedly less in
populations of high- (e.g., Andeans) relative to low-altitude origin
(e.g., Europeans). Uterine artery (UA) blood flow is greater ...
Patrones reproductivos en la altura : hipoxia o regulación cultural
(Rev. Arg. Antrop. Biol., 2001)
Maternal PRKAA1 and EDNRA genotypes are associated with birth weight, and PRKAA1 with uterine artery diameter and metabolic homeostasis at high altitude
(Physiol Genomics, 2014-07-14)
Low birth weight and intrauterine growth restriction (IUGR) increase the risk of mortality and
morbidity during the perinatal period as well as in adulthood. Environmental and genetic factors contribute to IUGR, but the ...
Where the O2 goes to : preservation of human fetal oxygen delivery and consumption at high altitude
(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 ...
Intrauterine growth restriction, preeclampsia, and intrauterine mortality at high altitude in Bolivia
(PEDIATRIC RESEARCH, 2003-02-18)
Abstract.
Infant mortality and stillbirth rates in Bolivia are high and birth weights are low compared with other South American countries. Most Bolivians live at altitudes of 2500 m or higher. We sought to determine the ...
