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 ...
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 ...
High-altitude hypoxia and echocardiographic indices of pulmonary hypertension in male and female chickens at adulthood
(Circulation Journal, 2014-06)
Background: By combining the chick embryo model with incubation at high altitude (HA), the effects of chronic hypoxia on fetal growth, fetal cardiac and aortic wall remodeling and systemic arterial blood pressure at adulthood ...

Ancient human genomes suggest three ancestral populations for present-day Europeans
(Nature, 2014-09-18)
We sequenced the genomes of a 7,000-year-old farmer from Germanyandeight 8,000-year-oldhunter-gatherersfromLuxembourg and Sweden. We analysed these and other ancient genomes1–4 with 2,345contemporaryhumanstoshowthatmostp ...
Maternal and fetoplacental hypoxia do not alter circulating angiogenec growth effectors during human pregnancy
(Biol Reprod., 2014-02-27)
Abstract.
One causal model of preeclampsia (PE) postulates that
placental hypoxia alters the production of angiogenic growth
effectors (AGEs), causing an imbalance leading to maternal
endothelial cell dysfunction. We ...
Plasma antioxidant capacity in highland subjects exposed at 5200 meters of altitude
(Revista Boliviana de Química, 2014-06-30)
Abstract.
Human exposure to high altitude conditions (reduced barometric pressure) leads to the formation of free radicals,
which could be a major cause of altitude sickness. In the present study the total antioxidant ...
Climate change and global health : a Latin American perspective
(CAB International, 2014)
Abstract:
The epidemiological profile of Latin America (LA) is marked by diseases of poverty and underdevelopment. Climate change is also reinforcing the intensity and frequency of climate variability, with more intense ...
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 ...
