Perinatal hypoxia increases susceptibility to high-altitude polycythemia and attendant pulmonary vascular dysfunction
(Am J Physiol Heart Circ Physiol, 2015-04-27)
Perinatal hypoxia increases susceptibility to high-altitude polycythemia and
attendant pulmonary vascular dysfunction. Am J Physiol Heart Circ
Physiol 309: H565–H573, 2015. First published June 19, 2015;

Sleep-disordered breathing and oxidative stress in preclinical chronic mountain sickness (excessive erythrocytosis)
(Respiratory Physiology & Neurobiology, 2013-01-22)
Abstract.
Chronic mountain sickness (CMS) is considered to be a loss of ventilatory acclimatization to high
altitude (>2500 m) resulting in marked arterial hypoxemia and polycythemia. This case-control
study explores ...
Graduated effects of high-altitude hypoxia and highland ancestry on birth size
(Pediatric Research, 2013-10-02)
Background: We present a cohort of ca. 25,000 birth
records from Bolivia of men and women who are currently
adults. We used this cohort to test the hypothesis that high
altitude reduces birth weight and that highland ...
Potential role for elevated maternal enzymatic antioxidant status in Andean protection against altitude-associated SGA
(The Journal of Maternal-Fetal and Neonatal Medicine, 2012)
Oxidative stress has been implicated in the uteroplacental
ischemia characteristic of preeclampsia and small-for-gestational-age (SGA) birth, both of which are more common at high
(>2500 m) vs low altitude. Since Andeans ...
The relationship between perinatl hypoxia and sleep-disordered breathing in preclinical chronic mountain sickness
(High Altitude Medicine & Biology, 2010-08-08)
Introduction: Chronic intermittent hypoxia due to sleepdisordered breathing is implicated as a potential etiological
factor for chronic mountain sickness (CMS). Whether sleepdisordered breathing precedes or results from ...
Inhibition of peroxisome proliferator gamma (PPARɣ) : a potential link between chronic maternal hypoxia and impaired fetal growth
(Journal of Women's Health, 2013)
Background and Objective: Chronic maternal hypoxia impairs
fetal growth and increases the incidence of intrauterine growth restriction (IUGR). To identify the mechanisms underlying these hypoxia-related effects, we evaluated ...
Do anti-angiogenic or angiogenic factors contribute to the protection of birth weight at high altitude afforded by andean ancestry?
(Reprod Sci., 2010-09)
Abstract.
Objective: This prospective study was designed to determine whether variation in angiogenic
(placental growth factor [PlGF]) and/or anti-angiogenic (soluble fms-like tyrosine kinase [sFlt-1])
factors contribute ...
Perinatal origins of chronic mountain sickness : the role of perinatal hypoxia in the development of CMS
(Meeting VII Congress World Medicine and Physiology High Altitude, 2011)
Andean and Tibetan patterns of adaptation to high altitude
(American Journal of Human Biology, 2013-01-24)
Objectives: High-altitude hypoxia, or decreased oxygen levels caused by low barometric pressure, challenges the
ability of humans to live and reproduce. Despite these challenges, human populations have lived on the Andean ...
High-end arteriolar resistance limits uterine artery blood flow and restricts fetal growth in preeclampsia and gestational hypertension at high altitude
(Am J Physiol Regul Integr Comp Physiol, 2011)
The reduction in
infant birth weight and increased frequency of preeclampsia (PE) in
high-altitude residents have been attributed to greater placental hypoxia, smaller uterine artery (UA) diameter, and lower UA blood ...
