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 ...
Comparative aspects of high-altitude adaptation in human populations
(Adv. Exp. Med. Biol., 2000)
Abstract.
The conditions and duration of high-altitude residence differ among high-altitude populations. The Tibetan Plateau is larger, more geographically remote, and appears to have been occupied for a longer period of ...
Excessive polycythemia occurs in young high-altitude (3600 m) residents in the absence o lung disease
(Health & height proceeding, 2002)
Summary.
Chronic mountain sickness is present in about 8% of the male population of La Paz. Our question was whether its principal diagnostic sign, excessive polycythemia (EP) without lung disease could be found already ...
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 ...
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 ...
Efectos del tabaquismo en una población de altura (La Paz- Bolivia 3600 m.)
(Revista Boliviana de Nefrología, 1990)
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 ...
Andean compared with european women are protected from altitude-associated intrauterine growth restriction (IUGR)
(s.n., 2003)
Abstract.
Babies born at high altitude to long-term high-altitude residents weigh more than those of recent migrants from low altitude. Objective: We asked whether a gradient exists such that persons of Andean ancestry ...
