Pulmonary hypertension in high-altitude dwellers : novel mechanisms, unsuspected predisposing factors
(Adv Exp Med Biol., 2006)
Abstract
Studies of high-altitude populations, and in particular of maladapted subgroups, may provide important insight into underlying mechanisms involved in the pathogenesis of hypoxemia-related disease states in general. ...
Maternal oxygen delivery is not related to altitude- and ancestry-associated differences in human fetal growth
(J Physiol, 2007-09-16)
Fetal growth is reduced at high altitude, but the decrease is less among long-resident populations.
We hypothesized that greater maternal uteroplacental O2 delivery would explain increased
fetal growth in Andean natives ...
Determinants of blood oxygenation during pregnancy in Andean and Europeas residents of high altitude
(Am J Physiol Regul Integr Comp Physiol, 2007-07-02)
High altitude decreases birth weight,
but this effect is diminished in long vs. short-resident, high-altitude
populations. We asked whether women from long vs. short-resident,
high-altitude populations had higher arterial ...
Chronic mountain sickness, optimal hemoglobin and heart disease
(High Altitude Medicine & Biology, 2006-06)
Abstract.
For the male inhabitants of La Paz, Bolivia
(3200–4100 m), and other high altitude regions in America and Asia, chronic mountain sickness
(CMS) is a major health problem. Since CMS was first described by Carlos ...
Valores hematológicos normales en personas sanas a 4.000 metros en Bolivia

Resumen.
Los valores normales hematológicos de salud para las personas que viven a 4,000 m en Bolivia, según el libro
de Biología Médica de altura 2:361-367, 2001 - Es definido que el hematocrito normal y los niveles ...
Commentary on the consensus statement being prepared for the 6th World Congress on Mountain Medicine, Xining 2004
(Journal of Qinghai Medical College, 2005)
In, conclusion, while I agree that it is important to have a valid, cross - cultural scoring system that permits diagnosis of CMS in much the same way as does the Lake Louise system devised for AMS in the 1990s, I do not ...
Dopaminergic metabolism in carotid bodies and high altitude acclimatization in female rats
(Am J Physiol Relulatory, 2002-04)
We tested
the hypothesis that ovarian steroids stimulate breathing
through a dopaminergic mechanism in the carotid bodies (CB). In
ovariectomized female rats raised at sea level, domperidone,
a peripheral D2 receptor ...
Pulmonary nitric oxide in mountain dwellers
(NATURE, 2001-11-22)
Nitric oxide is synthesized in the lungs to help regulate blood flow, and its levels have been found to drop in
species native to low altitudes, including
humans, upon acute exposure to reduced
oxygen concentration1–3. ...
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 ...
Excessive polycythemia occurs in young high-altitude (3600 M) residents in the absence of lung disease
(High Altitude Medicine & Biology, 2002-04-18)
Objective: Chronic Mountain Sickness occurs in , 8% of the La Paz
population. We asked whether its primary diagnostic sign, excessive polycythemia (EP), occurred in youngeraged persons
without lung disease. Methods: ...
