(Universidad Mayor de San Andrés, 1990)
Resumen.
Se comunica la primera Hb mutada encontrada en Bolivia “J Bolivia”, siendo esta Hb de migración rápida, estable al isopropanol de mutación en cadena alfa e hiperafín.
Esta variante se halló en un joven de 22 ...
Perinatal hypoxia increases susceptibility to high-altitude polycythemia and attendant pulmonary vascular dysfunction

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 ...
Perinatal origins of chronic mountain sickness : the role of perinatal hypoxia in the development of CMS

Protective effect of female sex hormones against pulmonary hypertension in Bolivian high altitude natives
(High Altitude Medicine & Biology, 2003-02-19)
There is abundant evidence that female sex hormones have protective effects in the systemic circulation in both animals and humans,
but little is known regarding their role in the regulation of the pulmonary circulation. ...
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: ...
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 ...
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 ...
Role of genetic and environmental factors in the increased blood pressures of Bolivian blacks
(American Journal of Human Biology, 1999)
Abstract.
The tendency toward hypertension or higher blood pressure is more common in blacks than whites. The factors that account for these differences are attributed to both environmental and genetic factors. To clarify ...
Greater uterine artery blood flow during pregnancy in multigenerational (Andean) than shorter-term (European) high-altitude residents
(Am J Physiol Regul Integr Comp Physiol, 2007)
Multigenerational (Andean) compared with shorter-term (European) high-altitude
residents exhibit less hypoxia-associated reductions in birth
weight. Because differences in arterial O2 content are not responsible,
we ...
