Seasonal and circadian variation in salivary testosterone in rural Bolivian men
(American Journal of Human Biology, 2009-02-19)
Abstract.
Testosterone (T) plays a key role in the increase and maintenance of muscle mass and bone density in
adult men. Life history theory predicts that environmental stress may prompt a reallocation of such investments ...
Evidence that parent-of-origin affects birth-weight reductions at high altitude
(American Journal of Human Biology, 2008-02-19)
Abstract.
Hypoxia exerts a profound depressant effect on fetal growth, lowering birth weight, and raising mortality risk. Multigenerational high-altitude populations are relatively protected from this birth-weight decline, ...

RESUMEN.
La Enfermedad Pulmonar Obstructiva Crónica
(EPOC) es definida como una enfermedad
inflamatoria crónica caracterizada por limitación del
flujo aéreo que no es completamente reversible.
El principal factor de ...
Pulmonary-artery pressure and exhaled nitric oxide in Bolivian and caucasian high altitude dwellers
(High Altitude Medicine & Biology, 2008)
Abstract.
There is evidence
that high altitude populations may be better protected from hypoxic pulmonary hypertension than low altitude natives, but the underlying mechanism is incompletely understood. In Tibetans, ...
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. ...
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: ...
Postnatal changes in the pulmonary circulation at 3700-4000 m
(High Altitude Medicine & Hygiene, 2002-04-18)
Objective: The hypoxia of high altitude can impair
postnatal changes in the pulmonary circulation. We documented pulmonary artery pressures (PPA) and persistence of fetal circulatory patterns among infants born at
3700–4000m ...
Reduced endothelin-1 (ET-1) and elevated nitric oxide metabolites (NOX) across pregnancy among andean vs. european women at high (3100-3600 m) altitude
(High Altitude Medicine & Biology, 2005-02-22)
Background.
A consistent reduction in infant birth
weight occurs with ascending altitude; however multigenerational high-altitude residents [Andeans] demonstrate a degree of protection from altitude-associated
IUGR ...
