Pulmonary gas exchange and acid-base state at 5,260 m in high-altitude Bolivians and acclimatized lowlanders
(J Appl Physiol, 2002)
Pulmonary gas exchange and acid-base state were compared
in nine Danish lowlanders (L) acclimatized to 5,260 m for 9
wk and seven native Bolivian residents (N) of La Paz (altitude 3,600–4,100 m) brought acutely to this ...
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, ...
Seasonal modulation of reproductive effort during early pregnancy in humans
(American Journal of Human Biology, 2009-03-03)
Abstract.
Life history theory predicts that early pregnancy presents a relatively low cost, uncontested opportunity for a woman to terminate investment in a current reproductive opportunity if a conceptus is of poor quality ...

Change in body water distribution index in infants who become stunted between 4 and 18 months of age
(European Journal of Clinical Nutrition, 2003-08)
Objective.
To evaluate body composition changes using bioelectrical impedance analysis and skinfold thickness measurements in infants from tropical areas who become stunted between 4–18 months of age.
Design and measurements: ...
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 ...
A prospective study of early pregnancy loss in humans
(Fertility and Sterility, 2006-08)
Objective: To test two hypotheses: In spontaneous conceptions, early pregnancy loss (EPL) is associated with [1]
inadequate luteal (ovarian) P, and/or [2] elevated follicular (adrenal) P.
Design: A population-based ...
Salivary progesterone levels and rate of ovulation are significantly lower in poorer than in better-of urban-dwelling Bolivian women
(Human Reproduction, 2002)
Agriculturalists in less-developed countries (LDC) have lower progesterone levels than urban industrialized populations. However, it is unknown if urban LDC populations are also relatively lower. We tested whether urban ...
Patrones reproductivos en la altura : hipoxia o regulación cultural

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 ...
