Helping patterns and reproductive success in Aymara communities
(American Journal of Human Biology, 2002)
Abstract.
“Helpers at the nest,” young adults remaining in their parents home to take care of younger siblings, are known in many species of birds and mammals. Similar behaviors are occasionally observed in human societies ...
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 ...

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 ...
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 ...
Effect of high altitude on protein metabolism in Bolivian children
(High Altitude Medicine & Biology, 2002-08-01)
Abstract.
In Bolivia, malnutrition in children is a major health problem that may be caused by inadequate protein, energy, and micronutrient intake; exposure to bacterial and parasitic infections; and ...
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 ...
Effect of menstrual cycle phase on exercise performance of high-altitude native women at 3600 m
(The Journal of Experimental Biology, 2002)
Summary.
At sea level normally menstruating women show
increased ventilation (VE) and hemodynamic changes due
to increased progesterone (P) and estrogen (E2) levels
during the mid-luteal (L) compared to the mid-follicular
(F) ...
