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 ...
Offspring of preeclamptic mothers are predisposed to hypoxic pulmonary hypertension
(High Altitude Medicine & Biology, 2005-02-22)
Adverse events in utero may predispose to cardiovascular disease in adulthood. In preeclampsia, the diseased placenta releases circulating vasculotoxic factors
that cause maternal endothelial dysfunction. These factors ...
Permormance of altitude acclimatized and non-acclimatized professional football (soccer) players at 3,600 M
(Journal of Exercise Physiology, 2000-04-02)
European football (soccer)
matches frequently are played at the international level in mountainous regions of South America. In this study, the exercise
response during cycle ergometry and the rate of football match ...
Absence of work efficiency differences during cycle ergometry exercise in Bolivian Aymara
(High Altitude Medicine & Biology, 2004)
ABSTRACT.
This study tested the hypothesis that Andean natives are adapted to high altitude (HA) via high work ef
ficiency during exercise in hypoxia. A total of 186 young males and females were tested in Bo
livia, ...
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 ...
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 ...
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 ...
