(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 ...
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 ...
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, ...
New data demonstrates that relationship of salivary to serum progesterone in Bolivian women is comparable to that in other populations
(36th Annual Meeting Minnesota, 2011-04-13)
Abstract.
Salivary progesterone (P) concentration is widely
used in field studies as a relatively easy-to-measure
proxy for serum P. Chatterton et al. [Fertility & Sterility 86:723 (2006)] compared sample means of ...
Sixty percent (60%) mean hematocrit in an andean human population permanently exposed to extreme life conditions

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

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 ...
Epidemiological transitions, reproductive health, and the Flexible Response Model
(ECONOMICS AND HUMAN BIOLOGY, 2003)
Abstract.
In concert with improving standards of living since the mid-19th century, chronic and non-infectious diseases replaced infectious diseases as the major causes of mortality in more developed countries. Thus, ...

Exaggerated pulmonary hypertension during mild exercise in chronic mountain sickness
(CHEST, 2010-02)
Background: Chronic mountain sickness (CMS) is an important public health problem and is characterized by exaggerated hypoxemia, erythrocytosis, and pulmonary hypertension. While pulmonary hypertension is a leading cause ...
