(Cuadernos del Hospital de Clínicas, 2005)
Resumen.
Pregunta de investigación
¿Cuáles son los factores que determinan que los alumnos que cursan el capítulo de Neumología, no pueden describir adecuadamente una placa radiográfica normal de tórax, pese haber cursado ...
Importancia del cálculo de la diferencia alvéolo-arterial de oxígeno en enfermedad pulmonar obstructiva crónica (EPOC) en la altura
(Revista Médica. Órgano Oficial del Colegio Médico de La Paz, 2003)
RESUMEN.
Es un trabajo descriptivo realizado en el lnstituto Boliviano de Biología de Altura, en la ciudad de La Paz, que aplica el cálculo del gradiente alveoloarterial de oxígeno (P(A-a) 02), en la altura, para valorar ...
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 ...
High-altitude ancestry protects against IUGR and reductions in birth weight associated with high altitude and preeclampsia
(High Altitude Medicine & Biology, 2005-02-22)
Background.
Observations consistently demonstrate diminished birth weight [BW] with ascending altitude;
however population comparisons reveal the extent of BW
reduction depends, in part, upon high-altitude ancestry.

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. ...
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, ...
Interpopulational differences in progesterone levels during conception and implantation in humans
(PNAS, 2004-02-10)
Clinical studies of women from the United States demonstrate a
sensitivity of the ovarian system to energetic stress. Even moder
ate exercise or caloric restriction can lead to lower progesterone
levels and failure to ...
European genetic admixture predicts decrement in aerobic performance at 4338 meters in peruvian quechua
(High Altitude Medicine & Biology, 2003-02-19)
Quechua natives of the highland Andes may be genetically
adapted to high altitude and thus able to resist decrements in maximal O2 consumption in hypoxia (DVO2max). This evolutionary hypothesis was tested via the repeated ...

Resumen.
Los partidos del Fútbol Europeo son frecuentemente jugados a nivel internacional en regiones montañosas de Sudamérica. En este estudio, fueron medidas las respuestas del ejercicio durante una ergometría en ciclo ...
Chronic mountain sickness and cor pulmonale La Paz-Bolivia (3,600-4,100 m)
(Life on the Qinghai Tibetan plateau, 2007)
Summary.
Among the majority of inhabitants of La Paz-Bolivia (3,200-4,100 m.), the mild elevation seen in pulmonary artery pressure (PAP) has no clinical significance and is reversible on descent to lower altitude or with ...
