Lowland origin women raised at high altitude are not protected against lower uteroplacental O2 delivery during pregnancy or reduced birth weight
(American Journal of Human Biology, 2011-04-27)Objective. Maternal physiologic responses to pregnancy promoting fetal oxygen and nutrient delivery are important determinants of reproductive success. Incomplete physiologic compensation for reduced oxygen availability ... -
La maladie de Chagas en Bolivie : données préliminaires sur les cycles domestiques : méthodes simplifiées de capture des triatomes
(Ent. Med. et Parasitol, 1984)Résumé. Nous présentons ici des résultats portant sur l'examen de 1664 spécimens de Triatoma infestans récoltés en Bolivie dans des gîtes domestiques. Le taux global d'infection, était de 42 %, et les maisons ne contenant ... -

Maternal adaptation to high-altitude pregnancy : an experiment of nature-a review
(Placenta, 2004)A long and productive history of studies at high altitude has demonstrated that chronic hypoxia plays a key role in the aetiology of intrauterine growth restriction (IUGR) and pre-eclampsia. Susceptibility to altitude-associated ... -
Maternal and fetoplacental hypoxia do not alter circulating angiogenec growth effectors during human pregnancy
(Biol Reprod., 2014-02-27)Abstract. One causal model of preeclampsia (PE) postulates that placental hypoxia alters the production of angiogenic growth effectors (AGEs), causing an imbalance leading to maternal endothelial cell dysfunction. We ... -
Maternal and fetoplacental hypoxia do not alter circulating angiogenic growth factors : the emperor's got no clothes?
(The Journal of Clinical Endocrinology & Metabolism, 2010)ABSTRACT. Context: Placental hypoxia alters production of angiogenic growth factors (AGFs), thought to be causally involved in the development of the pregnancy-specific disease preeclampsia (PE). Consistent with this, ... -
Maternal oxygen delivery is not related to altitude- and ancestry-associated differences in human fetal growth
(J Physiol, 2007-09-16)Fetal growth is reduced at high altitude, but the decrease is less among long-resident populations. We hypothesized that greater maternal uteroplacental O2 delivery would explain increased fetal growth in Andean natives ... -
Maternal PRKAA1 and EDNRA genotypes are associated with birth weight, and PRKAA1 with uterine artery diameter and metabolic homeostasis at high altitude
(Physiol Genomics, 2014-07-14)Low birth weight and intrauterine growth restriction (IUGR) increase the risk of mortality and morbidity during the perinatal period as well as in adulthood. Environmental and genetic factors contribute to IUGR, but the ... -
Matrix remodelling and fibroblast phenotype in early lesions of human cutaneous Leishmaniasis
(Path. Res. Pract., 1991)SUMMARY. The connective matrix participates directly in early pathological events observed in the cutaneous lesion of leishmaniasis, due to Leishmania braziliensis guyanensis. A sample of 19 skin biopsies was examined ... -
Maximal aerobic power in high-altitude runners
(Annals of Human Biology, 1993)Abstract. Maximal aerobic power (VO2max) was assessed in seven male and one female middle- and long-distance recreational runners residing in La Paz, Bolivia (3600 m). All runners were born and raised at high altitudes ... -
Maximal exercise capacity in adolescent european and amerindian high-altitude natives
(American Journal of Physical Anthropology, 1985)ABSTRACT Forty-seven highland natives were given maximal exercise tests on a treadmill ergometer at 3,600 m. The subjects were grouped into four subsamples on the basis of ethnicity (European vs. Aymara) and age (young ... -
Maximal exercise performance in chronic hypoxia and acute normoxia in high-altitude natives
(J. Appl. Physiol., 1995)Maximal O₂ uptake (VO₂max) was determined on a bicycle ergometer in chronic hipoxia (CH) and during acute exposure to normoxia (AN) in 50 healthy Young men who were born and had lived at 3,600 m altitude (La Paz, Bolivia). ... -
Mecánica ventilatoria en el hombre habitante de altura
(Instituto Boliviano de Biología de Altura, 1979)Las propiedades mecánicas toracopulmonares son idénticas al nivel de mar y a grandes alturas, cualquiera que sea el lugar de nacimiento de los sujetos. La única modificación observada en los dos grupos de sujetos es un ... -
Mecánica ventilatoria en pacientes con eritrocitosis de altura
(Instituto Boliviano de Biología de Altura, 1979)Se trata de un análisis de los aspectos generales que intervienen en la mecánica ventilatoria así como los factores que determinan sus variaciones patológicas. Fueron estudiados 138 pacientes poliglobúlicos de los cuales ... -

Medición del contenido de oxígeno en la sangre con un electrodo Po₂
(Instituto Boliviano de Biología de Altura, 1972-10)El método descrito fue modificado especialmente para ser usado en conección con una investigación del flujo sanguíneo cerebral y del metabolismo anaeróbico en La Paz, en el Instituto Boliviano de Biología de la Altura ... -

El metabolismo anaeróbico durante la pubertad en la altura
(Universidad Mayor de San Andrés, 1990)Resumen. En un estudio anterior hemos mostrado que no existían diferencias en el metabolismo anaeróbico entre grupos de niños de 11 años que vivían en la altura (3,700 m.) y en tierras bajas (330 m). El propósito del ...
