High-end arteriolar resistance limits uterine artery blood flow and restricts fetal growth in preeclampsia and gestational hypertension at high altitude
(Am J Physiol Regul Integr Comp Physiol, 2011)The reduction in infant birth weight and increased frequency of preeclampsia (PE) in high-altitude residents have been attributed to greater placental hypoxia, smaller uterine artery (UA) diameter, and lower UA blood ... -
Higher arterial oxygen saturation during submaximal exercise in bolivian aymara compared to european sojourners and europeans born and raised at high altitude
(American Journal of Physical Anthropology, 2000)Abstract. Arterial oxygen saturation (SaO(2)) was measured at 3,600-3,850 m by pulse oximetry at rest and during submaximal exercise in three study groups: 1) highland Aymara natives of the Bolivian altiplano (n = 25); ... -
Higher estrogen levels during pregnancy in Andean than European residents of high altitude suggest differences in aromatase activity
(J Clin Endocrinol Metab, 2014-08)Context: Uteroplacental hypoxia has been reported to lower estrogen levels in preeclampsia as the result of reduced aromatase activity. Objective: We asked whether the chronic hypoxia of residence at high altitude in the ... -
Hipertensión arterial pulmonar y la eritrocitosis precede a la enfermedad pulmonar obstructiva crónica en fumadores residentes de grandes alturas
(ARS MÉDICA, 2022)Resumen Introducción: la eritrocitosis excesiva afecta a los habitantes de grandes alturas como La Paz, Bolivia, a 3600 msnm. El objetivo del presente trabajo es determinar la existencia de hipertensión arterial pulmonar ... -

Hormonal and metabolic adjustments during exercise in hypoxia or normoxia in highland natives
(J Appl Physiol, 1996)Abstract In sea-level natives, exposure to hypoxia for a few weeks is characterized by an increased dependence on blood glucose and a decreased reliance on lactate for energy metabolism during exercise. These metabolic ... -
Human physiological adaptation to pregnancy : inter- and intrspecific perspectives
(American Journal of Human Biology, 2003)Abstract. Reproductive success requires successful maternal physiological adaptation to pregnancy. An interspecific perspective reveals that the human species has modified features of our haplorhine heritage affecting ... -
Human visceral leishmaniasis in Bolivia : first proven autochthonous case from "Los Yungas"
(Transactions of The Royal Society of Tropical Medicine and Hygiene, 1983)On 25th February, 1982, a boy aged two years and two months was brought to the Children's Hospital in La Paz with a six-month history of diarrhoea, vomiting, fever and asthenia. On 14th April, a tentative diagnosis of ... -
Hypoglycemia and the origin of hypoxia-induced reduction in human fetal growth
(PLOS One, 2010-01)Abtract. Background: The most well known reproductive consequence of residence at high altitude (HA .2700 m) is reduction in fetal growth. Reduced fetoplacental oxygenation is an underlying cause of pregnancy pathologies, ... -
Hypoxémie et hématocrite dans la polyglobulie pathologique d'altitude = Hypoxaemia and haematocrit in pathological high altitude polycythaemia
(Bull. Eur. Physiopathol. Respir., 1984)Abstract. 81 patients living at La Paz (3,600-4,000 m altitude) and suffering from chronic polycythaemia, with an haematocrit > 57% were studied. They were selected on clinical and spirometric criteria to exclude from the ... -

Identification of a major 72 kilodalton surface antigen in twelve isolates of Leishmania braziliensis braziliensis
(Molecular and Biochemical Parsitology, 1987)The study of the surface antigens of Leishmania braziliensis braziliensis revealed a great homogeneity among ten strains isolated from Bolivia and two reference strains from Brazil and Belize. A 72 kDa major protein, ... -
Identification of cytoplasmic soluble antigens related to the major surface antigens of Leishmania braziliensis braziliensis and L. donovani chagasi
(Parasitol Res., 1990)Abstract. This study describes the identification of aqueous-soluble antigens in Leishmania promastigotes immunologically and biochemically closely related to the major surface antigen. Proteins from surface-iodinated ... -
Identification of Trypanosoma brucei gambiense group I by a specific kinetoplast DNA probe
(Am J Trop. Med. Hyg., 1994)Abstract. A set of 26 Tripanosoma brucei stocks from various African countries, previously characterized by multilocus enzyme electrophoresis (MLEE) for l8 polymorphic loci, have been selected to be representative of the ...
