High altitude hypoxia and blood pressure dysregulation in adult chickens
(Journal of Developmental Origins of Health and Disease, 2013)Although it is accepted that impaired placental perfusion in complicated pregnancy can slow fetal growth and programme an increased risk of cardiovascular dysfunction at adulthood, the relative contribution of reductions ... -
High altitude metahemoglobinemia
([s.n.], 1984)SUMMARY. All high altitudes the human erythrocyte, subject to a permanent hypoxy, is the site of metabolic changes among which metahemoglobin has drawn our attention. The present work presents an. argument in favor of the ... -
High correlation between Chagas' disease serology and PCR-based detection of Trypanosoma cruzi kinetoplast DNA in Bolivian children living in an endemic area
(FEMS Microbiology Letters, 1994)Abstract. The detection of Trypanosoma cruzi kinetoplast DNA by polymerase chain reaction (PCR) amplification is a potentially powerful tool for the parasitological diagnosis of Chagas’ disease. We have applied this technique ... -
High-altitude ancestry protects against hypoxia-associated reductions in fetal growth
(Archives of Disease in Childhood-Fetal and Neonatal, 2007-02-28)Objective: The chronic hypoxia of high-altitude (>2500 m) residence has been shown to decrease birth weight in all populations studied to date. However, multigenerational high-altitude populations appear protected relative ... -
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. ... -
High-altitude haematology : Quechua-Aymara comparisons
(Annals of Human Biology, 1981)Summary. Haematological studies have been carried out al various altitudes between 450 m and 4800 m, on two separate human groups (Quechuas and Aymaras) living in South America. Changes in the haematological parameters ... -
High-altitude hypoxia and echocardiographic indices of pulmonary hypertension in male and female chickens at adulthood
(Circulation Journal, 2014-06)Background: By combining the chick embryo model with incubation at high altitude (HA), the effects of chronic hypoxia on fetal growth, fetal cardiac and aortic wall remodeling and systemic arterial blood pressure at adulthood ... -
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 ...
