Andean compared with european women are protected from altitude-associated intrauterine growth restriction (IUGR)
(s.n., 2003)
Abstract.
Babies born at high altitude to long-term high-altitude residents weigh more than those of recent migrants from low altitude. Objective: We asked whether a gradient exists such that persons of Andean ancestry ...
Ancient human genomes suggest three ancestral populations for present-day Europeans
(Nature, 2014-09-18)
We sequenced the genomes of a 7,000-year-old farmer from Germanyandeight 8,000-year-oldhunter-gatherersfromLuxembourg and Sweden. We analysed these and other ancient genomes1–4 with

Oxidative-nitrosative stress and systemic vascular function in highlanders with and without exaggerated hypoxemia
(CHEST, 2013-02-01)
Background: Acute exposure to high altitude stimulates free radical formation in lowlanders, yet
whether this persists during chronic exposure in healthy, well-adapted and maladapted highlanders suffering from chronic ...
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 ...
Sleep-disordered breathing and vascular function in patients with chronic mountain sickness and healthy high-altitude dwellers
(CHEST, 2016-11-05)
BACKGROUND: Chronic mountain sickness (CMS) is often associated with vascular
dysfunction, but the underlying mechanism is unknown. Sleep-disordered breathing (SDB)
frequently occurs at high altitude. At low altitude, ...
Genetic variations in the TP53 pathway in native americans strongly suggest adaptation to the high altitudes of the andes
(PLOS One, 2015-09-18)
The diversity of the five single nucleotide polymorphisms located in genes of the TP53 pathway (TP53, rs1042522; MDM2, rs2279744; MDM4, rs1563828; USP7, rs1529916; and
LIF, rs929271) were studied in a total of 282 individuals ...
Determinación de distancia recorrida y variación de parámetros respiratorios y cardiovasculares, antes y después de la prueba de caminata de 6 minutos, en nativos y residentes permanentes de altura clinicamente sanos
(Rev Med (La Paz), 2014-01)
Objetivo:Determinar la distancia recorrida y la variación de parámetros respiratorios
y cardiovasculares antes y después de la prueba de caminata de los 6 minutos
(PC6M) en nativos y residentes permanentes de la altura ...
Aportes de la pletismografía corporal total al estudio de la adaptación respiratoria a la vida en altura
(Universidad Mayor de San Andrés, 1990)
Resumen.
Los procesos de adaptación a la vida en la altura son permanentemente estudiados y el avance de la tecnología, permite conocer aspectos cada vez más novedosos. El objetivo del estudio de parámetros respiratorios ...
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 ...
