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 ...
Adaptación cardiocirculatoria a la hipoxia crónica : estudio comparativo del débito coronario, rendimiento y consumo de oxígeno del miocardio, entre los residentes del nivel del mar y los de las grandes alturas
(Instituto Boliviano de Biología de Altura, 1973)
Resumen.
La adaptación a la hipoxia y la resistencia al esfuerzo de las personas que viven en el altiplano de los Andes y del Himalaya han intrigado desde hace mucho tiempo a fisiólogos y clínicos. Un estudio sobre el ...
Cerebral glucose metabolism and cerebral blood flow in high-altitude residents
(Journal of Applied Physiology, 1974)
The present study was performed to evaluate the hypothesis that an increased H+ production by the brain from lactic acid formation during hypoxia a role in the lowering of the bicarbonate concentration. Twenty –three ...
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 ...
Divergent physiological responses in laboratory rats and mice raised at high altitude
(The Journal of Experimental Biology, 2015-01-29)
Abstract.
Ecological studies show that mice can be found at high altitude (HA – up to 4000 m) while rats are absent at these altitudes, and there are
no data to explain this discrepancy. We used adult laboratory rats ...
Chémosensibilité à l'anhydride carbonique chez l'homme en hypoxie aiguë et chronique
(Journal de Physiologie, 1968)
Point de rupture d'apnée volontaire au cours des hypoxies chronique et aiguë
(Journal de Physiologie, 1968)
Exposición crónica a la altura. Características clínicas y diagnóstico
(Arch Cardiol Mex, 2021)
Resumen
La exposición crónica a la altitud se ha asociado a hipoxia hipobárica en quienes la experimentan. Dos entidades se han asociado a la hipoxia hipobárica: la hipertensión pulmonar de la alta altitud y el mal de ...
Preeclampsia and risk of maternal pulmonary hypertension at high altitude in Bolivia
(Journal of Developmental Origins of Health and Disease, 2023)
Abstract.
Women with a history of preeclampsia (PE) have a greater risk of pulmonary arterial hypertension (PAH). In turn, pregnancy at high altitude is a risk factor for PE. However, whether women who develop PE during ...
The highs and lows of programmed cardiovascular disease by developmental hypoxia : studies in the chicken embryo
(J Physiol, 2018)
Abstract
It is now established that adverse conditions during pregnancy can trigger a fetal origin of cardiovascular dysfunction and/or increase the risk of heart disease in later life. Suboptimal environmental conditions ...
