La pletismografía como método de apoyo diagnóstico en las enfermedades broncopulmonares en nuestro medio
(Instituto Boliviano de Biología de Altura, 1983)
Resumen.
Se trata de una comunicación preliminar de un estudio que tiene por finalidad establecer, por pletismografía corporal total, parámetros normales de la función respiratoria en personas habitantes de altura (3.600 ...
Capacidad de difusión alvéolo capilar en niños residentes de altura
(Aeronáutica de la Fuerza Aérea Boliviana, 1987)
RESUMEN.
La capacidad de difusión pulmonar (DLCO) para
el monóxido de carbono fue determinada en 125 niños residentes de altura con edades que fluctuaban
entre 4 y 6 años de edad. El estudio fue realizado en
La Paz ...
Efectos del tabaquismo en una población de altura (La Paz- Bolivia 3600 m.)
(Revista Boliviana de Nefrología, 1990)
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 ...
Exaggerated pulmonary hypertension and right ventricular dysfunction in high-altitude dwellers with patent foramen ovale
(Chest, 2015)
There is considerable interindividual variability in pulmonary artery pressure among high-altitude (HA) dwellers, but the underlying mechanism is not known. At low altitude, a patent foramen
ovale (PFO) is present in about ...
The effects of smoking on a high altitude population. (La Paz, Bolivia, 3600m or 12,200ft)
(Tobacco and Health, 1990)
Barometric pressure (PB) decreases with increasing a altitude. Since oxygen concentration is about 21% in the air of
the whole atmosphere, its partial pressure is also 21% of PB. At the altitude of La Paz (3600)m or ...
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 ...
EPR spectroscopic evidence of iron-catalysed free radical formation in chronic mountain sickness : dietary causes and vascualr consequences
(Free Radical Biology and Medicine, 2022)
Abstract
Chronic mountain sickness (CMS) is a high-altitude (HA) maladaptation syndrome characterised by elevated systemic oxidative-nitrosative stress (OXNOS) due to a free radical-mediated reduction in vascular nitric ...
Exaggerated systemic oxidative-inflammatory-nitrosative stress in chronic mountain sIckness is associated with cognitive decline and depression
(J Physiol, 2019)
Abstract.
Chronic mountain sickness (CMS) is a maladaptation syndrome encountered at high altitude (HA) characterised by severe hypoxaemia that carries a higher risk of stroke and migraine and is associated with increased ...
