Concentración de Malondialdehido en sujetos que residen a gran altitud : estudio exploratorio
(Rev Peru Med Exp Salud Pública, 2017-12-07)
Resumen. El objetivo fue investigar el comportamiento del malondialdehido (MDA), biomarcador de estrés oxidativo, a grandes altitudes (3500–4200 m de altitud). Se realizó un estudio exploratorio en 91 sujetos de las ciudades ...
Sleep-disordered breathing and oxidative stress in preclinical chronic mountain sickness (excessive erythrocytosis)
(Respiratory Physiology & Neurobiology, 2013-01-22)
Abstract.
Chronic mountain sickness (CMS) is considered to be a loss of ventilatory acclimatization to high
altitude (>2500 m) resulting in marked arterial hypoxemia and polycythemia. This case-control
study explores ...
Estrés oxidativo por exposición crónica a la altura y al monóxido de carbono por uso de leña
(COLEGIO MEDICO DE BOLIVIA, 2016-02)
RESUMEN.
El estrés oxidativo, es un desequilibrio propiciado por la producción excesiva de radicales libre y la deficiencia del sistema antioxidante. Los radicales libres son especies químicas que poseen un electrón ...
Influencia de la hipoxia intermitente en el mal crónico de montaña y su implicancia en la terapéutica
(COLEGIO MEDICO DE BOLIVIA, 2016-02-24)
Potential role for elevated maternal enzymatic antioxidant status in Andean protection against altitude-associated SGA
(The Journal of Maternal-Fetal and Neonatal Medicine, 2012)
Oxidative stress has been implicated in the uteroplacental
ischemia characteristic of preeclampsia and small-for-gestational-age (SGA) birth, both of which are more common at high
(>2500 m) vs low altitude. Since Andeans ...
Divergent mitochondrial antioxidant activities and lung alveolar architecture in the lungs of rats and mice at high altitude
(Frontiers in Physiology, 2018)
Abstract.
Compared with mice, adult rats living at 3,600 m above sea level (SL—La Paz, Bolivia) have high hematocrit, signs of pulmonary hypertension, and low lung volume with reduced alveolar surface area. This phenotype ...
Erythropoietin and caffeine exert similar protective impact against neonatal intermittent hypoxia : apnea of prematurity and sex dimorphism
(Experimental Neurology, 2019)
Abstract.
Apnea of prematurity (AoP) is associated with severe and repeated episodes of arterial oxygen desaturation (intermittent hypoxia - IH), which in turn increases the number of apneas. So far, there is no data ...
