Metahemoglobinemia de altura. Metahemoglobina = reverva de hemoglobina
(Revista Sociedad Latinoamericana de Hematología, 1979)
Resumen.
En las grandes alturas, el eritrocito humano sometido a una hipoxia permanente, es el sitio de modificaciones metabólicas entre las cuales la metahemoglobinemia ha retenido nuestra atención. En el presente trabajo ...
Instituto Boliviano de Biología de Altura, razones de su creación y funcionamiento
(Instituto Boliviano de Biología de Altura, 1988)
Pocos territorios situados en regiones elevadas en el mundo son tan accesibles, como los Andes, al estudio de poblaciones residentes en permanencia. Bolivia situada en el corazón de América tiene en La Paz, y otros centros ...
Factores predominantes en la etiopatogenia de la enfermedad de Monge (EPA) en La Paz, Bolivia (3.600 - 4.000 m.)
(IFEA, 1993)
Resumen.
Se presenta una síntesis de los principales estudios de la función respiratoria en pacientes portadores de la “Enfermedad de Monge” o Eritrocitosis Patológica de Altura (EPA), entidad nosológica de carácter ...
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 ...
Graduated effects of high-altitude hypoxia and highland ancestry on birth size
(Pediatric Research, 2013-10-02)
Background: We present a cohort of ca. 25,000 birth
records from Bolivia of men and women who are currently
adults. We used this cohort to test the hypothesis that high
altitude reduces birth weight and that highland ...
Andean and Tibetan patterns of adaptation to high altitude
(American Journal of Human Biology, 2013-01-24)
Objectives: High-altitude hypoxia, or decreased oxygen levels caused by low barometric pressure, challenges the
ability of humans to live and reproduce. Despite these challenges, human populations have lived on the Andean ...
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 ...
Where the O2 goes to : preservation of human fetal oxygen delivery and consumption at high altitude
(The Journal of Physiology, 2009)
Fetal growth is decreased at high altitude (> 2700 m). We hypothesized that variation in fetal O2
delivery might account for both the altitude effect and the relative preservation of fetal growth in
multigenerational ...
Efectos del tabaquismo en una población de altura (La Paz- Bolivia 3600 m.)
