Acute hypoxia-reoxygenation and vascular oxygen sensing in the chicken embryo
(Physiological Reports, 2017)
Abstract.
Fetal/perinatal hypoxia is one of the most common causes of perinatal morbidity and mortality and is frequently accompannied by vascular dysfunction. However, the mechanisms involved have not been fully delineated. ...
Células endoteliales y trombosis en la altura
(Revista Médica, 2005)
RESUMEN
Es bastante conocido que la hipoxia crónica produce reacciones tanto Biológicas como Fisiológicas. En estudios sobre la fisiología de la coagulación se han observado actividades diferentes sobre este mecanismo en ...
Síndromes clínicos en la infección aguda y crónica de la COVID-19 en población nativa y residente de altura durante la primera y segunda ola
(Horiz Med (Lima), 2023)
RESUMEN
Objetivo: Clasificar los síntomas de la infección aguda y crónica de la COVID-19 en síndromes clínicos, en un grupo poblacional que vive en altura, durante la primera y segunda ola. Materiales y métodos: Estudio ...
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 ...
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 ...
Neonatal oxygenation, pulmonary hypertension, and evolutionary adaptation to high altitutde (2013 Grover Conference series)
(Pulm Circ, 2015-03)
Abstract.
Andeans and Tibetans have less altitude reduction in birth weight than do shorter-resident
groups, but only Tibetans are protected from pulmonary hypertension and chronic mountain sickness
(CMS). We hypothesized ...
Pulmonary and systemic vascular dysfunction in young offspring of mothers with preeclampsia
(Circulation, 2010-07-19)
Background—Adverse events in utero may predispose to cardiovascular disease in adulthood. The underlying mechanisms are unknown. During preeclampsia, vasculotoxic factors are released into the maternal circulation by the ...
Determinants of blood oxygenation during pregnancy in Andean and Europeas residents of high altitude
(Am J Physiol Regul Integr Comp Physiol, 2007-07-02)
High altitude decreases birth weight,
but this effect is diminished in long vs. short-resident, high-altitude
populations. We asked whether women from long vs. short-resident,
high-altitude populations had higher arterial ...
Valores hematológicos normales en personas sanas a 4.000 metros en Bolivia
(BIOLOGÍA Y ALTURA, 2007)
Resumen.
Los valores normales hematológicos de salud para las personas que viven a 4,000 m en Bolivia, según el libro
de Biología Médica de altura 2:361-367, 2001 - Es definido que el hematocrito normal y los niveles ...
Dopaminergic metabolism in carotid bodies and high altitude acclimatization in female rats
(Am J Physiol Relulatory, 2002-04)
We tested
the hypothesis that ovarian steroids stimulate breathing
through a dopaminergic mechanism in the carotid bodies (CB). In
ovariectomized female rats raised at sea level, domperidone,
a peripheral D2 receptor ...
