Role of cytokines in altitude-associated preeclampsia
(Pregnancy Hypertens, 2012-01)
Abstract.
Background: Preeclampsia (PE) is more common at high than low altitude and contributes
to the altitude-related decline in birth weight. Since inflammatory markers are implicated
in PE, we asked if such markers ...
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 ...
Maternal and fetoplacental hypoxia do not alter circulating angiogenec growth effectors during human pregnancy
(Biol Reprod., 2014-02-27)
Abstract.
One causal model of preeclampsia (PE) postulates that
placental hypoxia alters the production of angiogenic growth
effectors (AGEs), causing an imbalance leading to maternal
endothelial cell dysfunction. We ...
Gases en sangre
(s.n., 1986)
La hematosis constituye una importante etapa fisiológica en el curso de la cual se efectúan los intercambios gaseosos entre la sangre que llega por los capilares pulmonares y el medio gaseoso intra-alveolar, es decir la ...
Uterine artery blood flow, fetal hypoxia and fetal growth
(Philosophycal Transactions B, 2015-03-13)
Evolutionary trade-offs required for bipedalism and brain expansion influence
the pregnancy rise in uterine artery (UtA) blood flow and, in turn, reproductive
success. We consider the importance of UtA blood flow by ...
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 ...
Human physiological adaptation to pregnancy : inter- and intrspecific perspectives
(American Journal of Human Biology, 2003)
Abstract.
Reproductive success requires successful maternal physiological adaptation to pregnancy. An interspecific perspective reveals that the human species has modified features of our haplorhine heritage affecting ...
La investigación médica francesa y el Instituto Boliviano de Biología de Altura
(CRONICA AGUDA, 1988-07)
Hasta hace 25 años, nuestro país estuvo ausente del grupo, científico mundial que estudia los problemas relacionados con la hipoxia de altura. En ocasión de la visita del Presidente francés, Charles de Gaulle, se firmó un ...
Role of genetic and environmental factors in the increased blood pressures of Bolivian blacks
(American Journal of Human Biology, 1999)
Abstract.
The tendency toward hypertension or higher blood pressure is more common in blacks than whites. The factors that account for these differences are attributed to both environmental and genetic factors. To clarify ...
