Caracterización genética de rattus norvegicus "Sprague-Dawley" del Bioterio del Instituto Boliviano de Biología de la Altura de La Paz, Bolivia
(Ciencia al Día, 2016-12)
RESUMEN.
Las colonias no consanguíneas de ratas Sprague-Dawley se caracterizan por poseen un alto grado de variabilidad genética pero estas colonias son cerradas y con el paso del tiempo llegan a cambiar su estructura ...
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 ...
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 ...
Introducing hydro-climatic extremes and human impacts in Bolivia, Paraguay and Uruguay
(Springer, 2016)
Abstract.
Climate change and ENSO events are increasing hydro-climatic risks and health impacts in Bolivia, Paraguay and Uruguay, as well as social inequalities in Bolivia and Paraguay. Climate scenarios project increase ...
Autosomal and X chromosome alu insertions in Bolivian aymaras and quechuas : two languages and one genetic pool
(American Journal of Human Biology, 2010)
Abstract.
Thirty-two polymorphic Alu insertions (18 autosomal and 14 from the X chromosome) were studied in
192 individuals from two Amerindian populations of the Bolivian Altiplano (Aymara and Quechua speakers: the two ...
Predicting sickness during a 2-week soccer camp at 3600 m (ISA 3600)
(Br J Sports Med, 2013-08-23)
Abstract.
Objectives. To examine the time course of changes in
wellness and health status markers before and after
episodes of sickness in young soccer players during a
high-altitude training camp (La Paz, 3600 ...
Overview of how ecosystem changes can affect human health
(ELSEVIER, 2011)
Ecosystem changes can affect human health in several forms, most of them indirectly. Degraded ecosystems can affect water quality and availability, and cause a decrease in food production, climatic instability, poor ...
Respuestas fisiológicas divergentes en ratas y ratones de laboratorio criadas a gran altitud
(COLEGIO MEDICO DE BOLIVIA, 2016-02)
Estudios ecológicos muestran que los ratones viven a gran altitud (GA) (Alturas - hasta 4000 m),
mientras que las ratas están ausentes en estas altitudes, y no existen datos que expliquen esta
diferencia. Utilizamos ratas ...
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 ...
Do cytokines contribute to the andean-associated protection from reduced fetal growth at high altitude?
(Reproductive Sciences, 2011)
Abstract.
Pro- versus anti-inflammatory cytokine balance is important for successful pregnancy. Chronic hypoxia alters cytokine levels and increases the frequency of fetal growth restriction (FGR). Multigenerational Andean ...
