  • Absence of work efficiency differences during cycle ergometry exercise in Bolivian Aymara 

    Brutsaert, Tom D; Haas, Jere D; Spielvogel, Hil (High Altitude Medicine & Biology, 2004)
    ABSTRACT This study tested the hypothesis that Andean natives are adapted to high altitude (HA) via high work ef ficiency during exercise in hypoxia. A total of 186 young males and females were tested in Bo livia, ...
  • Acute hypoxia-reoxygenation and vascular oxygen sensing in the chicken embryo 

    Mohammed, Riazuddin; Salinas, Carlos E; Giussani, Dino A; Blanco, Carlos E; Cogolludo, Angel L; Villamor, Eduardo (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. ...
  • Adrenergic system in high altitude residents 

    Antezana, AM; Richalet, JP; Antezana, G; Spielvogel, H; Kacimi, R (Int. J Sports. Med, 1992)
    Heart rate (HR) response to isoproterenol (ISO) infusion (IP) is decreased in normal sea level (SL) natives exposed to high altitude (HA). Since norepinephrine plasma concentration is higher in HA hypoxia, a downregulation ...
  • Adrenocortical suppression in highland chick embryos is restored during incubation at sea level 

    Salinas Salmón, Carlos E; Villena, Mercedes; Blanco, Carlos E; Giussani, Dino A (High Altitude Medicine & Biology, 2011)
    Abstract Salinas, Carlo E., Mercedes Villena, Carlos E. Blanco, and Dino A. Giusssani. Adrenocortical suppression in highland chick embryos is restored during incubation at sea level. High Alt. Med. Biol. 12:79–87, ...
  • Augmented uterine artery blood flow and oxygen delivery protect andeans from altitude-associated reductions in fetal growth 

    Julian, Colleen Glyde; Wilson, Megan J; Lopez, Miriam; Yamashiro, Henry; Tellez, Wilma; Rodriguez, Armando; Bigham, Abigail W; Shriver, Mark D; Rodriguez, Carmelo; Vargas, Enrique; Moore, Lorna G (Am J Physiol Regul Integr Comp Physiol, 2009-02-20)
    A b s t r a c t The effect of high altitude on reducing birth weight is markedly less in populations of high- (e.g., Andeans) relative to low-altitude origin (e.g., Europeans). Uterine artery (UA) blood flow is greater ...
  • Capacidad aeróbica de deportistas de diferentes disciplinas 

    Soria, R; Spielvogel, H (COLEGIO MEDICO DE BOLIVIA, 2016-02)
    RESUMEN OBJETIVOS.- Comprobar si el efecto de la hipoxia de altura repercute de la misma manera en las disciplinas deportivas al margen de su predominancia respecto a la dependencia del oxígeno. MATERIAL Y METODOS.- El ...
  • Chemoreflex ventilatory response to CO₂ in man at low and high altitudes 

    Lefrançois, R; Gautier, H; Pasquis, P; Cevaer, AM; Hellot, MF; Leroy, J (Respiration Physiology, 1972)
    Abstract. On man, a peripheral chemoreflex ventilatory response curve was obtained by measuring ventilatory reactions to the transient inhalation of a CO₂-rich mixture. Experiments have been performed. 1) on lowlanders ...
  • Concentración de Malondialdehido en sujetos que residen a gran altitud: estudio exploratorio 

    Melgarejo Pomar, Ingrid Gaby; Balanza Erquicia, Elfride; Torrez Colmena, Lizeth; Quisberth Barrera, Sergio; Suzaño Vargas, Pilar Leina (Rev Peru Med Exp Salud Pública, 2017-12-07)
    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 de La ...
  • Consensus statement on chronic and subacute high altitude diseases 

    León-Velarde, Fabiola; Maggiorini, Marco; Reeves, John T; Aldashev, Almaz; Asmus, Ingrid; Bernardi, Luciano; Ge, Ri-Li; Hackett, Peter; Kobayashi, Toshio; Moore, Lorna G; Peñaloza, Dante; Richalet, Jean-Paul; Roach, Robert; Wu, Tianyi; Vargas, Enrique; Zubieta-Castillo, Gustavo; Zubieta-Calleja, Gustavo (High Altitude Medicine & Biology, 2005)
    ABSTRACT This is an international consensus statement of an ad hoc committee formed by the In ternational Society for Mountain Medicine (ISMM) at the VI World Congress on Mountain Med icine and High Altitude Physiology ...
  • Desadaptación crónica a la vida en la altura 

    Villena Cabrera, Mercedes (Anales de la Academia Boliviana de Medicina, 2004)
    Cuando humanos o animales son transportados del nivel del mar a alturas elevadas, son expuestos a una presión disminuida de oxígeno. Como consecuencia se ponen en marcha procesos que se pueden denominar de aclimatación y ...
