Glicólisis del glóbulo rojo humano en la hipoxia crónica de altura
(Instituto Boliviano de Biología de Altura, 1987)Resumen. Hemos encontrado que la glicólisis de los glóbulos rojos humanos bajo condiciones de hipoxia, está relacionado con los cambios en la actividad y niveles de enzyma de varios intermedios metabólicos. La sensibilidad ... -
Gradiente alvéolo-arterial de oxígeno en nativos de la altura
(Instituto Boliviano de Biología de Altura, 1970)Resumen. La diferencia de tensión alveolo-arterial para el oxígeno fué determinado a 3 niveles de oxigenación, en 3 grupos de sujetos: 1. Personas normales del nivel del mar 2. Nativos andinos normales de la altura 3. ... -
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 ... -
Greater uterine artery blood flow during pregnancy in multigenerational (Andean) than shorter-term (European) high-altitude residents
(Am J Physiol Regul Integr Comp Physiol, 2007)Multigenerational (Andean) compared with shorter-term (European) high-altitude residents exhibit less hypoxia-associated reductions in birth weight. Because differences in arterial O2 content are not responsible, we ... -
Growth in knee heel length and recumbent length during the weaning period (4-7 months) in less developed countries
(Humanbiol, 1994)Abstract. Early infancy is a highly sensitive period for the development of stunting. Growth in knee heel length and in recumbent length was followed monthly from the age of 4 to 7 months in an urban area of Brazzaville, ... -
Habitual physical activity in 10- to 12-year-old Bolivian boys : the relation between altitude and socioeconomic status
(J. Sports Med., 1994)Abstract. This study describes habitual physical activity (HPA) of Bolivian boys living at different altitudes and form different socioeconomic status. The boys were living at high altitude (HA) in La Paz (4000 m) and at ... -
Haematology and erythrocyte metabolism in man at high altitude : an aymara-quechua comparison
(American Journal of Physical Anthroplogy, 1985)ABSTRACT. In the course of haematological and biological investigations among Aymara and Quechua populations in Bolivia, an anthropological study of the erythrocytary respiratory function was carried out on the two ... -
Haemoglobin concentration and lung diffusing capacity in man at low high altitude
(Compterendus des séances de la Société de Biologie, 1982)Resumen. Lung diffusing capacity (DLCO) was measured using a steady state method in high (3600 m.) and sea level natives. Correlation was found between DLCO, height, age and haemoglobin concentration. Regression coefficients ... -
Hallazgos de función pulmonar en pacientes con EPOC a 3.600 m.s.n.m. en el Instituto Boliviano de Biología de Altura
(COLEGIO MEDICO DE BOLIVIA, 2016-02)RESUMEN. El instituto Boliviano de Biología de Altura (IBBA) a parte de la investigación realiza venta de servicios de pruebas de Función Pulmonar a diferentes centros de salud, considerado centro de referencia a nivel ... -
Hallazgos ecocardiográficos (Modo "M") en la insuficiencia aórtica aguda, severa por endocarditis infecciosa. Reporte de cuatro casos clínicos
(Instituto Boliviano de Biología de Altura, 1983)Abstract. Echocardiography has greatly enhanced our ability of early diagnosis and appropriate treatment of this group of patients. Echocardiographic of four patients with acute aortic regurgitation who subsecuently died, ... -
Hallazgos electrocardiográficos y ecocardiográficos en niños normales nativos de la altura (3.650 m.)
(Instituto Boliviano de Biología de Altura, 1987)Resumen. Con la finalidad de establecer los parámetros electrocardiográficos y ecocardiográficos en niños normales nativos de la altura (3.650 m.), así como el grado de correlación con parámetros similares en niños del ... -
Heat exchange and energetic balance during exercise in highlanders and lowlanders at sea level and high altitude
(Environmental Physiology, 1973)This study was designer to determine the effects of changes in both cutaneous circulation (15) and kinetics of oxygen uptake (20) at high altitude on mechanisms of heat exchange during exercise. From a theoretical point ... -
Helping patterns and reproductive success in Aymara communities
(American Journal of Human Biology, 2002)Abstract. “Helpers at the nest,” young adults remaining in their parents home to take care of younger siblings, are known in many species of birds and mammals. Similar behaviors are occasionally observed in human societies ... -
Hematocrit and hemoglobin levels at adulthood are determined by neonatal hypoxic exposure in rats living at high altitude
(High Altitude Medicine & Biology, 2010-08-08)Introduction: In previous work performed at sea level we reported that exposure to neonatal hypoxia impairs ventilatory and hematological responses to chronic hypoxia later in life. These findings supported the hypothesis ... -
