Resistance and capacitance vessels of the skin in permanent and temporary residents at high altitude
(Centre National de la Recherche Scientifique, 1971)Summary. Blood flow, pressure and volume have been measured in the right hand as a representative cutaneous vascular bed. Measurements have been made at sea level and at high altitude on residents and newcomers. Blood ... -
Respiratory and cardiocirculatory responses of acclimatization of high altitude natives (La Paz, 3500 m) to tropical lowland (Santa Cruz, 420 m)
(Springer-Verlag, 1982)Abstract. Socioeconomic development of the countries of the Andean region necessitates massive migration of population groups through colonization programs, which mobilize high altitude natives as well as low- landers. ... -
Respiratory and hematological adaptations of young and older aymara men native to 3600M
(American Journal of Human Biology, 1992)ABSTRACT. This paper reports the results of a study designed to test the hypothesis that an inevitable concomitant of aging at high altitudes is chronic mountain sickness resulting from excess erythrocytosis secondary ... -
Respiratory nitric oxide and pulmonary artery pressure in children of aymara and european ancestry at high altitude*
(CHEST, 2008-11-07)Invasive studies suggest that healthy children living at high altitude display pulmonary hypertension, but the data to support this assumption are sparse. Nitric oxide (NO) synthesized by the respiratory epithelium regulates ... -
Response to letters regarding article, "Pulmonary and systemic vascular dysfunction in young offspring of mothers with preeclampsia"
(Circulation, 2011)We thank Lazdam et al and Yuan et al for their interesting comments on our study.1 Lazdam et al point out that in our study, birth weight in offspring of mothers with preeclampsia was significantly lower than in controls, ... -
Response to the CO2 and buccal inspiratory pressure as an expression of the diaphragmatic contraction in subjects with eritrocitosis pathology of altitude
(Acta Andina, 1996)The designation Eritrocitosis Patolócia de Altura (EPA)” commonly known as “Poliglobulia of Altitude”, shows characteristics that differentiates it from other pathologies, among them the absence of functional respiratory ... -
Respuesta al anhídrido carbónico y presión bucal inspiratoria como expresión de la contracción diafragmática en sujetos con eritrocitosis patológica de altura (EPA)
(Revista de la Facultad de Medicina, 1997)La denominada Eritrocitosis Patológica de Altura (EPA), comúnmente conocida como "Poliglobulia de Altura", muestra características que la diferencian de otros cuadros, entre ellas la ausencia de trastornos funcionales ... -
Respuesta electroencefalográfica en la altitud en el curso de la hiperventilación voluntaria
(Instituto Boliviano de Biología de Altura, 1970)Se sabe que la hiperventilación voluntaria (H.V.) produce una caída de la presión parcial del CO2 (PaCO2) y una alcalosis gaseosa que se expresa por una elevación del pH sanguíneo que se acompaña en ciertos casos de ... -
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 ... -
La reversibilidad a la metahemoglobinización de los hematíes en las poblaciones indígenas del corredor interandino. Ensayo de interpretación
(Instituto Boliviano de Biología de Altura, 1970)RESUMEN. Habiendo constatado la metahemoglobinosis con una frecuencia anormalmente elevada, se puede interpretar como un fenómeno adaptativo. Los altiplanides ofrecen características adaptativas muy adelantadas, observándose ... -
Réflexe d'Hoffmann en hypoxie aigue et chronique
(Universidad Mayor de San Andrés, 1970)RESUMEN. La actividad refleja en el hombre sometido a una hipoxia aguda o crónica ha tenido resultados contradictorios. En el hombre nativo de la altura, se ha visto que reacciona en forma diferente con relación a los ... -
Résultats préliminaires en faveur d'une relation faible ou inexistante entre les formes cliniques de la maladie de Chagas et les souches isoenzymatiques de Trypanosoma cruzi
(C.R. Acad. Sc., 1985)MEDICINE AND THERAPEUTICS. Preliminary results in favour of a weak or non-existent relationship between the clinical forms of Chagas'disease and Trypanosoma cruzi isozymic strains. Trypanosoma cruzi stains obtained by ... -
Résultats préliminaires en faveur de l'existence d'un antigène majeur de surface, spècifique de Leishmania braziliensis braziliensis
(C.R. Acad. Sc., 1986)L'étude comparative des antigénes de surface de l0 souches boliviennes clonées et d'une souche brésilienne de référence de la sous-espèce L. b. braziliensis a permis de mettre en évidence une grande homogénéité au sein de ... -
Risk factors for onset of cutaneous and mucocutaneous Leishmaniasis in Bolivia
(American Journal Tropical Medicine and Hygiene, 1997)Abstract. A survival analysis was performed on data from an endemic area of Bolivia where two populations, natives and highland migrants, were living, to investigate risk factors for onset of cutaneous leishmaniasis (CL) ... -

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 ... -
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 ... -
