Présence en Bolivie de sept nouveaux variants isoenzymatiques de Trypanosoma cruzi. Considérations taxonomiques et épidémiologiques. Discussion sur la valeur antigénique potentielle de certaines isoenzymes
(Cah. O.R.S.T.O.M., 1983)Abastract. Les auteurs décrivent la variabilité génétique de 45 isolats boliviens de Trypanosoma cruzi à l’aide de 12 loci isoenzymatiques. Ils montrent la présence de deux groupes principaux, avec cependant une importante ... -
El problema de la adaptación de la circulación cerebral en la altura
(Instituto Boliviano de Biología de Altura, 1970-11)De todos los órganos, el cerebro es el más sensible a la carencia de oxígeno y de glucosa. Su funcionamiento normal necesita un aporte constante y regular de los metabolitos fundamentales. Por debajo de un cierto umbral ... -
Programmation prénatale de l'acclimatation hématologique et respiratoire chez des rats de haute altitude
(Actas Club Recherché Clinique de Quebec, 2011)Nous avons testé l’hypothèse selon laquelle l’hypoxie prénatale chez le rat aurait des conséquences à long terme sur l’acclimatation physiologique à la haute altitude. Des rats vivant en haute altitude (3600m, La Paz, ... -
Propositon of a standard description for phlebotomine sandflies
(Parassitologia, 1991)Abstract. In order to be comparable, and efficient, the descriptions need to be as complete as possible and realized according to the same parameters. In this respect, we present the standard description of Phlebotomine ... -
Propuesta de descripción : tipo para los flebótomos grupo CIPA
(Acta Andina, 1993)Resumen. La descripción de los Flebótomos, algunos de los cuales son vectores de la Leishmaniasis, bartonelosis y virus precisa que ésta sea lo más completa posible y evaluando los mismos parámetros. Tal requerimiento ... -
Protective effect of female sex hormones against pulmonary hypertension in Bolivian high altitude natives
(High Altitude Medicine & Biology, 2003-02-19)There is abundant evidence that female sex hormones have protective effects in the systemic circulation in both animals and humans, but little is known regarding their role in the regulation of the pulmonary circulation. ... -
Prueba de caminata de 6 minutos en residentes nativos de gran altura
(Rev Med Inst Mex Seguro Soc., 2023)Resumen Introducción: La prueba de caminata de 6 minutos es de amplio uso y evalúa la capacidad funcional para realizar ejercicio submáximo, se desconoce su comportamiento en residentes jóvenes sanos nativos de gran ... -

Pulmonary and systemic vascular dysfunction in young offspring of mothers with preeclampsia
(Circulation, 2010-07-19)Background—Adverse events in utero may predispose to cardiovascular disease in adulthood. The underlying mechanisms are unknown. During preeclampsia, vasculotoxic factors are released into the maternal circulation by the ... -
Pulmonary diffusing capacity in young andean highland children
(Respiration, 1982)Abstract. Lung diffusing capacities for carbon monoxide were measured in 125 highland Andean children between 4 and 6 years of age in La Paz, Bolivia (3,650 m), using a steady-state technique. Male children had a significantly ... -
Pulmonary gas exchange and acid-base state at 5,260 m in high-altitude Bolivians and acclimatized lowlanders
(J Appl Physiol, 2002)Pulmonary gas exchange and acid-base state were compared in nine Danish lowlanders (L) acclimatized to 5,260 m for 9 wk and seven native Bolivian residents (N) of La Paz (altitude 3,600–4,100 m) brought acutely to this ... -
Pulmonary gas exchange in Andean nativos with excessive polycythemia - efecct of hemodilution
(J. Appl. Physiol., 1988)Pulmonary gas exchange in andean natives (n =8) with excessive high-altitude (3,600-4,200 m) polycythemia (hematocrit 65.1 +- 6.6%) and hipoxemia (arterial PO2 45.6+-5.6 Torr) in the absence of pulmonary or cardiovascular ... -
Pulmonary gas exchange, diffusing capacity in natives and newcomers at high altitude
(Respiration Physiology, 1978)Abstract. At high altitude, in resting conditions, no differences have been observed between High Altitude Natives (HAN) and acclimatized Sea Level Natives (SLN) in AaDo₂, aADco₂ or venous admixture. In acclimatized SLN, ... -
Pulmonary hypertension in high-altitude chronic hypoxia : response to nifedipine
(European Respiratory Journal, 1998-11)ABSTRACT. Permanent residents at high altitude may develop excessive polycythaemia (H-Hb) and pulmonary hypertension, which often leads to cardiac failure. Inhibitors of calcium channels have been shown to reverse pulmonary ... -
Pulmonary hypertension in high-altitude dwellers : novel mechanisms, unsuspected predisposing factors
(Adv Exp Med Biol., 2006)Abstract Studies of high-altitude populations, and in particular of maladapted subgroups, may provide important insight into underlying mechanisms involved in the pathogenesis of hypoxemia-related disease states in general. ... -
Pulmonary nitric oxide in mountain dwellers
(NATURE, 2001-11-22)Nitric oxide is synthesized in the lungs to help regulate blood flow, and its levels have been found to drop in species native to low altitudes, including humans, upon acute exposure to reduced oxygen concentration1–3. ... -
Pulmonary-artery pressure and exhaled nitric oxide in Bolivian and caucasian high altitude dwellers
(High Altitude Medicine & Biology, 2008)Abstract. There is evidence that high altitude populations may be better protected from hypoxic pulmonary hypertension than low altitude natives, but the underlying mechanism is incompletely understood. In Tibetans, ... -
