The highs and lows of programmed cardiovascular disease by developmental hypoxia : studies in the chicken embryo
(J Physiol, 2018)Abstract It is now established that adverse conditions during pregnancy can trigger a fetal origin of cardiovascular dysfunction and/or increase the risk of heart disease in later life. Suboptimal environmental conditions ... -
The impact of altitude on the sleep of young elite soccer players (ISA3600)
(Br J Sports Med, 2013-01-28)Abstract. Background: Altitude training is used by elite athletes to improve sports performance, but it may also disrupt sleep. The aim of this study was to examine the effects of 2 weeks at high altitude on the sleep ... -
The importance of socioeconomic and nutritional conditions rather than altitude on the physical growth of prepubertal Andean highland boys
(Annals of Human Biology, 1994)Summary. The aim of this work was to study the effect of hypoxic stress on the physical growth of prepubertal Bolivian boys (10-11.5 years of age) of the same socioeconomic and nutritional conditions. The subjects consisted ... -
The interest of immunoprecipitation tests in the immunological diagnosis of Chagas'disease
(Ann. Soc. Belge Med. Trop., 1985)Summary. lmmunoelectrophoresis (lEP) and a double diffusion microtest (MD) were evaluated for ¡mmunological diagnosis of Chagas' d¡sease, using 527 sera from Bolivian patients. The specificity of, the tests was given ... -
The microdistribution of isoenzymic strains of Trypanosoma cruzi in southern Bolivia; new isoenzyme profiles and further arguments against Mendelian sexuality
(Transactions of The Royal Society of Tropical Medicine and Hygiene, 1984)Abstract. 132 Trypanosoma cruzi stocks were collected in southern Bolivia (99 stocks in Tupiza, 33 in Tarija), and were characterized using five enzymes (six loci). From these 132 stocks, a sample of 21 was studied using ... -
The nutritional intake of Bolivian boys : the relation between altitude and socioeconomic status
(J. Sports Med., 1994)Abstract. The nutrition of 57 native Bolivian boys living at high altitude (HA) in La Paz (± 4000 m) and of 63 boys living at low altitude (LA) in St. Cruz (± 400 m) is described. The dietary information was obtained with ... -
The origin of Rhodnius prolixus in Central America
(Medical and Veterinary Entomology, 1998)Rhodnius prolixus Stal (Hemiptera, Reduviidae) is the main domestic vector of Chagas disease in Venezuela and Colombia, and also in parts of Central América (El Salvador, Guatemala, Honduras and Nicaragua). In Central ... -
The presence in Bolivia of two distinct zymodemes of Trypanosoma cruzi, circulating sympatrically in a domestic transmission cycle
(Transactions of The Royal Society of Tropical Medicine and Hygiene, 1983)Abstract. The enzyme profiles of 109 Bolivian stocks of Trypanosoma cruzi were determined by cellulose acetate electrophoresis using the four enzymes: malate dehydrogenase (oxaloacetate decarboxylating) (NADP+) (E.C.1.1.1.40, ... -
The pulmonary circulation of high altitude natives
(Springer-Verlag, 1982)Abstract. La Paz, the capital of Bolivia, a city with about 700,000 inhabitants, extends itself from an altitude of 4000 m above sea level down to 3200 m. The altitude of the Bolivian Institute of Altitude Biology (I.B.B.A.) ... -
The regional distribution of pulmonary blood flow in normal high altitude dwellers at 3650 m (12,200 ft) and in chronic mountain sickness
(INTERPRINT PUBLICATIONS, 1975)Summary. Simultaneous isotope dilutaon curves were recorded from the right upper (QRUZ) and right lung zones (QRLZ) by Surface scanning in the sitting and recumbent positions in 15 normal high altitude born males and 3 ... -
The relationship between perinatl hypoxia and sleep-disordered breathing in preclinical chronic mountain sickness
(High Altitude Medicine & Biology, 2010-08-08)Introduction: Chronic intermittent hypoxia due to sleepdisordered breathing is implicated as a potential etiological factor for chronic mountain sickness (CMS). Whether sleepdisordered breathing precedes or results from ... -
The relationship of blood-group type to American cutaneous leishmaniasis
(Annals of Tropical Medicine and Parasitology, 1989)The association of certain human blood groups with parasites is a controversial subject. In some cases positive correlations have been demonstrated, as in schistosomiasis (Pereira et al., 1979) and giardiasis (Barnes and ... -

The role of oxygen in prenatal growth : studies in the chick embryo
(J Physiol, 2007-10-25)The compelling evidence linking small size at birth with later cardiovascular disease has renewed and amplified scientific and clinical interests into the determinants of fetal growth. It is accepted that genes and ... -

The sleep of elite athletes at sea level and high altitude : a comparison of sea-level natives and high-altitude natives (ISA3600)
(Br J Sports Med, 2013-09-03)Abstract. Background: Altitude exposure causes acute sleep disruption in non-athletes, but little is known about its effects in elite athletes. The aim of this study was to examine the effects of altitude on two groups ... -
The use of morphometrics in entomological surveillance of sylvatic foci of Triatoma infestans in Bolivia
(Acta Tropica, 1997)Abstract Jamach'uma (Cochabamba, Bolivia) is a small village surrounded by sylvatic foci of Triatoma infestans. Houses in the village were also infested with T. infestans, and were sprayed in December 1992 as part of a ... -
