On a preliminary screening, substantial leishmanicidal activity was observed for the petroleum ether and alkaloidal extracts of the stem bark of Unonopsis buchtienii, the alkaloids and sterols isolated from these were studied. Of the alkaloids, liriodenine exhibited the highest activity against Leishmania major and L. ... | Antiprotozoal activity of aporphine alkaloids isolated from Unonopsis buchtienii (Annonaceae) | LEISHMANIASIS|UNONOPSIS BUCHTIENII|ANNONACEAE |
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 altitude. We evaluated normalcy of arterial pH and assessed pulmonary gas exchange and acid-base bala... | Pulmonary gas exchange and acid-base state at 5,260 m in high-altitude Bolivians and acclimatized lowlanders | HIPOXIA|VENTILACIÓN|EQUILIBRIO ÁCIDO-BASE|CAPACIDAD DE DIFUNSIÓN |

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 asked whether greater pregnancy-associated increases in uterine artery (UA) blood flow and O2 delivery we... | Greater uterine artery blood flow during pregnancy in multigenerational (Andean) than shorter-term (European) high-altitude residents | PESO AL NACER|ADAPTACIÓN GENÉTICA|HIPOXIA|RESISTENCIA UTEROPLACENTAL VASCULAR |
Abstract. The detection of Trypanosoma cruzi kinetoplast DNA by polymerase chain reaction (PCR) amplification is a potentially powerful tool for the parasitological diagnosis of Chagas' disease. We have applied this technique in a field situation in Bolivia, where 45 children from a primary school were subjected to ser... | High correlation between Chagas' disease serology and PCR-based detection of Trypanosoma cruzi kinetoplast DNA in Bolivian children living in an endemic area | TRYPANOSOMA CRUZI|ENFERMEDAD DE CHAGAS|ADN DE KINETOPLAST|DIAGNÓSTICO POR PCR |
Abstract. A large field study has been performed in the Cochabamba region of Bolivia with the aim of comparing the polymerase chain reaction (PCR) with other diagnostic methods for Chagas' disease. The amplification of Trypanosoma cruzi-specific kinetoplast DNA sequences in blood samples was compared with classical ser... | PCR-based diagnosis for Chagas' disease in Bolivian children living in an active transmission area : comparison with conventional serological and parasitological diagnosis | TRYPANOSOMA CRUZI|ENFERMEDAD DE CHAGAS|DIAGNÓSTICO PCR|DiIAGNÓSTICO SEROLÓGICO |
Admixture mapping (AM) is a promising method for the identification of genetic risk factors for complex traits and diseases showing prevalence differences among populations. Efficient application of this method requires the use of a genomewide panel of ancestry-informative markers (AIMs) to infer the population of origin... | A genomewide admixture mapping panel for hispanic/latino populations | MEZCLA GENÓMICA|POBLACIONES HISPANO/LATINO |
Esta investigación se propuso para estudiar el género como un factor afectivo importante que influye en el proceso de aprendizaje de lenguas extranjeras; profesores y estudiantes de EFL deben considerarlo, así como Oxford (1995) estableció.

Macedonio Fernández comenzó a escribir Museo de la novela de la Eterna en algún momento antes de 1929. La primera copia manuscrita de la novela data del 17 de junio de 1929, y fue realizada por Consuelo Bosch de Sáenz Valiente. Del manuscrito de puño y letra de Macedonio sólo se conservan pliegos sueltos y deteriorados... | Juego, amor y muerte en museo de la novela de la eterna de Macedonio Fernández | NOVELA|ESCRITURA DE UNA NOVELA |
Abastract. Pregnancy complications such as preeclampsia (PE) and intrauterine growth restriction (IUGR) are associated with reduced blood flow, contributing to placental and fetal hypoxia. Placental hypoxia is thought to cause altered production of angiogenic growth effectors (AGEs), reflected in the circulation of mot... | Evidence for extraplacental sources of circulating angiogenic growth effectors in human pregnancy | EMBARAZO HUMANO|PIGF|sFlt-1|VEGF PLATELETS|MONOCITOS |
Abtract. Background: The most well known reproductive consequence of residence at high altitude (HA .2700 m) is reduction in fetal growth. Reduced fetoplacental oxygenation is an underlying cause of pregnancy pathologies, including intrauterine growth restriction and preeclampsia, which are more common at HA. Therefore... | Hypoglycemia and the origin of hypoxia-induced reduction in human fetal growth | HIPOGLICEMIA|HIPOXIA-INDUCIDA|CRECIMIENTO FETAL |
ABSTRACT. Context: Placental hypoxia alters production of angiogenic growth factors (AGFs), thought to be causally involved in the development of the pregnancy-specific disease preeclampsia (PE). Consistent with this, the incidence of PE is increased at high altitude (HA, >2700m). Objective. We tested the hypotheses th... | Maternal and fetoplacental hypoxia do not alter circulating angiogenic growth factors : the emperor's got no clothes? | HIPOXIA FETOPLACENTAL|EMBARAZO |

Summary. Splanchnic blood flow was measured in fifteen young healthy subjects in La Paz, Bolivia (3.750 m.) at rest, during mild exercise and under oxygen (PIO₂ = 150 mmHg). The hematocrit of 9 of the subjects was normal for altitude whereas 6 has a low hematocrit as they were blood donors. Values did not differ betwee... | Les debits hepatosplanchnique et renal du resident d'altitude | ALTURA|RESIDENTES GRANDES ALTURAS|DÉBITOS HEPATOSPLANCHNIQUE |

ABSTRACT. We have studied linkage disequilibrium in natural populations of Trypanosoma cruzi, the agent of Chagas' disease, by analyzing (i) a set of 524 stocks from the whole geographical range of the parasite, characterized at four gene loci coding for enzymes; (ii) a subsample of 121 stocks characterized at 12 enzym... | Linkage disequilibrium in natural populations of Trypanosoma cruzi (Flagellate), the agent of Chagas'disease | TRYPANOSOMA CRUZI|ENFERMEDAD DE CHAGAS |
