Gases en sangre
(s.n., 1986)La hematosis constituye una importante etapa fisiológica en el curso de la cual se efectúan los intercambios gaseosos entre la sangre que llega por los capilares pulmonares y el medio gaseoso intra-alveolar, es decir la ... -
Gender differentiation of the chemoreflex during growth at high altitude : functional and nerurochemical studies
(Am J Physiol Regulatory Integrative Comp Physiol, 2000)The effect of chronic hypoxia on gender differences in physiology and neurochemistry of chemosensory pathways was studied in prepubertal and adult rats living at sea level (SL; Lyon, France) or at high altitude (HA; La ... -
General classification of the isoenzymic strains of Trypanosoma (Schizotrypanum) cruzi and comparison with T. (S.) C. Marinkellei and T. (Herpetosoma) rangeli
(Ann. Soc. Belge Med. Trop., 1984)Summary. Thirteen laboratory reference stocks of Trypanosoma (Schizottypanum) cruzi were classified according to genetic distance by enzyme analysis of 14 loci. Three principal isoenzymic strains were recognized together ... -
General conclusions from the study on 10- to 12-year-old Bolivian boys and suggestions for future research
(Int. J. Sports Med., 1994)The effects of resident altitude and socioeconomic status on the physical health and fitness were investigated in 10- and 11-year-old prepubertal boys living at two altitudes (high altitude: ca. 4000 m and low altitude: ... -
Genetic structure of Triatoma sordida (Hemiptera: Reduviidae) domestic populations from Bolivia : application on control interventions
(Mem. Inst. Oswaldo Cruz, 1999)The genetic population of Triatoma sordida group 1, a secondary vector of Chagas disease in Bolivia, was studied by multi-locus enzyme electrophoresis. A total of 253 nymphal and adult specimens collected from seven ... -
Genetic variability and geographic differentiation among three species of Triatomine bugs (Himiptera- Reduviidae)
(Am. J. Trop Med. Hyg., 1997)Abstract. Three species of triatomine bugs, Triatoma sordida, T. guasayana, and T. patagonica, were examined by cytogenetic (C-banded karyotypes and male meiotic process) and isoenzymatic studies. These three species, ... -
Genetic variability and microdistribution of Triatoma infestans genotypes and Trypanosoma cruzi clones in Arequipa región (Peru)
(Mem. Inst. Oswaldo Cruz, 1997)The genetic variability of Triatoma infestans and Trypanosoma cruzi populations was studied by isoenzyme analysis in two distinct areas of Arequipa province (Peru); one, Santa Rita de Siguas, being an endemic area for ... -
Genetic variations in the TP53 pathway in native americans strongly suggest adaptation to the high altitudes of the andes
(PLOS One, 2015-09-18)Abstract. The diversity of the five single nucleotide polymorphisms located in genes of the TP53 pathway (TP53, rs1042522; MDM2, rs2279744; MDM4, rs1563828; USP7, rs1529916; and LIF, rs929271) were studied in a total of ... -
Genética de poblaciones de triatomineos en relación a las estrategias de control de insectos vectores
(Bol. Soc. Zool. Uruguay, 1995)The causative agent of Chagas disease infects more than 16 millions persons in Latin America; the resulting human chronic pathology is responsible of an important economic loss. The authors first analyze the main features ... -
Genética formal, caracteres mono y multifactoriales, heredabilidad
(Universidad de los Andes, 1997)Se han desarrollado algunas técnicas estadísticas que permiten establecer el número y el tipo de genes involucrados en la expresión de un rasgo fenotípico determinado. Es así como examinando la frecuencia de individuos de ... -
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 ... -
