Impairment of monocytic function during Trypanosoma cruzi infection
(Clinical and Diagnostic Laboratory Immunology, 1994-11)
During acute infection, Trypanosoma cruzi, the etiologic agent of Chagas' disease, causes immunosuppression by mechanisms that are not fully delineated. Since mononuclear phagocytes are major target cells in trypanosomiasis, ...
In vitro lymphocyte-differentiating effects of thymulin (Zn-FTS) on lymphocyte subpopulations of severely malnourished chidren
(Am J Clin Nutr, 1994)
ABSTRACT. This work investigates how thymic dysfunction contributes to the depression of cell-mediated immunity in protein-energy malnutrition (PEM). In Bolivian children hospitalized for severe PEM, the size of the thymus ...
High correlation between Chagas' disease serology and PCR-based detection of Trypanosoma cruzi kinetoplast DNA in Bolivian children living in an endemic area
(FEMS Microbiology Letters, 1994)
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 ...
Detection of sylvatic dark morphs of Triatoma infestans in the Bolivian Chaco
(Mem. Inst. Oswaldo Cruz, 1997)
Triatoma infestans, the most important vector of Chagas disease in the southern part of Latin America, is considered to originate from the Cochabamba valley in Bolivia because this is the only region where true sylvatic ...
Characterization of T cell clones from Chagasic patients : predominance of CD8 surface phenotype in clones from patients with pathology
(Mem. Inst. Oswaldo Cruz, 1995)
ABSTRACT.
Human Chagas' disease, caused by the protozoan Trypanosoma cruzi, is associated with pathological processes whose mechanisms are not known. To address this question, T cell lines were developed from chronic ...
Weekly iron supplementation is as effective as 5 day per week iron supplementation in Bolivian school children living at high altitude
(European Journal of Clinical Nutrition, 1997)
Objective: To compare the efficacy of a daily and a weekly iron supplementation on the hematological status of anemic children living at high altitude.
Design: Double blind iron supplementation trial including a placebo ...
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 ...
Immune response to Trypanosoma cruzi shed acute phase antigen in children from an endemic area for Chagas'disease in Bolivia
(Mem. Inst. Oswaldo Cruz, 1997)
A field study of the immune response to the shed acute phase antigen (SAPA) of Trypanosoma cruzi was carried out in the locality of Mizque, Cochabamba department, Bolivia. Schoolchildren (266), with an average of 8.6 ± 3.6 ...
Parámetros normales de la función diastólica, en sujetos nativos de altura : evaluación mediante ecocardiografía-Doppler
(Revista Médica, 1997)
Resumen. La ecocardiografía doppler se ha venido empleando para evaluar la función diastólica ventricular en forma no invasiva. El objetivo del presente estudio es conocer los valores de referencia de los principales ...
