This paper examines the association between serum protein levels and infection with Trypanosoma cruzi in a region of Central Brazil. 148 people 6 to 78 years of age, were included in this study. There were no statistically significant difference in albumin levels between those with positive T. cruzi
OBJECTIVE
Microvascular abnormalities have been postulated in the pathogenesis of chagasic cardiomyopathy. The objective of this study was to evaluate the relationship between coronary microcirculation and systolic function impairment in baboons with Chagas disease using myocardial contrast
Even though trifluralin (alpha,alpha,alpha-2,6-dinitro-N-N-dipropyl-p-toluidine) is effective for the treatment of experimental Chagas disease, more preclinical toxicity studies need to be performed. Cell toxicity of trifluralin was studied in Hep-G2 and Vero C76 cells treated with 50 and 150 microM
Copper(II) complexes with the first-generation quinolone antibacterial agent norfloxacin containing a nitrogen donor heterocyclic ligand 2,2'-bipyridine (bipy) or 1,10-phenanthroline (phen) were prepared and characterized by IR, EPR spectra, molar conductivity, and elemental analyses. The
Zn(II) complexes with norfloxacin (NOR) in the absence or in the presence of 1,10-phenanthroline (phen) were obtained and characterized. In both complexes, the ligand NOR was coordinated through a keto and a carboxyl oxygen. Tetrahedral and octahedral geometries were proposed for [ZnCl2(NOR)]·H2O
In the search for new metal-based drugs for the treatment of Chagas disease, the most widespread Latin American parasitic disease, novel complexes of the bioactive ligand risedronate (Ris, (1-hydroxy-1-phosphono-2-pyridin-3-yl-ethyl)phosphonate), [M(II)(Ris)(2)]·4H(2)O, where M═Cu, Co, Mn and Ni,
Infection with Trypanosoma cruzi can cause chronic Chagas' disease manifestations (cardiac, gastrointestinal), although most persons with chronic infection have no ill effects (indeterminate form). Cell-mediated immunity (CMI) responses are believed to be intrinsically important in the containment
A novel immunodiagnosis reagent for detecting the Chagas Disease was developed, by chemical coupling of antigen Ag36 of Trypanosoma cruzi onto two (carboxylated and core-shell) latexes. The coupling reactions involved the use of a carbodiimide intermediate. Bovine serum albumin (BSA) was used as a
BACKGROUND
Chagas disease is highly prevalent in Latin America, and vector control is the most effective control strategy to date. We have previously shown that liquid chromatography tandem mass spectrometry (LC-MS/MS) is a valuable tool for identifying triatomine vector blood meals.
OBJECTIVE
The
Chagas disease (CD) is a parasitic zoonosis endemic in most mainland countries of Central and South America affecting nearly 10 million people, with 100 million people at high risk of contracting the disease. Treatment is only effective if received at the early stages of the disease. Only two drugs
Chagas disease (ChD), caused by the hemoflagellate parasite Trypanosoma cruzi, affects six to seven million people in Latin America. Lately, it has become an emerging public health concern in nonendemic regions such as North America and Europe. There is no prophylactic or therapeutic vaccine
The protozoan parasite, Trypanosoma cruzi, the etiologic agent of Chagas disease (ChD), has a cell surface covered by immunogenic glycoconjugates. One of the immunodominant glycotopes, the trisaccharide Galα(1,3)Galβ(1,4)GlcNAcα, is expressed on glycosylphosphatidylinositol-anchored mucins of the
The spleens of mice infected with Trypanosoma cruzi were tested for their contents of cells producing IgM, IgG1, IgG2a, IgG2b, and IgG3 specific for the trinitrophenyl hapten after immunization with trinitrophenyl-Ficoll and trinitrophenyl-bovine serum albumin at various times during the acute and
Germfree (GF) and conventional (CV) mice were fed on diets containing 4.4, 13.2 or 26.4% of protein (weight/weight). CV mice fed on low protein diet did not gain weight during four weeks, whereas the protein deficient diet did not affect the growth of GF mice. After four weeks on these diets, the
OBJECTIVE
To evaluate the survival of patients with heart failure submitted to cardiac transplantation screening as well as identify poor prognostic factors using a risk score to identify patients with higher death risk.
METHODS
330 male and female patients aged 12 to 74 years old, referred for
