ABSTRACT The clinical course of Chagas' disease varies widely among different patients and geographic regions. For reasons that are not completely understood but involve host and parasite factors, some patients never develop the disease while others present cardiac and/or gastrointestinal symptoms. Many studies have been conducted in order to correlate the genetic variability of the parasites with the clinical forms of the disease, but no conclusive data have been obtained. Our research aims at ...

Due to the scarcity of evidence of sexuality in Trypanosoma cruzi, the causative agent of Chagas disease, it has been general accepted that the parasite reproduction is essentially clonal with infrequent genetic recombination. This assumption is mainly supported by indirect evidence, such as Hardy-Weinberg imbalances, linkage disequilibrium and a strong correlation between independent sets of genetic markers of T. cruzi populations. However, because the analyzed populations are usually isolated ...

This paper presents a comparison between a multiple response function (MR) proposed for optimization of analytical strategies involving multi-element determinations with the desirability function D, which was proposed by Derringer and Suich in 1980. The MR function is established by the average of the sum of the normalized responses for each analyte considering the highest value of these. This comparison was performed during the optimization of an spectrometer for quantification of six elements using ...

The synthesis of a novel series of 5,5′-sulfonamide thioindigo derivatives, including a new synthetic methodology (via microwave assisted synthesis), together with a comprehensive electronic spectral and photophysical characterization is described. The study made in solution, as a function of the solvent polarity, showed -rationalized by TDDFT calculations- that in nonpolar solvents the high efficiency of the radiative deactivation channel (50% in dioxane and 70% in benzene) is due to an S1 (of π,π* ...

The effect of the alkyl chain length on the spectral (including color) and photophysical properties of the compounds was explored. This was done with solvents of different viscosities and polarities (dielectric constants). From time-resolved fluorescence and femtosecond-transient ...

This paper discusses the use of matching-to-sample as a procedure to investigate symbolic behavior acquisition when studying the evolution of language. It is argued that generalized identity and stimulus classes formed after learning arbitrary interconnected conditional stimulus relationships may be the result of basic pre-symbolic processes. Such aspects may thus provide relevant information for interdisciplinary research on symbolic behavior and language evolution. An individualized approach when ...
