Crystallization and preliminary X-ray diffraction analysis of a novel sphingomyelinase D from Loxosceles gaucho venom
(Acta Crystallographica Section F-structural Biology Communications, 2014-10-01) [Artigo]
Brown spider envenomation results in dermonecrosis, intravascular coagulation, haemolysis and renal failure, mainly owing to the action of sphingomyelinases D (SMases D), which catalyze the hydrolysis of sphingomyelin to ...
Crystallization and preliminary X-ray diffraction studies of an L-amino-acid oxidase from Lachesis muta venom
(Acta Crystallographica Section F-structural Biology Communications, 2014-11-01) [Artigo]
Snake-venom proteins form multi-component defence systems by the recruitment and rapid evolution of nonvenomous proteins and hence serve as model systems to understand the structural modifications that result in toxicity. ...
A coleta de corpus de aprendizes: questões qualitativas em uma pesquisa sobre a escrita de aprendizes de língua espanhola
(Estudos Linguísticos, 2014) [Artigo]
In this paper we discuss and present the first results gathered from the compilation of a learner corpus comprised of texts written by university students (Language, Literature and Translation Course). We made use of Corpus ...
Purification and biochemical characterization of an alkaline pectin lyase from Fusarium decemcellulare MTCC 2079 suitable for Crotolaria juncea fiber retting
(Journal Of Basic Microbiology, 2014-07-01) [Artigo]
An extracellular pectin lyase secreted by Fusarium decemcellulare MTCC 2079 under solid state fermentation condition has been purified to electrophoretic homogeniety by using ammonium sulfate fractionation, carboxymethyl ...
Energy decay for the linear Klein-Gordon equation and boundary control
(Journal of Mathematical Analysis and Applications, 2014-06-15) [Artigo]
In this work we study the asymptotic behavior of the solutions of the linear Klein Gordon equation in R-N, N >= 1. We prove that local energy of solutions to the Cauchy problem decays polynomially. Afterwards, we use the ...
Effects of maternal diabetes on male offspring: high cell proliferation and increased activity of MMP-2 in the ventral prostate
(Cell And Tissue Research, 2014-10-01) [Artigo]
This study presents a comprehensive view of the histological and functional status of the prostate of adult rat offspring of mothers subjected to gestational diabetes induced by alloxan. The ventral prostate of male adult ...
Ultrastructural characteristics of spermatogenesis in Pallas's mastiff bat, Molossus molossus (Chiroptera: Molossidae)
(Microscopy Research and Technique, 2012-07-01) [Artigo]
Despite the large number of species, their wide distribution, and unique reproductive characteristics, Neotropical bats have been poorly studied, and important aspects of the reproduction of these animals have not been ...
Rheology and fluid dynamics properties of sugarcane juice
(Biochemical Engineering Journal, 2011-02-15) [Artigo]
The sugarcane juice is a relatively low-cost agricultural resource, abundant in South Asia, Central America and Brazil, with vast applications in producing ethanol biofuel. In that way, a good knowledge of the rheological ...
Blood Sampling in Testudinidae and Chelidae.
(Herpetological Review, 2012-03-01) [Artigo]
Some remarks about Poincaré duality pairs
(JP Journal of Geometry and Topology, 2012-07-01) [Artigo]
Bieri-Eckmann  introduced the concept of relative cohomology for a group pair (G, S), where G is a group and S is a family of subgroups of G and, by using that theory, they introduced the concept of Poincaré duality ...
