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. ...
SPASMOGENIC NONCHOLINERGIC ACTIVITY OF A DIGESTIVE GLAND HOMOGENATE OF THE AMPHIBIAN SNAIL POMACEA-LINEATA SPIX-1827
(Brazilian Journal of Medical and Biological Research, 1991-01-01) [Artigo]
The digestive gland of Pomacea lineata, a prosobranch gastropod mollusc inhabiting both fresh water and land, does not contain cholinomimetic compounds as do the glands of species of Aplysia, marine opisthobranch gastropods, ...
HYBRIDIZATION AMONG 3 SPECIES OF ANDROPOGON (POACEAE, ANDROPOGONEAE) IN SOUTHERN BRAZIL
(Bulletin of the Torrey Botanical Club, 1987-10-01) [Artigo]
Analysis of CDKN1A polymorphisms: markers of cancer susceptibility?
(Cancer Genetics and Cytogenetics, 2003-04-15) [Artigo]
The CDKN1A (TP21)(2) gene encodes a 21-kD protein that is a critical downstream mediator of wild-type TP53 and an important regulator of the cell cycle. Failure in the function of this gene would be expected to result in ...
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 ...
Evaluation of fitness components in strains of Drosophila mulleri carrying different genotypes for an esterase
(Cytobios, 2001-01-01) [Artigo]
Several fitness components in strains of Drosophila mulleri carrying the slow or the fast alleles for the major beta esterase (esterase-4) found in this species, as well as in heterozygous flies in which the slow or fast ...
RELEASE OF VARIABILITY THROUGH RECOMBINATION OF DROSOPHILA-MELANOGASTER X-CHROMOSOMES, WITH SEX-LIMITED EFFECT
(Revista Brasileira de Genética, 1981-01-01) [Artigo]
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 ...
