The present work documents the first example of an enzymecatalyzed -elimination of a thioether from a sulfonium cysteine S-conjugate. -(S-Tetrahydrothiophenium)-L-alanine (THT-A) is the cysteine S-conjugate of busulfan. THT-A slowly undergoes a nonenzymatic -elimination reaction at pH 7.4 and 37°C to yield tetrahydrothiophene, pyruvate, and ammonia. This reaction is accelerated by 1) rat liver,...

Conhecer a distribuição e o padrão espacial de espécies dentro uma comunidade vegetal é imprescindível para planejamento estratégias conservação estabelecer medidas manejo sustentável em formações florestais, sobretudo áreas Caatinga. Nesse sentido, objetivo do estudo foi analisar estrutura Pilosocereus pachycladus F. Ritter subsp. pernambucoensis (F. Ritter) populações naturais Caatinga Brejo ...

In this paper we explain how we created a labelled corpus in English for a Named Entity Recognition (NER) task from multi-source and multi-domain data, for an industrial partner. We explain the specificities of this corpus with examples and describe some baseline experiments. We present some results of domain adaptation on this corpus using a labelled Twitter corpus (Ritter et al., 2011). We te...

In this work, the performance of graphene nanosheets (GNs) and graphene oxide (GO) nanosheets, as a support for palladium nanoparticles (PdNPs) toward oxygen reduction reaction (ORR), was studied. The graphene nanosheets were functionalized by a new and simple method. The PdNPs were synthesized on a glassy carbon electrode (GCE) modified with GNs or GO via a potentiostatic method; without using...
