Induction of a gloverin-like antimicrobial polypeptide in the sugarcane borer D...
Silva,J.L.C.; Barbosa,J.F.; Bravo,J.P.; Souza,E.M. de; Huergo,L.F.; Pedrosa,F.O.; Esteves,E.; Daffre,S.; Fernandez,M.A.Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) is an important pest for Brazilian sugarcane. In the present study, we detected two distinct spots in hemolymph from septic injured larvae (HDs1 and HDs2), which are separated by 2DE gel electrophoresis. Both spots were subjected to in-gel tryptic digestion and MALDI-TOF/TOF analysis, which revealed the sequence VFGTLGSDDSGLFGK present in both HDs1...
Compilation of parameterized seismogenic sources in Iberia for the SHARE Europe...
Nemser, E.S.; García-Mayordomo, J.; Cabral, J.; Fonseca, J.; Martínez-Díaz, J.J.; Alfaro García, P.; Àlvarez Gómez, J.A.; Atakan, K.Abstract: SHARE (Seismic Hazard Harmonization in Europe) is an EC-funded project (FP7) that aims to evaluate European seismic hazards using an integrated, standardized approach. In the context of SHARE, we are compiling a fully-parameterized active fault database for Iberia and the nearby offshore region. The principal goal of this initiative is for fault sources in the Iberian region to be represented in SHARE...

Intrinsic bent DNA sites in the chromosomal replication origin of Xylella fasti...
Gimenes,F.; Gouveia,F. de S.; Fiorini,A.; Fernandez,M.A.The features of the nucleotide sequences in both replication and promoter regions have been investigated in many organisms. Intrinsically bent DNA sites associated with transcription have been described in several prokaryotic organisms. The aim of the present study was to investigate intrinsic bent DNA sites in the segment that holds the chromosomal replication origin, oriC, of Xylella fastidiosa 9a5c. Electrop...
The genus Huperzia (Lycopodiaceae) in the Azores and Madeira
Fernández Prieto, J.A.; Aguiar, Carlos; Dias, Eduardo; Fernández, M.A.; Homet, J.The taxonomy and nomenclature of the genus Huperzia Bernh. in the Azores and Madeira have been reviewed. Plants collected in the Azores and Madeira were characterized morphologically. The independence between two endemic species common to Madeira and the Azores Islands – Huperzia suberecta (Lowe) Tardieu and Huperzia dentata (Herter) Holub – is clearly shown. A clear-cut morphological separation between these t...
Occurrence of fumonisins B1 and B2 in broa, typical Portuguese maize bread
Lino, C. M.; Silva, L. J. G.; Pena, A.; Fernández, M.; Mañes, J.Fumonisin B1 (FB1) and fumonisin B2 (FB2) are mycotoxins mainly produced by Fusarium verticillioides, and Fusarium proliferatum, fungi species most commonly isolated from maize. The natural occurrence of FB1 and FB2 in broa, typical Portuguese maize bread, was evaluated in 30 samples. Twenty five were found positive with levels ranging from 142 to 550 [mu]g kg- 1. The limit established by the European regulatio...
Redes de empresas: proposta de uma tipologia para classificação aplicada na ind...
Hoffmann,Valmir Emil; Molina-Morales,F. Xavier; Martínez-Fernández,M. TeresaEste artigo se insere no contexto da atualização da temática das redes de empresas presente na Academia nestes tempos. Seu objetivo é propor uma tipologia para a classificação das redes de empresas. Esta tipologia deriva da literatura consultada e dos casos estudados, vinculando-a a quatro indicadores: direcionalidade, localização, formalização e poder. Para a ilustração da aplicação desta tipologia foram consi...
Posibilidades de la variabilidad genética de encinas y alcornoques en la conser...
Tapias, R.; Fernández, M.; Moreira, A. C.; Sánchez, E.; Cravador, A.Phytophthora cinnamomi Rands. (hongo patógeno del suelo) es el principal responsable del decaimiento de encinas y alcornoques en el Suroeste de la Península Ibérica. Este decaimiento es uno de los problemas ambientales más graves que amenaza la supervivencia y sostenibilidad, tanto ecológica como económica, de las formaciones de Quercus del sur peninsular. Este trabajo analiza la posibilidad del empleo de la va...
On the Low-Lying Excited States of sym-Triazine-Based Herbicides
Oliva, Josep M.; Azenha, M. Emilia D. G.; Burrows, Hugh D.; Coimbra, Rita; Melo, J. Serxio Seixas de; L., Moisés Canle; Fernández, M. IsabelWe report a joint computational and luminescence study on the low-lying excited states of sym-triazines, namely, 1,3,5-triazine (1) and the ubiquitous herbicides atrazine [6-chloro-N2-ethyl-N4-isopropyl-1,3,5-triazine-2,4-diamine (2)] and ametryn [6-methylthio-N2-ethyl-N4-isopropyl-1,3,5-triazine-2,4-diamine (3)]. Geometrical structures, energetics, and transition and state properties of 1 and 2 were computed a...
