Aclimatação ex vitro de pereira (Pyrus communis L.) microporopagada. Estudo de ...

A pereira (Pyrus communis L.) é uma espécie frutícola de elevada importância na fruticultura Portuguesa. A produção nacional em 2005-6 foi de 129 mil toneladas para uma área cultivada de 12 mil hectares. Em 2010-11 a produção ascendeu às 220 mil toneladas. A cultivar “Rocha” é das mais importantes em termos de exportação com um volume de vendas em 2005 de 26 milhões de euros para 45 mil toneladas de pêra corres...

Seleção de genótipos de cana-de-açúcar para acúmulo de protoporfirina ix com us...

O objetivo do presente trabalho foi selecionar genótipos de cana-de-açúcar por meio de inibidores da PROTOX e antioxidantes para indução do acúmulo de protoporfirina IX (PROTO IX) e/ou de seus precursores em plantas. Esses compostos podem ser utilizados como agentes sensibilizantes em terapia fotodinâmica (TFD), os quais possibilitam uma fonte de baixo custo para o tratamento de neoplasias e carcinomas. O exper...

Chemical tracers of Lusitanian amphorae kilns from the Tagus estuary (Portugal)

In this paper, the characterization of Roman amphorae from the Porto dos Cacos (PC) and Quinta do Rouxinol (QR) workshops, in the Tagus estuary, dating to a period between the 1st and 5th century AD was carried out on the basis of instrumental neutron activation analysis data on 260 amphorae fragments, together with mineralogical compositional studies obtained by X-ray diffraction. Special attention was devoted...

Interaction study of moxifloxacin with Cu(II) ion using square-wave voltammetry...

This work presents an electroanalytical method for the determination of moxifloxacin (MOXI) in tablets by its interaction with Cu(II) ion and subsequent electrochemical reduction at hanging mercury drop electrode (HMDE). A well-defined reduction peak at -0.21 V vs. Ag/AgCl in Phosphate buffer 0.04 mol L-1 pH 8.0 was observed for the complex reduction MOXI-Cu(II), using square-wave voltammetry (SWV). Using a 10 ...
