Leites e Fórmulas Infantis: Uma Visão Actualizada da Realidade em Portugal
Rego, Carla; Ribeiro, Laura; Guerra, AntónioO leite materno constitui o alimento ideal nos primeiros meses de vida, sendo a sua composição um guia importante para a elaboração das fórmulas suas substitutas, muito embora a grosseira similaridade não seja, por si só, um indicador de segurança nutricional para os lactentes. No entanto, quando não é possível o aleitamento materno, dispomos no mercado português de uma variada oferta de leites e fórmulas.Todos...
Estado de Nutrição, Hábitos Alimentares e Dispêndio Energético em Crianças com ...
Guerra, Paula; Almeida, João; Rego, Carla; Nunes, Teresa; G. Vaz, Luisa; Silva, Diana; Lourenço, Susana; Ribeiro, Laura; M. Guerra, António J.O presente trabalho tem como objectivo avaliar o estado de nutrição, a composição corporal e a função respiratória de um grupo de crianças com fibrose quística sem evidência clínica ou laboratorial de infecção recente, assim como o de conhecer os seus hábitos alimentares e determinar o valor do dispêndio energético de repouso medido por calorimetria indirecta e o avaliado pelas equações de Schofield, da Organiz...

Trypanosoma (Duttonella) vivax: its biology, epidemiology, pathogenesis, and in...
Osório,Ana Luiza Alves Rosa; Madruga,Claudio Roberto; Desquesnes,Marc; Soares,Cleber Oliveira; Ribeiro,Laura Raquel RiosThe biology, epidemiology, pathogenesis, diagnostic techniques, and history of the introduction of Trypanosoma (Duttonella) vivax in the New World are reviewed. The two main immunological responses of trypanosome-infected animals - antibody production and immunodepression - are discussed in the context of how these responses play a role in disease tolerance or susceptibility. Isolation and purification of T. vi...
Characterization of rat heart alkaline phosphatase isoenzymes and modulation of...
Mota, A.; Silva, P.; Neves, Delminda; Lemos, C.; Calhau, Conceição; Torres, Duarte; Martel, Fátima; Fraga, H.; Ribeiro, Laura; Alçada, Manuel NunoAlkaline phosphatase (ALP) is important in calcification and its expression seems to be associated with the inflammatory process. We investigated the in vitro acute effects of compounds used for the prevention or treatment of cardiovascular diseases on total ALP activity from male Wistar rat heart homogenate. ALP activity was determined by quantifying, at 410 nm, the pnitrophenol released from p-nitrophenylphos...
Cyclodextrin multicomponent complexation and controlled release delivery strate...
Ribeiro, Laura S. S.; Falcão, Amílcar C.; Patrício, João A. B.; Ferreira, Domingos C.; Veiga, Francisco J. B.In the present work, to maintain a suitable blood level of vinpocetine (VP) for a long period of time, VP-cyclodextrin-tartaric acid multicomponent complexes were prepared and formulated in hydroxypropylmethylcellulose matrix tablets. In vitro and in vivo performances of these formulations were investigated over a VP immediate release dosage form. Solubility studies were performed to evaluate the drug pH solubi...
Evaluation of host-guest complex formation between a benzimidazolic derivative ...
Figueiras, Ana; Ribeiro, Laura; Torres-Labandeira, J.; Veiga, Francisco J.Abstract Interactions between a benzimidazolic derivative, omeprazole (OME), beta-cyclodextrin (ßCD) and a chemically modified ßCD, methyl-beta-cyclodextrin (MßCD) were investigated in aqueous solution by UV-VIS spectroscopy and in solid state by differential scanning calorimetry (DSC). Phase solubility studies were used to evaluate the complexation in aqueous solution. The two solubility diagrams obtained wer...
Preparation and physicochemical characterization of omeprazole:methyl-beta-cycl...
Figueiras, Ana; Ribeiro, Laura; Vieira, M.; Veiga, FranciscoAbstract In this work, we illustrate the usefulness of cyclodextrins, namely, methyl-ß-cyclodextrin (MßCD), an amorphous, methylated derivative of the natural ß-cyclodextrin (ßCD), as a tool to form an inclusion complex with omeprazole (OME), a poorly water soluble drug. Solid binary systems between OME and MßCD were prepared experimentally in a stoichiometry 1:1 by different techniques (physical mixing, knead...
