Nanopartículas de quitosana e carragenanas: produção, caracterização e avaliaçã...
Chaves, Luciano de SousaThe nanoparticle drug delivery systems are a promising strategy to avoid the adverse conventional effects of cancer chemotherapy. In this work, nanoparticles produced by polyelectrolytic complexation of chitosan and κ, ι, λ-carrageenan were evalueted as a release system of 5-Fluorouracil. At first, the polyelectrolyte complexes were produced from several experimental conditions such as initial polyelectrolytes ...
Polissacarídeos de Alga Marinha Gracilaria birdiae (Plastino e Oliveira): Estru...
Chaves, Luciano de SousaSeaweeds beings are classified in the Kingdom Protist, predominantly aquatic and with great adaptive capacity. Found in all regions of the planet, algae play an important role ecological and economic, representing a great potential for biorrecursos. The red seaweed Gracilaria birdiae, submitted to aqueous extraction of polysaccharides, showedyield of 6.4% in the cold extraction (25-28 ºC) (Gb-f), and 56 % in th...
Anti-inflammatory effect of a sulphated polysaccharide fraction extracted from ...
Brito, Tarcisio Vieira de; Prudêncio, Rafael da Silva; Sales, Adriano Bezerra; Vieira Júnior, Francisco das Chagas; Candeira, Starley Jone NogueiraObjectives The aim of this study was to evaluate the anti-inflammatory effect of a sulphated polysaccharide fraction (PLS) extracted from the alga Hypnea musciformis and investigate the possible involvement of the nitric oxide (NO) pathway in this effect. Methods The anti-inflammatory activity of PLS was evaluated using inflammatory agents (carrageenan and dextran) to induce paw oedema and peritonitis in Swiss ...
