In this study, biocellulose (BC) membranes have been investigated as caffeine topical delivery systems, for the potential treatment of cellulite. BC-caffeine membranes were prepared by a simple approach and the permeation of caffeine through human epidermis, from BC or from conventional formulation systems (solution and gel), was compared in vitro to assess their therapeutic applicability. Diffusion studies wit...
Bacterial cellulose (BC) membranes were explored as novel nanostructured transdermal delivery systems for diclofenac sodium salt (a typical non-steroidal anti-inflammatory drug). Diclofenac sodium salt loaded BC membranes were prepared through a simple methodology, using glycerol as plasticizer, and characterized in terms of structure, morphology and swelling behavior. The membranes were very homogeneous, quite...
In this paper we propose a syntaxonomic scheme, according to the Code of Phytosociological Nomenclature for the vegetation of Portugal: continental and the Azores and Madeira archipelagos. The scheme encompasses 827 associations ( 4 communities), 245 alliances, 116 orders, and 64 vegetation classes. The 58 suballiances, 2 suborders and 4 classes, are also mentioned, as auxilliary ranks. For the higher syntaxa d...

Neste trabalho apresenta-se um catálogo de todos os sintaxa, de associação até classe presentes em Portugal continental, Madeira, Açores e Selvagens. Foram reconhecidas 755 associações, 236 alianças, 51 subalianças, 114 ordens, 2 subordens, 4 subclasses e 64 classes. As ilhas Desertas, Selvagens e o Arquipélago dos Açores são os territórios nacionais com menos informação, não havendo qualquer sintáxone descrito...
Resumo: A veia cava inferior pré-ureteral é uma anomalia congénita rara. Em 25% dos casos existem outras anomalias congénitas associadas, sobretudo do sistema genito-urinário e musculoesquelético. Apesar de se tratar de uma patologia congénita, os sintomas surgem habitualmente na 3ª ou 4ª década de vida, resultantes de um efeito compressivo exercido pela veia cava inferior sobre o ureter, com consequente hidron...
