Associação entre maturação esquelética, estatuto sócio-económico e índice de ma...

Introdução: A associação entre maturação esquelética, estatuto sócio-económico e índice de massa corporal foi investigada numa amostra longitudinal mista de crianças e adolescentes portugueses (251 raparigas e 256 rapazes), dos 7 aos 18 anos de idade.Métodos: A maturação esquelética foi estimada a partir das radiografias da mão e do punho esquerdos, usando o método Tanner-Whitehouse II. O estatuto sócio-económi...

Tiroidite de Quervain: Caso clínico

Benthic meiofauna as indicator of ecological changes in estuarine ecosystems: T...

Estuarine meiofauna communities have been only recently considered to be good indicators of ecological quality, exhibiting several advantages over macrofauna, such as their small size, high abundance, rapid generation times and absence of a planktonic phase. In estuaries we must account not only for a great natural variability along the estuarine gradient (e.g. sediment type and dynamics, oxygen availability, t...

New sustained release of Zidovudine Matrix tablets − cytotoxicity toward Caco-2...

Objective: The aim of this study was to adjust the zidovudine (AZT) release from solid tablets to an ideal profile, by developing matrices comprising swellable polymers with nonswellable ones. Methods: Directly compressed matrices comprised different ratios of hydroxypropylmethylcellulose K15M and K100M, ethylcellulose, and methacrylic acid (Eudragit® RS PO and Eudragit® RL PO) were prepared. Technological char...

Doença de Mãos-Pés-Boca no Adulto - Um Caso Clínico

A doença de mãos-pés-boca é uma infecção viral, mais frequentemente causada pelos vírus coxsackie A16 e enterovírus 71, que afecta preferencialmente crianças com idade inferior a 10 anos. Geralmente é uma doença benigna, caracterizada por febre e vesículas na boca e extremidades distais, mas também pode associar-se a complicações mais graves com meningoencefalite ou miocardite. Os autores reportam um caso de DM...

An investigation of the potential application of chitosan/aloe-based membranes ...

A significant number of therapeutics derived from natural polymers and plants have been developed to replace or to be used in conjunction with existing dressing products. The use of the therapeutic properties of aloe vera could be very useful in the creation of active wound dressing materials. The present work was undertaken to examine issues concerning structural features, topography, enzymatic degradation beh...

Functional cell microcarriers : a new platform for cell separation and expansion

Publicado em "Journal of Tissue Engineering and Regenerative Medicine", vol. 7, supp. 1 (2013) ; The success of many stem cell applications in the biomedical field is highly dependent on the development of separation techniques for isolation and purification of cells with a very high yield and purity. Despite all the achievements made in the field over the past several years, new systems for effective cell sep...

Combination of aloe vera improves the biological performance of chitosan membra...

Publicado em "Journal of Tissue Engineering and Regenerative Medicine", vol. 7, suppl. 1 (2013) ; In the last years, aloe vera (AV), a tropical plant belonging to theliliaceaefamily, has gained popularity for medical, cosmetic and nutritional purposes. Commercially, AV appears in food supplements, as additive to drinks, coating fruits, moisturizer, and healing agent in cosmetic products, among others uses. The...

Lesões das Extremidades

Banca Prática inserida no Workshop Trauma em Situações Especiais realizado no dia 8 de Dezembro de 2012 no CHLisboa Central que aborda a avaliação primária e secundária das lesões das extremidades bem como casos particulares nomeadamente a amputação traumática e o uso de garrote e as queimaduras dos membros. Na mesma prática demonstrou-se a aplicação do garrote CAT (R) e do "Cling Film".

The use of ionic liquids in the processing of chitosan/silk hydrogels for biome...

Natural polymers are adequate renewable resources for the processability of well-defined architectures for several applications. Combinations of polysaccharides and proteins may mimic the naturally occurring environment of certain tissues. The main goal of this work renders the application of green chemistry principles, namely the use of ionic liquids (ILs) and biorenewable sources, such as chitosan (CHT) and s...
