Bioactivity and Applications of Sulphated Polysaccharides from Marine Microalgae

Review Paper ; Marine microalgae have been used for a long time as food for humans, such as Arthrospira (formerly, Spirulina), and for animals in aquaculture. The biomass of these microalgae and the compounds they produce have been shown to possess several biological applications with numerous health benefits. The present review puts up-to-date the research on the biological activities and applications of poly...

Dois casos de Quérion por Trichophyton mentagrophytes

RESUMO Introdução: O Quérion é uma forma rara e inflamatória de tinea capitis causada por fungos dermatófitos. O diagnóstico é dificultado pela demora no exame cultural e possibilidade de várias etiologias no diagnóstico diferencial. O tratamento é prolongado e implica o recurso a antifúngicos sistémicos. Novos fármacos têm sido considerados após a descontinuação da griseofulvina em Portugal. Casos clínicos: Ap...

Polyphenol oxidase activity and colour changes of ‘Starking’ Apple cubes coated...

The objective was to study the effect of alginate coating on polyphenol oxidase (PPO) activity and colour of ‘Starking’ apple cubes during dehydration with hot air. Apple cubes were dehydrated at 20°C, 35°C or 40°C, with a parallel air-flow. Analysis of PPO activity, colour (L*, a*, b*) and dry matter were performed along the dehydration process at each temperature. All samples presented a peak in relative PPO ...

Chlorella vulgaris as Soil Amendment: influence of encapsulation and enrichment...

Several trials with five plant growth-promoting rhizobacteria (PGPR) and the chlorophyte Chlorella vulgaris were carried out in order to look for the consortia that could show the best interactions, giving rise to improved growth of mixed cultures. Pseudomonas putida, Serratia proteomaculans and Stenotrophomonas maltophilia were the chosen bacteria for the consortia with Chlorella, while the proportions of micr...

Comparison of some theoretical models for fittings of the temperature dependenc...

In this work we report on a comparison of some theoretical models usually used to fit the dependence on temperature of the fundamental energy gap of semiconductor materials. We used in our investigations the theoretical models of Viña, Pässler-p and Pässler-ρ to fit several sets of experimental data, available in the literature for the energy gap of GaAs in the temperature range from 12 to 974 K. Performin...

Utilização de técnicas de ultrasonografia em tempo real e de bioimpedância na d...

Foram utilizadas 20 coelhas das técnicas de ultrasonografia em tempo real e da bioimpedância A espessura da gordura escapular e após o abate foram determinad medida de gordura escapular está visceral a r = 0,85 para a perirenal; P também correlacionada (r = medidas de ultrasonografia e de resistência P < 0,01, respectivamente). Com a utilização da vivo, foi obtida por análise de 0,128PV; R 2 =0,865; P < 0,001 7...
