A monitorização do consumo de antimicrobianos é um instrumento de interesse indiscutível e tem merecido uma atenção particular nos últimos anos, devido às crescentes preocupações com a emergência de estirpes microbianas multi-resistentes. Os objectivos do presente estudo consistiram, por um lado, na monitorização do consumo e na avaliação do impacto económico da prescrição hospitalar de antimicrobianos, em serv...
The effect of polysaccharide content on the stability of an oil-in-water emulsion (20% oil, droplet diameter 6.5 mum, pH = 7) containing soy protein (5 mg/ml) as the emulsifying agent was studied. Flocculation occurs by addition of two depletion flocculants: xanthan (0.01- 0.4%) and lambda-carrageenan (0.001- 2%). We report that in both cases the onset of flocculation occurs below the overlap polymer concentrat...
Salivary cortisol is an index of plasma free cortisol and is obtained by a noninvasive procedure. We have been using salivary cortisol as a tool for physiological and diagnostic studies, among them the emergence of circadian rhythm in preterm and term infants. The salivary cortisol circadian rhythm in term and premature infants was established between 8 and 12 postnatal weeks. In the preterm infants the emergen...
A faunistic survey of the species of Callinectes Stimpson, 1871 carried out in the coastal and estuarine regions of the State of Rio Grande do Norte yielded five species: C. bocourti A. Milne Edwards, 1879; C. danae Smith, 1869; C. exasperatus (Gerstaecker, 1856); C. larvatus Ordway, 1863 and C. ornatus Ordway, 1863.
