Fracturas-Avulsão da Tuberosidade Anterior da Tíbia em Adolescentes
Batista, N; Sarmento, M; Thuesing, M; Tavares, D; Cassiano Neves, MAs fracturas-avulsão da tuberosidade anterior da tibia (TAT) são raras no doente esqueleticamente imaturo. A prevalência de doença de Osgood-Schlatter prévia à fractura é variável de estudo para estudo, parecendo haver apenas uma correlação associativa e não causal. Os autores apresentam a revisão de 7 adolescentes com fracturas/avulsão da TAT tratados cirurgicamente. São abordados os aspectos relativos à class...
Influence of intrinsic factors on conventional wine protein stability tests
Sarmento, M.R.; Oliveira, J.C.; Slatner, M.; Boulton, R.B.The influence of intrinsic factors on the results of ethanol, tannin and heat tests, routinely used to assess wine protein stability, was studied. Experiments were performed on 23 Portuguese and Austrian wines. The factors considered were total protein content, pH, ethanol content and the amount of several relevant cations (calcium, iron, copper, sodium and potassium). The protein pro®les were analysed by HPLC ...
Kinetics of the adsorption of bovine serum albumin contained in a model wine so...
Sarmento, M.R.; Oliveira, J.C.; M. Slatner, M.; Boulton, R.B.Adsorption of wine proteins is an essential step in the production of white and rosé wines. In order to develop environmentally friendly adsorption processes, non-swelling adsorbents are required. The performance of selected non-swelling ion-exchange resins (Macro-Prep™ 50S and Streamline® SP) was studied by describing the process kinetics of the adsorption of BSA in a model wine solution. The process was assum...
