CHEMICAL COMPOSITION, ANTIOXIDANT AND ANTIMICROBIAL PROPERTIES OF THREE ESSENTI...
Martins, M. Rosário; Tinoco, M. Teresa; Almeida, A. S.; Cruz-Morais, J.The present work reports on the evaluation of chemical composition and antioxidant and antimicrobial activities of essential oils of three aromatic herbs, growing wild in the south of Portugal, used in traditional food preparations: Foeniculum vulgare, Mentha spicata and Rosmarinus officinalis. The principal components of essential oils were anethole (41.2%) for F. vulgare, carvone (41.1%) for M. spicata and my...

Simulation of styrene polymerization reactors: kinetic and thermodynamic modeling
Almeida,A. S.; Wada,K.; Secchi,A. R.A mathematical model for the free radical polymerization of styrene is developed to predict the steady-state and dynamic behavior of a continuous process. Special emphasis is given for the kinetic and thermodynamic models, where the most sensitive parameters were estimated using data from an industrial plant. The thermodynamic model is based on a cubic equation of state and a mixing rule applied to the low-pres...
Low expression of antigen-presenting and costimulatory molecules by lung cells ...
Flores-Batista,V.C.S.; Boechat,N.; Lago,P.M.; Lazzarini,L.C.; Pessanha,L.R.; Almeida,A.S.; Mafort,T.T.; Kritski,A.L.; Ho,J.L.; Lapa-e-Silva,J.R.Costimulatory and antigen-presenting molecules are essential to the initiation of T cell immunity to mycobacteria. The present study analyzed by immunocytochemistry, using monoclonal antibodies and alkaline phosphatase-anti-alkaline phosphatase method, the frequency of costimulatory (CD86, CD40, CD40L, CD28, and CD152) and antigen-presenting (MHC class II and CD1) molecules expression on human lung cells recove...
