Effect of the structure of commercial poly(ethylene oxide-b-propylene oxide) de...
Ramalho,João Batista V. S.; Lechuga,Fernanda C.; Lucas,Elizabete F.Water-in-crude oil emulsions are formed during petroleum production and asphaltenes play an important role in their stabilization. Demulsifiers are added to destabilize such emulsions,however the demulsification mechanism is not completely known. In this paper, the performances of commercial poly(ethylene oxide-b-propylene oxide) demulsifiers were studied using synthetic water-in-oil emulsions and model-systems...

Modulation of peritoneal macrophage activity by the saturation state of the fat...
Grando,F.C.C.; Felício,C.A.; Twardowschy,A.; Paula,F.M.; Batista,V.G.; Fernandes,L.C.; Curi,R.; Nishiyama,A.To determine the effects of saturated and unsaturated fatty acids in phosphatidylcholine (PC) on macrophage activity, peritoneal lavage cells were cultured in the presence of phosphatidylcholine rich in saturated or unsaturated fatty acids (sat PC and unsat PC, respectively), both used at concentrations of 32 and 64 µM. The treatment of peritoneal macrophages with 64 µM unsat PC increased the production of hydr...
Emoções e promoção da saúde
Batista, V.; Martins, D.; Martins, P.; Rodrigues, M.; Veiga-Branco, AugustaSer capaz de gerir os próprios afectos bem como as relações inter-sociais ao longo do tempo, são a proposta do estudo que a seguir se apresenta. Parte-se do pressuposto que uma das formas mais profundas de assegurar a Promoção da Saúde intra e interpessoal, é aprender a tornar-se emocionalmente competente (Veiga Branco, 2004; 2007). Ser emocionalmente competente é ser capaz de encontrar soluções, a partir de re...
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...
Comparing the performance of mobile agent systems: a study of benchmarking
Silva, L. M.; Soares, G.; Martins, P.; Batista, V.; Santos, L.In the past few years there has been an enthusiastic interest in mobile agent technology and several platforms have been developed. Some of them have only been used for research purposes while others have been deployed as commercial products. The community is now looking for applications where these platforms can be effectively used. Some comparisons about the functionality of some mobile agent systems have bee...
