CYP2C19*2 and prognosis after an acute coronary syndrome: Insights from a Portu...
Teixeira, R; Monteiro, P; Marques, G; Pego, J; Lourenço, M; Tavares, C; Reboredo, A; Monteiro, S; Gonçalves, F; Ferreira, MJ; Freitas, M; Ribeiro, GBACKGROUND: Clopidogrel requires oxidation dependent on the cytochrome P450 enzyme 2C19 (CYP2C19) to form its active metabolite. The importance of loss-of-function alleles (particularly CYP2C19*2, 681G>A) in poor platelet response to clopidogrel is well recognized. OBJECTIVE: To investigate the prevalence and prognostic impact of the CYP2C19*2 allele in a local acute coronary syndrome (ACS) population. METHOD...
Effects of the dietary incorporation of untreated and white-rot fungi (Ganoderm...
Ribeiro, Luis; Pinheiro, Victor; Outor-Monteiro, Divanildo; Mourão, José Luís; Bezerra, R.M.F; Dias, A.A.; Bennett, R.N; Marques, G.; Rodrigues, M.A.The aim of this study was to evaluate the effects of the level of inclusion of olive leaves and its pre-treatment with Ganoderma resinaceum Boud on growth performance, nutrient digestibilities and caecal fermentation. A total of 48 rabbits were kept in individual cages and divided in 4 groups of 12 animals. Animals were fed ad libitum with one of four diets based on a basal feed for growing rabbits – Control di...

Two-photon absorption processes in semiconductor quantum dots
López Gondar,J.; Cipolatti,R.; Marques,G. E.The two-photon absorption process is a nonlinear phenomenon that shows very low optical efficiency in bulk semiconductors. For this reason the detection of these processes becomes very difficult from the experimental point of view. Nevertheless, when dealing with semiconductor QD's with few nanometer radii, these transitions are enhanced and the detection is possible. In this contribution we present analytical ...
O Carvalho Negral
Carvalho, J; Santos, J; Reimão, D; Gallardo, J; Alves, P; Grosso-Silva, J; Santos, T; Pinto, A; Marques, G; Martins, L; Carvalheira, M; Santos, JOs carvalhais autóctones são um património natural de muito valor. Desempenham importantes funções de conservação do solo e da água, da biodiversidade, da paisagem natural, e na melhoria do edafo-clima, para além de fornecerem importantes recursos lenhosos e não-lenhosos para diversos fins. Paralelamente com a conservação e protecção do ambiente e da natureza, contribuem para uma satisfação sócio-económica das ...
Electron spin-phonon relaxation in quantum dots
Alcalde,A. M.; Marques,G. E.We calculate the spin relaxation rates in parabolic quantum dots due to the phonon modulation of the spin-orbit interaction in presence of an external magnetic field. Both, deformation potential (DP) and piezoelectric (PE) electron-phonon couplings are included in the Pavlov-Firsov spin-phonon Hamiltonian. We demonstrate that the spin relaxation rates are particularly sensitive with the Landé g-factor, and that...
Electron-acoustic phonon scattering rates in spherical quantum dots: contributi...
Alcalde,A. M.; Marques,G. E.; Weber,G.; Reinecke,T. L.The electronacoustic-phonon scattering process in spherical II-VI quantum dots is discussed. The quantized acoustic modes are described in terms of the Lamb's classical theory. We considered two mechanism for the interaction between electrons and acoustic modes: microscopic deformation potential, and macroscopic acoustic deformation, also called the ripple mechanism. We also discuss the in uence of the glass ma...
nipi delta-doping superlattices for amplitude modulation
Tribuzy,C. V.-B.; Landi,S. M.; Pires,M. P.; Butendeich,R.; Souza,P. L.; Bittencourt,A. C.; Marques,G. E.; Henriques,A. B.GaAs/AlGaAs multiple quantum well structures containing an nipi delta-doping superlattice, where the n-type doping is inserted in the quantum wells and the p-type in the barriers, have been studied in detail to evaluate their potential for use in the fabrication of amplitude modulators. It is shown that C is an adequate p-type dopant for such structures, however, little exibility is found in the growth conditio...
