Excitotoxic lesions in the central nucleus of the amygdala attenuate stress-ind...
Silva, Ana Paula Ventura; Melo, António; Ferreira, Ana Catarina; Carvalho, M. M.; Campos, Filipa L.; Sousa, Nuno; Pêgo, José M.The extended amygdala, composed by the amygdaloid nuclei and the bed nucleus of the stria terminalis (BNST), plays a critical role in anxiety behavior. In particular, the link between the central nucleus of the amygdala (CeA) and the BNST seems to be critical to the formation of anxiety-like behavior. Chronic unpredictable stress (CUS) exposure is recognized as a validated animal model of anxiety and is known t...
Mesenchymal stem cells secretome : a new paradigm for Central Nervous System Re...
Teixeira, F. G.; Carvalho, M. M.; Sousa, N.; Salgado, A. J.The low regeneration potential of the central nervous system (CNS) represents a challenge for the development of new therapeutic strategies. Mesenchymal stem cells (MSCs) have been proposed as a possible therapeutic tool for CNS disorders. In addition to their differentiation potential, it is well accepted nowadays that their beneficial actions can also be mediated by their secretome. Indeed, it was already dem...

Optical and structural properties of GaAs/GaInP quantum wells grown by Chemical...
Martins,M. R.; Oliveira,J. B. B.; Tabata,A.; Laureto,E.; Bettini,J.; Meneses,E. A.; Carvalho,M. M. G.In this work we investigated the optical and structural properties of GaAs/GaInP quantum wells (QW) grown by Chemical Beam Epitaxy (CBE). The samples were characterized by photoluminescence (PL), photoluminescence excitation (PLE) and transmission electron microscopy (TEM). Simulations of the quantum well potential profiles, using the Van De Walle-Martin model, supplemented by our experimental results, allowed ...
Size effects on the growth mode and roughness of sub-micron structures grown by...
Gutiérrez,H.R.; Cotta,M.A.; Nakaema,W.M.; Carvalho,M.M.G.de; Gobbi,A.L.We have observed changes in the morphology of InP films grown in epi-ready substrates and on patterns created by photo and plow-mode AFM lithography. These changes are attributed to different levels of contamination of the surface, which favor nucleation of clusters over a two-dimensional film for the lithography-processed surface. The area of nucleation is smaller than the dimensions of the patterns created by...
