    Tris{2-[(2-aminobenzylidene)amino]ethyl}amine por Elizondo García, Mariana, Bernés Flouriot, Sylvain Jean, Pérez Rodríguez, Nancy, Elizondo Martínez, Perla

    Publicado 2010
    “…With such an arrangement, one amine H atom forms an S(6) motif through a weak N—HN hydrogen bond with the imine N atom, while the other is engaged in an intermolecular N—H contact involving the benzene ring of a neighbouring molecule related by inversion. The benzene rings also participate in an intramolecular C— H contact of similar strength. …”

    Effects of pericytes and colon cancer stem cells in the tumor microenvironment por Garza Treviño, Elsa Nancy, Delgado González, Paulina, Valencia Salgado, Carlos I., Martínez Garza, Alejandra Mayela

    Publicado 2019
    “…In recent years, it has been shown that the main reason for drug resistance is the presence of colon cancer stem cells (CSC). Pericytes are also capable of tumor homing and are important cellular components of the tumor microenvironment (TME), contributing to the formation of vessels and promoting metastasis; however, they have not been considered very important as a therapeutic target in cancer. …”

    Conditional betas and Market re-definition: Revisiting the capital asset pricing model with Mexican data por Treviño Villarreal, María de Lourdes

    Publicado 2012
    “…The results suggested, however, that it is necessary to allow for time variations in betas as well in order to explain the variations of the monthly average returns. A size effect was also found, although it is not very important. In spite of the empirical support found for the conditional CAPM over the static CAPM, both specifications explain about half of the monthly average return variation, which calls for differences in the pricing of risk between developed and emerging countries…”

    Two-stage melting of au-pd nanoparticles por Mejía Rosales, Sergio, Fernández Navarro, Carlos Javier, Pérez Tijerina, Eduardo, Montejano Carrizales, Juan Martín, Yacamán, Miguel José

    Publicado 2006
    “…We found that the melting transition temperature has a strong dependence on the relative concentrations of the atomic species. We also found that, previous to the melting transition, the outer layer of the nanoparticle gets disordered in what can be thought as a premelting stage, where Au atoms near the surface migrate to the surface and remain there after the particle melts as a whole. …”
