    • Analysis of aerosol particles and coarse particulate matter concentrations in Chillan, Chile, 2001-2003 
      Celis, José E.; Flocchini, Robert G.; Carvacho, Omar F.; Morales Peña, José; Zaror, Claudio A.; Inzunza, Juan C.; Pineda, Mario J. (AIR & WASTE MANAGEMENT ASSOC, 2006-02)
      Daily particle samples were collected in Chillan, Chile, at six urban locations from September 1, 2001, through September 30, 2003. Aerosol samples were collected using monitors equipped with a Sierra Andersen 246-b cyclone ...
    • Artificial neural networks applied to quantitative elemental analysis of organic material using PIXE 
      Correa, Rafael; Chesta, Miguel Ángel; Dinator Ramírez, María Inés; Morales Peña, José; Requena, I.; Vila Pinto, Irma (ELSEVIER, 2006-08)
      An artificial neural network (ANN) has been trained with real-sample PIXE (particle X-ray induced emission) spectra of organic substances. Following the training stage ANN was applied to a subset of similar samples thus ...
    • Caracterización de obsidianas del norte y centro sur de Chile mediante análisis de fluorescencia de rayos X 
      Seelenfreund, Andrea; Miranda, Javier; Dinator Ramírez, María Inés; Morales Peña, José (Universidad de Tarapacá, Facultad de Ciencias Sociales Administrativas y Económicas, Departamento de Antropología, 2005-12)
      Con el objeto de estudiar la procedencia de obsidianas encontradas en sitios arqueológicos y caracterizar fuentes de obsidiana en distintas partes de Chile, iniciamos un estudio de caracterización de fuentes por medio de ...
    • Characterisation of aerosol from Santiago, Chile: an integrated PIXE-SEM-EDX study 
      Morata Céspedes, Diego; Polvé, M.; Valdés, A.; Belmar Urbina, Mauricio; Dinator Ramírez, María Inés; Silva, M.; Leiva, M. A.; Aigouy, T.; Morales Peña, José (SPRINGER, 2008-11)
      Santiago de Chile is a big city with huge air quality problems, being one of the most polluted cities in the world. This is aggravated during winter by the topography and meteorological conditions of the city. Although ...
    • Cyclosporine preconditions dendritic cells during differentiation and reduces IL-2 and IL-12 production ... 
      Sauma Mahaluf, Daniela; Fierro, Alberto; Mora, J.R.; Lennon Duménil, Ana María; Bono Merino, María Rosa; Rosemblatt Silber, Mario César; Morales Peña, José (ELSEVIER, 2003-11)
      The mode of action of cyclosporine (CsA) has been ascribed to its capacity to inhibit IL-2 and IFNgamma production by T cells, two cytokines implicated in allograft rejection. Recently, it has been reported that upon ...
    • Di-neutrones en materia neutrónica basados en fuerzas de dos y tres cuerpos 
      Isaule Rodríguez, Felipe Andrés (Universidad de Chile, 2015)
      El estudio de propiedades de muchos cuerpos en materia nuclear ha sido de gran importancia en las últimas décadas. En particular, la materia nuclear rica en neutrones ha cobrado particular interés debido a su importancia ...
    • Generation of dendritic cells with regulatory properties 
      Ureta, G.; Osorio, F.; Morales Peña, José; Rosemblatt Silber, Mario César; Bono Merino, María Rosa; Fierro, J. A. (2007)
      Dendritic cells (DCs) are professional antigen presenting cells with the ability to induce and regulate an immune response. DCs that capture and present antigen under noninflammatory conditions maintain an immature phenotype ...
    • Morphological and Geochemical Analysis of the Laguna Blanca/Zapaleri Obsidian Source in the Atacama Puna 
      Seelenfreund, Andrea; Pino, Mario; Glascock, Michael D.; Sinclaire, Carole; Miranda, Pedro; Pasten Guzmán, Denisse; Cancino, Simón; Dinator Ramírez, María Inés; Morales Peña, José (Wiley Interscience, 2010)
      This paper describes a large obsidian deposit located along the southern banks of Laguna Blanca, on the eastern slope of the Jarellón volcanic caldera near the Chilean–Bolivian border. The obsidian at this site occurs ...
    • Transforming Growth Factor-beta and All-Trans Retinoic Acid Generate Ex Vivo Transgenic Regulatory T Cells ... 
      Moore, C.; Sauma Mahaluf, Daniela; Morales Peña, José; Bono Merino, María Rosa; Rosemblatt Silber, Mario César; Fierro, J. A. (ELSEVIER SCIENCE INC, 2009-07)
      CD4 CD25 Foxp3 regulatory T cells (Treg) mediate immunologic self-tolerance and suppress immune responses. In the gut, a subset of dendritic cells is specialized to induce Treg in a transforming growth factor- (TGF- ...
