      CDK5 plays an important role in neurotransmission and synaptic plasticity in the normal function of the adult brain, and dysregulation can lead to Tau hyperphosphorylation and cognitive impairment. In a previous study, we ...
    • Molina Reyes, Emiliano; Cataldo, Vicente F.; Eggers, Cristián; Muñoz Madrid, Valentina Elisa; Glavic Maurer, Alvaro Alberto (Frontiers Media, 2022)
      Cells extend membrane protrusions like lamellipodia and filopodia from the leading edge to sense, to move and to form new contacts. The Arp2/3 complex sustains lamellipodia formation, and in conjunction with the actomyosin ...
    • Maldonado, Antonio; Villagrán, Carolina (2002)
      Pollen analysis of two sediment records from a coastal swamp forest site in the Chilean semiarid region (31°50′S; 71°28′W) shows an alternation of dry and wet phases during the past ∼6100 cal yr B.P. The most prominent ...
    • Halac, S.; Mengo, L.; Guerra, Lucía; Lami, A.; Musazzi, S.; Loizeau, J. L.; Ariztegui, D.; Piovano, E.L. (Elsevier, 2020)
      Reservoirs hold a detailed record of the changes in the input of sediments and nutrients over decades to centuries. Paleolimnological multi-proxy analysis makes it possible to reconstruct baseline conditions to infer early ...

    • Bravo, Paz; Isaacs, Fabiola; Ramírez, Galo; Armijo, Francisco; Isaacs Casanova, Mauricio; Aguirre, María Jesús; Zamora, Claudia; Trollund, Ejnar (SOCIEDAD CHILENA DE QUIMICA, 2005-12)
      The aim of this work was the study of three different modified electrodes where the substrate and the porphyrin used to modify the electrodic surface was the same. The surface electrode was a glass covered by a layer of ...
    • Pastenes Villarreal, Claudio; Porter, Victor; Baginsky, Cecilia; Norton, Peter; González, Javiera (Elsevier GmbH, 2004)
      In order to estimate the importance of leaf movements on photosynthesis in well-watered and water-stressed field grown bean cultivars (Arroz Tuscola (AT), Orfeo INIA (OI), Bayos Titan (BT), and Hallados Dorado (HD)), CO2 ...
    • Pardo Gandarillas, María Cecilia; Ibánez, Christian M.; Ruiz, J. Francisco; Bustos, Claudia A.; Peña, Fabiola A.; Landaeta, Mauricio F. (Elsevier, 2016)
      Cephalopods are common in Chilean waters; however, there is little information on the distribution and abundance of their early life stages. In the austral spring seasons of 2008 and 2009 zooplankton samples were collected ...
    • Fernández M., Morales C., Durán E., Fernández-Colleman S., Sentis E., Mpodozis J., Karten H.J., Marín G.J. (Wiley-Liss Inc.info@wiley.com, 2020)
    • Gómez Jeria, Juan; Ojeda Vergara, Mario (Sociedad Chilena de Química, 2003-09-22)
      We present a physically based treatment of the molecular rotational partition function for the case of the interaction of a macromolecular receptor with a small biologically active molecule. This leads to the proposal ...
