    • Nitric oxide regulates neurogenesis in adult olfactory epithelium in vitro 
      Sülz, Lorena; Astorga, Guadalupe; Bellette, Bernadette; Iturriaga, Rodrigo; Mackay Sim, Alan; Bacigalupo Vicuña, Juan (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009-02-05)
      Nitric oxide regulates neurogenesis in the developing and adult brain. The olfactory epithelium is a site of neurogenesis in the adult and previous studies suggest a role for nitric oxide in this tissue during development. We ...
    • Testing non-additive effects of nectar-robbing ants and hummingbird pollination on the reproductive success ... 
      Caballero, Paula; Ossa, Carmen G.; Gonzáles, Wilfredo L.; González Browne, Catalina; Astorga, Guadalupe; Murúa, Maureen M.; Medel Contreras, Rodrigo (Springer, 2013)
      Nectar robbing may have an indirect negative effect on plant reproduction by discouraging legitimate pollinator species from visiting robbed flowers. In this study, we set up a 2 9 2 factorial design with nectar-robbing ...
    • Uncoupling the MgATP-induced inhibition and aggregation of Escherichia coli phosphofructokinase-2 by ... 
      Báez, Mauricio; Merino, Felipe; Astorga, Guadalupe; Babul Cattán, Jorge (ELSEVIER, 2008-06-11)
      Binding of MgATP to an allosteric site of Escherichia coli phosphofructokinase-2 (Pfk-2) provoked inhibition and a dimer-tetramer (D-T) conversion of the enzyme. Successive deletions of up to 10 residues and point mutations ...
