    • Estrés oxidativo, prooxidantes y enfermedad de Crohn 
      Tapia S., Alexis; Araya, Magdalena (2006)
      The frequency of Crohn disease shows a significant increase in the last century. Affected patients show a misbalance between production of free radicals and anti oxidant defenses. Thus, one of the increasingly accepted ...
    • Cop-like operon: Structure and organization in species of the Lactobacillale order 
      Reyes, Angélica; Leiva, Andrea; Cambiazo Ayala, Liliana; Méndez, Marco; González Canales, Mauricio (2006)
