A Monte Carlo Approach to Measure the Robustness of Boolean Networks

open access: yes, 2012
Emergence of robustness in biological networks is a paramount feature of evolving organisms, but a study of this property in vivo, for any level of representation such as Genetic, Metabolic, or Neuronal Networks, is a very hard challenge.

Epigenetic therapy in allogeneic hematopoietic stem cell transplantation

open access: yesRevista Brasileira de Hematologia e Hemoterapia, 2013
DNA methylation and other epigenetic phenomena appear to be relevant in the pathogenesis of several malignant disorders. DNA methyltransferases add methyl groups to cytosine-phosphate-guanine (CpG) islandsleading to gene promoter silencing.

Images of twins and the notion of the genetic program in the school textbooks of biology: a comparative study held among 15 countries [PDF]

open access: yes, 2007
Genetic concepts have been strongly evolved during these last ten years, and have been found less connected to reductionist or hereditarist values. The aim of the specific research was to analyze and identify if the current school textbooks of biology ...
