    ..Due to the continuous presence of DHAA into water systems, results from this study provide indications as to the potential impacts of DHAA and demonstrate the importance of this class of chemicals on aquatic organisms. ..
  8. Venables M, Navarro Martín L, Basak A, Baum B, Zhang D, Trudeau V. Characterization of multiple nestin isoforms in the goldfish brain. Comp Biochem Physiol Part D Genomics Proteomics. 2016;19:8-17 pubmed publisher
    ..Studying the differential roles and regulation of these nestins could lead to a better understanding of cellular remodeling during neurogenesis and the unparalleled regenerative abilities after damage in the teleost CNS. ..
