(2006)Introduction: Prohepcidin is the precursor of hepcidin, a liver-derived peptide involved in iron metabolism by blocking its intestinal absorption and its release by the reticuloendothelial system. Iron overload and ... -
Effect of 1-year oral alpha-tocopherol administration on anticardiolipin antibodies in hemodialysis patients
Antoniadi, G.; Eleftheriadis, T.; Liakopoulos, V.; Kakasi, E.; Vayonas, G.; Kortsaris, A.; Vargemezis, V. (2005)Background.
