Improvement in the anemia of hemodialyzed patients following subtotal parathyroidectomy. Evidence for the role of secondary hyperparathyroidism in the etiology of the anemia of chronic renal failure.

Abstract

A double-headed initiator was synthesized yielding two functional groups for the initiation of the nickel mediated ring-opening polymerization of -benzyl-L-glutamate-N-carboxyanhydride and controlled radical polymerization of vinyl monomers via ATRP or NMP. Well-defined block copolymers combining polypeptides and synthetic polymers were obtained.
