... transferrin–gastrin interaction in iron homeostasis. In the present work, the interaction between gastrins and transferrin has been characterized by surface plasmon resonance and covalent crosslinking. First, ... for the binding of gastrin, and of the regions in gastrin required for the interaction with transferrin, is obviously essential to a full understanding of the interacti...

... the nanowires have a crystalline Si core and an amorphous silicon oxide outer layer. In short, the general morphology and diameters of the annealed nanowires were the same as the as- grown SiNWs. However, ... All rights reserved. 1. Introduction Silicon nanowires (SiNW) have attracted much attention since large scale synthesis of SiNWs was achieved [1±3]. This achievement is m...
