Metal coordination polymer nanoboxes are reported for the first time. Initially spherical miniemulsion droplet templates were transformed to hollow cubic crystalline nanostructures via a miniemulsion periphery polymerization conducted under benign thermal and chemical conditions.

Ring sideroblasts Ring sideroblasts are erythroblasts with iron-loaded mitochondria visualized by Prussian blue staining (Perls’ reaction) as a perinuclear ring of blue granules (Figures 1D and 2C). The International Working Group on Morphology of Myelodysplastic Syndrome (IWGM-MDS) recommended that ring sideroblasts be defined as erythroblasts in which there are a minimum of five siderotic gra...
