OBJECTIVE Evidence suggests that abnormal iron metabolism is associated with Parkinson disease (PD), with raised iron levels found in pathologically affected areas in PD. It is unknown if this elevated iron is actually associated with neurons or reactive glia, and we therefore addressed this issue by determining if raised iron was present in single(More)
Thin films of TiO2 (anatase) nanoparticles are assembled at an electrode surface via a layer-by-layer deposition process employing phytic acid, pyromellitic acid, or flavin adenine dinucleotide (FAD) as molecular binders. With all three types of binders, layers of typically 30 nm thickness are formed each deposition cycle. FAD as an electrochemically active(More)
The eggshell of the domestic fowl has been studied by transmission electron microscopy and diffraction. Thin sections of shell were prepared by chemical and ion-beam thinning techniques. Each calcite column of the palisade layer consisted of crystallites of diameter 20 to 30 µm with some tendency for crystallite alignment within a single column. Evidence(More)
