Modification of GaO by an Ag-Cr core-shell cocatalyst enhances photocatalytic CO evolution for the conversion of CO by HO.

A core-shell structure of Ag-Cr dual cocatalyst loaded-GaO was found to significantly enhance the formation rate of CO and selectivity toward CO evolution for the photocatalytic conversion of CO where HO is used as an electron donor.

Enhancement of CO Evolution by Modification of GaO with Rare-Earth Elements for the Photocatalytic Conversion of CO by HO.

Modification of the surface of GaO with rare-earth elements enhanced the evolution of CO as a reduction product in the photocatalytic conversion of CO using HO as an electron donor under UV irradiation in aqueous NaHCO as a pH buffer, with the rare-earth species functioning as a CO capture and storage material. Isotope experiments using CO as a substrate clearly revealed that CO was generated from the introduced gaseous CO. In the presence of the NaHCO additive, the rare-earth (RE) species on the GaO surface are transformed into carbonate hydrates (RE(CO)·nHO) and/or hydroxycarbonates (RE(OH)(CO)) which are decomposed upon photoirradiation.

Linear deposition of immunoglobulins and complement components on the dura in normal pressure hydrocephalus complicating systemic lupus erythematosus.

We present a case of normal pressure hydrocephalus in a 70-year-old man with previously diagnosed systemic lupus erythematosus. Histological examination demonstrated the linear deposition of IgG, IgA, IgM, C(3) and C(1q) on the dura in the absence of inflammation or thrombosis that has previously been implicated in the aetiology of elevated pressure hydrocephalus in systemic lupus erythematosus. Our results suggest that the deposition of immunoglobulins and complement may play a pivotal role in an insidious manner in the pathogenesis of normal pressure hydrocephalus in systemic lupus erythematosus.
