Selectively electrolyzing CO to ethylene by a Cu-CuO/rGO catalyst derived from copper hydroxide nanostrands/graphene oxide nanosheets.

Electrolyzing CO into ethylene (CH) is a promising strategy for CO utilization and carbon neutrality since CH is an important industrial feedstock. However, selectively converting CO into CH the CO electro-reduction reaction (CO ERR) is still a great challenge. Herein, Cu-CuO nanoparticles anchored on reduced graphene oxide nanosheets (Cu-CuO/rGO) were prepared from copper hydroxide nanostrands (CHNs) and graphene oxide (GO) nanosheets electrochemical reduction.

Three-D imaging of dental alveolar bone change after fixed orthodontic treatment in patients with periodontitis.

Objectives: The objective of this study was to radiographically quantify bone height and bone density in patients with periodontitis after fixed orthodontic treatment using cone beam computed tomography (CBCT).

Materials And Methods: A total of 81 patients including 40 patients with chronic periodontitis (group 1) and 41 patients with normal periodontal tissues (group 2) were selected. CBCT scanning for anterior teeth were taken before and after orthodontic treatment.

Treatment of pure red cell aplasia associated with multiple myeloma with biclonal gammopathy using cyclosporine A: a case report.

We reported a rare case of pure red cell aplasia in a 44-year-old man with multiple myeloma with biclonal gammophathy (IgG lambda and IgA lambda type) with severe anemia. After treatment with bortezomib, adriamycin, and dexamethasone, the patient achieved very good partial response with disappearance of monoclonal gammopathy. However, his anemia was not significantly improved.
