The hybrid composite PW11Co/PAMAM was characterized by FT-IR, UV-Vis diffuse reflectance spectra, XPS, XRD and TG/DTA, indicating that the PW11Co was chemically anchored to PAMAM. The morphologies of the title composite were characterized by scanning electron microscopy and transmission electron microscopy. The catalytic activity was evaluated by oxidation of isobutyraldehyde to isobutyric acid in MeCN under mild conditions (20 ℃, ambient pressure), showing that the title compound is a more effective and recoverable catalyst than corresponding PW11Co.

Primary culture of bovine corneal endothelial cells and whole rabbit corneas were used as the experimental materials. We first treated the cultured bovine corneal endothelial cells with PTPs inhibitor, sodium orthovanadate, with a variety of concentrations (25,50,100μM) for various durations (8,24 hrs). The effects of PTP inhibition on cellular distribution of cell-cell junctional proteins, such as N-cadherin, alpha-catenin and p120, were evaluated by immunohistochemical staining with fluorescein microscopy and confocal microscopy. Immunohistochemical staining with Ki67 Ab, a marker of cell proliferation, was also used to detect cells entering cell cycle.
