A new method for ab initio energy partition is being developed in order to gain new insight into the nature of electron delocalization, and it is able to provide any molecule with a fragment MO basis set in which the π and σ systems have been separated out no matter whether molecule is planar or nonplanar as well as whether the π system is conjugated or cumulated.

我们的方法可以为任何一个共轭分子(无论是平面的还是非平面的，是含共轭双键的还是含累积双键的)，提供一个π与σ体系彻底分离的片断分子轨道基组。这个轨道基组不仅满足分子特殊的对称性，而且还具有确切的电子占据数。

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.
