Aiming at two key issues in the molecular design of high-spin moleculesand organic ferromagnets, i.e., the ferromagnetic coupling strength in localradical fragments and the changeover of coupling capabilities offerromagnetic coupling units in building high-spin molecules, we made anextensive and deep investigation on numerous important conjugated radicalsystems within the semiempirical and nonempirical VB model, respectively.

Through the considering of two kinds of prior information—conjugate priorand noninformative prior,and by use of the method of Bayesian analysis,we obtain that the posteriordistribution of parameter in the model is approximate to Normal distribution.

1 Heptane, it was revealed that the Cr〓/ Catsan and ZnCl〓 could catalyze the Michael addition of pyrrole with conjugate olefine at α-position of pyrrole to get mono- or bi-Michael addition product selectively under mild condition in good yield. Totally, forty-six new compounds, including thirty target compounds, were prepared.

In addition, the invention further relates to a catalyzer combination used for polymerizing a conjugated dialkene monomer and the anions of an optional mono-vinyl aromatic hydrocarbon into a polydiene polymer having high and medium vinyl content. The catalyzer combination comprises an organolithium compound used as an anionic polymerization initiator, at least an alkali metal alkoxide compound expressed by the formula as a structure regulator.

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.

实验材料为初代培养之牛角膜内皮细胞和全厚度之兔子眼角膜，使用sodium orthovanadate作为酪胺酸磷酸脢的抑制剂，接著以不同SOV浓度(25， 50， 100μM)及不同时间(8， 24 hrs)来处理初代培养之细胞与新鲜的兔子眼角膜，之后进行萤光染色并使用萤光显微镜及共轭焦显微镜进行影像撷取，以观察位於细胞与细胞间的蛋白质，例如：N-cadherin， alpha-catenin 和p120的改变，另外也使用Ki67抗体来侦测是否有进入cell cycle的细胞。

The high-mettled animal that is restive in the yoke only galls his shoulders; and every one will understand the difference between the restless starling of which Sterne has written, breaking its wings against the bars of the cage, and crying,"I can't get out, I can't get out," and the docile canary that sits upon its perch and sings as if it would outrival the lark soaring to heaven's gate.

一只负轭的动物，如果倔强挣扎，结果无非擦伤它自己的颈肩。所以让我们不学愚昧好动的掠鸟，用翅膀拍扑鸟笼，结果反拍伤了自己的翅膀；让我们来作驯良的金丝雀，静坐在栖木上歌唱。
