- Purpose: Astroglial responses after traumatic brain injury are difficult to detect with routine morphological methods. The aims for this study were to compare the temporal and spatial expression pattern of vimentin-and glial fibrillary acidic protein (GFAP) in a weight drop model of mild cerebral contusion injury in the rat. We also wanted to study the vimentin response with immunohistochemistry and vimentin mRNA RT-PCR analysis in severe cortical contusion injury produced by the controlled cortical impact in the mouse. Methods: Vimentin and GFAP immunohistochemistry (1day, 3 days and 7 days) combined with vimentin mRNA RT-PCR analysis (1 h, 4 h, 22 h, 3 days and 7 days) were used after experimental traumatic brain injury in the rat and mouse. Results: Increases in post-traumatic vimentin mRNA levels in the cortex and in the hippocampus appeared together with vimentin immunoreactivity in astrocytes in the perimeter of the cortical lesion, in the subcortical white matter and in the hippocampus starting at one day after severe trauma. GFAP immunostaining revealed hypertrophic astrocytes peaking at day 3 in the perifocal cortical region. There was no significant increase in GFAP immunoreactivity in the white matter in the rat. However, in the mouse there was a slight increase in the number of GFAP positive cells in this region, 3 days after trauma. Overall the pattern of vimentin immunoreactivity was very similar in the rat and mouse. Conclusions: Vimentin immunoreactivity was more sensitive than the GFAP staining method to demonstrate the distribution and time course of astrocyte reactions after a contusion injury, especially in the white matter distant from the cortical lesion.

- The oxygen evolution reaction is a crucial step in water electrolysis to develop clean and renewable energy. Although noble metal-based catalysts have demonstrated high activity for the oxygen evolution reaction, their application is limited by their high cost and low availability. Here we report the use of a molecule-to-cluster strategy for preparing ultrasmall trimetallic clusters by using the polyoxometalate molecule as a precursor. Ultrafine (0.8 nm) transition-metal clusters with controllable chemical composition are obtained. The transition-metal clusters enable highly efficient oxygen evolution through water electrolysis in alkaline media, manifested by an overpotential of 192 mV at 10 mA cm–2, a low Tafel slope of 36 mV dec–1, and long-term stability for 30 h of electrolysis. We note, however, that besides the excellent performance as an oxygen evolution catalyst, our molecule-to-cluster strategy provides a means to achieve well-defined transition-metal clusters in the subnanometer regime, which potentially can have an impact on several other applications.

- The effect of some environmentally relevant factors including salinity, pH, and humic acids on the availability of bisphenol A (BPA) was evaluated by using the negligible-depletion solid-phase microextraction (nd-SPME) biomimetic method. With the variation of salinity (0-500 mM NaCl) and pH (5.0-8.5) of aqueous solutions, the partition coefficients of BPA between the nd-SPME fiber and the aqueous solution varied in the range of logD = 3.55-3.86, which indicates that the salinity and pH can influence the availability of BPA. By using Acros humic acid as model dissolved organic matter (DOM), it was also demonstrated that the environmental factors such as salinity and pH could affect the partitioning of BPA between DOM and aqueous solutions. The determined partition coefficients of BPA between dissolved organic carbon (DOC) and aqueous solutions were in the range of log D-DOC = 4.03-5.60 for Acros humic acid solutions with 1-50 mg l(-1) DOC. The influence of salinity and pH on log D-DOC was more significant at low concentration (0-5 mg l(-1)) of DOC. (c) 2006 Elsevier Ltd. All rights reserved.
