The ignited state kinetics can be fit quantitatively using directly a Langmuir Henshelwood bimolecular rate expression with a heat of adsorption of NO of 32 4 kJ/mol and of CO of 106 7 kJ/mol, respectively.展开更多

These two microelectrodes are suitable for the measurement. In natural seawater, the sensitivity and stability of the ISO-NOPMC microsensor are higher than that of the homemade Nafion and Co(Salen) modified platinum microelectrode.展开更多

Methods： The pathological diagnosis of glioma and tumor classification was by HE staining, and we use immunohistochemistry method to analyse the level of nNOS in different pathological grade glioma and the expression level of Cyt-c in mitochondria meanwhile. Results： The levels of nNOS were highest in grade Ⅲ tumors, moderate in grade Ⅱ tumors, and lowest different in grade I tumors. There was significant difference of the nNOS levels among different pathological grade tumors （P 〈 0.05）. Furthermore, the similar phenomenon was observed in the expression level of Cyt-c in mitochondria （P 〈 0.05）. Conclusion： The expression level of nNOS and Cyt-c in mitochondria was significantly related to the pathological grade of glioma.展开更多
