The catalytic activity of PtCu (n = 1-3, m = 0-2) clusters for methanol dehydrogenation to CO.

A large number of experiments show that PtCu catalyst has a good catalytic effect on methanol decomposition. Therefore, density functional theory (DFT) was used to further study the dehydrogenation of methanol catalyzed by PtCu (n = 1-3, m = 0-2). The energy diagrams of O-adsorption path and H-adsorption path were drawn.

IL-24 Induces Apoptosis via Upregulation of RNA-Activated Protein Kinase and Enhances Temozolomide-Induced Apoptosis in Glioma Cells.

Human interleukin-24 (IL-24) has been found recently to play a tumor-suppressor role in a variety of tumors, including gliomas. However, the exact mechanism of glioma tumor suppression by IL-24 remains unclear. We collected by surgery 30 gliomas at different grades and evaluated IL-24 and double-stranded RNA-activated protein kinase (PKR) expression using fluorescence quantitative real-time PCR and immunohistochemical techniques.
