Asymmetric gradient orbital interaction of hetero-diatomic active sites for promoting C - C coupling.

Diatomic-site catalysts (DACs) garner tremendous attention for selective CO photoreduction, especially in the thermodynamical and kinetical mechanism of CO to C products. Herein, we first engineer a novel Zn-porphyrin/RuCu-pincer complex DAC (ZnPor-RuCuDAC). The heteronuclear ZnPor-RuCuDAC exhibits the best acetate selectivity (95.

Meta-Analyses of Association Between BRAF(V600E) Mutation and Clinicopathological Features of Papillary Thyroid Carcinoma.

Background/aims: The function of BRAF V600E as a prognostic biomarker continues controversial by reason of conflicting results in the published articles.

Methods: A systematical literature search for relevant articles was performed in PubMed, Cochrane Library, Google Scholar, Medline and Embase updated to August 5, 2015. The Chi-square test and I2 were employed to examine statistical heterogeneity.
