Surface-Group-Oriented, Condensation Cyclization-Driven, Nitrogen-Doping Strategy for the Preparation of a Nitrogen-Species-Tunable, Carbon-Material-Supported Pd Catalyst.

A nitrogen-carbon framework with the thickness of several molecules was fabricated through a straightforward nitrogen-doping strategy, in which specially designed surface-oxygen-containing groups (SOGs) first introduced onto the porous carbon support were used to guide the generation of a surface-nitrogen-containing structure through condensation reactions between SOGs and the amidogen group of organic amines under hydrothermal conditions. The results indicate that different kinds of SOGs generate different types and abundances of N species. The CO-releasing groups are apt to form a high proportion of amino groups, whereas the CO-releasing groups, especially carboxyl and lactones, are mainly transformed into pyrrolic-type nitrogen.

Clinical observation of the efficacy of low-molecular-weight heparin calcium in prophylaxis of the deep venous thrombosis following the gynecological tumor surgery.

Present study is conducted to investigate the efficacy and safety of application of low-molecular-weight heparin calcium in the prophylaxis of deep venous thrombosis (DVT) following the laparoscopic surgery for gynecological tumors, so as to provide reference for the selection of anti-coagulant procedure in clinical practice. A total of 180 patients who underwent the laparoscopic surgery for the gynecological tumors in this hospital between January 2015 and December 2017 were enrolled in this study, and according to the anti-coagulant procedure, they were divided into two groups, i.e.

ATF5 is overexpressed in epithelial ovarian carcinomas and interference with its function increases apoptosis through the downregulation of Bcl-2 in SKOV-3 cells.

The activating transcription factor 5 (ATF5) is highly expressed in many kinds of tumors including glioblastoma and breast cancers, but its expression in epithelial ovarian neoplasms has not been investigated. Here, we show that ATF5 is highly expressed in the majority of epithelial ovarian cancer samples (43/60) as compared with benign ovarian tumor tissues (4/13) and normal ovarian tissues (1/10). Furthermore, we found that ATF5 expression significantly correlated with advanced clinical stage (P<0.
