Enhancing Kinetics in Sodium Super Ion Conductor NaMnTi(PO) through Microbe-Assisted and Structural Optimization.

Sodium (Na) super ion conductor (NASICON) structure NaMnTi(PO) (NMTP) is considered a promising cathode for sodium-ion batteries due to its reversible three-electron reaction. However, the inferior electronic conductivity and sluggish reaction kinetics limit its practical applications. Herein, we successfully constructed a three-dimensional cross-linked porous architecture NMTP material (AsN@NMTP/C) by a natural microbe of (AsN), and the structure of different NMTP cathodes was optimized by adjusting different transition metal Mn/Ti ratios.

[Inducement effect of ginsenoside Rg3 on apoptosis of human bladder transitional cell carcinoma cell line EJ].

Objective: To explore the effect of Rg3 on inhibiting and inducing apoptosis of bladder cancer cells.

Method: The bladder cancer cell line EJ was treated with Rg3 of various concentrations. Cell proliferation was measured by MTT assay.

[Preliminary study of apoptosis of human hepatocarcinoma cell line HepG2 induced by topotecan].

Background & Objective: Topotecan, a semisynthetic water-soluble derivative of camptothecin, is a potent inhibitor of DNA topoisomerase I and cell cycle specific antitumor agent; The incidence rate of hepatocarcinoma ranks the third in all types of malignant tumor in China. The clinical curative effect of the present treatments and drugs for hepatocarcinoma are not so satisfactory. The inducing effect of topotecan on apoptosis of hepatocarcinoma cell line HepG2 and its cytotoxicity on HepG2 were studied in this paper.
