ZnO nanoparticle-containing carbon composite nanofiber ( ZnO-CNF ) was prepared by the electrospinning of the ZnCl2-PAN precursor, followed by preoxidation and carbonization. The ZnO nanoparticles were uniformly distributed on the surface of the carbon nanofiber with the size of 20-30 nm, confirmed by scanning electron microscopy ( SEM ) . The wettability of the ZnO-CNF was studied by water contact angle test. With Nafion as an additive, the ZnO-CNF modified electrode was successfully constructed by dip-coating. The surface morphology and electrochemical properties of the modified electrode were investigated by SEM and cyclic voltammetry. There was a sensitive response of the ZnO-CNF modified electrode on Pb ions in solution, demonstrated by square wave stripping voltammetry. Under the optimized conditions, a good linear relationship between peak current and Pb2+concentration was obtained in the range of 2. 4×10-10-2. 4×10-7 mol/L (R=0. 998) by 10 min preconcentration at -1. 0 V in 0. 1 mol/L NaAc buffer solution (pH=4. 6). The detection limit was 4. 8×10-11 mol/L. The practical analytical application of the ZnO-CNF modified electrode was assessed by the measurement of the actual water sample and the result was consistent with that obtained by ICP-MS.

Journal of International Oncology 2020;47(5):289-292
Bub1 is essential for assembling of the functional spindle assembly checkpoint (SAC) to guarantee the correct separation of sister chromatids. Abnormal expression of Bub1 can elevate defects in SAC function, chromosome instability, and the incidence of aneuploidy. Several recent studies indicate that aberrantly expressed Bub1 may promote the tumorigenesis via regulating cell proliferation, invasion, migration and cancer stem cell activation. Further understanding of the mechanism of Bub1 in malignancy may provide new targeted therapy strategies.
