Self-Supplied Electron Photoelectrochemical Biosensor with PTB7-Th as a Photoelectric Material and Biotin as an Efficient Quencher.

In this work, a self-supplied electron photoelectrochemical (PEC) biosensor for sensitive determination of Pb was established by utilizing donor-acceptor (D-A)-type PTB7-Th (poly{4,8-bis[5-(2-ethylhexyl) thiophen-2-yl]benzo[1,2-,4,5-']dithiophene-2,6-diyl-alt-3-fluoro-2-[(2-ethylhexyl)carbonyl] thieno[3,4-]-thiophene-4,6-diyl}) as a photoelectric material coupled with biotin as an efficient signal quencher. Impressively, compared with the traditional PEC signal quenchers, biotin was first applied as a PEC signal quencher in this work and it effectively avoided a cumbersome preparation process, complex DNA sequence design, and extra reagent assistance and greatly simplified experimental steps, which could achieve an efficient PEC signal quenching toward PTB7-Th. In addition, the execution of a DNAzyme-assisted Pb recycling amplification reaction could release the quencher biotin, leading to the recovery of the PEC signal, thereby realizing the quantitative detection of Pb.

Expression Profiles of Six Atherosclerosis-Associated microRNAs That Cluster in Patients with Hyperhomocysteinemia: A Clinical Study.

The aim of this study is to discuss the hypothesis that expression of plasma atherosclerosis-associated microRNAs (miRNAs) in hyperhomocysteinemia (Hhcy) patients could predict the presence of atherosclerosis from different channels.

Expression of the above six plasma circulating miRNAs revealed significant upregulation of two miRNAs (miR-133 and miR-217) and downregulation of three miRNAs (miR-145, miR-155, and miR-222).
