Bio-inspired semi-transparent silver nanowire conductor based on a vein network with excellent electromechanical and photothermal properties.

A bio-inspired conductive binary-network of vein-silver nanowires (AgNWs) was embedded in poly(dimethylsiloxane) (PDMS) to prepare a semi-transparent stretchable conductor (vein-AgNWs-PDMS) by a simple dipping process. The special conductive structure was constructed by using veins with a porous structure as an ideal skeleton to load AgNW networks, which allowed the vein-AgNWs-PDMS composite to show a low sheet resistance of 1 Ω sq with 74% transmittance. The figure of merit of vein-AgNWs-PDMS is as high as 2502 and can be adjusted easily by controlling the times of the dipping cycle.

MDM2 promotes epithelial-mesenchymal transition and metastasis of ovarian cancer SKOV3 cells.

Background: Metastasis accounts for the most lethal reason for the death of ovarian cancer patients, but remains largely untreated. Epithelial-mesenchymal transition (EMT) is critical for the conversion of early-stage ovarian tumours into metastatic malignancies. Thus the exploration of the signalling pathways promoting EMT would open potential opportunities for the treatment of metastatic ovarian cancer.

[A control study of a school-based life skills education on prevention of behavior problems in third-grade schoolchildren].

Objective: To evaluate the effectiveness on the prevention of behavior problems of life skills education combining school-based and parent-involved approaches for third-grade students in China.

Methods: This research was targeted at the population of third-grade children in two elementary schools in Qinhuangdao City, Hebei Province. Nine regular school classrooms were randomly divided into three groups: the intervention group (n=208), internal control group (n=209) and external control group (n=204).
