The Effect of Calycosin-7-O-β-D-Glucoside and its Synergistic Augmentation of Cisplatin-induced Apoptosis in SK-OV-3 Cells.

Objective: This study aims to examine the synergetic augmentation of calycosin-7-O-β-D-glucoside (CG) on cisplatin (CDDP) to induce apoptosis of human epithelial ovarian SK-OV-3 cancer cells.

Methods: The SK-OV-3 cells were divided into four groups: control, CDDP monotherapy, CG monotherapy, and combined CDDP and CG treatment. The cell counting kit-8 method detected cell proliferation at different times and under different treatments.

Does LIN28B gene dysregulation make women more likely to abort?

Background: LIN28B plays an important role in early embryonic development, but its role in villous trophoblast implantation and differentiation remains unknown. This study aims to verify the role of LIN28B in trophoblastic villous tissue and cells from women with URSA (unexplained recurrent spontaneous abortion) and artificial termination of pregnancy (negative control, NC).

Methods: The gene and its protein expression level were detected with real-time quantitative PCR, Western immunoblotting analysis, and immunocytochemistry.

Semi-active control of a cable-stayed bridge under multiple-support excitations.

This paper presents a semi-active strategy for seismic protection of a benchmark cable-stayed bridge with consideration of multiple-support excitations. In this control strategy, Magnetorheological (MR) dampers are proposed as control devices, a LQG-clipped-optimal control algorithm is employed. An active control strategy, shown in previous researches to perform well at controlling the benchmark bridge when uniform earthquake motion was assumed, is also used in this study to control this benchmark bridge with consideration of multiple-support excitations.
