Linear Bending Wave Propagation in Laminar and Turbulent Disks by Callum W. Fairbairn

“…Although the turbulence can be quantified with an effective α parameter, the bending waves behave distinctly from a classical viscous evolution and are readily disrupted when the turbulent velocity is comparable to the induced warping flows. This may have implications for the inclination damping rates induced by planet–disk interactions, the capture rate of black holes in active galactic nucleus disks or the warped shapes assumed by disks in misaligned systems.…”

Insecticide chlorfenapyr confers induced toxicity in human cells through mitochondria-dependent pathways of apoptosis by Longfei Wang, Zheng Qu, Yifan Xu, Guangqing Yu, Xiangyang Liu, Meizi Wang, Shiheng An, Xinming Yin, Risong Na, Youwu Hao

“…Chl's ability to induce DNA damage and apoptosis in human cells was confirmed through alkaline comet assay, immunofluorescence assay, and flow cytometric analysis. Further research showed that Chl induced mitochondrial damage (the collapse of mitochondrial membrane potential and the opening of mitochondrial permeability transition pore) with up-regulated expression of Bax/Bcl-2 leads to the release of cytochrome c from mitochondria which in turn activated the apoptotic pathway. …”
