Scaling up a novel denitrifying microbial fuel cell with an oxic-anoxic two stage biocathode

Peng LIANG, Jincheng WEI, Ming LI, Xia HUANG

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 6,   Pages 913-919 doi: 10.1007/s11783-013-0583-3

Abstract: A scaled up microbial fuel cell (MFC) of a 50 L volume was set up with an oxic-anoxic two-stage biocathode and activated semicoke packed electrodes to achieve simultaneous power generation and nitrogen and organic matter removals. An average maximum power density of 43.1 W·m was obtained in batch operating mode. By adjusting the two external resistances, the denitrification in the A-MFC and power production in the O-MFC could be enhanced. In continuous mode, when the hydraulic retention times were set at 6 h, 8 h and 12 h, the removal efficiencies of COD, and total nitrogen (TN) were higher than 95%, 97%, and 84%, respectively. Meanwhile the removal loads for COD, and TN were10, 0.37 and 0.4 kg·(m ·d) , respectively.

Transformer2 proteins protect breast cancer cells from accumulating replication stress by ensuring productive

Andrew Best,Katherine James,Gerald Hysenaj,Alison Tyson-Capper,David J. Elliott

Frontiers of Chemical Science and Engineering 2016, Volume 10, Issue 2,   Pages 186-195 doi: 10.1007/s11705-015-1540-4

Abstract: Increased expression levels of the RNA splicing regulator Transformer2 (abbreviated Tra2 ) have been reported in several types of cancer. Recent work has revealed an intimate cross-regulation between Tra2 and the highly similar Tra2 protein in human breast cancer cells, though these two proteins are encoded by separate genes created by a gene duplication that occurred over 500 million years ago. This cross-regulation involves splicing control of a special class of exons, called poison exons. Down-regulation of Tra2 reduces splicing inclusion of a poison exon in the mRNA encoding Tra2 , thereby up-regulating Tra2 protein expression. This buffers any splicing changes that might be caused by individual depletion of Tra2 alone. Discovery of this cross-regulation pathway, and its by-pass by joint depletion of both human Tra2 proteins, revealed Tra2 proteins are essential for breast cancer cell viability, and led to the identification of important targets for splicing control. These exons include a critical exon within the checkpoint kinase 1 (CHK1) gene that plays a crucial function in the protection of cancer cells from replication stress. Breast cancer cells depleted for Tra2 proteins have reduced CHK1 protein levels and accumulate DNA damage. These data suggest Tra2 proteins and/or their splicing targets as possible cancer drug targets.
