Recently evolved enhancers dominate mammalian gene regulatory landscapes. Mostly exapted from ancestral DNA sequences, many are linked to genes under positive selection. Just as RNA-seq some years ago, unbiased enhancer mapping is on the verge of changing evolutionary research.
There is growing societal and scientific interest in enhancing road verges for nature the environment. This partly because they are estimated to cover large areas some regions. Yet, our knowledge, there has been no quantitative assessment of national verge extent, or habitats encompass. We present a novel method characterising classifying remotely. use this evaluate extent habitat composition a...
Rectovaginal fistula is a postoperative complication of low anterior resection. We investigated the incidence of rectovaginal fistula (RVF) after low anterior resection, its risk factors and its optimal treatment. We analyzed data from 1,493 female patients who underwent low anterior resection for colorectal cancer between January 2006 and March 2016. We calculated the incidence of RVF and perf...
Anal manometry measures circumferential pressures but not axial forces that are responsible for defecation and contribute to fecal continence. Our aims were to investigate these mechanisms by measuring axial rectoanal forces with an intrarectal sphere or a latex balloon fixed at 8, 6, or 4 cm from the anal verge and connected to axial force and displacement transducers. Rectoanal forces and rec...
The 26 sample sites in 7 study plots adjacent to asphalt road and earth road in coastal wetland in the Yellow River Delta were selected to quantify plant diversity using quadrat sampling method in plant bloom phase of July and August 2012. The indice of β T and Jaccard's coefficient were applied to evaluate the species diversity. The results showed that the plant diversities and alien plants we...
