The use of a colonic stent as a bridge to surgery aims to provide patients with elective one-stage surgical resection while reducing stoma creation and postoperative complications. This study used meta-analytic techniques to compare the outcomes of stent use as a bridge to surgery and emergency surgery in the management of obstructive colorectal cancer. A(More)
DNA computing based image encryption is a new, promising field. In this paper, we propose a novel image encryption scheme based on DNA encoding and spatiotemporal chaos. In particular, after the plain image is primarily diffused with the bitwise Exclusive-OR operation, the DNA mapping rule is introduced to encode the diffused image. In order to enhance the(More)
Texture classification plays an important role in image analysis. The wavelet is a very efficient multiscale analysis method that has been successfully applied to describe the texture. However, it is translation-invariant. The recent double-density discrete wavelet transform have two interesting property, low computational complexity and nearly shift(More)
Uterine leiomyomata are benign, smooth-muscle tumors. The tumors are very common, affecting approximately 10-15 million women in the United States annually. Uterine leiomyomata are often asymptomatic, but may cause symptoms that range in severity from mild abdominal discomfort to uterine prolapse. Several different chromosomal aberrations have been found in(More)
A rapid, inexpensive and reliable method for total RNA extraction from fruiting bodies of Lentinula edodes containing large quantities of polysaccharides and secondary metabolites is described. An initial extraction step using saturated NaCl solution facilitates the separation of nucleic acids from contaminants and, after further extraction with organic(More)
High-throughput Illumina RNA-seq was used for deep sequencing analysis of the transcriptome of poly(A)+ RNA from mycelium grown under three different conditions: 30 days darkness (sample 118), 80 days darkness (313W), and 30 days darkness followed by 50 days in the light (313C), in order to gain insight into the molecular mechanisms underlying the process(More)
Sophocarpine, an effective compound derived from foxtail-like sophora herb and seed, has been reported that it can alleviate non-alcoholic steatohepatitis (NASH) in rats and affect adipocytokine synthesis. Meanwhile, adipocytokines could adjust hepatic lipid metabolism through AMPK signaling pathway. In the work presented here, primary hepatocytes were(More)
AIM To explore the effect of sophocarpine on experimental liver fibrosis and the potential mechanism involved. METHODS Sophocarpine was injected intraperitoneally in two distinct rat hepatic fibrosis models induced either by dimethylnitrosamine or bile duct ligation. Masson's trichrome staining, Sirius red staining and hepatic hydroxyproline level were(More)
BACKGROUND AND AIM Non-alcoholic steatohepatitis (NASH) is one entity in the spectrum of non-alcoholic fatty liver disease (NAFLD). The aim of this study was to explore the prevention and therapeutic effect of sophocarpine on experimental rat NASH. METHODS Sophocarpine with the dosage of 20 mg/kg/day was injected into NASH rats. At the end of 12 weeks,(More)
