This paper studies the problem of Raptor-code design for binary-input AWGN (BIAWGN) channels using the mean-LLR-EXIT chart approach presented in [1]. We report that there exist situations where such a design approach may fail or fail to produce capacity-achieving codes, for certain ranges of channel SNR. Suggestions and discussions are provided pertaining(More)
Agonist-induced internalisation of receptors may lead to the formation of signalling endosomes. There is little evidence relating to whether this occurs to native receptors in non-transformed cells, and no previous studies asking whether this endosomal signalling can promote cell cycle progression in non-transformed cells. We investigated the hypothesis(More)
Acidic endo-polygalacturonases are the major part of pectinase preparations and extensively applied in the clarification of fruits juice, vegetables extracts, and wines. However, most of the reported fungal endo-polygalacturonases are active and stable under narrow pH range and low temperatures. In this study, an acidic endo-polygalacturonase (EPG4) was(More)
Successive projections algorithm combined with partial least squares regression, termed as SPA-PLS approach, was implemented as a novel variable selection approach to multivariate calibration. The proposed approach was applied to near-infrared reflectance data for analyzing moisture in wheat. The number of variables selected from 701 spectral variables was(More)
Local recurrence after rectal cancer surgery is conceived to result from microscopically incomplete resection. We aimed to investigate the patterns of mesorectal neoplastic foci, and examined the involvement and micrometastasis of lymph nodes. Observation of large tissue slice and analysis of tissue microarray were integrated in the pathological study of 31(More)
AIM To assess the feasibility and efficacy of laparoscopic total mesorectal excision (LTME) of low rectal cancer with preservation of anal sphincter. METHODS From June 2001 to June 2003, 82 patients with low rectal cancer underwent laparoscopic total mesorectal excision with preservation of anal sphincter. The lowest edge of tumors was below peritoneal(More)
AIM To discuss the clinical significance of postoperative gastrointestinal decompression in operation on lower digestive tract. METHODS Three hundred and sixty-eight patients with excision and anastomosis of lower digestive tract were divided into two groups, i.e. the group with postoperative gastrointestinal decompression and the group without(More)
Vitexin-4″-O-glucoside (VOG), being a main component in the leaves of Crataegus pinnatifida Bge. var. major, was isolated and then three different doses (20, 40, and 60 mg/kg) of VOG were administered intravenously to rats. To study its pharmacokinetics, a simple and rapid HPLC method was developed using hesperidin as internal standard and the relative(More)
OBJECTIVE To evaluate the clinical necessity of postoperative gastrointestinal decompression after operation on lower digestive tract. METHODS Three hundred and sixty-eight patients who required excision and anastomosis of lower digestive tract were randomly divided into two groups, with or without receiving gastrointestinal decompression after operation.(More)
Currently, there is still a lack of an optimal treatment for no reflow phenomenon (NRP). We analyzed the efficacy and safety of using nondihydropyridine calcium channel antagonists (NDHP, verapamil/diltiazem) in patients suffering from NRP. Eight RCTs with 494 participants were eligible for analysis. The pooling analysis showed that intracoronary(More)
