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)
Endothelial dysfunction is associated with hypertension, hypercholesterolemia, and heart failure. We tested the hypothesis that spontaneously diabetic Goto-Kakizaki (GK) rats, a model for type 2 diabetes, exhibit endothelial dysfunction. Rats also received a high-sodium diet (6% NaCl [wt/wt]) and chronic angiotensin type 1 (AT(1)) receptor blockade (10(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)
Vascular inflammation is involved in the initiation and progression of atherosclerosis, and is also present in hypertension- and diabetes-induced vascular complications. Angiotensin II (Ang II), the key effector of the renin-angiotensin system (RAS), plays a central role in the regulation of blood pressure and electrolyte homeostasis. There is accumulating(More)
BACKGROUND Cyclosporine (CsA) has significantly improved long-term survival after organ transplantations. Hypertension and nephrotoxicity are common side effects during CsA treatment and are aggravated by high salt intake. OBJECTIVE To examine whether lipoic acid (LA), a natural antioxidant that scavenges reactive oxygen species and regenerates/recycles(More)
We examined whether xanthine oxidoreductase (XOR), a hypoxia-inducible enzyme capable of generating reactive oxygen species, is involved in the onset of angiotensin (Ang) II-induced vascular dysfunction in double-transgenic rats (dTGR) harboring human renin and human angiotensinogen genes. In 7-week-old hypertensive dTGR, the endothelium-mediated relaxation(More)
AIM To perform a meta-analysis to quantitatively summarize the evidence for the association between the Notch signaling pathway and gastric cancer (GC). METHODS An electronic search of the MEDLINE, EMBASE and Chinese National Knowledge Infrastructure, which contain articles published from 1966 onwards, was conducted to select studies for this(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)
