—In this paper, we consider a multiuser single-relay wireless network, where the relay facilitates transmissions of the users' signals to the destination. We study the relay power allocation among the users, and use bargaining theory to model the negotiation among the users on relay power allocation. By assigning a bargaining power to each user to indicate(More)
BACKGROUND Maternal-infant transmission of hepatitis B virus(HBV) occurs even after passive-active immunization. Some scholars speculate that in-utero infection may be the main cause of immunoprophylaxis failure. However, there is a lack of evidence about the possible occurrence periods of perinatal transmission. METHODS From 2008 to 2012, 428 pairs of(More)
BACKGROUND & AIMS FoxO4 is a member of the forkhead box transcription factor O (FoxO) subfamily. FoxO proteins are involved in diverse biological processes. In this study, we examine the role of FoxO4 in intestinal mucosal immunity and inflammatory bowel disease (IBD). METHODS Foxo4-null mice were subjected to trinitrobenzene sulfonic acid (TNBS)(More)
AIM To explore the effects of astragaloside IV (XGA) on myocardial calcium transport and cardiac function in ischemic rats. METHODS Eighty-four Wistar rats were divided into three groups: control group (n=12); ischemic group (n=12) was given isoprenaline injection sc at a dose of 30 mg/kg; and XGA group (n=60) was given XGA after isoprenaline(More)
The intestinal epithelium functions as a physical barrier against the harmful environment of the lumen, which usually becomes impaired in the presence of intestinal diseases. In this work, we introduce an electronic impedance-based analysis using a real-time xCELLigence system to record the dynamic processes of ethanol-induced intestinal barrier(More)
We report the development of a high-sensitivity time-resolved infrared and Raman spectrometer with exceptional experimental flexibility based on a 10-kHz synchronized dual-arm femtosecond and picosecond laser system. Ultrafast high-average-power titanium sapphire lasers and optical parametric amplifiers provide wavelength tuning from the ultraviolet (UV) to(More)
In this paper, a novel electrochemical immunosensor for the determination of casein based on gold nanoparticles and poly(L-Arginine)/multi-walled carbon nanotubes (P-L-Arg/MWCNTs) composite film was proposed. The P-L-Arg/MWCNTs composite film was used to modify glassy carbon electrode (GCE) to fabricate P-L-Arg/MWCNTs/GCE through electropolymerization of(More)
BACKGROUND Numerous studies from Europe and North America have provided a wealth of information regarding the epidemiological and clinical characteristics of inflammatory bowel disease (IBD) in Caucasians. Previous studies in mainland China have been limited by small patient numbers or by lack of detailed information about clinical subgroups of the disease.(More)
AIM To assess the feasibility and usefulness of multi-detector CT enterography with orally administered iso-osmotic mannitol as negative contrast in demonstrating small bowel disease. METHODS Thirteen volunteers and 38 patients with various kinds of small bowel disease were examined. We administered about 1 500 mL iso-osmotic mannitol as negative contrast(More)
Alzheimer's disease (AD) is induced by many reasons, including decreased cellular utilization of glucose and brain cell mitochondrial damages. Degradation product of microbially synthesized polyhydroxybutyrate (PHB), namely, 3-hydroxybutyrate (3HB), can be an alternative to glucose during sustained hypoglycemia. In this study, the derivative of 3HB,(More)
