Dispositions of deoxynivalenol (DON) in rats and chickens were investigated, using a radiotracer method coupled with a novel γ-accurate radioisotope counting (γ-ARC) radio-high-performance liquid chromatography ion trap time-of-flight tandem mass spectrometry (radio-HPLC-IT-TOF-MS/MS) system. 3β-(3)H-DON was chemically synthesized and orally administrated(More)
In this study, we present a rapid and simple method for the separation and direct detection of glutathione by combining gold nanoparticles and MALDI-TOF-MS with graphene as matrix. Gold nanoparticles enable the selective capture of thiol-containing compounds. Gold nanoparticles bound with analytes can be mixed with graphene matrix for direct analysis by(More)
Firstly, the characteristics of tacit requirements are analyzed. Then the knowledge conversion of requirement elicitation from socialization to externalization, to combination and to internalization are exported according to SECI Spiral Model. These processes are processes dealing with tacit and explicit requirements. And when analyzing the knowledge flow,(More)
Though T-2 toxin is the most harmful mycotoxin to the fetuses, it remains unclear whether T-2 toxin and its major metabolite, HT-2 toxin, could pass the placenta into the fetus and which kind of placental transport is involved in the passage. To illustrate their placenta transfer mechanism, the uptake and efflux of T-2 and HT-2 toxins across apical(More)
Fumonisins (FBs) are widespread Fusarium toxins commonly found as corn contaminants. FBs could cause a variety of diseases in animals and humans, such as hepatotoxic, nephrotoxic, hepatocarcinogenic and cytotoxic effects in mammals. To date, almost no review has addressed the toxicity of FBs in relation to oxidative stress and their metabolism. The focus of(More)
T-2 toxin, a major compound of trichothecenes, inhibits protein synthesis and induces inflammation and cell apoptosis through the activation of MAPK pathway. The JAK/STAT pathway has recently been shown to be downstream targets of trichothecenes. However, whether there is any crosstalk between JNK and JAK/STAT pathways in trichothecene toxicity has not been(More)
Four new ruthenium(II) polypyridyl complexes [Ru(dmb)2(DQTT)](ClO4)2 (1) (DQTT=12-(1,4-dihydroquinoxalin-6-yl)-4,5,9,14-tetraazabenzo[b]triphenylene, dmb=4,4'-dimethyl-2,2'-bipyridine), [Ru(bpy)2(DQTT)](ClO4)2 (2) (bpy=2,2'-bipyridine), [Ru(phen)2(DQTT)](ClO4)2 (3) (phen=1,10-phenanthroline) and [Ru(dmp)2(DQTT)](ClO4)2 (4)(More)
Methionine restriction (MR) exerts many beneficial effects, such as increasing longevity, decreasing oxidative damage and alleviating inflammatory responses. Much attention has been recently focused on the effects of MR on metabolic health, especially lipid metabolism, since the increasing incidence of obesity, insulin resistance and type 2 diabetes causes(More)
OBJECTIVE To explore the effect of grape seed proanthocyanidins (GSPs) on the invasion and migration of A549 lung cancer cells and the underlying mechanism. METHODS Trypan blue dye exclusion assay was used to determine the cytotoxic effect of varying doses of GSPs on the BEAS-2B normal human pulmonary epithelial cells. After treated with 0, 10, 20, 40, 80(More)
After field survey and literature review, we found that software requirement development (SRD) is a knowledge creation process, and knowledge creation theory of Nonaka is appropriate for analyzing knowledge creating of SRD. The characteristics of knowledge in requirement elicitation process are analyzed, and dissymmetric knowledge of SRD is discussed.(More)
