More than 200 people in China suffered illness with symptoms of diarrhetic shellfish poisoning (DSP) following consumption of mussels (Mytilus galloprovincialis). The event occurred in the cities of Ningbo and Ningde near the East China Sea in May, 2011. LC-MS/MS analysis showed that high concentrations of okadaic acid, dinophysistoxin-1, and their acyl(More)
Vibrio harveyi has been reported to enter into a viable but nonculturable (VBNC) state. One marine V. harveyi strain, SF1 became nonculturable when incubated in seawater microcosm at 4 °C within 60 days. We investigated protein expression in the exponential phase of V. harveyi SF1 and compared it to the VBNC state. Cytosolic proteins were resolved by(More)
Understanding the interaction of (-)-epigallocatechin-3-gallate (EGCG) and lipase is important for understanding EGCG's inhibition of lipase. In this paper, the interaction of EGCG and porcine lipase was characterized by fluorescence spectroscopy, circular dichroism (CD), isothermal titration calorimetry, and molecular docking. EGCG might act as a(More)
Antibiotic fitness and acquired resistance are the two critical factors when bacteria respond to antibiotics, and the correlations and mechanisms between these two factors remain largely unknown. In this study, a TMT-labeling-based quantitative proteomics method was used to compare the differential expression of proteins between the fitness and acquired(More)
An algorithm of Probabilistic Neural Network (PNN) for bacterial identification based on the probability matrix of API 20E system as a case study is reported. The PNN shows the correct identification of all the taxa belonging to the training and test sets and possesses merits over the conventional methods.
In order to establish a specific identification method for genetically modified (GM) wheat, exogenous insert DNA and flanking sequence between exogenous fragment and recombinant chromosome of GM wheat B73-6-1 were successfully acquired by means of conventional polymerase chain reaction (PCR) and thermal asymmetric interlaced (TAIL)-PCR strategies. Newly(More)
The loop-mediated isothermal amplification (LAMP) assay indicates a potential and valuable means for genetically modified organism (GMO) detection especially for its rapidity, simplicity, and low cost. We developed and evaluated the specificity and sensitivity of the LAMP method for rapid detection of the genetically modified (GM) maize T25. A set of six(More)
Exogenous fragment sequence and flanking sequence between exogenous fragment and recombinant chromosome of transgenic wheat B72-8-11b were successfully acquired through PCR amplification with cross-matched primers from exogenous genes. Newly acquired exogenous fragment covered the full-length sequence of transformed genes such as transformed plasmid and(More)
The exogenous fragment sequence and flanking sequence between the exogenous fragment and recombinant chromosome of transgenic wheat B102-1-2 were successfully acquired using genome walking technology. The newly acquired exogenous fragment encoded the full-length sequence of transformed genes with transformed plasmid and corresponding functional genes(More)
The reliable, simple and easy to operate methods were established to extract DNA from animal feedstuffs. A set of PCR primers were designed for bovine specific mitochondrial DNA sequence. With this method, PCR can be successfully utilized to evaluate the presence of bovine materials in animal feedstuffs. A set of commonly used primers of 18Sr-RNA were(More)
