A novel flow injection chemiluminescent (CL) enzyme immunoassay for clenbuterol analysis based on GoldMag particles is described. GoldMag is a new type of super-paramagnetic Fe3O4/Au composite particle used as a carrier in a flow injection CL system. Clenbuterol conjugated with ovalbumin (OVA) was immobilized onto GoldMag particles and the particles fixed(More)
In this paper, a robust secure spread based image watermarking scheme based on 3-dimensional discrete cosine transform(3D-DCT) is proposed for copyright protection. Firstly, the color image is divided into 3-D blocks, and then these blocks are transformed into transform domain by 3D DCT transform, finally, the generated pseudo random sequence, as the(More)
The mathematical model of DC(direct current) motor as the controlled object is established in this paper,and combines the algorithms of the neural network and PID control.With the self-learning function of the neural network,the self-tunings for parameters of PID are realized. This method can overcome disadvantages of PID as parameters which are difficult(More)
Infantile spasms (IS) syndrome is an age-dependent epileptic encephalopathy, which occurs in children characterized by spasms, impaired consciousness, and hypsarrhythmia. Abnormalities in default mode network (DMN) might contribute to the loss of consciousness during seizures and cognitive deficits in children with IS. The purpose of the present study was(More)
OBJECTIVE Using heteroduplex mobility assay (HMA) to subtype human immunodeficiency virus type 1 (HIV-1) for the purpose of understanding HIV-1 subtype epidemic in Fujian province. METHODS DNA fragments of HIV-1 env gene were amplified from peripheral blood mononuclear cell (PBMC) cocultures of HIV-1 infected individuals by nested polymerase chain(More)
A method based on a simplified sample extraction by matrix solid phase dispersion (MSPD) followed by HPLC determination is validated for analysis of five lignans in Schisandra chinensis. The MSPD parameters that affect the extraction efficiency of lignans from S. chinensis were examined and optimized. The optimal extraction conditions were determined to be(More)
