Preparation of an antibody-colloidal gold probe (conjugate) specific to aflatoxin B1 (AFB1) and its use in developing a rapid AFB1 diagnostic method was presented in this paper. Monodispersional nanogold colloid was synthesized and preparation of nanogold-labeled polyclonal antibody probe to aflatoxin B1 under friendly and optimal condition. Combination of(More)
Numblike (Numbl), a conserved homolog of Drosophila Numb, has been proved to be implicated in early development of the nervous system. A recent study also showed that Numbl played an important role in tumorigenesis and invasion by suppressing NF-κB activation. However, the biological role of Numbl remains unknown in lung cancer up to now. To address the(More)
STUDY DESIGN A case report and clinical discussion. OBJECTIVE To describe an unique case of purulent discitis at C3-C4 and an anterior C1-C4 epidural abscess secondary to oxygen-ozone therapy for the herniated cervical discs. SUMMARY OF BACKGROUND DATA Previously reported complications secondary to ozone therapy are rarely documented. No cases of(More)
A spectrophotometric method was developed for the determination of iron(III)-dimethyldithiocarbamate (ferbam) by concerting it into an iron(III)-9-(4-carboxyphenyl)-2,3,7-trihydroxyl-6-fluorone complex. In NH(3)-HAc buffer solution (pH 6.5), the reagent reacts with ferbam to form a blue complex with a maximum absorption peak at 640nm. The reaction can be(More)
A excellent sensitive and selective method for spectrophotometric determination of trace gold has been developed, the method is based on the color reaction of gold(III) with new reagent 5-(2-hydroxy-5-nitrophenylazo)rhodanine (HNAR). Under optimal conditions, HNAR reacts with gold(III) to form a 1:5 orange complex, which has an maximum absorption peak at(More)
The enzymes involved in riboflavin biosynthesis are considered to be potential anti-bacterial drug targets because these proteins are essential in bacterial pathogens but are absent in humans. 3,4-dihydroxy-2-butanone-4-phosphate synthase (DHBPS) is one of the key enzymes in the biosynthesis of riboflavin. DHBPS catalyzes the conversion of(More)
The technique of intelligent ultrasonic pipeline pig was one of the important ways to inspect the wall-loss defects on-line for pipeline. However, a lot of errors or contrary results come forth when the intelligent pig inspecting the wall-loss defects. Aiming at this problem, through the analysis of ultrasonic echo to inspect the corrosion of pipeline wall,(More)
This article seriously analyzed the work procedure of the workflow engine, proposed the overall structure and design model of the workflow engine based on the relational data model, carefully discussed the design plan of the data and process control parts of the workflow engine, and realized the flow control from the data base trigger.
According to the characteristics of radiation interference with communication among modern warships, this paper has proposed a reference-free radiation interference cancellation method to deal with radio communication jamming in a limited space. The method can be adopted to make a proper improvement of the existing LMS algorithm aimed at short-wave(More)
