A multiplex polymerase chain reaction (PCR) assay was developed for simultaneous detection of Escherichia coli O157:H7, Bacillus cereus, Vibrio parahaemolyticus, Salmonella spp., Listeria monocytogenes, and Staphylococcus aureus in various Korean ready-to-eat foods. The six specific primer pairs PCR were selected based on the O157 antigen (rfbE) gene E. DNA gyrase subunit B (gyrB) B. toxin regulatory protein (toxR) V. invasion (invA) hemolysin (hly) L. thermonuclease (nuc) S. aureus. 16S...
In contrast to conventional x-ray food inspection systems that have difficulty in detecting low-density materials, a terahertz imaging system can even identify insects and plastics embedded matrix. A reflection-mode continuous-wave was therefore developed for application quality inspection, which requires fast, compact, low-cost detection. High-speed operation of the achieved through use beam-steering tool. reasonable compromise between spatial resolution scan length an aspheric f-theta...
The aim of the present work was to investigate feasibility employing molecular imprinting polymer technique for detecting mycotoxin zearalenone using a surface plasmon resonance (SPR) transducer. molecularly imprinted polypyrrole (MIPPy) film prepared by electropolymerization pyrrole onto bare Au chip in presence template molecule. MIPPy-SPR sensor exhibited linear response range 0.3-3000 ng/mL (R (2) = 0.993) detection zearalenone. selectivity efficiencies and other structurally related...
We propose a widely tunable dual-wavelength Erbium-doped fiber laser that uses two micro-heater-integrated Fabry-Perot diodes (FP-LDs) and Bragg gratings (FBGs) for continuous-wave (CW) terahertz (THz) radiation. Each wavelength can be independently tuned by using an FP-LD FBG. The fine tuning is achieved simultaneously applying current to the micro-heater on strain side-mode suppression ratio more than 35 dB both wavelengths. spacing of dual continuously from 3.2 nm 9.6 nm. Continuous...
β-Caryophyllene (trans-4,11,11-trimethyl-8-methylenebicyclo[7,2,0]undec-4-ene), found in various plants, is a natural bicyclic sesquiterpene with low toxicity. Here, we show that single intraperitoneal injection of β-caryophyllene (10 mg/kg) significantly reduced the cortical infarct volume by 67% when given immediately before middle cerebral artery occlusion (MCAO). Neurological deficits caused MCAO were also decreased β-caryophyllene. treatment cells exposed to oxygen–glucose deprivation...
Food quality monitoring, particularly foreign object detection, has recently become a critical issue for the food industry. In contrast to X-ray imaging, terahertz imaging can provide safe and ionizing-radiation-free nondestructive inspection method sensing. this work, quasi-Bessel beam (QBB) known be nondiffracting was generated by conical dielectric lens detect objects in samples. Using numerical evaluation via finite-difference time-domain (FDTD) method, profiles of QBB were evaluated...
Unlike X-ray systems, a terahertz imaging system can distinguish low-density materials in food matrix. For applying this technique to inspection, resolution and acquisition speed ought be simultaneously enhanced. Therefore, we have developed the first continuous-wave sub-terahertz transmission with polygonal mirror. Using an f-theta lens mirror, beam scanning is performed over range of 150 mm. obtaining images, line-beam incorporated sample translation. The demonstrates that pattern 2.83 mm...
