A new chemiluminescence (CL) method is proposed for the determination of chlorpromazine hydrochloride, which is based on the dichloromethane solvent extraction of ion-pair complex of tetrachloroaurate(III) with chlorpromazine hydrochloride and luminol chemiluminescence detection in a reversed micellar medium formed by the cation surfactant(More)
This paper reports a quantum dot (QD)-based "off-on" fluorescent biosensor specifically for the determination of glutathione (GSH) with high sensitivity. The biosensor was based on the following two properties. Firstly, the high fluorescence of N-acetyl-L-cysteine (NALC) capped CdTe QDs could be effectively quenched by Hg(2+) due to the binding of Hg(2+) to(More)
This paper discusses a method to find the acoustic properties of different types of background noise: highway, airport, subway, restaurant, rain, inside a car, and inside a train. Four parameters are calculated using the Auto Correlation Function (ACF). These parameters are energy (at the origin of delay ¿(0)) the amplitude of the first positive peak of the(More)
A fluorescent "turn off-on" pattern for the detection of herring sperm DNA (hsDNA) had been designed through utilizing the interaction between polymyxin B sulfate (PMBS) and hsDNA as an inherent performance and the fluorescent transformation of glutathione (GSH)-capped CdTe quantum dots (QDs) as an external manifestation. Due to the occurrence of the(More)
Although various strategies have been reported for double-stranded DNA (DNA) detection, development of a time-saving, specific, and regeneratable fluorescence sensing platform still remains a desired goal. In this study, we proposed a new DNA detection method that relies on an "off-on" switch of a regenerated fluorescence biosensor based on an electron(More)
BACKGROUND Pregnancy-associated plasma protein A (PAPPA) is an emerging biomarker used in various medical fields but has yet to be evaluated in critical care medicine. This study evaluates the value of PAPPA as a biomarker in predicting myocardial dysfunction and 28-day mortality in patients with severe sepsis. METHODS Serum concentrations of PAPPA and(More)
Fluorescent carbon dots was prepared by heating N-(2-hydroxyethyl)ethylene diaminetriacetic acid in air. The carbon dots were not only highly soluble in water but also uniform in size, and possessed strong blue fluorescence and excitation wavelength-dependent emission properties with the maximum excitation and emission wavelength at 366nm and 423nm,(More)
