Three-dimensional strategies involving the application of parallel factor analysis (PARAFAC) to the kinetic UV absorbance measurements were elaborated to monitor the oxidation of quercetin with oxidant agents (K2Cr2O7 and KIO3) and to quantify analyte in a dietary supplement product. Loadings (spectral, kinetic and concentration profiles) were obtained by the PARAFAC deconvolution. Spectral identification, kinetics and quantification of the relevant analyte in the presence of interferent(s) were performed. The elaborated chemometric strategies were carefully validated to demonstrate the capability of the method. Assay results of the PARAFAC strategies were statistically compared to that of …

Steroidogenic acute regulatory protein (StAR) plays a critical role in the regulation of progesterone (P4) production. Resveratrol (RSV), a natural polyphenol, has beneficial effects on reproductive function. However, its effects on StAR expression and P4 production in human granulosa cells remain undetermined. In this study, we showed the treatment of RSV upregulated StAR expression in human granulosa cells. G protein-coupled estrogen receptor (GPER) and ERK1/2 signaling were involved in RSV-stimulated StAR expression and P4 production. In addition, the expression of a transcriptional repressor, Snail, was downregulated by RSV, which contributed to the RSV-induced induction of StAR expression and P4 production.

This study proposes the use of thiomalic acid–modified Au and Ag nanoparticle mixtures (TMA-Au/AgNP mixes) for the selective detection of tricyclazole. Upon the addition of tricyclazole, the color of TMA-Au/AgNP mixes solution changes from orange-red to lavender (red-shift). According to the density-functional theory calculations, tricyclazole-induced aggregation of TMA-Au/AgNP mixes through electron donor–acceptor interactions was proved. The sensitivity and selectivity of the proposed method are affected by the amount of TMA, volume ratio of TMA-AuNPs to TMA-AgNPs, pH value, and buffer concentration. The ratio of absorbance (A654/A520) of TMA-Au/AgNP mixes solution is proportional to the concentration of …

Ractopamine has been authorized as a feed additive and permitted in animal husbandry. With the establishment of the regulation to limit the concentration of ractopamine, a rapid screening method for ractopamine is urgently needed. Additionally, how to combine the screening and confirmatory tests of ractopamine is also critical to maximizing the efficiency of testing. Here, we developed a lateral flow immunoassays-based method for the screening of ractopamine in foods and proposed a cost-benefit analysis approach to optimize cost allocation between screening and confirmatory tests. After verifying the analytical and clinical performance of the screening method, a mathematical model was established …
