Occurrence of perfluorinated alkyl substances in sediment from estuarine and coastal areas of the East China Sea.
Environ. Sci. Pollut. Res. Int. 22(3) , 1662-9, (2015) Perfluorinated alkyl substances (PFAS) have drawn much attention due to their environmental persistence, ubiquitous existence, and bioaccumulation potential. The occurrence and spatial variation of PFAS were investigated through collection of riverine and mar... |

Stability of Individual Maillard Reaction Products in the Presence of the Human Colonic Microbiota.
J. Agric. Food Chem. 63 , 6723-30, (2015) Maillard reaction products (MRPs) are taken up in substantial amounts with the daily diet, but the majority are not transported across the intestinal epithelium. The aim of this study was to obtain first insights into the stability of dietary MRPs in the pres... |

Exploring the possibilities of capacitively coupled contactless conductivity detection in combination with liquid chromatography for the analysis of polar compounds using aminoglycosides as test case.
J. Pharm. Biomed. Anal. 112 , 155-68, (2015) The analysis of highly polar (often charged) compounds which lack a strong UV absorbing chromophore is really challenging. Despite the numerous analytical methods published, the demand for a simple, robust and cheap technique for their analysis still persists... |

Ion-pair reversed phase liquid chromatography with ultraviolet detection for analysis of ultraviolet transparent cations.
J. Chromatogr. A. 1408 , 261-6, (2015) This paper describes the use of an anionic ion-pair reagent (IPR) to impove the ultraviolet (UV) detection and hydrophobic retention of polar and UV transparent cations. Anionic IPR added to the mobile phase forms an ion-pair with cations. Formation of the io... |

Inhibitory effect of collagen-derived tripeptides on dipeptidylpeptidase-IV activity.
J. Enzyme Inhib. Med. Chem. 29(6) , 823-8, (2014) The collagen tripeptide fragments Gly-Ala-Hyp, Gly-Pro-Ala and Gly-Pro-Hyp were generated by hydrolyzing collagen from pig-skin, cattle-skin, fish-scales and chicken-feet, respectively, with Streptomyces collagenase. Collagenase treatment increased the concen... |

Quantitation of Maillard reaction products in commercially available pet foods.
J. Agric. Food Chem. 62(35) , 8883-91, (2014) During processing of pet food, the Maillard reaction occurs, which reduces the bioavailability of essential amino acids such as lysine and results in the formation of advanced Maillard reaction products (MRPs). The aim of this study was to quantitate MRPs (fr... |
