Abstract:
... Identification and quantitative determination of analytes released from food contact materials (FCMs) is still an analytical challenge for scientists since neither chemical nor spectral databases nor analytical standards are available. Gas and liquid chromatography hyphenated to a variety of accurate mass analyzers based on the use of high-resolution have been used for this purpose. In this review ...

Subject:
antibiotic residues; antibiotics; food contamination; food production; foods; honey; liquid chromatography; minerals; quantitative analysis; sugars; tandem mass spectrometry; vitamins
Abstract:
... Honey is a complex and popular food product rich in sugars, vitamins, and minerals. Determination of antibiotic residues in honey is essential because the use of antibiotics has increased significantly in recent decades due to the growing need for food production. The concentration of antibiotic residues in honey is usually at trace levels, and thus liquid chromatography tandem mass spectrometry ( ...

Subject:
DNA; chromosomes; digestion; enzyme activity; enzymes; epigenetics; gene expression; ionization; liquid chromatography; mass spectrometry; nucleobases; pathogens; technology
Abstract:
... Four DNA bases are essential biochemical elements for coding heritable life blueprint. Meanwhile, organisms utilize modifying enzymes to post chemical groups on DNA bases to regulate gene expression, chromosome structures, and transposase activity, and to defense pathogens. The researches on the biochemical modifications of DNA bases are at the cutting edge of life sciences and chemical biology. U ...

Subject:
analytical chemistry; environmental assessment; humans; liquid chromatography; monitoring; pesticides; stereoselectivity; tandem mass spectrometry; toxicity
Abstract:
... Chiral pesticides can exert stereospecific toxicity in contaminated environmental compartments. Therefore, measuring pesticides at the enantiomeric level is essential to assess the risk posed to exposed organisms, including humans. In recent years, there has been rapid progress on the development and application of stereoselective liquid chromatography–tandem mass spectrometry (LC–MS/MS) methodolo ...
