Open AccessUntargeted metabolomics unveil alterations of biomembranes permeability in human HaCaT keratinocytes upon 60 GHz millimeter-wave exposure
A joint metabolomic and lipidomic workflow is used to account for a potential effect of millimeter waves (MMW) around 60 GHz on biological tissues. For this purpose, HaCaT human keratinocytes were exposed at 6...

Chapter
Analysis of Lichen Metabolites, a Variety of Approaches
Lichens produce secondary metabolites which have been first considered as a chemical support fully involved in lichen taxonomy. As a consequence, analytical methods were developed and applied to these organism...
