Laboratori de Botànica (UB), Facultat de Farmàcia i Ciències de l'Alimentació-Institut de Recerca de la Biodiversitat (IRBio), Unitat Associada al CSIC, Universitat de Barcelona, Av. Joan XXIII 27-31, Barcelona, Catalonia, 08028, Spain.
Background: Cannabis sativa L. (Cannabaceae) has been widely used by humans throughout its history for a variety of purposes (medicinal, alimentary and other uses). Armenia, with its rich cultural history and diverse ecosystems, offers a unique context for ethnobotanical research about traditional uses of Cannabis.

Background: Fungal pretreatment for partial separation of lignocellulosic components may reduce lignocellulose recalcitrance during the production of biofuels and biochemicals. Quantitative and qualitative modification of plant lignin through genetic engineering or traditional breeding may also reduce the recalcitrance. This study was conducted to examine the effects of combining these two approaches using three white rot fungi and mulberry wood with an altered lignin structure.

Background: Persistent and mobile organic compounds (PMOC) are of great concern for water quality and human health. The recent improvement and availability of high-resolution mass spectrometry in combination with liquid chromatography have widely expanded the potential of analytical workflows for their detection and quantitation in water. Given their high polarity, the detection of some PMOC requires alternative techniques to reversed-phase chromatography, such as hydrophilic interaction liquid chromatography (HILIC) and supercritical fluid chromatography (SFC).

Monounsaturated fatty acids (MUFA) are an important class of nutrients and are involved in lipid metabolism. The positions of the C=C bond and cis-trans isomerism have a significant influence on their physiological activity. However, simultaneously detecting these two structural properties has been challenging due to multiple isomers of MUFA.
