Recombinant expression and functional characterisation of regiospecific flavonoid glucosyltransferases from Hieracium pilosella L. [PDF]
, 2009 Five glucosyltransferases were cloned by RT-PCR amplification using total RNA from Hieracium pilosella L. (Asteraceae) inflorescences as template. Expression was accomplished in Escherichia coli, and three of the HIS-tagged enzymes, UGT90A7, UGT95A1, and

Sample Preparation and Separation of Lignans by Liquid Chromatography
Journal of Separation Science, Volume 49, Issue 5, May 2026.ABSTRACT Lignans are important phytochemicals found mostly in the resins of coniferous trees, but are also introduced into human diets through foods such as sesame seeds and extra‐virgin olive oil. They are pharmacologically interesting mainly because of their antioxidant activities, and they have also been shown to have cytotoxic and antimicrobial ...

Advanced Science, Volume 13, Issue 23, 23 April 2026.This study maps the spatiotemporal distribution of hydrophobic toxicants and endogenous metabolites in the developing placenta and fetus. By integrating mass spectrometry imaging with snRNA‐seq, we identify SR‐B1 as a key transporter driving early‐gestation xenobiotic transfer and reveal a critical exposure window associated with persistent fetal ...
