PYRROLIZIDINE ALKALOIDS: THE BOTANICAL ORIGIN OF POLLEN COLLECTED DURING THE FLOWERING PERIOD OF ECHIUM VULGARE AND THE STABILITY OF PYRROLIZIDINE ALKALOIDS IN BEE BREAD

Previous studies have shown that pollen products sold as nutritional supplements and used in apitherapy may contain toxic pyrrolizidine alkaloids (PAs) if bees collect pollen from PA-containing plants, such as Echium vulgare.In this study, the botanical origin of pollen from two observation sites was studied.Despite a high PA content in pollen samp

Abstract The Nuclear receptor 4A (NR4A) subfamily, which belongs to the nuclear receptor (NR) superfamily, has three members: NR4A1 (Nur77), NR4A2 (Nurr1) and NR4A3 (Nor1).They are gene kaiser copy stands regulators with broad involvement in various signaling pathways and human disease responses, including autophagy.Here, we provide a concise overv
