Three novel flavonols, myricetin-3'-O-(6"-p-coumaroyl)glucoside and two epimeric macrocyclic derivatives, as well as the known myricetin-3-O-rhamnoside and pentagalloyl glucose, have been isolated from the wild water lily Nymphaea lotus L. and identified using 2D NMR. This is the first report of such a macrocycle from any source.

Abscisic acid (ABA) mediated stomatal closure is a highly effective mode of active stomatal regulation under drought stress. Previous studies on stomatal regulation have primarily focused on the leaves of vascular plants, while research on the stomatal behavior of bulbous plants remains unknown. In addition, ABA-induced stomatal regulation in bulbs has yet to be explored.

Understanding the intricate dynamics of sediment-mediated microbial interactions and their impact on plant tissue preservation is crucial for unraveling the complexities of leaf decay and preservation processes. To elucidate the earliest stages of leaf preservation, a series of decay experiments was carried out for three months on Nymphaea water lily leaves in aquariums with pond water and one of three distinctly different, sterilized, fine-grained substrates-commercially purchased kaolinite clay or fine sand, or natural pond mud. One aquarium contained only pond water as a control.

Atrial fibrillation leads to severe diseases such as heart failure and strokes. While catheter ablation is prevalent for the treatment, existing techniques hardly can achieve both tissue selectivity and ablation uniformity. Here, we propose a bioinspired strategy for balloon-based pulsed field ablation (PFA) systems based on "flounder" electrodes.

Protein encapsulated fat (PEF) blends are routinely used for manufacturing calf milk replacers (MR). The use of PEF blends improves fat mixability to ensure MR when mixed and fed as a homogenous solution for neonatal calves. A new alternative PEF based on choice white grease (CWG) has been developed to improve its mixability and solubility to ensure a homogenous MR solution.

Cadmium oxide nanoparticles (CdO-NPs) play an important role in health applications due to their antibacterial properties. However, ecotoxicological investigations of these NPs and their adverse effects on aquatic organisms are necessary to protect the environment. Zebrafish is widely used as a model organism to explore toxic effects at multiple levels of integration.
