Synthesis and application of alginate@CuFe2O4 polymeric spheres in 17‐β‐estradiol adsorption processes in Amazonian rivers

Polymer International, EarlyView.
Magnetic alginate beads, functionalized with copper ferrite, effectively remove 17‐β‐estradiol from Amazonian water, exhibiting optimized 238.65 μg g−1 capacity, fast 40 min kinetics, easy recovery, and successful remediation. Abstract The presence of endocrine‐disrupting compounds, such as 17‐β‐estradiol, in aquatic ecosystems poses a significant ...

Female Melanostoma hoverflies pollinate Cypripedium yatabeanum through a Paphiopedilum‐like floral trap

PLANTS, PEOPLE, PLANET, EarlyView.
Conserving rare plants requires understanding the ecological interactions that enable their reproduction. Although most studied Cypripedium species are pollinated by bees, the pollinators of many slipper orchids remain undocumented. We show that Cypripedium yatabeanum is pollinated by female aphidophagous hoverflies despite sharing broadly similar ...

UV mutagenesis‐enhanced Streptomyces nogalater produces a novel streptothricin‐like compound with strong activity against cabbage soft rot

Pest Management Science, EarlyView.
UV mutagenesis of Streptomyces sp. KRA0514‐6 yielded HL‐3, a novel streptothricin‐like compound (C17H29N7O8) with N‐methylglycine replacing β‐lysine, achieving 100% cabbage soft rot control at >1 ppm concentration. Abstract BACKGROUND A total of 1000 soil‐derived actinomycetes were isolated and screened for antibacterial activity against Pectobacterium

A Water Soluble Polymer as a Working Structural Model for Humic Acids: H-binding and Spectroscopic Properties

, 2008
HA occur ubiquitously in terrestrial and aquatic environments, indicating that many precursors and several formation pathways exist. Distinguishing among these pathways has been difficult because individual scientists have tended to concentrate their ...

Magnoflorine Ameliorates MASH in Mice Fed a High‐Fat and High‐Fructose Diet by Promoting AMPK‐Mediated Lipophagy and Fatty Acid Oxidation

Phytotherapy Research, EarlyView.
Magnoflorine ameliorates metabolic dysfunction‐associated steatohepatitis by promoting AMPKα‐mediated lipophagy and fatty acid oxidation. ABSTRACT Emerging as a significant clinical burden, metabolic dysfunction‐associated steatohepatitis (MASH) continues to challenge global healthcare systems due to limited effective interventions.
