Stabilization Strategies for Catechins and Epicatechins: Recent Advances

Food Chemistry International, EarlyView.
Oxidation, epimerization, polymerization, and hydrolysis, driven by heat, pH, and oxygen, are pathways. Nano‐/microencapsulation maintains integrity with 70%–95% efficiency; biopolymer nanoparticles, starch/polysaccharide nanocarriers improve stability and dispersion. Lipid nanocarriers enhance bioavailability but raise oxidation risk.

Research Progress of Berberine in Kidney Disease: Targeting Mitochondria and Ferroptosis

iNew Medicine, EarlyView.
This figure illustrates the model‐specific renoprotective mechanisms of berberine (BBR) across three major kidney diseases. From left to right, the diagram shows that BBR targets distinct core pathways depending on the pathological context: in diabetic nephropathy (DN), BBR activates AMPK to improve mitochondrial energy metabolism; in acute kidney ...
