Protective Role of Saponins Against Diabetic Perturbations and Complications in Rats
Natural Product Communications, 2007 Trigonella hamosa saponins (SS) were purified using Sephadex LH-20. The effects of SS on diabetes, lipid profiles and glucose homeostasis were investigated by supplementation of the diet of rats with SS, which countered the adverse, harmful effects of ...

Engineering an Artificial Metalloenzyme for Efficient Photo‐Enzymatic CO2 Conversion
Advanced Science, EarlyView.We built a light‐driven artificial metalloenzyme by covalently conjugating formate dehydrogenase (FDH) with a tailored rhodium complex (Rh‐L6) to overcome spatial‐separation‐limited electron transfer. This integration boosts NADH regeneration and CO2 conversion, giving 2.31‐fold higher formate yield than physical mixtures, due to a narrowed bandgap and

Cationic‐Hydrophilic Di‐Block Copolymers: Surface‐Shielded Vectors for Gene Delivery
Journal of Polymer Science, Volume 63, Issue 6, Page 1419-1432, 15 March 2025.This study develops synthetic polycationic di‐block carriers for nucleic acid (NA) delivery in gene therapy. Consisting of a cationic block and a hydrophilic block, these carriers efficiently form complexes with NAs and shield them with a protective bioinert layer, enhancing stability during circulation in the bloodstream while reducing undesirable ...

Small, EarlyView.Polyion complex micelles composed of blends of ABA and AB block copolymers can form coacervates with a hexagonally packed cylinder nanostructure after heating. The resulting coacervates can release the micelles under physiological conditions in a zero‐order kinetics, possessing cargo proteins.
