Abstract Cutaneous wounds are prompt to be contaminated by bacteria, but the clinical benefits of applying antibiotics and antiseptics in wound management have not been proven. Statins 3‐hydroxy‐3‐methylglutaryl‐coenzyme A ( HMG‐CoA ) reductase inhibitors commonly used lower cholesterol levels. Studies indicated that statins, especially simvastatin, promote healing experimental models. As Staphylococcus aureus is one most important microorganism responsible for infections, aims this study...

Disc-shaped bicelles are formed by mixing long-chain lipids with short-chain at suitable molar ratios and they have a relatively uniform size, typically around few tens of nanometers in diameter. Different from the formulated cationic or anionic liposome–DNA complexes, which used as nonviral vectors for improving transfection efficiency gene therapy, novel way packing DNA can be developed using much smaller disc-like bicelles. We demonstrate that lipid bicelle-ion–DNA (AB–DNA) complexes help...
