7 µm, 100 mm x 2.1 mm); mobile phase was 0.05% formic acid - acetonitrile (955 v/v); flow rate 0.1 mL/minute; gradient elution for 6 minutes; and detection at m/z 165.95 149 for O -methylguanine and m/z 136.9 110 for allopurinol. The present study has fulfilled the FDA validation parameter requirements. The method provides rapid, sensitive, and selective analysis of O -methylguanine using UPLC-MS/MS with a linear concentration range between 0.5-20 ng/mL. The present study has fulfilled the FDA validation parameter requiremen

As controls, nonconductive microspheres (PAGP@PDA, PAGP@PDA + Ag) were prepared similarly by using poly[(ethylalanine)(ethylglycyl)]phosphazene (PAGP). By co-implanting these microspheres with S. aureus into rat calvarial defects, among them, it was determined that the PATGP@PDA + Ag microspheres achieved the most abundant neo-bone formation, benefiting from their antibacterial, antioxidant and osteogenic activities. These results revealed that AgNPs loaded scaffolds made of conductive polyphosphazenes were promising for t
