LaFeO3-δ nanoparticles were prepared by citric sol-gel method, which show weak ferromagnetic (FM) behavior at room temperature with magnetization of 0.11emu/g at 10kOe. XPS indicates that La is rich at the surface region and Fe ions are in the mixed state of Fe3+ and Fe4+. The double exchange interaction of Fe3+-O2−-Fe4+ between neighboring Fe3+ and Fe4+ ions would result in strengthened FM shell...
In traditional Chinese medicine, the flower of Pueraria lobata (Puerariae Flos) has been used in therapy to counteract the problems associated with alcohol drinking and liver injury. In this study, we investigated the hepatoprotective effects and its mechanisms of tectoridin, an isoflavone glycoside from the flower of P. lobata (Willd.) Ohwi. Ethanol (5g/kg) was given orally every 12h for a total...
