To improve the bioavailability and targeting effect to hepatic cells of volatile oil from Atractylodes macrocephala Koidz, the volatile oil was incorporated into liposomes by a improved process of rapid expansion of supercritical solutions (RESS). In this process, the liposomal materials and the volatile oil were dissolved in the mixture of supercritical carbon dioxide (SC-CO2)/ethanol and then the...
Soil with combined pollutants of phenanthrene (phe) and lead (Pb) or with either of them were composted in three laboratory reactors to study the degradation of phe and the reduction of the solubility and bioavailability of Pb during composting. The change of the residual ratio of phe, the transformation of Pb, and the parameters of composting including pH and volatile solids (VS) were investigated...
A major limitation of land application of compost is the potential heavy metal pollution, and lead (Pb) has been recognized as one of the most hazardous heavy metal. To reduce the hazards of Pb to the compost application, composting of Pb- polluted wastes by inoculating white-rot fungi was investigated. The parallel waste composting with no inoculants was performed as control. The form distribution...
Realgar, one of mineral drugs in Chinese traditional medicines has attracted an increasing attention because of its prominent anti-tumor effect. However, new challenges for improving its bioavailability has to be faced. Our previous studies have demonstrated that realgar nanoparticles may provide a less toxic agent for anti-neoplasia by suppressing angiogenesis. In the present study, we improved milling...
