A co-delivery system that can transport cancer related microRNAs and chemotherapeutics to their distinct targets in the tumors is an attractive strategy to eliminate tumor relapse in lung cancer therapy. In this study, we developed a dual-drug delivery system for an endogenous microRNA (miR-34a) and paclitaxel (PTX) for synergistic cancer therapy. PTX (a(More)
Successful anticancer chemotherapy requires targeting tumors efficiently and further potential to eliminate cancer stem cell (CSC) subpopulations. Since CD44 is present on many types of CSCs, and it binds specially to hyaluronic acid (HA), we tested whether coating solid lipid nanoparticles with hyaluronan (HA-SLNs)would allow targeted delivery of(More)
The concentrations of 10 polycyclic aromatic hydrocarbons (PAHs) were simultaneously measured for five times (July and November 1999-2002) in four water bodies of Hangzhou, China. To investigate possible sources of PAH contamination, sediments, soils, runoff water and atmospheric particles of the region were also analyzed for their PAH contents. The maximum(More)
