Extraction of boron from aqueous solutions using selective resins is important in a variety of applications including desalination, ultrapure water production, and nuclear power generation. Today's commercial boron-selective resins are exclusively prepared by functionalization of styrene-divinylbenzene (STY-DVB) beads with N-methylglucamine to produce resins with boron-chelating groups. However...

BACKGROUND RNA interference has promising therapeutic potential. However, safe and efficacious delivery systems are necessary for its application in the clinic. MATERIALS AND METHODS An oleic acid (OA) derivative of branched polyethylenimine (PEI, M.W. 2000 Da), PEI-OA, was synthesized and evaluated for small interfering RNA (siRNA) delivery in SK-HEP-1 liver cancer cells stably transfected w...
