| 20090180966 | Cancer cell diagnosis by targeting delivery of nanodevices - Macromolecular contrast agents for magnetic resonance imaging are described. Biomolecules and their modified derivatives form stable complexes with paramagnetic ions thus increasing the molecular relaxivity of carriers. The synthesis of biomolecular based nanodevices for targeted delivery of MRI contrast agents are described. Nanoparticles (NP) have been constructed by self-assembling of chitosan (CHIT) as polycation and poly-gamma glutamic acids (PGA) as polyanion. NP's are capable of Gd-ion uptake forming a particle with suitable molecular relaxivity. Folic acid (FA) is linked to the NP's to produce NP-FA bioconjugates that can be used for targeted in vitro delivery to a human cancer cell line. | 07-16-2009 |

| 20120103872 | METHOD FOR REDUCING MERCAPTANS IN HYDROCARBONS - A method for reducing mercaptan concentration in a crude oil is disclosed. The method comprises contacting the crude with a treating solution comprising a hypochlorite solution, whereby the mercaptan sulfur is oxidized and converted to at least one sulfur oxoacid or salt thereof, yielding a treated crude oil having less than 50 ppm mercaptan sulfur and residual organic chloride. The treated crude oil containing residual organic chloride is brought in contact with a caustic solution at a molar ratio of caustic to chloride of 0.1:1 to 50:1, generating an upgraded crude oil with less than 10 ppm organic chloride. In one embodiment, the spent treating solution is recycled to form a regenerated hypochlorite stream for use in the treatment solution. | 05-03-2012 |
