  • Patent number: 7183263
    Abstract: Linear polyethylenimine was modified with sterols, such as cholesterol, in three different geometries: linear shaped (L), T-shaped (T), and a combined linear- and T-shaped (LT), to result in linear polyethylenimine-sterol conjugates. These conjugates were mixed with nucleic acids to form complexes for delivery of the nucleic acids into cells. Mammalian cells transfected with these complexes showed protein expression levels higher than linear polyethylenimine alone, and twice that of branched polyethylenimine, but without any significant loss in cell viability. Methods of making these compositions and methods of using them for gene delivery are also described.

  • Patent number: 7179381
    Abstract: A method for treating contamination in subsurface formations includes fracturing the soil to produce a network of fractures in the formation and simultaneously injecting a slurry containing an optional proppant and a solid-phase or nonaqueous-phase treatment agent into the network of fractures. The proppant is for keeping the fractures open, and the treatment agent accelerates conversion of the contaminants into immobile or less toxic forms. Chitin is an illustrative solid-phase treatment agent, which functions as an electron donor for anaerobic reductive dechlorination mediated by dechlorinating bacteria.

  • Patent number: 7171703
    Abstract: A track assembly for flexible pool covers. The track assembly includes track members, and securing pieces for being secured to the pool deck and for splicing the track members together in an end-to-end series. The securing pieces are designed to reside beneath, and to be concealed by, the tracking members. The securing pieces may be attached to a pool deck with fasteners, after which the track members may be snapped downwardly onto the securing pieces to thereby secure the track members to said securing pieces. The track members conceal the securing pieces, and the fasteners that secure the securing pieces to the pool deck, thereby providing an aesthetic appearance of continuous tracking uninterrupted by fasteners, fastener holes, or other through holes. This arrangement prevents the fasteners from coming loose and posing a risk to barefooted bathers, because the upward movement of the fasteners is inhibited by the track members that reside above the fasteners.
