    摘要： A drug delivery system that includes a hydrogel formed from cyclodextrin and an amphiphilic copolymer that includes an A polymer block comprising a poly(alkylene oxide) and a B polymer block comprising a poly(hydroxyalkanoate), and a therapeutically effective amount of at least one therapeutic agent intimately contained within the hydrogel. In one preferred embodiment of the invention, the A polymer block is poly(ethylene oxide) (PEO) and the B polymer block is poly[(R)-3-hydroxybutyrate] (PHB), and the copolymer is the triblock ABA copolymer PEO-PHB-PEO. A method of synthesizing the amphiphilic triblock copolymer is also provided.

    摘要： FIG. 1 is a front, left and bottom perspective view of a toy tool box, showing my new design;
    FIG. 2 is a front, left and bottom perspective view thereof, in an alternate position;
    FIG. 3 is a front view thereof;
    FIG. 4 is a rear view thereof;
    FIG. 5 is a left side view thereof;
    FIG. 6 is a right side view thereof;
    FIG. 7 is a top plan view thereof; and,
    FIG. 8 is a bottom plan view thereof.
    The pattern shown on the surfaces of the toy tool box illustrates a wood grain appearance that is continuous throughout the surfaces on which it is shown.
    The shaded portions of the design are included to illustrate the color black.
