  • Publication number: 20070166415
    Abstract: The present invention provides a new method for extracting Homoharringtonine (HHT) by culture cells or culture plant tissues. Also, disclosed are methods of obtaining HHT from semi-synthesis and biosynthesis. The present invention disclosed that HHT combined with some botanical drugs could induce cancer cells to resemble normal cells. To add some botanical drugs combined with HHT can significantly increase anticancer effects of HHT. These drugs include Matrine (MAT), Guanzhongsu (GU), Maidongsu (MU), and Indirubin (IND). The experimental data showed that above drugs have strong synergisms effects for treating leukemia and other cancer cells and more safe.

  • Patent number: 6860585
    Abstract: A printer with a carriage adapted to receive a printhead capable of printing an ink at an effective nozzle density along a medium advance axis. The printhead includes a plurality of substantially parallel columnar arrays of nozzles, each columnar array having an actual nozzle density along the medium advance axis less than the effective nozzle density. An alignment structure in the carriage orients the printhead to print at the actual nozzle density along the medium advance axis such that individual nozzles in different ones of the columnar arrays can deposit ink on a print medium in a row substantially orthogonal to the medium advance axis.
