  • Publication number: 20070149592
    Abstract: This invention provides compositions, methods and kits for the diagnosis and treatment of cancers expressing a GLI polypeptide, and in particular a GLI1, GLI2 or GLI3 polypeptide. The invention provides small molecule compounds mimicking the transcriptional activation domain of a GLI polypeptide. The small molecule inhibitors of the invention specifically block the activator function of a GLI polypeptide, but not the repressor function of GLI3.

  • Publication number: 20070096327
    Abstract: A printed wiring board comprises a wiring substrate provided with at least one conductor circuit, a solder resist layer formed on the surface of the wiring substrate, covering the at least one conductor circuit, conductor pads formed on a part of the at least one conductor circuit exposed from respective openings provided in the solder resist layer for mounting electronic parts, and solder bumps formed on the respective conductor pads. Connection reliability and insulation reliability are easily improved by making the ratio (H/D) of a height H from solder resist layer surface the solder bump to an opening diameter of the opening about 0.55 to about 1.0 even in narrow pitch structure under the pitch of the opening provided in the solder resist layer of about 200 ?m or less.
