  • Publication number: 20070166284
    Abstract: The invention provides a method for treating cancer in a human comprising administering to the human a dose of a pharmaceutical composition comprising (i) a pharmaceutically acceptable carrier and (ii) an adenoviral vector comprising a nucleic acid sequence encoding TNF-? operably linked to a promoter, wherein the dose comprises about 1×107 to about 4×1012 particle units (pu) of replication-deficient adenoviral vector, at least once in a therapeutic period comprising up to 10 weeks, whereby the cancer in human is treated. The invention further provides a method of treating a human for multiple tumors, wherein the method comprises contacting a first tumor with a dose of the pharmaceutical composition at least once in a therapeutic period comprising up to about 10 weeks, whereby the human is treated for the first tumor and one or more additional tumors.

  • Patent number: 7199048
    Abstract: Methods and structures are provided for conformal lining of dual damascene structures in semiconductor devices that contain porous or low k dielectrics. Features, such as trenches and contact vias are formed in the dielectrics. The features are subjected to low-power plasma predeposition treatment to irregularities on the porous surfaces and/or reactively form an permeation barrier before a diffusion barrier material is deposited on the feature. The diffusion barrier may, for example, be deposited by CVD using metalorganic vapor reagents. The feature is then filled with copper metal and further processed to complete a dual damascene interconnect. The plasma predeposition treatment advantageously reduces the amount of permeation of the metalorganic reagent into the interlayer dielectric.
