  • Patent number: 7319033
    Abstract: Replication-competent adenovirus vectors specific for cells which allow a probasin transcriptional response element (PB-TRE) to function, such as cells which express the androgen receptor (AR), and methods of use of such viruses are provided. These viruses comprise an adenoviral gene under control of a transcriptional regulatory portion of a PB-TRE, which is in turn dependent upon AR expression. The gene can be, for example, a gene required for viral replication or the adenovirus death protein gene (ADP). The viruses can also comprise at least one additional adenoviral gene under control of at least one additional prostate-specific transcriptional response element, such as that controlling prostate-specific antigen expression (PSA-TRE). Thus, virus replication can be restricted to target cells exhibiting prostate-specific gene expression, particularly prostate carcinoma cells.

  • Publication number: 20060214167
    Abstract: In a process for producing a TFT display, a polysilicon layer is patterned to define a first and a second TFT regions. A first doping material is implanted into a first exposed portion in the first TFT region to define a first doped region and a first channel region, and implanted into a second exposed portion in the second TFT region to define a second doped region and a second channel region. A second doping material is implanted into a third exposed portion smaller than the first exposed portion to form first source/drain regions and simultaneously define a first LDD region in the first TFT region. A first and a second gate structures are formed over the first and the second channel regions, respectively. In a certain direction, the first gate structure is longer than the first channel, and the second gate structure isn't longer than the second channel region.
