  • Patent number: 7651248
    Abstract: Provided is a lighting fitting intended to be mounted in a panel. The fitting includes a body in which a lamp may be mounted. The body includes one or more ventilation apertures which are sized and configured to allow heat generated by a lamp in the body to be adequately vented to the exterior of the body, but to inhibit the passage of fire from the interior of the body to the exterior of the body. The one or more ventilation apertures may be formed by a slot in the body. The one or more ventilation apertures may be configured so that when the fitting is installed in its intended orientation, an at least partially downward path is defined between the interior and exterior of the body of the fitting through the aperture.
    Type: Grant

  • Patent number: 6197754
    Abstract: The present invention provides methods and compositions for the suppression of oncogenic transformation, tumorigenesis and metastasis. The present invention discloses functional domains of E1A responsible for the suppression of transformation, and provides mini-E1A constructs that can be used for tumor suppression. The invention also discloses methods for the novel use of mini-E1A in combination with chemotherapeutic drugs and/or tyrosine kinase inhibitors.

  • Patent number: 5814315
    Abstract: Disclosed are methods and compositions for the suppression of expression of the neu oncogene, as well as suppression of neu oncogene-mediated transformation, tumorigenesis and metastasis. The method disclosed involves introduction of adenovirus early 1A gene (the E1A gene) products, or the large T antigen (the LT gene product), or both into affected cells. These products, which are preferably introduced by transfection of the E1A gene into affected cells, serve to suppress neu gene expression as measured by a reduction of p185 expression. Furthermore, the E1A gene products surprisingly serve to suppress the oncogenic phenotype, as indicated by a reduction in cell growth, growth in soft agar, as well as tumorigenic and metastatic potential in vivo. The inventors propose that E1A gene products, LT gene products or derivatives therefrom, may ultimately be employed a treatment modalities for neu-mediated cancers, such as cancers of the female genital tract and breast.

  • Patent number: 5641484

The method disclosed involves introduction of adenovirus early 1A gene (the E1A gene) products, so to large T antigen (the LT gene product), or both into affected cells. These products, which are preferably introduced by transfection of the E1A gene into affected cells, serve to suppress neu gene expression as measured by a reduction of p185 expression. Furthermore, the E1A gene products surprisingly serve to suppress the oncogenic phenotype, as indicated by a reduction in cell growth, growth in soft agar, as well as tumorigenic and metastatic potential in vivo.
