  • Patent number: 6541619
    Abstract: The present invention provides a genetically engineered fusion protein consisting of hEGF that is internalized inside of the cells after tracing down the cancer cells expressing hEGF receptors and human angiogenin that is cytotoxic by degrading ribonucleotide upon internalization, a process for preparing a fusion protein in a large quantity by transforming E. coli with the expression vectors containing the gene encoding the fusion protein, and pharmaceutical application of the fusion protein as an anticancer agent. All components of the fusion protein form no antibodies and exhibit no immunotoxicity since they are derived from human. Each component alone is inactive to the cancer cells, however, once they are fused together, they kill the cancer cells selectively with a difference of 1000 fold in IC50 in spite of its low molecular weight. Therefore, the fusion protein of the present invention is capable of treating the cancer expressing hEGF receptors at high level without showing toxicity.

  • Patent number: 5375937
    Abstract: An album includes first and second shells hingedly connected together and defining a storage cavity therebetween. A plurality of leaves for mounting pictures are connected to the album and held in the storage cavity between the shells. Retaining members are provided on each of the shells so that, in the open position of the album, a portion of the leaves will be held against one of the shells and another portion of the leaves will be held against the other one of the shells. A cover over the exterior of the shells provides the album with a soft, cushioned feel. The album stores pictures securely for travel, yet may be used as a picture frame when opened and set on end.
