Bus scaling device
A scaling device or striper improves the lane efficiency of switch fabric. The striper controls or adjusts transfer modes and payload sizes of a large variety of devices operating with different protocols. The striper interfaces between network devices and the switch fabric, and the resulting switching system is configurable by a single controller. A source device sends a data packet to its corresponding striper for transmission across the switch fabric to a destination device. The corresponding striper parses the packet to determine its type and payload length, and divides the packet into numerous smaller segments when the payload length exceeds a predetermined length. The segments may be stored in the striper to adapt to the available bandwidth of the switch. The segments are sent across the switch fabric and reassembled at a destination striper. The packet as reassembled is forwarded to the destination device. |

TRPM-2 antisense therapy
It has now been determined that antisense therapy which reduces the expression of TRPM-2 provides therapeutic benefits in the treatment of cancer. In particular, such antisense therapy can be applied in treatment of prostate cancer and renal cell cancer. Addition of antisense TRPM-2 ODN to prostatic tumor cells in vivo is effective for delaying the onset of androgen independence. Thus, prostate cancer can be treated in an individual suffering from prostate cancer by initiating androgen-withdrawal to induce apoptotic cell death of prostatic tumor cells in the individual, and administering to the individual a composition effective to inhibit expression of TRPM-2 by the tumor cells, thereby delaying the progression of prostatic tumor cells to an androgen-independent state in an individual. Combined use of antisense TRPM-2 and taxanes synergistically enhances cytotoxic chemosensitivity of androgen-independent prostate cancer. In addition, it has also been found that antisense TRPM-2 has beneficial effect for other cancer types. Specifically, antisense TRPM-2 ODN enhances chemosensitivity in human Renal cell cancer, a normally chemoresistant disease with no active chemotherapeutic agent having an objective response rate higher than 10%. Radiation sensitivity is also enhanced when cells expressing TRPM-2 are treated with antisense TRPM-2 ODN. Thus, the antisense TRPM-2 ODNs can be used to enhance hormone sensitivity, chemosensitivity and radiation sensitivity of a variety of cancer types in which expression of TRPM-2 has been observed. |
