Publication number: 20120244160Abstract: This disclosure describes a relevant etiology of cancer and a novel anti-cancer therapeutic strategy, based on the discovery that a protein named serine protease inhibitor (SPIK/SPINK/PSTI) was up-regulated by hepatitis B and C virus infections consequently suppressing the cell apoptosis. Accordingly, the present disclosure provides, inter alia, an inhibitor of SPIK and/or a technology of suppression of over-expression of SPIK in cells. The inhibitors include: 1) chemical compounds, which can inhibit SPIK transcripts, protein activity, and gene expression, 2) SPIK siRNA (RNAi gene silence or dsRNA of SPIK, 3) DNA anti-sense and anti-SPIK antibody. Further, this disclosure provides methods of using the inhibitor as an anti-cancer agent to re-instate cancer cell apoptosis (e.g., serine protease dependent cell apoptosis).Type: ApplicationFiled: May 25, 2012Publication date: September 27, 2012Applicant: PHILADELPHIA HEALTH & EDUCATION CORPORATION, D/B/A Drexel University College of MedicineInventors: Xuanyong Lu, Timothy Block

Publication number: 20060104265Abstract: Provided are a method, system, and program for configuring shared devices over a fabric. A module in a first processing complex configures a first part of a fabric enabling communication with a set of devices accessible through the first part of the fabric. The module detects a located device accessible through a second part of the fabric, wherein a second processing complex is designated to configure the second part of the fabric and the located device. The module determines whether the second processing complex is available in response to detecting the uninitialized device. The module passes to a device driver in the first processing complex an uninitialized property for the located device. The device driver requests the module to configure the second part of the fabric to enable access to the located device over the second part of the fabric in response to determining that the located device has the uninitialized property.Type: ApplicationFiled: November 12, 2004Publication date: May 18, 2006Inventors: Timothy Block, Yu-Cheng Hsu, John McCauley, Sean Riley, William Sherman, Cheng-Chung Song

Publication number: 20050246570Abstract: An apparatus, program product and method support the dynamic modification of cluster communication parameters such as a fragmentation size parameter through controllably deferring the processing of a requested fragmentation size change in a source node until after receipt an acknowledgment message for at least one unacknowledged message sent by the source node to a plurality of target nodes. By controllably deferring such processing until it is confirmed that any such previously-unacknowledged messages sent by a source node have been received by any target nodes, synchronization between the source node and the target nodes may be obtained, and a fragmentation size change may occur in a coordinated fashion such that future messages from the source node to the target node will be processed by both the source and the target nodes using the modified fragmentation size parameter.Type: ApplicationFiled: June 16, 2005Publication date: November 3, 2005Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Timothy Block, Kiswanto Thayib

Publication number: 20050025121Abstract: A method and system for communication in a system area network (SAN) data processing system are described. The SAN includes a plurality of interconnected nodes that each have at least one port for communication. To avoid communication-induced errors that may arise, for example, if multiple nodes share the same node ID, the port of a node in the SAN is marked as “fenced” to prevent transmission of packets of a first traffic type while permitting transmission of packets of a second traffic type. The marking of the port may be recorded, for example, in a configuration register of the port. While the port is fenced, only packets of other than the first traffic type are routed via the port. In one preferred embodiment, the second traffic type represents SAN configuration traffic, and the first traffic type represents non-configuration traffic.Type: ApplicationFiled: September 3, 2004Publication date: February 3, 2005Applicant: International Business Machines CorporationInventors: Timothy Block, Richard Booth, David Engebretsen, Thomas Sand, Kenneth Valk
