  • Publication number: 20090281033
    Abstract: The invention relates to the field of drug development against acute radiation injury caused by exposure to high-energy electromagnetic waves (X-rays, gamma rays) or particles (alpha particles, beta particles, neutrons). To date, there is no effective drug to ameliorate radiation injury after accidental exposure to ionizing irradiation. The invention provides a method of treating radiation injury of a subject in need thereof comprising administering to the subject a peptide, or functional analogue or derivative thereof, of smaller than 30 amino acids. Furthermore, the invention provides use of a peptide, or functional analogue or derivative thereof, of smaller than 30 amino acids for the production of a pharmaceutical composition for the treatment of a subject suffering from or believed to be suffering from radiation injury. In particular, the invention provides anti-radiation peptides having a dose reduction factor (DRF) against acute gamma irradiation of at least 1.

  • Patent number: 7599371
    Abstract: A first router receives an original IS-634 standard frame formatted message over an A-bis interface from a base transceiver station. The first router identifies header information bits in the message for compression. The first router suppresses selected ones of the identified header information bits and encapsulates the message into a packet. A second router receives the packet from the first router and extracts the message from the packet. The second router reconstructs the selected ones of the header information bits that were suppressed by the first router. The second router regenerates the original IS-634 standard frame formatted message and transports the message to a base station controller over the A-bis interface.

  • Publication number: 20090227505
    Abstract: Where it was generally thought that the smallest breakdown products of proteins had no specific biological function on their own, it now emerges that the body may utilize the normal process of proteolytic breakdown to generate important compounds such as gene-regulatory compounds. For instance, certain short breakdown products of hCG (i.e., short peptides which can easily be synthesized, if needed modified, and used as a pharmaceutical composition) exert a major regulatory activity on pro- or anti-inflammatory cytokine cascades that are governed by a family of crucial transcription factors, the NF-?B family, which generally regulate the expression of genes involved in the body's immune response.

  • Patent number: 7283404
    Abstract: A content addressable memory (CAM) system is disclosed including a dual mode cycle boundary latch (CBL). The CBL includes a master latch coupled to a slave latch. The CBL operates in a high speed functional mode and a lower speed test mode. In the high speed functional mode, input data bypasses the master latch and transports directly to the CBL output via the slave latch. The CBL effectively removes the master latch from the circuit in the high speed functional mode. However, in the lower speed test mode, input test data travels via both the master and slave latches to the CBL output.

  • Patent number: 7167385
    Abstract: A CAM system is disclosed in which compare data, for example an address translation request, is provided as input search data to a search line generator. The search line generator presents search line input data, through a buffer, to CAM and RAM array systems that include dynamically precharged and evaluated memory cells. Timing sequences in the CAM system are controlled by a series of individually triggered one shot pulse generators. The one shot pulse generators control the timing of CAM system activities, for example the precharge of CAM subsystems, so that these activities are staggered in time. This timing approach improves power consumption and evaluation time within the CAM system. By distributing precharging activities in time throughout the CAM cycle, current peaking during the CAM cycle is reduced. The CAM system latches results in an output latch that is controlled by a one shot pulse generator.
