    摘要: The present invention shows that DNA vaccine vectors can be improved by removal of CpG-N motifs and optional addition of CpG-S motifs. In addition, for high and long-lasting levels of expression, the optimized vector should include a promoter/enhancer that is hot down-regulated by the cytokines induced by the immunostimulatory CpG motifs. Vectors and methods of use for immunostimulation are provided herein. The invention also provides improved gene therapy vectors by determining the CpG-N and CpG-S motifs present in the construct, removing stimulatory CpG (CpG-S) motifs and/or inserting neutralizing CpG (CpG-N) motifs, thereby producing a nucleic acid construct providing enhanced expression of the therapeutic polypeptide. Methods of use for such vectors are also included herein.

    摘要: A fuel injector assembly for an internal combustion engine includes an injector body having a control valve in fluid communication with a source of fuel. A fuel nozzle assembly is employed to disperse fuel from the assembly. A high pressure fuel passage provides fluid communication between the control valve and the fuel nozzle assembly. The high pressure fuel passage has at least one end opening through the injector body and having an inner diameter. A shape memory alloy plug seals the open end of the fuel passage. The plug has a first diameter smaller than the inner diameter when inserted into the open end and a second diameter in sealing engagement with the inner diameter upon undergoing a metallurgical phase change from martinsite to austenite such that the plug generates a seal with the fuel passage. In addition, a method of making the fuel injector assembly employing a shape memory alloy plug to seal the high pressure fuel passage is also disclosed.
