Thus, when the vehicle brake is removed, the compressor speed is high enough to provide enough air to the cathode, so that the stack can generate nearly immediate power. | 09-01-2011 |

20120035114 | INHIBITORS OF STAT3 AND USES THEREOF - Compounds which inhibit the activity of signal transducer and activator of transcription 3 (STAT3) are provided together with methods of making and using the same. The compounds are designed to bind to the SH2 domain of STAT3, preventing STAT3 from binding to receptors for interleukin-6 family cytokines, growth factors such as the platelet-derived growth factor, the epidermal growth factor, vascular endothelial growth factor, and other signaling molecules such as leptin. Blocking these interactions prevents STAT3 from being phosphorylated on Tyr705, which is required for the dimerization of STAT3, translocation to the nucleus, binding to STAT3 response elements on promotors, and transcription of genes. In addition to these activities, binding to the SH2 domain of STAT3 breaks up pre-formed dimmers, thereby preventing the transcriptional activity of the inhibitor. | 02-09-2012 |
