20100080192 | CELL TIMING ACQUISITION IN A W-CDMA HARD HANDOVER - Cell timing is detected by first trying to detect a target handover cell through detecting a primary synchronization channel (P-SCH) followed by a common pilot channel (CPICH). If that fails, N number of retrials is performed using a full-window search on the CPICH. The full-window CPICH search is performed blindly, without any slot timing information from the P-SCH. Performance is improved while maintaining the benefits of faster acquisition methods in good channel conditions. The full-window search is more time consuming, but takes advantage of the stronger CPICH transmission. In good channel conditions, a mobile device can proceed quickly with the normal method of timing acquisition. With failure, the mobile device can switch to the longer search which has a higher probability of successfully completing the hard handover procedure. The overall effect is a higher success rate of hard handovers without a uniform increase of time spent in cell timing acquisition. | 04-01-2010 |

20110301108 | MATERIALS AND METHODS FOR SENSITIZING MULTIDRUG RESISTANT CELLS - Disclosed herein are materials and methods for sensitizing multidrug resistant cancer cells that express ABCG2 and related proteins members of a family of ATP-binding transporter superfamily that mediate drug efflux found in some types of multidrug resistant caner cells. A series of compounds, including (N-(4-chlorophenyl)-2-[(6-{[4,6-di(4-morpholinyl)-1,3,5-tri-azin-2-yl]amino}-1,3-benzothiazol-2-yl)sulfanyl]acetamide), specifically inhibits ABCG2 and can be used to boost the bio-avail-ability of one or more effective cancer killing drugs, making it possible to use certain widely used chemotherapeutic reagent to treat multidrug resistance cancers. Using these compounds in combination with chemotherapeutic drugs that are substrates for ABCG2 and related proteins may also find utility in treating cancer cells that are not currently identified as multi-drug resistant Additionally, these compounds appear to accelerate the intercellular degradation of ABCG2 and related proteins. They are not toxic to animals at levels at which they effect the activity of ABCG2 expressed in multi-drug resistant cancer lines. | 12-08-2011 |
