摘要： Methods and systems provide for operating a modem receiver such as an ADSL modem receiver. As incoming data signals are received, a decoding scheme is selected from a plurality of decoding schemes based on a predetermined downstream data rate. In one approach a soft receiver architecture of an ADSL modem is able to select between relatively complex decoding schemes and relatively simple decoding schemes based on signal-to-noise ratio (SNR).

摘要： Methods for determining the responsiveness of a Met-related cancer in a subject to treatment with a Met inhibitor. Kits for performing the disclosed methods are also provided. The present invention also provides a method of treating glioblastomamultiforme (GBM) in a subject in need thereof, the method comprises administering a therapeutically effective dose of a Met inhibitor in combination with a therapeutically effective dose of a epithelial growth factor receptor (EGFR) inhibitor.

摘要： Geldanamycin derivatives that block the uPA-plasmin network and inhibit growth and invasion by glioblastoma cells and other tumors at femtomolar concentrations are potentially highly active anti-cancer drugs. GA and various 17-amino-17-demethoxygelddanamycin derivatives are disclosed that block HGF/SF-mediated Met tyrosine kinase receptor-dependent uPA activation at fM levels. Other ansamycins (macbecins I and II), GA derivatives, and radicicol required concentrations several logs higher (≧nM) to achieve such inhibition. The inhibitory activity of tested compounds was discordant with the known ability of drugs of this class to bind to hsp90, indicating the existence of a novel target(s) for HGF/SF-mediated events in tumor development. Methods of using such compounds to inhibit cancer cell activities and to treat tumors are disclosed. Such treatment with low doses of these highly active compounds provide an option for treating various Met-expressing tumors, in particular invasive brain cancers, either alone or in combination with conventional surgery, chemotherapy, or radiotherapy.
