    摘要: In general, this disclosure is directed to signal processing based methods to reject oversensing due to electromagnetic interference or other noise without compromising tachyarrhythmia detection sensitivity. A method comprises sensing a signal indicative of cardiac activity, detecting a cardiac event based on the signal, determining a count of fluctuations of the signal within a window between the detected cardiac event and a next cardiac event, and determining whether noise is present in the signal based on the count.

    摘要: An implantable medical device uses an implantable sensor for acquiring a physiological signal that is received by a digital signal processor. The digital signal processor is a multi-channel signal processor including a first signal processing channel having a first sensitivity for sensing the physiological signal and a second signal processing channel having a second sensitivity different than the first sensitivity for sensing the physiological signal.

    摘要: The present invention relates to the diagnosis and treatment of cancer, and in particular breast cancer. Specifically, in some embodiments the invention relates to methods of diagnosing cancer, and in particular breast cancer, using an antibody specific for a gene product that localizes selectively to the endoplasmic reticulum of the cancer cell(s). In some embodiments, the invention relates to methods of treating cancer, and in particular breast cancer, by administering a composition comprising an RNA interference sequence (e.g., shRNA, RNAi and/or siRNA molecule) characterized by an ability to inhibit an mRNA molecule, which mRNA molecule is encoded by the C43 gene (SEQ ID NO: 1). The invention additionally relates to methods for detecting cancer cells by detecting reduced methylation of the C43 promoter, and methods for reducing cancer metastasis by using demethylation inhibitors that result in increased methylation of the C43 promoter. The invention additionally relates to an in vitro 3-dimensional assay for detecting migrating cells, identifying test agents and/or nucleotide sequences that alter cell migration.
