  • Patent number: 11137429
    Abstract: A signal measurement device and method are provided for receiving an RF input signal using frequency sweeping. The method includes determining RMS power levels of a noise floor of the signal measurement device at respective frequencies from a start frequency to a stop frequency of a swept frequency range; determining values of resolution bandwidths corresponding to the frequencies, the values of the resolution bandwidths being inversely proportional to the RMS power levels of the noise floor at the respective frequencies; performing frequency sweeping from the start frequency to the stop frequency to receive the RF input signal at the signal measurement device; and implementing the determined values of the resolution bandwidths corresponding to the frequencies while performing the frequency sweeping.

  • Publication number: 20200362314
    Abstract: Human induced pluripotent stem cell derived cardiomyocytes (hiPSC-CMs) are a powerful tool for studying cardiovascular disease and drug screening. However, most current methods of cell culture result in cells resembling fetal myocardium, which is potentially problematic as most forms of cardiovascular disease occur in the adult heart. Disclosed systems and methods include culturing cells in fatty-acid based medium and on patterned growth to produce hiPSC-CMs which mimic adult cardiomyocytes and display a similar hypertrophic response as is observed in cardiovascular disease.

  • Publication number: 20110171196
    Abstract: The present invention provides for methods of treating and cardiac hypertrophy, heart failure, dilated cardiomyopathy or hypertension comprising the use of CaMKII-HDAC binding domains. The present invention discloses not only the fact that CaMKII binds to HDAC4 at a specific site, but that HDAC4 may dimerize with other HDACs. Both events can lead to export of HDACs from the nucleus to the cytoplasm, an event associated with the development of heart disease. Thus the methods of treatment and the screening methods of the present invention are novel attempts to prevent, treat or identify therapies for cardiac hypertrophy, heart failure, dilated cardiomyopathy or hypertension.
