  • Publication number: 20240066097
    Abstract: Embodiments of a composition provide a line of defense against SARS coronaviruses that complements vaccines. The composition may be taken orally, intravenously, nasally, or inhaled by a healthy person to prevent a SARS infection or by a sick person infected by a SARS coronavirus for treatment. The composition is configured for molecular pattern recognition based targeting of the SARS coronavirus spike (S) protein and activating an innate immune response. The composition includes a lectin component. The composition may also include an optional flavonoid component, an optional calcium component, or both.

  • Publication number: 20210369129
    Abstract: Central blood pressure parameters are monitored using a smart watch or smart band. A PPG sensor on the smart watch or smart band is adapted to sense blood perfusion in the finger (or lower wrist/radial artery) of the person wearing the smart watch or smart band. The PPG signal captures cardiovascular features which can be detected after proper filtering and processing. Signal processing, using the transfer function method, results in an un-calibrated central pressure waveform, which can be used to calculate various cardiovascular parameters or indicators of the parameters that are displayed on the smart watch or smart band. Digital signal processing can be implemented on the smart watch or smart band, on a smart phone, laptop or in the Cloud.

  • Publication number: 20190275168
    Abstract: The present disclosure provides methods for treating autosomal dominant diseases in a subject. In some aspects, the methods involve the use of a gene editing enzyme with a pair of unique guide RNA sequences that targets both mutant and wildtype forms of autosomal dominant disease-related gene for destruction in cells, and then supplying the cells with wildtype autosomal dominant disease-related gene cDNA which is codon modified to evade recognition by the guide RNAs. These methods are broadly applicable to any autosomal dominant disease.

  • Publication number: 20150098990
    Abstract: The present invention concerns methods and compositions that employ peptides that target dorsal root ganglion (DRG) neurons. In particular, the peptides are used to target therapeutic agents, such as proteins, liposomes, or viral particles comprising therapeutic polynucleotides, to one or more peripheral neuropathies or neuropathic pain, for example. In particular cases, the peripheral neuropathies or neuropathic pain is caused directly or indirectly by DRG neuronopathy.

  • Publication number: 20070210785
    Abstract: A multiple sensitivity stud sensing device for determining a location of objects behind a wall lining has a housing with a surface for moving over the wall lining. Within the housing are a capacitive sensor with first and second capacitances provided adjacent the surface and control circuitry. The control circuitry includes a detecting circuit connected to the sensor for providing a detection signal related to an imbalance between the first and second capacitances, a processor for receiving the detection signals signal and providing a display signal. A display is provided on the housing for indicating a location of an object behind the wall lining. The processor compares the detection signal to stored predetermined threshold values of detection signals associated with different wall lining thickness and displays a thickness value to the user.

  • Publication number: 20020197653
    Abstract: An in vivo assay system for identifying chemical compounds that inhibit or promote a biological event is described. Test compounds may be assayed for their ability to induce the expression of a reporter gene which subsequently leads to the production of a reporter gene product. Preferably the reporter gene product is secreted from the cell or is membrane permeable so that the product is readily detectable. The signal from the reporter gene is preferably amplifiable so that even minute changes in expression of the reporter gene are detectable. The present invention also provided combinatorial libraries for use in the inventive assay system.
