  • Patent number: 9474777
    Abstract: An extract of Graptopetalum paraguayense prepared by a method that includes: extracting a Graptopetalum paraguayense (GP) starting material with an alcoholic solvent to produce an alcoholic extract and a residue; separating the residue from the alcoholic extract; extracting the residue with an aqueous dimethyl sulfoxide (DMSO) solvent to produce a DMSO extract; subjecting the DMSO extract to ultrafiltration using a filter having a selected molecular weight cutoff; drying a fraction retained by the filter to obtain the extract of Graptopetalum paraguayense. Uses of an extract of Graptopetalum paraguayense for the treatment or prevention of liver fibrosis, hepatic cirrhosis, liver cancer, recurrence of liver fibrosis after surgery, or recurrence of liver cancer after surgery.

  • Patent number: 9136701
    Abstract: A high voltage discharge protective device for an RF device having a signal port, includes a blocking capacitor arranged at the signal port of the RF device, a circuit board for mounting the blocking capacitor, and a metal conductor grounded and partially bare. The blocking capacitor includes a main body and two leads connected to the main body and secured to the circuit board. The bottom portion of the main body is bare to form an exposed portion. The exposed portion is spaced apart from the circuit board to form an interval. The metal conductor is disposed within the interval and corresponds to the exposed portion of the blocking capacitor. When the passing voltage within the blocking capacitor reaches a predetermined value, the exposed portion of the blocking capacitor sparkly discharges to the metal conductor. An RF device is also provided.
