  • Patent number: 11896715
    Abstract: The present invention relates to an in-vivo bulking agent which can be used as a medicinal agent for prevention or treatment of at least one disease selected from the group consisting of urinary incontinence, fecal incontinence, and gastroesophageal reflux or as a filler for use in a plastic surgery procedure, and to a preparation method therefor. The in-vivo bulking agent can exhibit a bulking effect when injected into the body and particularly, is highly biocompatible because a first composition in which silicone particles are coated with a zwitterionic polymer having a surfactant property is introduced into a second composition, whereby the bulking agent can inhibit inflammatory reactions in vivo.
    Type: Grant

  • Patent number: 9542899
    Abstract: A method of driving a display panel includes applying gate signals to gate lines of the display panel that extend in a first direction. A plurality of data lines extends in a second direction perpendicular to the first direction. Pixels are defined by an intersection of the gate lines and the data lines. Common electrode contact pixels are provided, in which a common electrode is contacted with a gate electrode extruded from the gate line. A data signal having a first polarity and a data signal having a second polarity, inverse to the first polarity, are applied to an equal number of the common electrode contact pixels.

  • Patent number: 7018820
    Abstract: Disclosed is a method of removing residual enzymes when microencapsulating enzymes, and more particularly, for inactivating enzymes remaining in an uncapsulated form during microencapsulation of enzymes by treating dispersion fluid of microcapsules containing enzymes with ozone, together with removal of microorganisms harmful to human beings, where the ozone treatment is conducted for 1–10 min with 1–10 ppm of ozone generated from a UV lamp in a range from 150 to 200 nm wavelength.
