  • ?-synuclein expression inhibitor
    Patent number: 11234995
    Abstract: The present invention can provide a nucleic acid medicine which has a higher effect and a more prolonged effect of inhibiting the expression of ?-synudein can be provided. Disclosed is the oligonucleotide or a pharmacologically acceptable salt thereof, the oligonucleotide containing at least one nucleoside structure represented by Formula (I): (where each of Base and A are defined substituent or structure), can bind to an ?-synudein gene, has activity for inhibiting expression of the ?-synudein gene, and is complementary to the ?-synudein gene, and the oligonucleotide has a length of twelve to twenty bases.

  • Image forming apparatus capable of preventing the winding on the image carrier
    Patent number: 5321477
    Abstract: It has been discovered that a cause of a transfer member winding on an image carrier at the time of transfer is attributable to a discharge in a gap formed between a forward end of the image carrier and a transfer member transporter and is characterized in that the discharge in that gap is ineffectuated by being controlled. An image-forming apparatus capable of preventing not only the winding on the image carrier, but also the fouling of the forward end even when the transfer member is changed in size, is provided by controlling the discharge in the gap. The gap may be ineffectuated by being pressed physically using a guide, thereby preventing the discharge in the gap. As an alternative, the transfer charge amount is controlled in accordance with the position where the forward end of the image carrier passes the transfer element.
