  • Publication number: 20210163934
    Abstract: The object of the present invention is to provide a nucleic acid agent that can be efficiently delivered to the nervous system, particularly the central nervous system to which the BBB mechanism prevents drug delivery, and can produce an antisense effect on a target transcriptional product at the delivered site, and a composition comprising the same. Provided is a double-stranded nucleic acid complex formed by annealing a first nucleic acid strand capable of hybridizing to part of a target transcriptional product, and has an antisense effect on the target transcriptional product, to a second nucleic acid strand comprising a base sequence complementary to the first nucleic acid strand, and is bound to tocopherol or an analog thereof, cholesterol or an analog thereof, or a substituted or unsubstituted C1-30 alkyl group, a substituted or unsubstituted C2-30 alkenyl group, or a substituted or unsubstituted C1-30 alkoxy group.

  • Patent number: 10916597
    Abstract: A display device according to an embodiment of the present invention includes: a flexible substrate having a plurality of pixels, each of the plurality of pixels comprising a display element, the plurality of pixels being arranged in a display area; and an at least one actuator which is provided so as to fit a backside of the substrate and bends the substrate, wherein the at least one actuator is provided with a layer to shift from a flexible state to a state to have a predetermined shape and vice versa by being driven electrically, and the at least one actuator does not overlap the display element in a plan view.

  • Publication number: 20210033901
    Abstract: A column for defining the interval between a TFT substrate and an opposed substrate is formed at a crossing point between a drain line and a scanning line. At the crossing point where the column is formed, the drain line is formed to have a wider width to prevent light leakage. Further, at the crossing point where the column is formed, the scanning line is formed to have a narrower width to prevent increase of capacitance between the drain line and the scanning line. The column is formed at a crossing point corresponding to a specific color, e.g., a blue pixel B, so that a difference in transmittance and in characteristic of thin film transistors due to formation of the column is initially compensated.

  • Publication number: 20210024929
    Abstract: Developed and provided is: a nucleic acid agent that is efficiently delivered to the central nervous system, to which drug delivery is inhibited by the blood brain barrier mechanism, and that provides an antisense effect to a target transcription product at the delivery site; and a composition containing such a nucleic acid agent. Provided is a double-stranded nucleic acid complex consisting of a first nucleic acid strand and a second nucleic acid strand that are annealed to each other; wherein the first nucleic acid strand hybridizes with part of a target transcription product and has an antisense effect on the target transcription product; and wherein the second nucleic acid strand includes a base sequence complementary to the first nucleic acid strand and is conjugated to a phosphatidylethanolamine or an analog thereof.

  • Publication number: 20210010000
    Abstract: An object of the invention is to provide a low toxicity antisense nucleic acid medicine that can modulate expression of a target transcriptional product in the central nervous system and other sites of a subject. Provided is a low toxicity composition for modulating expression of a target transcriptional product in a site such as the central nervous system of a subject, having a nucleic acid complex formed by annealing together a first nucleic acid strand having an antisense oligonucleotide region with respect to the target transcriptional product, and a second nucleic acid strand having a complementary region that is complementary to at least part of the first nucleic acid strand.
