  • Publication number: 20230340405
    Abstract: Provided are a composition for inducing direct conversion from a somatic cell into a motor neuron, a motor neuron induced through direct conversion by introducing the composition into a somatic cell, a pharmaceutical composition for the prevention or treatment of nervous system disease and injury, a cell therapeutic agent, a composition for screening for a drug for the prevention or treatment of nervous system disease and injury, and a 3D printing biomaterial composition for constructing artificial tissue. When a composition of one aspect is used, differentiation from a somatic cell into a motor neuron can be efficiently induced through the expression of direct conversion inducers without going through the pluripotency stage of dedifferentiated stem cells. Thus, nervous system disease and injury can be effectively prevented and treated using the composition.

  • Publication number: 20210198011
    Abstract: Disclosed is a bulk bag having self-standing loops. The bulk bag is configured with a bag-shaped body having a reversed ā€œUā€-shaped loop protruding upwardly from an outside thereof and configured to flexibly stand upright by itself from a folded position upon unstacking of bodies, wherein the loop is coupled to the body at a position spaced downwardly apart from a top edge of the body by a predetermined distance, the loop having an air tube having a predetermined length and coupled to an outside of the loop. The loop is configured with a semicircular arc-shaped hook portion and ā€œIā€-shaped supporting portions respectively extending from opposite ends of the hook portion, and the air tube is coupled with the hook portion and an at least one supporting portion and is heat-treated and flexibly bent at a portion corresponding to a boundary point between the hook portion and the supporting portion.

  • Publication number: 20190226750
    Abstract: A refrigerator planar heating element is arranged inside a refrigerator to radiate heat. The refrigerator planar heating element includes a defrosting planar heating element including a first substrate having one surface on which a first pattern for radiating heat is printed with conductive ink, a second substrate having one surface on which a second pattern for radiating heat and having the same form as the pattern of the first substrate is printed with conductive ink, and an adhesive layer performing bonding such that the patterns of the first substrate and the second substrate are overlapped in a vertical direction. The invention has heating performance more excellent than that of conventional heating elements, and applies an inverse current patterning technique so as to make a current flow in opposite directions at both surfaces of a substrate, thereby effectively shielding electromagnetic waves.
