  • Patent number: 11882942
    Abstract: An assembly for a seat includes a pivot hub defining multiple rotation axes, and a displacing module attached to the pivot hub. Extendable legs are rotatably coupled to the pivot hub and comprise locking devices movable between an unlocked position, in which the legs, when extended, are enabled to retract, and a locked position, in which the legs, when extended, are prevented from retracting. The legs are rotatable between an intermediate position and a deployed position. When the legs are extended, and when in the intermediate position, the displacing module engages the locking devices to move the locking devices from the locked position to the unlocked position. When the legs are extended, rotating the legs from the intermediate position to the deployed position brings the displacing module out of contact with the locking devices.

  • Publication number: 20240016891
    Abstract: The present invention relates to a use of a cell adhesion molecule-related/down-regulated by oncogene (Cdo) protein or a gene encoding the same for preventing or treating neuromuscular diseases caused by damage to motor neurons, particularly muscle stem cells and neuromuscular junctions, due to aging, oxidative stress, and the like; and a method for screening for candidates for activating the expression of Cdo. When Cdo is deleted in motor neurons or neuromuscular junctions, aggravation of damage to degenerative motor neurons due to aging, and DNA damage caused by oxidative stress and inflammation are caused, which may cause neuromuscular diseases. Thus, the diseases can be treated through overexpression and activity of the Cdo protein and the gene encoding the same.

  • Publication number: 20230405185
    Abstract: The present invention relates to a composition for preparing a decellularized scaffold, including nano graphene oxide. The present inventors crosslinked nano graphene oxide to a decellularized liver scaffold to strengthen the properties of the scaffold and suppress protease activity of the scaffold, and thus have established an optimum crosslinking condition exhibiting the effects of anti-inflammation and polarization to M2 macrophages. That is, since it is confirmed that nano graphene oxide strengthens the durability of the scaffold so that biodegradation is suppressed and, simultaneously, inflammatory responses that may occur after transplantation are minimized, it is expected that nano graphene oxide can be effectively used in the production and transplantation of clinically applicable artificial organs.

  • Publication number: 20230392127
    Abstract: Provided is a method for constructing an atopic dermatitis skin organoid from human pluripotent stem cells. It was observed that ALI-skin organoids of the presently claimed subject matter formed skin cells, appendages, neural cells, adipocytes, and the like in similar structures to those in the real skin and exhibited greatly improved follicle growth, compared to skin organoids constructed by existing culture methods. In addition, as a result of treatment with Staphylococcus aureus to construct an atopic dermatitis model, a good simulation was made of the characteristics of atopic dermatitis, such as damaged skin barriers, increased epithelium-derived cytokines and downregulated epidermal stem cell expression, causing Staphylococcus aureus colonies, and the like. Thus, the skin organoid of the presently claimed subject matter is expected to find advantageous applications as a real skin model and an atopic dermatitis model.

  • Publication number: 20230372454
    Abstract: The present invention relates to a use for, by using the protein arginine methyltransferase 1 (PRMT1) protein or a gene encoding the same, preventing or treating a neuromuscular disease induced by motor neurons, particularly, damage to motor neurons caused by oxidative stress in the neuromuscular junction; and a method for screening a candidate material for activating the expression of PRMT1. PRMT1 deficiency in the motor nerve or neuromuscular junction induces aggravated degenerative motor nerve damage caused by aging, and DNA damage caused by oxidative stress and inflammation, thereby enabling the induction of neuromuscular disease, and thus the disease may be treated through the overexpression and activity of the PRMT1 protein and a gene encoding the same.

  • Publication number: 20230321153
    Abstract: The present invention relates to a method of manufacturing an animal cartilage-derived injectable composition, an injectable composition manufactured by the method, and a use thereof. The injectable composition of the present invention includes a collagen-containing biomaterial in a formulation injectable into joint cavity and may induce cartilage tissue regeneration by repairing tissue via direct injection to a target region without surgical incision. In addition, the injectable composition may be used as a therapeutic agent for arthritis by alleviating osteoarthritis not only because the animal cartilage-derived extracellular matrix contained in the injectable composition protects articular cartilage tissue but also because an environment capable of regenerating damaged articular tissue is created by inducing differentiation of intra-articular stem cells into chondrocytes.
