  • Publication number: 20210310080
    Abstract: This disclosure relates to a composition for diagnosing cancer by using potassium channel proteins; to a kit for diagnosing cancer comprising the composition; and to an information providing method for diagnosing cancer. Specifically, the composition or kit for diagnosing cancer provided in this disclosure may be used to diagnose the onset of cancer regardless of its type, by measuring the expression levels of potassium channels, KCa3.1 channel and KCa2.3 channel, or a regulator thereof from vascular endothelial cells treated with a sample of a subject, or from red blood cells isolated from the subject, and thus can be widely utilized in determining the stages of progression (growth, metastasis, prognosis, and recurrence) of various cancers.

  • Patent number: 10434400
    Abstract: The present invention relates to a transformer toy car that automatically transforms the shape to turn a card over to provide the information on the card, if the card is attached to the transformer toy car. The transformer toy car includes: a separable toy car body; and cards adapted to be attached to the underside of the toy car body, wherein if one of the cards is attached to the underside of the toy car body, a portion of the separable toy car body is separated, and a portion of the separated toy car body pressurizes a floor surface, thereby making the toy car body stand up or turn over and thus allowing the underside surface of the card attached to the underside of the toy car body to be exposed to the outside.

  • Publication number: 20160001191
    Abstract: A top which can facilitate the coupling of a winder is provided. The toy top comprises: a blade; a shaft of which one end is fixed to a lower portion of the blade; a pinion to be inserted and coupled to the middle of the shaft; and a shaft holder capable of accommodating the pinion-coupled shaft in a rotating manner, wherein the shaft holder comprises winder connectors (for rotating the pinion. Particularly, the winder connectors comprise: a cut portion for contacting a part of a first portion of a winder on a lateral side; and a guide groove for allowing a second portion extended from the first portion of the winder to be stopped at stepped protrusions inside the cut portion so as to prevent the second portion from being separated from the lateral side when a part of the first portion of the winder is contacted to a lateral side and then the winder is moved to the lateral side.
