  • Patent number: 11959488
    Abstract: The present invention relates to a blower, the blower according to an embodiment of the present invention comprising: a lower case having a suction hole formed therein through which air is introduced; an upper case arranged on the upper side of the lower case and having a discharge hole formed therein through which air is discharged; and a fan arranged in the lower case and including a plurality of blades. Each of the plurality of blades includes a plurality of airfoils respectively extending along different camber lines from one another, and a leading edge of connecting the leading ends of the plurality of airfoils. Entrance angles formed by the respective camber lines of the plurality of airfoils and the rotation directions of the blades are different from one another. Thus, due to the curved shape of the leading edge and the design of a recessed notch, a flow separating from the leading edge is reduced, and thus, there is an advantage in that air volume performance is improved.

  • Publication number: 20240077084
    Abstract: A blower of the present disclosure includes: a lower case having a suction port; an upper case which has a pair of towers that are spaced apart from each other and form a space through which a discharge air flows therebetween; and a blower fan which is disposed inside the lower case and discharges air to the upper case, wherein each of the pair of towers has a discharge port that is elongated in an up-down direction and disposed closer to a rear end of the tower than a front end, and has an air guide, which is disposed therein, that guides the air discharged by the blower fan to the discharge port, wherein the air guide is convex upward, has one end disposed near a middle between the front end and the rear end of the tower, and has the other end disposed near a middle of a vertical height of the discharge port, wherein the other end is disposed higher than the one end, so that the direction of air flow discharged from the fan can be smoothly switched to the discharge port side by only a single air guide, ther

  • Publication number: 20080200419
    Abstract: An alternatively spliced form of transforming growth factor-beta2 (TGF-?2), herein denoted ?6-TGF-?2 is disclosed. ?6-TGF-?2 differs from TGF-?2 in the sequence of the three C-terminal exons. This novel protein is secreted, induced by cytotoxic stress in hematopoietic stem cells, and specifically blocks the enhancing effects of TGF-?2 on adult stem cells. ?6-TGF-?2 can be used to protect stem cells from cytotoxic stress, and to enhance maintenance of these cells in vitro during retroviral transduction. In addition, ?6-TGF-?2 can be used to slow aging and extend longevity.

  • Patent number: 7148013
    Abstract: Disclosed is a complex of the 11 kDa Ca2+ binding protein of 11 and Hepatitis B virus polymerase (HBVPol) which moves to Promyelocytic Leukemia Nuclear Body (PMLNB). Furthermore, the present invention discloses a method for controlling movement of the HBVPol/p11 complex into the nucleus of HepG2 cell with adjusting of intracellular Ca2+ ion concentration by administrating an agent for controlling calcium ion concentration in HepG2 cells.

  • Patent number: 6984521
    Abstract: There is provided a cell line that is prepared by transforming HEK293 cell with a human Kir2.1 gene using a retrovirus expression system, wherein the HEK293 expresses a stable ?1G T-type calcium channel. The cell line responds sensitively to KCl and forms an appropriate level of the membrane voltage so that the cell signaling pathway may be investigated by the molecular biological and biochemical studies.
