  • Publication number: 20240117314
    Abstract: The present invention relates to a method for preparing a modified stem cell, including the following steps: a cell culture step: culturing stem cells in a first culture medium of a culture dish at a predetermined cell density, and removing the first culture medium after a first culture time to obtain a first cell intermediate; an activity stimulation step: preserving the first cell intermediate in a freezing container having a cell cryopreservation solution, and performing a constant temperature stimulation treatment or a variable temperature stimulation treatment for at least more than 1 day; and a product collection step: after completing the activity stimulation step, placing the freezing container in an environment at a thawing temperature for thawing, and then removing the cell cryopreservation solution to obtain the modified stem cell. The modified stem cell can release at least one or more of IL-4, IL-5, IL-13, G-CSF, Fractalkine, and EGF.

  • Publication number: 20220104678
    Abstract: A tile scraper structure contains: a handle and a blade module. The handle includes a grip portion, a connection segment, an accommodation cavity, a slidable switch having a pull lever, and a positioning element which has a fixing loop and a protrusion. The connection segment has a polygonal orifice and a slot. The blade module includes a blade and a locating seat accommodated in the polygonal orifice. The locating seat has a notch configured to engage with the protrusion. The handle further includes a spring received in the accommodation cavity and abutting against the slidable switch, such that the slidable switch actuates the positioning element so that the spring urges the protrusion to engage with the notch.

  • Patent number: 7831060
    Abstract: A method for protecting content of vector graphics formats is provided. A first vector graphics is scrambled to generate a second vector graphics. Then a plurality of pixel samplings are performed by the first vector graphics which generating at least a recovery information object according to a predetermined graphics. The predetermined graphics is watermarked to generate a watermark object. And the recovery information object is encoded and embedded in the watermark object to generate a recovery information watermark. Finally, the second vector graphics, the recovery information watermark, and the recovery code are combined to generate a protected first vector graphics.
