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.

Abstract: Disclosed in the present invention is an optimized cell transplant. The optimized cell transplant is formed by performing gene induction and modification on a mesenchymal stem cell in the form of a small molecule and protein composition. The expression levels of CD200 gene, Galectin-9 gene and VISTA gene can be increased synchronously after cell culture. Vector virus infection and plasmid transfection are not required in the cell preparation process, so that high biological safety and great clinical application value of cells are achieved.

Abstract: The present disclosure relates to an integrated chip. The integrated chip includes an image sensing element disposed within a substrate. A gate structure is disposed along a front-side of the substrate. A back-side of the substrate includes one or more first angled surfaces defining a central diffuser disposed over the image sensing element. The back-side of the substrate further includes second angled surfaces defining a plurality of peripheral diffusers laterally surrounding the central diffuser. The plurality of peripheral diffusers are a smaller size than the central diffuser.

Abstract: A protection circuit includes a pre-charge rectifying circuit, a pre-charge resistor, a varistor, a switch, a main rectifying circuit, a bulk capacitor, and a control circuit. The pre-charge rectifying circuit is connected with an AC power source. The pre-charge resistor and the varistor are connected between the pre-charge rectifying circuit and the switch. The switch is further connected with a first node. The main rectifying circuit is connected between the AC power source and the first node. The bulk capacitor and the control circuit are connected between the first node and a ground terminal. The control circuit generates a first control signal to control the switch. The control circuit further generates a control signal set to control the main rectifying circuit.

Abstract: A surge current suppressing circuit is applied between an AC power and an electronic device that receives the AC power via a first AC power line and a second AC power line. The surge current suppressing circuit has a first input fuse connected to the first AC power line, and a first air-core inductor connected in series with the first input fuse on the first AC power line to suppress a surge current. Depending upon the practical applications, the surge current suppressing circuit can further have a second air-core inductor connected to the second AC power line, a capacitor connected between the two AC power lines or both.
