Abstract: A static water sterilization module is provided according to the present application, which includes a lamp holder, a light-transmitting plate, a lamp plate, a sterilization lamp, a first sealing ring, a clamping member and a waterproof potting adhesive. The light-transmitting plate is mounted on the lamp holder. The lamp plate is mounted in the lamp holder. The sterilization lamp is mounted on the lamp plate. An inner surface of the lamp plate, an inner surface of the light-transmitting plate and an inner wall of the lamp holder form a sealing chamber for mounting the sterilization lamp. The first sealing ring abuts against an outer surface of the lamp plate. The clamping member is configured to press the first sealing ring and the lamp plate. The waterproof potting adhesive is configured to encapsulate a base chamber between the outer surface of the lamp plate and the lamp holder.

Abstract: An LED human centric lighting device includes a substrate, an LED light emitting chipset and at least two blue light chipsets with different color temperatures arranged on the substrate, a fluorescent colloid and an enclosure. The LED light emitting chipset includes multiple LED light emitting chips, and each of the blue light chipsets includes multiple blue light emitting chips with same color temperature. Each of the blue light chipsets forms a color temperature light emitting area, and the different color temperature light emitting areas are separated by the enclosure. The substrate is provided with a control circuit for controlling light emission of the corresponding color temperature light emitting area, and the fluorescent colloid is arranged in the enclosure. The LED light emitting chip and at least two blue light emitting chips with different color temperatures are assembled in the device, which can reduce a volume of the device.

Abstract: An ultraviolet LED device, including: a substrate, where a pad is located at an upper surface of the substrate, and another pad is located at a lower surface of the substrate; an ultraviolet LED chip; a chip fixing portion, configured to attach the ultraviolet LED chip to the pad; a high-reflective layer, located at an upper surface of the pad and surrounding the chip fixing portion; a cover lens attached to the substrate, where the cover lens and the substrate form a cavity for accommodating the ultraviolet LED chip. A utilization rate of the ultraviolet light is improved, a manufacture process is simplified, and a cost is reduced for ultraviolet LED devices.

Abstract: Disclosed are a stem cell generator, a construction method therefor and the use thereof. The stem cell generator is formed by implanting a biomaterial loaded with active substances and/or cells, or a biomaterial with an osteogenic induction capability into animal or human bodies and producing organoids upon development.

Abstract: The present invention provides, inter alia, a multiply auxotrophic cell line that is deficient in genes encoding enzymes that catalyze steps in the de novo synthesis of the pyrimidine and purine pathways, such as, e.g., uridine monophosphate synthetase (UMPS) and 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/IMP cyclohydrolase (ATIC), respectively, for the production of recombinant proteins such as recombinant monoclonal and bispecific antibodies. Methods for preparing the multiply auxotrophic, in particular the doubly auxotrophic and octa-auxotrophic cell lines disclosed herein, methods for selecting a cell expressing a protein of interest, methods for producing a protein of interest, methods for optimizing the activity of a protein of interest, and kits for selecting a cell expressing a protein of interest, are also provided. In addition, recombinant proteins such as antibodies, including monoclonal and bispecific antibodies, made by the methods of the present disclosure are also provided.

Abstract: Disclosed is a stem cell generator for the generation of organoids after the development of biological materials loaded with active substances which are implanted into an animal or a human body. The active substances are mesenchymal stem cells, bone morphogenetic protein-2 or bone morphogenesis protein-7, other growth factors/polypeptides or growth factors/polypeptide combinations having the ability of inducing bone regeneration, or combinations thereof. The stem cell generator contains various types of blood cells and hematopoietic progenitor/stem cells having complete functions. The produced stem cells are used for treating hematopoietic damage, and can treat bone marrow failure and leukemia caused by radiotherapy/chemotherapy.
