Abstract: The invention relates to a method for preparing an anti-counterfeiting modal fiber, including: mixing a pulp stock solution with a cellulose catalyst, alkalizing, aging, sulfonating, and then dissolving the pulp stock solution in an alkaline solution to obtain a treatment solution; mixing the treatment solution with multiple amino acid-metal chelates, filtering, defoaming and ripening to obtain a spinning stock solution; and mixing the spinning stock solution with a spinning bath additive, and wet spinning, followed by drafting, defoaming, desulfurizing, water washing, and other post-treatments, to obtain an anti-counterfeiting modal fiber, wherein the amino acid metal-chelates account for 0.5%-1.5% by weight of the spinning stock solution. Amino acid-metal chelates are used to anti-counterfeit and encrypt the modal fibers, and the anti-counterfeiting and encrypting is involved in the spinning stock solution of modal fibers.

Abstract: An anti-SIRP? antibody or an antigen-binding fragment thereof, and use thereof are provided. The anti-human SIRP? monoclonal antibody is obtained by means of immunizing mice, and a chimeric antibody and a humanized antibody are further obtained. The provided anti-SIRP? antibody or antigen-binding fragment thereof can bind to the human SIRP? protein, block the CD47-SIRP? signaling pathway, and have immune regulation effects such as enhancing phagocytosis. Further provided are a pharmaceutical composition and a nucleic acid molecule, and the use of the anti-SIRP? antibody or the antigen-binding fragment thereof in the preparation of a drug for inhibiting or treating diseases.

Abstract: The embodiment of the present disclosure provides a welding device, a welding method, and an installation and debugging method thereof. The welding device includes a baseboard, comprising: a left welding nozzle and a right welding nozzle, a power shaft, a bidirectional moving wheel, and two welding nozzle connecting shafts, wherein the welding nozzle connecting shafts are connected to the left welding nozzle and the right welding nozzle respectively, and the bidirectional moving wheel which is driven by the power shaft drives the two welding nozzle connecting shafts to move towards or away from each other.

Abstract: The present invention relates to a derivative of 13-oxidized ingenol, use thereof in the prevention and/or treatment of a disease associated with proliferation or tumor in a subject, or a cosmetic indication, and use thereof in the prevention and/or treatment of a disease responsive to neutrophil oxidative burst, a disease responsive to a release of IL-8 by keratinocyte, or a disease responsive to induction of necrosis.

Abstract: A bispecific antibody targeting human claudin and human PDL1 proteins, containing an anti-human claudin18.2 antibody moiety and an anti-PD-L1 antibody moiety. The bispecific antibody can not only bind to human claudin18.2 protein, but also block binding of PD-1/PD-L1, and can not only activate NK cells and kill tumor cells in the innate immunity, but also promote the killing effect of killer T lymphocytes on tumors in the acquired immunity. The bispecific antibody has better anti-tumor efficacy than an anti-claudin18.2 antibody alone.

Abstract: Provided are an anti-PD-L1 nanobody and an Fc fusion protein thereof, and an application thereof. The anti-PD-L1 nanobody and the Fc fusion protein thereof have strong specificity, high affinity, and weak immunogenicity to humans. In addition, same have high stability and a significant anti-tumor effect.

Abstract: Provided are an anti-CLDN18.2 antibody and a pharmaceutical composition thereof and a detection method therefor, wherein the heavy chain of the antibody is selected from any one of SEQ ID NOs: 1-7 or SEQ ID NOs: 15-30, and the light chain of the antibody is selected from any one of SEQ ID NOs: 8-14 or SEQ ID NOs: 31-46. The ability of the antibody to bind to cell lines and tumor tissue cells is more powerful than that of the existing antibody IMAB362, and the anti-tumor effect of the antibody is also more powerful than that of the existing antibody IMAB362.

Abstract: A method is presented for controlling process delay times between a) thin film deposition and lubricant application, and b) lubricant application and abrasive polishing. Applicants have discovered that for certain lubricants, a minimum delay time after the overcoat has been deposited before the lubricant is applied increases the number of disks passing the glide test after abrasive polishing. In addition, applicants have discovered that for certain lubricants, the abrasive polishing should take place within a maximum time window following the application of the lubricant. A computerized work-in-progress tracking system is preferably used to implement the method of the invention.
