    摘要: A target particle transferring device is disclosed, which comprises: (a) a substrate with a thickness of T and a width of W, having top and bottom portions, the top portion having a top surface and the bottom portion having a bottom surface; (b) a notch structure formed in the bottom portion of the substrate, comprising: a groove with a width of W1, located at a distance oft below the top surface of the substrate, wherein the groove is formed in the bottom portion from the bottom surface extending toward the top portion; and (c) a target substrate portion with a width of W2 and a thickness of T, located in the top and bottom portions of the substrate and being surrounded by the groove. Methods of transferring a target particle from one device to another is also disclosed.

    摘要: Provided herein are compounds of Formula (I). The compounds described herein are useful in treating a disease associated with the expression of endogenous embryonic/fetal globin (e.g., γ globin) in erythrocytes (e.g., treating β-thalassemia and/or sickle cell disease through at least the induction of the globin gene expression in erythrocytes), and/or anemia (β-thalassemia and/or sickle cell anemia). The compounds described herein are useful in treating, delaying, and/or preventing the adverse effects of β-thalassemia and/or sickle cell disease, inducing γ globin production, and/or inducing the expression of embryonic/fetal globin genes in a subject, cell, tissue, or biological sample. Also provided in the present disclosure are pharmaceutical compositions, kits, and methods of using the compounds for inducing γ globin production described herein and for treating any of the target diseases described herein.

    摘要: This invention provides a high-efficient single-cell collection method using a specially designed collection well and collection pipet tip for particle/cell collection from the collection well. The structures of the collection well and pipet tip eliminate fluidic dead volume in the collection, resulting in all (or most) of the particles/cells can be brought into the collection pipette tip with the flow. The advantages of this invention in cell manipulation include high cell collection efficiency, low cell damage and easy operation procedure.

    摘要: The invention provides a nanoemulsion adjuvant and a preparation method thereof, which are composed of the following components: a continuous aqueous phase containing H2O molecules, an oil phase material containing fats and oils, and an emulsion system for stabilizing the interface between the continuous aqueous phase and the oil phase, and the emulsion system is an emulsifier mixture. The adjuvant is characterized in that the emulsion system does not contain an ionic emulsifier and the particle size of the emulsion is between 20 and 200 nanometers. The use of the nanoemulsion adjuvant can prevent toxicity and possible harm of ionic emulsifiers to human cells, and provide a vaccine preparation capable of eliciting a high degree of immune response.

    摘要: A sub-nanometer gold sticker for blocking efficiently endotoxin activity to protect against sepsis is disclosed. The sub-nanometer gold sticker comprises a gold nanocluster that serves as a flake-like substrate and a coating of short alkyl motifs that act as an adhesive, allowing the sub-nanometer gold sticker to dock with LPS by compacting the intramolecular hydrocarbon chain-chain distance (d-spacing) of lipid A, an endotoxicity active site that can cause overwhelming cytokine induction resulting in sepsis progression. Methods of blocking endotoxin activity, and suppressing pro-inflammatory cytokines are also disclosed. Also disclosed is a method of protecting against endotoxin-induced sepsis via increasing critical micelle concentration for the inhibition of LPS non-lamellar aggregation.
