Abstract: Surface-modified silica microparticles that are functionalized with stabilized phospholipid vesicles are described herein. These stabilized vesicles can be functionalized with either transmembrane receptors or membrane associated receptors and used for affinity pull-down assays or other chromatographic separation modalities to provide affinity capture/concentration of low abundance ligands in complex mixtures with minimal sample preparation. Further described are methods and apparatus for forming polymer frits in a fused silica capillary. The capillary containing a monomer solution is placed between one or more heat sources connected to each other via a jig and operatively coupled to a temperature controller. The polymer frits are synthesized via thermal polymerization of the monomer solution using the heat sources, which allows for placement of the polymer frits at a spatially-defined location in the capillary.

Abstract: The present invention relates to the technical field of polymer science, and disclosed thereby is a bio-based polyarylene ether resin containing a furan ring structure and a preparation method thereof. A bio-based monomer containing a furan ring structure furan-2,5-bis(4-fluorophenyl)methanone (BFBF), which is inventively prepared by using a bio-based derivative furan dicarboxylic acid (FDAC), undergoes a nucleophilic substitution reaction with one or more from a dihydric phenol monomer and a dihalobenzophenone monomer to prepare a bio-based homopolymerized or copolymerized polyaryletherketone resin containing a furan ring structure. The introduction of a bio-base into the field of special engineering plastics diversifies the types of polyaryletherketone resins, while also effectively responding to an oil crisis.

Abstract: Microarray platforms and methods of fabricating said microarrays without traditional high aspect ratio barriers used to define individual array elements are described herein. Self-assembled nanoshells were stabilized with a polymerized scaffold to enhance the stability in physiological conditions and serve as an optical transducer upon molecular recognition events. Soft photolithography combined with surface chemistry was developed for covalent immobilization of nanoshells onto the pre-patterned arrayed microspots for rapid multiplexed detection of membrane-binding analytes. This robust fabrication methodology is amenable for general lipid structures, and thus facilitates the integration of stable membrane architectures into diagnostic and prognostic platforms. In particular, the microarray platform may be used in diverse applications ranging from the detection of pathogens, such bacterial toxin in biological matrices, to cellular membrane studies.

Abstract: The inventors examined the role of MK in experimental autoimmune encephalomyelitis, which is a human model for multiple sclerosis. As a result, they discovered that MK has the effect of inhibiting regulatory T cells, and that the autoimmune mechanism induced by type 1 helper T cells can be suppressed by inhibiting MK expression or its activity, thereby increasing the number of regulatory T cells. Furthermore, it was found that diseases associated with the functional disorder of regulatory T cells can be treated with the administration of an inhibitor that inhibits MK expression or activity.
