  • Publication number: 20240094186
    Abstract: Systems, devices, and methods for localizing magnets are useful for biological tissue analysis and other applications. Tissue analysis systems for use with a tissue analysis device may include a storage medium storing computer readable instructions that cause the execution of magnet localization methods. The system may include the tissue analysis device, which includes a magnet and a magnetometer array disposed adjacent to the magnet. When executed by a processor, the instructions cause operations, including recording a magnetic field of the magnet with the magnetometer array, simulating a simulated magnetic field at each magnetometer of the magnetometer array, and estimating positional information of the magnet based upon iterating simulated positional information of the simulated magnet.

  • Patent number: 11912745
    Abstract: Proteins, nucleic acids encoding the proteins, compositions comprising the proteins, and methods are provided. The proteins have the ability to be self-targeted to ICAM-1 and, if desired, enzymatically-released at acidic pH. The ICAM-1-targeting peptides are provided as single copies or multiples repeats, and can be separated by linkers from the enzyme segment, from which the ICAM-1 targeting peptides can be released, if desired, at acidic pH. These fusion proteins enhance the activity of the enzyme segment within or liberated from the fusion protein, and provide increased recognition and targeting of diseased organs, transport from the bloodstream across the endothelium into said diseased organ, and intracellular uptake and lysosomal trafficking by cells in them, both in peripheral tissues and the central nervous system. Representative nucleotide and amino acid sequences of these fusion proteins, as well as in vitro, cellular, and in vivo animal data are provided.

  • Publication number: 20220282002
    Abstract: This invention relates to the isolation and purification of nutritional supplements and prebiotics, such as xylo-oligosaccharides, and specifically the removal of color bodies, said xylo-oligosaccharides sourced from from ligno-cellulosic feedstocks such as sugar cane and sugar cane bagasse. Removal of color bodies provides greater purity in certain xylo-oligosaccharides as described. This process can also be applied to non-sugar cane feedstocks such as agricultural residues (wheat straw, corn stover, rice straw, etc.), purpose grown crops including but not limited to sugar cane, sorghum, Miscanthus, and woody biomass such as poplar.

    Abstract: Topographically-guided cell migration devices include a substrate, an ion-permeable surface layer having a unidirectional textured first side, and an electrode pair having interdigitated electrode digits disposed between the substrate and the ion-permeable surface layer. The unidirectional texture of the ion-permeable surface layer is configured to guide migration of a cell culture in a substantially linear migration direction. Other topographically-guided cell migration devices include a substrate, a surface layer having a unidirectional textured first side, and a cell confinement structure with two walls that run substantially parallel to the unidirectional texture in order to guide migration of the cell culture in a substantially linear migration direction.
