Abstract: Compositions comprising a population of oligodendrocyte progenitor cells (OPCs), as well as methods of making and using the same, are provided. In one aspect, a container comprising a composition, where the composition comprises a population of cells comprising a plurality of OPCs, and where the population of cells comprises less than 15% undesirable cell types is provided. In another aspect, the population of cells comprises less than 15% undesirable epithelial lineage cells. In yet another aspect, the population of cells comprises less than 2% K7 positive cells. In an aspect, a population of cells comprising a plurality of oligodendrocyte progenitor cells is capable of forming less than one epithelial cyst per 100,000 cells in a cyst assay is provided. An even further aspect of the present disclosure is a container comprising a composition, where the composition comprising a plurality of oligodendrocyte progenitor cells is useful in treating treat stroke, spinal cord injury, and multiple sclerosis.

Abstract: Exemplified methods and systems facilitate presentation of data derived from measurements of endotoxins in fluid samples. In particular, the exemplified methods and systems facilitate presentation of such measurements in a graphical user interface and/or in a report for endotoxin concentrations in a fluid sample. The presentation facilitates a unified and intuitive graphic visualization that are presented within a single interactive interface and/or report.

Abstract: A chip has formed thereon integrated circuit elements, which include a main circuit and an associated non volatile memory structure. A test result associated with prior testing of a function of the main circuit is stored in the non volatile memory structure. Additional apparatus and methods are disclosed.

Abstract: An arrangement of endcaps particularly formed and arranged for use in connection with composite deck beams particularly adapted to use on rail car running boards but is also suitable to other beam type decks such as those used on semi-trailers, in marine applications or as industrial catwalks. The endcaps close the ends of fiberglass reinforced plastic running boards, complementing the strength, economy and durability of such materials.

Abstract: A railcar coupler carrier wear plate is formed in an “L” shaped section for ease of insertion and replacement in a coupler carrier and for efficient manufacture, the coupler carrier wear plate being retained in the coupler carrier with a bracket arrangement that can be readily affixed to the coupler carrier as by welding and which can also be adapted to protect the coupler carrier wear plate in the event of a coupler override.

Abstract: A self-lubricating plastic coupler carrier wear plate is formed in a generally T-shape having an outer flange and an inner flange conforming to said T-shape, said web being notched proximate said inner flange for adequate clearance with railcar draft gear.

Abstract: A method for enriching rare cell populations from a whole blood sample by separating rare cell fractions from whole blood sample according to the relative charge density and/or the relative binding affinity for a leukocyte depletion solid phase matrix is described. The enrichment method may be operated stand alone, or as a pre or post-processing step in conjunction with a charge-flow separation method.

Abstract: A railroad car having an improved draft gear assembly including a center sill structure terminating at one end in a draft center sill section having a yoke mounted therewith. The yoke includes first and second yoke members extending longitudinally. An interlocking coupler member including a head portion and a shank portion is mounted with the yoke. A connector assembly holds the interlocking coupler member in position in the yoke. The interlocking coupler member includes a rear butt portion positioned internally of the connector assembly for engaging a follower block mounted substantially between the first and second yoke members. A resilient member is mounted between the follower block assembly and the end of the yoke.
