  • Patent number: 8334274
    Abstract: Follistatin-like protein (FSTL-1) is a secreted glycoprotein of unknown function, first isolated from mouse osteoblastic cells as a transforming growth factor-?1-inducible gene. The inventors have discovered that FSTL-1 is a proinflammatory mediator. As such, the invention provides for composition and methods of using agents that bind to FSTL-1 to modulate various types of inflammation (e.g., autoimmune diseases). Inhibitors and antagonists of FSTL-1, particularly antibodies or antibody fragments, may be used to treat conditions related to inflammation, such as arthritis. In addition, the inventors have discovered that FSTL-1 has a role in the Th17 pathway. Accordingly, the invention provides for compositions and methods of using agents which bind to FSTL-1 to modulate the generation of Th17 cells. Such agents are useful for delaying development of and treating diseases associated with undesired production of Th17 cells, such as autoimmune diseases.

  • Patent number: 8333523
    Abstract: A recording device includes a feed tray for storing sheets, a first conveying path, an arm having one end attached to a pivot, and a roller attached to the other end of the arm. The roller feeds the sheet to the first conveying path. A recording unit is positioned in the first conveying path, and records an image onto the sheet. The recording device also includes a second conveying path between the pivot and the feed tray, and a path changing unit. The path changing unit moves between a first position, where it discharges the sheet, and a second position, where it conveys the sheet to the second conveying path. The arm moves between a third position where the roller contacts the sheets in the feed tray, and a fourth position where the roller is above the second conveying path.

  • Patent number: 8327994
    Abstract: A method and apparatus for removing notes having gross defects from a currency processing machine prior to the notes entering the primary detection function of the machine. The invention involves the use of a gross defect detector module which detects notes having gross defects that could jam the machine if such defects were note detected and the notes were allowed to continue down the note path for processing. The invention works in conjunction with a conventional reject pocket located further downstream in the note path for the collection of notes identified as rejects during the subsequent main detection function.
