  • Publication number: 20150043933
    Abstract: An image forming apparatus includes a sheet feed unit which feeds a sheet to an image forming unit forming an image on the sheet, a re-transport roller which reverses the sheet with a toner image fixed on the sheet and re-transports the sheet to the image forming unit, and a control unit which controls a sheet feed operation of the sheet feed unit for feeding the sheet. As the temperature of the re-transport roller sensed by the temperature sensing unit is decreased, the control unit retards the timing at which the sheet feed unit starts the sheet feed operation when a duplex image formation in which the image is formed on both sides of the sheet is performed after a one-side image formation is completed.

  • Publication number: 20150037078
    Abstract: The present invention provides a fixing device including a flexible cylindrical rotary member and an inner-surface opposing portion that opposes an inner surface of the rotary member at an end portion of the rotary member in a generatrix direction. The inner-surface opposing portion moves upstream in a recording material conveying direction in accordance with lateral shift of the rotary member in the generatrix direction. This restricts the lateral shift of the rotary member.

  • Patent number: 8426376
    Abstract: Because AK022567 has angiogenesis inhibitory activity, it is useful as an angiogenesis inhibitor. Furthermore, 4 splicing variants obtained from the same gene are also useful as an angiogenesis inhibitor. These 5 polypeptides, polynucleotides encoding the polypeptides and antibodies against the polypeptides are useful for screening of a candidate compound as an angiogenesis inhibitor or promoter. A compound obtained from the screening is useful as a medicine and can be used for a preventive or therapeutic agent for an angiogenesis related disease.

  • Patent number: 8187873
    Abstract: It is intended to provide a monoclonal antibody that specifically recognizes human soluble LOX-1, particularly a monoclonal antibody with a dissociation constant (Kd) for human soluble LOX-1 of 1×10?9 (M) or less. The antibody can be produced from a hybridoma prepared by a method including the following steps of: (1) immunizing a non-human animal with a prokaryotic cell-derived human LOX-1 extracellular domain; (2) collecting antibody-producing cells from the animal; (3) fusing the antibody-producing cells with myeloma cells; (4) selecting hybridomas that produce a monoclonal antibody reacting with the human LOX-1 extracellular domain from the fused cells obtained in the above step; and (5) selecting a hybridoma that produces a monoclonal antibody reacting with a eukaryotic cell-derived human LOX-1 extracellular domain from the selected hybridomas.

  • Publication number: 20090270314
    Abstract: The present inventors found out four kinds of fragments (42 kD, 36 kD, 32 kD, 27 kD) by forcibly expressing vasohibin in a vascular endothelial cell. The present inventors analyzed those fragments and, as a result, found out low molecular weight vasohibin which has an anti-angiogenic activity. The low molecular weight vasohibin is useful as a therapeutic agent for various diseases such as a vascular disease associated with angiogenesis, an inflammatory disease, an entoptic neovascular disease, a reproductive disease, a central nervous system disease and cancer and the like. In addition, the low molecular weight vasohibin is also useful as a marker for angiogenesis.
