  • Publication number: 20100210547
    Abstract: The present invention relates to a fusion protein comprising IGF-I or an IGF-I variant N-terminally linked to the C-terminus of a propeptide. The invention relates also to a method involving the use of the aforementioned fusion protein in the production of a lysine-PEGylated IGF-I or IGF-I variant. The method comprises the steps of cultivating a prokaryotic host cell comprising an expression vector containing a nucleic acid encoding the fusion protein and causing the cell to express the fusion protein, recovering and PEGylating said fusion protein, cleaving said PEGylated fusion protein with IgA protease, and recovering lysine-PEGylated IGF-I or IGF-I variant. The invention relates also to a lysine-PEGylated IGF-I or IGF-I variant produced using the above method. In addition, the invention relates to a method for treating a neurodegenerative disorders like Alzheimer's Disease using the lysine-PEGylated IGF-I or IGF-I variant and a composition comprising the lysine-PEGylated IGF-I or IGF-I variant.

  • Publication number: 20100121036
    Abstract: Method for the production of IGF-I, characterized by cultivating a prokaryotic host cell comprising an expression vector containing a nucleic acid encoding a fusion protein comprising said IGF-I N-terminally linked to the C-terminus of a propeptide, whereby said propeptide ends C-terminally with amino acids -Y-Pro, wherein Y is selected from the group consisting of Pro, Pro-Ala, Pro-Gly, Pro-Thr, Ala-Pro, Gly-Pro, Thr-Pro, Arg-Pro, or Pro-Arg-Pro, recovering and cleaving said fusion protein with IgA protease, and recovering said IGF-I. IGF-I is useful for the treatment of neurodegenerative disorders like Alzheimer's Disease.

  • Publication number: 20100107425
    Abstract: A method for making a razor blade having a bent portion is disclosed. The method includes: providing an elongated strip of stainless steel that can be 0.076 mm thick; hardening the strip; providing a cutting edge along an edge of the strip and providing coating(s) on the cutting edge. The stainless steel has a carbon content preferably between 0.45% and 0.55% by weight. The strip is separated lengthwise into discrete razor blades. The bent portion of the razor blade is then formed using a swivel bending process. When the razor blade is bent to define an included angle of 90 degrees between planar regions adjacent the bent portion and an inner surface having a radius about 0.3-0.35 mm, the outer surface of the bent portion is free from macro-cracks.

  • Publication number: 20100024504
    Abstract: The invention relates to a device (1) for cooling a metal strip (2) between two rolling stands (3), wherein the strip (2) is led over a leading-over element (4) of a flat form and arranged under the leading-over element (4) is a spraying element (5), which directs cooling medium (7) onto the underside (8) of the strip (2) through at least one opening (6) in the leading-over clement (4). To achieve an improved spray pattern, the invention provides that at least two openings (6) are introduced into the leading-over element (4), said openings being arranged next to each other in a direction transverse (Q) to the conveying direction (F) of the strip (2) and having an elongated form, wherein the longitudinal axis (9) of the opening (6) is aligned at an angle (?) with respect to the conveying direction (F) of the strip.

  • Publication number: 20080229583
    Abstract: A razor cartridge is provided with a skin engaging structure at the cap and/or guard surface of the razor cartridge. The skin engaging structure has an array of closely spaced elongated protrusions integrally formed with a substrate. In use, the protrusions produce a pleasant tactile sensation tending to reduce shaving discomfort. The protrusions are formed by closely packed molded flexible filaments that can be less than 0.25 mm wide and have spacing between adjacent protrusions less than 0.2 mm. The protrusions can have a density greater than 5 protrusions per mm2. The skin engaging structure can be molded from e.g. an olefin polymer. The substrate can be integrally formed with a housing of the razor cartridge.
