  • Patent number: 8357779
    Abstract: The present invention relates to a proteinaceous construct (also designated as polymer-VWF-conjugate) comprising plasmatic and/or recombinant von Willebrand factor (VWF), said VWF being bound to at least one physiologically acceptable polymer molecule, as well as to a complex between said proteinaceous construct and at least one factor VIII (FVIII) protein. The physiologically acceptable polymer molecule can be, for instance, polyethylene glycol (PEG) or polysialic acid (PSA). Further the present invention relates to methods for prolonging the in vivo-half-life of VWF or FVIII in the blood of a mammal having a bleeding disorder associated with functional defects of or deficiencies of at least one of FVIII or VWF.

  • Patent number: 8338128
    Abstract: Suitable dyes are used herein to indicate the presence of microbial contamination by spraying them onto surfaces in the form of an aqueous solution. The dye solution may also be allowed to dry, thus producing the dried residue of an aqueous solution. It's believed that these dyes change color in response to a change in polarity of the environment. Since water is a polar solvent and most bacteria are made from non-polar substances, the presence of bacteria changes the polarity of the environment, triggering a change visible by the unaided eye.

  • Patent number: 8303972
    Abstract: Bioscaffoldings formed of hydrogels that are crosslinked in situ in an infarcted region of the heart (myocardium) by a Michael's addition reaction or by a disulfide bond formed by an oxidative process are described. Each of the bioscaffoldings described includes hyaluronan as one of the hydrogel components and the other component is selected from collagen, collagen-laminin, poly-l-lysine, and fibrin. The bioscaffolding may further include an alginate component. The bioscaffoldings may have biofunctional groups such as angiogenic factors and stem cell homing factors bound to the collagen, collagen-laminin, poly-l-lysine, or fibrinogen hydrogel component. In particular, the biofunctional groups may be PR11, PR39, VEGF, bFGF, a polyarginine/DNA plasmid complex, or a DNA/polyethyleneimine (PEI) complex. Additionally, the hydrogel components may be injected into the infarct region along with stem cells and microspheres containing stem cell homing factors.

  • Patent number: 8252565
    Abstract: The present invention relates to a method for production of a diol form represented by the formula (2), which includes filtering a culture fluid obtained by microbial conversion using a compound represented by the following formula (1a) and/or formula (1b) as a substrate, using a filter having an aperture size of 10 to 100 ?m; washing the residue on the filter with water or a solvent having an SP value outside the range of 8.3 to 20 (cal/cm3)1/2; subsequently dissolving the obtained cake in a solvent having an SP value of 8.3 to 20 (cal/cm3)1/2; and then filtering or centrifuging the solution. According to the present invention, 1-(2-hydroxyethyl)-2,5,5,8a-tetramethyldecahydronaphthalen-2-ol, which is useful as an intermediate for the production of 3a,6,6,9a-tetramethyldodecahydronaphtho[2,1-b]furan, can be efficiently produced at high purity.
