  • Patent number: 11253599
    Abstract: The invention relates to the field of analgesics. According to the invention, a kit or composition, particularly a pharmaceutical composition or a pharmaceutical kit, is provided, comprising a nanocarrier which is a hyperbranched polymer, such as a dendritic polymer or dendrimer, preferably having a molecular weight of 1,000-100,000 g/mol, and an analgesic which, when administered without nanocarrier, has both peripheral and central analgesic effect, preferably an opioid such as nalbuphine. According to the invention, the analgesic in this composition mainly or exclusively has a peripheral effect and thus reduces side effects triggered by the activation of central or intestinal opioid receptors. It is used for the treatment of peripheral pain and/or inflammation. The invention also relates to particularly suitable nanocarriers.

  • Publication number: 20210220145
    Abstract: An expandable spinal fusion implant including first and second endplates coupled to an expansion member that sits within a housing. The expansion member is translated by a drive mechanism, whereby translation of the expansion member by the drive mechanism in a distal and proximal directions causes the distance between the endplates to increase and decrease, respectively.

  • Patent number: 10668147
    Abstract: Complexes suitable for targeting and killing a human target cell comprising a first polypeptide with a binding structure for binding the complex to the cellular surface receptor CD89 (e.g. with an anti CD89 antibody) presented on the cell surface of the human target cell and a second polypeptide comprising a toxic effector domain, preferably Pseudomonas exotoxin A); to nucleic acid molecules encoding said complexes, vectors, host cells containing the nucleic acids and methods for preparation and producing such complexes; compositions and methods for using said complexes for the treatment of diseases, in particular of cancer diseases like leukemia.

  • Publication number: 20200001804
    Abstract: The invention relates to a sound protection panel for cladding a wall of an automotive vehicle, the panel includes a mass-spring system. The panel has a lower spring layer based on a resiliently compressible material, an upper mass layer based on resiliently compressible foam flakes, the flakes being bound together by a two-component fibre-based bonding agent comprising a core. The core is fusible at a high temperature or infusible, and a sheath fusible at a lower temperature, the flakes being fused with the sheath to form an upper agglomerated layer.
