Abstract:
The invention concerns oligosaccharides and polysaccharides as well as the use of these oligosaccharides and/or polysaccharides, which contain the sugar unit N-acylglucosamine or N-acylgalactosamine for the production of hemocompatible surfaces as well as methods for the hemocompatible coating of surfaces with said oligosaccharides and/or polysaccharides, which imitate the common biosynthetic precursor substance of heparin, heparan sulphates and chitosan. The invention further describes methods for producing said oligosaccharides and/or polysaccharides and discloses various possibilities of using hemocompatibly coated surfaces. The invention relates particularly to the use of said oligosaccharides and/or polysaccharides on stents with at least one according to invention deposited hemocompatible coating, which contains an antiproliferative, antiinflammatory and/or antithrombotic active agent, methods for the preparation of said stents as well as the use of said stents for the prevention of restenosis.
Abstract:
A method and apparatus create a way of controlling alternative values of cell contents of a data flow network. Alternative values are computed from alternative formulas, which may be turned on and off in separate layers. Typically, one formula is provided for each layer for each cell of the data flow network. Layers can be grouped together to model different scenarios and can be added or removed.
Abstract:
A system may include invocation of a first analytical view to present first data filtered based on at least one variable value, reception of a selection of a cell of the first analytical view, creation, in response to the selection, of a first context object instance identifying the cell, the first analytical view and the at least one variable value, reception of a selection of a second analytical view, creation, in response to the selection of the second analytical view, of a second context object instance based on the first context object instance, the second context object instance identifying the second analytical view and the at least one variable value, and invocation of the second analytical view based on the second context object instance.
Abstract:
The invention relates to stents and catheter balloons having optimized coatings for eluting rapamycin as well as methods for manufacturing these coatings.
Abstract:
The invention relates to a data transmission device for transmitting data between a first bus system and a second bus system with a copy table (103) for providing an output sequence of data of the first bus system and a transmission device (101) for transmitting data between the first bus system and the second bus system according to the output sequence.
Abstract:
The invention relates to a bus coupler which converts a network-specific telegram arriving from an external network to an internal data telegram which transmits only the payload data from the network-specific telegram. The internal data telegram also contains at least one state information field for internal control information. The internal data telegram is transferred from the bus coupler to an internal bus system to which multiple bus users are connected in series. Each bus user connected to the internal bus system is able to monitor, in a decentralized and preferably autonomous manner, the communication quality of the lower-level bus system, and to initiate actions, depending on the implementation, on the basis of the internal control information received from the bus coupler, the internal control information generated by the particular bus user, and/or the internal control information received from the directly adjacent bus users.
Abstract:
An adsorbent for whole blood in the form of essentially spherical non-aggregated particles. The adsorbent comprises a porous carrier material having an average pore size of ≦1.5 μm, whereby a maximum of 50% of the pore volume may be in pores having a pore size of >1.5 μm, whereby the outer surfaces of the porous carrier material have at least one surface modification M1 so that the outer surface essentially does not interact with blood cells, and the inner surfaces of the porous carrier material, e.g., the surfaces of the pores of the porous carrier material, have at least one surface modification M2 which interacts with substances present in blood.
Abstract:
The invention pertains to a modular data transmission system (5) with several modules or bus nodes (10, 20, 30) that can be arranged adjacent to one another in a row. The data transmission system (5) comprises a first bus node (10) that features a first transmitter (70; 150, 151) for the wireless transmission of data and an electrical connector (190, 195), as well as a second bus node (30) that features a first receiver (100; 180, 181) for the wireless reception of data and an electrical connector. Both bus nodes (10, 30) are detachably fixed on a mounting rail (2) such that they are arranged adjacent to one another in a row. In addition, the first and second bus nodes (10, 30) are respectively detachably connected to a bus receptacle (130, 132), wherein each bus receptacle (130, 132) features an electrical mating connector (190, 195) that is coupled to the electrical connector (260, 265) of the respective bus node (10, 30) in the connected state in order to transmit energy, as well as a positioning device (140, 142) for positioning the respective bus node (10, 30).
Abstract:
In an exhaust gas recirculation line holder of an internal combustion engine wherein a line section of an exhaust gas recirculation line is integrated into the holder which is supported on the engine block and/or the vehicle frame, the holder is provided with a shaped part, in particular a cast part, with the line section of the exhaust gas recirculation line formed therein and a support structure also being formed integrally with the holder so that manufacturing costs, assembly time and assembly expenditure are reduced.
Abstract:
The present invention relates to in vitro cultured skin tissue, and in particular to cultured skin tissue comprising exogenous genes encoding angiogenic growth factors. In some embodiments, the keratinocytes express exogenous angiopoietin-1 or a member of the VEGF family, preferably VEGF-A. In particularly preferred embodiments, the keratinocytes are incorporated into cultured skin tissue.
