Patent AT-E298003-T1 (AT)
Inventor: STECK PETER
IPC: G01N33/53
Filed: 1998-08-26
Granted: 2005-07-15
Abstract: A specific region of chromosome 10 (10q23.3) has been implicated by series of studies to contain a tumor suppressor gene involved in gliomas, as well as a number of other human cancers. One gene within this region was identified, and the corresponding coding region of the gene represents a novel 47 kD protein. A domain of this product has an exact match to the conserved catalytic domain of protein tyrosine phosphatases, indicating a possible functional role in phosphorylation events. Sequence analyses demonstrated that a number of exons of the gene were deleted in tumor cell lines used to define the 10q23.3 region, leading to the classification of this gene as a tumor suppressor. Further analyses have demonstrated the presence of a number of mutations in the gene in both glioma and prostate carcinoma cells. Methods for diagnosing and treating cancers related to this tumor suppressor, designated as TS10q23.3, also are disclosed.

Abstract: An embolic protection device has a collapsible filter element (105) mounted on a carrier such as a guidewire (101). The filter element (105) collapses into the outer end of a catheter (118) for deployment and retrieval through a vascular system of a patient. The filter element (105) has a collapsible filter body with a proximal inlet end and a distal outlet end. The proximal inlet end has inlet openings sized to allow blood and embolic material enter the filter body. The outlet end has outlet openings which allow through passage of blood but retain embolic material within the filter body. After use, the catheter (118) is movable along the guidewire (101) to engage the proximal end of the filter element and close the inlet openings before sliding over the filter element from the proximal end to the distal end to progressively collapse the filter body on the guidewire (101) for retrieval. The filter element (105) may conveniently be mounted on a tubular sleeve (104) which is slidable and rotatable on the guidewire (101) between spaced-apart stops (106, 120) on the guidewire (101) which allows some manipulation of the guidewire independently of the filter when the filter is in use.

Abstract: Device for write precompensation of data signals to be recorded on a magnetic medium, which device has an input for receiving input data signals and an output for supplying the output signals to be recorded, at least a plurality of the signal transitions in these output data signals being delayed with respect to the corresponding signal transitions in the input data signal, the signal path between the input and the output including a series arrangement of a filter circuit and a hysteresis circuit, which hysteresis circuit receives the output signal of the filter circuit and supplies a binary signal as its output signal. This write precompensation device simply enables allowance to be made for the influence of a large number of preceding symbol values on a transition to be recorded. When the device is combined with a known write compensation device it suffices to use a simple filter.

Abstract: Method for providing manufacturing-related data in the large-scale production of manufactured objects, in particular, automobiles, includes a data collecting device assigned to each manufactured object, with manufacturing-related data being input into the data collecting device at least in a part of the manufacturing sections of the large-scale production, and with the data being transmitted at least partially by the corresponding data collecting device to one central device during manufacturing. Manufacturing-related data consequently are made centrally available in the central device and can be used for planning possibly required subsequent work. The planning of subsequent work consequently can be carried out when the manufactured object is still located in the manufacturing process. This considerably simplifies the planning of subsequent work and makes it possible to save time and lower costs.

IPC: C07C5/333
Filed: 1991-06-03
Abstract: An improved process for dehydrogenation of detergent range normal paraffins contained in a hydrocarbon mixture to produce monoolefins is described. Improvements are obtained by operating over an entire catalyst operating cycle at an average added hydrogen to detergent range hydrocarbon ratio of from about .5 to about 1.9. The improved process is operated in a substantially adiabatic, plug flow reactor at a suitable catalyst bed inlet temperature not greater than about 450 DEG C. The process provides improved tolerance for initial excess catalyst bed activity, allowing desirable catalyst operating cycle lengths to be obtained with more favorable operating conditions.

Abstract: Production of biopharmaceuticals from CHO cells requires generation of master-, working- and post-production cell banks of high quality, partly under GMP conditions. An optimal cryopreservation strategy is needed for each new production cell line, particularly with regard to the desire to establish production processes that are completely devoid of serum or even any animal components and to ensure robust thaw performance for reliable production. Here we describe a novel strategy employing flow cytometric (FC) analysis of Annexin V-stained cells for high-throughput characterization of CHO cell banks. Our data show that this method enables evaluation of a cryopreservation procedure just 6 h after thaw.
