  • Patent number: 10526661
    Abstract: In accordance with the invention, a novel gene translocation, (5q32, 6q22), in human non-small cell lung carcinoma (NSCLC) that results in a fusion proteins combining part of CD74 with Proto-oncogene Tyrosine Protein Kinase ROS Precursor (ROS) kinase has now been identified. The CD74-ROS fusion protein is anticipated to drive the proliferation and survival of a subgroup of NSCLC tumors. The invention therefore provides, in part, isolated polynucleotides and vectors encoding the disclosed mutant ROS kinase polypeptides, probes for detecting it, isolated mutant polypeptides, recombinant polypeptides, and reagents for detecting the fusion and truncated polypeptides.

  • Patent number: 10458870
    Abstract: A pressure sensor may measure gas or liquid pressure. A chamber may have an inlet that receives the gas or liquid. A flexible diaphragm may be within the chamber that has a surface exposed to the gas or liquid after it flows through the inlet. A pressure sensor system may sense changes in the flexible diaphragm caused by changes in the pressure of the gas or liquid. A pressure-insensitive sensor system may sense changes in the flexible diaphragm that are not caused by changes in the pressure of the gas or liquid. The pressure-insensitive sensor system may be insensitive to changes in the flexible diaphragm caused by changes in the pressure of the gas or liquid.

  • Patent number: 10438000
    Abstract: The content of each specific image file in a user's backup set (or other type of file set on an endpoint) is analyzed, for example during a backup of the endpoint. Each analyzed image file is categorized based on the results of analyzing its content. The analysis can be in the form identifying one or more objects graphically represented in given image files, and the categorization of image files can be based on these identified graphically represented object(s). Subsequently (for example during a subsequent backup of the endpoint), modifications made to specific ones of the image files in the file set are detected. In response to a quantification of the detected modifications exceeding a specific threshold level, it is adjudicated that a file corruption event has occurred on the endpoint, such as a cryptographic ransomware attack. In response to the adjudication, one or more security actions are taken.

  • Patent number: 10317298
    Abstract: An apparatus (100, 200, 300) and a method for measuring residual torsions of an elongated structure (202) such as a steel cord use a pivot head (102). The pivot head (102) comprises a wheel (104) adapted to guide an elongated structure (202). The wheel (104) is mounted in the pivot head (102) to transmit torques exercised by the elongated structure (202) on the wheel (104) to the pivot head (102). The pivot head (102) is mounted along a pivotal axis (110). This pivotal axis (110) lies in a plane of the wheel (104) and comprises the center of the wheel (104). Sensors (116, 206) measure the torque on the pivot head (102). The pivotal movement of the pivot head (102) around the pivotal axis (110) is limited to an angle range of ±5°, preferably ±3° in order to reach an improved accuracy of the torque measurement.

  • Publication number: 20190127804
    Abstract: Novel gene deletions and translocations involving chromosome 2 resulting in fusion proteins combining part of Anaplastic Lymphoma Kinase (ALK) kinase with part of a secondary protein have been identified herein in human solid tumors, e.g. non-small cell lung carcinoma (NSCLC). Secondary proteins include Echinoderm Microtubule-Associated Protein-Like 4 (EML-4) and TRK-Fusion Gene (TFC). The EML4-ALK fusion protein, which retains ALK tyrosine kinase activity, was confirmed to drive the proliferation and survival of NSCLC characterized by this mutation. The invention therefore provides, in part, isolated polynucleotides and vectors encoding the disclosed mutant ALK kinase polypeptides, probes for detecting it, isolated mutant polypeptides, recombinant polypeptides, and reagents for detecting the fusion and truncated polypeptides.

  • Publication number: 20190128889
    Abstract: The invention provides the identification of the presence of polypeptides with ROS kinase activity in mammalian lung cancer. In some embodiments, the polypeptide with ROS kinase activity is the result of a fusion between a ROS-encoding polynucleotide and a polynucleotide encoding a second (non-ROS) polypeptide. Three different fusion partners of ROS are described, namely proteins encoded by the FIG gene, the SLC34A2 gene, and the CD74 gene. The invention enables new methods for determining the presence of a polypeptide with ROS kinase activity in a biological sample, methods for screening for compounds that inhibit the proteins, and methods for inhibiting the progression of a cancer (e.g.
