  • Patent number: 10815522
    Abstract: Pancreatic adenocarcinoma has the worst overall mortality of any solid tumor, with only 7% of patients surviving after 5 years. To evaluate the clinical implications of genomic alterations in this low cellularity tumor type, we deeply sequenced the genomes of 101 enriched pancreatic adenocarcinomas from patients who underwent potentially curative resections and used non-invasive approaches to examine tumor specific mutations in the circulation of these patients. These analyses revealed somatic mutations in chromatin regulating genes including MLL and ARID1A in 20% of patients that were associated with improved survival. Liquid biopsy analyses of cell free plasma DNA revealed that 43% of patients with localized disease had detectable circulating tumor DNA (ctDNA) in their blood at the time of diagnosis. Detection of ctDNA after resection predicted clinical relapse and poor outcome, and disease recurrence by ctDNA was detected 6.5 months earlier than with standard CT imaging.

  • Patent number: 9506105
    Abstract: A method for amplifying a target nucleic acid present in a sample includes introducing, via an entrance opening of a planar fluidic assembly, a sample containing one or more target nucleic acids into a flow channel of the planar fluidic assembly, the flow channel extending from the entrance opening to an exit vent and having a substantially uniform cross-section. A plurality of nucleic acid primers that are complementary to a portion of the one or more target nucleic acids are disposed at locations within and along the flow channel. The method further includes subjecting the sample introduced into the flow channel to a primer-based amplification reaction using the nucleic acid primers, wherein the primer-based amplification reaction produces amplified product of the one or more target nucleic acids, and retaining the amplified product at one or more of the locations within the flow channel during the primer-based amplification reaction.

  • Patent number: 9447474
    Abstract: Provided is a method for determining the presence or absence of an individual's DNA in a sample containing DNA from two or more contributors. A panel of a plurality of single nucleotide polymorphisms (SNPs) is used. For each SNP in the panel, it is determined whether the minor allele of the SNP is present in the sample, and whether the minor allele is present in the individual's DNA. If the number of minor alleles that are present in the individual's DNA that are also present in the DNA sample is above a predetermined threshold, the individual's DNA is concluded to be present in the sample. Also provided is an array of DNA molecules for use in the method, as well as a method for estimating the number of individuals contributing to a DNA containing sample.

  • Patent number: 9023640
    Abstract: A portable system for real time detection of the presence of an infectious agent in a biological sample employs a reagent which detects the presence of a specific infectious agent in the sample, and emits a detectable signal when the reagent reacts with the sample and detects the presence of the infectious agent. A test cartridge has a reaction chamber for receiving the sample and the reagent. The reaction chamber has a predetermined internal geometry and at least one inner surface. Introducing the sample and the reagent into the test cartridge mixes the sample and the reagent. A testing unit receives the test cartridge, and includes a sensor for detecting an emitted detectable signal. The detection of the emitted detectable signal is indicative of the presence of the infectious agent in the sample.
