  • Publication number: 20200071763
    Abstract: The present disclosure relates to methods for amplifying nucleic acids that avoid problems associated with primer-dimer formation. The present methods are referred to herein as dimer avoided multiplex polymerase chain reaction (dam-PCR). The methods disclosed herein generally comprise the steps of reverse transcribing at least one first strand of DNA, for example cDNA from an RNA sample, wherein each first strand of DNA incorporates a reverse common primer binding site; selecting each first strand of DNA; synthesizing at least one second strand of DNA from each of the at least one first strand of DNA, wherein each second strand of DNA incorporates a forward common primer binding site; selecting each second strand of cDNA; and amplifying the DNA strands using common primers. Alternatively, the method may be performed using a gDNA template.

  • Patent number: 10529442
    Abstract: The present invention pertains to methods for determining the change in the immune repertoire of an individual suffering from disease or undergoing therapy for the treatment of a disease. The methods use the difference between the change in the level of immune cell diversity seen in an individual before, during or after a health event to determine the effect of the disease, or the effect of a treatment regime, on the individual. The difference in the level of immune cell diversity is referred to as the Delta Index and is defined as the quantitative and qualitative change (gain or loss of clones) of an individual's most dynamic immune cells over time.

  • Patent number: 10345320
    Abstract: Embodiments of the present disclosure generally pertain to systems and methods for performing amplicon rescue multiplex polymerase chain reaction (arm-PCR). In one embodiment, the system comprises a processor and a reader coupled to a control element. The control element is configured to control the operation of the processor and the reader based on a variety of settings. The processor is configured to receive a self-contained cassette for performing PCR amplification of DNA and/or RNA obtained from an organic specimen. The processor engages with the cassette and manipulates reagents within the cassette in order to amplify and detect the DNA from the specimen. The processor also causes the cassette to deposit the DNA on a microarray within the cassette. The reader is configured to receive the cassette after it has been processed by the processor and to capture an image of the microarray for transmission to the control element as test data.

  • Publication number: 20190207783
    Abstract: A data forwarding method is provided for a data forwarding apparatus. The method includes, when a first port receives a to-be-forwarded data packet, executing a network adapter driver corresponding to the first port to read the to-be-forwarded data packet from a network adapter cache corresponding to the first port. The network adapter cache stores address forwarding information obtained from an operating system kernel bridge. The method also includes searching the address forwarding information in the network adapter cache for address forwarding information corresponding to the data packet and, when the address forwarding information corresponding to the data packet is found, determining a target network adapter driver for forwarding the data packet based on the found address forwarding information, and directly sending the data packet to the target network adapter driver, such that the target network adapter driver forwards the data packet through a second port.

  • Patent number: 10230411
    Abstract: A method and apparatus for distinguishing voice signals that are played together over the same speaker employs spectral reshaping of one or more of the audio signals. The spectral reshaping shifts modifies the timber of the voice signal while not modifying the pitch of the voice signal. Additional techniques can be used to further distinguish voice signals, such as dynamic gain offset and frequency shifting. After processing one or more signals to spectrally reshape them, they can be played over the same speaker. A user hearing the resulting acoustic signal will be more able to distinguish between the multiple voice signals being played.
