  • Patent number: 11397762
    Abstract: A domain-specific question answering system receives an end-user's question, identifies relevant information from domain-specific documents, composes a natural-language based response including the relevant information to be provided to the end-user. A knowledge base includes a domain-specific ontology and is built from data structures configured to preserve the hierarchy of the informational elements within the domain-specific documents. The question received from the end-user is analyzed to extract the features and the key phrases which are used to identify the relevant data structures. A pre-trained model that is further trained on domain-specific data is used to identify the sentences that include information responsive to the question. A response to the end-user's question is composed from the sentences. The question answering system also enables validation of the answers provided to the users' questions.

  • Publication number: 20220168261
    Abstract: The present disclosure relates to methods of managing cancer by modulating/inhibiting cap methyltransferase enzyme. The modulation/inhibition is carried out by pharmacological or biological inhibitors, including but not limited to compounds of formula (VIII) or Compound A or A-1. Thus, the present disclosure relates to such inhibitors including compounds of formula (VIII) and their use for management of cancer. In some aspects, the compound of formula (VIII) is Compound 1. The present disclosure also relates to methods of activating B cells or T cells via modulation of cap methyltransferases. The present disclosure also relates to methods of managing cancer with a molecule or biologic that generates unmethylated RNA. The generation of unmethylated RNA activates B cells and presents the RNA to B-cell receptor (BCR). The present disclosure therefore also relates to management of cancer by activating B cells and then adoptively transferring the B cells to exert an anticancer effect.

  • Patent number: 11062220
    Abstract: A virtual cognitive agent (VCA) system comprises social media communication channels integrated with machine cognition engines. The VCA system connects to an external message platform and accesses posted messages. An intent is determined and sentiment analysis is performed on text elements from the intercepted messages to determine handling of the message. The integrated machine cognition engines determine a response to the captured message. The VCA system may access a corpus or exchange data with the originator of the post or another entity to determine the response. The integrated social media communication channels may connect to an external query response platform and communicate the response to the query response platform.

  • Patent number: 10905781
    Abstract: Described herein is a reporter material platform that can be used to directly monitor the drug response in real-time. The reporter material can include an activator element which undergoes a chemical change in response to an immunonological response to a drug, and the chemical change can be detected using a reporter element. The reporter material can include a drug and a reporter element that are physically constrained in a close proximity. The reporter element produces a signal only when the drug induces a direct or indirect physiological change in the tumor or surrounding tissue. The reporter material platform can self-assemble via supramolecular interactions. This reporter material platform can be used to directly monitor the drug response in real-time.

  • Patent number: 10533059
    Abstract: The current invention discloses targeted drug delivery conjugates comprising a targeting moiety linked to a drug via a molecule having an affinity for the targeting moiety. Typically, the conjugate comprises a targeting ligand and a molecule of interest, e.g., a therapeutic agent. The targeting ligand and the molecule of interest are linked to each other via an affinity ligand. The affinity ligand is further covalently or non-covalently linked to a drug or therapeutic agent. The drug can be modified to make it more soluble and so that it cleaves from the linking molecule at the target site.
