  • Patent number: 11667946
    Abstract: The present invention relates to the field of diagnostics and more particularly to the detection of beta-hemolytic pathogens. More specifically, the present invention relates to the rapid and accurate detection of beta-hemolytic pathogens using sterically-stabilized liposomes.
    Type: Grant
    Filed: October 22, 2020
    Date of Patent: June 6, 2023
    Assignee: Temasek Life Sciences Laboratory Limited
    Inventors: Rongji Sum, Muthukaruppan Swaminathan, Ian Cheong
  • Patent number: 11331272
    Abstract: Hyperstable liposome comprising an anti-mitotic agent, one or more anions and one or more cations entrapped in the inner milieu, wherein the entrapped anti-mitotic drug is released at a slow rate that is less than 0.6% in 12 hours or less than 5% in 8 hours when the liposomes are suspended in 600 mM sucrose. These liposomes are useful in the treatment of cancer. In particular, HEPC:Chol:DSPE-PEG2000 (50:45:5) liposomes comprising BI 2536 and citrate:phosphate in a ratio of 1:3.

  • Patent number: 10325183
    Abstract: An improved system and method for digital image classification is provided. A host computer having a processor is coupled to a memory storing thereon reference feature data. A graphics processing unit (GPU) having a processor is coupled to the host computer and is configured to obtain, from the host computer, feature data corresponding to the digital image; to access, from the memory, the one or more reference feature data; and to determine a semi-metric distance based on a Poisson-Binomial distribution between the feature data and the one or more reference feature data. The host computer is configured to classify the digital image using the determined semi-metric distance.

  • Publication number: 20150306184
    Abstract: Clostridium novyi is an obligate anaerobe that can infect hypoxic regions within experimental tumors. We found that mice bearing large, established tumors were often cured when treated with C. novyi plus a single dose of liposomal doxorubicin. The secreted factor responsible for this phenomenon was identified and, surprisingly, proved to be a member of the lipase family. The gene encoding this protein, called liposomase, has the potential to be incorporated into diverse therapeutic methods to deliver specifically a variety of chemotherapeutic agents to tumors.
