  • Publication number: 20200138983
    Abstract: The present disclosure provides a cancer-specific or tissue specific targeting theranostic capsule using hepatitis E viral nanoparticle (HEVNP) to enhance the accuracy of cancer diagnosis in endoscopic examinations, as well as treatment, for example hyperthermia treatment, after diagnosis. The present disclosure also provides a method of delivering a theranostic agent using the endoscopic apparatus, as well as a non-transitory computer readable medium storing a program that causes a computer to execute the method of the present invention.

  • Publication number: 20200054216
    Abstract: A new generation of precision medicine with interfaces processing the predictive feedback over the course of hyperthermia treatment sessions is provided. Implementation of MR-thermometry measurements and real-time spatial imaging can resolve many of the limiting factors currently associated with hyperthermia treatment. More significantly, implementation of artificial intelligence (machine learning) mediated image analysis and database construction can provide the international community with standards for monitoring, and thermal dose calibration.

  • Publication number: 20190031720
    Abstract: Modified capsid proteins containing at least a portion of hepatitis E virus (HEV) open reading frame 2 (ORF2) having one or more cysteine residues in a surface variable loop or the C-terminus of HEV ORF2, or a portion thereof, are provided. The modified capsid proteins can be used to form hepatitis E virus (HEV) virus like particles (VLPs) having cysteine functional groups exposed on the outer-surface. The exposed cysteine functional groups can be modified via their thiol reactive group. For example, a bioactive agent, such as a cell-targeting ligand, can be conjugated to the one or more cysteines for targeted delivery of chemically activated nanocapsids.

  • Patent number: 9644038
    Abstract: The present invention provides a nanodisc with a membrane scaffold protein. The nanodisc includes a membrane scaffold protein, a telodendrimer and a lipid. The membrane scaffold protein can be apolipoprotein. The telodendrimer has the general formula PEG-L-D-(R)n, wherein D is a dendritic polymer; L is a bond or a linker linked to the focal point group of the dendritic polymer; each PEG is a poly(ethylene glycol) polymer; each R is and end group of the dendritic polymer, or and end group with a covalently bound hydrophobic group, hydrophilic group, amphiphilic compound, or drug; and subscript n is an integer from 2 to 20. Cell free methods of making the nanodiscs are also provided.
