Abstract:
The invention provides immunotherapeutic and prophylactic bacteriophage viral-like particle (VLPs) which are useful in the treatment and prevention of human papillomavirus (HPV) infections and related disorders, including cervical cancer and persistent infections associated with HPV. Related compositions (e.g. vaccines), nucleic acid constructs, and therapeutic methods are also provided. VLPs and related compositions of the invention induce high titer antibody responses against HPV L2 and protect against HPV challenge in vivo. VLPs, VLP-containing compositions, and therapeutic methods of the invention induce an immunogenic response against HPV infection, confer immunity against HPV infection, protect against HPV infection, and reduce the likelihood of infection by HPV infection.
Abstract:
Various embodiments provide materials and methods for synthesizing protocells for use in targeted delivery of cargo components to cancer cells. In one embodiment, the lipid bilayer can be fused to the porous particle core to form a protocell. The lipid bilayer can be modified with targeting ligands or other ligands to achieve targeted delivery of cargo components that are loaded within the protocell to a target cell, e.g., a type of cancer. Shielding materials can be conjugated to the surface of the lipid bilayer to reduce undesired non-specific binding.
Abstract:
The present invention is directed to methods of diagnosing the presence or absence of a bacterial infection in a patient, in particular, a tuberculosis infection, by measuring exhaled, isotopically labeled nitrogen gas after administration of isotopically labeled isoniazid.
Abstract:
Certain embodiments of the present invention include a system and methods for providing a video image display technology with separate video perspective displays. Each perspective display may be tailored and adapted in real-time to the differing roles of each user, e.g., one or more medical professionals of a surgical team. As an example, one video perspective display may be a panoramic perspective display for a primary surgeon and a second video perspective may be a detailed perspective display for the surgical assistant.
Abstract:
A method of preparation of M-N—C catalytic material utilizing a sacrificial support approach and using inexpensive and readily available metal precursors and carbendazim (CBDZ) as the carbon source is described.
Abstract:
The present invention is directed to novel non-invasive diagnostic tools/compounds comprising a cyclic peptide wherein the compound binds to a MSH receptor to image and treat cancers, especially, melanoma, including metastatic melanoma in vivo. The present invention represents a clear advance in the art which presently relies on tissue biopsy for diagnoses of these cancers. The novel imaging probes are capable of detecting cancerous melanoma cells, as well as their metastatic spread in tissues. This represents a quantum step forward in the diagnosis and treatment of melanoma, including metastatic melanoma using non-invasive molecular imaging techniques. The novel probes of the present invention will also be useful to initiate therapy for melanoma as well as monitor patients response to chemotherapy treatments and other interventions or therapies used in the treatment of melanoma/metastatic melanoma. Compounds according to the present invention may be used as diagnostic tools for a number of conditions and diseases states as well as therapeutic agents for treating such conditions and disease states.
Abstract:
Photon-based radiosurgery is widely used for treating local and regional tumors. The key to improving the quality of radiosurgery is to increase the dose falloff rate from high dose regions inside the tumor to low dose regions of nearby healthy tissues and structures. Dynamic photon painting (DPP) further increases dose falloff rate by treating a target by moving a beam source along a dynamic trajectory, where the speed, direction and even dose rate of the beam source change constantly during irradiation. DPP creates dose gradient that rivals proton Bragg Peak and outperforms Gamma Knife® radiosurgery.
Abstract:
The present invention relates to a system and method for controlling peptide display valency on virus-like particles (VLPs), especially including MS2 VLPs. In this method, large amounts of wild-type and low quantities of single-chain dimer coat proteins may be produced from a single RNA. Valency is controlled in immunogen (vaccine) production by providing a system that allows the production of large amounts of wild-type and low quantities of single-chain dimer coating proteins from a single RNA, allowing facile adjustment of display valency levels on VLPs, especially MS2 VLPS over a wide range, from few than one—on average—to as many as ninety per particle. This facilitates the production of immunogens and vaccines, including VLPs exhibiting low valency. Nucleic acid constructs useful in the expression of virus-like particles are disclosed, comprised of a coat polypeptide of MS2 modified by insertion of a heterologous peptide, wherein the heterologous peptide is displayed on the virus-like particle and encapsidates MS2 niRNA. Nucleic acid constructs are also disclosed which are useful in the expression of virus-like particles comprised of a coat polypeptide of PP7 modified by insertion of a heterologous peptide, wherein the heterologous peptide is displayed on the virus-like particle and encapsidates PP7 mRNA.
