摘要:
The present invention is directed to novel non-invasive diagnostic tools to diagnose numerous infectious disease states or conditions. The present invention represents a clear advance in the art which presently relies on tissue biopsy for diagnoses of these disease states. The novel imaging probe is capable of detecting infected cells, as well tissue. This represents a quantum step forward in the diagnosis and staging of NHL using non-invasively molecular imaging techniques. This novel probe will also be useful to monitor patients response to therapeutic treatments and other interventions or therapies used in the treatment of these disease states or conditions. 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. Pharmaceutical compositions are also described.

The present invention is directed to the use of silicic acid to transform biological materials, including cellular architecture into inorganic materials to provide biocomposites (nanomaterials) with stabilized structure and function. In the present invention, there has been discovered a means to stabilize the structure and function of biological materials, including cells, biomolecules, peptides, proteins (especially including enzymes), lipids, lipid vesicles, polysaccharides, cytoskeletal filaments, tissue and organs with silicic acid such that these materials may be used as biocomposites. In many instances, these materials retain their original biological activity and may be used in harsh conditions which would otherwise destroy the integrity of the biological material. In certain instances, these biomaterials may be storage stable for long periods of time and reconstituted after storage to return the biological material back to its original form. In addition, by exposing an entire cell to form CSCs, the CSCs may function to provide a unique system to study enzymes or a cascade of enzymes which are otherwise unavailable.

Using high-throughput screening, in an oxygen-glucose deprivation (OGD) model, isoxsuprine hydrochloride was identified as a potent neuroprotective compound. In an animal middle artery occlusion (MCAO) model of transient focal ischemia, isoxsuprine significantly reduced infarct volume compared to vehicle. The invention, therefore, provides methods of treatment and pharmaceutical compositions that are useful in the treatment and prevention of a wide-variety of ischemia-related injuries, including stroke.
摘要:
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.

Composite orthopedic devices that facilitate spine stabilization, such as: bone screws, rods, plates, interbodies, and corpectomy cages are disclosed. They are designed to provide both strength and load carrying capabilities, while increasing bio-integration of the devices with the surrounding bone tissue. They are constructed of composite layers of allograft and/or autograft bone and a structural material, such as titanium alloy or carbon/graphite fiber composite. Cannulations within the device are loaded with a mixture of stem cells, particles of allograft and/or autograft bone, and bone growth factors, such as BMP-2. The cannulations are connected to the surface of the device via multiple fenestrations that provide pathways to supply the bone/stem cell mixture to the surface, allowing living bone tissue to grow and insure bio-integration. The devices can also have radiofrequency (RF) stimulation implantation within the structure of the implanted device, capable of responding to external RF stimulation of enhanced bone growth.
摘要:
A method for making a heteroepitaxial layer. The method comprises providing a semiconductor substrate. A seed area delineated with a selective growth mask is formed on the semiconductor substrate. The seed area comprises a first material and has a linear surface dimension of less than 100 nm. A heteroepitaxial layer is grown on the seed area, the heteroepitaxial layer comprising a second material that is different from the first material. Devices made by the method are also disclosed.
摘要:
In one embodiment, the invention provides a method of treating a subject suffering from a breast cancer tumor which is non-responsive or intrinsically resistant to anti-estrogen therapy comprising administering a therapeutically effective amount of an inhibitor of alternative (ALT) non-homologous end joining (NHEJ) factor to the subject.In another embodiment the invention provides a method of treating a subject who suffers from a pancreatic cancer which is non-responsive to chemotherapy and/or radiation comprising co-administering a therapeutically effective amount of PARP1 inhibitor and a DNA ligase IIIα inhibitor to the subject. Related diagnostic methods, nucleic acid arrays, devices and kits are also provided.

In one embodiment, the invention provides a method of treating a subject suffering from a Mycobacterium infection by administering to the subject a therapeutically-effective amount of a degradative autophagy agonist or a secretory autophagy antagonist. In another embodiment, the invention provides a method of treating a subject suffering from one or more diseases selected from the group consisting of a Mycobacterium infection, an inflammatory disorder, an immune disorder, a cancer and a neurodegenerative disorder by administering to the subject a therapeutically-effective amount of a TBK-1 antagonist (e.g. BX795 or amlexanox). Related pharmaceutical compositions, diagnostic and screening assays and kits are also provided.

The present invention is directed to novel non-invasive diagnostic tools/compounds to image cancers, especially, melanoma, including metastatic melanoma in vivo. The present compounds exhibit enhanced uptake in cancerous cells and tissue and decreased renal uptake in kidney, evidencing favorable pharmacokinetics of compounds of the present invention. The compounds according to the present invention represent an advance in the diagnosis and treatment of melanoma, including metastatic melanoma using non-invasive molecular imaging techniques. The novel probes of the present invention are also useful for initiating 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.
