Provided are a contrast agent for optical imaging, a use thereof and an apparatus using the same. The contrast agent for optical imaging of the present disclosure allows optical imaging without requiring a fluorophore or a luminophore. As a result, the optical images can be acquired without changing the physicochemical properties of a substrate. The contrast agent for optical imaging of the present disclosure may be used as an optical/nuclear bimodal imaging contrast agent for many applications, and allows radiation therapy as well as monitoring of a therapeutic effect thereof through optical imaging at the same time. Further, when a fluorophore is attached thereto, light emission may be enhanced without energy input from outside since light is emitted from the fluorophore, thereby increasing luminescence intensity and improving tissue penetration.

Disclosed are methods of detecting eosinophil degranulation in the respiratory tract of subjects. Also, disclosed are methods of producing medical images of the respiratory tract of subjects. The method can include administering radiolabeled heparin to the respiratory tract of subjects, wherein the radiolabeled heparin binds to one or more eosinophil granule protein in the mucosal tissue of the respiratory tract.

Disclosed are methods of preventing, treating, or diagnosing in a subject a disorder in protein folding or aggregation, or amyloid formation, deposition, accumulation, or persistence consisting of administering to said subject a pharmaceutically effective amount of inositol stereoisomers, enantiomers or derivatives thereof.

Provided are aptamers able to bind to ligands associated with cancer cells. The ligands may particularly be associated with brain cancers, such as gliomas. The aptamers may be used therapeutically for the prevention and/or treatment of such cancers. Aptamers may be associated with anti-cancer agents, or with detection moieties. Also provided are pharmaceutical compositions and methods of treatment employing such aptamers.

In making an optical component, one or more portions of a substrate's surface are patterned. At least a region of the substrate's surface is coated in negative photoresist, the region encompassing said portions. The negative photoresist becomes undevelopable when exposed to light. Light which forms a grating structure is projected over each of the portions. Light of substantially uniform intensity over the entirety of the region but for the portions, thereby leaving the negative photoresist outside of the portions undevelopable. The negative photoresist is developed so as to embody the grating structure in the photoresist covering the portions. The substrate's surface is patterned to impose the grating structure on the substrate's surface from the developed photoresist; the undevelopable photoresist inhibits patterning of the surface region outside of the portions. The optical component comprises the patterned substrate.

The present disclosure relates to compounds useful for the detection or modulation of target nucleic acids, including DNA and RNA. The present disclosure further relates to methods for treatment of trinucleotide repeat disorders, which can include administration of oligonucleotide analogues that can bind pathogenic nucleotide repeats in DNA or RNA.

Also disclosed are methods

This invention relates new radiopharmaceutical conjugates for use in improved methods of diagnosis and treatment of cancer. The radiopharmaceutical conjugate comprises, in sequence: a metabolite that targets tumour cells, bound to a chelating agent capable of containing a radionuclide, bound to a linker capable of binding with an EPR agent in vitro or in vivo; or a chelating agent capable of containing a radionuclide, bound to a metabolite that targets tumour cells, bound to a linker capable of binding with an EPR agent in vitro or in vivo. The radiopharmaceutical conjugates of the present invention provide active and passive targeted radio nuclide delivery systems that can help to improve the biodistribution and pharmacological toxicity of the radiopharmaceuticals used for the diagnosis and therapy of cancer.

Disclosed are compositions and methods for diagnosing eosinophilic esophagitis in a subject. Also disclosed are methods for monitoring the course of eosinophilic esophagitis in a subject before, during, and after treatment.

Disclosed are methods of imaging a site in a heart of a subject to detect cardiovascular disease that involve stressing a subject, administering to the stressed subject an effective amount of a radionuclide-labeled chelator-glucose analog conjugate, and imaging the heart of the subject by detecting a signal generated by the conjugate in the heart of the subject. Also disclosed are methods of imaging a peripheral blood vessel in a subject by using a detectable amount of a radionuclide-labeled chelator-glucose analog conjugate. Also disclosed are methods of distinguishing a false positive nuclear cardiology scan from a true positive nuclear cardiology scan, methods of diagnosing congestive heart failure or cardiac ischemia that involve imaging a subject that has been administered a radionuclide-labeled chelator-glucose analog conjugate, and methods to distinguish viable from nonviable myocardium.
