Use of dianhydrogalactitol or derivatives or analogs thereof for treatment of pediatric central nervous system malignancies

The use of dianhydrogalactitol provides a novel therapeutic modality for the treatment of malignancies of the central nervous system in pediatric patients, including glioblastoma multiforme (GBM) high grade glioma, and medulloblastoma. Dianhydrogalactitol acts as an alkylating agent on DNA that creates N.sup.7 methylation and that can induce double-stranded breaks in DNA. Dianhydrogalactitol is effective in suppressing the growth of cancer stem cells and is active against tumors that are refractory to temozolomide, cisplatin, and tyrosine kinase inhibitors; the drug acts independently of the MGMT repair mechanism. Dianhydrogalactitol can be used together with other anti-neoplastic agents (e.g. cisplatin) and can possess additive or super-additive effects.

Neutron capture therapy system comprising a beam shaping assembly configured to shape a neutron beam

A neutron capture therapy system includes an accelerator for generating a charged particle beam, a neutron generator for generating a neutron beam having neutrons after irradiation by the charged particle beam, and a beam shaping assembly for shaping the neutron beam. The beam shaping assembly includes a moderator and a reflecting assembly surrounding the moderator. The neutron generator generates the neutrons after irradiation by the charged particle beam. The moderator moderates the neutrons generated by the neutron generator to a preset energy spectrum. The reflecting assembly includes a plurality of reflectors configured to guide deflected neutrons back to the neutron beam and a supporting member to support the plurality of reflectors. A lead-antimony alloy is for the reflecting assembly to mitigate a creep effect that occurs when only a lead material is for the plurality of reflectors, thereby improving the structural strength of a beam shaping assembly.

In some embodiments, the method comprises reducing the ability of an immune suppressor cell (e.g., MDSC) to migrate to the microenvironment of the cancer. In some embodiments, the method further comprises suppressing the migration of the immune suppressor cell to a non-malignant cell and/or suppressing the malignant transformation of the non-malignant cells.

Non-invasive energy upconversion methods and systems for in-situ photobiomodulation

Products, compositions, systems, and methods for modifying a target structure which mediates or is associated with a biological activity, including treatment of conditions, disorders, or diseases mediated by or associated with a target structure, such as a virus, cell, subcellular structure or extracellular structure. The methods may be performed in situ in a non-invasive manner by placing a nanoparticle having a metallic shell on at least a fraction of a surface in a vicinity of a target structure in a subject and applying an initiation energy to a subject thus producing an effect on or change to the target structure directly or via a modulation agent. The nanoparticle is configured, upon exposure to a first wavelength λ.sub.1, to generate a second wavelength λ.sub.2 of radiation having a higher energy than the first wavelength λ.sub.1. The methods may further be performed by application of an initiation energy to a subject in situ to activate a pharmaceutical agent directly or via an energy modulation agent, optionally in the presence of one or more plasmonics active agents, thus producing an effect on or change to the target structure. Kits containing products or compositions formulated or configured and systems for use in practicing these methods.
