METHOD AND SYSTEM FOR THERMAL STIMULATION OF TARGETED NEURAL CIRCUITS FOR THE TREATMENT OF PARKINSON'S DISEASE
A method and system for noninvasively treating a neurodegenerative disorder, can involve determining characteristics indicative of physical attributes of a central nervous system, the characteristics including parameters for diminishing adverse impacts of a magnetothermal stimulation treatment for a neurodegenerative disorder with respect to the central nervous system, and applying as a part of the magnetothermal stimulation treatment and based on the characteristics of the physical attributes of the central nervous system, a magnetic field to the brain for a thermal stimulation of neuron cells within the brain.
Heat substrate and/or image enhancement compositions and enhanced tissue ablation methods
Ferritin or iron-based image enhancement agents identify target tissue for treatment or ablation and are heated by microwave absorption. Microwave heat substrates enhance microwave hyperthermal ablation treatment, and may be percutaneously delivered and imaged by x-ray CT during placement of the microwave treatment antenna, allowing more precise positioning and more complete ablation of a tumor site. One method of treating a target tissue uses image-guided delivery of a heat substrate with a reverse-phase change polymer, and may apply energy to fix a mass of the material in the tissue. The fixed polymer may increase hyperthermia, form a thermal boundary, or blockade a vessel or passage so as to reduce or prevent undesired conductive cooling by contiguous tissue, or may deliver a localized treatment drug at the site, upon heating or as it degrades over time.
PHOTODYNAMIC THERAPY METHOD FOR SKIN DISORDERS

SENSITIZING COMPOSITION USING ELECTROMAGNETIC WAVES FOR THERMAL THERAPY OF CANCERS, AND CANCER THERAPY USING SAME
Disclosed are a sensitizing composition for thermal cancer therapy using electromagnetic waves and a method of treating cancer using the composition. The sensitizing composition includes a metal ion, a metal ion-bound material, metal ion-noncovalently bound apotransferrin (transferrin), or a metal ion-noncovalently bound apotransferrin derivative. The sensitizing composition enables selective delivery of the metal ion to tumorous tissue when administered in vivo, and thus the generation of heat in tumorous tissue in which the metal ion accumulates is increased upon thermal cancer therapy using electromagnetic waves, thereby maximizing efficacy of thermal cancer therapy using electromagnetic waves in treating cancer. Thermal therapy using the sensitizing composition effectively treats cancer without pain or side effects and is thus expected to be widely useful in anticancer treatment as monotherapy, and/or in combination with chemotherapy, radiation therapy, or a combination thereof, ultimately increases the potential to cure cancer.
