Devices, systems and methods are disclosed for treating or preventing a developmental disorder, such as attention-deficit hyperactivity disorder (ADHD), an autism spectrum disorder, Asperger syndrome, childhood disintegrative disorder, overactive disorder, pervasive developmental disorder. A device comprises an electrode having a contact surface for contacting an outer skin surface of a patient and a power source coupled the electrode. The power source generates and transmits an electrical impulse having a frequency of about 1 kHz to about 20 kHz through the contact surface and the outer skin surface to a nerve within the patient. The electrical impulse is sufficient to modify the behavioral disorder in the patient.

An apparatus for damaging or killing cancer cells in a living human body comprising a temperature monitoring apparatus that allows a user to monitor the temperature of a tumor and the surrounding tissue, such that when the tumor is at a temperature greater than the surrounding tissue, either because that is the nature of the tumor or because the tumor temperature has been raised through the introduction of an organic substance, an energy source may be used to elevate the temperature of the tumor above a critical temperature that damages or kills the tumor, but does not kill the surrounding non-cancerous cells because they start off at a lower temperature and are never allowed to go above the critical temperature that damages or kills those non-cancerous cells.

Methods, devices, and processor-readable storage media for a radio frequency-based (RF-based) therapeutic for the treatment of neurological conditions are provided herein. An example device includes one or more antenna elements sized and configured for one or more operational frequencies; at least one RF generator-controller unit; at least one switching element coupled with at least a portion of the one or more antenna elements; and a distributed functional architecture and/or at least one cable, wherein the distributed functional architecture and/or the at least one cable facilitates transmission of one or more of RF emissions, one or more antenna control voltages, and one or more system-control signals between the at least one RF generator-controller unit and the at least one switching element in connection with at least a portion of the one or more antenna elements.

Magnetic nanoparticles for use in a magnetic hyperthermia therapeutic treatment, prophylactic treatment or diagnosis method, wherein the magnetic nanoparticles are administered to a body part of an individual and the body part is exposed to a magnetic field oscillating at a high frequency and at a medium and/or low frequency, wherein the high frequency is 1 MHz at the most, the medium frequency is lower than the high frequency, and the low frequency is lower than the high frequency and lower than the medium frequency when it is present.

A method and apparatus generate electrical currents and/or voltage in tissue using particles composed of liquid crystals and magnetic particles.

The present wireless remote control device is a type of equipment with non-tethered optical stimulation. The characteristic of this device is designed to utilize a magnetic resonance technique to modify the deficits of the conventional magnetic induction or radio-frequency power source. Compared to the other devices of photostimulation, the advantages are as follow: there is a strong and even electromagnetic power; the cost is cheaper than the previous others; the device uses the receiver coil on an animal's head to receive the magnetic power from the transformation of the electrical power in the outside big coil, and thus the weight of the receiver coil on the head is very light. The light and miniaturized coil on the head without battery could give animals more convenience in freely movement, and the behavior of animals can be controlled by the effective extent of the electromagnetic field through photostimulation.
