One embodiment is directed to a method for treating the nervous system of a patient, comprising: determining a desired nervous system functional modulation to be facilitated by sonogenetic intervention; selecting targeted neuroanatomy for achieving the desired functional outcome with sonogenetic intervention; and delivering an effective amount of polynucleotide comprising a sound-responsive opsin protein which is expressed in neurons of the targeted neuroanatomy, wherein delivering comprises systemically injecting the effective amount of polynucleotide and facilitating diffusive access to the targeted neuroanatomy using focused ultrasound energy.

In an aspect of the present disclosure there is provided a method for reversibly stimulating neuronal cells, said method comprising activating mechanosensitive ion channels of neuronal cells expressing said channels by exposing said cells to an ultrasound stimulus.

An embodiment of a system includes a power source and at least two electrode assembles. The power source that an output current that alternates between a maximum current value and a minimum current value; a pair of electrode assemblies. Each electrode assembly is configured to be held in contact with a skin layer of a user. Additionally, each electrode assembly includes an electrode that is coupled to the power source to receive the output current from the power source. At least one of the electrode assemblies in the pair includes a medium that carries an active agent having a charge, the medium being provided on the at least one electrode assembly to enable the output current to repel the active agent into the skin layer for a duration in which the output current has a polarity that is the same as a polarity of the active agent.

Systems and methods of stimulating or activating fluids for use in wound treatment systems.

A phonophoretic cannabidiol composition comprises an amount of cannabidiol, an amount of a glucose source, such as honey, an amount of aloe vera, and amounts of one or more of glucosamine, methylsulfonylmethane, and chondroitin. A transdermal delivery system for administration of a phonophoretic cannabidiol composition includes a phonophoretic cannabidiol composition, a laser generator comprising an emitter which generates and directs a laser beam to the treatment area, and an ultrasound generator comprising a transducer which generates and transmits a plurality of ultrasonic waves to the treatment area. A method for transdermal delivery of a phonophoretic cannabidiol composition includes selecting laser pretreatment parameters, directing a laser beam to the treatment area, applying an amount of a phonophoretic cannabidiol composition to a treatment area, selecting ultrasonic treatment parameters, and, transmitting a plurality of ultrasonic waves to the treatment area.

A method of monitoring viability of stem cell-derived cells used in stem cell therapy comprises introducing one or more stem cell-derived cells to a cell culture media, introducing one or more nanoprobes to the cell culture media, whereby the one or more stem cell-derived cells are transfected with the one or more nanoprobes, and detecting an optical signal from the one or more nanoprobes after transfection. The method may further comprise introducing the one or more transfected stem cell-derived cells to a subject and detecting the optical signal from the one or more nanoprobes in vivo. The one or more stem cell-derived cells may include a stem cell.

Provided herein are electrotransfer devices for delivering agents (e.g., nucleic acid vectors) to target cells. Also provided are methods of electrotransfer of therapeutic agents.

Disclosed herein are nanoparticles comprising one or more Human papillomavirus (HPV) antigen and nucleic acid molecules encoding the same. Also disclosed herein is a method of treating a HPV infection or treating or preventing a disease or disorder associated therewith in a subject in need thereof, by administering the nanoparticles, or encoding nucleic acid molecules, to the subject.

Compositions, methods, and kits relating to ultrasound targeted nanobubble compositions are disclosed. The nanobubble compositions comprise a hollow core containing at least one gas; at least one therapeutic agent disposed in the hollow core; a polymer shell encircling the hollow core; and at least one targeting agent incorporated in the polymer shell. Methods of producing and using the nanobubble compositions are also disclosed.

The present invention provides for a dosing schedule for the intratumoral delivery of an immunostimulatory cytokine in combination with systemic delivery of a checkpoint inhibitor. In particular, it provides delivery of a plasmid encoding the immunostimulatory cytokine, e.g., IL-12, using intratumoral electroporation, and the systemic delivery of a PD-1 antagonist.
