Abstract: Provided herein are compositions, methods, and devices for the treatment and prevention of atrial fibrillation (AF) using gene therapy techniques. In particular, oxidative stress (OS) and parasympathetic nervous system signaling are inhibited to prevent and/or reverse the electrical remodeling that underlies AF.

Abstract: Disclosed herein are pharmaceutical compositions and methods for inhibiting oxidative stress in a subject having atrial or ventricular arrhythmias, ventricular failure or heart failure. The methods include administering an effective amount of a NOX2 inhibitor agent to the subject, wherein said administering is under conditions such that a level of oxidative stress in myocardial tissue is reduced or eliminated. The pharmaceutical compositions include a NOX2 inhibitor agent.

Abstract: Medical devices comprising applicators that present a microneedle array and a separate electroporation array configured to simultaneously contact a tissue surface, a fluidic system connected to the microneedle array, and an electronic system connected to the electroporation array, for the coordinated delivery of a fluid biologic and electroporation energy to a tissue.

Abstract: A conversation for simulation by an artificial intelligence-based tutor is automatically generated. The conversation relates to content on which the artificial intelligence-based tutor is being trained. The automatically generating the conversation includes automatically generating inputs from a simulated student regarding the content, and automatically generating on behalf of the artificial intelligence-based tutor expected responses to the inputs generated from the simulated student. The conversation is provided as an output to be input to the artificial intelligence-based tutor for simulation by the artificial intelligence-based tutor.

Abstract: Provided herein are materials, methods, and devices for the targeted delivery of agents. In particular, provided herein are materials, methods, and devices for the targeted delivery of agents to the atria or ventricles of the heart.
