Abstract: An electrochemical cell that oxidizes a solution provides a continuous and stable supply of an oxidizing ion solution to a fixture or vessel used for the purposes of decontaminating metal and metal alloys. The electrochemical cell includes an anode compartment that oxidizes the solution in nitric acid or methane sulfonic acid at a rate equal to or greater than a rate of reduction, or generates the oxidizing ions prior to use in a batch. The electrochemical cell is part of a larger system that facilitates online measurement system which measures the oxidizing ion solution and the dissolved PuO2, UO2, AmO2, other radionuclides, or other contaminates in real-time. Solution decontamination system removes the dissolved PuO2/UO2/AmO2, other radionuclides, or other contaminates from the oxidizing ion solution, real time acoustic monitoring of the thickness of the surface being contaminated, and automation of a delivery system facilitates flow between surface and electrochemical cell.

Abstract: Methods of inducing bradycardia (slowing a heart rate) in a subject in need thereof, treating a medical condition in which inducing bradycardia (slowing a heart rate) is desirable or beneficial in a subject in need thereof and/or treating a medical condition associated with cardiac arrhythmia, are provided. The methods are effected by blocking SK4 channel in SAN cell of the subject and/or by administering to the subject a therapeutically effective amount of a blocker of an SK4 channel. A method of identifying candidate compounds for treating an arrhythmic cardiac disorder, by identifying compounds that reduce a pacing rate of the SAN cells is also provided.
