Particular aspects provide electrokinetically-generated fluids (e.g., electrokinetically-generated gas-enriched fluids and solutions), and therapeutic compositions and methods comprising use thereof in treating at least one symptom of cystic fibrosis. In particular embodiments, at least one symptom of cystic fibrosis treated by the present invention include inhibition of Pseudomonas infection, synergy with tobramycin (including TOBI) for use against bacterial infection, and synergy with a bronchiodilator. In particular embodiments, the electrokinetically-generated fluids or therapeutic compositions and methods comprise combination with other therapeutic agents (e.g., antibiotics, albuterol, budesonide, etc.). In certain aspects, the methods comprise regulating or modulating intracellular signal transduction by modulation of at least one of cellular membranes, membrane potential, membrane proteins such as membrane receptors, including but not limited to G protein coupled receptors, and intercellular junctions (e.g., tight junctions, gap junctions, zona adherins and desmasomes).

The invention provides methods, cells and constructs for optical measurement of membrane potential. These methods can be used in cells that are not accessible to presently available methods using electrodes. The methods can be directed to, for example, high-throughput drug screening assays to determine agents that can affect membrane potential of a target cell.

A hierarchical information processing system is disclosed having a plurality of artificial neurons, comprised of binary logic gates, and interconnected through a second plurality of dynamic artificial synapses, intended to simulate or extend the function of a biological nervous system. The system is capable of approximation, autonomous learning and strengthening of formerly learned input patterns. The system learns by simulated Synaptic Time Dependent Plasticity, commonly abbreviated to STDP. Each artificial neuron consisting of a soma circuit and a plurality of synapse circuits, whereby the soma membrane potential, the soma threshold value, the synapse strength and the Post Synaptic Potential at each synapse are expressed as values in binary registers, which are dynamically determined from certain aspects of input pulse timing, previous strength value and output pulse feedback.

Provided are electrokinetically-altered fluids (e.g., gas-enriched (e.g., oxygen-enriched) electrokinetic fluids) comprising an ionic aqueous solution of charge-stabilized gas-containing nanostructures in an amount sufficient to provide, upon contact with a cell, modulation of at least one of cellular membrane potential and cellular membrane conductivity. Further provided are the methods of making the electrokinetically-altered ionic aqueous fluid compositions. Particular aspects provide for regulating or modulating intracellular signal transduction associated by modulation of at least one of cellular membranes, membrane potential, membrane proteins such as membrane receptors, including but not limited to G-Protein Coupled Receptors (GPCR), and intercellular junctions (e.g., tight junctions, gap junctions, zona adherins and desmasomes). Other embodiments include particular methods of producing the electrokinetically-altered fluids. The electrokinetically-altered fluid compositions and methods of producing the fluid include electrokinetically-altered ionic aqueous fluids optionally in the form of solvated electrons stabilized, at least in part, with molecular gas (e.g., oxygen).
