Abstract: Described herein are functional cell assays and methods for selecting a personalized anti-cancer treatment regimen that can improve treatment of cancer in a subject, identify resistance of the subject's cancer to one or more anti-cancer agents and/or validate the current drug treatment strategy.

Abstract: A system for supplying hydrogen gas to a lighter-than-air (LTA) vehicle includes a manifold having multiple vessels. Each vessel has a first chamber that is separated from a second chamber by a barrier. A trigger assembly integrated with the barrier allows a liquid to be combined with a reactant and a catalyst in the second chamber to form a chemical reaction to generate hydrogen gas. A pressure relief valve located on each vessel opens to allow the hydrogen gas to exit when a predetermined pressure is reached, and the hydrogen gas is supplied to the LTA vehicle connected to the manifold.
