Since transmembrane sodium gradient is essential to many cell functions, there is continuing interest in methods that differentiate intracellular and extracellular Na+. In the kidney, shift reagent (SR) aided 23Na magnetic resonance spectroscopy (MRS) has been successfully used only in isolated cells, tubules, and the perfused organ. In this report, we(More)
The project this work is part of aims at investigating and developing robotic tools and multisensory cues to assist human micromanipulation. In this context my thesis describes the development of a haptic interface for z-axis micro-assembly tasks which require three degrees of freedom. First specifications for operating in the micro-domain as well as human(More)
