It is demonstrated that by two-dimensional spin-diffusion powder NMR spectroscopy it is possible to determine accurately relative interaction-tensor orientations. This technique is applied to the determination of the asymmetry of the potential for the proton exchange across the hydrogen bonds in cry
The burst pattern of electrical activity recorded from pancreatic B-cells in response to 11 mM glucose shows a large islet to islet variability. The relationship between burst frequency and glucose sensing (the threshold for electrical activity and the graded increase in electrical response to gluco
