... 20–60 min of inactivity. We hypothesized that an exercise-induced increase in blood volume between muscle fibers creates regions of low refractive index fluid between high refractive index muscles, thereby increasing light scattering. We documented pre- and post-contraction perfusion by injecting...

... to demonstrate that the calcium channels that are blocked by ω-conotoxin are those that are required for secretion of peptide hormones. In the terminals of the neurohypophysis, excitation is coupled to secretion, and the secretory event is accompanied by large and rapid changes in light scattering...

... vesicles. It also enables accurate measurements of surface charge properties of isolated granules and plasma membranes. Recently, a fast, total intensity light-scattering change, sensitive to many of the factors that influence secretion, has been detected in neurosecretory terminals. Here a slower...
