Studies on the cellular and subcellular levels promote elucidation of the fundamental principles of formation of effective neuronal systems from cell units. To estimate the interrelations between electrical activity of neuronal networks and processes realized on the cellular level, we need to adequately understand the general patterns of behavior of populations of interneurons, which are components...
A quantitative spectrophotometric method has been developed for determining the impurity of isonaphthazarin in samples of tetraxolin. The relative error of determination is about 1.0% at a confidence probability of P = 0.95%. The procedure is recommended for the quantitative control of the possible impurity of isonaphthazarin in the parent substance of tetraxolin.
