It is almost impossible to imagine life without things we grew up with, so it is a little hard for us to feel the thrill of angiographers when they first heard about the Seldinger technique [1]. Present-day radiologists cannot even guess how angiography could have been done without it. We are so used to this method that we have begun dropping the eponym, as it has become the “natural” way to in...

In pursuing quantitative histochemical investigations aimed at demonstrating the biochemical architecture of human frontal cortex (l-4), we found it necessary to determine ganglioside sialic acid in submicrogram amounts. Even when adapted to the microscale, spectrophotometric methods lack the sensitivity required for studying nervous tissue samples containing less than 0.3 pg of sialic acid. Si...
