Abstract An easy procedure for the estimation of 3,4-dihydroxyphenylalanine (dopa), 3,4-dihy-droxyphenethylamine (dopamine), and homovanillic acid (HVA), besides 3-methoxy-4-hydroxymandelic acid (VMA), by means of the "two solutions paper electrophoresis" (1) is described. Increased amounts of these phenolic compounds were found by this method in the urine of a patient with neuroblastoma, and the case report is presented.

The study of preferred crystallographic orientation (texture) in ceramics is assuming greater importance as their anisotropic crystal properties are being used to advantage in an increasing number of applications. The quantification of texture by a reliable and rapid method is required. Analysis of backscattered electron Kikuchi patterns (BEKPs) can be used to provide the crystallographic orientation of as many grains as time and resources allow. The technique is relatively slow, particularly for noncubic materials, but the data are more accurate than any comparable technique when a sufficient number of grains are analyzed. Thus, BEKP is well-suited as a verification method for data obtained in faster ways, such as x-ray or neutron diffraction. We have compared texture data obtained using BEKP, x-ray diffraction and neutron diffraction. Alumina specimens displaying differing levels of axisymmetric (0001) texture normal to the specimen surface were investigated.BEKP patterns were obtained from about a hundred grains selected at random in each specimen.
