We describe a metabolic defect in bile acid synthesis involving a deficiency in 7alpha-hydroxylation due to a mutation in the gene for the microsomal oxysterol 7alpha-hydroxylase enzyme, active in the acidic pathway for bile acid synthesis. The defect, identified in a 10-wk-old boy presenting with severe cholestasis, cirrhosis, and liver synthetic failure,(More)
A fully polarimetric optical camera system has been constructed to obtain polarimetric information simultaneously from four synchronized charge-coupled device imagers at video frame rates of 60 Hz and a resolution of 640 x 480 pixels. The imagers view the same scene along the same optical axis by means of a four-way beam-splitting prism similar to ones used(More)
Autoradiographic measurements of peroxidase labelled tyrosine hydroxylase immunoreactivity in brain sections from rats with unilateral 6-hydroxydopamine lesions were obtained using enhanced chemiluminescence. The autoradiograms required only 5-60 s exposure and displayed a good signal-to-noise ratio. The autoradiograms were quantitated using densitometry(More)
