MeSH headings : Biopsy, Needle; Breast / pathology; Breast Neoplasms / diagnostic imaging; Breast Neoplasms / pathology; Carcinoma, Intraductal, Noninfiltrating / diagnostic imaging; Carcinoma, Intraductal, Noninfiltrating / pathology; Carcinoma, Lobular / diagnostic imaging; Carcinoma, Lobular / pathology; Female; Fibrocystic Breast Disease / diagnostic imaging; Fibrocystic Breast Disease / pathology; Humans; Image Processing, Computer-Assisted / instrumentation; Mammography / instrumentation; Radiographic Image Enhancement / instrumentation; Synchrotrons; X-Ray Diffraction / instrumentation
TL;DR: Six of the seven breast cancer specimens examined with diffraction-enhanced imaging at 18 keV with a silicon crystal with use of the silicon 333 reflection in Bragg mode showed enhanced visibility of surface spiculation that correlated with histopathologic information, including extension of tumor into surrounding tissue.

1986 journal article

THE NUCLEOTIDE-SEQUENCE OF THE CODING REGION OF TOBACCO ETCH VIRUS GENOMIC RNA - EVIDENCE FOR THE SYNTHESIS OF A SINGLE POLYPROTEIN

VIROLOGY, 154(1), 9–20.

By: R. Allison n, R. Johnston n & W. Dougherty  n

TL;DR: The complete nucleotide sequence of the tobacco etch virus (TEV) RNA genome has been determined excepting only the nucleotide(s) present at the extreme 5' terminus, and a function for the large nuclear inclusion protein is suggested by a comparison of the deduced amino acid sequence with a protein data bank.
