Fig. 1. SSCP analysis of rat and mouse gene-derived PCR amplification products for protein phosphatase 2Cc~ gene. The PCR products were diluted first 10-fold in 0.1% SDS, 10 mM EDTA, and then 1:1 in 95% formamide, 20 mM EDTA, 0.05% bromophenol blue, and 0.05% xylene cyanol. After boiling of the products, electrophoresis was performed in 6% polyacrylamide(More)
The anterior annulus from patients undergoing surgery for low-back pain was compared with the same region removed at autopsy. Collagen, proteoglycan, and water content were measured in different regions across the annulus. Water and proteoglycan contents increased from the outer to the inner annulus, whereas the collagen contents declined. Quantitative(More)
A "halo sign" has been described in patients with Crohn disease, ulcerative colitis, radiation enteritis, ischemic colitis, and pseudomembranous colitis. This sign is characterized by an inner ring of low CT attenuation surrounded by a higher attenuation outer ring. We present a patient with primary intestinal lymphangiectasia in whom CT demonstrated a halo(More)
Better proxies for the information about future returns contained in firm characteristics such as size, book-to-market equity, cash flow-to-price, percent change in employees, and various past return measures are obtained by breaking these explanatory variables into two industry-related components. The components represent (1) the difference between firms’(More)
