The interaction of DNA with crystalline silica in buffered aqueous solutions at physiologic pH has been investigated by Fourier-transform infrared spectroscopy (FT-IR). In aqueous buffer, significant changes occur in the spectra of DNA and silica upon coincubation, suggesting that a DNA-silica complex forms as silica interacts with DNA. As compared to the(More)
A method is described for the synthesis of isotopically labeled cortisone from commercially available cortisone acetate through a Delta(4,6)-dieneone. Direct deuteration of the dienone acetate with various catalysts in different solvent systems failed to give an isolable product. Initial hydrolysis of the side-chain ester of the Delta(4,6)-dieneone and(More)
