We adapted the pyrogallol red-molybdate method for total urinary protein to the Cobas Bio centrifugal analyzer. The method is simple, rapid, sensitive, and inexpensive. Addition of 25 mg of sodium dodecyl sulfate per liter to the reagent modifies protein reactivities so that the chromogenicity of human gamma globulins is the same as that of albumin. Results by this method and a comparison metho...

The reaction of the hydroxy radical with thymidine and poly-hydroxy benzenes; i.e., catechol, resorcinol, hydroquinone, and pyrogallol, was studied by ESR spin trapping combined with the UV-A photolysis of hydrogen peroxide. The obtained relative reaction rates reasonably agreed with those previously obtained by pulse radiolysis. Electron distribution in the HOMO obtained by DFT calculations al...

Giant nanocapsules: the solution-phase structures of PgC1Ho and PgC3Ho have been investigated using in situ neutron scattering measurements. The SANS results show the presence of spherical nanoassemblies of radius 18.2 Å, which are larger than the previously reported metal-seamed PgC3 hexamers (radius = 10 Å). The spherical architectures conform to a truncated cubeoctahedron geometry, indicatin...

quinone, pyrogallol, 1,2,4-benzenetriol, and polyphenots such as catechins yielded a significant amount of H202. We also examined the effects of a metal chelator, pH, and Oi on the H202-generating property, and the ge"eration of H202 by the polyphe"ol-rich beyerages, green tea, black tea, and coffee, was determined. The features of the H202-generating property of green tea, black tea, and coffe...
