High-performance liquid chromatographic analysis of 32P-postlabeled DNA-aromatic carcinogen adducts

The technique of 32P postlabeling of DNA-carcinogen adducts is a useful and extremely sensitive method of detecting and quantitating DNA damage by carcinogens. We have adapted the 32P method to analysis by high-pressure liquid chromatography, making the procedure more rapid and convenient than when thin-layer chromatography is used. Following DNA isolation and hydrolysis, nucleotide-carcinogen adducts are enhanced relative to normal nucleotides by solvent extraction and then labeled with high-specific-activity [[gamma]-32P]ATP. The resulting 32P-postlabeled nucleotides are resolved by reverse-phase ion-pair HPLC. After as little as 3 h of exposure to carcinogens, DNA adducts can be demonstrated from 1 [mu]g or less of mouse hepatic DNA. Acetylated and nonacetylated adducts can be resolved from hepatic DNA of mice treated with 2-aminofluorene. Differences in DNA damage as measured by adduct formation were demonstrated between "rapid" and "slow" acetylator mouse strains. Rapid-acetylator C57BL/6J mice had three times the amount of hepatic DNA adducts as slow-acetylator A/J mice 3 h after a 60 mg/kg dose of 2-aminofluorene. 4-Aminobiphenyl and 2-naphthylamine each showed an adduct peak with retention time similar to that of the nonacetylated 2-aminofluorene adduct, while benzidine gave a major adduct that eluted somewhat earlier as would be expected for an acetylated adduct. The alkenylbenzenes, safrole and methyleugenol, also formed DNA adducts detectable by this method. DNA prepared from skin of mice painted with benzo[a]pyrene also contained carcinogen-DNA adducts detectable and resolvable by HPLC analysis following 32P postlabeling. The combination of HPLC with 32P postlabeling appears to be a useful technique for the rapid detection and quantitation of DNA damage caused by several classes of aromatic carcinogens.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/27086/1/0000077.pd

Measurement of νˉμ\bar{\nu}_{\mu} and νμ\nu_{\mu} charged current inclusive cross sections and their ratio with the T2K off-axis near detector

We report a measurement of cross section $\sigma(\nu_{\mu}+{\rm nucleus}\rightarrow\mu^{-}+X)$ and the first measurements of the cross section $\sigma(\bar{\nu}_{\mu}+{\rm nucleus}\rightarrow\mu^{+}+X)$ and their ratio $R(\frac{\sigma(\bar \nu)}{\sigma(\nu)})$ at (anti-)neutrino energies below 1.5 GeV. We determine the single momentum bin cross section measurements, averaged over the T2K $\bar{\nu}/\nu$-flux, for the detector target material (mainly Carbon, Oxygen, Hydrogen and Copper) with phase space restricted laboratory frame kinematics of $\theta_{\mu}$500 MeV/c. The results are $\sigma(\bar{\nu})=\left( 0.900\pm0.029{\rm (stat.)}\pm0.088{\rm (syst.)}\right)\times10^{-39}$ and $\sigma(\nu)=\left( 2.41\ \pm0.022{\rm{(stat.)}}\pm0.231{\rm (syst.)}\ \right)\times10^{-39}$in units of cm$^{2}$/nucleon and$R\left(\frac{\sigma(\bar{\nu})}{\sigma(\nu)}\right)= 0.373\pm0.012{\rm (stat.)}\pm0.015{\rm (syst.)}$.Comment: 18 pages, 8 figure
