Correlative changes in metabolism and DNA damage in turbot (Scophthalmus maximus) exposed to benzo[a]pyrene     

Telli-Karakoç F  Ruddock PJ  Bird DJ  Hewer A  Van Schanke A  Phillips DH  Peters LD 《Marine environmental research》2002,54(3-5):511-515

Juvenile turbot (Scophthalmus maximus) were injected intraperitoneally with either corn oil or 5 mg/kg benzo[a]pyrene (BaP) dissolved in corn oil and sampled I and 3 days after injection. After 1 day, no elevation of 7-ethoxyresorufin O-deethylase (EROD) activity was observed, however bile metabolites (BaP-7,8 dihydrodiol representing 70% of the total metabolites) and a single hepatic DNA adduct spot (0.47 adducts/10(8) nucleotides) identified by 32P-postlabelling were formed. No BaP metabolites or DNA adducts were observed in either control or carrier control fish. Fish sampled after 3 days reported 5-fold higher (P < 0.05) levels of EROD activity, a shift in the bile metabolite profile towards BaP phenol formation (1OH and 30H BaP comprising up to 60% of total metabolites detected) and the formation of two adduct spots (0.86 and 0.71 adducts/10(8) nucleotides). These results show that BaP can be metabolised and form hydrophobic DNA adducts in turbot without EROD elevation. Following EROD elevation, a shift in the profile of both BaP metabolites and BaP metabolite-DNA interactions occurs indicative of other oxidative processes.  相似文献   

A coupling of mixed and discontinuous Galerkin finite-element methods for poroelasticity     

Phillip Joseph Phillips  Mary F. Wheeler 《Computational Geosciences》2008,12(4):417-435

In this paper, we formulate a finite-element procedure for approximating the coupled fluid and mechanics in Biot’s consolidation model of poroelasticity. We approximate the flow variables by a mixed finite-element space and the displacement by a family of discontinuous Galerkin methods. Theoretical convergence error estimates are derived and, in particular, are shown to be independent of the constrained specific storage coefficient, c _o . This suggests that our proposed algorithm is a potentially effective way to combat locking, or the nonphysical pressure oscillations, which sometimes arise in numerical algorithms for poroelasticity.  相似文献   

Part II. Evaluation of Ar-Ar quartz ages: Implications for fluid inclusion retentivity and determination of initial Ar/Ar values in Proterozoic samples     

M.A. Kendrick  J.McL. Miller  D. Phillips 《Geochimica et cosmochimica acta》2006,70(10):2562-2576

The argon isotope systematics of vein-quartz samples with two different K-reservoirs have been evaluated in detail. Potassium is hosted by ultra-high-salinity fluid inclusions in quartz samples from the Eloise and Osborne iron-oxide-copper-gold (IOCG) deposits of the Mt Isa Inlier, Australia. In contrast, K is hosted by accidentally trapped mica within lower-salinity fluid inclusions of a sample selected from the Railway Fault, 13 km south of the Mt Isa copper mine, Australia. Imprecise apparent ages have been obtained for all of the samples studied and conclusively demonstrate that quartz fluid inclusions are retentive to Ar and have not leaked over billions of years. IOCG samples that host K in fluid inclusions only, have K/Cl values of <1 and the ages obtained represent the maximum ages for mineralization. In contrast, the Railway Fault samples that include accidentally trapped mica have K/Cl values of ?1. Excess ⁴⁰Ar_E plus Cl hosted by fluid inclusions, and radiogenic ⁴⁰Ar_R plus K, are strongly correlated in these samples and define a plane in 3D ⁴⁰Ar-³⁶Ar-K-Cl space. In this case, the plane yields an ‘excess ⁴⁰Ar_E’ corrected age of ∼1030 Ma that is 100’s of Ma younger than nearby Cu-mineralization at Mt Isa. The age is interpreted to reflect ⁴⁰Ar-loss from the accidentally trapped mica into the surrounding fluid inclusions, and is not related to the samples’ age of formation. The initial ⁴⁰Ar/³⁶Ar value of fluid inclusions is widely used to provide information on fluid origin. For the IOCG samples that host K in fluid inclusions only, the initial ⁴⁰Ar/³⁶Ar values are close to the measured values at every temperature of stepped heating experiments. For samples that include accidentally trapped mica, the correction for post-entrapment radiogenic ⁴⁰Ar_R production is significant. Furthermore, because ³⁹Ar_K present in accidentally trapped mica crystals is released at different temperatures to radiogenic ⁴⁰Ar_R lost to the surrounding fluid inclusions, intra-sample ⁴⁰Ar/³⁶Ar variation cannot be reliably documented. The results demonstrate that noble gas analysis is readily applicable to Proterozoic, or older, samples but that if K-mineral impurities are present within quartz the abundance of K must be determined before calculation of mean ⁴⁰Ar/³⁶Ar values that are representative of the samples’ initial composition.  相似文献
