The overall results were similar for the risk of parotid gland tumours. In conclusion, our data add to the evidence against there being an increased Fludarabine risk for parotid gland tumours associated with light-to-moderate use of wireless phones and for less than 10 years of use but offers little information on risk related to more prolonged and/or heavy use.

“BACKGROUND: Two-phase partitioning bioreactors (TPPBs) are considered as a new technology for xenobiotic degradation in gaseous

effluents. However, there is still a need for more knowledge on how to design and scale up TPPBs. The partitioning of the two phases remains a misunderstood method of research. In particular, the impact of pollutant (isopropylbenzene), biomass and surfactant extract needs to be better evaluated.

RESULTS: An adapted scale-down

apparatus has been developed in order to quantify the speed of phase partitioning (SPP) into a plug flow section. First, it LY2090314 mw was shown that isopropylbenzene (IPB) does not destabilise the system more significantly. Second, respectively 0.5 g L(-1) and 0.05 g L(-1) of biomass and surfactant extract, separately or in mixture, were sufficient to ensure the stability of the two-phase system. Finally, a 100 m(3) limit of scaling-up was suggested on the basis of the circulation time comparison.

CONCLUSION: The scaling up of an aqueous-silicone oil TPPB was found to be definitely conceivable when the presence of biotic compounds were considered. However, further

considerations are needed to verify our assumptions, in particular by taking into account the velocity field pattern in full-scale bioreactors and reproduce it in laboratory-scale apparatus. (C) 2010 Society of Chemical Industry”
“The main objective of this study was to test Selleck Flavopiridol the hypothesis that genetic variations in DNA repair genes may modify the association between occupational exposure to solvents and the risk of non-Hodgkin’s lymphoma (NHL). A population-based case-control study was conducted on Connecticut women including 518 histologically confirmed incident NHL cases and 597 controls. Unconditional logistic regression models were used to estimate the odds ratios and effect modification from the 30 single nucleotide polymorphisms in 16 DNA repair genes of the association between solvent exposure and the risk of NHL overall and subtypes. Single nucleotide polymorphisms in MGMT (rs12917) and NBS1 (rs1805794) significantly modified the association between exposure to chlorinated solvents and the risk of NHL (P-for interaction = 0.0003 and 0.0048, respectively).
