… carbon, pH, dissolved H2S, Cl and SO4 in the pore water. The potential methylation/demethylation rates where determined in sediment sub-samples after incubation 48 hours at 23 ?C. The lake is highly contaminated with a total Hg concentration varying between 20 and 60 mg kg-1 in …
… pH, H2S(g). In incubation experiments using stable isotope labeling, potential methylation and demethylation rates were determined. In the extracted porewater the following parameters were analyzed; Hgtot, MeHg, DOC, Cl-, SO42-, Fe(II)/Fe(III), S(-II) and aromaticity of organic …
… enhanced production in soils of clear-cut areas. The latter process is called methylation and mediated by sulphate and iron reducing bacteria (SRB and FeRB, respectively). The activites of SRB and FeRB may be limited by the presence of sulphate and iron (III), respectively. In …
the DNA repair connection
… H19 ICR on both alleles can communicate with alleles on other chromosomes. The methylation-sensitive insulator protein CTCF is bound on the maternal H19 ICR and acts as an insulator by blocking the IGF2 promoter to access its enhancers. This is possible by formation of loop …
evaluation of a maternal diet restriction model during gestation
This study was conducted at the University of Bath, UK, from September to December 2014 as part of an ongoing research project aimed at elucidating how the Grb10 gene might act as a mediator of long-term health effects (such as predisposition to obesity, diabetes, coronary heart …
… or removal of methyl groups to genes can inhibit or activate gene-expression. Methylation and demethylation is a normal phenomenon in the body and it is essential for the development and survival of the individual. The risk of developing a tumor disease is increased if the …
