Tea polyphenols—including (2)-epigallocatechin-3-gallate (EGCG), (2)-epigallocatechin (EGC), and (2)-epicatechin (EC)—are believed to be responsible for the beneficial effects of tea. This study was conducted to investigate the absorption, distribution, and elimination of EGCG, EGC, and EC in rats after administration of decaffeinated green tea (DGT). For comparison, pure EGCG was also studied....

For the first time, Diffusive Gradient in Thin-films (DGT) focuses on inorganic iodine species iodate (IO3−) and iodide (I−). A silver-doped Cl resin (AgdCl), which is known to selectively accumulate I−, was used make a binding gel. Laboratory investigations were designed verify suitability of AgdCl-DGT method measure total I− concentration environmental waters. Total recovery obtained using an...

One of the best approaches to date to obtain overall binding constants (Ko) for Al and dissolved organic matter (DOM) from acidic soil solutions is to collect 'free' Al data with diffusive gradients in thin films (DGT) and to infer the Ko values by fitting a continuous distribution model based on Scatchard plots. Although there is clear established literature demonstrating the usefulness of the...

UNLABELLED BACKGROUND The metals bioavailability in soils is commonly assessed by chemical extractions; however a generally accepted method is not yet established. In this study, the effectiveness of Diffusive Gradients in Thin-films (DGT) technique and single extractions in the assessment of metals bioaccumulation in vegetables, and the influence of soil parameters on phytoavailability were...

Regular consumption of green tea may be cardioprotective. In the present study we investigated the health effects of dietary supplementation with green tea catechins and the potential modifying effect of the catechol-O-methyltransferase (COMT) Val/Met genotype. Subjects (sedentary males, aged 40-69 years, with BMI ≥ 28 and ≤ 38 kg/m(2)) were randomly assigned to consume decaffeinated green tea ...

Binding resin beads used in DGT (diffusion gradients in thin films) tend to settle to one side of the resin during casting. This phenomenon might be relevant for metal accumulation when partially labile complexes dominate the metal speciation, especially after recognizing the important role played by complex dissociation in the resin domain. The influence of the inhomogeneity of the binding age...

Innovative non-destructive 2D imaging methods such as zymography and diffusive gradients in thin films (DGT) have been developed recently to assess the distribution of phosphatase activity labile solutes at root-soil interface. We report on first combination these techniques for spatial potential interaction phosphorus (P) associated acid rhizosphere blue lupin (Lupinus angustifolius) two contr...

Gizjeling, imprisonment for civil debt, is one of tax collection instruments. The gizjeling institution in Indonesia was once frozen by the Supreme Court which followed Directorate General Taxes (DGT). In other situation, interest state bad debts banking debtors during economic crisis 2000, issued new regulation implementation. At same time, DGT uses facilities against incompliant taxpayer. Thi...

this work summarized the results of a long term monitoring programme performed downstream on the morava river (czech republic). during this programme the total dissolved concentrations and bioavailable fraction of selected metals (zn, pb, ni, cu) were monitored. for the determination of bioavailable metals species, diffusive gradients in thin films technique (dgt) together with moss bags techni...
