Although the toxic effects of cyanotoxins on animals have been examined extensively, little research has focused on their effects on higher plants and macroalgae, and the potential for bioaccumulation in the food web through ...

Two silver-contaminated diets were prepared by exposing juvenile rainbow trout for 8 d to waterborne silver thiosulfate as Ag at either 0.1 ?g/L (low-Ag diet) or 80 mg/L (high-Ag diet). The level of total Ag accumulated ...

Protein-bound 3,4-dihydroxyphenylalanine (PB-DOPA) is a major product of hydroxyl radical attack on tyrosine residues of proteins. Levels of PB-DOPA in cells and tissues have been shown to be greatly elevated in age-related ...

ZnO single crystals, epilayers, and nanostructures often exhibit a variety of narrow emission lines in the spectral range between 3.33 and 3.35 eV which are commonly attributed to deeply bound excitons (Y lines). In this ...

A passive sampler device selective for hydrophilic analytes was constructed from cellulose membrane (40 mu m thickness) pre-stained with ruthenium red for 96-168 h to impede degradation of the cellulose. The sampling device ...

Ant assemblages are focal ecological indicators of progress in mine-site restoration, often showing increasing species richness with restoration age. Certain functional groups also behave in predictable ways in response ...

The decomposition of l-¹³C-D-glucose, 6-¹³C-D-glucose, and 1-¹³C-sodium lactate has been studied in hot (145 ± 3°C) alkaline (3.5 M) sodium hydroxide solution in order to understand the mechanisms of carbon exchange in ...
