Heavy metals including cadmium (Cd) and lead (Pb) are entering agricultural soils from different routes and mainly due to human activities. Accumulated Cd and Pb in the soil would eventually enter the human and animal food chains and pose threat to their health. Therefore, evaluating heavy metal accumulation is necessary to prevent soil and environmental pollutions and should be considered by r...

conclusions these results demonstrated that cse, mainly through inhibition of alr2, could prevent or delay the diabetic complications, like cataract formation, as a result of sorbitol accumulation. results the cse inhibited alr2 activity, with an ic50 of 0.54 mg/ml and it was seven and a half times greater than that of alr1 inhibition, indicating the specificity of cse for alr2, rather than alr...

Even using an authenticated synchronous broadcast model, the task of unforgeably time-stamping digital documents still presents some problems. It is simply not practical to assume that all participants will record and store everyone else's documents so that creation times can be veri ed. This paper presents a time and space e cient method for accumulation of time-stamped documents. Whenever a q...

in this study, cadmium (cd) accumulation was studied in an experimental aquatic exposure. mosquitofish (gambusia affinis) were acutely exposed for 96 h to a high concentration of cd (12 mg/l) and were chronically exposed to a low concentration of cd(0.4 mg/l) for 30 days. cd accumulation profiles differed between the two cd exposures. the cd concentation in g. affinis tissues increased linearly...
