There is a worldwide epidemic of obesity, which is associated with a number of pathologies including dyslipidemia, glucose intolerance, insulin resistance and diabetes mellitus, all of which are risk factors for cardiovascular disease and mortality. Diabetes is characterized by chronic hyperglycemia with disturbances of carbohydrate, fat and protein metabolism resulting from defects in insulin ...

A food web bioaccumulation model was used to compare transport and fate of polychorinated biphenyls (PCB) congeners in three food webs in the Laurentian Great Lakes of North America. The model was used to quantify the contribution of sediment-derived and freely dissolved PCBs to the body burden of aquatic biota. In eastern Lake Erie (OH, USA), almost 100% of the chemical body burden of biota or...

This paper reports on the levels of organochlorine pesticide residues in edible biota from the coastal area of Dar es Salaam city, Tanzania. Samples were collected from the Msimbazi and Kizinga rivers and from the coastal marine environment receiving waters from these rivers. The samples were analysed for various organochlorine pesticide residues using GC-ECD and the results confirmed with GC-M...

Since the early times, radioprotection has been focused on the human being. Currently this approach has changed, being now also necessary to take care of the protection of the environment from unwanted effects of ionizing radiation. To this end, several institutions (UNSCEAR, ICRP, IAEA, DOE, ACRP) and consortia of institutions (FASSET, ERICA) have established procedures in order to protect the...

The net effects of soil biota on exotic invaders can be variable, in part, because net effects are produced by many interacting mutualists and antagonists. Here we compared mutualistic and antagonistic biota in soils collected in the native, expanded, and invasive range of the black locust tree, Robinia pseudoacacia. Robinia formed nodules in all soils with a broad phylogenetic range of N-fixin...

The main interest of this study is to assess whether uranium deposits located in the San Marcos outcrops (NW of Chihuahua City, Mexico) could be considered as a source of U-isotopes in its surrounding environment. Uranium activity concentrations were determined in biota, ground, and surface water by either alpha or liquid scintillation spectrometries. Major ions were analyzed by ICP-OES in surf...

In this article Gretchen E. Minton describes her adaptation of William Shakespeare and Thomas Middleton’s 1606 play Timon Athens. This adaptation, called Anaconda , focuses on the environmental legacy Butte, Montana, a mining city that grew quickly, flourished, fell into recession, then found itself labelled largest Superfund clean-up site in United States. envisions as wealthy mogul whose loss...
