To the Editor: Hemochromatosis is an autosomal recessive disorder of iron metabolism affecting 0.2%– 0.5% of white populations. Approximately 90% of affected individuals are homozygous for the C282Y mutation, but the H63D and S65C mutations are also of interest. Various molecular diagnostic methods for detection of these mutations have been described, including a multiplex PCR from Stott et al....

background: sediments in marine environment have a large capacity in binding with heavy metals; therefore, they are potential pollutants of water resources. the anzali wetland, located in the southern region of the caspian sea, iran, has been consistently threatened by heavy metal pollutants because of urban, agricultural and industrial wastewater inflow. the purpose of this study is to investi...

We report about testing a new mobile and sustainable water sample digestion method in a preliminary field trial in Ethiopia. In order to determine heavy metals at the ultra-trace level by stripping voltammetric techniques in water samples from Awash River, we applied our new method of solar UV-assisted sample pretreatment to destroy the relevant interfering dissolved organic matter. The field t...
