Bismuth in 5 ml of blood or 10 ml of urine is determined by dilution to 100 ml with 0.25 M HCl, separation by anion exchange chromatography (Amberlite IRA-400 (Cl)), and measurement by differential pulse anodic stripping voltammetry in the presence of 0.1 M KCl.doi:10.1080/00032718108081452Kauffmann, J-MPatriarche, G....
Securing the evidence in various investigative situations is often associated with trace analysis, including fingerprints or blood groups. However, when classic and conventional methods fail, trace elements, such as copper, zinc, fluorine, and many others found in exceedingly insignificant amounts in...
Clinical studies have also shown that Se supplementation can increase intracellular concentrations of the antioxidant glutathione (GSH) and the activity of its synthesis-limiting enzyme γ-glutathione cysteine ligase. It can reduce tissue and blood concentrations of oxidants and slow human aging (Richie ...
In the original publication, an error occurred in both the abstract and the discussion section. Specifically, after adjustment in the logistic regression model, the concentration of Pb was not statistically significant (p = 0.515). While the result section is accurate, the abstract and discussi...
Metal homeostasis is critical for the proper functioning of the brain5. The brain is a target organ for toxic environmental pollutants6. The balance of metals within the brain is regulated through the blood-brain barrier (BBB) and blood-cerebrospinal fluid (CSF) barrier. In physiological condition...

Males have a pouch-like organ on their wing membranes which they fill with an odoriferous substance made out of distinct secretions including saliva and urine30. Male S. bilineata spend up to one hour per day refilling and cleaning their wing sac liquid32, which is then used to attract ...

mice were treated orally with increasing doses of APAP (40, 80, 150, and 250 mg/kg) in a total volume of 0.8 ml warm saline. The control group received saline. After 4 h of respective treatment, the mice were anesthetized, and blood and liver samples were collected for further analysis...
However, although these matrices are relatively easy to obtain, their TE concentrations might not always correlate with total body storage in humans (Bogden and Klevay, 2000). Thus, urine and blood TE concentrations are considered indicators of recent intake (Navarro-Alarcon and Cabrera-Vique, ...
