On the back cover we showcase research into mammalian metabolism of organic selenium compounds by Naoki Furuta in the Department of Applied Chemistry at Chuo University, Tokyo, Japan and colleagues in the Department of Epidemiology and Environmental Health, Department of Internal Medicine, Juntendo University School of Medicine, Tokyo, Japan.

Organic selenium compounds in plants and yeasts are effective chemoprotectants in mammalian cancer. In their research they identified selenomethionine pathways by measuring endogenous and exogenous ⁸²Se levels and quantified selenium compounds and selenoproteins in mice liver, kidneys, plasma and urine.

Metallomics Issue 3 is now available online!

We have a new colourful cover for you to discover all about and an interesting Tutorial Review for you to enjoy. There is also a new HOT article on release of zinc from the olfactory bulb with potential influence on the olfactory process. Take a look at Issue 3 NOW!

Our outside front cover showcases work from Jürgen Gailer and colleagues from the University of Calgary, Canada. The researchers investigated the effect of N-acetyl-L-cysteine (NAC) on the metabolism of cis-platin in human plasma and discovered that  NAC does not ameliorate cis-platin toxicity as well as sodium thiosulfate. To do this, they employed size exclusion chromatography coupled on-line to an inductively coupled plasma atomic emission
spectrometer and visualized NAC effects on the metabolism of CP in human plasma obtained from healthy volunteers.

Effect of MPTP on metal concentration

Our inside front cover features an interesting review written by Dominc James Hare and colleagues from the University of Technology, Sydney. The authors examine the unbalanced metal concentration observed during Parkinson’s disease. In addition, they analyse how cellular metabolism is altered following release of MPTP, a potent toxin that selectively destroys dopaminergic neurons in the substantia nigra. The use of MPTP as a model for Parkinson’s disease is also discussed.

The end of the year is just the right time for us to enjoy the Issue 1 of Metallomics!

Artistic design by Heidi Cartwright from an original photograph of the human choroid plexus by Katherine Davies

We have four beautiful covers featuring outstanding research coming from all over the world. Our original outside front cover shows the work of Kay Double from Australia, who studied copper regulation in the human brain. Copper and copper transporters were localised in the brain by using inductively coupled plasma-mass spectrometry. This work provides new insights into the mechanisms by which copper levels are altered in the brain leading to neurological diseases.

Images of dividing cells

This bright and colorful inside front cover gives us a snapshot of a study from the Georgia Institute of Technology, USA. Christoph Fahrni and co-workers examined the distribution of trace metals such as metal, zinc and iron in mouse fibroblast cells during cell division. Using X-ray fluorescence microscopy, they suggest the mechanisms of inheritance of these metals.
