The third 2006 issue of volume 19 of Magnesium Research once again
illustrates the multidisciplinary nature of the journal.André MAZUR
is becoming the new Editor-in-Chief of Magnesium Research. I am
very grateful to him to have accepted this heavy duty. I am sure he
is highly capable of maintaining the standards I tried to keep and
that he is going to open new vistas and to widen the readership of
Magnesium Research.This third 2006 issue of Magnesium Research
brings together basic and clinical original papers on an
international basis.1. One original experimental paper is
presented.A.J. Billyard et al. (Provo, UT, USA) showed that a
moderate magnesium deficiency in young male rats resulted in a
significantly decreased plasma melatonin levels in comparison to
the magnesium adequate animals.2. Next come two original clinical
papers.S. Daini et al. (Roma, Italy) showed that serum
Mg2+ levels are significantly higher in patients with
heroin dependence and personality disorders as compared with
patients with depression comorbidity and without comorbidity.A.
Dunicz-Sokolowska et al. (Warsaw, Poland) defined referential
values of five bioelements (Ca, Mg, Zn, Cu, Fe) and of two toxic
metals (Pb, Cd) in the hair of Polish young persons aged 10-20
years.3. Next come three review papers.F.H. Nielsen et al.
(Grand-Forks, ND, USA) updated the relationship between magnesium
and exercise. Exercise induces a redistribution of magnesium in the
body in order to accomodate metabolic needs: for example strenuous
exercise increases urinary and sweat magnesium losses. Marginal
magnesium deficiency impairs performance. Increased dietary
magnesium intake could be beneficial to physically active
individuals with deficient magnesium status.T. Günther (Berlin,
Germany) analyzed the mechanisms of the magnesium efflux from
erythrocytes. It can be performed by:– the
Na+-specific Na+/Mg2+
antiport,– Mg exchange via the unspecific choline
exchanger,– Mg efflux accompanied by efflux of intra
cellular Cl- for charge compensation.It can be
altered in various pathologic considerations.J.M. Billiard (Paris,
France) reviewed forty years of research dedicated to brain ageing:
in particular cellular mechanisms involved in memory formation such
as calcium-dependent post-burst after polarisation or long lasting
synaptic plasticity which are significantly affected with advancing
age in parallel to the impairment of cognitive performances. A
magnesium deficit is a relevant factor for ageing-associated
susceptibility to hippocampus decline.4. The Calendar of Magnesium
Meetings and Directions to Contributors followed by the Forthcoming
Contents, complete this third 2006 issue of our quarterly
international journal Magnesium Research.
