Studying seemingly simple metathesis reactions between ZnCl(2) and (t)BuMgCl has, surprisingly, revealed a much more complex chemistry involving mixed magnesium-zinc compounds that could be regarded as Mg-Zn hybrids. Thus, the reaction of equimolar amounts of ZnCl(2) and (t)BuMgCl reveals the formation of the unprecedented mixed Mg-Zn complex [(THF)(4)Mg(mu-Cl)(2)Zn((t)Bu)(Cl)] (1), as a result...

Introduction: Zinc is an essential trace element playing a vital role in the maintenance of health. Frusemide, a loop diuretic, is known to deplete sodium, potassium, magnesium and calcium levels. But, very few reports exist on its effect on Zinc levels. Hence, this study was performed on rabbits to investigate the same in detail. Material & Methods: Healthy adult New Zealand White rabbits (n=6...

BACKGROUND The diets of postmenopausal women in Western countries tend to be deficient in minerals, even if the energy value is at the recommended level. The objective of the presented population-based cohort study was to assess the intake of minerals (sodium, potassium, calcium, phosphorus, magnesium, iron, zinc and copper) in the diets of women aged above 55 years and to analyse the relations...

Although the biogenesis of ribosomal subunits occurs predominantly in the nucleus, final remodeling steps take place in the cytosol. One cytosolic step has two components: 1) the removal of the maturation factor Arx1, which transits from the nucleus to the cytosol with the pre-60 S subunit, and 2) its subsequent transport back into the nucleus. Two cytosolic proteins, Rei1 and Jjj1, are require...

This study measured excretion of 11 minerals induced by EDTA chelation therapy in 25 adults (aluminum, cadmium, calcium, chromium, copper, iron, lead, magnesium, manganese, mercury, zinc). We administered 20 EDTA infusions (3 g, with magnesium and ascorbate) 1 to 2 weeks apart and measured 24-hr urinary excretions of minerals before treatment and after treatments 1, 10, and 20. A modest supplem...

The study included collecting 40 blood samples [18 females and 22 males] for patients with stroke, the results were compared control group healthy people that 50 [24 26 males], trace elements [zinc, copper, magnesium, manganese, iron, cobalt chromium] measured two groups. It was noted there a significant decrease in level of zinc, manganese chromium patient both sexes, while increase levels iro...

We determined reference values in umbilical cord plasma and erythrocytes for magnesium, total calcium, phosphorus, copper, and zinc, and then calculated correlations and stepwise-regression equations in 66 white full-term newborn infants (35 boys, 31 girls). Only infants meeting certain optimal criteria and benefiting from excellent maternal conditions and uncomplicated pregnancies were include...
