objective: considering the various evidences due to effects of trace elements on the outcome of pregnancy, we decided to assess the effect of these elements levels in maternal and cord serum on low birth weight. materials and methods: an analytical cross-sectional study was performed on 344 pregnant women in labour and their neonates in maryam, akbarabadi and vali-e-asr hospitals in tehran, ir...

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...

The nitro group in aromatic nitro compounds containing reducible substituents such as methyl, carboxylic acids and phenols, and halogens are selectively and rapidly reduced at room temperature to the corresponding amines in good yield by employing hydrazine glyoxylate in the presence of zinc powder or magnesium powder. It has been observed that hydrazine glyoxylate is more effective than hydraz...

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...

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...
