Trace metal contents of cerebral vessels in age-matched and sex-matched subjects from three population groups were estimated. The trace metals included calcium, manganese, zinc, magnesium, copper and iron. The American blacks in Washington, D.C., who are ethnologically related to Nigerian Africans, have different patterns of trace metal contents in their cerebral vessels and the observed levels...

The effects of iron deficiency on the levels of iron, copper, zinc and magnesium in the brain, liver, kidney, heart and lungs of albino rats (Rattus novergicus) was investigated. Forty rats were divided into two groups and the first group was fed a control diet containing 1.09g iron/kg diet while the test group was fed diet containing 9ppm iron/kg diet. Tissue iron level reduced in all the diet...

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...

To clarify whether the urinary excretion of calcium, magnesium, phosphorus, iron, zinc, copper, manganese, selenium and molybdenum can be used as an index of their intake, the association between urinary excretion and intake in free-living individuals was examined. A total of 102 healthy free-living female university dietetics students aged 18 33 years voluntarily participated in this study, of...

Fifty HIV disease/AIDS seronegative subjects aged 23.6 ± 16.5years (female=25: male =25) were recruited as normal control subjects. Thirty HIV disease/AIDS seropositive patients that presented with the symptoms of AIDS especially, aged 19.2 ± 10.7years (female: 15 aged 22.0 ± 12.1 years: males = 15 aged 20.6 ± 11.3years) were used as test subjects. Serum total calcium, magnesium and zinc were a...

Tests have been conducted to determine the effect of liming and magnesium treatment on the content of magnesium, calcium and iron in broad bean plants growing on soil polluted with such heavy metals as cadmium, lead, nickel, copper and zinc. In 2005, an experiment was conducted in the village Zagaje Stradowskie (Œwiêtokrzyskie Province) on degraded Chernozem formed from loess, acid in reaction ...

OBJECTIVES To evaluate dietary zinc and other divalent minerals intake among the population of Jiangsu Province. METHODS 3,867 subjects aged 4-89 years were representatively sampled in two urban and six rural areas of Jiangsu Province. Dietary intake was assessed using 24-hour recalls on three consecutive days. Insufficient zinc intake was calculated based on the Chinese Dietary Reference Int...

Psyllium husk, a highly viscous fiber, has beneficial effects for health, but has been reported to inhibit absorption of calcium. The present study found the effects of fiber viscosity on calcium, magnesium, and zinc absorption with partially degraded psyllium preparations to be one fifth viscosity (LD-HP) and one seventieth viscosity (HD-HP) using normal and ovariectomized rats. Magnesium abso...

The role of trace elements in the pathogenesis of liver cirrhosis and its complications is still not clearly understood. Serum concentrations of zinc, copper, manganese and magnesium were determined in 105 patients with alcoholic liver cirrhosis and 50 healthy subjects by means of plasma sequential spectrophotometer. Serum concentrations of zinc were significantly lower (median 0.82 vs. 11.22 m...

A new type of acceptor-donor(2) dyad system containing two magnesium porphyrin molecules and a fullerene molecule is much more stable than the magnesium porphyrin itself. When it is fabricated into a binary system using imidazole carboxylic acid as a linker to indium tin oxide, the molecule effects efficient photocurrent generation that surpasses the device using the corresponding zinc porphyrin.
