Available zinc status of lebanese soils

Assessment of zinc status.

Although the gross skin rash of profound zinc deficiency is well documented in patients with acrodermatitis enteropathica, glucagonoma and severe deprivation, this striking clinical manifestation is rare. Unfortunately, other clinical signs are variable and difficult to assess, and so we seek a quantitative assessment of body Zn stores (Solomons, 1979). There are two different measurements for ...

On the competition for available zinc.

Extended x-ray absorption fine structure (EXAFS) spectroscopy was combined with thermodynamic and kinetic approaches to investigate zinc binding to a zinc finger (C2H2) and a tetrathiolate (C4) peptide. Both peptides represent structural zinc sites of proteins and rapidly bind a single zinc ion with picomolar dissociation constants. In competition with EDTA the transfer of peptide-bound zinc io...

Zinc Fertilization of Rice Grown on Clay Soils in Arkansas

Zinc (Zn) fertilizer is not currently recommended for rice grown on clay or clay loam soils in Arkansas. In 2003, eight field sites were established to evaluate the response of rice grown on clay soils to Zn fertilization. Shortly before or after seeding, granular Zn fertilizer was applied to the soil surface at rates of 0, 5, 10, and 20 lb Zn/acre. Tissue Zn concentration 10 to 14 days after f...

Zinc metabolism and thyroid status.

Urinary zinc excretion was found to be increased in patients with thyrotoxicosis when compared to euthyroid individuals. This increase did not appear to be due to an increase in creatinine clearance and was found to be strongly correlated with an index designed to assess the severity and acuteness of the metabolic response of the body to hyperthyroidism. The potential clinical significance of t...
