OBJECTIVE The aim of this study was to determine the effect of combined calcium and iron versus single iron supplementation on iron status in Bolivian schoolchildren. METHODS Children ages 6 to 10 y old (N = 195), were randomly assigned to receive either 700 mg Ca (as calcium carbonate) plus 30 mg Fe (as ferrous sulfate) (Ca + Fe group) or 30 mg Fe (as ferrous sulfate) (Fe group). The doses w...

in this study, we have examined the antioxidant activity and total phenolic content of different extracts (including water, methanol, water : methanol and acetone) of nerium oleander l. grown in the north of iran by employing various in-vitro assay, i.e. dpph free radical scavenging, reducing power and total antioxidant capacity through the mo (vi) reduction. the extracts showed different level...

and CN2 have been shown to bind to the catalytic iron site of SOR, and cyanide acts as an inhibitor. To understand how these exogenous ligands alter the physical and reactivity properties of the SOR iron site, acetate-, azide-, and cyanide-ligated synthetic models of SOR have been prepared. The x-ray crystal structures of azideligated [Fe(SN4(tren))(N3)] (3), dimeric cyanide-bridged ([Fe(SN4(tr...

Background: Determining the stability of a callus distraction is today largely based on measurement of bone density and qualitative evaluation of bone structure on plain radiographs. In the present study, we demonstrate how computed tomography (CT) and finite element (FE) models can be used together in a simple and effective manner to evaluate the healing of a leg lengthening. Method of Approac...

The study was aimed to evaluate antioxidant activity of methanolic and aqueous extracts of Bergenia ciliata (Haw.) Sternb. rhizome. Total phenolic content was determined in both extracts. Free radical (DPPH ● and ● OH) scavenging potential of the extracts revealed that both extracts to be active radical scavengers. Reducing (Fe-Fe) power and lipid peroxidation inhibition efficiency (TBARS assay...

BACKGROUND Bitter cumin (Centratherum anthelminticum (L.) Kuntze), is a medicinally important plant. Earlier, we have reported phenolic compounds, antioxidant, and anti-hyperglycemic, antimicrobial activity of bitter cumin. In this study we have further characterized the antioxidative activity of bitter cumin extracts in various in vitro models. METHODS Bitter cumin seeds were extracted with ...

Although microbial activity and associated iron (oxy)hydroxides are known in general to affect the environmental dynamics of 4-hydroxy-3-nitrobenzenearsonic acid (roxarsone), the mechanistic understanding of the underlying biophysico-chemical processes remains unclear due to limited experimental information. We studied how Shewanella oneidensis MR-1 -a widely distributed metal-reducing bacteriu...

conclusions according to the results, it can be concluded that the titanium catalyst doped with iron (fe+3-tio2) processes is an appropriate method for reducing atrazine in polluted water resources. results the results demonstrated that the atrazine removal rate increased by decreasing the initial atrazine concentration and the maximum rate of atrazine removal (41.72%) was at ph = 11, atrazine ...
