It has been hypothesized that nitrate (NO(3)(-)) nutrition might induce iron (Fe) deficiency chlorosis by inactivation of Fe in the leaf apoplast (H.U. Kosegarten, B. Hoffmann, K. Mengel [1999] Plant Physiol 121: 1069-1079). To test this hypothesis, sunflower (Helianthus annuus L. cv Farnkasol) plants were grown in nutrient solutions supplied with various nitrogen (N) forms (NO(3)(-), NH(4)(+) ...

OBJECTIVE To assess the association of breakfast intake with Mediterranean diet adherence, physical activity levels, obesity, selected cardiovascular risk markers and Fe status. DESIGN Cross-sectional study. BMI, body fat percentage and waist circumference were assessed. Physical activity was assessed using a pedometer and diet quality was evaluated by applying the KIDMED index. Blood tests t...

in order to evaluate the effect of priming on germination of black cumin under different levels of salinity, a factorial experiment on base of completely randomized design was conducted with three replications. the main factors consisted of five levels of priming (osmopraiming with kno3 (1 and 3%), salicylic acid (sa) (0.2 and 0.5 mm) and a hydropriming)) and four salinity levels (zero, 75, 125...

Abstract Purpose Stabilization of C1-2 using a Harms–Goel construct with 3.5 mm titanium (Ti) rods has been established as standard reference (SOR). A reduction in craniocervical deformities can indicate increased stiffness at C1-2. result joint gapping. Therefore, the authors sought to study biomechanical consequences gapping on different instrumentations, including novel 6-screw/3-rod (6S3R) ...

A new acidophilic iron-oxidizing strain (C25) belonging to the novel genus Acidithrix was isolated from pelagic iron-rich aggregates ('iron snow') collected below the redoxcline of an acidic lignite mine lake. Strain C25 catalysed the oxidation of ferrous iron [Fe(II)] under oxic conditions at 25 °C at a rate of 3.8 mM Fe(II) day(-1) in synthetic medium and 3.0 mM Fe(II) day(-1) in sterilized l...

Molecular oscillations of ligand motions at the active site of carbonmonoxy myoglobin have been calculated in a protein environment using the combined QM/MM approach. In these calculations, the active site was calculated at a quantum mechanical (QM) level of theory using the B3LYP/6-31 + G* method, while the remaining protein was calculated at the molecular mechanical (MM) level utilizing the A...

in order to evaluate the effects of foliar micronutrients on quantitative and qualitative yield of safflower (carthamus tinctorius l.), a field experiment was carried out at research farm of agricultural faculty, zabol university during growing season of 2005-2006. the experiment performed based on rcbd with 3 replications and 7 treatments including: fe, zn, b, pair combination of them and cont...

In this study, aged (iron oxide coated) Fe(0) was applied to the degradation of trichloroethylene (TCE) in seawater. It was found that while the aged Fe(0) was inactive with regard to TCE degradation in Milli-Q water, more than 95% of the TCE present was degraded in real and synthetic seawater solutions after exposure to aged Fe(0) for 21 days. Results with individual salts from the synthetic s...
