Plant growth, pigment concentration, biochemical parameters and uptake of heavy metals were determined for Brassica juncea L. in response to cadmium and lead stress. The plant exhibited a decline in growth, chlorophyll content and carotenoids with Cd and Pb but Cd was found to be more detrimental than Pb treatment in B. juncea. The protein content was decreased by Cd (900 μM) to 95% and 44% by ...

A summary of the photometric data obtained by the Hipparcos and Tycho missions is presented. The photometric signals and their reduction to magnitudes are described, as well as the passbands and their evolution. The main mission photometry provided on average 110 observations for each of the 118 000 stars observed during the mission. The accuracies for this epoch photometry range from a few mil...

core decompression (cd) of the femoral head is one of the effective treatments of avascular necrosis (avn), especially in the early stages of the disease. to investigate further the value of cd in treating the avn, this study was performed on patients with symptomatic avn with different etiologies who were treated with cd. this study was carried out on 25 patients (with the total number of 37 f...

this study was carried out as a factorial experiment with 5 levels of cadmium (cd) (o, 25, 50, 75, and 100 mg/kg), 5 levels of salinity (control, 4, 5, 6, and 7 ds/m), and two soil textures (sandy loam and clay loam). the results showed that the amount of cd in root and shoot of sunflower increased as soil salinity and cd concentration increased. the best concentrations for cd phytoremediation ...

effects of ?-cyclodextrin, ?cd, on refolding of lysozyme was investigated at ph 12 employing isothermal titration calorimetry (itc) at 300k in 30mm tris buffer solution. ?cd was employed as an anti-aggregation agent and the heats obtained for lysozyme+?cd interactions are reported and analyzed in terms of the extended solvation model. it was indicated that there are two sets of identical and no...
