Comparing assays 2 and 4, it was observed that a 40% increase in the MgSO 4 concentration in the medium reduced the enzyme activity to 6.58 ± 0.35 U.mL-1, showing the negative effect of a salt concentration increase, which was a significant effect for all enzymes .
Nov 01, 2004· The mineral concentration gradients in the occlusal slices were steeper than those in the cervical slices. The difference in mineral concentration between the inner and outer enamel ranged from 1.5 to 8.7%. CONCLUSION: In view of the large variation in both the means and the gradients of mineral concentration in deciduous molars, the mineral ...
Nov 10, 2017· Partial correlations were used to investigate the association between the concentration of each mineral and each suspected risk factor or other minerals. The percent of squared partial correlations of minerals have been shown in Table S1. The concentration of selenium in nails was different in each place of residence (p = 0.008).
Oct 01, 2014· Iron was the only mineral that exhibited a higher concentration in plants that were treated with deltamethrin (26.07 mg 100 g −1). In general, these authors' results showed that the chemicals that were sprayed on the lettuce did not affect the composition and yield of the lettuce.
