The phrase "alteration free" is not standard in written English and may cause confusion.
It could be used in contexts where you want to indicate that something is without changes or modifications, but it is better to use more common expressions.
Example: "The document was submitted alteration free, ensuring its original content was preserved."
Alternatives: "without alterations" or "free of changes."
For those concerned about staying on the right side of the law, the Real Estate Board of New York provides blank standard lease forms, sublease forms and alteration agreements free on its Web site.
The sensor displays distinct "on off" changes in color and fluorescence upon the alteration of free Fe3+ levels in solution with a reversible response and little interference with other biological relevant metal ions.
The sensor binds to Fe3+ at 1 1 stoichiometry with high affinity (apparent binding constant 1.27 × 107 M−1) and displays a distinct change in colour and fluorescence upon the alteration of free Fe3+ levels with a reversible response and little interference with other biological relevant metal ions.
The Rh 3S sensor binds Hg2+ in a 1 1 stoichiometry with an apparent binding constant 3.71 × 106 M− 1 (log K = 6.57) and displays a distinct change in color and fluorescence upon the alteration of free Hg2+ levels in solution with a reversible response and little interference with other biological relevant metal ions.
As expected, untreated control fibroblasts did not show any alteration in free cytosolic Ca2+ levels (Additional file 1C).
Also, a similar alteration in free calcium concentration has been described in red blood cells of rats chronically treated with L-NAME [ 10].
We report that skin-specific retroviral-like aspartic protease (SASPase) deficiency in hairless mice resulted in dry skin and a thicker and less hydrated SC with an accumulation of aberrantly processed profilaggrin, a marked decrease of filaggrin, but no alteration in free amino acid composition, compared with control hairless mice.
Possible mechanisms that have been proposed by which statins may specifically benefit the transplant population include the alteration of free drug levels, the modulation of thrombotic processes and endothelial function, and the effect on inflammatory and immune responses--both dependent and independent of inhibition of the HMG-CoA reductase enzyme[ 7, 8, 10, 11].
