The phrase "again by the addition of" is correct and usable in written English.
It can be used when discussing the process of adding something once more to a previous context or situation.
Example: "The experiment was improved again by the addition of a new variable that had not been considered before."
Alternatives: "once more through the inclusion of" or "again through the incorporation of".
Then, the fluorescence could be recovered again by the addition of parathion-methyl (PM) which could inhibit the activity of trypsin.
Furthermore, DOX delivery into the tumor cells was increased again by the addition of GSH even though the CD44 receptor of tumor cells was blocked and nanoparticle uptake was inhibited, indicating that DOX release was facilitated by GSH addition and subsequent cleavage of the HA outer shell.
This creates a reversible wave-like pattern, in which gene expression is switched on by the addition of TETA, and then off again by the addition of Cu.
The second foaming period occurred on days 108 and 109 when the foam was again suppressed by the addition of 100 L of ANU.
The plate was then washed again, followed by the addition of goat anti-mouse immunoglobulin G (IgG) (diluted in 5% BSA-PBS).
As these reactions all resulted in incomplete conversion to the product, the palladacycle (Sp)- 28 was again activated by the addition of 3.8 equivalents of AgNO3 prior to the addition of the substrate.
Over-expression of RASSF4 also inhibited cell growth (colony formation) in MCF-7 cells and A549 lung cancer cells (but not H1299 lung cancer cells) and the effect again enhanced by the addition of a Ras-CAAX motif to the C-terminus of RASSF4 [176].
As shown in Figure 5, co-treatment with SNAP and exogenous Ucn results in a significant decrease in the level of C-20/A4 apoptosis induced by SNAP treatment alone, protection that is again reversed by the addition of α-helical CRH 9-41).
ML results were again significantly improved by the addition of data; for 10 kb datasets, depth 1 branches were estimated accurately and depth 2 branches were overestimated by < 4%.
Consistent with this, infections in plasma were significantly reduced compared with the whole-blood control (86% reduction, P < 0.05), but again was restored by the addition of soybean trypsin inhibitor (Plasma versus plasma + trypsin inhibitor = 316% increase in survival, P < 0.05).
Further, ethanol significantly increased the accumulation of protein adducts of 4-hydroxynonenal, a product of lipid peroxidation serving as an index of oxidative stress; again this was counteracted by the addition of cocoa extract.
