The phrase "a fold increase of" is not correct in standard English; it should be "a fold increase" or "a fold change of." You can use it when discussing the multiplicative increase of a quantity, often in scientific or statistical contexts.
Example: "The treatment resulted in a fold increase in cell growth compared to the control group."
Alternatives: "a multiplicative increase of" or "a factor increase of."
The data are presented as a fold increase of normalized mRNA copies in liver of fish fed with different experimental diets to normalized mRNA copies in the liver of fish fed with control diet.
The data are presented as a fold increase of normalized mRNA copies in tissues of fish fed with different experimental diets to normalized mRNA copies in the tissues of fish fed with control diet.
Motif-X also computes a fold increase of the kinase motif in the sample by determining the total number of motifs found in the entire rat database.
Relative luciferase activity was significantly increased for co-transfection with S33Y-β-catenin, both for N2PR −2327/−99 as well as N2PR −110 with a fold increase of 5.2 for N2PR −2327/−99 (p = 0.007) and 1.8 for N2PR −110 (p<0.0001) compared to the pcDNA6 co-transfection (5A, B and Supplemental Information S1).
A fold increase of 1.57 was considered as positive.
Cytokine-induced phosphorylation was measured as a fold increase of MFI over the unstimulated sample.
The caspase activities in OMV-treated cells were expressed as a fold-increase of their activities in untreated cells.
The caspase activity in OMV-treated cells was expressed as a fold-increase of that in untreated control cells (set up as 1).
This analysis revealed that the most significant differentiation (most negative Pearson correlation) across all treatment groups, was the sickle versus healthy RBC phenotype, with 201 phosphopeptides being up-regulated in SS vs AA RBCs at a fold-increase of >1.75.
b n.d., not determined a The reported values are percentages of isolates that are predicted to be sensitive to the inhibitor (S category in Table 1), but show a fold-increase of the IC50 for the inhibitor, which is above the cut-off values given in Table 2. Numbers in parenthesis indicate the total number of isolates predicted to be susceptible to the drug in the analyzed data set.
a Drug susceptible isolates were defined as those that in comparison with the wild-type reference clone showed a fold-increase of the IC50 value for each drug, which was below 1.8-fold for AZT, 2.6-fold for ddC, 2-fold for ddI and d4T, 9-fold for 3TC, 4.5-fold for ABC, 6-fold for NVP, DLV and EFV, 1.7-fold for SQV and LPV, 2.5-fold for RTV and IDV, 3.6-fold for NFV and 2-fold for APV.
