In contrast, fatigue has been reported in p.C282Y homozygotes with normal SF 13 15 and has been found to be worse in some individuals following normalisation of SF by venesection treatment.
The average Ct values of the housekeeping genes, β-actin and 18srRNA, were used for normalisation of each individual sample.
Also, in our study, changes in all variables were related to the individual baseline supine level (by normalisation), reducing the effects of large variations of measured parameters and difficulties with standardisation of the used techniques (TCD, NIRS and BP).
Gene expression was calculated using the 2-∆∆CT method, whereby the results of each individual group were compared after normalisation to Canis familiaris glyceraldehyde-3-phosphate dehydrogenase (GAPDH) expression.
Probes with less than three beads present were excluded and log2-transformed expression signals were normalised separately per tissue, with quantile normalisation of the replicates of each individual followed by quantile normalisation across all individuals.
The intake of L-Thyroxin by four middle-aged individuals was deemed appropriate for normalisation of metabolic state.
In fact, in our study, 30.3% of 452 individuals with low microalbuminuria demonstrated normalisation.
We downloaded background-corrected gene expression values from the Gene Expression Omnibus (GEO) database (accession number GSE6536), and then carried out quantile normalisation across replicates of a single individual and subsequently median normalisation across all individuals by using the R package beadarray [ 13].
Persson (2005) reports that normalisation can lead some individuals to engage in higher-risk behaviours, including increased UAI.
Hence, observed discrepancies may reflect the inability to precisely model array normalisations by assays on individual mRNA samples in our validation experiments, differences in primer or probe recognition sites or non systematic errors.
