Sentence examples for variation is mediated from inspiring English sources

Experiments were conducted to determine if diurnal variations occur in the cellular and humoral immune responses of sexually mature, male Japanese quail and if this diurnal variation is mediated by the daily rhythm of melatonin.

This mechanism of phenotypic variation is mediated by differential expression of the PfRh proteins and activation of specific ligands.

We further demonstrate that most of this variation is mediated by the activity of multiple families of retrotransposons and DNA transposons.

Further studies are needed to collect prospective data on children and young adults' sociodemographic circumstances, track birth region variation in the body weight among such a cohort, and assess if this variation is mediated by social and biological pathways emerging before midlife.

One limitation of our analysis is that our interrogation of these loci is not comprehensive since we are limited to the CpGs tested by the Illumina beadset; however, so far, we do not see evidence that the effect of disease-associated genetic variation is mediated by alterations in chromatin conformation, as marked by changes in DNA methylation.

It is interesting to note that in all cases the translational phase variation is mediated by poly-G tracts, whereas candidates with poly-C, -A, -T, -GA, -CT, -TC, -AT, and -AG tracts have been reported in other Helicobacter spp. [ 4, 5, 11, 33, 34].

Possibly, genetic or maternally induced variation in strikes is mediated through variation in circulating hormone levels, whereas variation in response distance is mediated through receptor-level phenomena.

As far as we are aware, however, it has not been empirically demonstrated that variation in immune response is mediated by genetic variation in body condition, a key element of the CMIH hypothesis [ 14].
