This finding is consistent with the findings of a multicentre study [ 19] which reported a widespread difference between countries in the prevalence of pacifier use ranging from 12.5% in Japan to 71% in the Ukraine.
Even though AMP is able to sample only a small part of the genome, it was a good indicator of widespread differences in DNA methylation between WT and 2HA.
Many splicing regulators have tissue-specific expression patterns, resulting in widespread differences in AS patterns across different tissues.
Consistent with a recent study (Coppola and Waggener, 2011), we identified widespread differences in gene expression after activity deprivation in WT mice, with 'olfactory detection' (ORs) identified as the most highly enriched gene ontology category among both up- and down-regulated genes.
More recently, widespread differences in brain structure have been observed between Chinese and Caucasian cohorts [5], a finding particularly important for automated image processing methods which rely on population-specific brain atlases.
[72], [93], [94], [95], [96], [97], widespread differences in Mn2+ accumulation at 26 hr between DAT KO and WT mice are likely to represent of indirect consequences of alterations in dopaminergic signaling induced directly by deletion of DAT.
We found strong effects in the theta band (4 6 Hz) that reflected widespread differences in cortical activity across conditions.
Analysis of fractional anisotropy and diffusivity maps revealed widespread differences in white matter integrity between the groups.
The authors hypothesised that 'deficits in verbal working memory following recovery from SAH are accompanied by widespread differences in hemodynamic correlates of neural activity.
