The extent of medieval origin of the poems collected in Francis J. Child's English and Scottish Popular Ballads (1882 98) is debatable.
Although the phenomenon is well-established in mammals, the extent of parent-of-origin effects on genome-wide gene expression is a matter of recent controversy (Babak et al. 2008; DeVeale et al. 2012; Gregg et al. 2010a, 2010b) because only ∼30 imprinted loci have been well-characterized and these are mostly found at a few clusters in the genome.
To the greatest extent possible, countries of origin should provide more-complete and accurate diagnoses/records on medical and mental health issues; these are often lacking, so it is more difficult for adopting families to prepare for and meet their children's needs.
Very high levels of carbonates (∼60%), but also of gypsum, both to large extents of primary origin, indicate the incorporation of material derived from marls and limestone.
Recent examples include investigations of the extent and origin of intra-individual variability in toxicity studies, incorporation of genotypic information to address intra-individual variability, optimal design of experiments, and extension of toxicokinetic modelling to the analysis of biomarker studies.
The best method for timely detection of a covert bioterrorist attack is early communication between the two communities and recognition of the extent and origin of the threat.
The spatial diffusion of P. reddelli through time, reconstructed from the mtDNA and ITS data were in general similar, and differed mainly in the timing and extent of the ancestral origin of P. reddelli.
Analysis was undertaken of the dataset by country, and also at a regional level in regard to types of products, country of origin, extent of nutrition labelling and variety available.
The combined or isolated use of MR and PET / CT demonstrated to be useful in detecting gynaecological pathologies and in most cases it also allowed the identification of the organ of origin, extent and staging of the lesion.
Because of the abrupt break in ancient Middle Eastern records as a result of the invasions, the precise extent and origin of the upheavals remain uncertain.
