Example: "In order to improve our understanding of the issue, we require a more precise delineation of the factors involved."
Alternatives: "a clearer definition" or "a more detailed description".
The mean hypothalamic SERT binding ratio of the present study appeared to be lower than previously reported in the diencephalon [23], possibly related to a more precise delineation of the target area in the present study and to age differences.
Such studies would also provide a more precise delineation of the steric impediments to efficient catalysis.
Variability observed in chromosomal context should enable a more precise delineation of the ASGR.
Accounting for these issues should allow for a more precise delineation of spatial risk patterns and for improved targeting of limited prevention resources earlier in the transmission season.
This combination allows for a more precise delineation of the planning target volume (PTV) and the most accurate irradiation delivery possible.
However, a more precise delineation of the role of autophagy in arthritis will require the silencing of specific Atg genes or the use of animals with selective deficiencies in specific Atg genes.
On the one hand this is mediated by new technical developments, such as chromosomal microarrays, which allow a much more precise delineation of minute sub-microscopic chromosomal aberrancies than the classical G-band karyotype.
According to Glasser and his colleagues at six other research centers, combining anatomical data with functional data from fMRI brain scans has allowed for more precise delineation between brain areas.
With the advancement of computing and medical imaging technologies, digital brain atlases constructed for different imaging modalities are increasingly more common and provide more precise delineation of brain structures and allow automatic processing of large datasets with minimal human intervention.
Given recent advancements in MS technology, it is now possible to use the top-down MS approach to analyze intact histone proteins, thereby allowing for more precise delineation and quantification of the complex modified forms in which the histones exist [25].
With respect to the spinal cord, which is more sensitive to the radiation injury, more precise delineation was needed.
