Just as importantly, Witmer says, the finds "push the evolution of definitive feathers further back in time".
If the colposcopy results proved unsatisfactory for a definitive diagnosis, further exploration of the endocervix was systematically carried out.
Prior to a definitive trial further work on composite outcomes is required to address whether the effect is maintained across different individual endpoints within the composite outcome.
These conclusions, however, are not to be considered definitive without further investigation, especially with the gaps in clear results detailed throughout the review.
Also, to reach a more definitive conclusion, further gene-gene interaction and gene-environment interaction studies, which based on large sample size, are still needed in different population.
Given that the limited replicate number of slaughtered animals in the present study may be not enough to generate a definitive conclusion, further investigation with more number of samples is required to determine the appropriate fish oil supplementation level, duration, and the precise mechanisms by which long chain (n-3) PUFA affect piglets' immunity and growth.
First, we retrieved only 5 patients with the C/C genotype for the EZH2 rSNP57441 SNP: therefore, our findings cannot be considered definitive and further analyses should be conducted in larger patient cohorts to confirm the association between EZH2 SNP variants and protein expression.
Disabled differentiation in hematopoietic stem and/or progenitor cells may underlie both the apoptotic response and maturation defects which occur in both primitive and definitive hematopoiesis, although further studies will be required to definitively elucidate this relationship.
We don't yet have definitive information, and further comment would be premature".
Despite of significant increase of its photon-electric conversion efficiency, a definitive direction for further increment remains ambiguous.
