Such resistance signified continual deep-rooted discontent with the condition of bondage and, in some places, such as the United States, resulted in ever-more-stringent mechanisms for social control and repression in slaveholding areas.
It is therefore likely that these RNAs were independently recruited into their current repression function at a later time in mammalian evolution during which increasing brain complexity required more stringent translational control mechanisms.
The future versions of QDB might become more stringent and specify a mechanism for explicitly listing all recognizable files.
In embryo-retaining eutherian mammals, the secondary reduction of yolk accumulation and extreme reduction in oocyte size necessitated reintroduction of the egg's polyspermy-preventing mechanisms and/or more stringent control of sperm numbers at the site of fertilization.
Although Stearns dutifully makes some policy proposals — more carefully directed aid with conditions on it; more stringent regulation of "mining cowboys"; a mechanism for holding the worst perpetrators to account — he is wise enough to know how difficult it will be to halt 15 years of violence and pillage.
With the establishment of official curriculum guidelines, more stringent teacher qualification requirements, and enhanced monitoring mechanism, the objective of the Hong Kong ECE reform, however, is to dissuade schools from putting too much emphasis on academic achievement and formal training.
In the present study (Garg et al., 2009), the lower threshold for immune cell entry into the CNS provides a more stringent test of whether there are CNS-intrinsic mechanisms that cannot be replaced by the peripheral immune system.
If so, the full discovery and understanding of biological processes underlying CRC on a genomic scale would be possible only with a more stringent approach, which requires an extensive knowledge of signaling mechanisms in all biological processes considered.
Integration of these pieces of information will allow for a more stringent control over the cell grafts and elucidate the mechanisms of the action of stem cells therapy in cerebral ischemia.
As reported above, there is, however, first a need for cross-validation of the findings in prospective designs and for more stringent tests of the causal direction of the relevant mechanisms.
