We should consider developing a national physician manpower blueprint that projects how many primary care doctors are needed, and how many specialists and subspecialists are required for efficiently managing the healthcare needs of our country, and only pay for the training slots that conform to those numbers.
This is based on the fact that in wild-type cells, Twi1p has an endoribonuclease (Slicer) activity that cuts one of the two strands (the passenger strand) of loaded scnRNAs, and this activity is required for efficiently removing the passenger strand from Twi1p (Noto et al, 2010).
First, certain co-factors might be required for Btd to efficiently activate its target gene transcription, and a lower abundance of these co-factors in type I neuroblasts hinders the functional output of mis-expressed Btd.
It has been established that promoter methylation can repress gene expression and promoter hypomethylation may be required for genes to express efficiently [ 1, 25].
The quantities of the apoptosis-related proteins expressed in each GBM cell line (Table 3A; Supplementary Material) were used as input for the model system and the time to achieve 80% substrate cleavage, a level previously determined to be required for apoptosis to proceed efficiently, was calculated.
A caveat is that even if virus subtypes H3N2 and H5N1 were to reassort in swine, the spread of the reassortant virus among humans might require further virus adaptation events; for example, mutations might be required for the virus to replicate efficiently in humans or to be transmitted among humans (22 ).
To our knowledge, this is the first description of the morphology of neurons destined for the subplate during cortical plate formation, and our observations suggest that these active changes in preplate/subplate neuron morphology and orientation might be required for the cortical plate neurons to efficiently migrate past subplate neurons to their final destination beneath the marginal zone.
None of the metabolite transporters expected to be required for the C4 system to function efficiently in Alloteropsis had high transcript abundance in the C4 compared with the C3 Alloteropsis, preventing the identification of C4-specific genes for these important steps in the hypothesized pathway.
As >3 nucleotides of single-stranded RNA are required for Xrn1 to efficiently load on an RNA substrate (Jinek et al., 2011), the behavior of the DB1-containing RNA may indicate an alternate secondary structure that precludes the 5′ end of this RNA from being recognized by Xrn1.
We show here that stam and hrs are required for tracheal cells to efficiently colonize the tip of the ASP.
