Higher rates of emotional and behavioural problems among youth in the child welfare system seem well substantiated by a range of studies using questionnaire-type measurements and rating scales [ 11– 13].
The methods are "rigorous and well substantiated," says Susan McCouch, a rice geneticist at Cornell University.
The main findings regarding the hierarchical roles of septins, Bud/Cdc42 signaling and sphingolipid biosynthesis for the formation of the diffusion barrier are well substantiated and represent a significant advance in the field.
This assumption could be very well substantiated, considering that glycerol possesses a dielectric constant ε = 42.5 [5] and could favourably change the dielectric constant of water (ε = 80.1), rendering it a reduced polarity for more efficient polyphenol extraction [6].
Although the manuscript concludes that the early cleavage stage defects in M ybx mutants is caused by an enlarged YSL, the possibility that these defects are simply a cause of an aberrant syncytium due to defects in early cytokinesis is not well substantiated.
A few outward facts of Hardy's life are well substantiated.
In fact, it is not a stretch to believe that Congressman Chaffetz is being well substantiated by Hillary's foes to keep this fraudulent investigation going (he should release his emails to prove otherwise).
Although the role of c-CBL in the negative regulation of RTKs is well substantiated, thereby suggesting that it is a natural tumor suppressor, studies in cancer cells have revealed both tumor suppressor and tumor promoting activities depending on the type of c-CBL mutation and the number of alleles at the c-CBL locus [24].
These findings provide important and novel insights into the mechanism of IKs channel gating as well as a framework for interpreting KCNQ effects that is novel, well substantiated, conceptually simple, and thermodynamically plausible.
It is now well substantiated from large epidemiological studies that diabetes confers a modestly (∼1.5 times) increased risk for upper and lower respiratory tract infections (7, 21– 23) compared with two to three times increased risks for severe urinary tract infections and wound infections (21, 22).
