Because these contrasting evidences, in a recent statement, the FDA expressed an unfavorable opinion to the use of ASA for the primary prevention of heart attack and stroke (http://www.fda.gov/Drugs/ResourcesForYou/Consumers/ucm390574.htm), by underlying the serious risks of bleeding in the stomach and brain associated with the use of ASA without an effective therapeutic usefulness.
While purification of chloroplast generated human IGF-1 to homogeneity remains to be attained, retention of significant biological activity of the ZZ tagged IGF-1 molecule indicates its effective biological usefulness even in an altered state.
The fact that 'control' health conditions (fever and cough) remained unchanged by the intervention also suggests that blinding may have been effective, although the usefulness of this approach to detect the presence of respondents' bias has not been validated.
For effective technology transfer, the usefulness of the framework should be evaluated and shown to the organization.
While some compounds, most notably the Walter Reed (WR) class of radioprotectors, have reported limited effectiveness when given before exposure to low-LET radiation, the human toxicity of these molecules at effective doses limits their usefulness.
In addition, the MAE value by itself seems not to be an effective measure of the usefulness of a predicted log Kt:p value, because the predicted values will be used as descriptors for building models predicting log Vss in the Vss-target dataset, which is a regression problem very different from the problem of building the models reported in Table 1.
Moreover, effective examples of the usefulness of SOS/SDP-based approaches to elucidate the properties of biological systems are provided in [ 33, 34].
This study identified facilitating EHR implementation factors such as perceived usefulness, motivation, effective onsite technical support and management, and barriers such as concerns about privacy and security.
We might expect that ease of use of online learning would improve over time (as technology improves, learners become more adept, and instructors apply features of effective design), whereas perceived usefulness might remain stable or even decline (as improvements in instructional design are offset by fading infatuation with the new technology and rising expectations).
