Whereas its usefulness for out-of-hospital cardiac arrest seems poor, extracorporeal cardiopulmonary resuscitation (e-CPR, i.e. veno-arterial extracorporeal membrane oxygenation (VA-ECMO) under cardiopulmonary resuscitation) could potentially be a life-saving strategy for refractory IHCA, but data are missing.
The results not only explain the usefulness of an out-of-focus retina, Harland says, they also provide an exciting example of how half-centimeter-long animals with brains smaller than those of house flies still manage to gather and act on complex visual information.
I think my real usefulness evolves out of … it's not even compassion, it's more like obsession".
Another set of recommendations deals with the usefulness of carrying out periodic assessments of teachers' training and the actual impact that it has, e.g., by comparing the results achieved by teaching staff that receives training versus the results obtained by those who do not receive training (Klinger, 1973).
When "experts" doubt survivors, hold them responsible for the assault, or refuse to provide assistance, survivors may question both the effectiveness of such services and the usefulness of reaching out for help to anyone at all.

"You give people the opportunity, the usefulness of going out and discovering things offline — but if they want to look back and see what they've done, then they can".
The negative predictive value was 88-89% showing the usefulness of carrying out the HCV-RNA testing at week 12 in the retreatment cases.
Different eluents gave different phosphopeptide spectra, showing the usefulness of carrying out sequential elution with various elution buffers rather than relying on just one (Kyono et al. 2008).
This study was designed to find out the usefulness both of peak myocardial systolic velocity (Sm) and of the myocardial performance index (MPI) of the right ventricle measured by pulsed-wave tissue Doppler imaging (TDI) in assessing right ventricular function.
