For those genes, elevated ROS levels were the trigger of the response rather than iron limitation itself.
Pearson unit-variance scaling has some limitations by itself but is useful in some applications.
In fact, a healthy respect for our limitations is itself a form of competence.
We recognize that the widely used DHI has limitations in itself, having only three response categories for each item to describe the handicapping effect of dizziness, and to capture change.
This kind of limitation can itself be rationalised in instrumental terms.
This limitation manifested itself as patient-time loss from work and other normal activities, unpaid caregiver-time loss from work, and use of health care resources (eg, hospitalization).
To the best of our knowledge, however, there is no clinical evidence confirming that flow limitation by itself is sufficient to prevent the increase in total PEEP when PEEP lower than auto-PEEP is applied.
The views of Whitehead and Hartshorne should also be distinguished from those that affirm that the divine being, by an act of self-limitation, opens itself to influence from the world.
