Further research is also needed on hearing loss for workers with long term duration of exposure as well as intermittent and irregular exposure to high levels of noise to determine optimal hearing conservation strategies for workers in these environments.
The time points of all participant-related actions to be taken during the study period are presented in table 1. Retaining participants in a clinical trial of long-term duration represents a substantial difficulty for research teams.
In SCI, local intraspinal injection of PLGA-Nrg-1 microparticles maintained significantly higher tissue levels of Nrg-1 for a long-term duration compared to Nrg-1 delivered intrathecally by osmotic pumps.
That's exactly what we must do on long-term duration space missions.
Migration is differentiated by short- and long-term duration.
These adverse effects may be of short-term or long-term duration, or require interventions.
Based on two relevant load cases, out-of-plane bending and in-plane shear, the connection performance is investigated both for short and long-term durations.
Some coordination will need to continue for the long term, not just for the duration of this crisis, Allen argues, pointing to market volatility sparked by rapid changes in exchange rates and vast differences in interest rates from country to country.
"We will go long term for more".
Our trial focussed on those patients with long term symptoms at recruitment (average 13 years duration) for whom usual GP care was of limited benefit; however, exploring the potential impact of referral to acupuncture soon after an initial diagnosis of IBS would be useful.
