Is the zebrafish fast myosin light chain mylpfa : H2B-GFP transgene a useful tool for in vivo imaging of myocyte fusion in the vertebrate embryo?
Since we know so little about the molecules regulating vertebrate myocyte fusion, we propose that the mylpfa:H2B-GFP transgene will be a very useful reporter for conducting forward and reverse genetic screens to identify new components regulating vertebrate myocyte fusion.
Concurrent use of oral vasodilators does not appear to mask a significant response to inhaled NO on the pulmonary vasculature. Therefore, routine discontinuation of pulmonary vasodilators is likely unnecessary before vasodilator testing in patients with pulmonary arterial hypertension.
