Does bone morphogenetic protein 2 signaling negatively modulate lymphatic development in vertebrate embryos?
Our data identify BMP2 as a key negative regulator for the emergence of the lymphatic lineage during vertebrate development.
The outcome of the radial nerve palsy following humeral fractures is associated to the initial trauma. Palsies that are part of a low energy fracture uniformly recover and therefore primary surgical exploration seems unnecessary. In high energy fractures, neurotmesis or severe contusion must be expected. In this case nerve recovery is unfavourable and the patients should be informed of the poor prognosis and the need of tendon transfers.
