Radial glial cells and astrocytes function to support the construction and maintenance, respectively, of the cerebral cortex. However, the mechanisms that determine how radial glial cells are established, maintained, and transformed into astrocytes in the cerebral cortex are not well understood. Here, we show that neuregulin-1 (NRG-1) exerts a critical role in the establishment of radial glial ...

BACKGROUND The radial forearm free flap is a workhorse free flap. The radial artery, which supplies it, is increasingly being used for endovascular access. A complication of this is radial artery occlusion. Although often asymptomatic it can compromise future free tissue transfer. CASE PRESENTATION Two patients who underwent RFFF harvest for head and neck reconstruction are presented; both of...

A review of the literature was performed to survey the history of the radial head prosthesis in traumatology. Radial head resection was the treatment of choice before Speed first reconstructed the radial head with a metal prosthesis. Over the years, the indication for the use of a radial head prosthesis changed from the prevention of heterotopic ossification to the prevention of proximal migrat...
