Patterning of the vertebrate skeleton requires the coordinated activity of Hox genes. In particular, Hox10 proteins are essential to set the transition from thoracic to lumbar vertebrae because of their rib-repressing activity. In snakes, however, the thoracic region extends well into Hox10-expressing areas of the embryo, suggesting that these proteins are unable to block rib formation. Here, w...

A high-sensitivity Mach-Zehnder interferometer (MZI) biochemical sensing platform based on Silicon-in-insulator (SOI) rib waveguide with large cross section is proposed in this paper. Based on the analyses of the evanescent field intensity, the mode polarization and cross section dimensions of the SOI rib waveguide are optimized through finite difference method (FDM) simulation. To realize high...

We report a case of benign fibrous Histiocytoma of the left tenth rib in a 40-year-old man. CT revealed an expanding lesion with calcification. An open biopsy of the lesion was performed and subsequently wide surgical resection of the left 10th rib was performed. Histological diagnosis was consistent with benign fibrous Histiocytoma of the rib.

In years past, a rather voluminous literature has accumulated dealing with certain neurologic and circulatory deficits that occur in the upper extremities. Cervical rib syndrome, scalenus anticus syndrome, Naffziger syndrome, and scalenus neurocirculatory compression syndrome are among the names applied to the variable symptom complex found present in a small percentage of individuals with abno...

BACKGROUND Surgical management of fractured ribs with internal fixation is an increasingly accepted therapy. Concurrently, specific rib fixation prostheses are being developed which should improve results and minimise hardware and rib/splint construct failures. The Synthes titanium intramedullary splint lends itself to difficult to access areas such as posterior rib fractures and fractures unde...

IN the past seven years four cases of cough fracture with eight fractures were found at Killadeas Hospital and the Chest Clinic, Erne Hospital, Enniskillen. No previous record of cough fracture of a rib in Northern Ireland is known to the writer. Yet any patient with a history of cough followed by pleuritic pain may be suffering from one. Other conditions predisposing to fracture may also be pr...
