Photoluminescence properties of multiple stacked planes of GaN/AlN quantum dots studied by near-field optical microscopy.

We have studied the photoluminescence properties of GaN quantum dots with submicrometre lateral resolution by means of near-field scanning optical microscopy. The instrument operated at room temperature and was implemented for near-ultra-violet spectroscopy in the illumination-mode configuration. The analysed sample consisted of several stacked planes of GaN/AlN quantum dots grown by molecular beam epitaxy on Si(111) substrate. The photoluminescence maps showed islands in the micrometre range emitting at different wavelengths, confirming the atomic force microscopy studies on the morphology of similar uncapped samples.

Intramedullary spinal ependymal cyst: case report.

A cervical intramedullary spinal ependymal cyst in a 39-year-old man is reported. Diagnosis was made through magnetic resonance imaging. Total enucleation was possible. This is the sixth such reported case.

Propofol in the treatment of convulsive status epilepticus: a report of four cases.

Propofol is a new anaesthetic agent commonly used because of its rapid pharmacokinetic. Lately, anecdotal reports suggest its utility in the treatment of convulsive status epilepticus. We describe four cases of convulsive status due to severe encephalopathy of various etiology. They were resistant to diazepam and other drugs and remitted only after treatment with propofol. The infusion, even protracted to 8 days, did not cause any toxic or proconvulsive side-effects. The very short duration of its central depressant action permitted monitoring of the underlying neurological status whenever needed.
