Single-longitudinal-mode linear-cavity fiber laser using multiple subring-cavities
A single-longitudinal-mode selection is realized in a linear-cavity fiber laser construction using a loop-back optical circulator and a partial reflectance fiber Bragg grating as the cavity ends. At 1551 nm wa...

Spinal 5-HT pathways and the antinociception induced by intramedullary clonidine in rats
The possible involvement of spinal 5-hydroxytryptamine (5-HT) pathways in antinociception induced by microinjection of clonidine into the ventrolateral surface of the medulla oblongata was investigated in rats...

Intraventricular morphine produces pain relief, hypothermia, hyperglycaemia and increased prolactin and growth hormone levels in patients with cancer pain
The effects of analgesic, thermoregulatory and endocrine functions of administering morphine sulphate (0.3mg) into the lateral cerebral ventricle via an Ommaya catheter were assessed in eight patients with can...
