Multilayered ordering of the metal nanoparticles in polymer thin films under photoirradiation.

Interference light-induced photogeneration of metal nanoparticle in polymer films was explored. The nanoparticle was obtained from metal complex homogeneously dispersed in the film. Standing waves resulting from light interference were generated by irradiating nearly monochromatic light to the sample placed on a reflective substrate.

Radiological findings for arterial dissection of the anterior cerebral artery.

We treated a patient with anterior cerebral artery (ACA) dissection that caused an ischaemic stroke, and investigated serial changes over time by using three different radiological methods. The conventional angiography findings for ACA dissection corresponded to those of computed tomography (CT) angiography, but not those of magnetic resonance angiography for each phase. We presume that the results were based on the velocity of the blood flow in the pseudolumen of the dissected artery, and we believe that CT angiography is a useful and less invasive diagnostic tool for intracranial arterial dissection.
