There is evidence for lymphatic drainage of interstitial fluid from the brain along perivascular spaces in a number of mammalian species. Ultrastructural studies suggest that there are similar drainage pathways in the human cerebral cortex. Perivascular spaces in the basal ganglia, however, differ from those in the cortex in that they dilate to form lacunes(More)
to estimate changes in the radiometric response of both sensors. While the 2009 campaign (VCC 2009) indicated significant initial degradation in the sensors compared to the prelaunch values, the results presented here show that the stability of the sensors has improved with time. The largest changes were seen in the 0.76 μm oxygen A-band for TANSO-FTS and(More)
The effect of a wedge-shaped pillow (Ozzlo pillow) was compared with a standard hospital pillow, used to support the abdomen of a pregnant woman while lying on her side, in preventing or alleviating backache and backache-related insomnia; 92 women at 36 weeks' gestation completed the study. Backache was found to be very common (87%), the onset of pain(More)
