subject: New Tech Holds Tissue [print this page] Motion can present major challenges in photography in general, not to mention with medical imaging techniques such as MRIs. But a new method using simple suction appears to stabilize living lung tissue without disrupting normal organ function long enough to image the live interactions of living cells, including immune response Acer aspire 5520 battery
to injury.
With more than 20 articles about microscopy under their belts, researchers at the University of California at San Francisco publish their latest findings in this month's issue of Nature."The nature of disease is complex, so if scientists can observe in real-time what's happening in tumors or immune responses as they occur, we can find new ways to intervene," says senior author Max Krummel, associate professor of pathology whose lab developed the new technique.Using microscopes custom-built in their Acer extensa 5220 battery own lab, the researchers turned to their own light-based hi-res imaging technique--using infrared-pulsed lasers--to penetrate deep into tissue layers and observe immune cells in lymph nodes as small as a micron in diameter.This time, in an attempt to see living lung tissue in mice, they built a device that applied a "gentle" amount of suction to the surface of the region they wanted to view. Their super-fast imaging took 30 photos a second, giving them a view of cellular behavior that had previously been too blurry to be useful."As a result of achieving video-rate imaging of events within the lung, we've shown how the immune system behaves during normal function and how tissues are affected in acute lung injury," says Mark R. Looney, coauthor of the paper and assistant professor in medicine. "For other disease processes in other Apple a1185 battery organs, we hope to define how collections of cells participate and how they're organized."
