Laser System

MIT researchers have developed a new type of laser based on Optical Coherence Tomography (OCT) for taking high-resolution, 3D images of the retina. OCT uses light to obtain high-resolution, cross-sectional images of the eye to visualize subtle changes that occur in retinal disease. Conventional OCT imaging typically yields a series of 2D cross-sectional images of the retina, which can be combined to form a 3D image of its volume. The system works by scanning light back and forth across the eye, measuring the echo time delay of reflected light along micrometer-scale lines that, row by row, build up high-resolution images. Commercial OCT systems scan the eye at rates ranging from several hundred to several thousand lines per second. But a typical patient can only keep the eye still for about one second, limiting the amount of 3D data that can be acquired. Using the new laser, the researchers report retinal scans at speeds of up to 236,000 lines per second, a factor of 10 improvement over current OCT technology. Click here for the full story.

Current Attractions

Embedded Technology (ET) magazine features board-level electronics and COTS solutions for design engineers, as well as a variety of product offerings. The May issue of Embedded Technology contains a feature article written by Julien Chouinard, managing director at ICS Triplex ISaGRAF (Montreal, Canada), entitled “Distributed Control Standard Connects Industry Regardless of Bus.” The article notes the proliferation of fieldbus networks (such as PROFIBUS, DeviceNET, and SERCOS, etc.) and highlights the implementation of IEC 61499, which created the structure for a supervisory application layer that connects isolated control systems. See page 2 of the May issue for the full article. To read previously published ET articles, cick here.

"Nonsense Mutation" Therapy

Medical scientists at PTC Therapeutics (S. Plainfield, NJ) have entered into trials an oral drug therapy aimed at treating Duchenne muscular dystrophy and other genetic conditions caused by “nonsense mutations.” Nonsense mutations inactivate gene function and are known to cause anywhere from five to 70% of the individual cases of most inherited diseases, such as cystic fibrosis (10%) and Hurler’s syndrome (70%). The drug, PTC124, is designed to bypass the mutations. “As these preclinical data demonstrate, the broad potential of PTC124 lies in its specificity and unique mechanism of action, which has the potential to address the underlying cause of a broad range of genetic disorders due to nonsense mutations,” said Stuart W. Peltz, PhD, president and CEO of PTC Therapeutics. For more information, click here
