Creating Biomedical Technologies to Improve Health



Science Highlights • April 29, 2011
A new technology based on radiolytic labeling and mass spectrometry yielded the first high-resolution structural model of a potassium channel in open and closed positions. The model will improve scientists’ understanding of ion flow through potassium channels, a crucial component of heart and nerve function.

Pregnant women in rural and underserved areas in the United States and overseas could benefit from access to low-cost ultrasound equipment. A new approach to making transducers developed by researchers at General Electric’s Global Research Center in Niskayuna, New York, has the potential to reduce ultrasound system costs and increase access to prenatal ultrasound.

Early detection can be a matter of life and death for a cancer patient. To make cancer screening accessible to more patients, Rice University scientists and collaborators designed a low-cost portable microendoscope that enables detecting cancerous tissue at the point of care. The device may also be used to direct physicians where to take a diagnostic biopsy, aid in prognosis, and monitor treatment.

Rapid, sensitive screening of biomolecules allows researchers to ask new questions about why diseases begin and how they progress. Investigators at the Massachusetts Institute of Technology have developed a fabrication technique and a screening system that match the accuracy of current molecular screening tests but are faster, less expensive, and easier to use.

Blood passing through a hemodialysis machine has a tendency to clot. University of Pennsylvania researchers discovered that the clotting is connected to an immune reaction to biomaterials used in the machine’s tubing and filters. They devised two strategies to tame the immune reaction and thereby reduce blood clotting.

Millions of people living in low-resource settings go undiagnosed because they do not have access to diagnostics laboratories. Point-of-care diagnostic technologies are turning the table on this trend, bringing preventive screening, disease diagnostics, and disease monitoring tests to the field.

Deep brain stimulation (DBS) has become a popular therapy for patients with movement disorders that no longer respond to medication. The delicate surgery requires pinpoint precision when placing electrodes on brain structures responsible for movement. To assist surgeons and increase the number of successful patient outcomes, Vanderbilt University researchers have developed a robust database and suite of software tools that automate DBS planning, placement, and programming.
