Researchers have developed a new test to measure corrosive free-radical activity in individuals, providing insight into antioxidant effectiveness. The test uses an isoprostane marker, IPF2alpha-I, which can be detected in urine, and has been validated through cross-validation with an older assay.
Researchers at Ohio State University found that two simple tests can detect carpal tunnel syndrome with high accuracy. The square-shaped wrist and abductor pollicis brevis (thenar) weakness tests are recommended as part of the examination for CTS, which is often caused by repetitive motion like typing.
A new liquid crystal assay developed at the University of California, Davis, can detect target molecules in test samples using minimal supplies and no electricity. The assay uses a microscopic landscape of hills and valleys to bend light and create colorful patterns, allowing for quick and easy analysis.
