Of those tested, 23 were determined to be infected and 94 were determined to be uninfected. When using the highest level of infection as the threshold for a positive test, the test was 86.4 percent sensitive for infection and 95.8 percent specific for esterase, and when using smallest level of detected infection as threshold, the test was found to be 59.9 percent sensitive and 98.8 percent specific, showing that testing for leukocyte esterase in the synovial fluid is a valuable addition to the diagnostic armamentarium for PJI. LE strips also aid in rapid testing. “While this is our first test of LE strips for use in diagnosing PJI, our findings show the test to be accurate for detecting infection in the synovial fluid. This is encouraging as we continue in our research to better understand, detect and treat PJI in our patients,” said Parvizi.Additional authors on the study include: Elie Ghanem, MD and Bahar Adeli, BA, both with the Rothman Institute at Jefferson.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
