This communication deals solely with a group of cases, hitherto rather obscure, in which damage to the cervical part of the spinal cord occurs without radiographic evidence of vertebral injury or displacement. Two alternative explanations of such injury have been postulated. The first is that the spinal cord pressure is due to acute massive prolapse of an intervertebral disc : but our limited e...

Introduction. We present a case of intraosseous foreign body penetration due to knife attack and its emergency service management. Case. Seventeen-year-old patient was admitted to the emergency department with a knife cut over the right knee. In the local wound exploration during the extension position of the knee, deep tissue penetration was not observed. Therefore, the patient was discharged ...

INTRODUCTION Aggrecanase cleavage at the (392)Glu-(393)Ala bond in the interglobular domain (IGD) of aggrecan, releasing N-terminal (393)ARGS fragments, is an early key event in arthritis and joint injuries. We determined whether synovial fluid (SF) levels of ARGS-aggrecan distinguish subjects with progressive radiographic knee osteoarthritis (ROA) from those with stable or no ROA. METHODS We...

We present a new method for quantitative nondestructive characterization of objects by x-ray phase-contrast imaging. Spatial distributions of the projected values of the complex refractive index in the sample are reconstructed by processing near-field images collected at a fixed sample-to-detector distance using a polychromatic incident beam and an energy-sensitive area detector, such as a CCD ...

Spectroscopic x-ray imaging based on pixellated semiconductor detectors can be sensitive to charge sharing and K-fluorescence, depending on the sensor material used, its thickness and the pixel pitch employed. As a consequence, spectroscopic resolution is partially lost. In this paper, we study a new detector ASIC, the Medipix3RX, that offers a novel feature called charge summing, which is esta...
