Abstract: The present application relates to use of Prussian blue nanoparticles in the preparation of a medicament for the prevention, delay or treatment of neurodegenerative disease. The present application finds that Prussian blue nanoparticles have significant effects in the prevention, delay or treatment of neurodegenerative disease. Cell test results show that Prussian blue nanoparticles can reduce the level of ROS in nerve cells stimulated by hydrogen peroxide and increase the proportion of living cells in nerve cells stimulated by hydrogen peroxide. Animal test results show that Prussian blue nanoparticles can significantly reduce the expression level of oxidative stress markers in the hippocampus of mouse models of neurodegenerative disease, and significantly improve the learning and memory abilities and ameliorate motor dysfunction of mouse models of neurodegenerative disease.

Abstract: An ultrasonic diagnostic imaging system acquires a sequence of image data as a bolus of contrast agent washes into and out of a region of interest (ROI) which may contain a lesion. The image data of contrast intensity is used to compute a time-intensity curve at each point in the ROI. Levels of a time-intensity curve are set to define a rise rime period when contrast perfuses the ROI, an enhancement time period when a maximal amount of contrast is sustained in the ROI, and a fall time period when contrast washes out of the ROI. One or more of the time period parameters for the points in the ROI are used to form a parametric contrast image, which is used to identify a lesion in the ROI and its border.

Abstract: The tunable optical filter is provided, comprising an optical means for separating an input optical signal into a tunable drop optical signal and an output optical signal, wherein the output optical signal is directed back along the same path as the input optical signal. One embodiment of the invention comprises an optical circulator, a pair of polarization beam splitters, a pair of half-wave plates, an optical thin-film filter, a rotatable mirror, a spatially fixed mirror. Optical wavelengths are selected by making angular adjustments to the optical thin-film filter and the rotatable mirror, which are rotated by the same angle. A corresponding method for spectrally splitting and spatially separating an input optical signal into an output optical signal and a drop optical signal is also provided.
