The role of carotid stenosis ultrasound scale in the prediction of ischemic stroke.

Introduction: To improve the accuracy of ultrasound techniques for the assessment of carotid stenosis, we designed a novel carotid artery stenosis ultrasound scale (CASUS), and evaluated its accuracy, reliability, and its value in predicting the occurrence of cardiovascular and cerebrovascular diseases in a prospective study.

Methods: A total of 750 patients with first-time ischemic stroke and hospitalized within 24 h were enrolled in the study. Using color Doppler ultrasound (CDUS), the degree of stenosis and blood flow (BF) in bilateral internal carotid arteries (ICA) and the V1-V3 segment of vertebral arteries (VA) was assessed.

Hollow Carbon Microspheres/MnO Nanosheets Composites: Hydrothermal Synthesis and Electrochemical Behaviors.

This article reported the electrochemical behaviors of a novel hollow carbon microspheres/manganese dioxide nanosheets (micro-HC/nano-MnO) composite prepared by an in situ self-limiting deposition method under hydrothermal condition. The results of scanning electron microscopy reveal that MnO nanosheets homogeneously grow onto the surface of micro-HC to form a loose-packed microstructure. The quantity of MnO required in the electrode layer has thereby been reduced significantly, and higher specific capacitances have been achieved.
