INTRODUCTION Regional citrate anticoagulation (RCA) is gaining popularity in continous renal replacement therapy (CRRT) for critically ill patients. The risk of citrate toxicity is a primary concern during the prolonged process. The aim of this study was to assess the pharmacokinetics of citrate in critically ill patients with AKI, and used the kinetic(More)
BACKGROUND To examine the characteristics of oxidative stress in patients with acute kidney injury (AKI) and investigate the association between plasma nitrotyrosine levels and 90-day mortality in patients with AKI. METHODOLOGY/PRINCIPAL FINDINGS 158 patients with hospital-acquired AKI were recruited to this prospective cohort study according to RIFLE(More)
Vascular calcification is an actively regulated process similar to bone formation. Advanced oxidation protein products (AOPPs) have been demonstrated to be novel markers of oxidant-mediated protein damage. The present study investigated the role of AOPPs in inducing osteoblastic trans-differentiation and calcification of smooth muscle cells in vitro. We(More)
BACKGROUND/AIMS This study aimed to examine antioxidants in patients with acute kidney injury (AKI) and determine whether serum protein thiol levels are associated with all-cause 90-day mortality in patients with hospital-acquired AKI. METHODS According to the RIFLE criteria, 160 patients with hospital-acquired AKI were enrolled in our prospective cohort(More)
The paper introduces a simple and efficient approach to calibrate camera in the parallel binocular stereo vision system, which uses numerical analysis based on least square error to obtain the relative difference of the two cameras' principle point and extrinsic parameters. First, we use Zhang Plane-based Calibration Method to verify the intrinsic(More)
Moving objects segmentation is the foundation of intelligent moving body information collection. In the monocular vision system, it is too difficult to segment the foreground from background when their grayscale and color are similar. Compared with the grayscale and color, the scenery depth are less susceptible to external environment, if depth information(More)
