BACKGROUND We investigated the clinical-pathological features and the prognosis of thrombotic thrombocytopenic purpura (TTP) in patients with lupus nephritis (LN). METHODS A retrospective analysis was performed on the clinical-pathological data and prognosis in 8 patients with LN complicating with TTP. RESULTS Thrombocytopenia and hemolytic anemia,(More)
Investigations of the phytoplankton, zooplankton, zoobenthos and aquatic vegetation in Lake Qiluhu were carried out in February, 2009. Over the whole lake, 13 sampling sites were set up for the analysis of phytoplankton and zooplankton, and 22 profiles for the collection of macrophytes and zoobenthos. In the survey, 7 phyla, 65 algae species were(More)
The purpose of this study was to investigate the role of pore size on tissue ingrowth and neovascularization in porous bioceramics under the accurate control of the pore parameters. For that purpose, β-tricalcium phosphate (β-TCP) cylinders with four different macropore sizes (300-400, 400-500, 500-600 and 600-700 µm) but the same interconnection size (120(More)
In this paper, we present efficient schemes to utilize multiple frames that contain the same text to get every clear word from these frames. Firstly, we use multiple frame traction to reduce text detection false alarms. And then detect and joint every clear text block from those frames to form a clearer integration frame. Later we uses Otsu threshold method(More)
(range 3–12 days). No complications occurred during any of the treatment regimens. Although a relapse occurred 15 days after completion of treatment in the oldest patient, who had received cefotaxime and oral tosufl oxacin, re-treatment cured the infection without fecal carriage. The high attack rate may refl ect the high sensitivity of adolescents to(More)
The development of VLSI technology results in the dramatically improvement of the performance of integrated circuits. However, it brings more challenges to the aspect of reliability. Integrated circuits become more susceptible to soft errors. Therefore, it is imperative to study the reliability of circuits under the soft error. This paper implements three(More)
This paper investigates a mean-variance portfolio selection problem in continuous time with fixed and proportional transaction costs. Utilizing the dynamic programming, the Hamilton-Jacobi-Bellman (HJB) equation is derived, and the explicit closed form solution is obtained. Furthermore, the optimal strategies and efficient frontiers are also proposed for(More)
Porcine reproductive and respiratory syndrome virus (PRRSV), the causative agent of porcine reproductive and respiratory syndrome (PRRS), causes serious health problems in swine, resulting in great economic losses to the swine industry worldwide. The porcine reproductive and respiratory syndrome (PRRS) killed virus (KV) vaccine has been widely used in China(More)
