        Paint Removal of Airplane & Water Jet Application

        Xue, Sheng-Xiong,Chen, Zheng-Wen,Ren, Qi-Le,Su, Ji-Xin,Han, Cai-Hong,Pang, lei Korean Society for Fluid machinery 2014 International journal of fluid machinery and syste Vol.7 No.3

        The paint removal and recoating are the very important process in airplane maintenance. The traditional technology is to use the chemical way corroding the paint with paint remover. For changing the defects, corrosion & pollution & manual working, of the traditional technology, the physical process which removes the paint of airplane with 250MPa/250kW ultra-high pressure rotary water jetting though the surface cleaner installed on the six axes robot is studied. The paint layer of airplane is very thin and close. The contradiction of water jetting paint removal is to remove the paint layer wholly and not damage the surface of airplane. In order to solve the contradiction, the best working condition must be reached through tests. The paint removal efficiency with ultra-high pressure and move speed of not damaged to the surface. The move speed of this test is about 2m/min, and the paint removal efficiency is about $30{\sim}40m^2/h$, and the paint removal active area is 85-90%. No-repeat and no-omit are the base requests of the robot program. The physical paint removal technology will be applied in airplane maintenance, and will face the safety detection of application permission.

        Bupropion for Interferon-Alpha-Induced Depression in Patients with Hepatitis C Viral Infection: An Open-Label Study

        Wei-Chun Chen,Hsueh-Chou Lai,Wen-Pang Su,Mahalakshmi Palani,Kuan-Pin Su 대한신경정신의학회 2015 PSYCHIATRY INVESTIGATION Vol.12 No.1

        Interferon (IFN)-α therapy for chronic hepatitis C virus (HCV) infection is frequently associated with major depressive episodes. Bupropion, a commonly used antidepressant agent, has recently found to have strong anti-inflammatory effects in animal models. Despite of the theoretical relevancy, the antidepressant effect of bupropion in IFN-alpha-induced depression has never been studied. Ten HCV patients with IFN-α-induced depression were recruited to receive 8-week bupropion treatment and were assessed every 2 weeks for depressive symptoms by the Hamilton rating scale for depression (HAMD) and somatic symptoms by the Neurotoxicity Rating Scale (NRS). Four of the 10 patients met the criteria for remission (total HAMD scores≤7), and 5 patients met the criteria for response (at least 50% reduction in total HAMD scores). In addition, 5 patients had 50% decreases in NRS for neuropsychiatric symptoms. This preliminary open-label study suggests that bupropion is effective in treating IFN-alpha-induced depressive and somatic symptoms.

      • Tea seed saponin(TSS) improve lipid metabolism and oxidative stress in high fat diet(HFD)-induced obese mice

        Shuang Liu,Huishan Qin,Yanmin Su,Jiali Li,Wenjing Cao,Wen He,Zhen Zeng,Qi Qi Pang,Jia-Le Song 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

        To investigate the effect of TSS on lipid metabolism and oxidative stress in HFD mice. The body weight and food intake were observed. The serum SOD, MDA, GSH, TC, TG, HDL-C, LDL-C were determined by kits. Western Blotting was used to detect the levels of PPAR-γ, AMPK, SIRT1 and PGC-1α. TSS treatment reduced the body weight, Lee"s index and fat organ indices of mice in the HFD group. Compared with the control(CON) group, the serum TC, TG and LDL-C in the HFD group were increased, Administrated with TSS can improve abnormal blood lipid levels. Compared with the CON group, the serum SOD level in HFD group was significantly reduced(P<0.05), and MDA level was increased; while the levels of serum MDA in the TSS group decreased and SOD level increased. The pathological sections showed that TSS could improve the degree of hepatic steatosis. TSS also increased the levels of PPAR-γ, AMPK, SIRT1 and PGC-1α, and the effect of the high-dose group was the most significant. TSS can reduce body weight and fat accumulation, improve lipid metabolism disorder and oxidative stress caused by HFD.
