| 1 | Probucol inhibits LPS-induced microglia activation and ameliorates brain ischemic injury in normal and hyperlipidemic mice显示文摘瞄准:增加的证据建议那 probucol,有抗氧化剂活动的一个类脂化合物阴沉的代理人,可能为有经由在胆固醇和 neuroinflammation 的减小的 hyperlipidemia 的 ischemic 击的治疗有用。在这研究,我们检验了 probucol 是否能在正常和 hyperlipidemic mice.Methods 经由 anti-neuroinflammatory 行动免于大脑 ischemic 损害:主要老鼠 microglia 和鼠科的 BV2 microglia 不为 3 h,和版本暴露于 lipopolysaccharide (LPS ) , PGE2, IL-1β并且在 NF-κ 的 IL-6,以及变化; B,表明小径的 MAPK 和 AP-1 被估计。ApoE 击倒老鼠被喂包含 0.004% 的一本高脂肪的食谱, 0.02% , 0.1%(wt/wt ) 为 10 个星期的 probucol 而正常 C57BL/6J 老鼠收到了 probucol (3, 10, 30 mg· kg -1·d-1, po ) 为 4 d。然后,所有老鼠通过中间的服的动脉吸藏(MCAO ) 受到焦点的服的局部缺血。神经病学的赤字被获得在外科以后的 24 h,然后大脑为测量服的梗塞尺寸和支持 inflammatory mediators.Results 的生产被移开:在对待 LPS 的 BV2 房间和主要 microglial 房间,有 probucol 的预告的处理(1, 5, 10 μ mol/L ) dose-dependently 禁止了版本没有, PGE2, IL-1β并且 IL-6,它发生在抄写铺平。而且, probucol 的禁止的行动与 NF-κ 的 downregulation 被联系;表明小径的 B, MAPK 和 AP-1。在有 MCAO 的正常鼠标, probucol 的管理前 dose-dependently 减少了梗塞卷和改进神经病学的功能。这些效果被支持 inflammatory 调停人的减少的生产伴随(iNOS, COX-2, IL-1, IL-6 ) 。在 ApoE 击倒,老鼠喂了一本高脂肪的食谱, 0.1% probucol 的管理前显著地减少了梗塞体积,改进了跟随 MCAO 的神经病学的赤字,并且减少全部胆固醇并且 LDL 胆固醇 levels.Conclusion:Probucol 禁止导致 LPS 的 microglia 激活并且改善在经由它的 anti-neuroinflammatory 行动的正常和 hyperlipidemic 老鼠的服的 ischemic 损害,建议那 probucol 为 ischemic 击和 hyperlipidemia 为病人的治疗有潜力与或在风险。 | Yeon Suk JUNG Jung Hwa PARK Hyunha KIM So Young KIM Ji Young HWANG Ki Whan HONG Sun Sik BAE Byung Tae CHOI Sae-Won LEE Hwa Kyoung SHIN | 2016 | Acta Pharmacologica Sinica2016,37,8: | 16 |
| 5 | Development of large acceptance multi-purpose spectrometer in Korea for symmetry energy显示文摘The Rare Isotope Accelerator complex for ONline experiments(RAON) is a new radioactive ion beam accelerator facility under construction in Korea. The large acceptance multi-purpose spectrometer(LAMPS) is one of the experimental devices for nuclear physics at RAON. It focuses on the nuclear symmetry energy at supra-saturation densities. The LAMPS Collaboration has developed and constructed various detector elements, including a time projection chamber(TPC) and a forward neutron detector array. From the positron beam test, the drift velocity of the secondary electrons in the TPC is 5:3±0:2 cm/ls with P10 gas mixture, and the position resolution for pads with dimensions of 4×15 mm^2 is in the range of$ 0.6–0.8 mm, depending on the beam position. From the neutron beam test, the energy resolution of the prototype neutron detector module is determined to be 3.4%, and theposition resolution is estimated to be better than 5.28 cm.At present, the construction of the LAMPS neutron detector system is in progress. | Byungsik Hong Jung Keun Ahn Gyeonghwan Bak Jamin Jo Minho Kim Eun Joo Kim Young Jin Kim Young Jun Kim Minjung Kweon Hanseul Lee Hyo Sang Lee Jong-Won Lee Jung Woo Lee Kyong Sei Lee Byul Moon Dong Ho Moon Benard Mulilo Jaebeom Park Min Sang Ryu Hyunha Shim LAMPS Collaboration | 2018 | Nuclear Science and Techniques2018,29,12: | 1 |
