1Contrasting Effects of Ethylene Biosynthesis on Induced Plant Resistance against a Chewing and a Piercing-Sucking Herbivore in Rice显示文摘乙烯是有在草食动物抵抗上对比效果的压力荷尔蒙。然而,这些差别是否植物特定或草食动物特定,仍然保持未知。我们克隆米饭 1-aminocyclopropane-1-carboxylic 酸(ACC ) synthase 基因, OsACS2,其抄本响应由二个重要害虫的机械伤害和群袭是很快起来调整的:有斑纹的茎 borer (SSB ) Chilo suppressalis 和棕色的 planthopper (BPH ) Nilaparvata lugens。OsACS2 (当交流) 的 Antisense 表示减少了得到的乙烯排放,得到 SSB 的胰岛素朊酶禁止者(TrypPI ) 活动,导致 SSB 的不稳定的版本,和 SSB 抵抗。ACC 的外长的申请恢复了 TrypPI 活动和 SSB 抵抗。与 SSB 相对照, BPH 群袭在当交流线增加了不稳定的排放。因此, BPH 喜欢喂并且在上产卵野类型(WT ) 能被归因于二讨厌的 volatiles, 2-heptanone 和 2-heptanol 的 plantsan 效果,那被当交流植物在更高的数量射出。BPH 蜜露排泄被减少,生来的敌人吸引力在当交流线被提高,导致到 BPH 的更高全面的抵抗。这些结果证明发信号的乙烯对咀嚼和一只穿透吸昆虫在米饭防卫回答和电阻上有形成对照的、草食动物特定的效果,并且可以调停在不同的喂的草食动物之间的抵抗交易在米饭的行业协会。Jing Lu Jiancai Li Hongping Ju Xiaoli Liu Matthias Erb Xia Wang Yonggen Lou 2014Molecular Plant2014,7,11:15
2Protective effects of ischemic preconditioning and application of lipoic acid prior to 90 min of hepatic ischemia in a rat model显示文摘AIM: To compare different preconditioning strategies to protect the liver from ischemia/reperfusion injury focusing on the expression of pro- and anti-apoptotic proteins. Interventions comprised different modes of ischemic preconditioning (IP) as well as pharmacologic pretreatment by α-lipoic acid (LA). METHODS: Several groups of rats were compared: sham operated animals, non-pretreated animals (nt), animals receiving IP (10 min of ischemia by clamping of the portal triad and 10 min of reperfusion) prior to sustained ischemia, animals receiving selective ischemic preconditioning (IPsel, 10 min of ischemia by selective clamping of the ischemic lobe and 10 min of reperfusion) prior to sustained ichemia, and animals receiving 500 μmol α-LA injected i.v. 15 min prior to the induction of 90 min of selective ischemia. RESULTS: Cellular damage was decreased only in the LA group. TUNEL-positive hepatocytes as well as necrotic hepatocyte injury were also decreased only by LA (19 ± 2 vs 10 ± 1, P < 0.05 and 29 ± 5 vs 12 ± 1, P < 0.05). Whereas caspase 3- activities in liver tissue were unchanged, caspase 9- activity in liver tissue was decreased only by LA pretreatment (3.1 ± 0.3 vs 1.8 ± 0.2, P < 0.05). Survival rate as the endpoint of liver function was increased after IP and LA pretreatment but not after IPsel. Levels of lipid peroxidation (LPO) in liver tissue were decreased in the IP as well as in the LA group compared to the nt group. Determination of pro- and anti-apoptotic proteins showed a shift towardsanti-apoptotic proteins by LA. In contrast, both our IP strategies failed to influence apototic cell death. CONCLUSION: IP, consisting of 10 min of ischemia and 10 min of reperfusion, protects only partly against ischemia/reperfusion injury of the liver prior to 90 min of selective ischemia. IPsel did not influence ischemic tolerance of the liver. LA improved tolerance to ischemia, possibly by downregulation of pro-apoptotic Bax.Friedrich Duenschede Kirsten Erbes Nina Riegler Patrick Ewald Achim Kircher Stefanie Westermann Arno Schad Imke Miesmer Simon Albrecht-Schck Ines Gockel Alexandra K Kiemer Theodor Junginger 2007World Journal of Gastroenterology2007,13,27:8
3Reduction of ischemia reperfusion injury after liver resection and hepatic inflow occlusion by α-lipoic acid in humans显示文摘AIM: To evaluate the protective effects of precondition- ing by α-lipoic acid (LA) in patients undergoing hepatic resection under inflow occlusion of the liver. METHODS: Twenty-four patients undergoing liver re- section for various reasons either received 600 mg LA or NaCl 15 min before transection performed under inflow occlusion of the liver. Blood samples and liver wedge bi- opsy samples were obtained after opening of the abdo- men immediately after inflow occlusion of the liver, and 30 min after the end of inflow occlusion of the liver. RESULTS: Serum levels of aspartate transferase and alanine transferase were reduced at all time points in patients who received LA in comparison to those who received NaCL. This was accompanied by reduced histo- morphological features of oncosis. We observed TUNEL- positive hepatocytes in the livers of the untreated patients, especially after 30 min of ischemia. LA attenu- ated this increase of TUNEL-positive hepatocytes. Under preconditioning with LA, ATP content was significantly enhanced after 30 min of ischemia and after 30 min of reperfusion. CONCLUSION: This is the first report on the poten- tial for LA reducing ischemia/reperfusion injury (IRI) of the liver in humans who were undergoing liver surgery. Beside its simple and rapid application, side effects did not occur. LA might therefore represent a new strategy against hepatic IRI in humans.Fritz Dünschede Kirsten Erbes Achim Kircher Stefanie Westermann Joachim Seifert Arno Schad Kempski Oliver Alexandra K Kiemer Junginger Theodor 2006World Journal of Gastroenterology2006,12,42:6
4硫酸溶液中1,1′-硫代羰基二咪唑在碳钢上的吸附及缓蚀影响和碘离子的增强效应(英文)显示文摘The inhibition effect of 1,1′-thiocarbonyldiimidazole (TCDI) on the corrosion behaviors of mild steel (MS) in 0.5 mol·L-1 H2SO4 solution was studied with the help of potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and linear polarization resistance (LPR) techniques. The effect of immersion time on the inhibition effect of TCDI was also investigated over 72 h. For the long-term tests, hydrogen evolution with immersion time (VH2-t) was measured in addition to the three techniques already mentioned. The thermodynamic parameters, such as adsorption equilibrium constant (Kads) and adsorption free energy (△Gads) values, were calculated and discussed. To clarify inhibition mechanism, the synergistic effect of iodide ion was also investigated. The potential of zero charge (PZC) of the MS was studied by electrochemical impedance spectroscopy method, and a mechanism of adsorption process was proposed. It was demonstrated that inhibition efficiency increased with the increase in TCDI concentration and synergistically increased in the presence of KI. The inhibition efficiency was discussed in terms of adsorption of inhibitor molecules on the metal surface and protective film formation.SOLMAZ R MERT M.

6Parvovirus B19 induced hepatic failure in an adult requiring liver transplantation显示文摘Parvovirus B19 induced acute hepatitis and hepatic failure have been previously reported, mainly in children. Very few cases of parvovirus induced hepatic failure have been reported in adults and fewer still have required liver transplantation. We report the case of a 55-year-old immunocompetent woman who developed fulminant hepatic failure after acute infection with Parvovirus B19 who subsequently underwent orthotopic liver transplantation. This is believed to be the first reported case in the literature in which an adult patient with fulminant hepatic failure associated with acute parvovirus B19 infection and without hematologic abnormalities has been identified prior to undergoing liver transplantation. This case suggests that Parvovirus B19 induced liver disease can affect adults, can occur in the absence of hematologic abnormalities and can be severe enough to require liver transplantation.Darin S Krygier Urs P Steinbrecher Martin Petric Siegfried R Erb Stephen W Chung Charles H Scudamore Andrzej K Buczkowski Eric M Yoshida 2009World Journal of Gastroenterology2009,15,32:3
7青光眼患者血清抗视网膜抗原的抗体轮廓质谱分析显示文摘目的比较原发性开角型青光眼(POAG)患者与正常对照(CTRL)者间的抗体轮廓差异。方法病例对照研究。将44例POAG患者与48例CTRL者的血清分别加入到含有预洗Dyna珠-G蛋白的反应管中,以捕获人免疫球蛋白G(IgG)抗体,形成的IgG—G蛋白复合体用来捕获目标抗原(匀质化牛视网膜组织)。经洗提后获得的抗原蛋白通过“表面增强激光解吸附-电离-飞行时间-质谱”仪进行检测。采用Proteomic software project统计学软件,对两组质谱数据连同受检者年龄和性别等参数,自动进行t检验和初步多变量判别分析;随后采用Statistica version8.0统计学软件,进行包括抗原蛋白质谱数据、蛋白质芯片类型和激光解吸附-电离能量等的多变量判别分析。结果CTRL组的平均质谱强度为4244.427±4721.115,POAG组为4049.864±4083.819,两组间差异有统计学意义(F=1.340,P〈0.01);在POAG患者中,出现了部分高调节免疫反应,但主要表现为低调节免疫反应。结论在POAG患者与CTRL者之间存在明显的抗体轮廓差异,在POAG组中出现的低调节免疫反应表明部分患者可能与“异常免疫”有关。严良 Joachim S.
