METHODS: MK-801 (10 μM) was administered to rats by unilateral intracerebroventricular infusion (i.c.v.) 20 min prior to preconditioning. The rats were subjected to global cerebral ischemia (GCI) by four-vessel occlusion Rats were subjected to Sham operation (Sham), 8-min global cerebral ischemia + 3d reperfusion (R3d); ischemic preconditioning (P + R3d), ischemic preconditioning + saline + 3d reperfusion (saline), ischemic preconditioning + MK-801 pretreatment + 3d reperfusion (MK-801). Western blotting analysis of the effects of ERK5 and JNK3 in preconditioning regulation and protein expression with or without CIP in hippocampal CA1 regions. RESULTS: global cerebral ischemia significantly increased p-c-Jun as compared to Sham controls. In contrast, preconditioning abolished the global ischemia-induced elevation of p-c-Jun. The effect of preconditioning on p-c-Jun was significantly reversed by pretreatment with the ERK5-AS, while vehicle alone pretreatment had no effect. The changing trend of the C-fos expression was all opposite to that of p-cJun.; Semi-quantitative analysis of the levels of p-c-jun and c-fos levels from the different groups. The influence of ERK5-AS on protein binding activity of p-Bad in cytoplasm and 14-3-3 protein. Immunoprecipitation results showed that Preconditioning significantly increased the protein binding activity of p-Bad and 14-3-3 as compared to 8-min global cerebral ischemia. ERK5-AS apparent reversed the up-regulation. CONCLUSION global cerebral ischemia significantly increased p-c-Jun preconditioning abolished the global ischemia-induced elevation of p-c-Jun. Preconditioning significantly increased the protein binding activity of p-Bad and 14-3-3, ERK5-AS apparent reversed the up-regulation.","PeriodicalId":383024,"journal":{"name":"2014 IEEE Workshop on Electronics, Computer and Applications","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115834837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is important to understand factors that affect space charge formation in oil/paper insulation system. All the researches on the space charge characteristics of oil-paper insulation are all based on the oil impregnated insulation paper. In this paper, the space charge dynamic behavior of the oil impregnated insulation pressboard and the mixed insulation with a combination of oil gap and oil impregnated insulation pressboard were both studied. The oil property effect on the charge and electric field distribution behavior were discussed. The injected charge in aged oil impregnated insulation pressboard has a higher migration rate than that in new oil impregnated insulation pressboard. Compared with the oil impregnated insulation pressboard, a lot of space charges accumulate at the interface between oil and pressboard, which leads to obvious electric field distortion in oil gap and in oil impregnated insulation pressboard. The charge injected in new oil-paper insulation is more difficult to dissipation than that in aged oil-paper insulation.","PeriodicalId":383024,"journal":{"name":"2014 IEEE Workshop on Electronics, Computer and Applications","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124405745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
