Expression of neuroglobin in ocular hypertension induced acute hypoxic-ischemic retinal injury in rats

引用

International Journal of Ophthalmology(English edition) 2011年第4期4卷 393-395页

作者： Shao-Yang shi Xue-Mei Feng you li Xun li and Xiao-Long Chen Department of Ophthalmology Shengjing Hospital of China Medical University Shenyang 11004 Liaoning Province China

AIM: To investigate the Expression of neuroglobin (Ngb) in the retina of rats with ocular hypertension induced acute retinal hypoxic-ischemic injury. METHODS: Seventy Wistar rats were divided into 7 groups randomly. The Experimental model was induced by elevation of intraocular pressure via anterior chamber canula insertion in the left eyes and the fellow eyes were preserved as normal controls. The retinal tissues were taken at 1, 5, 10, 15, 20, 30 and 60 minutes after hypoxic-ischemia injury. Protein was extracted, and then analyzed by Western-blot method. SPSS was used for statistical analysis. RESULTS: The time-depended expressions of Ngb were observed. The level of Ngb increased rapidly at 1 minute after ischemia and reached to the peak at 5 minutes, which had significant difference from that of control group (P 0.05). CONCLUSION: The expression of Ngb in retinal tissue increased rapidly after hypoxic-ischemic injury in rats, suggesting that Ngb may play an important role in the process of acute retinal hypoxic-ischemic injury.

Multi-policy threshold signature with distinguished signing authorities

The Journal of China Universities of Posts and Telecommunications 2011年第1期18卷 113-120页

作者： WANG Feng ZHOU you-sheng GU li-ze ZHENG shi-hui YANG Yi-xian Information Security Center State Key Laboratory of Networking and Switching Technology Beijing University of Posts and Telecommunications Beijing 100876 China Key Laboratory of Network and Information Attack and Defence Technology Ministry of Education Beijing University of Posts and Telecommunications Beijing 100876 China

Threshold signature plays an important role to distribute the power of a single authority in modem electronic society. In order to add functions and improve efficiency of threshold signatures, a multi-policy threshold signature scheme with distinguished signing authorities is proposed. In the scheme two groups can sign and verify each other, so the scheme is two-way signing and verifying. Moreover, the threshold values of the two groups can change with the security classification of the signing document, every discretionary signatory only signs a small part of the document instead of the whole one, so the bandwidth of data transmission for group signature construction can be reduced and the size of group signature is equivalent to that of any individual signature.

Divergence, evolution and adaptation in ray-finned fish genomes

With the rapid development of next-generation sequencing technologies and bioinformatics, over 50 ray-finned fish genomes by far have been sequenced with high quality. The genomic work provides abundant genetic resources for deep understanding of divergence, evolution and adaptation in the fish genomes. They are also instructive for identification of candidate genes for functional verification, molecular breeding, and development of novel marine drugs. As an example of other omics data, the Fish-T1 K project generated a big database of fish transcriptomes to integrate with these published fish genomes for potential applications. In this review, we highlight the above-mentioned recent investigations and core topics on the ray-finned fish genome research, with a main goal to obtain a deeper understanding of fish biology for theoretical and practical applications.
