In this study, we demonstrated a decreased level of mitochondrial DNA (mtDNA) with a large number of oxidized bases in hippocampi of rats with epilepsy induced by pilocarpine. In order to verify the underlying mechanism of mtDNA impairment, we detected the response of antioxidant defense system and mitochondrial base excision repair (mtBER) pathway.(More)
Diazoxide (DZ), a highly selective opener of the mitochondrial ATP-sensitive potassium (mitoK(ATP)) channel, has neuroprotective effects. However, the mechanism of DZ protecting hippocampal neurons against cell death in pilocarpine-induced seizures is unknown. In this study, we investigated DZ attenuating neuronal loss caused by pilocarpine-induced seizures(More)
Status epilepticus (SE) can cause severe neuronal loss and oxidative damage. Peroxisome proliferator-activated receptor gamma coactivator 1α (PGC-1α) can be neuroprotective by inducing the antioxidant system, so we evaluated the role of PGC-1α in SE. The expression of PGC-1α and one of its target genes, uncoupling protein 2 (UCP2), was upregulated after SE,(More)
Oxidative damage to mitochondrial DNA (mtDNA) has been implicated as an important mechanism underlying mitochondrial deficiency in epileptic seizures. In focusing on the role of the DNA repair pathway, we determined the response of the mitochondrial base excision repair (mtBER) pathway in pilocarpine-induced status epilepticus (SE) in hippocampi of male(More)
Chronic myelogenous leukemia (CML) is a neoplasm of myeloid progenitor cells expressing Bcr-Abl fusion protein. However, some patients with CML are less likely to respond to imatinib, the inhibitor of Bcr-Abl kinase. Recent studies showed that mTOR pathway can increase responses to imatinib. The analysis of mTOR pathway(More)
A novel TiO2 supported core-shell (Pd@Ag) bimetallic catalyst was fabricated via the sequential photodeposition method. The Ag shell effectively blocks the high coordination sites on the Pd core, and therefore pronouncedly enhances the ethylene selectivity for the catalytic hydrogenation of acetylene in excess ethylene.
Natural products are a rich resource for the discovery of therapeutic substances. By directly using 504 fine fractions from isolated traditional Chinese medicine plants, we performed a transgenic zebrafish based screen for anti-angiogenesis substances. One fraction, DYVE-D3, was found to inhibit the growth of intersegmental vessels in the zebrafish(More)
Contact resistance hinders the high performance of electrical devices, especially devices based on two-dimensional (2D) materials, such as graphene and transition metal dichalcogenide. To engineer contact resistance, understanding the resistance distribution and carrier transport behavior at the contact area is essential. Here, we developed a method that(More)
The present study evaluated whether the magnetic nanoparticles of Fe(3)O(4) (MNPs-Fe(3)O(4)) could enhance the activity of artesunate (ART), and to explore its potential mechanisms. Cytotoxicity of the copolymer of ART with MNPs-Fe(3)O(4) on K562 cells was detected by MTT assay and the apoptosis rate of K562 cells was measured by flow cytometry. Protein(More)
It is difficult to analyze and debug Cisco IOS with traditional debugging and disassembler tools such as GDB and IDA pro. These tools can't debug Cisco IOS in single step mode. This paper describes a dynamic analysis system based on a modification hardware emulator called Dynamips. Then, a new solution of inserting breakpoint with network events will be(More)
