Oxidative stress-induced neuronal death has an important role in the pathogenesis of neurodegenerative disorders. The effects and mechanisms of action of the total flavonoids (TFs) from Rosa laevigata Michx fruit against hydrogen peroxide (H2O2)-induced oxidative injury in PC12 cells were investigated in this study. The results demonstrated that the TFs(More)
Dehydroepiandrosterone sulfate (DHEAS) is one of the most important neuroactive steroids. The present study examined the effect of DHEAS on spontaneous and evoked glutamate release in the pyramidal cells of layers V and VI of the rat prelimbic cortex by using whole-cell patch-clamp recordings in slices and further investigated its mechanism. The results(More)
This paper describes the SemEval 2016 shared task on Aspect Based Sentiment Analysis (ABSA), a continuation of the respective tasks of 2014 and 2015. In its third year, the task provided 19 training and 20 testing datasets for 8 languages and 7 domains, as well as a common evaluation procedure. From these datasets, 25 were for sentence-level and 14 for(More)
Noun phrases (NP) in a product review are always considered as the product attribute candidates in previous work. However, this method limits the recall of the product attribute extraction. We therefore propose a novel approach by generalizing syntactic structures of the product attributes with two strategies: intuitive heuristics and syntactic structure(More)
The neuronal nitric oxide synthase (nNOS) is predominantly expressed in nervous tissues and subject to complex transcriptional controls. To determine the effect of acetylation on nNOS expression, human neuroblastoma SK-N-SH cells were treated with trichostatin A (TSA), a histone deacetylase inhibitor. As a consequence, total and exon 1f-specific nNOS mRNA,(More)
This paper focuses on the task of colloca-tion polarity disambiguation. The collocation refers to a binary tuple of a polarity word and a target (such as ⟨long, battery life⟩ or ⟨long, startup⟩), in which the sentiment orientation of the polarity word (" long ") changes along with different targets (" battery life " or " startup "). To disambiguate a(More)
Recent studies suggest a role of the proteasome activator, REGγ, in cancer progression. Since there are limited numbers of known REGγ targets, it is not known which cancers and pathways are associated with REGγ. REGγ protein expressions in four different cancers were investigated by immunohistochemistry (IHC) analysis. Following NCBI Gene Expression Omnibus(More)
This study examined the toxic effects of microcystins on mitochondria of liver and heart of rabbit in vivo. Rabbits were injected i.p. with extracted microcystins (mainly MC-RR and -LR) at two doses, 12.5 and 50 MC-LReq. microg/kg bw, and the changes in mitochondria of liver and heart were studied at 1, 3, 12, 24 and 48 h after injection. MCs induced damage(More)
