Dynamic background modeling is an essential task for numerous visual surveillance applications such as incident detection and traffic management. Adaptive mixture models and nonparametric models are two popular methods for background modeling at present. However, it is usually too costly to perform for the both methods in real time, since they are both(More)
Danshensu, a type of dihydroxyphenyl lactic acid, is one of the most abundant active phenolic acids in the dried root of Salvia miltiorrhizae (Lamiaceae)--widely used traditional Chinese medicine. The effects of danshensu on platelet aggregation and thrombus formation in rats were examined using various methods. It was found that danshensu significantly(More)
This paper presents an efficient underwater video-coding algorithm suitable for the purpose of underwater acoustic channel transmission. The algorithm mainly consists of three modules, namely preprocessing of underwater images, global motion estimation, and hybrid global-local motion compensation. A wavelet transform based preprocessing approach is employed(More)
The effect of forskolin on corticostriatal synaptic transmission was examined by recording excitatory postsynaptic currents (EPSCs) in rat brain slices using the whole-cell voltage-clamp technique. Forskolin produced a dose-dependent increase of corticostriatal EPSCs (1, 3, 10, and 30 microM) immediately after its treatment, and the increase at 10 and 30(More)
To overcome the problem of registration error accumulation, this paper presents a fast video mosaic approach especially suitable for real-time observation of large static scenes. Different from the traditional video mosaic algorithm based on pair-wise local registration, the proposed new approach can directly compute the projective transform between the(More)
Glioblastoma (GBM) is the most frequent and aggressive tumour in the central nervous system. Many studies have demonstrated that upregulation of the NF-κB onco-pathway is accompanied by the acquisition of Temozolomide (TMZ) resistance in GBM cells. Here, we show that RGFP109, a selective histone deacetylase (HDAC1 and HDAC3) inhibitor, overcomes TMZ(More)
High levels of glucocorticoids (GCs) have been reported to damage normal hippocampal neurons, and such damage has been positively correlated with major depression (MD) and chronic stress. Our previous study showed that HDAC6 might be a potential target to regulate GC-induced glucocorticoid receptor (GR) translocation to the mitochondria and subsequent(More)
