Smart phones is bringing about emerging potentials in mobile visual search. Extensive research efforts have been made in compact visual descriptors. However, directly extracting visual descriptors on a mobile device is computationally intensive and time consuming. Towards low bit rate visual search, we propose to deeply compress query images by learning a(More)
A multicomponent DNA vaccine, encoding Toxoplasma gondii GRA1 and SAG1, was constructed and tested for its ability to confer protection. BALB/c mice were challenged with tachyzoites of the virulent T. gondii RH strain at 4 weeks following the last immunization, and immune responses and survival times were observed. The results show that vaccination by the(More)
Müller cell gliosis, which is characterized by upregulated expression of glial fibrillary acidic protein (GFAP), is a universal response in many retinal pathological conditions. Whether down-regulation of inward rectifying K+ (Kir) channels, which commonly accompanies the enhanced GFAP expression, could contribute to Müller cell gliosis is poorly(More)
Truncated tau is widely detected in Alzheimer's disease brain, and caspase-3 has been considered as a major executioner for tau truncation at aspartate421 (D421), according to its capability of cleaving recombinant tau in vitro. Here we investigated the relationship between D421 truncated tau and caspase-3 in two transgenic mouse models for tauopathies. In(More)
The reductions of nitrophenols catalyzed by nitroreductase from E. coli in the presence of NADH were investigated in this paper. 4-Aminophenol and 4-hydroxylaminophenol were found in the reductive products of 4-nitrophenol and the maximum reductive ratio was about 83.49% when the reaction time was 70 min; 4,6-dinitro-2-pimelie kelone was found in the(More)
With the popularization of mobile devices, recent years have witnessed an emerging potential for mobile landmark search. In this scenario, the user experience heavily depends on the efficiency of query transmission over a wireless link. As sending a query photo is time consuming, recent works have proposed to extract compact visual descriptors directly on(More)
AIM To investigate the relationships between c-fos expression and oxidative stress or inflammation in the liver induced by acute cadmium (Cd) exposure. METHODS Sixty male Sprague-Dawley rats were randomly assigned to 1 of 6 groups, 10 rats in each group. They were intragastrically pretreated with distilled water, distilled water, vitamin E (50 mg/100 g(More)
Intracerebral hemorrhage (ICH), accounting for 15-20% of strokes, can cause significant brain injury and life long neurological deficits. We investigated whether treadmill exercise rehabilitation could improve brain repair after ICH and whether involvement of NFG-TrkA and BDNF-TrkB signaling could be observed during repair period in an experimental mouse(More)
We investigated possible involvement of a calpain/p35-p25/cyclin-dependent kinase 5 (Cdk5) signaling pathway in modifying NMDA receptors (NMDARs) in glutamate-induced injury of cultured rat retinal neurons. Glutamate treatment decreased cell viability and induced cell apoptosis, which was accompanied by an increase in Cdk5 and p-Cdk5(T15) protein levels.(More)
