that the prevalence of EBOV in these tested bat species is greater than that previously detected in E. helvum bats (1/262 serum samples) (1). The higher estimated prevalence in these species occurred despite the fact that E. helvum bats live in large colonies comprising several million animals, which make the species an ideal host for acute RNA virus(More)
Rabbit hemorrhagic disease (RHD) is contagious and highly lethal. Commercial vaccines against RHD are produced from the livers of experimentally infected rabbits. Although several groups have reported that recombinant subunit vaccines against rabbit hemorrhagic disease virus (RHDV) are promising, application of the vaccines has been restricted due to high(More)
We describe the SpeakGoodChinese system that supports beginning students of Mandarin Chinese to produce tones correctly (http://speakgoodchinese.org/). Students pronounce a word spelled in pinyin notation and receive feedback from our system on their production of the tones. The novelty in our approach lies in the use of synthetic reference tone(s) produced(More)

Lysosome is a highly membrane-bound organelle which possesses a sequence of biological functions including protein degradation, cell signal transduction, plasma membrane repairment, homoeostasis, and autophagy. The lysosome contains more than 50 soluble acid hydrolases, and the acidification of lysosome is the most important biological characteristic. The(More)
The study of rabbit hemorrhagic disease virus (RHDV) has long been hindered by the absence of an in vitro culture system. In this study, using RHDV as a model, a series of DNA-based reporter replicons were constructed in which the firefly luciferase (Fluc) gene was fused in-frame with the open reading frame of the replicon. In this construct, the Fluc gene(More)
Nowadays, heat shock protein 90 (Hsp90), a highly conserved molecular chaperone, has become the target of antitumor drugs as a result of its close relationship with the occurrence and development, biological behavior, and prognosis of a tumor. Autophagy has attracted big attention recently for its paradoxical roles in cell survival and cell death,(More)
Rabbit hemorrhagic disease virus (RHDV), the causative agent of rabbit hemorrhagic disease, is an important member of the caliciviridae family. Currently, no suitable tissue culture system is available for proliferating RHDV, limiting the study of the pathogenesis of RHDV. In addition, the mechanisms underlying RHDV translation and replication are largely(More)
Deoxycytidine kinase (dCK) is a key enzyme in deoxyribonucleoside salvage and the anti-tumor activity for many nucleoside analogs. dCK is activated in response to ionizing radiation (IR)-induced DNA damage and it is phosphorylated on Serine 74 by the Ataxia-Telangiectasia Mutated (ATM) kinase in order to activate the cell cycle G2/M checkpoint. However,(More)
Mitochondria as the critical powerhouse of eukaryotic cells play important roles in regulating cell survival or cell death. Under numerous stimuli, impaired mitochondria will generate massive reactive oxygen species (ROS) which participate in the regulation of vital signals and could even determine the fate of cancer cells. While the roles of mitochondria(More)
Two complete duck hepatitis virus type 1 (DHV-1) genomes, strain SY5 and its chicken embryos passage descendent vaccine strain ZJ-A, were compared and analyzed in order to identify possible sites of attenuation. Of the 205 nucleotide changes, 22 resulted in sense mutations, 174 produced nonsense mutations. Besides, there are 7 consistent nucleotides(More)
