The consumption of raw oyster has been linked to numerous foodborne gastroenteritis outbreaks caused by norovirus (NoV) in different countries of the world, including in China. This study investigated the prevalence of NoV and contamination levels in retail oysters taken from markets in Beijing and Qingdao in China. The oysters were collected monthly from seafood markets between September 2015 and...
Vegetation net primary productivity (NPP) has a great impact on terrestrial carbon cycle, which is an important index to determine the size of vegetation productivity and regulate ecological processes. In this paper, the urban with high spatial heterogeneity was selected as the research background, and the urban vegetation of Xuzhou was selected as the research object, then Landsat remote sensing...
The study of species habitat selection mechanism and spatial distribution prediction has important guiding significance for the conservation and maintenance of endangered species. In this study, the “3S” technology was used to obtain the ground survey data and ecological driving factors. Then the differences and correlations among the ecological driving factors were analyzed. The binary logistic regression...
Substance P (SP) is well known for its immunoregulatory influence on NK cells. The biological actions of SP are mediated primarily through the high-affinity neurokinin-1 receptor (NK-1R), a G protein-coupled receptor (GPCR). Receptor binding triggers a cAMP signaling pathway and intracellular levels of cAMP are regulated via Gαs and Gαi. In this study NF449, a Gαs-selective G protein antagonist, was...
Germination of platanus acerifolia's winter buds and cones falling bring great inconvenience to people's lives, therefore, how to reduce it becomes an issue of concern. Now studies on platanus acerifolia are mostly from phenotypic variation and follow-up observations which had difficulty in guaranteeing long-term stability, but less at the molecular level. This experiment use young leaves of fine...
In order to solve the problems of the communication among various metering devices in the traditional wireless meter reading system, Smart Message Language (SML) which is the definition of the German national standard for Automatic Meter Reading System is introduced. In this paper, the Wireless Meter Reading system is developed based on WI-FI, with the monitoring terminal of the hardware platform...
In current trusted network connection (TNC) model, access decisions are generally made at the time of request but typically do not recognize ongoing controls for relative continuous access or for immediate revocation. We propose a new model named trusted network connection based on usage control (U-TNC), which combine TNC solutions with usage control (UCON) to achieve pre-authorization and ongoing-authorization...
