BACKGROUND China is facing a significant tuberculosis epidemic among rural-to-urban migrants, which poses a threat to TB control. This study aimed to understand the health seeking behaviour of and health systems responses to migrants and permanent urban residents suffering from chronic cough, in order to identify the factors influencing delays for both(More)
Rab3 and synaptotagmin have been reported to be the key proteins that have opposite actions but cooperatively play critical regulatory roles in selecting and limiting the number of vesicles released at central synapses. However, the exact mechanism has not been fully understood. In this study, Rab3A and synaptotagmin I, the most abundant isoforms of Rab3(More)
BACKGROUND Duck is an economically important poultry and animal model for human viral hepatitis B. However, the molecular mechanisms underlying host-virus interaction remain unclear because of limited information on the duck genome. This study aims to characterize the duck normal liver transcriptome and to identify the differentially expressed transcripts(More)
This review paper summarizes the recent research progress in the underlying mechanisms behind the shape memory effect (SME) and some newly discovered shape memory phenomena in polymeric materials. It is revealed that most polymeric materials, if not all, intrinsically have the thermo/chemo-responsive SME. It is demonstrated that a good understanding of the(More)
The selection of stably expressed reference genes is a prerequisite when evaluating gene expression, via real-time PCR, in cells in response to viral infections. The objective of our study was to identify suitable reference genes for mRNA expression analysis in chicken embryonic fibroblasts (CEF) after infection with avian leukosis virus subgroup J (ALV-J).(More)
We provide new analyses of Lloyd's algorithm (1982), commonly known as the k-means clustering algorithm. Kumar and Kannan (2010) showed that running k-SVD followed by a constant approximation k-means algorithm , and then Lloyd's algorithm, will correctly cluster nearly all of the dataset with respect to the optimal clustering, provided the dataset satisfies(More)
Staphylococcus aureus is a major foodborne pathogen. The primary purpose of this research was to evaluate S. aureus contamination levels and distribution characteristics in various kinds of food. A total of 121 samples of 11 kinds of food were collected from different food markets in the summer season according to their availability and popularity, and 103(More)
The local intestinal mucosa, the largest mucosal immune system in animals, plays an important role in resistance against intestinal pathogen infection. However, the molecular antiviral mechanisms of the intestinal mucosa remain poorly understood. In this study, we screened and identified differentially expressed transcripts in (PSV) porcine intestinal(More)
