The distribution of several pathogenic helminth infections coincides geographically with many devastating microbial diseases, including enteric bacterial infections. To dissect the mechanisms by which helminths modulate the host's response to enteric bacteria and bacteria-mediated intestinal inflammation, we have recently established a coinfection model and(More)
BACKGROUND Abnormal expression of the liver peptide hormone hepcidin, a key regulator of iron homeostasis, contributes to the pathogenesis of anemia in conditions such as inflammatory bowel disease (IBD). Since little is known about the mechanisms that control hepcidin expression during states of intestinal inflammation, we sought to shed light on this(More)
Considering the rapid growth of China's elderly rural population, establishing both an adequate and a financially sustainable rural pension system is a major challenge. Focusing on financial sustainability, this article defines this concept of financial sustainability before constructing sound actuarial models for China's rural pension system. Based on(More)
The myristoylated capsid precursor mP1-2A of foot-and-mouth disease virus (FMDV), when expressed in mammalian cells and processed by the FMDV 3C protease, can self-assemble into virus-like particles (VLPs). In the present study, nine amino acids of the 3C protease were replaced by site-directed mutagenesis to create a mutant 3C protease, 9m3C. To coexpress(More)

This communication deals with the key issues of a hybrid actuation system operating in active/no-load mode. The hybrid actuation system under study is made of a servo valve controlled hydraulic actuator (SHA) and an electro-mechanical actuator (EMA). In active/no-load mode, both actuators are actively controlled; the SHA is in position control while the EMA(More)
Work-related injury insurance system which consists of work-related injury prevention system, work-related injury compensation system, work-related injury rehabilitation system is a complex social and systematic project. Firstly, the paper analyses the relations among the three subsystems, makes some basic hypotheses. Secondly, it sets up differential(More)
