The present study dissected the role of a Th2 bias in pathogenesis of Cryptococcus neoformans H99 infection by comparing inhalational H99 infections in wild-type BALB/c and IL-4/IL-13 double knockout mice. H99-infected wild-type mice showed all major hallmarks of Th2 but not Th1/Th17 immunity in the lungs and lung-associated lymph nodes. In contrast, the(More)
This study was to investigate the prevalence of HEV in pig herds under different breeding environment and in abattoirs located in Beijing, China. In total 638 sera samples and 114 liver samples were collected for a serological survey and a RT-PCR assay, respectively. The average prevalence rate of HEV in pig herds in Beijing suburb were 47.5-100%.(More)
Due to the development of information technologies and network technologies, healthcare systems have been employed in many countries. As an important part of healthcare systems, the wireless body area network (WBAN) could bring convenience to both patients and physicians because it could help physicians to monitor patients’ physiological values remotely. It(More)
Artemisinin resistance in Plasmodium falciparum parasites in Southeast Asia is a major concern for malaria control. Its emergence at the China-Myanmar border, where there have been more than 3 decades of artemisinin use, has yet to be investigated. Here, we comprehensively evaluated the potential emergence of artemisinin resistance and antimalarial drug(More)
Changes in airway dynamics have been reported in the rat model of pulmonary cryptococcosis. However, it is not known if Cryptococcus neoformans-induced changes in lung functions are related to the immunophenotype that develops in response to cryptococcal infection in the lungs. In this study we performed a parallel analysis of the immunophenotype and airway(More)
BACKGROUND N-4-Tert-Butyl benzyl haloperidol chloride (C(3)) was a novel calcium antagonist synthesized in our laboratory. The present study is to explore the effect of C(3) on vascular smooth muscle cell proliferation and the mechanism involved. METHODS The effects of C(3) on Ang II-induced cytosolic free Ca(2+) concentration change, VSMC proliferation,(More)
The potential role of the mast cells in the invasion of very virulent infectious bursal disease virus (vvIBDV) is unknown. We evaluated mast cell activity and tryptase production after vvIBDV infection in special pathogen-free (SPF) chickens using cytochemistry and immunohistochemistry analyses. The results were as follows: (1) severe histologic lesions(More)
Liquefaction foundation treated by stone columns is analyzed by the fully coupled three-dimension effective-stress dynamic analysis procedure; the influence law of stone columns design parameter on anti-liquefaction effect is discussed. The research shows that with the diameter of stone columns increasing, the surface maximum horizontal vibration(More)
It has been found that microRNAs (miRNAs) can function as a regulatory factor across species. For example, food-derived plant miRNAs may pass through the gastrointestinal (GI) tract, enter into the plasma and serum of mammals, and interact with endogenous RNAs to regulate their expression. Although this new type of regulatory mechanism is not well(More)
