BACKGROUND The balance between vasodilation and vasoconstriction plays a major role in maintaining vascular homeostasis. However, the underlying mechanisms are unclear. More and more evidence suggested that there was an interaction in the regulation of vasorelaxation between nitric oxide (NO) and hydrogen sulfide (H(2)S). We explored the interaction between(More)
In this paper, a real-time vehicle behavior analysis system is presented, which can be used in traffic jams and under complex weather conditions. In recent years, many works based on background estimation and foreground extraction for traffic event detection have been reported. In these studies, the vehicle images need to be accurately segmented, although(More)
OBJECTIVE To determine the psychometric properties and applicability of four pain scales in Chinese postoperative adults. DESIGN A prospective clinical study. SETTING A university-affiliated hospital. PATIENTS In total, 173 Chinese patients (age range 18-78 years) undergoing scheduled surgery. INTERVENTIONS Recalled pain and anticipated(More)
Hypoxic pulmonary hypertension is a pathophysiological process important in the development of various cardiopulmonary diseases. Recently, we found that sulfur dioxide could be produced endogenously by pulmonary vessels, and that it showed vascular regulatory capabilities. In this paper, we examined the role of sulfur dioxide in hypoxic pulmonary vascular(More)
Japanese encephalitis (JE) is a serious infectious disease in southern and eastern Asia. Design and development of safer and more efficacious vaccines against Japanese encephalitis virus (JEV) is a high-priority target in the world. Dendritic cells (DCs) are the most potent professional antigen-presenting cells (APCs) playing a central and unique role in(More)
RATIONALE Although the phosphodiesterase type 5 inhibitors sildenafil and tadalafil have demonstrated efficacy in patients with pulmonary arterial hypertension (PAH), monotherapy with these agents has not been conclusively shown to reduce clinical worsening events. OBJECTIVES To evaluate the safety and efficacy of the phosphodiesterase type 5 inhibitor(More)
An attenuated Japanese encephalitis virus (JEV) strain SA14-14-2, generated from the wild strain SA14, is an effective live vaccine against JEV infection. It has led to a significant decrease in JEV infection around the world. Although it is highly effective, the mechanism for its robust immunity was not well investigated. In this study, the interaction of(More)
UNLABELLED Dendritic cells (DCs) are the most efficient antigen-presenting cells, playing a key role in the adaptive immune responses to viral infections. Our studies demonstrate that wild-type (wt) rabies virus (RABV) does not activate DCs. Adoptive transfer of DCs primed with wt RABV did not activate DCs, stimulate virus neutralizing antibodies (VNA), or(More)
The blunt snout bream, Megalobrama amblycephala, is a herbivorous freshwater fish species native to China and a major aquaculture species in Chinese freshwater polyculture systems. In recent years, the bacterium Aeromonas hydrophila has been reported to be its pathogen causing great losses of farmed fish. To understand the immune response of the blunt snout(More)
Japanese encephalitis (JE) is caused by the Japanese encephalitis virus (JEV). It is a major public health problem in Asia. JEV infects swine which results in fatal encephalitis, abortion and stillbirth in pregnant sow, and hypospermia in boars. Swine is a viral amplifier, and thus plays a critical role in JEV transmission. Thus, development of a rapid(More)
