A paradigm shift in immunology has been the recent discovery of regulatory T cells (T reg cells), of which CD4(+)Foxp3(+) cells are proven as essential to self-tolerance. Using transgenic B6.Foxp3(hCD2) mice to isolate and ablate Foxp3(+) T reg cells with an anti-hCD2 antibody, we show for the first time that CD4(+)Foxp3(+) cells are crucial for infectious(More)
In this paper, we propose an algorithm for estimating dense shape and motion of dynamic piecewise pla-nar scenes from region correspondences using factor-ization. Region correspondences are used since they are e asier to establish and more r eliable than either line or point correspondences. The image measurements required a r e the centroid and area for(More)
The aim of this study is to explore the apoptotic induction and cell cycle arrest function of luteolin on the liver cancer cells and the related mechanism. The liver cancer cell line SMMC-7721, BEL-7402, and normal liver cells HL-7702 were treated with different concentrations of luteolin. Cell proliferation ability was tested. Morphological changes of the(More)

Lip reading has been proven to improve speech recognition accuracy in adverse environments. Most existing lip reading systems have frontal pose assumption, which makes it very difficult to use in tasks such as video transcription (speech recognition of the audio stream for video indexing and retrieval). In this paper, we propose a new method to compensate(More)
AbstrAct Renal ischemia-reperfusion (rI/R) could cause remote acute lung injury (ALI) and combination of these two organ injuries can remarkably increase the mortality. This study aims to determine whether dexmedetomidine, an α 2-adrenoreceptor agonist sedative, can ameliorate pulmonary microvascular hyper-permeability following rI/R injury and explore the(More)
BACKGROUND Chronic hepatitis C virus (HCV) infection leads to life-threatening complications worldwide. Immunomodulation signals the response to virus clearance. The immune-suppressive molecule human leukocyte antigen-G (HLA-G) has been shown to function in inhibiting both innate and adaptive immune responses. The objective of this study was to investigate(More)
