Hypoxia is a common characteristic of many pathological and physiological conditions that can markedly change cellular metabolism and cause the accumulation of extracellular adenosine. Recent studies have shown that adenosine can modulate the function of certain immune cell types through binding with different adenosine receptors. Our previous studies have(More)
Previous studies have demonstrated that the overexpression of Kif2a is involved in the progression, invasion and metastasis of squamous cell carcinoma of the oral tongue (SCCOT). Few studies have reported the correlation between Kif2a and apoptosis of tumor cells and which signaling pathways Kif2a is involved in remains unclear. The(More)
Robust face image modeling under uncontrolled conditions is crucial for the current face recognition systems in practice. One approach is to seek a compact representation of the given image set which encodes the intrinsic lower dimensional manifold of them. Among others, Local Linear Embedding (LLE) is one of the most popular method for that purpose.(More)
As a biomaterial, chitosan has been widely used in tissue engineering, wound healing, drug delivery, and other biomedical applications. It can be formulated in a variety of forms, such as powder, film, sphere, gel, and fiber. These features make chitosan an almost ideal biomaterial in cell culture applications, and cell cultures arguably constitute the most(More)
Fucoidan is a complex sulfated polysaccharide with a wide variety of biological activities for modulating immune cell functions. However, the effects of fucoidan on maturation process and activation of human monocyte-derived dendritic cells (DCs) remain to be elucidated. The present study demonstrated that the level of special marks and polarization(More)
Dihydroartemisinin (DHA), a semi-synthetic derivative and active metabolite of artemisinin, has been shown to have profound anticancer potential in addition to its strong anti-malarial activity. The purpose of the present study was to thoroughly investigate the anti-neoplastic effects induced by DHA and to provide(More)
Studies of maternal-fetal tolerance focus on defining mechanisms for establishment of immunological privilege within the uterus during pregnancy. Fetal trophoblasts play a key role in maternal tolerance, in part through cytokines production. As a novel inhibitory cytokine, IL-35 is produced by Foxp3(+) regulatory T cells (Tregs) and mediates maximal(More)
It is well recognized that tissue microenvironments are involved in regulating the development and function of dendritic cells (DC). Oxygen supply, which varies in different tissues, has been accepted as an important microenvironmental factor in regulating the biological functions of several immune cells and as being involved in tumour progression and(More)
Simple, accurate, and stable diagnostic tests are essential to control viral infectious diseases such as avian influenza virus. The current technologies are often inaccessible to people who need them, mainly because of the specialized equipment and the need for highly trained technologists. Here, we describe a rapid isothermal nucleic acid detection assay(More)
Tissue inhibitor of metalloproteinase-3 (TIMP-3) is one of a family of proteins inhibiting matrix metalloproteinases, which has also been identified as a mediator for checking inflammation. Meanwhile, it is well known that inflammation causes the activation of the immune response. However, it is not clear whether TIMP-3 plays a role in the immune system. In(More)
