In this paper, a new method of human detection based on depth map from 3D sensor Kinect is proposed. First, the pixel filtering and context filtering are employed to roughly repair defects on the depth map due to information inaccuracy captured by Kinect. Second, a dataset consisting of depth maps with various indoor human poses is constructed as benchmark.(More)
The effect of gold nanoparticles on lung cancer cells is not yet clear. In this study, we investigated the cytotoxicity and cell invasion activity of lung cancer cells after treatment with gold nanoparticles and showed that small gold nanoparticles can be endocytosed by lung cancer cells and that they facilitate cell invasion. The growth of A549 cells was(More)
We have successfully developed Fengshi Xiandan ([symbol: see text]) and used it to treat 53 cases of rheumatoid arthritis (RA), with indomethacin used to treat another 53 cases of RA as the controls. The results showed that the rate of cure and obvious effect was 54.7% and the total effective rate was 92.4% in the treatment group, as compared to 26.4% and(More)
Transforming growth factor-β (TGF-β) is a pleiotropic cytokine that controls an immense number of cellular responses and plays a prominent role in maintaining homeostasis of most human organs. In the intestine, the TGF-β is involved in mucosal defense, immune tolerance, inhibition of acute inflammation, promoting the wound-healing process, and suppressing(More)
Ischemic stroke is a leading cause of death and disability, and the treatment options are limited. Recent studies demonstrated that the promising applications of gold nanoparticles (Au-NPs) as intrinsic therapeutics; however, little is known about the effect of Au-NPs on cerebral ischemia-reperfusion (I/R) injury. In this paper, the role of Au-NPs on(More)
Tight junction dysfunction plays a vital role in some chronic inflammatory diseases. Pro-inflammatory cytokines, especially tumor necrosis factor alpha (TNF-α), act as important factors in intestinal epithelial tight junction dysfunction during inflammatory conditions. Autophagy has also been shown to be crucial in tight junction function and claudin-2(More)
Inflammatory bowel diseases (IBDs) are chronic, inflammatory disorders of the gastrointestinal tract with unclear etiologies. Intestinal epithelial cells (IECs), containing crypt and villus enterocytes, occupy a critical position in the pathogenesis of IBDs and are a major producer of immunoregulatory cytokines and a key component of the intact epithelial(More)
An improved face detection and recognition method based on information of skin color and depth obtained by binocular vision system was proposed in this paper. With this method, the face area was detected firstly by using Adaboost algorithm. Afterwards, the real face was distinguished from fake one by using the skin color information and the depth data.(More)
