Mechanical strain plays a critical role in the proliferation, differentiation and maturation of bone cells. As mechanical receptor cells, osteoblasts perceive and respond to stress force, such as those associated with compression, strain and shear stress. However, the underlying molecular mechanisms of this process remain unclear. Using a four-point bending(More)
A20 gene functions in negative immunoregulation and its SNP is related to SLE disease. But its expression level in immune cells from SLE patients is still unclear. The aim of this study is to investigate whether the expression of A20 is associated with pathogenesis of SLE. Real-time transcription-polymerase chain reaction analysis (RT-PCR) was used to(More)
Intrusion detection systems based on a hybrid approach have attracted considerable interest from researchers. Hybrid classifiers are able to provide improved detection accuracy, but usually have a complex structure and high computational costs. In this research, we propose a new and easy-to-implement hybrid learning method, named distance sum-based support(More)
Programmed cell death 4 (PDCD4) is a newly described tumour suppressor that inhibits oncogenesis by suppressing gene transcription and translation. Loss of PDCD4 expression has been found in several types of human cancers including the most common cancer of the brain, the gliomas. However, the molecular mechanisms responsible for PDCD4 gene silencing in(More)
To develop an effective therapeutic strategy for cardiac regeneration using bone marrow mesenchymal stem cells (BM-MSCs), the primary mouse BM-MSCs (1(st) BM-MSCs) and 5(th) passage BM-MSCs from β-galactosidase transgenic mice were respectively intramyocardially transplanted into the acute myocardial infarction (AMI) model of wild type mice. At the 6(th)(More)
Tumor invasion and metastasis are the major reasons for leading death of patients with hepatocellular carcinoma (HCC). Therefore, to identify molecules that can suppress invasion and metastasis of tumor will provide novel targets for HCC therapies. Tumor necrosis factor (TNF)-alpha-induced protein 8-like 2, TIPE2, is a novel immune negative molecule and an(More)
Programmed cell death-4 (PDCD4), a selective protein translation inhibitor, has shown proinflammatory effect in some inflammatory diseases, but its roles in obesity remain unestablished. This study aims to investigate the effects of PDCD4 on obesity, inflammation, and insulin resistance. Surprisingly, high-fat diet (HFD)-fed PDCD4-deficient (PDCD4(-/-))(More)
Interleukin (IL)-35 is a newly identified immune negative molecule which is secreted by CD4(+)Foxp3(+) T regulatory cells (Tregs) and contributes to their suppressive capacity. Early data have shown that IL-35 inhibits development of several autoimmune diseases. However, the role of IL-35 in atherosclerosis, a lipid-driven chronic inflammatory disease in(More)
Transparent conductive current-spreading layer is important for quantum efficiency and thermal performance of light-emitting diodes (LEDs). The increasing demand for tin-doped indium oxide (ITO) caused the price to greatly increase. Super-aligned carbon nanotubes (SACNTs) and Au-coated SACNTs as current-spreading layer were applied on AlGaInP LEDs. The LEDs(More)
Because of their feasibility and effectiveness, artificial intelligence-based intrusion detection systems attract considerable interest from researchers. However, when confronted with large-scale data sets, many artificial intelligence-based intrusion detection systems could suffer from a high computational burden, even though the feature selection method(More)
