This study investigates therapeutic efficacy of photothermal therapy (PTT) in an orthotropic xenograft model of bone metastasis of breast cancer. The near-infrared (NIR) irradiation on Multi-Walled Carbon Nanotubes (MWNTs) resulted in a rapid heat generation which increased with the MWNTs concentration up to 100 μg/ml. MWNTs alone exhibited no toxicity, but(More)
BACKGROUND CC-chemokine receptor 7 (CCR7), which plays an important role in cell directional movement, is highly expressed in various cancers and positively related to lymph node metastasis. The inflammatory cytokine tumour necrosis factor (TNF)-α promotes tumour progression and lymph node metastasis in gallbladder cancer (GBC). However, the expression of(More)
Advanced oxidation protein products (AOPPs) have been shown to participate in the progression of rheumatoid arthritis (RA). However, the effect of AOPPs accumulation on catabolic effect in human chondrocyte and the underlying mechanism(s) remain unclear. The present study demonstrated that AOPPs inhibited cell viability and glycosaminoglycan (GAG)(More)
Topological insulators (TIs) are a new quantum state of matter. Their surfaces and interfaces act as a topological boundary to generate massless Dirac fermions with spin-helical textures. Investigation of fermion dynamics near the Dirac point (DP) is crucial for the future development of spintronic devices incorporating topological insulators. However,(More)
Oxidative stress is a possible pathogenesis of hyperalgesia. Advanced oxidation protein products (AOPPs), a new family of oxidized protein compounds, have been considered as a novel marker of oxidative stress. However, the role of AOPPs in the mechanism of hyperalgesia remains unknown. Our study aims to investigate whether AOPPs have an effect on(More)
Advanced oxidation production products (AOPPs) have been confirmed to accumulate in patients with rheumatoid arthritis (RA). Previous study demonstrated that AOPPs could accelerate cartilage destruction in rabbit arthritis model. However, the effect of AOPP stimulation on apoptosis of human chondrocyte and the underlying mechanisms remains unclear. This(More)
This study aimed to investigate the effect of AOPPs on apoptosis in human chondrocytes. Chondrocytes were treated with AOPPs. Cell death, nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity, reactive oxygen species (ROS) generation, and the expression of apoptotic proteins were detected in vitro. AOPPs levels were detected by colorimetric(More)
Magnetically doped topological insulators, possessing an energy gap created at the Dirac point through time-reversal-symmetry breaking, are predicted to exhibit exotic phenomena including the quantized anomalous Hall effect and a dissipationless transport, which facilitate the development of low-power-consumption devices using electron spins. Although(More)
We have unravelled the electronic structure of a class of metamagnetic shape memory alloy Ni2Mn1+x In1-x by combining bulk-sensitive hard x-ray photoelectron spectroscopy and first-principles density-functional calculations. A sharp drop in the Ni 3d e(g) density of states forming a pseudogap in the martensitic phase transition (MPT) for x   =   0.36 has(More)
Gallbladder cancer (GBC) is the most common malignant tumor in the human biliary tract, but the lack of a marker for timely diagnosis leads to an extremely poor prognosis. In this study, we assessed CpG sites in the WIF-1 promoter using bisulfite sequencing PCR and methylation-specific PCR to detect methylation in gallbladder cancer and cholecystitis(More)
