BACKGROUND Advanced oxidation protein products (AOPPs) are acknowledged as a novel marker of oxidation-mediated protein damage. This study aimed to investigate the plasma levels of AOPPs in postmenopausal osteoporotic women, and to determine the relationship between AOPPs accumulation and lumbar bone mineral destiny (BMD) or bone turnover markers.

Pro-inflammatory cytokine-induced chondrocyte apoptosis is a primary cause of cartilage destruction in the progression of rheumatoid arthritis (RA). Advanced oxidation protein products (AOPPs), a novel pro-inflammatory mediator, have been confirmed to accumulate in patients with RA. However, the effect of AOPPs accumulation on chondrocyte apoptosis and the(More)
Percutaneous vertebroplasty (PVP) is a common procedure in spine surgery. Bone cement leakage is the most common complication related to this procedure. The purpose of this study was to assess the incidence and risk factors for cement leakage after PVP. A total of 485 patients who underwent PVP between August 2003 and August 2013 were enrolled in the study.(More)
Ossification of the ligamentum flavum (OLF) is a rare disease that causes acquired thoracic spinal canal stenosis and thoracic myelopathy. The aim of this study was to investigate clinical outcomes of symptomatic thoracic OLF treated using posterior decompressive laminectomy. We retrospectively analyzed the medical records of 22 patients who underwent(More)
Terahertz Time-Domain Spectroscopy (THz-TDS) technique has a wide range of applications in substances identification and quantitative analysis. In the present paper, we report absorption spectra and index of refraction of 14 kinds of pure cephalosporins in 0.2-2.6 THz, in which eight kinds have apparent absorption peaks, while the others have different(More)
We have found a perpendicular magnetic anisotropy of iron adatoms on a surface of the prototypical three-dimensional topological insulator Bi2Se3 by using x-ray magnetic circular dichroism measurements. The orbital magnetic moment of Fe is strongly enhanced at lower coverage, where angle-resolved photoemission spectroscopy shows coexistence of non-trivial(More)
