Reversible acetylation of alpha-tubulin has been implicated in regulating microtubule stability and function. The distribution of acetylated alpha-tubulin is tightly controlled and stereotypic. Acetylated alpha-tubulin is most abundant in stable microtubules but is absent from dynamic cellular structures such as neuronal growth cones and the leading edges(More)
The efficient clearance of cytotoxic misfolded protein aggregates is critical for cell survival. Misfolded protein aggregates are transported and removed from the cytoplasm by dynein motors via the microtubule network to a novel organelle termed the aggresome where they are processed. However, the means by which dynein motors recognize misfolded protein(More)
OBJECT The authors report the long-term (more than 10-year) results of cervical laminoplasty for ossification of the posterior longitudinal ligament (OPLL) of the cervical spine as well as the factors affecting long-term postoperative course. METHODS The authors reviewed data obtained in 92 patients who underwent cervical laminoplasty between 1982 and(More)
Acetylation is mediated by acetyltransferases and deacetylases, and occurs not only on histones but also on diverse proteins. Although histone acetylation in chromatin structure and transcription has been well studied, the biological roles of non-histone acetylation remain elusive. Histone deacetylase 6 (Hdac6), a member of the histone deacetylase (HDAC)(More)
OBJECT Osteoporotic vertebral fractures occasionally lead to late-onset collapse, kyphosis, persistent back pain, and disability. The authors describe a series of patients in whom they performed percutaneous vertebroplasty by using calcium phosphate cement (CPC) to obtain early pain relief and improve the integrity of the osteoporotic vertebral body (VB).(More)
OBJECT Few studies have been conducted to compare vertebroplasty and conservative treatment for osteoporotic vertebral compression fractures (OVCFs). To investigate the effects of calcium phosphate cement (CPC)-based vertebroplasty on relief of pain and augmentation of the fractured vertebral body (VB), the authors compared the results of CPC-assisted(More)
INTRODUCTION The etiology of degenerative disc disease is unknown. Several investigators have reported the presence of proteolytic enzymes, such as the matrix metalloproteinase (MMP) and ADAMTS (a disintegrin and metalloprotease with thrombospondin-like repeats) families, in degenerated human discs. Glasson and colleagues recently reported that a(More)
OBJECT The purpose of this study was to analyze the risk factors for leakage of calcium phosphate cement (CPC) after vertebroplasty for osteoporotic vertebral fractures and to determine whether the vertebral body (VB) leakage caused any changes in the therapeutic benefits. METHODS Between August 2000 and April 2002, the authors performed 65 CPC-assisted(More)
Study Design A multinational, multiethnic, cross-sectional image-based study was performed in 33 institutions, representing 10 countries, which were part of the AOSpine Asia Pacific Research Collaboration Consortium. Objective Lumbar facet joint orientation has been reported to be associated with the development of degenerative spondylolisthesis (DS). The(More)
