OBJECT Cervical spondylosis that causes upper-extremity muscle atrophy without gait disturbance is called cervical spondylotic amyotrophy (CSA). The distal type of CSA is characterized by weakness of the hand muscles. In this retrospective analysis, the authors describe the clinical features of the distal type of CSA and evaluate the results of surgical(More)
STUDY DESIGN Retrospective clinical study. PURPOSE To investigate the outcomes after indirect posterior decompression and dekyphosis using multilevel Ponte osteotomies for ossification of the posterior longitudinal ligament (OPLL) of the thoracic spine. SUMMARY OF BACKGROUND DATA There are no previous reports on the use of Ponte osteotomy to treat(More)
Amyotrophic lateral sclerosis (ALS) is a motor neuron-specific neurodegenerative disease. An increasing body of evidence suggests that, in addition to cell autonomous regulation, i.e., pathological changes in motor neurons, non-cell autonomous mechanisms involving glial cells play critical roles in the pathogenesis of ALS. CD44 functions as a receptor for(More)
Biopolymers consist of three major classes, i.e., polynucleotides (DNA, RNA), polypeptides (proteins) and polysaccharides (sugar chains). It is widely accepted that polynucleotides and polypeptides play fundamental roles in the pathogenesis of neurodegenerative diseases. But, sugar chains have been poorly studied in this process, and their(More)
PURPOSE The purpose of this study was to describe the radiological outcomes in patients with unilateral instrumented fixation for cervical dumbbell tumors. PATIENTS AND METHODS Fourteen consecutive individuals were included in the present study. We included Eden type II and III tumors in this cohort study and analyzed fixed segment fusion rates, screw(More)
We have previously shown that DPF2 (requiem/REQ) functions as a linker protein between the SWI/SNF complex and RelB/p52 NF-κB heterodimer and plays important roles in NF-κB transactivation via its noncanonical pathway. Using sensitive 293FT reporter cell clones that had integrated a SWI/SNF-dependent NF-κB reporter gene, we find in this study that the(More)
The mammalian transcriptional factors, Cdx1 and Cdx2 (Cdx is caudal-type homeobox) are paralogues and critical for the cellular differentiation of intestinal or colorectal epithelia. It has been reported previously that in Cdx1 transgenic or knockout mice, endogenous Cdx2 levels are inversely correlated with Cdx1 levels. Recently, we found that exogenous(More)
In epithelial cells, miRNA-199a-5p/-3p and Brm, a catalytic subunit of the SWI/SNF complex were previously shown to form a double-negative feedback loop through EGR1, by which human cancer cell lines tend to fall into either of the steady states, types 1 [miR-199a(-)/Brm(+)/EGR1(-)] and 2 [miR-199a(+)/Brm (-)/EGR1(+)]. We show here, that type 2 cells,(More)
STUDY DESIGN A retrospective analysis of a prospective database. OBJECTIVE To compare preoperative symptoms, ambulatory ability, intraoperative spinal cord monitoring, and pathologic cell proliferation activity between intramedullary only and intramedullary plus extramedullary hemangioblastomas, with the goal of determining the optimal timing for surgery.(More)
The purposes of this study were to evaluate the clinical outcome after surgical treatment of patients with the proximal type of cervical spondylotic amyotrophy (CSA) and to explore the appropriate timing for surgical intervention. A retrospective review was performed on a consecutive cohort of 41 patients who underwent surgical treatment for the proximal(More)
