BACKGROUND Dynamic interspinous spacers, such as X-stop, Coflex, DIAM, and Aperius, are widely used for the treatment of lumbar spinal stenosis. However, controversy remains as to whether dynamic interspinous spacer use is superior to traditional decompressive surgery.

Many studies have reported micro RNAs involved in the differentiation of bone marrow mesenchymal stem cells (BMSCs) into neural cells; however, the roles of long non-coding RNAs (lncRNAs) in the differentiation of BMSCs into neural cells remain poorly understood. We used microarray assays to compare the lncRNA and messenger RNA (mRNA) expression profiles in(More)
OBJECTIVE The aim of this study was to evaluate the efficacy and safety of anterior cervical corpectomy and fusion (ACCF) and anterior cervical discectomy and fusion (ACDF) for treating two-adjacent-level cervical spondylosis myelopathy (CSM). DESIGN A meta-analysis of the two anterior fusion methods was conducted. The electronic databases of PubMed, the(More)
In the title compound, [Zn(4)(C(16)H(10)N(4)O(2))(4)]·4H(2)O, the N'-[(8-oxidoquinolin-7-yl)methyl-idene]isonicotinohydrazidate (L(2-)) ligand binds to the metal ions, forming stable five- and six-membered chelate rings, leaving the pyridyl groups free. The compound is a tetra-nuclear Zn(II) complex centered about a fourfold roto-inversion axis, with the(More)

The paper is about the characteristics of the factual depletion layer in MOSFETs. The aim is to analyze the influences of the relative factors for depletion layer. The results indicate that the relative factors, such as, the thickness of gate dioxide, the bias voltage, the doping concentration, are related to the depletion layer thickness in MOSFETs. The(More)
