Usefulness of multiecho fast field echo MRI in the evaluation of ossification of the posterior longitudinal ligament and dural ossification of the cervical spine. [PDF]

PLoS ONE, 2017
The diagnosis of ossification of the posterior longitudinal ligament (OPLL) on magnetic resonance imaging (MRI) is challenging. The purpose of this study is to evaluate the usefulness of the multiecho fast field echo (mFFE) MRI in the detection of ...

Nonlinear Modeling and Transient Stability Analysis of SG–PV Infeed Systems

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
The system stability can be judged by comparing the TEF value with the critical energy at the initial state of early fault recovery, no necessary to wait until late fault recovery. This study provides a system‐level physical picture and a fast transient stability criterion for the transient stability analysis of SG‐PV infeed systems.

Effect of teriparatide on ligamentum flavum mesenchymal stem cells isolated from patients with ossification of the posterior longitudinal ligament

Journal of Pharmacological Sciences, 2021
Ossification of the posterior longitudinal ligament (OPLL) within the spinal canal sometimes leads to severe myelopathy. Teriparatide (TPD) is a recombinant human parathyroid hormone (PTH) (1–34), which promotes osteogenesis of mesenchymal stem cells ...

Risk Factors of Cage Subsidence in Patients with Ossification of Posterior Longitudinal Ligament (OPLL) After Anterior Cervical Discectomy and Fusion

Medical Science Monitor, 2018
Background There are numerous reports on cage subsidence after ACDF; however, few studies have identified its risk factors. The current study aimed to identify risk factors for cage subsidence after ACDF using the PEEK cage packed with local autobone ...

“White Cord Syndrome”: A Reperfusion Injury Following Laminectomy and Spinal Decompression Surgery—A Case Report and Literature Review

Case Reports in Medicine, Volume 2026, Issue 1, 2026.
White cord syndrome (WCS) is a rare but serious postoperative complication characterized by new neurological deficits and hyperintense signal changes on T2‐weighted magnetic resonance imaging (MRI) following spinal decompression surgery. Since it was first described by Chin et al.

Segmental motion at the peak of the ossification foci is independent risk factor except for mal-alignment and thick ossification foci for poor outcome after laminoplasty for cervical ossification of the posterior longitudinal ligament: analyses in patients with positive K-line, lordotic alignment, and lower canal occupying ratio

Journal of Orthopaedic Surgery and Research, 2020
Purpose To elucidate the independent preoperative factors that have a significant impact on poor surgical outcome after laminoplasty for K-line (+) ossification of the posterior longitudinal ligament (OPLL).

Clinical Effectiveness of Posterior Cervical Decompression and Fusion in Terms of Reducing OPLL Growth Versus Cervical Motion Preservation

Neurospine, 2019
Spinal ossification of the posterior longitudinal ligament (OPLL) is a serious disorder that causes vertebral ligament calcification and gradual growth, resulting in spinal stenosis and, in severe cases, nerve paralysis due to spinal cord compression. If

MMC HVDC Controls for Damping Subsynchronous Interactions With LCC HVDC and Thermal Generator

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
This paper develops a subsynchronous damping controller (SSDC) on modular multilevel converter (MMC) HVDC with the aim of mitigating three‐way torsional interactions between a line commutated converter (LCC) HVDC, MMC HVDC and a nuclear generator. The test case is based on the French IFA2000 2 GW LCC HVDC and the new 1 GW MMC Eleclink, interacting with
