Autophagy in spinal ligament fibroblasts: evidence and possible implications for ossification of the posterior longitudinal ligament

Journal of Orthopaedic Surgery and Research, 2020
Background The molecular mechanisms of ossification of the posterior longitudinal ligament (OPLL) remain to be elucidated. The aim of the present study was to investigate the autophagy of spinal ligament fibroblasts derived from patients with OPLL and to

Association of miR-146a, miR-149, miR-196a2, and miR-499 Polymorphisms with Ossification of the Posterior Longitudinal Ligament of the Cervical Spine. [PDF]

PLoS ONE, 2016
Ossification of the posterior longitudinal ligament (OPLL) of the spine is considered a multifactorial and polygenic disease. We aimed to investigate the association between four single nucleotide polymorphisms (SNPs) of pre-miRNAs [miR-146aC>G ...

A case of cervical OPLL and DISH mimicking stroke

Surgical Neurology International, 2022
Background: Ossification of the posterior longitudinal ligament (OPLL) is a progressive disorder that mostly involves the cervical spine. It is more prevalent in East Asian countries. Patients typically present with the gradual onset of myelopathy, while about 5% show rapid progression.

Study for the hereditary trait of OPLL

Orthopedics & Traumatology, 1984
Hereditary trait of OPLL was studied radiographycally in twenty-two patients suffering from this disorder in the cervical spine. This study included ninety-nine persons of twenty-two families. The familial incidence of OPLL was found in nine families of twelve persons.

National Trends and Risk Factors for Dysphagia After Anterior Cervical Discectomy and Fusion

The Laryngoscope, Volume 136, Issue 9, Page 3918-3931, September 2026.
From 2016 to 2023, inpatient anterior cervical discectomy and fusion (ACDF) volume declined 52.2% while postoperative dysphagia rates increased 11.4% annually. Analysis of 496,425 cases demonstrated that dysphagia risk varied markedly by surgical indication, with cervical diffuse idiopathic skeletal hyperostosis, cervical spine fracture, and ...

Characterization of human posterior longitudinal ligament ossification (OPLL).

, 2018
(A) Serum proteins downregulated in four OPLL patients vs. four healthy controls and (B) quantitative analysis of one of these proteins. In proteomics analysis, a specific peak of mass 10300 Da was decreased in OPLL patients compared to healthy subjects.

Experimental ARoF System Based on OPLL Mm-Wave Generation for Beyond 5G [PDF]

, 2021
We experimentally analyze the ARoF based on OPLL mm-Wave generation performance for 5G fronthaul. Remarkable performance improvements are achieved for all 5G NR numerologies and different OPLL configurations despite their inherently high phase noise ...
