Limited proteolysis combined with mass spectrometry reveals that the compact core structural domain of OLF consists of approximately residues 238-461, which retains the single disulfide bond and is as stable as the full myoc-OLF construct.
In the ossification front of OLF, fiber bundles of the ligament showed disorganization of the elastic fibers and an abundance of collagen fibers.
The melting of MBP is deconvoluted from the melting of OLF by the addition of 50 mM maltose.
Our study showed significant matrix degeneration in the ossification front of OLF and the presence of several ossification fronts between the ossified plaque and non-ossified fiber area.
Figures 6(b), 6(c), 7(b), and 7(c) show the differences in the covariance networks of OLF between the groups of patients with PI and healthy controls.
In the cervical spine, the combination of ossification of the ligamentum flavum (OLF) and ossification of the posterior longitudinal ligament (OPLL) is rarely seen.
Dural laceration frequently occurs during surgery in patients with ossification of the ligamentum flavum (OLF), mainly because of dural adhesion (DA) and dural ossification (DO) between the ligamentum flavum and the dura mater.
We investigated the pH stability profile of myoc-OLF to elucidate any preferences of this domain as well as to gain insight into its resilience under different pH environments, such as low pH, that might be encountered under a known age-related TEM stressor, oxidative stress [21].
The 200 210 nm range is more positive at pH 4.6 than the others, suggestive of non-native features of OLF in this buffer environment, but otherwise there are only slight differences in the intensity of the two major minima at ∼217 and ∼230 nm (Figure 2A).
The mRNA expression levels of Sox9, Runx2, Msx2, and AP-1 in cultured cells from the ligamentum flavum of OLF patients were significantly different from those of the control.
