Circadian Clock Regulation via Biomaterials for Nucleus Pulposus

Advances in Materials, 2023
Circadian clock disorder during tissue degeneration has been considered the potential pathogenesis for various chronic diseases, such as intervertebral disc degeneration (IVDD).

Intervertebral disc human nucleus pulposus cells associated with back pain trigger neurite outgrowth in vitro and pain behaviors in rats

Science Translational Medicine, 2023
Low back pain (LBP) is often associated with the degeneration of human intervertebral discs (IVDs). However, the pain-inducing mechanism in degenerating discs remains to be elucidated.

SIRT1 alleviates IL-1β induced nucleus pulposus cells pyroptosis via mitophagy in intervertebral disc degeneration.

International Immunopharmacology, 2022
Inflammatory stress of nucleus pulposus cells (NPCs) plays an important role in the pathogenesis of intervertebral disc degeneration (IVDD). Pyroptosis and NLRP3 inflammasome activation have been reported aggravating IVDD.

On the Poisson's Ratio of the Nucleus Pulposus

Journal of Biomechanical Engineering, 2013
Existing experimental data on the Poisson's ratio of nucleus pulposus (NP) tissue is limited. This study aims to determine whether the Poisson's ratio of NP tissue is strain-dependent, strain-rate-dependent, or varies with axial location in the disk.

Combined nucleus pulposus augmentation and annulus fibrosus repair prevents acute intervertebral disc degeneration after discectomy

Science Translational Medicine, 2020
Tissue-engineered therapies targeting the nucleus pulposus and annulus fibrosus prevent intervertebral disc degeneration after discectomy in sheep. Strategic lumbar support Discectomy is a common treatment for herniated or “slipped” intervertebral discs ...

HERNIATION OF THE NUCLEUS PULPOSUS

The Journal of Nervous and Mental Disease, 1945
In this study of 100 cases in which a herniated nucleus pulposus was removed, all patients had sciatic pain, and, with one exception, all had back pain, preceding or coincident with the sciatica. Roentgenographic or clinical examination revealed an unstable lumbosacral joint in eighty-four cases.

Viscoelastic properties of nucleus pulposus

Journal of Back and Musculoskeletal Rehabilitation, 1997
Although there have been many studies on the mechanical properties of the annulus fibrosus [1], the fibrous outer layers of the intervertebral disc, there have been fewer studies published on the mechanical properties of its soft centre, the nucleus pulposus [2-4].

Enzyme Dissolution of the Nucleus Pulposus

Nature, 1963
THOMAS showed the surprising susceptibility of cartilage to the action of papain when he produced collapse of the ears of young rabbits by injecting the enzyme intravenously1,2. All cartilaginous tissue of the body was affected; the epiphyseal cartilages appeared to be particularly sensitive.
