On the Poisson's Ratio of the Nucleus Pulposus
Journal of Biomechanical Engineering, 2013Existing 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.

Viscoelastic properties of nucleus pulposus
Journal of Back and Musculoskeletal Rehabilitation, 1997Although 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].

Inflammatogenic Properties of Nucleus Pulposus
Spine, 1995The inflammatogenic properties of nucleus pulposus were assessed in two experimental models previously used for screening of inflammatogenic properties of other substances. This study was performed to assess the inflammatogenic properties of nucleus pulposus in models previously screened for other substances.Previous experimental studies, as well as ...

Enzyme Dissolution of the Nucleus Pulposus
Nature, 1963THOMAS 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.

Notochord to Nucleus Pulposus Transition
Current Osteoporosis Reports, 2015A tissue that commonly deteriorates in older vertebrates is the intervertebral disc, which is located between the vertebrae. Age-related changes in the intervertebral discs are thought to cause most cases of back pain. Back pain affects more than half of people over the age of 65, and the treatment of back pain costs 50-100 billion dollars per year in ...

Spine, 2011
Both sequestrated nucleus pulposus (SNP) and the remaining nucleus pulposus (RNP) were studied from the discs of the same patient to evaluate apoptosis using immunohistochemical staining.To compare apoptosis of the SNP and the RNP in the disc of the same patient.Many studies have been conducted on the natural history and apoptosis of the herniated ...

HERNIATION OF THE NUCLEUS PULPOSUS
The Journal of Nervous and Mental Disease, 1945In 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.

Hernia of the Nucleus Pulposus
The British Journal of Radiology, 1934In the radiological examination of the spine one frequently sees in association with kyphoses very varied contours of the upper and lower vertebral margins. They may appear wavy or show irregular sclerotic patches or even appear notched. These irregularities are apt to be dismissed, the mild ones as variations of the normal and the more gross ones ...
