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.

Inflammatogenic Properties of Nucleus Pulposus

Spine, 1995
The 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 ...

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].

Notochord to Nucleus Pulposus Transition

Current Osteoporosis Reports, 2015
A 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 ...

Autologous nucleus pulposus primes T cells to develop into interleukin‐4‐producing effector cells: An experimental study on the autoimmune properties of nucleus pulposus

Journal of Orthopaedic Research, 2009
An autoimmune response to herniated nucleus pulposus has been proposed to constitute a pathophysiologic mechanism for inducing sciatica based on the fact that nucleus pulposus under normal conditions is excluded from the development of immunological ...

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.

Apoptosis in the Sequestrated Nucleus Pulposus Compared to the Remaining Nucleus Pulposus in the Same Patient

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 ...

Reflections on the Nucleus Pulposus

Rivista di Neuroradiologia, 1998
The intervertebral disc is usually divided into two parts, the anulus fibrosus and the nucleus pulposus. However, they are not considered two separate anatomic parts since one is essentially part of the other and this should be borne in mind to understand the process of ageing. The intervertebral disc should therefore be thought of as
