Mechanobiology of the Intervertebral Disc and Relevance to Disc Degeneration

Journal of Bone and Joint Surgery, 2006
Mechanical loading of the intervertebral disc may contribute to disc degeneration by initiating degeneration or by regulating cell-mediated remodeling events that occur in response to the mechanical stimuli of daily activity. This article is a review of the current knowledge of the role of mechanical stimuli in regulating intervertebral disc cellular ...

Janus Discs

Journal of the American Chemical Society, 2007
We describe the synthesis and the solution properties of sheet- and disclike Janus particles, containing an inner crosslinked polybutadiene (PB) layer and two different outer sides of polystyrene (PS) and poly(tert-butyl methacrylate) (PtBMA). The structures formed upon adsorption of the flat Janus particles onto solid substrates as well as in THF ...

Rewinding the DISC

Archivum Immunologiae et Therapiae Experimentalis, 2008
Fas (CD95/APO-1) belongs to the tumor necrosis factor receptor family and its signaling pathway has been extensively studied over the past 15 years. Blockade of the Fas-mediated apoptotic signal leads to abusive lymphoproliferation, auto-immunity, and an increased risk of developing lymphoma and leukemia.

The Rolling Disc

1996
In this paper we consider a homogeneous disc, which rolls without slipping on a horizontal plane under the influence of a vertical gravitational field. Due to the four dimensional symmetry group consisting of translations in the plane, rotations around a vertical axis and rotations around the axis perpendicular to the disc, one can reduce the dynamics ...

DANDY'S DISC

Neurosurgery, 2009
Much has been written about the accomplishments of Walter E. Dandy, and he remains one of the seminal figures in neurosurgery. He is perhaps best known for his scientific contributions to our understanding of cerebrospinal fluid and pituitary gland physiology and his clinical contributions of ventriculography, cerebellopontine angle approaches for a ...
