In Vitro Engineering of High Modulus Cartilage-Like Constructs
To date, the outcomes of cartilage repair have been inconsistent and have frequently yielded mechanically inferior fibrocartilage, thereby increasing the chances of damage recurrence. Implantation of constructs with biochemical composition and mechanical properties comparable to natural cartilage could be advantageous for long-term repair. This study attempted to create such constructs, in vitr...
متن کاملModulus Stabilization with Bulk Fields
We propose a mechanism for stabilizing the size of the extra dimension in the Randall-Sundrum scenario. The potential for the modulus field that sets the size of the fifth dimension is generated by a bulk scalar with quartic interactions localized on the two 3-branes. The minimum of this potential yields a compactification scale that solves the hierarchy problem without fine tuning of parameter...
متن کاملComparative study of the intrinsic mechanical properties of the human acetabular and femoral head cartilage.
Biphasic creep indentation methodology and an automated indentation apparatus were used to measure the aggregate modulus, Poisson's ratio, permeability, thickness, creep and recovery equilibrium times, and percentage of recovery of normal articular cartilage in 10 human hip joints. These properties were mapped regionally to examine the mechanical factors involved in the development of site-spec...
متن کاملCartilage Nominal Strain Correlates with Gag Content and Shear Modulus in Meniscectomized Joints
* **Song, Y, **Greve, J, **Gold, GE, * **Carter, DR, * **Giori, NJ * Bone and Joint Center, VA Palo Alto Health Care System, Palo Alto, CA [email protected] INTRODUCTION Meniscectomy leads to osteoarthritis (OA) in both human and animal knee joints. Spatial changes in biochemical composition and biomechanical properties over the entire surface of articular cartilage following meniscectomy h...
متن کاملRunning Modulus Recursions
Fix integers b ≥ 2 and k ≥ 1. Define the sequence {zn} recursively by taking z0 to be any integer, and for n ≥ 1, take zn to be the least nonnegative residue of bzn−1 modulo (n + k). Since the modulus increases by 1 when stepping from one term to the next, such a definition will be called a running modulus recursion or rumor for short. While the terms of such sequences appear to bounce around i...
