Recent advances in the development of new drugs to halt or even reverse the progression of Osteoarthritis at an early-stage requires new tools to detect early degeneration of articular cartilage. We investigated the ability of an electromechanical...Read More
Quantitative assessments of articular cartilage function are needed to aid clinical decision making. Our objectives were to develop a new electromechanical grade to assess quantitatively cartilage quality and test its reliability. Electromechanical properties were measured using a hand-held electromechanical probe on 200 human articular surfaces from cadaveric donors and osteoarthritic...Read More
OBJECTIVE:The hand-held ? device is used to map electromechanical properties of articular cartilage. The purpose of the study was to evaluate correlation of electromechanical properties with histological, biochemical and biomechanical...Read More
Objectives
Development of novel vocal fold (VF) therapeutics is limited by a lack of standardized, meaningful outcomes. We hypothesize that automated microindentation?based VF biomechanical property mapping matched to histology permits quantitative assessment.
Study Design
Ex vivo.
Methods
Twelve anesthetized New Zealand white rabbits underwent...Read More
Abstract: Designing protective systems for the human head—and, hence, the brain—requires understanding the brain’s microstructural response to mechanical insults. We present the behavior of wet and dry porcine brain undergoing quasi-static and high strain rate mechanical deformations to unravel the effect of hydration on the brain’s biomechanics. Here, native ‘wet’ brain samples...Read More
Purpose: Osteoarthritis (OA) is a debilitating chronicdisease. Currently, there is no cure or disease modifying treatment for OA.Using a Sprague-Dawley rat model, it has been shown that ahigh-fat/high-sucrose (HFS) diet induced obesity leads to histological OA-likechanges in the knee, and an infiltration of fat, collagen, and macrophages intoskeletal muscle within 12-weeks. Additionally,...Read More

We present an electrodeposition technique for fabricating tubular alginate structures. In this technique, two electrodes (anode and cathode) are suspended in a solution of alginate and insoluble calcium carbonate particles, and the application of an electrical potential produces a localized pH change at the anode surface causing suspended divalent cations to become soluble and cross-link the alginate....Read More
Objective
The objective of this study was to assess a novel 3D microstructured scaffold seeded with allogeneic chondrocytes (cells) in a rabbit osteochondral defect model.
Design
Direct laser writing lithography in pre-polymers was employed to fabricate custom silicon-zirconium containing hybridorganic-inorganic (HOI) polymer SZ2080 scaffolds of a predefined morphology....Read More
The cellular and molecular mechanisms underlying senile osteoporosisremain poorly understood. In this study, transgenic mCol1?1-Pitx1 miceoverexpressing paired-like homeodomain 1 (PITX1), a homeobox transcriptionfactor, rapidly develop a severe type-II osteoporotic phenotype withsignificant reduction in bone mass and biomechanical strength similar to thatseen in humans and reminiscent of the phenotype...Read More
Graphene oxide (GO) induced enhancement of elastomer properties showed a great deal of potential in recent years, but it is still limited by the barrier of the complicated synthesis processes. Stereolithography(SLA),used in fabrication of thermosets and very recently in “?exible” polymers with elastomeric properties, presents itself as simple and user-friendly method for integration of GO into...Read More
A mixture of polymers with lubricating properties is provided. The polymer can be used to produce a lubricating fluid. They can also be born on a surface or embedded in a porous material. This mixture of polymers comprises (a) a pharmaceutically acceptable bottle-brush polymer comprising a back bone with polymeric pendant chains, and (b) a pharmaceutically acceptable linear polymer. In the lubricating...Read More
Purpose:
Osteoarthritis (OA) is a joint disease characterized by cartilage degeneration and bone spur formation. Due to the fact that there are no disease modifying drugs, OA is placing a high burden on society occurring during diseases. By applying genetic analyses and functional follow up research, our group demonstrated that the upregulation of the type IIiodothyronine deiodinase...Read More
Bacteriophages are essentially bionanoparticles with a protein coat, the composition of which can be controlled with atomic precision via genetic engineering, a property that makes them superior to synthetic nanoparticles as building blocks for bottom-up synthesis of multifunctional materials with advanced properties. We report hierarchically structured hydrogels of self-organized M13 bacteriophage...Read More
Tissue-engineering research to date has neglected to address the annulus fibrosus (AF) cartilage endplate (CEP) interface of the intervertebral disc. It was hypothesized that in vitro formed outer AF and cartilage tissues will integrate inco-culture to form an interface containing ECM that resembles the native interface, and that can be mechanically and compositionally enhanced through dynamic loading....Read More
This thesis describes the effects of ionic solutions on biopolymer films and the development of a 3D printed personalized wound dressing.
Chitosan, gelatin, and composite chitosan/gelatin films were exposed to NaCl, Na2SO4, and CaCl2 solutions with varying ionic strength and their swelling and dissolution properties were measured. In addition, the release of the small ionic molecules Rhodamine...Read More
Arylsilicones are widely exploited for their thermal and optical properties. The creation of phenylsilicone elastomers with specific physical properties is typically done by a ‘one off’ formulation and test process. We demonstrate that high?throughput synthesis methods can be used to rapidly prepare a series of arylsilicone elastomers and then assess the relative impact of different aryl groups...Read More
This paper proposes a new numerical framework to simulate ultrasound wave propagation in 3D viscoelastic heterogeneous media based on the elastodynamic wave equation including a 3D second-order time-domain perfectly matched layer formulation. A finite difference discretization of this formulation is presented, along with a stability analysis. The resulting model is capable of simulating 3D shear...Read More
Noncanonical Wnt signaling in stem cells is essential to numerous developmental events. However, no prior studies have capitalized on the osteoinductive potential of noncanonical Wnt ligands to functionalize biomaterials in enhancing the osteogenesis and associated skeleton formation. Here, we investigated the efficacy of the functionalization of biomaterials with a synthetic Wnt5a mimetic ligand...Read More
