Physical non-viral gene delivery methods for tissue engineering
(Springer Verlag, 2013-03)The integration of gene therapy into tissue engineering to control differentiation and direct tissue formation is not a new concept; however, successful delivery of nucleic acids into primary cells, progenitor cells, and ... -
Enabling Surgical Placement of Hydrogels through Achieving Paste-Like Rheological Behavior in Hydrogel Precursor Solutions
(Springer Verlag, 2015-10)Hydrogels are a promising class of materials for tissue regeneration, but they lack the ability to be molded into a defect site by a surgeon because hydrogel precursors are liquid solutions that are prone to leaking during ... -
Swelling equilibrium of dentin adhesive polymers formed on the water-adhesive phase boundary: Experiments and micromechanical model
(Elsevier, 2014-01)During their application to the wet, oral environment, dentin adhesives can experience phase separation and composition change which can compromise the quality of the hybrid layer formed at the dentin-adhesive interface. ... -
Osteochondral Interface Tissue Engineering Using Macroscopic Gradients of Bioactive Signals
(Springer Verlag, 2010-04-09)Continuous gradients exist at osteochondral interfaces, which may be engineered by applying spatially patterned gradients of biological cues. In the present study, a protein-loaded microsphere-based scaffold fabrication ... -
Emerging Techniques in Stratified Designs and Continuous Gradients for Tissue Engineering of Interfaces
(Springer Verlag, 2010-04-22)Interfacial tissue engineering is an emerging branch of regenerative medicine, where engineers are faced with developing methods for the repair of one or many functional tissue systems simultaneously. Early and recent ... -
Multivariate Analysis of Attenuated Total Reflection Fourier Transform Infrared (ATR FT-IR) Spectroscopic Data to Confirm Phase Partitioning in Methacrylate-Based Dentin Adhesive
(SAGE Publications, 2014-05-16)Water is ubiquitous in the mouths of healthy individuals and is a major interfering factor in the development of a durable seal between the tooth and composite restoration. Water leads to the formation of a variety of ... -
The effect of scoliotic deformity on spine kinematics in adolescents
(BioMed Central, 2016-10-25)Background While adolescent idiopathic scoliosis (AIS) produces well characterized deformation in spinal form, the effect on spinal function, namely mobility, is not well known. Better understanding of scoliotic spinal ... -
Fabrication of Nano-rod Copper-polymer Composites by ã-Irradiation Route in a Heterogeneous System
(Chemical Society of Japan, 2001-02-26)Nano-rod copper-polymer composites were synthesized by γ-irradiation in a heterogeneous solution system under atmospheric pressure at room temperature. The product was characterized by XRD, TEM and IR spectrum, respectively. ... -
In situ Synthesis and Characterization of Spherical CdS/Polyacrylamide Nanocomposites by ã-Irradiation in W/O Microemulsions
(Chemical Society of Japan, 2001-05-07)Spherical CdS/polyacrylamide (CdS–PAM) nanocomposites were successfully synthesized in single step by γ-irradiation in a W/O microemulsion under ambient pressure at room temperature. The final product was characterized by ... -
Synthesis of Copper Sulfide Nanowhisker via Sonochemical Way and its Characterization
(Chemical Society of Japan, 2003-01-28)An ultrasonic irradiation route (USI route) is developed to synthesize whisker-like copper sulfide (Cu9S8) nanocrystals via the reaction between copper sulfate pantahydrate (CuSO4·5H2O) and thioacetamide (CH3CSNH2) in an ... -
Hydroxyapatite-Based Colloidal Gels Facilitate the Proliferation and Migration of Chondrocytes and the Adhesion of Umbilical Cord Mesenchymal Stem Cells
(Hindawi Publishing Corporation, 2014-12-29)Collective movement of cells that have been delivered on biomaterials for transplantation purposes would be a desirable attribute that would promote wound healing, cell proliferation, and eventual growth and regeneration ... -
An Automated Image-Based Method for Rapid Analysis of Chlamydia Infection as a Tool for Screening Antichlamydial Agents
(American Society for Microbiology, 2012-05-10)A major limitation in the identification of novel antichlamydial compounds is the paucity of effective methods for large-scale compound screening. The immunofluorescence assay is the preferred approach for accurate ... -
Boundary conditions in photoacoustic tomography and image reconstruction
(Society of Photo-optical Instrumentation Engineers, 2007-02-23)Recently, the field of photoacoustic tomography has experienced considerable growth. Although several commercially available pure optical imaging modalities, including confocal microscopy, two-photon microscopy, and optical ... -
Monkey brain cortex imaging by photoacoustic tomography
(Society of Photo-optical Instrumentation Engineers, 2008-08-20)Photoacoustic tomography (PAT) is applied to image the brain cortex of a monkey through the intact scalp and skull ex vivo. The reconstructed PAT image shows the major blood vessels on the monkey brain cortex. For comparison, ... -
Integration of photoacoustic imaging and high-intensity focused ultrasound
(Society of Photo-optical Instrumentation Engineers, 2010-03-23)We have developed an integrated photoacoustic imaging (PAI) and high-intensity focused ultrasound (HIFU) system for solid tumor treatments. A single-element, spherically focused ultrasonic transducer, with a central ... -
Physicochemical interactions at the dentin/adhesive interface using FTIR chemical imaging
(Society of Photo-optical Instrumentation Engineers, 2005-05-24)To date, much of our understanding of dentin bonding has been based on investigations performed on sound, healthy dentin. This is not the substrate generally encountered in clinical practice, rather dentists must frequently ... -
