41. Protein and Solvent Dynamics: How Strongly Are They Coupled?
Topic: Biomaterials
Published: 1/1/2004
Authors: G Caliskan, D Mechtani, J H Roh, A Kisliuk, Alexei Sokolov, S Azzam, Marcus T Cicerone, Sheng Lin-Gibson, I Peral
Abstract: Analysis of Raman spectra of protein lysozyme demonstrates that its dynamics follow well the dynamics of solvents glycerol and trehalose. The protein s fast conformational fluctuations and low-frequency vibrations and their temperature variations are ...

42. Quantification of Inflammatory Cellular Responses Using Real-Time Polymerase Chain Reaction
Topic: Biomaterials
Published: 5/1/2004
Authors: L A Bailey, N. R. Washburn, Carl GEORGE Simon Jr, E S Chan, Francis W Wang
Abstract: : The introduction of tissue engineering approaches for the repair and replacement of human body components extends the application and importance of synthetic materials (biomaterials). Implanted biomaterials frequently evoke inflammatory responses, ...

43. Relative Rigidity of Cell-Substrate Affects Hepatic and Hepatocellular Carcinoma Cell Migration
Topic: Biomaterials
Published: 12/3/2012
Authors: Martin Y Chiang, Hongbing Wang, Li Zhong, Qiaoyan Tan, Gurinder K Singh, Song Li, Li Yang, Yanzi Yangben
Abstract: Polyacrylamide gels with different stiffness and glass were employed as substrates to investigate how substrate stiffness affects the cellular stiffness of adherent hepatocellular carcinoma (HCCLM3) and hepatic (L02) cells. The interaction of how cel ...

44. Synthesis, characterization and evaluation of novel, anti-bacterial monomers for dental and biomedical applications
Topic: Biomaterials
Published: 8/16/2009
Authors: Joseph M Antonucci, Bruce Owen Fowler, Diana N. Zeiger, Nancy J Lin, Sheng Lin-Gibson
Abstract: Although progress has been made in reducing polymerization shrinkage through resin and filler phase modifications, and in designing improved dental adhesion systems, composite fillings still fail clinically because of bacterial infiltration and secon ...

45. THE ROLE OF TOOTH ENAMEL MECHANICAL PROPERTIES IN PRIMATE DIETARY ADAPTATION
Topic: Biomaterials
Published: 6/27/2012
Authors: Paul Constantino, James J. Lee, Yvonne Beatrice Gerbig, Adam Hartstone-Rose, Mauricio Talebi, Brian Ronald Lawn, Peter Lucas
Abstract: Primate teeth adapt to the physical properties of foods in a variety of ways including changes in occlusal morphology, enamel thickness, and overall size. We conducted a comparative study of extant primates to examine whether their teeth also adap ...

47. Tissue Engineered Scaffolds for Screening Nanoparticle - Cell Interactions
Topic: Biomaterials
Published: 4/21/2010
Authors: Kavita M Jeerage, Elisabeth Mansfield, Tammy L. Oreskovic, Nikki Serene Rentz, Timothy P Quinn
Abstract: Long-term studies of nanoparticle-cell interactions require an advanced tissue-like environment in which nanoparticles are encapsulated with a population of cells for real-time and end-point analysis. By using soft tissue-mimicking hydrogels, the cel ...

48. Tooth chipping can reveal bite forces and diets of fossil hominins
Topic: Biomaterials
Published: 6/16/2010
Authors: Paul Constantino, James J. Lee, H Chai, Bernhard Zipfel, Charles Ziscovici, Brian Ronald Lawn, Peter Lucas
Abstract: Fossil hominin tooth enamel often exhibits antemortem edge chipping (Robinson 1954; Tobias 1967; Wallace 1973). Here we apply a simple fracture equation to estimate peak bite forces from the sizes of such chips. This equation, previously validated ...

49. Towards In-Situ Monitoring of Cell Growth in Tissue Engineering Scaffolds: High Resolution Optical Techniques
Topic: Biomaterials
Published: 1/12/2004
Authors: Marcus T Cicerone, Joy P Dunkers, N Washburn
Abstract: Inability to obtain cellular-level information about progress of cell growth in tissue-engineering (TE) scaffolds is a pervasive problem. We demonstrate that a confocal microscope with two collinear contrast mechanisms, optical coherence, and fluore ...

50. Transverse Fracture of Brittle Bilayers Relevance to Failure of All-Ceramic Dental Crowns
Topic: Biomaterials
Published: 3/1/2006
Authors: Jeonghwan Kim, Sanjit Bhowmick, Ilja Hermann, Brian Ronald Lawn
Abstract: A study is made of the behavior of cracks approaching interfaces in all-ceramic crown-like bilayers. Flat specimens are fabricated by fusing porcelain veneers onto Y-TZP and alumina core ceramic plates, with veneer/core matching to minimize residual ...
