Antibacterial coatings on titanium implants Tập 91B Số 1 - Trang 470-480 - 2009
Lingzhou Zhao, Paul K. Chu, Qian Zhang, Zhifen Wu
AbstractTitanium and titanium alloys are key biomedical materials because of
their good biocompatibility and mechanical properties. Nevertheless, infection
on and around titanium implants still remains a problem which is usually
difficult to treat and may lead to eventual implant removal. As a result,
preventive measures are necessary to mitigate implant‐frelated infection. One
important strategy ... hiện toàn bộ
Three‐dimensional printing of porous ceramic scaffolds for bone tissue engineering Tập 74B Số 2 - Trang 782-788 - 2005
Hermann Seitz, Wolfgang Rieder, Stephan Irsen, Barbara Leukers, Carsten Tille
AbstractThis article reports a new process chain for custom‐made
three‐dimensional (3D) porous ceramic scaffolds for bone replacement with fully
interconnected channel network for the repair of osseous defects from trauma or
disease. Rapid prototyping and especially 3D printing is well suited to generate
complex‐shaped porous ceramic matrices directly from powder materials.

Bioresorbable nanofiber‐based systems for wound healing and drug delivery: Optimization of fabrication parameters Tập 70B Số 2 - Trang 286-296 - 2004
Dhirendra S. Katti, Kyle Robinson, Frank Ko, Cato T. Laurencin
AbstractWound healing is a complex process that often requires treatment with
antibiotics. This article reports the initial development of a biodegradable
polymeric nanofiber‐based antibiotic delivery system. The functions of such a
system would be (a) to serve as a biodegradable gauze, and (b) to serve as an
antibiotic delivery system. The polymer used in this study was
poly(lactide‐co‐glycolide)... hiện toàn bộ
Hierarchically biomimetic bone scaffold materials: Nano‐HA/collagen/PLA composite Tập 69B Số 2 - Trang 158-165 - 2004
Susan Liao, Fuzhai Cui, Wei Zhang, Qingling Feng
AbstractA bone scaffold material (nano‐HA/ collagen/PLA composite) was developed
by biomimetic synthesis. It shows some features of natural bone both in main
composition and hierarchical microstructure. Nano‐hydroxyapatite and collagen
assembled into mineralized fibril. The three‐dimensional porous scaffold
materials mimic the microstructure of cancellous bone. Cell culture and animal
model tests ... hiện toàn bộ
Interaction of cells and nanofiber scaffolds in tissue engineering Tập 84B Số 1 - Trang 34-48 - 2008
Jayarama Reddy Venugopal, Sharon Low, Aw Tar Choon, Seeram Ramakrishna
AbstractNanofibers and nanomaterials are potentially recent additions to
materials in relation to tissue engineering (TE). TE is the regeneration of
biological tissues through the use of cells, with the aid of supporting
structures and biomolecules. Mimicking architecture of extracellular matrix is
one of the challenges for TE. Biodegradable biopolymer nanofibers with
controlled surface and intern... hiện toàn bộ
A protocol for rheological characterization of hydrogels for tissue engineering strategies Tập 102 Số 5 - Trang 1063-1073 - 2014
Jonathan M. Zuidema, Christopher J Rivet, Ryan J. Gilbert, Faith A. Morrison
AbstractHydrogels are studied extensively for many tissue engineering
applications, and their mechanical properties influence both cellular and tissue
compatibility. However, it is difficult to compare the mechanical properties of
hydrogels between studies due to a lack of continuity between rheological
protocols. This study outlines a straightforward protocol to accurately
determine hydrogel equi... hiện toàn bộ
Effectiveness of autologous preparation rich in growth factors for the treatment of chronic cutaneous ulcers Tập 84B Số 2 - Trang 415-421 - 2008
Eduardo Anitua, José Javier Aguirre, Jaime Algorta, Eduardo Ayerdi, Ana I. Cabezas, Gorka Orive, Isabel Andı́a
AbstractAutologous Preparation Rich in Growth Factors (PRGF), a small volume of
plasma enriched in platelets, is a novel therapeutic strategy for the
acceleration of the wound healing of a wide range of tissues because of the
continuous release of multiple growth factors, including PDGF‐AB, TGF‐β1, IGF‐I,
HGF, VEGF‐A, and EGF. In this article, we have characterized the PRGF
preparation and designe... hiện toàn bộ
Application of crosslinkers to dentin collagen enhances the ultimate tensile strength Tập 80B Số 1 - Trang 268-272 - 2007
Ana K. Bedran‐Russo, Patricia N R Pereira, Wagner Rodrigues Duarte, James L. Drummond, Mitsuo Yamauchi
AbstractThe stabilization of dentin collagen with biocompatible crosslinking
agents may be of clinical importance to improve dentin bond strength. The
present study aimed to evaluate the effect of three collagen crosslinking agents
on the ultimate tensile strength (UTS) of undemineralized and demineralized
dentin. Ten freshly extracted sound molars were sectioned into 0.5 × 0.5 mm2
thick beams. Th... hiện toàn bộ

Comparison of osteoblast‐like cell responses to calcium silicate and tricalcium phosphate ceramics in vitro Tập 80B Số 1 - Trang 174-183 - 2007
Siyu Ni, Jiang Chang, Lee Chou, Wanyin Zhai
AbstractCalcium silicate ceramics have been proposed as new bone repair
biomaterials, since they have proved to be bioactive, degradable, and
biocompatible. β‐tricalcium phosphate ceramic is a well‐known degradable
material for bone repair. This study compared the effects of CaSiO3 (α‐, and
β‐CaSiO3) and β‐Ca3(PO4)2 (β‐TCP) ceramics on the early stages of rat
osteoblast‐like cell attachment, proli... hiện toàn bộ
