| Abstract | Type I collagen and hyaluronic acid are both the main components of bone extracellular matrix, and play important roles in regulating a cell's behavior. In this study, the synergistic effects of type I collagen (Col) and hyaluronic acid (HA) on the biological properties of Col/HA-multilayer-modified titanium coatings were investigated. In vitro, the results of human mesenchymal stem cells culture indicated that Col/HA-multilayers-modified titanium coatings (TC-AA(C/H)6) could better improve a cell's adhesion, proliferation, and differentiation, compared with collagen-modified titanium coatings (TC-AAC) and hyaluronic acid-modified titanium coatings (TC-AAH). In vivo, the micro-CT images indicated that bone trabecula around TC-AA(C/H)6 were significantly more than with TC-AAC and TC-AAH. The fluorescence micrograph showed more active new bone formation around implants in TC-AA(C/H)6 group than in the TC-AAC and TC-AAH groups in the first month. Measurement of the bone-implant contact on the histological sections indicated there was significantly good osteointegration around TC-AA(C/H)6 implants than with the other two modified titanium coatings. All of these results demonstrated that there exists favorable synergistic effects of type I collagen and hyaluronic acid. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
