|Abstract||Developing adipose tissue-engineered construct to mend soft tissue defects arising from traumatic injury, tumor resections, and maxillofacial abnormalities is of prime importance in plastic and reconstructive surgical procedures. It is apparent that the clinical outcome of classic techniques like adipose tissue transplantation is unpredictable, with graft resorption, lack of vascularization, and impaired functionality. In this prospective, the concept of tissue engineering was adopted to fabricate a combination product with biphasic calcium phosphate (BCP) and rat adipose-derived mesenchymal stem cells (ASCs) toward the development of an adipose tissue construct. BCP, a combination of hydroxyapatite and a-tricalcium phosphate, was characterized for its physiochemical properties, and ASCs were characterized for their stemness. The cellceramic interactions were demonstrated in vitro, whereas adipogenesis was picturesquely depicted by Nile red-stained multilocular adipocyte-like cells. Subsequently, the three-dimensional cellceramic-engineered construct was implanted in the rat dorsal muscle for a period of 3 weeks to demonstrate the efficacy of the tissue construct in vivo. Interestingly, the histology of the postimplanted tissue construct revealed the distribution of chicken wire net-like fat cells within the vicinity of the construct. The efficacy of cell transplantation via the scaffold was traced using fluorescent in situ hybridization by labeling the Y chromosome. Thus, the ceramic-based construct may be a good option for reconstruction therapies. (C) 2012 Wiley Periodicals, Inc. J Biomed Mater Res Part A:, 2012.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at 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 Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
