|Abstract||Type 1 diabetes is a chronic disorder that results due to auto immune destruction of insulin producing cells, which leads to hyperglycemia in the blood. The development of an ideal scaffold for maintaining the structure and function of islets is a challenge in the field of pancreatic tissue engineering. In this study, gelatin (G) as well as gelatin/PVP (GP) semi interpenetrating polymer network scaffolds have been fabricated by freeze drying technique and cross linked with gluteraldehyde (GTA) and 1-Ethyl-3-[3-dimethylaminopropyl] carbodiimide hydrochloride (EDC), which was abbreviated as GG, GPG (cross linked with GTA) GE and GPE (cross linked with EDC). The presence of gelatin and PVP in GPE and GPG scaffolds was confirmed through FTIR and TGA. The medium uptake ability of GPE and GPG scaffolds were higher than GG and GE scaffolds. The scaffolds were then analyzed for its ability to maintain the viability and function of mouse pancreatic islet cells in vitro. The results showed that the islets can adhere, but they tend to lose the structure and function on all the scaffolds after day 7, except on GPE where they remained intact up to day 30. Thus the present study clearly demonstrates that gelatin incorporated with PVP and cross linked with EDC scaffolds could support and maintain islet cells for prolonged period.|

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.
