| Abstract | Platelet-derived growth factor (PDGF) has been suggested to play an important role in wound healing. In this study wound fluid collected from patients after radical mastectomy was analyzed for PDGF-related factors. Analysis revealed the presence of two PDGF-related peptides of 16-17 kDa and 34-36 kDa. These PDGF-related peptides were purified by using anti-PDGF immunoaffinity techniques and found to possess both chemotactic and mitogenic activities for NIH 3T3 cells in vitro. Surprisingly, we could not detect authentic native PDGF (30 kDa) or PDGF A or B chain in any of the wound-fluid samples examined. These results indicate that PDGF-related peptides are present in normal human wound fluid, whereas PDGF A- and B-chain peptides are absent or only present in trace amounts relative to the total PDGF-related biological activity. |

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.
