| Abstract | This study focused on designing a large-scale producible vehicle for the pharmaceutically important compound berberine, to simultaneously improve its bioavailability against cancer cells and reduce cytotoxicity toward normal cells. This vehicle is composed of chitosan and tripolyphosphate, and was prepared with a simple ionic cross-linking method. The properties of the berberine-loaded chitosan-tripolyphosphate nanoparticles (BB-LCTNP) were dependent on berberine, chitosan, and tripolyphosphate concentrations. The bioavailability improvement and anticancer efficiency of the BB-LCTNPs were analyzed using MDA-MB-435 and Colo-205 cells. The results revealed that the particle size, loading efficiency, and IC50 of the BB-LCTNPs can be controlled easily. The pharmacodynamic availability of berberine increased up to 3 times when loaded into the nanoparticles because they directly targeted cancer cell nuclei. Moreover, the BB-LCTNPs were non-toxic toward normal cells. In vivo studies revealed that BB-LCTNPs can reduce drug dosages up to 3 times and suppress tumor growth. The surfaces of the prepared BB-LCTNPs were modified using mPEG acid, but the in vitro and in vivo studies of these particles are currently ongoing. |

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.
