| Abstract | Mechanisms of neuronal cell death in apoptosis and necrosis are examined. Neurotoxic processes underlying cellular destruction may involve N-methyl-D-aspartate (NMDA) receptor activation and/or activation of neuronal nitric oxide synthase but the depletion of energy and generation of free radicals appears to be critical. In Alzheimer’s disease the damaging effects of peroxynitrite and exposure to β-amyloid peptide is evident. Mitochondrial dysfunction is involved in several neurodegenerative diseases including Parkinson’s disease, amyotrophic lateral sclerosis, Huntington’s disease as well as Alzheimer’s disease and in these disorders the innovations offered by techniques ranging from transgenic mouse models of the disorder to cell culture preparations are remarkable. Agents of neuroprotection and neurorestoration possess either characteristics specific to particular disorders or have a general applicability or both. The vast array of agents available are for the most part the objectives of laboratory examinations but an increasing selection of compounds are reaching the clinical necessities thereby influencing current strategic notions to modify tactical contingencies. Among the agents listed are included: inhibitors of the enzyme poly-ADP-ribose polymerase, inhibition of apoptotic cell death, agents acting on mitochondrial permeability transition, excitatory amino acid antagonists, applications of neurotrophins, immunophilins, agents influencing heme oxygenase-1 expression and iron sequestration in aging astroglia, improvements in mitochondrial energy production or buffering, and finally dopaminemimetics with differential affinities for dopamine receptors. |

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.
