| Abstract | Oxidative stress is associated with aging and most degenerative diseases: it contributes to clinical complications, organ failure and mortality. Furthermore, oxidative damage accumulation in macromolecules has been considered as a cause of cellular damage and pathology. Interestingly, it is unknown whether and to what extent oxidative stress contributes to the clinical worsening and most importantly, no common strategy exists about its measurement. This is partially due to the fact that many methods of measuring oxidative stress have proven unreliable and no single method exists enabling objective determination and characterization of oxidative stress in clinical settings whether in aging or in chronic disease. Some methods basing on the measurement of lipid peroxidation, as the determination of F2-isoprostanes or malondialdehyde, or on the measurement of DNA/RNA damage, as 8-hydroxydesoxyguanosine or 8-hydroxydesoxyguanine, are widely used to determine oxidative stress and gain more and more acceptance or are reliable supportive parameters. A set of methods exists for clinical set-ups based on the measurement of protein oxidation or oxidative protein modification. Some of these methods are gaining more and more acceptance due to the development of easy to use and stable methods. This includes the long known method of protein carbonyl determination in various methodological variations, but also the use of the determination of protein-based nitrotyrosine or HNE-modified proteins. All these methods can be used in clinical set-ups, but special care has to be taken on chemical and biological sample stability. It should be mentioned, that no single method, however, is yet alone able to characterize oxidative stress under clinical conditions and, therefore, various combinations of damage parameters are the most promising tools. |

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.
