| Abstract | Cadmium (Cd) is an important inorganic toxicant in the environment which impacts on human health. A metallomic approach based on size-exclusion chromatography (SEC) coupled to inductively coupled plasma-mass spectrometry (ICP-MS) and multidimensional chromatography separation based on SEC coupled to affinity chromatography 2D-SEC-AF-ICP-MS have been applied to achieve a better understanding of the function, detoxification processes and regulation of metals in mice (Mus musculus) under controlled exposure to both Cd and Cd plus 77Se. Isotopic dilution analysis (IDA) was performed to quantify selenium containing proteins in mice plasma with ICP-qMS as a multielemental detector. Additionally, isotope pattern deconvolution (IPD) was applied to study the fate of enriched 77selenite in mice subjected to cadmium exposure and the effect of selenoprotein production in plasma. Moreover, the affinity of Cd for SeP in plasma of mice was corroborated using anion exchange chromatography (AEC) after AF separation and identified by organic mass spectrometry. This work illustrates the high reliability of the integrated use of inorganic and organic mass spectrometry to get a metallomic approximation, which provides a good alternative to gain deep insight into the fate of elements in exposed organisms, providing information about metal trafficking, interactions and homeostasis. |

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.
