| Abstract | Antagonistic interactions between mercury (Hg) and selenium (Se), were evaluated in mouse (Mus musculus), as a mammalian model, in a series of controlled exposure experiments. The beneficial effect of Se against Hg toxicity involves a variety of biochemical and toxicological processes that have not been clarified yet. For this purpose, a metallomic workflow based on the use of size-exclusion chromatography (SEC) with inductively coupled plasma mass spectrometry (ICP-MS) detection was complemented with the speciation of selenoproteins and low molecular mass selenium species in serum and liver cytosolic extracts using a multidimensional approach based on SEC-AF-HPLC-ICPMS, using species-unspecific isotope dilution (SUID)-ICP-MS for selenium quantification. The results showed potential interactions between Hg/Se in organs and serum related to accumulation and detoxification processes, in addition to the effects of mercury on selenoproteins in hepatic cytosolic extracts and bloodstream when both elements are administrated at the same time. These results provide information about elements distribution, interactions and homeostasis and reveal the potential of metallomic approaches in exposure experiments. |

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.
