| Abstract | Xenopus tropicalis embryos were exposed for 48 h to mixtures of triphenyltin and LGD1069 (an agonist of the retinoid X receptor). The index of fin deficiency (IFD) of the embryos increased in the triphenyltin-treated groups, and the index of axis deficiency (IAD) increased in LGD1069-treated groups in a concentration-dependent manner. When embryos were exposed to mixtures of 5µgSn/L triphenyltin and 1-30 µg/L LGD1069, IFD decreased from 2.9 to 0.6 and IAD increased from 0.1 to 2.4 with increasing LGD1069 concentrations. Conversely, when embryos were exposed to mixtures of 15 µg/L LGD1069 and 1-10 µg Sn/L triphenyltin, IFD increased from 0.1 to 3.0 with increasing triphenyltin concentrations. Co-exposure induced some new phenotypes, such as posteriorized anus. These results suggest that LGD1069 suppressed the teratogenicity of triphenyltin and that the retinoid X receptor was involved in triphenyltin-induced teratogenicity. Histological observations indicate that co-exposure inhibited the invagination of the yolk plug. |

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.
