| Abstract | Polymorphisms in the δ-aminolevulinic acid dehydratase (ALAD) and the vitamin D receptor (VDR) genes may modify lead metabolism and neurotoxicity. Two cohorts of children were examined for hearing [pure-tone audiometry (PTA), brain stem auditory evoked potentials (BAEP)], acoustic otoemission (transient emission evoked by a click) and blood-lead concentrations (B-Pb). The children were genotyped for polymorphisms in ALAD and VDR. The median B-Pbs were 55 and 36µg/L in the two cohorts (merged cohort 45µg/L). B-Pb was significantly associated with impaired hearing when tested with PTA (correlation coefficient rS=0.12; P<0.01), BAEP (rS=0.18; P<0.001) and otoemission (rS=-0.24; P<0.001). VDR significantly modified the lead-induced effects on PTA. Carriers of the VDR alleles BsmI B, VDR TaqI t and VDR FokI F showed greater toxic effects on PTA, compared to BsmI bb, VDR TaqI TT and VDR FokI ff carriers. No significant interaction was found for ALAD. Lead impairs hearing functions in the route from the cochlea to the brain stem at low-level exposure, and polymorphisms in VDR significantly modify these effects. |

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.
