| Abstract | The central nervous system (CNS) is of particular importance in human immunodeficiency virus type 1 (HIV-1) infection. First, the CNS may be difficult to access for anti-retroviral treatment and may become a sanctuary for residual viruses. Second, HIV-1 infection may lead to AIDS dementia complex (ADC) culminating in HIV-1 encephalitis. In order to examine the pattern of drug resistance and the role of encephalitis in enhancing viral redistribution to the CNS, we compared pol gene quasispecies of the spleen and brain in two patients with and two patients without HIV-1 encephalitis, who had been treated with zidovudine (AZT). Although a variable degree of AZT resistance was noted in both the spleen and brain of all patients, phylogenetic analysis indicated that quasispecies developed rather independently in the systemic circulation (spleen) and CNS (brain) of patients without HIV-1 encephalitis, while similar pol gene sequences were obtained from the two compartments of patients with HIV-1 encephalitis. env gene V3 region of patients with HIV-1 encephalitis showed distinct quasispecies in the spleen and brain. Our results suggest that HIV-1 redistribution to CNS is more active in cases with encephalitis and that HIV-1 distributed late to CNS grow actively under certain selective pressure exerted on the V3 region of the env gene. |

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.
