| Abstract | Combined phenotypes of cells with membrane and intracellular expression of apoptosis and proliferation regulation markers (p53, bcl-2, CD95, CD95L, Ki-67) were studied by flow cytometry of cell suspension from thyroid tissue specimens from patients with autoimmune diseases, adenoma, and thyroid cancer. The incidence of cell groups with phenotypes p53/Ki-67, p53/CD95, bcl-2/Ki-67, bcl-2/CD95, CD95/Ki-67, p53/CD95L, CD95/CD95L, and bcl-2/CD95L was evaluated and the density of receptor distribution on/in each cell group are presented. Patients with autoimmune diseases had high incidence of cells with phenotypes p53/Ki-67, p53/CD95, bcl-2/Ki-67, bcl-2/CD95, CD95/Ki-67, p53/CD95L, CD95/CD95L, and bcl-2/CD95L; cells with the bcl-2/CD95 phenotype were the most incident. Patients with thyroid adenoma had high levels of cells with p53/CD95L phenotype, while patients with thyroid cancer had significantly lower levels of p53 expression in the p53/CD95L cell group. The density of CD95L receptors on CD95/CD95L-positive cells was 4-7-fold higher in patients with thyroid tumors; the density of CD95L receptors on CD95/CD95L cells was maximum in thyroid adenoma and minimum in thyroid cancer. These data indicate differences in the expression of apoptosis and proliferation markers in thyroid adenoma, cancer, and autoimmune diseases. Analysis of the expression of these markers in the above diseases can be useful for differential diagnosis. |

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.
