| Abstract | Statistical analysis can provide objective, quantitative informations on both the tonal behavior and the underlying texture of conventional 2-D echocardiograms. In this respect, the myocardium of chronic uremic patients is of special interest. Its histologic pattern, characterized by interstitial fibrosis, as well as by deposits of different substances (calcium, aluminum, collagen) within the fibers, yields abnormal echoreflectivity, qualitatively described by conventional ultrasonic examinations, and hypertrophy. Thirty-one patients under maintenance hemodialysis treatment underwent 2-D echocardiography at the end of the dialytic procedure. Sixteen patients with systemic hypertension, comparable left ventricle hypertrophy and normal renal function served as control group. After digitization of the images obtained from a 4-chamber apical view, statistical analyses were performed on regions of interest localized within the interventricular septa. Various first order parameters significantly discriminated the two groups (p<0.01), while no remarkable difference was detected in second order parameters. It is concluded that the abnormal echo response could be related to deposits of highly reflective substances within the myocardium.< |

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.
