| Abstract | Dietary fiber (DF) and resistant starch (RS) in the grains of cereals are fermented into short chain fatty acids (SCFA), including butyrate, propionate, and acetate, in the large intestine, and are absorbed into the blood. Effectiveness of SCFA in reducing myocardial damage was evaluated in a rat model of 30 min ischemia and 3 h reperfusion with administration of SCFA (10 mg/kg) by peritoneal injection 1 h before occlusion. Butyrate and propionate significantly attenuated infarct size, an indicator of myocardial damage, when assessed by 2,3,5-triphenyltetrazolium chloride staining, reduced apoptosis in terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling staining, and increased Bcl-2/Bax ratio, a determinant of cell survival in the apoptotic pathway. In addition, butyrate significantly attenuated the level of caspase-3, an executioner caspase, in an immunohistochemical assay. These results demonstrate that butyrate and propionate, produced by fermentation of DF and RS in the large intestine, could prevent myocardial infarction by attenuating apoptosis, possibly through inhibition of histone deacetylases. Thus, varieties of cereals or diets that produce a large amount of butyrate and propionate by fermentation could be beneficial in reducing myocardial infarction. |

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.
