| Abstract | The effect of the metabolic drug Cytoflavin (CF) with antihypoxic and antioxidative properties on human dermal fibroblasts in the model of ischemia/reoxygenation in vitro was studied. It was revealed that, during the reoxygenation period after ischemia, the cell death rate in culture with CF appeared to be 2–2.7 times lower than in control cultures. Recovery of ATP synthesis after ischemia was 2.1 times faster in culture with CF. The drug effectively reduced the level of reactive oxygen species (ROS) in fibroblasts after H$_{2}$O$_{2}$ treatment, which allowed their survival to be maintained at the level of control cells. Pretreatment of cells with CF for one day ensured the maintenance of a normal level of ROS during the investigated time period in fibroblasts subjected to H$_{2}$O$_{2}$ treatment and reduced H$_{2}$O$_{2}$-induced cell death by almost one-third as compared to non-pretreatment control cells. Addition of CF into the culture medium in the postischemic period showed no effect on Hsp70 synthesis, but led to a decrease in GRP78 synthesis, raised after ischemia, to the control level, indicating a resolution of unfolded protein response in these cells and normalization of the functioning of their endoplasmic reticulum. |

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.
