Research4Life—Hinari, Agora, and Oare—is a cornerstone in Elsevier’s goal of achieving universal access to scientifi c, technical, and medical research information. We were among the founders of the initiative, and we are the largest contributor of journals to the programme. We have continually added more journals and now more books to the programme. Achieving our goal of universal access to hi...

Mitochondrial DNA's from many vertebrates (mammals,'-7 birds," 3 and amphibians8) and at least one invertebrate (sea urchin9) heretofore examined exhibit a remarkable structural similarity. All of these DNA's were found in the form of closed circular duplex molecules of approximately 5js in length, with an estimated molecular weight of 107 daltons. However, the estimates of the DNA content per ...

SUMMARY Pipit is a gene-centric interactive visualization tool designed to study structural genomic variations. Through focusing on individual genes as the functional unit, researchers are able to study and generate hypotheses on the biological impact of different structural variations, for instance, the deletion of dosage-sensitive genes or the formation of fusion genes. Pipit is a cross-platf...
