© The Royal Society of Chemistry.We investigated the three soft corals Sarcophyton stellatum, Capnella fungiformis and Lobophytum crassum and the sponge Pseudoceratina arabica, which have been collected at the coast of Madagascar. In addition to previously known marine natural products, S. stellatum provided the new (+)-enantiomer of the cembranoid (1E,3E,11E)-7,8-epoxycembra-1,3,11,15-tetraene (2). Capnella fungiformis afforded three new natural products, ethyl 5-[(1E,5Z)-2,6-dimethylocta-1,5,7-trienyl]furan-3-carboxylate (6), ethyl 5-[(1E,5E)-2,6-dimethylocta-1,5,7-trienyl]furan-3-carboxylate (7) and the diepoxyguaiane sesquiterpene oxyfungiformin (9a). The extracts of all three soft corals exhibited moderate activities against the malarial parasite Plasmodium falciparum. Extracts of the sponge Pseudoceratina arabica proved to be very active against a series of Gram-positive and Gram-negative bacteria

Rescue Chimney Technique after the Loss of All Branches of the Aortic Arch

IntroductionThe hybrid procedure is a compromise between open and total endovascular repairs of aortic arch aneurysms. However, this technique is not free from complications.ReportWe present the use of the chimney technique, after the loss of all branches of the aortic arch during thoracic endovascular aortic repair, in a patient with a previous partial debranching of the aortic arch.DiscussionThe coverage of the vital vessels of the aortic arch during stent graft deployment could be linked to hypertension, anatomical abnormalities, or patient movements. In such cases, the chimney technique may be the only possible rescue procedure
