Abstract: A use of an anti-inflammatory polysaccharides composition comprising fucans and galactans to inhibit the release of one or more of IL-8, PGE2 and VEGF by a cell activated during an inflammatory process and an anti-inflammatory composition comprising a ratio of brown algae fucans/red algae galactans of between about 2.5/1 (w/w) to about 40/1 (w/w), the galactans having a molecular weight higher than about 100 kDa, and the fucans having a molecular weight between about 0.1 kDa and 100 kDa.

Abstract: A floating unsinkable nautical craft comprises a hull having a keel portion below the water line and an upper portion. A longitudinally extending passenger compartment is provided at least mostly in the keel portion while a pilot's cockpit and passenger entrance are provided in the upper portion. Longitudinally extending dome-shaped observation windows are provided in the sides of the passenger compartment, the windows being of such length and height as to provide several passengers with an underwater view horizontally and downwards. A separate stabilization and bouyancy structure is connected rigidly to the upper portion of the hull and extends laterally to both sides with flotation and water ballast chambers at the ends. A pump is provided for varying the ballast to vary the draught of the craft.
