Boron isotope ratios of samples from ODP Leg 125 sites at a serpentine seamount, Mariana forearc

Serpentinite clasts and muds erupted from Conical Seamount, Mariana forearc, show substantial enrichment in boron (B) and 11B (delta11B up to +15?) relative to mantle values. These elevated B isotope signatures result from chemical exchange with B-rich pore fluids that are upwelling through the seamount. If the trends of decreasing delta11B with slab depth shown by cross-arc magmatic suites in the Izu and Kurile arcs of the western Pacific are extended to shallow depths (~25 km), they intersect the inferred delta11B of the slab-derived fluids (+13x) at Conical Seamount. Simple mixtures of a B-rich fluid with a high delta11B and B-poor mantle with a low delta11B are insufficient to explain the combined forearc and arc data sets. The B isotope systematics of subduction-related rocks thus indicate that the fluids evolved from downgoing slabs are more enriched in 11B than the slab materials from which they originate. Progressively lower delta11B in arc lavas erupted above deep slabs reflects both the progressive depletion of 11B from the slab and progressively greater inputs of mantle-derived B. This suggests that the slab releases 11B-enriched fluids from the shallowest levels to depths greater than 200 km.

The crystal structure of human interferon β at 2.2-Å resolution

Type I interferons (IFNs) are helical cytokines that have diverse biological activities despite the fact that they appear to interact with the same receptor system. To achieve a better understanding of the structural basis for the different activities of α and β IFNs, we have determined the crystal structure of glycosylated human IFN-β at 2.2-Å resolution by molecular replacement. The molecule adopts a fold similar to that of the previously determined structures of murine IFN-β and human IFN-α2b but displays several distinct structural features. Like human IFN-α2b, human IFN-β contains a zinc-binding site at the interface of the two molecules in the asymmetric unit, raising the question of functional relevance for IFN-β dimers. However, unlike the human IFN-α2b dimer, in which homologous surfaces form the interface, human IFN-β dimerizes with contact surfaces from opposite sides of the molecule. The relevance of the structure to the effects of point mutations in IFN-β at specific exposed residues is discussed. A potential role of ligand–ligand interactions in the conformational assembly of IFN receptor components is discussed.

Barralet, del. ; W. Harrison, sct., Philada. It was published by Philip Carrigain in 1816. Scale [ca. 1:200,000]. This layer is image 5 of 6 total images, representing the center west portion of the six sheet source map. The image inside the map neatline is georeferenced to the surface of the earth and fit to the New Hampshire State Plane coordinate system (NAD 1983 in Feet) (Fipszone 2800). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as roads, drainage, public buildings, schools, churches, industry locations (e.g. mills, factories, mines, etc.), selected private buildings with names of property owners, town boundaries, land grants, and more. Relief shown pictorially and by hachures. Includes area notes, text, and table of population.
