    • The Rat Genome Database (RGD) is a NIH funded project who’s stated mission is “to collect, consolidate, and integrate data generated from ongoing rat genetic and genomic research efforts and make these data widely available to the scientific community.” In a collaboration between the Medical College of Wisconsin, the Jackson Lab, the National Center for Biotechnology and Information and the Genetics Lundberg Laboratory, Gothenburg, Sweden, RGD has been created to meet these stated aims. The primary focus of RGD is to aid Rat researchers in their work studying the rat as a model organism for human disease. To support these studies we have integrated a large amount of rat genetic and genomic resources in RGD and these are constantly being expanded through ongoing literature curation. One of the major features of RGD version 1.1, released in January of this year, is incorporation of QTL data to facilitate physiological genomics studies relating disease with the genome. In addition, a dynamic sequence-based homology tool is in final testing which will enable Rat, Mouse and Human researchers to view mapped genes and sequences and their locations in the other two organisms. We hope to release this tool in the second quarter of 2001. This will facilitate the application of results in one species to experiments in another species. In collaboration with the Mouse Genome Database and NCBI, close links are being created between RGD and MGD, LocusLink and UniGene to increase access to each set of data. To support its other general functions RGD has a variety of tools available for the rat researcher, plus ones that are equally useful to researchers working in other organisms and a sampling of these tools will be presented. Thus RGD is not only a valuable resource for those working with the rat but also for researchers in other model organisms wishing to harness the existing genetic and physiological data available in the rat to complement their own work.

  • High-valent Ruthenium-Manganese Complexes for Solar Energy Production.
  • 2001
  • Ingår i: PS2001 Proceedings.
  • Konferensbidrag (refereegranskat)abstract
    • We present progress in the development of artificial photosynthesis, as a means to harvesting and storage of solar energy. The plan is to compose molecular systems that combine known photochemistry with emerging functional model compounds. A photochemical device for solar energy conversion contains a photosensitizer, an electron acceptor system and a donor system that prevents charge recombination. Our goal is to utilize water as sacrificial electron donor, which will allow a net production of reducing equivalents, and the ultimate production of fuel. The only light-driven molecular catalyst for water oxidation exists in Photosystem II (PSII), which has a tetranuclear Mn-cluster in the active site. Here we present several Mn-compounds, that we have developed for the purpose of creating water-oxidizing catalysts. Our idea is to link Ru-tris(bipyridine) derivatives, which mimicks the function of the primary donor in PS II, with manganese complexes, mimicking the tetra-Mn cluster on the PSII donor side. We have constructed a number of heteronuclear complexes, containing a Ru-photosensitizer and various Mn-complexes. The compounds have been characterized with regards to their photophysical and photochemical properties, redox potentials and structure. The most promising compounds are capable of undergoing several electron transfers from the Mn-complex to the photosensitizer, leaving 3 to 4 oxidizing equivalents on the Mn. In the latest development, we have constructed ligands that stabilize higher oxidation states in Mn, in order to promote formation of Mn(V) which many believes is an intermediate in the water oxidation mechanism.

  • Rhodium complexes containing O-bonded NHxMe2-xCHO (x=0, 1, 2) : X-ray structure of Rh(PPh3)(3)(OCHNHMe) CIO4
  • 2001
  • Ingår i: Helvetica Chimica Acta. - 0018-019X .- 1522-2675. ; 84:10, s. 3075-3083

    • Displacement of norbornadiene (nbd; bicyclo[2.2.1]hepta-2,5-diene) from [Rh(PPh3)(2)(nbd)]ClO4 by hydrogenation in the presence of PPh3 and formamide or Me-substituted derivatives, results in the formation of O-bonded formamide complexes [Rh(PPh3)(3)(OCHNHxMe2-x)]ClO4 (x=0, 1, 2) rather than N-bonded derivatives. These have been characterised by spectroscopic measurements and, in the case of [Rh(PPh3)(3)(OCHNHMe)]ClO4, by X-ray crystallography. All undergo oxidative addition with H-2, and the rates of ligand exchange in the Rh-I and Rh-III complexes have been determined by magnetisation-transfer measurements.
