    1. Cyano-stabilized triphenylphosphonium ylids.
      Fernando F Castañeda, Clifford A CA Bunton, ... María Teresa MT Garland

      Acta Crystallogr C 63(Pt 1):o65-7 (2007) PMID 17206060

      Crystalline cyano-stabilized triphenylphosphonium ylids with keto or ester groups give rise to an extended electronic delocalization. In methyl 2-cyano-2-(trimethylphosphonio)ethenoate, Ph3P=C(CN)CO2CH3 or C22H18NO2P, (I), and 1-cyano-1-(trimethylphosphonio)prop-1-en-2-olate, Ph3P=C(CN)CO-CH3 or C22...
    2. Cytokine and chemokine dynamics differ between rats and mice after collagen implantation.
      Daniël T Luttikhuizen, Martin C Harmsen, and Marja J A van Luyn

      J Tissue Eng Regen Med 1(5):398-405 (2007) PMID 18038434

      We hypothesized that the observed difference in FBR between rats and mice correlate with different expression dynamics of cytokines and chemokines, which are key orchestrators of the FBR. After implantation of hexamethylene diisocyanate cross-linked dermal sheep collagen, the overall gene expression...
    3. Direct cyanation of heteroaromatic compounds mediated by hypervalent iodine(III) reagents: In situ generation of PhI(III)-CN species and the...
      Toshifumi T Dohi, Koji K Morimoto, ... Yasuyuki Y Kita

      J Org Chem 72(1):109-16 (2007) PMID 17194088

      Hypervalent iodine(III) reagents mediate the direct cyanating reaction of a wide range of electron-rich heteroaromatic compounds such as pyrroles 1, thiophenes 3, and indoles 5 under mild conditions (ambient temperature), without the need for any prefunctionalization. Commercially available trimethy...
    4. Diisocyanate asthma and gene-environment interactions with IL4RA, CD-14, and IL-13 genes.
      David I DI Bernstein, Ning N Wang, ... Gurjit K Khurana GK Hershey

      Ann Allergy Asthma Immunol 97(6):800-6 (2006) PMID 17201240

      Gene-environmental interactions may contribute to the pathogenesis of DA, and gene-gene interactions may modulate this relationship....
    5. Validation of a diffusive sampling method for airborne low-molecular isocyanates using 4-nitro-7-piperazinobenzo-2-oxa-1,3-diazole-impregnat...
      Hartmut H Henneken, Heiko H Hayen, ... Uwe U Karst

      J Chromatogr 1134(1-2):10 (2006) PMID 16996529

      A diffusive sampling method for the determination of low-molecular isocyanates as their 4-nitro-7-piperazinobenzo-2-oxa-1,3-diazole (NBDPZ) derivatives using tandem mass spectrometry (MS/MS) after atmospheric pressure chemical ionisation (APCI) is presented. Isocyanic acid (ICA), methyl isocyanate (...
    6. A facile and clean direct cyanation of heteroaromatic compounds using a recyclable hypervalent iodine(III) reagent.
      Toshifumi T Dohi, Koji K Morimoto, ... Yasuyuki Y Kita

      Chem Pharm Bull (Tokyo) 54(11):1608-10 (2006) PMID 17077564

      The facile and clean direct cyanating reaction of pyrroles and thiophenes has been achieved using a recyclable hypervalent iodine(III) reagent 1b by a simple solid-liquid separation of the products and the reagent.
    7. Effects of simple and complex motion patterns on gene expression of chondrocytes seeded in 3D scaffolds.
      Sibylle S Grad, Sylwester S Gogolewski, ... Markus A MA Wimmer

      Tissue Eng 12(11):3171-9 (2006) PMID 17518631

      This study investigated the effect of unidirectional and multidirectional motion patterns on gene expression and molecule release of chondrocyte-seeded 3D scaffolds. Resorbable porous polyurethane scaffolds were seeded with bovine articular chondrocytes and exposed to dynamic compression, applied wi...
    8. CFTR: Ligand Exchange between a Permeant Anion ([Au(CN)"2]^-) and an Engineered Cysteine (T338C) Blocks the Pore
      José R Serrano, Xuehong Liu, ... David C Dawson

      Biophys J 91(5):12 (2006) PMID 16766608 PMCID 1544293

      We report here that the permeant, pseudohalide anion [Au(CN)2]- can also react with a cysteine engineered into the pore of the CFTR channel. Exposure of Xenopus oocytes expressing the T338C CFTR channel to as little as 100 nM [Au(CN)2]- produced a profound reduction in conductance that was not rever...
    9. Modeling dermal exposure--an illustration for spray painting applications.
      Michael R MR Flynn, Yoshi Y Koto, ... Leena A LA Nylander-French

      J Occup Environ Hyg 3(9):475-80 (2006) PMID 16857646

    10. Dermal, inhalation, and internal exposure to 1,6-HDI and its oligomers in car body repair shop workers and industrial spray painters.
      A Pronk, F Yu, ... D Heederik

      Occup Environ Med 63(9):624-31 (2006) PMID 16728504

      Inhalation exposure was strongly associated with tasks during which aerosolisation occurs. Dermal exposure occurred during tasks that involve direct handling of paint. In car body repair shops associations were found between detectable dermal exposure and glove use (odds ratio (OR) 0.22, 95% confide...
