Journal ArticleDOI
Water: From Clusters to the Bulk
TL;DR: The exploration of structural and binding properties of small water complexes provides a key for understanding bulk water in its liquid and solid phase and for understanding solvation phenomena.
Journal ArticleDOI
Efficient Dehydrogenation of Formic Acid Using an Iron Catalyst
Albert Boddien,Albert Boddien,Dörthe Mellmann,Felix Gärtner,Ralf Jackstell,Henrik Junge,Paul J. Dyson,Gábor Laurenczy,Ralf Ludwig,Matthias Beller +9 more
TL;DR: A highly active iron catalyst system for the liberation of H2 from FA is presented and in situ nuclear magnetic resonance spectroscopy, kinetic studies, and density functional theory calculations are used to explain possible reaction mechanisms.
Journal ArticleDOI
Mesenchymal stem cells display coordinated rolling and adhesion behavior on endothelial cells
Brigitte Rüster,Brigitte Rüster,Stephan Göttig,Stephan Göttig,Ralf Ludwig,Ralf Ludwig,Roxana Bistrian,Roxana Bistrian,Stefanie Müller,Stefanie Müller,Erhard Seifried,Erhard Seifried,Jens Gille,Jens Gille,Reinhard Henschler,Reinhard Henschler +15 more
TL;DR: Intravital microscopy demonstrated the capacity of MSCs to roll and adhere to postcapillary venules in vivo in a mouse model in a P-selectin-dependent manner, indicating that M SCs interact in a coordinated fashion with ECs under shear flow, engaging P- selectin and VCAM-1/VLA-4.
Journal ArticleDOI
Selective Catalytic Hydrogenations of Nitriles, Ketones, and Aldehydes by Well-Defined Manganese Pincer Complexes
Saravanakumar Elangovan,Christoph Topf,Steffen Fischer,Haijun Jiao,Anke Spannenberg,Wolfgang Baumann,Ralf Ludwig,Kathrin Junge,Matthias Beller +8 more
TL;DR: This study describes for the first time specific molecular-defined manganese complexes that allow for the hydrogenation of various polar functional groups and achieves good functional group tolerance, and industrially important substrates, e.g., for the flavor and fragrance industry, are selectively reduced.
Journal ArticleDOI
Anti-inflammatory activity of IgG1 mediated by Fc galactosylation and association of FcγRIIB and dectin-1

TL;DR: It is demonstrated that IgG1 immune complexes, the inhibitory IgG receptor FcγRIIB and the C-type lectin–like receptor dectin-1 suppress C5a receptor (C5aR) functions, and galactosylation of IgG N-glycans is crucial for this inhibitory property of Igg1 ICs.
