Ziegler BE, Lecours M, Marta RA, Featherstone J, Fillion E, Hopkins WS, Steinmetz V, Keddie NS, O'Hagan D, McMahon TB.
PMID: 27149387
J Am Chem Soc. 2016 Jun 22;138(24):7460-3. doi: 10.1021/jacs.6b02856. Epub 2016 May 12.

Experiments have been carried out in which electrospray ionization has been used to generate ionic complexes of all-cis 1,2,3,4,5,6 hexafluorocyclohexane. These complexes were subsequently mass isolated in a quadrupole ion trap mass spectrometer and then irradiated by the tunable...

Adherence to oral anticoagulant therapy in secondary stroke prevention - impact of the novel oral anticoagulants.

Patient preference and adherence

Luger S, Hohmann C, Niemann D, Kraft P, Gunreben I, Neumann-Haefelin T, Kleinschnitz C, Steinmetz H, Foerch C, Pfeilschifter W.
PMID: 26648702
Patient Prefer Adherence. 2015 Nov 23;9:1695-705. doi: 10.2147/PPA.S88994. eCollection 2015.

BACKGROUND: Oral anticoagulant therapy (OAT) potently prevents strokes in patients with atrial fibrillation. Vitamin K antagonists (VKA) have been the standard of care for long-term OAT for decades, but non-VKA oral anticoagulants (NOAC) have recently been approved for this...

Pigmented villonodular synovitis of the hip.

EFORT open reviews

Steinmetz S, Rougemont AL, Peter R.
PMID: 28461957
EFORT Open Rev. 2017 Mar 13;1(6):260-266. doi: 10.1302/2058-5241.1.000021. eCollection 2016 Jun.

Pigmented villonodular synovitis (PVNS) is a rare disease that can affect any joint, bursa or tendon sheath.The hip is less frequently affected than the knee, and hence is less discussed in scientific journals.PVNS of the hip mainly occurs in...

Influence of Organic Chemicals on Water Molecule Bridges in Soil Organic Matter of a Sapric Histosol.

The journal of physical chemistry. A

Ondruch P, Kucerik J, Steinmetz Z, Schaumann GE.
PMID: 28252302
J Phys Chem A. 2017 Mar 30;121(12):2367-2376. doi: 10.1021/acs.jpca.6b10207. Epub 2017 Mar 16.

Water molecules in soil organic matter (SOM) can form clusters bridging neighboring molecular segments (water molecule bridges, WaMBs). WaMBs are hypothesized to enhance the physical entrapment of organic chemicals and to control the rigidity of the SOM supramolecular structure....

Detection of mutual phase synchronization in multivariate signals and application to phase ensembles and chaotic data.

Physical review. E, Statistical, nonlinear, and soft matter physics

Hutt A, Daffertshofer A, Steinmetz U.
PMID: 14524880
Phys Rev E Stat Nonlin Soft Matter Phys. 2003 Sep;68(3):036219. doi: 10.1103/PhysRevE.68.036219. Epub 2003 Sep 30.

This work presents a method for the detection of mutual phase synchronization in nonstationary time series. We show how the application of a cluster algorithm that considers spatiotemporal structures of data follows from the general condition of phase-synchronized data....

How to compute isomerization energies of organic molecules with quantum chemical methods.

The Journal of organic chemistry

Grimme S, Steinmetz M, Korth M.
PMID: 17286442
J Org Chem. 2007 Mar 16;72(6):2118-26. doi: 10.1021/jo062446p. Epub 2007 Feb 08.

The reaction energies for 34 typical organic isomerizations including oxygen and nitrogen heteroatoms are investigated with modern quantum chemical methods that have the perspective of also being applicable to large systems. The experimental reaction enthalpies are corrected for vibrational...

A direct measurement of the universe's expansion history could be made by observing in real time the evolution of the cosmological redshift of distant objects. However, this would require measurements of Doppler velocity drifts of approximately 1 centimeter per...

Mechanistic insights into the palladium-induced domino reaction leading to ketones from benzyl beta-ketoesters: first characterization of the enol as an intermediate.

The Journal of organic chemistry

Detalle JF, Riahi A, Steinmetz V, Hénin F, Muzart J.
PMID: 15387574
J Org Chem. 2004 Oct 01;69(20):6528-32. doi: 10.1021/jo049464w.

The monitoring by UV spectroscopy of the Pd-catalyzed hydrogenolysis in acetonitrile of 2-methyl-2-benzyloxycarbonyl-1-indanone and 2-methyl-2-benzyloxycarbonyl-1-tetralone showed the successive formation of corresponding beta-ketoacids and enols to deliver finally the ketones. Some factors which influence the stability of the intermediates are...
