Molecular Structures and Ion Mobility Cross Sections: Analysis of the Effects of He and N2 Buffer Gas.

Analytical chemistry

Bleiholder C, Johnson NR, Contreras S, Wyttenbach T, Bowers MT.
PMID: 26076363
Anal Chem. 2015 Jul 21;87(14):7196-203. doi: 10.1021/acs.analchem.5b01429. Epub 2015 Jun 29.

An empirically observed correlation between ion mobility cross sections in helium and nitrogen buffer gases was examined as a function of temperature, molecular size, and shape. Experimental cross sections were determined for tetraglycine, bradykinin, angiotensin 2, melittin, and ubiquitin...

Instrumental neutron-activation determination of phosphorus in biological materials by bremsstrahlung measurement.

Talanta

Bajo S, Wyttenbach A.
PMID: 18964609
Talanta. 1988 Oct;35(10):747-51. doi: 10.1016/0039-9140(88)80178-4.

The determination of phosphorus in biological materials by instrumental neutron-activation analysis by the reaction (31)P (n, lambda)(32)p is described. The bremsstrahlung produced by (32)P is measured in a well-type NaI(T1) detector. The samples are measured in the polyethylene irradiation...

A quarter of a century of job transitions in Germany.

Journal of vocational behavior

Kattenbach R, Schneidhofer TM, Lücke J, Latzke M, Loacker B, Schramm F, Mayrhofer W.
PMID: 24493876
J Vocat Behav. 2014 Feb;84(1):49-58. doi: 10.1016/j.jvb.2013.11.001.

By examining trends in intra-organizational and inter-organizational job transition probabilities among professional and managerial employees in Germany, we test the applicability of mainstream career theory to a specific context and challenge its implied change assumption. Drawing on data from...

Publisher Correction: Evolution of chalcone isomerase from a noncatalytic ancestor.

Nature chemical biology

Kaltenbach M, Burke JR, Dindo M, Pabis A, Munsberg FS, Rabin A, Kamerlin SCL, Noel JP, Tawfik DS.
PMID: 29760514
Nat Chem Biol. 2018 Oct;14(10):988. doi: 10.1038/s41589-018-0079-3.

In the version of this article originally published, the number for the equal contributions footnote was missing for Miriam Kaltenbach and Jason R. Burke in the author list. The error has been corrected in the PDF and print versions...

Spectrally resolved helium absorption from the extended atmosphere of a warm Neptune-mass exoplanet.

Science (New York, N.Y.)

Allart R, Bourrier V, Lovis C, Ehrenreich D, Spake JJ, Wyttenbach A, Pino L, Pepe F, Sing DK, Lecavelier des Etangs A.
PMID: 30523080
Science. 2018 Dec 21;362(6421):1384-1387. doi: 10.1126/science.aat5879. Epub 2018 Dec 06.

Stellar heating causes atmospheres of close-in exoplanets to expand and escape. These extended atmospheres are difficult to observe because their main spectral signature-neutral hydrogen at ultraviolet wavelengths-is strongly absorbed by interstellar medium. We report the detection of the near-infrared...

Attenuation Correction Approaches for Serotonin Transporter Quantification With PET/MRI.

Frontiers in physiology

Rischka L, Gryglewski G, Berroterán-Infante N, Rausch I, James GM, Klöbl M, Sigurdardottir H, Hartenbach M, Hahn A, Wadsak W, Mitterhauser M, Beyer T, Kasper S, Prayer D, Hacker M, Lanzenberger R.
PMID: 31824335
Front Physiol. 2019 Nov 22;10:1422. doi: 10.3389/fphys.2019.01422. eCollection 2019.

BACKGROUND: Several MR-based attenuation correction (AC) approaches were developed to conquer the challenging AC in hybrid PET/MR imaging. These AC methods are commonly evaluated on standardized uptake values or tissue concentration. However, in neurotransmitter system studies absolute quantification is...

The Growing Field of Imaging of Atherosclerosis in Peripheral Arteries.

Angiology

Cattaneo M, Wyttenbach R, Corti R, Staub D, Gallino A.
PMID: 29783854
Angiology. 2019 Jan;70(1):20-34. doi: 10.1177/0003319718776122. Epub 2018 May 21.

In the past decades, peripheral arteries have represented a model for the comprehension of atherosclerosis as well as for the development of new diagnostic imaging modalities and therapeutic strategies. Peripheral arteries may represent a window to study atherosclerosis. Pathology...

A brain-penetrant microtubule-targeting agent that disrupts hallmarks of glioma tumorigenesis.

Neuro-oncology advances

Horne EA, Diaz P, Cimino PJ, Jung E, Xu C, Hamel E, Wagenbach M, Kumasaka D, Wageling NB, Azorín DD, Winkler F, Wordeman LG, Holland EC, Stella N.

BACKGROUND: Glioma is sensitive to microtubule-targeting agents (MTAs), but most MTAs do not cross the blood brain barrier (BBB). To address this limitation, we developed the new chemical entity, ST-401, a brain-penetrant MTA.METHODS: Synthesis of ST-401. Measures of MT...
