Biocrystallography in Switzerland: Achievements and Future Perspectives.

Chimia

Grütter MG.
PMID: 28982439
Chimia (Aarau). 2014 Feb 26;68(1):54-59. doi: 10.2533/chimia.2014.54.

The first protein crystallography group in Switzerland was installed at the Biozentrum of the University of Basel approximately 40 years ago. Since then protein crystallography has grown and matured remarkably and is now established in the molecular biology, biochemistry...

Factors related to work and life satisfaction of veterinary practitioners in Germany.

Veterinary record open

Kersebohm JC, Lorenz T, Becher A, Doherr MG.
PMID: 29018534
Vet Rec Open. 2017 Sep 26;4(1):e000229. doi: 10.1136/vetreco-2017-000229. eCollection 2017.

OBJECTIVES: Veterinary practitioners' working situation is both challenging and changing. They have higher levels of work-related stress and suicide risk than the general population. The proportion of women is increasing, and in Germany especially women and employed veterinarians are...

Structure of a 13-fold superhelix (almost) determined from first principles.

IUCrJ

Schoch GA, Sammito M, Millán C, Usón I, Rudolph MG.
PMID: 25866655
IUCrJ. 2015 Jan 27;2:177-87. doi: 10.1107/S2052252515000238. eCollection 2015 Mar 01.

Nuclear hormone receptors are cytoplasm-based transcription factors that bind a ligand, translate to the nucleus and initiate gene transcription in complex with a co-activator such as TIF2 (transcriptional intermediary factor 2). For structural studies the co-activator is usually mimicked...

Birth weight for gestational age among Flemish twin population.

Facts, views & vision in ObGyn

Doom EC, Delbaere I, Martens G, Temmerman M.
PMID: 24753888
Facts Views Vis Obgyn. 2012;4(1):42-9.

OBJECTIVE: The aim of this study was to develop birth weight references for twins. Mean birth weights of individual twins are lower than those of singletons, hence singleton birth weight curves may not be suitable to assess twin birth...

Dietary habits of polar bears in Foxe Basin, Canada: possible evidence of a trophic regime shift mediated by a new top predator.

Ecology and evolution

Galicia MP, Thiemann GW, Dyck MG, Ferguson SH, Higdon JW.
PMID: 27547372
Ecol Evol. 2016 Jul 28;6(16):6005-18. doi: 10.1002/ece3.2173. eCollection 2016 Aug.

Polar bear (Ursus maritimus) subpopulations in several areas with seasonal sea ice regimes have shown declines in body condition, reproductive rates, or abundance as a result of declining sea ice habitat. In the Foxe Basin region of Nunavut, Canada,...

Sensitivity-based optimization for the design of a grating interferometer for clinical X-ray phase contrast mammography.

Optics express

Arboleda C, Wang Z, Koehler T, Martens G, Van Stevendaal U, Bartels M, Villanueva-Perez P, Roessl E, Stampanoni M.
PMID: 28380987
Opt Express. 2017 Mar 20;25(6):6349-6364. doi: 10.1364/OE.25.006349.

An X-ray grating interferometer (GI) suitable for clinical mammography must comply with quite strict dose, scanning time and geometry limitations, while being able to detect tumors, microcalcifications and other abnormalities. Such a design task is not straightforward, since obtaining...

Free-electron laser design for four-wave mixing experiments with soft-x-ray pulses.

Physical review letters

Marcus G, Penn G, Zholents AA.
PMID: 25062194
Phys Rev Lett. 2014 Jul 11;113(2):024801. doi: 10.1103/PhysRevLett.113.024801. Epub 2014 Jul 10.

We present the design of a single-pass free-electron laser amplifier suitable for enabling four-wave mixing x-ray spectroscopic investigations. The production of longitudinally coherent, single-spike pulses of light from a single electron beam in this scenario relies on a process...

A new approach for the detection of carbon-centered radicals in enzymatic processes using prefluorescent probes.

Photochemistry and photobiology

Ivan MG, Scaiano JC.
PMID: 14626672
Photochem Photobiol. 2003 Oct;78(4):416-9. doi: 10.1562/0031-8655(2003)078<0416:anaftd>2.0.co;2.

In this communication we propose a novel application for prefluorescent probes in the detection of free carbon-centered radicals in enzymatic processes. Prefluorescent probes combine a fluorescent moiety tethered to a paramagnetic nitroxide that acts as a fluorescence quencher. Trapping...

Characterization of the local structures of Ti-MCM-41 and their photocatalytic reactivity for the decomposition of NO into N2 and O2.

The journal of physical chemistry. B

Hu Y, Martra G, Zhang J, Higashimoto S, Coluccia S, Anpo M.
PMID: 16471733
J Phys Chem B. 2006 Feb 02;110(4):1680-5. doi: 10.1021/jp058240u.

Ti-MCM-41 mesoporous molecular sieves were prepared at ambient temperature and were characterized by X-ray absorption near-edge structure and extended X-ray absorption fine structure, UV-vis, Fourier transform infrared spectroscopy, and photoluminescence spectroscopic analyses. It was found that an increase in...

Quick full-field flicker test in glaucoma diagnosis: correlations with perimetry and papillometry.

Journal of glaucoma

Horn FK, Korth M, Martus P.
PMID: 19920599
J Glaucoma. 1994;3(3):206-13.

The value of a full-field flicker stimulus in glaucoma diagnosis was tested. In 69 normals, 60 ocular hypertension, and 50 manifest primary openangle glaucoma patients, the temporal contrast (flicker) thresholds were tested with a sinusoidally flickering white light of...

Square-planar iridium(II) and iridium(III) amido complexes stabilized by a PNP pincer ligand.

Angewandte Chemie (International ed. in English)

Meiners J, Scheibel MG, Lemée-Cailleau MH, Mason SA, Boeddinghaus MB, Fässler TF, Herdtweck E, Khusniyarov MM, Schneider S.
PMID: 21744449
Angew Chem Int Ed Engl. 2011 Aug 22;50(35):8184-7. doi: 10.1002/anie.201102795. Epub 2011 Jul 08.

Squaring the circle: the novel dienamido pincer ligand N(CHCHPtBu(2))(2)(-) affords the isolation of the unusual square-planar iridium(II) and iridium(III) amido complexes [IrCl{N(CHCHPtBu(2))(2)}](n) (n=0 (1), +1 (2)). In contrast, the corresponding iridium(I) complex of the redox series (n=-1) is surprisingly...
