Osbahr I, Krause J, Bachmann K, Gutzmer J.
PMID: 26428438
Microsc Microanal. 2015 Oct;21(5):1080-95. doi: 10.1017/S1431927615000719.

Identification and accurate characterization of platinum-group minerals (PGMs) is usually a very cumbersome procedure due to their small grain size (typically below 10 µm) and inconspicuous appearance under reflected light. A novel strategy for finding PGMs and quantifying their...

Redirection of Metabolic Hydrogen by Inhibiting Methanogenesis in the Rumen Simulation Technique (RUSITEC).

Frontiers in microbiology

Guyader J, Ungerfeld EM, Beauchemin KA.
PMID: 28352256
Front Microbiol. 2017 Mar 14;8:393. doi: 10.3389/fmicb.2017.00393. eCollection 2017.

A decrease in methanogenesis is expected to improve ruminant performance by allocating rumen metabolic hydrogen ([2H]) to more energy-rendering fermentation pathways for the animal. However, decreases in methane (CH

A Fluorination/Aryl Migration/Cyclization Cascade for the Metal-Free Synthesis of Fluoro-Benzoxazepines.

Chemistry (Weinheim an der Bergstrasse, Germany)

Ulmer A, Brunner C, Arnold AM, Pöthig A, Gulder T.

Chemistry. 2016 Mar 07;22(11):3660-4. doi: 10.1002/chem.201504749. Epub 2015 Dec 23.

Fluorinated organic molecules are of high interest for many applications across chemical and medical disciplines. Efficient methods for the synthesis of such compounds are thus needed. Within this work, application of the bench-stable cyclic hypervalent iodine(III) fluoro reagent 1...

Ultra-high-Q thin-silicon nitride strip-loaded ring resonators.

Optics letters

Stefan L, Bernard M, Guider R, Pucker G, Pavesi L, Ghulinyan M.
PMID: 26176458
Opt Lett. 2015 Jul 15;40(14):3316-9. doi: 10.1364/OL.40.003316.

We report on the design, fabrication, and characterization of thin Si3N4 ultra-high-quality (UHQ) factor ring resonators monolithically integrated on a silicon chip. The devices are based on a strip-loaded configuration and operate at both near-infrared (NIR) and third-telecom wavelengths....

Curdlan sulphate modulates protein synthesis and enhances NF-kappaB and C/EBP binding activity in HepG2 cells.

Mediators of inflammation

PMID: 18472835
Mediators Inflamm. 1997;6(1):58-63. doi: 10.1080/09629359791947.

In human hepatoma HepG2 cell line curdlan sulphate enhances basal and interleukin-6-stimulated fibrinogen and antichymotrypsin (ACT) synthesis, slightly increases basal ceruloplasmin production and exerts only minor effects on alpha-1-proteinase inhibitor and transferrin. Curdlan sulphate may, at least in part,...

Using GRENOUILLE to characterize asymmetric femtosecond pulses undergoing self- and cross-phase modulation in a polarization-maintaining optical fiber.

Optics express

PMID: 19471427
Opt Express. 2003 Nov 17;11(23):3063-73. doi: 10.1364/oe.11.003063.

Self- and Cross-phase modulation of asymmetric femtosecond pulses (~ 810 nm) propagating through a birefringent single-mode optical fiber (~ 6.9 cm) is studied both experimentally (using GRENOUILLE) and numerically (by solving a set of coupled nonlinear Schrödinger equations or...

The effect of feeding supra-nutritional levels of α-tocopheryl acetate on its deposition in two porcine muscles of different metabolic rates (m. longissimus dorsi and m. psoas major) and the effect on meat quality (lipid oxidation, colour stability and drip...

Adenosine triphosphatase in the phloem of Cucurbita.

PMID: 24474397
Planta. 1973 Sep;110(3):189-204. doi: 10.1007/BF00387632.

The distribution of adenosine triphosphatase (ATPase) activity in the phloem of petioles and minor veins of Cucurbita maxima has been studied using a lead phosphate precipitation procedure. ATPase activity was localized in sieve elements, companion cells and parenchyma cells....
